Pressure swing adsorption nitrogen-making device with centralized pollution discharge function

Abstract

The invention discloses a pressure swing adsorption nitrogen-making device with a centralized pollution discharge function, which comprises a protection box, a first gas storage mechanism is arranged on the right side of the protection box, the first gas storage mechanism is composed of a first connecting pipe, a first gas storage tank and a second connecting pipe, one end of the first connecting pipe is fixedly communicated with the first gas storage tank, the other end of the first connecting pipe extends into the protection box and is fixedly communicated with an air compressor, an air inlet mechanism is arranged on the left side face of the protection box, the air inlet mechanism is composed of an air inlet pipe, a partition plate, air inlet holes and two first limiting frames, and a filtering mechanism is arranged on the left side face of the air inlet pipe. A second electromagnetic valve is opened while a first electromagnetic valve is closed, and at the moment, high-pressure airflow conveyed by a fourth connecting pipe sprays substances in a filter screen cylinder out of a blow-off pipe, so that concentrated discharge of the substances in the filter screen cylinder is realized, and the situation that use of the nitrogen-making device is affected due to excessive dirt on the filter screen cylinder can be reduced; the practicability of the nitrogen-making device is improved.

Description

technical field [0001] The invention relates to a nitrogen production device, in particular to a pressure swing adsorption nitrogen production device with centralized sewage discharge function. Background technique [0002] Nitrogen, chemical formula N 2 , is a colorless and odorless gas. The chemical properties of nitrogen are very inactive. It can react with hydrogen to form ammonia under high temperature, high pressure and catalyst conditions; it can combine with oxygen to form nitric oxide under the condition of discharge, even Ca, Mg, Sr Active metals such as Ba and Ba can only react with it when heated. The high chemical stability of nitrogen is related to its molecular structure. [0003] The pressure swing adsorption nitrogen generator is a common nitrogen generator. During the nitrogen production process, the filtered air needs to be passed into the nitrogen generator. The air filter in the nitrogen generator will generate dirt when it is used. Now The air filter ...

Problems solved by technology

[0003] The pressure swing adsorption nitrogen production device is a common nitrogen production device. During the production process of nitrogen, the filtered air needs to be passed into the nitrogen production machine. The air filter in the nitrogen generating device is not convenient for centralized discharge of pollutants, which affects the use of the nitrogen generating device
