Device for purifying toxic gas in production of chemical products for chemical machinery

Abstract

The invention relates to a device for purifying toxic gas in the production of chemical products for chemical machinery. The device for purifying toxic gas comprises a supporting seat, a sealing mat and a backflow hose, wherein a sliding chute is fixed to the inner side of the top of the supporting seat; a sliding block is installed on the inner side of the sliding chute; a first water tank is connected to the top end of the sliding block; an air vent pipe is installed on the right side of the first water tank; a first connection pipe is arranged at the left end of the first water tank. The device has the beneficial effects that the first water tank, a second water tank, a third connection pipe and a second permeable membrane are arranged; the inner wall of the third connection pipe is attached to the outer side of the second permeable membrane; when the chemical machinery is performing chemical product production work, the toxic gas generated in the working process of the chemical machinery permeates through the second permeable membrane along the third connection pipe to enter the second water tank and be subjected to a chemical neutralizing reaction through abutting of the thirdconnection pipe and the chemical machinery, and one-time purifying work on the toxic gas can be conveniently completed by the device.

Description

technical field [0001] The invention relates to the technical field of chemical machinery production gas purification, in particular to a toxic gas purification device for chemical machinery used in the production of chemical products. Background technique [0002] Chemical machinery and equipment is the general term for machines and equipment used in chemical industrial production. In order to process raw materials into finished products of a certain specification in chemical production, it often needs to go through a series of chemical processes such as raw material pretreatment, chemical reaction, and separation and purification of reaction products. , The machinery used to realize these processes is often classified as chemical machinery, and when chemical machinery produces chemical products, it is easy to generate toxic gases, so that the staff need to purify them through toxic gas purification devices. [0003] In the process of using the existing gas purification dev...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a toxic gas purification device for chemical machinery used in the production of chemical products, to solve the problem that the existing gas purification device proposed in the background technology has simple and convenient steps during use, and it is difficult to thoroughly purify the toxic gas. , so that toxic gases are discharged into the air, causing serious air pollution, and the flexibility of the device is not strong, which increases the limitations of the device's work and affects the working performance of the device
