Flue gas denitration multi-pollutant cooperative treatment equipment and use method thereof

Abstract

The invention discloses flue gas denitration multi-pollutant cooperative treatment equipment. The equipment comprises a working box and a discharging bin, a water tank is fixedly arranged on the sidewall of one side of the working box, a water inlet pipe is arranged at one end of the water tank, a plurality of cooling pipes are arranged at the top of the water tank, impurities in the flue gas cannot enter an SCR denitration reactor, the impurities fall into the discharging bin and then are accumulated on a material sealing plate through the discharging bin, after denitration is completed, a hydraulic cylinder controls the outer side of a piston rod cylinder body in the hydraulic cylinder to move, a piston rod pushes a hook plate to rotate, so that a rotation shaft rotates, then, a material sealing plate rotates, impurities on the material sealing plate fall into a material receiving box, after the material receiving box is full of the collected impurities, the material sealing plate is closed, buckles are opened, the side wall of the material receiving box is pushed, and the material receiving box is moved out from the lower portion of a discharging pipe through rollers, so that workers can conveniently conduct unified treatment on the impurities, meanwhile, the equipment is guaranteed to continuously conduct purification work, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the field of sintering machine flue gas purification equipment, in particular to a flue gas denitrification and multi-pollutant collaborative treatment equipment and a use method thereof. Background technique [0002] The sintering machine is suitable for the sintering operation of large-scale ferrous metallurgical sintering plants, and is mainly suitable for the sintering treatment of iron ore powder in large and medium-sized sintering plants. When the sintering machine is in use, it will produce a large amount of harmful fumes, which need to be purified. The present invention proposes to pass the sintering flue gas through the electric precipitator, pass through the sintering main exhaust fan, and then enter the SDA desulfurization tower for desulfurization. The temperature of the gas is raised, and then the flue gas is further heated to the denitrification reaction temperature through the supplementary combustion device, an...

Problems solved by technology

[0004] The purpose of the present invention is to provide a flue gas denitrification multi-pollutant cooperative treatment equipment and its use method to solve the problem of de-stocking the flue gas through the SCR denitrification reactor during the use of the existing sintering machine flue gas denitrification device. The heat exchanger does not have a conical plate structure, the water after heat exchange cannot enter the outside of the conical plate, and the water easily enters the SCR denitration reactor, which affects the use of the SCR denitration reactor and is not convenient for subsequent cooling treatment ; During the use of the existing sintering machine flue gas denitration device, the purified gas has high heat, which cannot realize energy recycling; Difficult. After the receiving box is full of impurities, it is necessary to stop the device and perform purification work after processing the receiving box, which affects work efficiency.
