Negative pressure water seal tank

Abstract

The invention relates to the technical field of chemical equipment, in particular to a negative pressure water seal tank. The water seal tank comprises a tank body, a cover plate, an inner cylinder and an outer cylinder, wherein the tank body comprises a bottom plate and a side wall, the side wall is fixedly connected to the bottom plate, the inner cylinder is fixedly connected to the upper surface of the bottom plate of the tank body, the cover plate is fixedly connected to the top of the side wall of the tank body, the outer cylinder is fixedly connected to the cover plate, the inner cylinder is sleeved with the outer cylinder, a gap is formed between the bottom surface of the outer cylinder and the upper surface of the bottom plate of the tank body, a gap is formed between the inner cylinder and the outer cylinder, a sealing cap is arranged at the top of the inner cylinder, a condensate inlet is formed in the top of the outer cylinder, a water injection opening is formed in the cover plate, an overflow opening is formed in the upper portion of the side wall of the tank body, and an exhausting opening is formed in the lower portion of the side wall of the tank body. According to the water seal tank, a working gas condensate outlet and the overflow opening are integrated, process equipment and process piping are simplified, process requirements can be completely met, the construction difficulty is reduced, and the engineering investment is reduced.

Description

technical field [0001] The invention relates to the technical field of chemical equipment, in particular to a negative pressure water seal tank. Background technique [0002] In the chemical process, the water seal tank refers to the equipment used to ensure the pressure of the sealed gas and separate the gas and liquid of the sealed gas. It is a safety facility for isolating volatile, toxic and harmful gases from the atmosphere. It can effectively reduce the Gas volatilization will pollute the environment and ensure the stable operation of the device. [0003] Chemical equipment exists on the basis of chemical technology and serves the chemical process. In the traditional chemical process flow, the negative pressure water seal tank is separately provided with the working gas condensate outlet and overflow port, and the working gas condensate outlet is located at the bottom of the equipment, so the equipment needs to be placed in the frame, and in the middle of the equipmen...

AI Technical Summary

Problems solved by technology

In the traditional chemical process flow, the negative pressure water seal tank is separately provided with the working gas condensate outlet and overflow port, and the working gas condensate outlet is located at the bottom of the equipment, so the equipment needs to be placed in the frame, and in the middle of the equipment foundation needs reserved holes (see attached figure 1 And attached figure 2 ), the project investment is high, and the construction difficulty increases
