Novel VOCs disposal device based on RTO and RCO cooperative work, and working method thereof

Abstract

The invention relates to a novel VOCs disposal device based on RTO and RCO cooperative work. The novel VOCs disposal device comprises a tower body which is internally provided with a first tower chamber, a second tower chamber, a third tower chamber and a combustion chamber, and the tower chambers are connected with the combustion chamber separately; and the combustion chamber is provided with a burner. Intake valves and outtake valves are arranged below the tower chambers. According to a working method of the VOCs disposal device, the novel VOCs disposal device according to any one of 1-6 claims is used; according to the following three modes, the cycle working is performed in the mode I, the mode II and the mode III. The novel VOCs disposal device has the advantages of the simple structure, low fault rate, small occupied area and higher heat utilization rate, and disposal of organic waste gas can be finished effectively.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a novel VOCs disposal device based on the cooperative work of RTO and RCO and a working method thereof. Background technique [0002] In today's society, the pollution of waste gas is serious, and the effective treatment of volatile organic waste gas has become the top priority of the environmental protection industry. As one of the important means of treating organic waste gas, the incineration method has high treatment efficiency, but low operational safety and high technical requirements. Therefore, how to maintain the advantages and improve to overcome the disadvantages is something we need to discuss in depth. [0003] RTO (Regenerative Thermal Oxidizer) is a high-efficiency organic waste gas (VOC) treatment equipment. Compared with the traditional catalytic combustion and direct-fired thermal oxidizer (TO), it has high thermal efficiency (≥95%) and operating cost. I...

AI Technical Summary

Problems solved by technology

[0004] RTO (Regenerative Thermal Oxidation Oxidation Oven) has an interlock to cut off the intake of organic waste gas and then directly empties it from the bypass. The high-temperature exhaust gas is directly mixed with high-concentration organic waste gas, causing the exhaust pipe to explode. At the same time, the concentration of organic waste gas and the amount of waste gas will decrease. There are intermittent changes, and generally the capacity of the buffer tank is small, which often leads to unstable operation of the RTO

[0005] RCO (Regenerative Catalytic Combustion Oven) treatment of VOCs will cause direct radiation from the flame at the burner to the catalyst, which will cause the catalyst to be easily over-temperature poisoned and fail.

Or when there are harmful gases in the exhaust gas, the heavy catalyst will be poisoned, the catalyst will lose its activity and cannot work, resulting in an increase in VOCs emissions
