Detailed Description

The invention is further illustrated by the following examples, which are not intended to limit the scope of the invention.

The embodiment of the invention provides an exhaust pipe black carbon measurement interface device, which is used for solving the problem that smoke leakage risk is increased due to the fact that one or more interfaces are required to be additionally arranged on the side wall of a main exhaust pipe 1 when carbon content is measured. Referring to fig. 1 to 2, the exhaust pipe black carbon measurement interface device mainly includes a main exhaust pipe 1, a three-way valve 2, and a sampling tool unit 3. The protruding end of the main exhaust pipe 1 is mounted with a common flange. The three-way valve 2 comprises a first connection port, a second connection port and a third connection port. The first connecting port is fixedly connected with the common flange. The second connector is fixedly connected with an external cigarette ash rainwater cabinet or a liquid-sealed tank, so that the main exhaust pipe 1 is communicated with the cigarette ash rainwater cabinet or the liquid-sealed tank, and related functions of an original pipe section are not affected. The sampling tool part 3 comprises a sampling piece 32 and a connecting piece 31, wherein the connecting piece 31 is in a rod shape, and the connecting piece 31 is fixedly connected with the sampling piece 32. When the content of black carbon in the main exhaust pipe 1 is measured, the connecting piece 31 penetrates through the first connecting port, the third connecting port and the common flange, one end with the sampling piece 32 extends into the main exhaust pipe 1, and the black carbon in the main exhaust pipe 1 is sampled by the sampling piece 32. During testing, the connecting piece 31 and the main exhaust pipe 1 are detachably connected. After the test is completed, the sampling member 32 is taken out and detected to obtain the content of the black carbon in the main exhaust pipe 1.

In particular use, the connecting member 31 is a screw, and in order to obtain more accurate sampling data, it is preferable to locate the sampling member 32 at the center of the main exhaust pipe 1.

In a preferred embodiment, a cylindrical sampling tube part 4 is fitted over the connector 31 to protect the connector 31, and the upper end of the sampling tube part 4 is fixedly connected to the third connection port. Since the upper end of the connecting rod is connected with the sampling piece 32, the upper end of the connecting piece 31 needs to be extended out of the sampling tube part 4 and into the main exhaust pipe 1 for testing. For ease of installation, the lower end of the connector 31 protrudes beyond the lower end of the sampling tube portion 4, and the lower end of the sampling tube portion 4 is connected to the connector 31.

In a preferred embodiment, the sampling tube portion 4 has an elongated tubular structure, and the sampling tube portion 4 is divided into an upper cylindrical sampling tube portion 41 and a distal cylindrical sampling tube portion 42 to facilitate storage of the sampling tube portion 4. The upper sampling tube portion 41 and the end sampling tube portion 42 are fixedly connected and communicated. The upper end of the upper sampling tube part 41 is connected with the third connecting port through a modified blind flange 7. For the stability of installation, the two ends of the blind flange 7 are required to be fixedly connected with the third connecting port and the upper end of the upper sampling pipe part 41. Before testing, the upper end of the connecting piece 31 extends out of the upper end of the upper sampling pipe part 41 and then extends into the main exhaust pipe 1. In order to facilitate the penetration of the connecting piece 31, a first through hole 71 is formed in the inner ring of the modified blind flange 7, and the first through hole 71 is communicated with the three-way valve 2. The connection member 31 may sequentially penetrate the first through hole 71, the third connection port, the first connection port, and the common flange, and allow the sampling member 32 to enter the main exhaust pipe 1. The lower end of the connector 31 protrudes out of the lower end of the end sampling tube part 42, and the connector 31 is fixedly connected to the end sampling tube part 42.

In particular use, the fixing member 6 is a clip.

In order to prevent the gas in the main exhaust pipe 1 from leaking from the upper sampling pipe portion 41 before the connection member 31 is inserted into the main exhaust pipe 1, a first valve 5 is installed in the upper sampling pipe portion 41 to control the opening and closing of the upper sampling pipe portion 41.

In particular use, the first valve 5 is a ball valve.

As a preferred embodiment, soot clogging occurs when the connector 31 is installed. To avoid damage to the sampling member 32, it is often necessary to clean the clogged area of soot. The compressed air pipe 8 is fixedly communicated with the end section sampling pipe part 42. One end of the compressed air pipe 8 is fixedly connected with the end sampling pipe part 42, and the other end is detachably connected with the compressed air part. A second valve 9 is fixedly connected to the compressed air pipe 8, and the second valve 9 is used for controlling the on-off of the compressed air part and the tail sampling pipe part 42.

During sampling, if too much soot is accumulated, the second valve 9 may also be opened for soot blowing. With the adoption of the structure, the problem that the sampling tool part 3 is difficult to insert due to soot accumulation is solved.

In a preferred embodiment, the lower end of the end sampling tube portion 42 is connected to the connector 31 by a seal-fixed end cap 10. The lower end of the last sampling tube part 42 is provided with a section of external thread, and the first threaded hole formed in the sealing and fixing end cover 10 is an internal thread. The internal thread formed by the seal fixing end cover 10 can be tightly connected with the external thread at the lower end of the end section sampling pipe part 42, thereby playing the role of seal fixing. When the sampling piece 32 reaches the optimal sampling position, the connecting piece 31 can be in threaded connection with the second threaded hole of the seal fixing end cover 10, and the connecting rod can be fixed on the seal fixing end cover 10. If the phenomenon of soot blockage occurs in the installation process, the sealing and fixing end cover 10 and the tail sampling pipe part 42 can be fixedly connected firstly, and then soot blowing is performed, so that the sampling pipe part 4 has good sealing performance in the soot blowing process.

In particular, in order to ensure that the sampling piece 32 can reach the optimal sampling position in the main exhaust pipe 1, the connecting piece 31 with a longer length can be selected, and the lower end of the connecting piece 31 extends out of the sealing and fixing end cover 10.

In a preferred embodiment, the first threaded hole and the second threaded hole are coaxial.

In a preferred embodiment, the cork 11 is located inside the end sampling tube portion 42 and at the lower end of the end sampling tube portion 42. The soft plug 11 can prevent the high temperature of more than 450 ℃, and the soft plug 11 is provided with a second through hole through which the connecting piece 31 penetrates.

As a preferred embodiment, to prevent the cork 11 from shifting in the end sampling tube portion 42, an annular baffle 12 is provided in the end sampling tube portion 42. The side wall of the baffle 12 is fixedly connected with the inner wall of the last-stage sampling pipe part 42, and the inner ring of the baffle 12 is coaxial with the second through hole. The two ends of the soft plug 11 are respectively abutted against the end face of the baffle plate 12 and the sealing and fixing end cover 10.

The embodiment of the invention also provides a marine engine room which comprises the exhaust pipe black carbon measurement interface device.

The first connector of the three-way valve 2 is fixedly connected with the common flange, and the second connector of the three-way valve 2 is fixedly connected with the cigarette ash rainwater cabinet or the liquid-sealed tank, so that the function of the pipe section is not influenced in the sampling process. Before sampling, the upper end of the upper sampling pipe part 41 is connected with the third connecting port through the improved blind flange 7. Then, the connecting member 31 penetrates the inner soft plug 11 at the lower end of the end sampling tube part 42 and then the sampling member 32 is mounted thereon, so that the sampling member 32 is prevented from being damaged by first mounting the sampling member 32 and then inserting the soft plug 11. After the connecting piece 31 runs through the soft plug 11, the ball valve positioned on the upper sampling pipe part 41 is opened, the upper end of the connecting piece 31 is stretched into the upper sampling pipe part 41, then the upper sampling pipe part 41 is stretched out and sequentially runs through the first through hole 71 of the improved blind flange 7, the third connector and the first connector of the three-way valve 2 and the common flange, finally, the sampling piece 32 is stretched into the main exhaust pipe 1, and the upper sampling pipe part 41 and the last sampling pipe part 42 are fixedly connected through a clamp. During installation, if the soot blockage phenomenon occurs, the sealing and fixing end cover 10 is firstly connected with the tail sampling pipe part 42 in a threaded mode, then the second valve 9 is opened, and the sampling pipe part 4 is subjected to soot blowing by using the compressed air part. During sampling, the micro-grid carbon film in the sampling piece 32 is used for collecting a black carbon sample, and the micro-grid carbon film faces the exhaust direction for about 30 seconds. After sampling, the connecting piece 31 is rotated, the sampling piece 32 is gradually screwed out, the first valve 5 is closed, the clamp is loosened, and the micro-grid carbon film in the sampling piece 32 is taken out. The sampling piece 32 is cleaned with alcohol, a new micro-grid carbon film is installed, and the next round of testing is performed, and so on. During sampling, if too much soot is accumulated, the second valve 9 may also be opened for soot blowing.
