Automatic water supplement device for coal gas purification system and control method of device

Abstract

The invention discloses an automatic water supplement device for a coal gas purification system. The coal gas purification system is provided with an underground groove and a pump, one end of a waterpumping pipe extends into the underground groove, and the other end of the water pumping pipe is connected with a water inlet of the pump; a water outlet of the pump is connected with a water outlet pipe, the device is provided with a water supplement groove, and the bottom of the water supplement groove is connected with a pump priming port of the pump through a pipe; the height of the bottom ofthe water supplement groove is higher than that of the pump priming port, and a first valve is arranged on the pipe. According to the automatic water supplement device, automatic water supplement andliquid level linkage of storage grooves for the coal gas purification system are achieved, the pump is automatically started and stopped, and the labor intensity of workers and hidden dangers of environmental protection accidents are reduced.

Description

Technical field [0001] The invention relates to the field of industrial automation. Background technique [0002] The gas purification system has multiple underground tanks and accident tanks, equipped with centrifugal pumps to transport materials. Each time the pump is turned on, the pump needs to be filled manually before the pump runs normally; the pump stops after the liquid level is manually confirmed, which wastes human resources, and Under special circumstances, the liquid level rises rapidly, which can easily overflow the tank and cause environmental accidents. Summary of the invention [0003] The technical problem to be solved by the present invention is to realize an automatic water replenishing device for the gas purification system and the liquid level interlocking of the storage tank, realize the automatic start and stop of the pump, and reduce the labor intensity of employees and reduce the hidden danger of environmental protection accidents. [0004] In order to ach...

Problems solved by technology

[0002] The gas purification system has multiple underground tanks and emergency tanks, and is equipped with a centrifugal pump to transport the material. Before starting the pump, it needs to be filled manually so that the pump can run normally; stopping the pump after manually confirming the liquid level is a waste of human resources, and Under special circumstances, the liquid level rises rapidly, and it is easy to flood the tank, causing environmental accidents
