Technical Field

The utility model relates to the technical field of waste gas treatment, in particular to an improved device which can reduce the operating cost of RTO waste gas.

Background Art

The regenerative heat incinerator (RTO incinerator) is mainly composed of a regenerative chamber, an oxidation combustion chamber, a switching valve, a burner, a gas and combustion-supporting system, a compressed air system, a control system, etc. The operation of each part is interlocked and stable.

According to the Chinese patent application number (patent number 202020901339.X), a low-temperature sintering furnace is disclosed. It adopts a series of structures such as a gas filtration device and a drying box to effectively remove organic solvents and irritating gases generated during the sintering process, thereby achieving the effect of protecting the environment.

However, during use, a large amount of heat from the irritating gases generated in the sintering furnace is absorbed by the filter water tank. The increase in temperature causes further volatilization of the organic solvent in the filter water tank, making it difficult to remove the organic solvent. In addition, the contact time between the organic solvent and water in the filter water tank is short, making it difficult to fully dissolve in the water, resulting in incomplete removal of the organic solvent. In addition, the airflow generated during the pumping process of the exhaust gas is easily wasted. To this end, we provide an improved equipment that can reduce the operating cost of RTO exhaust gas to solve the above problems.

The connecting pipe 303 is made of stainless steel.

The air introduced into the purification box 301 through the connecting pipe 303 carries a large amount of heat, which heats the air inside the purification box 301, thereby removing water vapor contained in the air, achieving the effect of waste heat recovery and further utilization of resources.

Furthermore, the lower section of the connecting pipe 303 embedded in the purification box 301 is horizontally arranged, the horizontal part of the connecting pipe 303 is immersed in the clean water, and a plurality of through holes with a diameter of 1 mm are opened at the top of the lower horizontal part of the connecting pipe 303;
