The utility model has the advantages of, the combination of the U type pipe of adopting the exhaust chamber, inversion and buffer, marsh gas gets into the buffer through the U type pipe of inversion, and a plurality of through-holes through the buffer lateral wall are discharged to the exhaust chamber, and by discharging after the liquid filtration buffering in the exhaust chamber, can effectually get rid of hydrogen sulfide gas body, and buffering effect is good, and the security is stronger.

Description

Water seal device of anaerobic tank

Technical Field

The utility model belongs to the technical field of the water treatment technique and specifically relates to an anaerobic jar water seal arrangement is related to.

Background

The UASB type anaerobic sludge bed reactor is a high-efficiency sewage anaerobic treatment reactor, and is widely applied to the treatment of high-concentration organic wastewater at present, and has the advantages of low energy consumption, stable operation, low sludge production and the like, the effective removal rate of COD can reach more than 80%, sewage enters a water reactor from the bottom and flows out from the top, microorganisms in a granular sludge area at the bottom of the reactor and a suspended sludge area decompose organic matters in the sewage in large quantity, so that a large amount of methane gas is generated, the methane gas is collected by a gas collection pipeline at the top of a three-phase separator, and the methane gas is discharged through a water-sealed tank and then is combusted and the like for comprehensive utilization, the existing UASB water-sealed tank has a too simple structure, and only plays a flame-retardant effect, and has the defects of poor safety protection effect, weak hydrogen sulfide gas removal capability and the like.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem, provide an anaerobic jar water seal arrangement, it is good to have the security performance, advantage that hydrogen sulfide removal capacity is strong.

In order to achieve the above purpose, the utility model adopts the following technical scheme: an anaerobic tank water seal apparatus comprising:

the bottom of the exhaust chamber is provided with a water inlet, and the upper end of the exhaust chamber is provided with an exhaust port and a first jack;

one end of the inverted U-shaped pipe penetrates through the first jack and extends into the exhaust chamber, a buffer is arranged at the port, and a plurality of through holes are formed in the side wall of the buffer;

and the lower end of the exhaust pipe is communicated with the exhaust port.

Preferably, the upper end of the buffer is provided with a second jack, the lower end of the buffer is closed, and one end of the U-shaped pipe penetrates through the second jack and extends into the buffer.

The utility model has the advantages of, the combination of the U type pipe of adopting the exhaust chamber, inversion and buffer, marsh gas gets into the buffer through the U type pipe of inversion, and a plurality of through-holes through the buffer lateral wall are discharged to the exhaust chamber, and by discharging after the liquid filtration buffering in the exhaust chamber, can effectually get rid of hydrogen sulfide gas body, and buffering effect is good, and the security is stronger.

wherein, 1-UASB anaerobic jar body; 2-a three-phase separator; 3-U-shaped pipe; 4-an exhaust chamber; 41-exhaust port; 42-a first receptacle; 5-a water inlet; 6-a buffer; 61-a second receptacle; 7-an exhaust pipe; 8-water seal liquid level.

Detailed Description

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

As shown in figure 1, the anaerobic tank water seal device consists of an exhaust chamber 4, an inverted U-shaped pipe 3, a buffer 6 and an exhaust pipe 7, and is arranged at the upper end part of a UASB anaerobic tank body 1, wherein the exhaust chamber 4 is arranged at the upper part of a three-phase separator 2, the bottom of the exhaust chamber is provided with a water inlet 5, and the upper end of the exhaust chamber is provided with an exhaust port 41 and a first jack 42; the U-shaped pipe 3 is inverted, one end of the U-shaped pipe passes through the first jack and extends into the exhaust chamber 4, a buffer 6 is arranged at the port of the U-shaped pipe, the other end of the U-shaped pipe 3 is communicated with an air outlet of the three-phase separator 2, and a plurality of through holes (not shown in the figure) are formed in the side wall of the buffer 6; the lower end of the exhaust pipe 7 communicates with the exhaust port 41. The upper end of the buffer 6 is provided with a second jack 61, the lower end is closed, and one end of the U-shaped pipe 3 passes through the second jack 61 and extends into the buffer 6. The water seal liquid level 8 is lower than the upper end of the exhaust chamber 4. In the using process, the biogas is discharged to the exhaust chamber 4 through the inverted U-shaped pipe 3 via a plurality of through holes on the side wall of the buffer 6, filtered and buffered by liquid, and then discharged through the exhaust pipe 7. Can effectively remove hydrogen sulfide gas, has good buffering effect and stronger safety.

Although the specific embodiments of the present invention have been described above with reference to the accompanying drawings, the scope of the present invention is not limited thereto, and for some technical contents known to those skilled in the art, the detailed description is omitted here, and it should be understood by those skilled in the art that various modifications or variations that can be made by those skilled in the art without inventive work are still within the scope of the present invention.

Claims
