The invention relates to the technical field of tail gas treatment devices, in particular to a paraformaldehyde production tail gas treatment device. In the prior art, paraformaldehyde generates a large amount of waste gas and dust in a powder grinding stage. The surrounding air is polluted. The device comprises a rake dryer, a material conveying machine, a material grinding barrel and a sprayingtower, wherein a material conveying machine is arranged at a discharge hole of the rake dryer; a conveying motor is mounted on one side of the material conveying machine; a grinding barrel is mountedat the tail end of the conveying machine; and a grinding motor and a first exhaust fan are fixed to the top of the grinding barrel through bolts. According to the tail gas treatment device for paraformaldehyde production, the rake dryer, the material conveying machine, the material grinding barrel and the spraying tower are cooperated, so that drying, sealed conveying, powder grinding and tail gas treatment functions are completed, and dust and waste gas generated in the powder grinding process are effectively purified and collected, therefore, the problem that the surrounding environment ispolluted is effectively solved, the body health of operators is guaranteed, and practicability is high.
Description
technical field [0001] The invention relates to the technical field of tail gas treatment devices, in particular to a tail gas treatment device for paraformaldehyde production. Background technique [0002] Paraformaldehyde with a low degree of polymerization can replace ordinary industrial formaldehyde aqueous solution, and it can not only reduce the energy consumption of dehydration, but also greatly reduce the waste water treatment in various downstream products of formaldehyde such as synthetic pesticides, synthetic resins, paints and fumigation disinfectants. This is a green environmental protection project that benefits the country and the people. Paraformaldehyde with a low degree of polymerization has a higher active ingredient than industrial formaldehyde, and is a solid particle, which is beneficial to the chemical synthesis of chemical industry, pharmaceuticals and other industrial fields, especially in the synthesis that requires the use of anhydrous formaldehyde...
