RTO external switching valve bank for chemical corrosive waste gas

Abstract

The invention discloses an RTO external switching valve bank for chemical corrosive waste gas, and belongs to the technical field of heat accumulating type incinerators. The RTO external switching valve bank comprises an air distribution chamber, and the two sides of the air distribution chamber communicate with valve bodies through communicating outer pipes and clamping mechanisms; and the bottoms of side valve bodies on the two sides are movably connected with a smoke exhaust pipeline and a waste gas inlet pipeline through clamping mechanisms correspondingly, and the outer wall of the clamping mechanism on the top is sleeved with a protection mechanism. According to the RTO external switching valve bank for chemical corrosive waste gas, the shutdown time caused by maintenance work is greatly shortened, and even an emergency purification facility is configured for maintenance work in a short time, so that the situation of shutdown caused by maintenance can be avoided, and for the working condition that general production of chemical enterprises is 24-hour continuous operation and severe conditions of corrosive gas and crystallization blockage, by using the independent external switching valve body specially designed for chemical enterprises, the risks of long maintenance period and operation safety of maintenance personnel can be effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of regenerative incinerators, and in particular relates to an RTO external switching valve group for chemical corrosive waste gas. Background technique [0002] The regenerative incinerator is a way to incinerate organic waste gas at high temperature. It raises the temperature of the organic waste gas discharged from the production process to 760-950°C, and directly oxidizes and decomposes it into CO2 and H2O at this high temperature. The high temperature during oxidation The heat of the gas is "stored" by the ceramic regenerator, which is used to preheat the newly incoming organic waste gas, thereby saving the fuel consumption required for heating up. There are 3 groups of 6 sets of airflow switching valves arranged symmetrically on both sides of the bottom of the regenerative type. , 3 sets of switching valves correspond to the three regenerators of the RTO, which are opened and closed in a certain order t...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is: in order to solve the problem that once the switching valve fails, the maintenance is difficult, the maintenance cycle is long, and the waste gas discharged from the production process of the chemical industry contains corrosive gas, which leads to the reduction of the life of the switching valve body.
