Organic waste gas treatment integrated equipment

Abstract

The invention relates to the field of waste gas treatment, in particular to organic waste gas treatment integrated equipment which comprises a pretreatment filter, an RTO thermal storage and burning furnace body, and an air volume control system for controlling the discharging amount of organic waste gas, and further comprises a pressure release safety device arranged on the RTO thermal storage and burning furnace body; after passing the pretreatment filter, organic waste gas enters the RTO thermal storage and burning furnace body under control of the air volume control system; and a pressuredifference transmitter for monitoring the pressure difference of the two sides of the RTO thermal storage and burning furnace body is arranged on the RTO thermal storage and burning furnace body and is connected with the air volume control system. According to the organic waste gas treatment integrated equipment, the pressure difference transmitter can compare the pressure difference between an air intake pipeline and an air discharging pipeline to control the blast amount of the air volume control system and realize the purposes of energy conservation and consumption reduction; and after reaching the set pressure value, the pressure release safety device blasts for decompression, the RTO thermal storage and burning furnace body is prevented from being damaged due to excessively large pressure during the operating process.

Description

technical field [0001] The invention relates to the field of waste gas treatment, and more specifically, relates to an integrated device for treating organic waste gas. Background technique [0002] With the rapid development of my country's economy, the environmental problems are becoming more and more serious, especially in terms of VOCs governance. New standards are frequently issued in various places and industries, and the engineering governance of VOCs in various industries is continuously strengthened, and the emission standards are becoming more and more stringent. [0003] In many industrial enterprises, there are a variety of organic waste gas emission characteristics, such as: large air volume and low concentration, small and medium air volume, high concentration, large concentration fluctuations, and many impurities. The front-end collection system of the treatment facilities has not been rationally designed, resulting in the fan still running at high power when ...

Problems solved by technology

[0003] In many industrial enterprises, there are a variety of organic waste gas emission characteristics, such as: large air volume and low concentration, small and medium air volume, high concentration, large concentration fluctuations, and many impurities. The front-end collection system of the treatment facilities has not been rationally designed, resulting in the fan still running at high power when the air volume is small, resulting in energy waste. In addition, at present, for the treatment of organic waste gas with small and medium air volume, RTO thermal storage combustion is generally used for treatment , the principle is to oxidize the organic matter (VOCs) in the organic waste gas into the corresponding carbon dioxide and water at high temperature, thereby purifying the organic waste gas and recovering the heat released when the waste gas is decomposed. However, the current RTO regenerative combustion furnace body , the temperature in the furnace body is generally difficult to control. When the furnace temperature is too high, it is prone to fry the furnace. Therefore, some RTO regenerative combustion furnaces are equipped with bursting discs. The setting of the bursting discs can ensure that the RTO heat storage in an emergency The combustion furnace has the greatest safety factor to prevent damage to the equipment. However, the structure of the bursting discs on the market is relatively simple, and the function is relatively single, which does not meet the current needs of people.
