Technical Field

The invention relates to a drainage and drainage system for coal chemical gasification pretreatment, and belongs to the technical field of coal chemical gas pretreatment.

Background

As is well known, refrigeration in the coal chemical industry pretreatment drainage system is the most important link at present, and most of gas to be measured in the coal chemical industry can only appear in the appropriate temperature range of a measuring instrument after being cooled by a refrigeration technology.

However, because the sample gas contains air water molecules, the sample gas is condensed into liquid drops when meeting the condensation, the water condensed at the bottom of the vortex refrigeration tank needs to be discharged, and the water in the refrigeration tank is difficult to discharge even if the water in the refrigeration tank is increased to a certain degree due to double reasons of negative pressure and water tension, so that the problem often occurs even if a water pump filter is additionally arranged below the refrigeration tank, and even in serious cases, the water which cannot be discharged below is directly pumped into the instrument due to the negative pressure, so that the water enters the instrument.

And current technical scheme is with the direct discharge instrument of drainage export, corresponds normal outside air pressure, and in fact many times the instrument in order to let gas transport smoothly, inside all is the negative pressure compared with the outside, and this has also led to the outlet outside atmospheric pressure too big, and hard is the vacuum that forms in the below, has hindered the drainage of water.

Disclosure of Invention

Aiming at the problems, the invention mainly overcomes the defects in the prior art and provides a coal chemical gasification pretreatment drainage system with unsmooth drainage.

The technical scheme provided by the invention for solving the technical problems is as follows: coal chemical industry gasification preliminary treatment drainage flowing back system, including filtering separation device, total delivery pipe, tee bend, vortex refrigeration jar and install vortex tube on the vortex refrigeration jar, vortex refrigeration tank bottoms portion is equipped with cooling drain pipe, appearance gas admission pipe and filtering separation device intercommunication, filtering separation device bottom is equipped with the discharge pipe, cooling drain pipe, total delivery pipe communicate with the tee bend respectively.

The further technical proposal is that the discharge pipe and the cooling water discharge pipe are both provided with valves.

The further technical scheme is that the valve is a needle valve.

The further technical scheme is that the cooling water drainage pipe adopts a drainage pipe with a large aperture.

The invention has the following beneficial effects: the invention can ensure that the pretreatment system can normally operate and also effectively avoid the problem that the cooling liquid cannot be discharged or even flows backwards into the instrument.

Detailed Description

The present invention will be further described with reference to the following examples and the accompanying drawings.

As shown in fig. 1, the coal chemical gasification pretreatment drainage and drainage system comprises a filtering and separating device 5, a main discharge pipe 6, a tee joint 7, a vortex refrigeration tank 1 and a vortex pipe 2 installed on the vortex refrigeration tank 1, wherein a cooling drain pipe 3 and a sample gas inlet pipe 4 are arranged at the bottom of the vortex refrigeration tank 1, the sample gas inlet pipe 4 is communicated with the filtering and separating device 5, a discharge pipe 8 is arranged at the bottom of the filtering and separating device 5, and the discharge pipe 8, the cooling drain pipe 3 and the main discharge pipe 6 are respectively communicated with the tee joint 7.

The cooling water discharge pipe 3 is connected to the main discharge pipe 6 through the tee joint 7, the main discharge pipe 6 and the water discharge system are in a same system, but the flow of the main discharge pipe 6 is larger, so that the pressure is smaller than the internal normal point, a reasonable pressure difference interval is formed compared with the pressure of the cooling water discharge pipe 3, and water is easier to discharge.

In order to control the discharge, it is preferable that the discharge pipe 8 and the cooling water discharge pipe 3 are provided with valves 9, and the valves 9 are needle valves.

In order to further improve the drainage efficiency in this embodiment, it is preferable that the cooling drain pipe 3 is a drain pipe with a large aperture. Therefore, the generation of water tension factors can be reduced as much as possible by enlarging the aperture of the lower drainage pipeline.

Although the present invention has been described with reference to the above embodiments, it should be understood that the present invention is not limited to the above embodiments, and those skilled in the art can make various changes and modifications without departing from the scope of the present invention.
