Description

Liquid seal emptying device

Technical Field

The utility model belongs to the technical field of environmental protection, and relates to a liquid seal emptying device.

Background

With the development of the existing industrial economy and the increasingly outstanding conflict of social safety, the requirements of people on the safety production of chemical industry are higher and higher, and particularly, the safety requirements of the state on the chemical industry are more and more strict due to endless safety accidents in recent years. Under the condition, chemical enterprises continuously improve the safety performance of production equipment in order to survive, develop and improve the safety factor of the existing production conditions.

The byproduct gas in the production process of some chemical products is directly discharged into the atmosphere, so that atmospheric pollution and resource waste are caused, and the tail gas contains flammable and explosive components and has potential safety hazard when being directly discharged. The tail gas tank with a liquid seal device is often adopted for caching, but the liquid seal tail gas tank commonly used at present has the following defects: (1) when the pressure in the water sealing device is ultrahigh, water sealing liquid is easy to flush into the emptying header pipe and form a liquid sealing section in the emptying header pipe, so that the pressure in the tail gas tank cannot be released as soon as possible, and safety accidents are easy to cause; (2) when the pressure in the water seal device suddenly rises and exceeds the upper limit value of the water seal liquid level, water in the water seal device is sprayed out, so that the ground environment is polluted, and the sprayed polluted water is difficult to collect and treat; (3) the water seal device needs to periodically and manually supplement liquid seal water, so that the operation is inconvenient, and safety accidents are easily caused when the water body in the water seal device cannot meet the liquid seal requirement due to careless supervision of workers.

Therefore, how to solve the above problems is an important problem to be solved by those skilled in the art.

Disclosure of Invention

In order to solve the problems in the prior art, the utility model aims to provide a liquid seal emptying device.

In order to achieve the purpose, the utility model provides the following technical scheme: a liquid seal emptying device comprises a liquid seal tank; a liquid seal chamber and a pressure relief area are arranged in the liquid seal tank; a liquid inlet and an air outlet are formed in the upper part of the liquid seal tank; the liquid seal chamber is arranged at a distance from the inner wall of the liquid seal tank, the liquid seal chamber is used for accommodating a liquid seal medium, the upper part of the liquid level in the liquid seal chamber is a gas area and is communicated with the liquid injection port, and the lower part of the liquid level is a liquid area; a tooth-shaped structure is arranged below the liquid level in the liquid seal chamber; the pressure relief area is arranged between the liquid sealing chamber and the inner wall of the liquid sealing tank; the exhaust port is communicated with the pressure relief area, and a water outlet is formed in the side wall of the liquid seal tank corresponding to the liquid level surface; the liquid seal tank is positioned at the water outlet; and a flange connected with the pipeline is arranged on one side wall of the opposite side at a distance.

Furthermore, a liquid level meter for monitoring the liquid level height of the liquid in the liquid seal tank is further arranged on the side wall of the liquid seal tank.

Further, the tooth-shaped structure is a 26-tooth structure.

Furthermore, one end of the exhaust port is communicated with the pressure relief chamber, and the other end of the exhaust port is communicated with the outside.

Furthermore, the bottom of the liquid seal tank is provided with an emptying valve used for discharging liquid in the tank body.

Compared with the prior art, the utility model has the beneficial effects that:

when the top of the pressure relief chamber is connected with a pipeline, the air pressure in the liquid sealing tank is increased, the liquid level is increased, the upper air is pressed downwards to the tooth-shaped structure, and the redundant air is discharged from the tooth-shaped structure to the pressure relief chamber and then is discharged along the exhaust port. When the liquid level is high, a part of liquid is discharged from the water outlet on the side wall of the liquid seal tank.

After the liquid seal layer in the liquid seal chamber of the structure is extruded and damaged, gas sequentially enters the pressure relief chamber and overflows to the outside through the tillite port, and once the internal pressure returns to be normal, the liquid seal layer is formed again, so that the gas pressure in the liquid seal tank is ensured to be within a safe pressure range.
