The embodiment of the invention discloses a desulfurization and denitrification clean discharge system for low-temperature waste gas. The system comprises a heat exchange mechanism, a desulfurizationtower mechanism, a reaction liquid circulating device, a heating device, a denitration device and a chimney which are sequentially connected through a pipeline. A circulating waste gas frame, a wastegas guide ring, a spraying device, a demister and an air exhaust mechanism are sequentially arranged in the desulfurization tower mechanism from bottom to top. Waste gas is discharged into the desulfurization tower mechanism through the waste gas guide ring, and reaction liquid is sprayed through the spraying device to desulfurize the waste gas. The input waste gas is guided by the waste gas guidering arranged in the desulfurization tower to be spirally sprayed, and with the increase of the internal pressure of the desulfurization tower mechanism, the cyclone formed by the waste gas continuously moves towards an output port above, and the spiral waste gas cyclone can drive the atomized reaction liquid sprayed by the spraying device to move along with the cyclone direction, so that the contact time of the reaction liquid and the waste gas is prolonged, and the desulfurization effect of the waste gas is improved.
Description
technical field [0001] The embodiments of the present invention relate to the technical field of waste gas treatment, and in particular to a desulfurization and denitrification clean emission system for low-temperature waste gas. Background technique [0002] As air pollution continues to increase, desulfurization and denitrification technology is being paid more and more attention by various countries. Flue gas desulfurization and denitrification technology is a boiler flue gas purification technology applied to the chemical industry where many nitrogen oxides and sulfur oxides are generated. The existing flue gas Most of the desulfurization and denitrification process adopts the process of desulfurization first and then denitrification, and the exhaust gas after desulfurization and denitrification is discharged to high altitude through the chimney. [0003] In the prior art, the conventional desulfurization device is a desulfurization tower, through which the low-temperatu...
