The present invention is described in terms of particular embodiments, other advantages and features of the invention will become apparent to those skilled in the art from the following disclosure, and it is to be understood that the described embodiments are merely exemplary of the invention and that it is not intended to limit the invention to the particular embodiments disclosed. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, fig. 1 is a schematic view of an effluent measuring device of a kerosene vapor phase drying apparatus according to an embodiment of the present invention.

The embodiment of the invention provides a water outlet measuring device of kerosene vapor phase drying equipment, which comprises: the system comprises an exhaust separation device 110, a condensing device 120, a direct drain valve 130, a measurement water inlet valve 140, a measurement device 150 and a measurement drain valve 160; the exhaust separation device 110 is connected with the tail end of the preceding stage vacuum pump and is used for collecting liquid water; the condensing device 120 is disposed inside the cavity of the exhaust gas separation device 110, and is configured to condense water vapor introduced into the exhaust gas separation device 110 into liquid water; the direct drain valve 130 is configured to control whether to directly drain liquid water inside the chamber out of the chamber of the exhaust gas separation device 110; the measurement water inlet valve 140 is connected to the cavity of the exhaust separation device 110 and the measurement device 150, and is used for controlling whether to discharge the liquid water into the measurement device 150 or not so as to facilitate the measurement of the measurement device 150; the measuring drain valve 160 is connected to a drain end of the measuring device 150 for draining.

Further, in one embodiment, the effluent measuring device 150 further comprises, a valve controller; the direct drain valve 130 is a first electrically controlled valve; the measuring water inlet valve 140 is a second electric control valve; the measuring drain valve 160 is a third electric control valve; the valve controller is used for controlling the first electric control valve, the second electric control valve and the third electric control valve to be opened and closed.

Specifically, when a valve controller is applied, when the kerosene vapor phase drying device is in a heating stage, the valve controller controls the first electrically-controlled valve to be opened to discharge the liquid water to a storage device; when the kerosene vapor phase drying device is in a high vacuum stage, after the roots pump is started, the second electric control valve is controlled to be opened, and the liquid water is discharged into the measuring device 150 so that the measuring device 150 can measure.

Further, the condensing unit 120 includes: a water inlet valve 121, a water outlet valve 122 and an evaporation pipe 123; the water inlet valve 121 is used for controlling the entry of chilled water, and the water outlet valve 122 is used for controlling the discharge of chilled water; the evaporation pipe 123 is disposed in the cavity of the exhaust gas separation device 110, and when the chilled water flows through the evaporation pipe 123, the water vapor inside the cavity of the exhaust gas separation device 110 is liquefied. The evaporation tube may be capillary or curved thin tube.

In practice, the measurement of the liquid may be performed using a magnetostrictive liquid level gauge, in particular the measuring device 150 comprises: the liquid level meter comprises a magnetostrictive liquid level meter and a liquid level meter cylinder, wherein the liquid level meter cylinder is vertically arranged; the magnetostrictive liquid level meter is arranged in the liquid level meter cylinder; the density of a floating ball of the magnetostrictive liquid level meter is 0.7.

Since the float density of the magnetostrictive liquid level meter of the measuring device 150 is 0.7, it is not measurable if oil is taken, and the liquid level meter needs to be protected from detecting the condition of the oil taken, if the liquid level of the measuring device 150 is too high. Forced venting is required. Therefore, a protective liquid level meter can be arranged in the effluent measuring device 150; the protection liquid level meter is used for sending out an alarm signal when the liquid level of the measuring device 150 exceeds a preset value. Can also be used for

The height and the accumulated water volume of the magnetic hysteresis liquid level meter can be calibrated. The measurement precision of the magnetic hysteresis liquid level meter is matched with the collecting cylinder to meet the following conditions: calibrating a water quality conversion value under each scale according to the minimum measurement precision; when the water surface rises to a height with minimum metering precision, the converted water mass is not more than 2 g. In particular, a height-volume-mass conversion module may be applied for converting the measurement signal of the magnetostrictive liquid level gauge into a mass.

The volume of the measuring cylinder must be small because the high vacuum has little water outlet and the precision must be high. Compressed air is required to forcibly discharge the liquid quickly during the liquid discharge process. Therefore, a suction drain pump may be used; the air and water pumping and discharging pump is connected with the measuring and water discharging valve 160; when the door of the measurement drain valve 160 is opened, the suction drain pump is started to drain the measurement device 150.

The embodiment of the invention provides a water outlet measuring device of kerosene vapor phase drying equipment, which can directly discharge liquid which does not need to be measured by using a direct drain valve, thereby reducing the burden of the measuring device, scientifically measuring the discharged water aiming at the characteristics of the kerosene vapor phase drying process and reducing the possibility that the measuring device is blocked.

In another embodiment of the present invention, an embodiment of the present invention provides a kerosene vapor phase drying apparatus provided with the effluent measuring device of the kerosene vapor phase drying apparatus as described in any one of the above.

Although the invention has been described in detail above with reference to a general description and specific examples, it will be apparent to one skilled in the art that modifications or improvements may be made thereto based on the invention. Accordingly, such modifications and improvements are intended to be within the scope of the invention as claimed.
