A RTO special valve for regenerative oxidation furnace

Abstract

The invention discloses a special valve for a regenerative thermal oxidizer (RTO). The special valve comprises a valve body mechanism, a rotary valve element mechanism, a sealing mechanism and a switch control mechanism, wherein the valve body mechanism is composed of a valve body, a gas outlet connecting pipe and two core shaft mounting frames; the valve body is in a cylinder shape; one end of the valve body is a gas inlet; a gas outlet is formed in the valve body; the gas outlet connecting pipe is arranged on the gas outlet; the rotary valve element mechanism is composed of a valve element, a core shaft and two fixing connecting frames; the valve element is in the cylinder shape and installed in the valve body; the core shaft is installed in the valve element, fixedly connected with the valve element through the fixing connecting frames and rotationally installed on the core shaft mounting frames in the valve body; the core shaft, the valve element and the valve body are coaxially arranged; an air vent is formed in the valve element and matched with the air outlet in a communicating or isolating manner; the sealing mechanism is arranged on the gas outlet connecting pipe and is in sealed connection to the gas outlet connecting pipe and the valve element; the switch control mechanism is composed of a switch drive mechanism and a transmission shaft; and the transmission shaft is in transmission connection with the core shaft and the switch drive mechanism.

Description

technical field [0001] The invention relates to a special component for a regenerative oxidation furnace RTO, more specifically, the invention relates to a special valve for a regenerative oxidation furnace RTO. Background technique [0002] Regenerative Thermal Oxidizer (RTO) is a special equipment that can efficiently purify organic waste gas. [0003] The working principle of the regenerative oxidation furnace RTO is: in a high-temperature environment (generally between 750 and 850 degrees Celsius), volatile organic compounds (hydrocarbons) in the organic waste gas undergo oxidation reactions with oxygen in the air to generate carbon dioxide and water, thereby purifying organic waste gas. [0004] The existing regenerative oxidation furnace RTO generally includes a combustion chamber, a burner and a ceramic regenerator bed. The air inlet and exhaust port of the above combustion chamber are respectively equipped with special valves for the regenerative oxidation furnace R...

AI Technical Summary

Problems solved by technology

At the same time, since the regenerative oxidation furnace RTO purifies organic waste gas, and the organic waste gas contains volatile organic compounds, if the regenerative oxidation furnace RTO leaks, it will cause serious pollution to the environment. Therefore, the regenerative oxidation furnace Oxidation furnace RTO has very high requirements on the sealing performance of its special valves, and basically zero leakage is required
