Description

Technical Field

[0001] The utility model relates to a tail gas treatment liquid recovery and treatment device. Background Art

[0002] With the rapid development of the automobile industry and the continuous improvement of the economic level, the number of cars in my country is increasing year by year, and the automotive aftermarket is also in a stage of gradual and stable development. Because motor vehicle exhaust contains nitrogen oxides, if it is not discharged without treatment, it will cause serious harm to the environment. Therefore, it is very necessary to remove nitrogen oxides before exhaust emission.

[0003] In addition, a large amount of tail gas will also be discharged during the chemical reaction, which contains a large amount of sulfide, nitride and other toxic components. Some of the existing tail gas is directly discharged into the air, and some is discharged after simple treatment. In any case, the tail gas discharged into the air contains untreated harmful components, which will cause serious damage to the environment.

[0004] Basically, enterprises adopt a simple circulating spraying method for removal and purification. In some existing tail gas treatment devices, the treatment liquid cannot be effectively separated from the gas when the gas is discharged, which causes the treatment liquid to be lost too quickly, increasing costs, and the treatment liquid cannot be recycled and reused. In view of this, this invention is specially applied for. Utility Model Content

[0012] The utility model has a novel design and is provided with a reactor, a support frame, an air intake pipe, an exhaust pipe and a processing box. In particular, a booster nozzle is arranged in the air intake pipe to accelerate the pressurization of the exhaust gas into the reactor. At the same time, after the rising treatment liquid is adsorbed by the tail gas, a part of the mist with the treatment liquid will fall back on the bottom surface of the reactor through the contact with the condensation plate. At the same time, a nozzle is arranged in the inner cavity of the reactor. The treatment liquid in the nozzle is lifted by the water pump on the processing box. The treatment liquid forms a mist and fully contacts with the tail gas entering from the air intake pipe. Due to the existence of the baffle cover, the gas-liquid separation rate can be slowed down, and the blocked mist will fall into the reactor. The designed reflux pipe can realize the recovery of the treatment liquid. BRIEF DESCRIPTION OF THE DRAWINGS
