Gas scrubbers for gas generators

Abstract

A gas-washing device for a gas producer comprises a gas-washing box; a distributor is disposed at a coal gas inlet of the gas-washing box; a coal gas inlet pipe is connected with the upper end of the distributor; the invention is characterized in that: the distributor comprises a distributor body and a reinforcing rib plate; the distributor body is a cylinder; at least two separating ribs are disposed on the inner wall of the cylinder and are arranged staggeredly as a matrix in the cross section of the cylinder; the separating ribs divides the cylinder cavity into at least four identical sector gas-introducing channels; the reinforcing rib plate comprises a round center plate and bar-shaped plates uniformly and divergently distributed at the periphery of the center plate; the reinforcing rib plate is fixed above the inner wall of the distributor body and the separating ribs; the size of the reinforcing rib plate fits the inner wall of the cylindrical cylinder body. The gas-washing device for a gas producer of the invention is washing resistant, has a long life, and has uniform gas flow distribution.

Description

technical field [0001] The invention relates to a gas scrubber, in particular to a gas scrubber for a gas generator. Background technique [0002] The gas washing device used in the gas generator system includes a gas washing box, which is also known as a water seal tank. Its main function is to prevent the gas in the system main pipe from being poured back into the gas furnace system when the gas furnace is shut down, and at the same time initially wash the gas , Dust removal and cooling, a distributor is installed at the gas inlet of the gas scrubber, the lower end of the distributor is immersed in the water surface of the gas scrubber, and the upper end is connected to the intake pipe with a 90° elbow, the gas passes through the distributor and then goes up the distributor. Each hole enters the water tank and then emerges from the water, and is led out by the gas outlet pipe on the top of the scrubber box. As the working time of the gas furnace increases, the gas flow wi...

AI Technical Summary

Problems solved by technology

As the working time of the gas furnace increases, the gas flow will cause more and more harm to the distributor of the gas scrubber: the main air flow is directly in front of the elbow of the inlet of the gas scrubber, and the corresponding distributor rib is less than one The overhaul cycle is washed out, resulting in the failure of the water seal, causing the gas furnace to stop ash for a short time every day, and the gas furnace mouth fires during cleaning and maintenance, which affects safe production

The air flow behind the elbow is small and easy to block. After a long time, only one or two holes directly in front pass through the gas, and the gas flow rate into the gas scrubber is greatly accelerated, making the water surface of the gas scrubber boil, and the gas outlet is heavily watered.

When the situation is particularly serious, the ports of the distributor are basically blocked, the system pressure is high, and the gas cannot be sent out, which is likely to cause safety accidents
