White smoke eliminating and purification integrated device

Abstract

The invention relates to a white smoke eliminating and purification integrated device. The white smoke eliminating and purification integrated device comprises a gas inlet pipeline, the gas inlet pipeline is communicated with a flue gas warming device, the flue gas warming device is communicated with a purification device, and the purification device is communicated with a flue gas discharge pipe.The flue gas warming device comprises a shell, an inner cavity of the shell is provided with multiple heat exchange pipes, one ends of the heat exchange pipes are communicated with the gas inlet pipeline, the other ends of the heat exchange pipes are communicated with the purification device, and a heat exchange space is formed between the inner wall of the shell and the outer walls of the heat exchange pipes and communicated with the flue gas discharge pipe. By means of the flue gas warming device, high-temperature flue gas in the gas inlet pipeline and low-temperature flue gas in the flue gas discharge pipe can conduct heat exchange to increase the discharge temperature of the flue gas and decrease the temperature of the flue gas entering the purification device. By means of the white smoke eliminating and purification integrated device, the defect that existing flue gas cannot be subjected to purification and white smoke eliminating in one system can be overcome, and the efficiencyof purification and dewatering the flue gas is improved.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to an integrated whitening and purification device. Background technique [0002] With the upgrading of the national environmental protection policy and regulatory system, various departments have put the purification and elimination of colored plume on the agenda, and promoted and implemented it nationwide. [0003] The inventor believes that the most effective way to eliminate the colored plume is to cool down and condense before heating up to discharge. However, in general processes, medium heating is used to heat up the flue gas before discharge, which consumes a lot of energy. In addition, for dust and other pollutants The treatment of the colored plume needs to purify the flue gas on the basis of whitening, which does not have this function in the general whitening process. Especially for the treatment of hot stuffy steam of steel slag and the whi...

[0003] The inventor believes that the most effective way to eliminate the colored plume is to cool down and condense before heating up to discharge. However, in general processes, medium heating is used to heat up the flue gas before discharge, which consumes a lot of energy. In addition, for dust and other pollutants The treatment of the colored plume needs to purify the flue gas on the basis of whitening, which does not have this function in the general whitening process

Especially for the treatment of hot and stuffy steam of steel slag and the whitening and purification treatment of wet quenching steam, there is no suitable treatment process at present, and it has been in the way of simple collection and direct discharge, causing serious pollution
