Dust removing and cooling device of high-temperature flue gas

Abstract

The invention relates to the technical field of flue gas treatment and particularly discloses a dust removing and cooling device of high-temperature flue gas. The dust removing and cooling device comprises a dust removing and cooling mechanism and a receiving mechanism, wherein the dust removing and cooling mechanism comprises a shell and a rotary shaft; dust removing blades are arranged on the rotary shaft; an air inlet pipeline is arranged at the upper part of the shell, a one-way rotary air inlet valve is arranged at the middle part of the air inlet pipeline, and the upper end of the rotaryshaft penetrates through the upper part of the shell and is connected with the one-way rotary air inlet valve by threads; a blocking part is arranged at the lower part of the shell and is provided with a through hole, and a matching part is arranged at the lower end of the blocking part and is provided with an air outlet; and the receiving mechanism is positioned at the lower end of the matchingpart and comprises a receiving pool and a cross shaft, a blade group is arranged on the cross shaft, a worm wheel and worm structure is arranged at the middle part of the cross shaft, the rotary shaftis connected with a worm wheel, a water outlet is formed in the receiving pool, and a water inlet pipe is connected between the water outlet and the rotary shaft. According to the dust removing and cooling device disclosed by the invention, the problem that flying smoke dust is very difficult to collect due to lower adsorbability for smoke dust in the gas in the cooling process is solved; in addition, cooling water can be recycled, so that the water resource is saved.

Description

technical field [0001] The invention relates to the technical field of flue gas treatment, and specifically discloses a high-temperature flue gas dust removal and cooling device. Background technique [0002] In the industrial production process of metallurgy, cement, electric power, chemical industry, machinery manufacturing, etc., a large amount of high-temperature flue gas will be emitted. High-temperature flue gas has the characteristics of high temperature, complex composition, large amount of flue gas, and large amount of dust. Random discharge will not only cause air pollution, but also the high-temperature flue gas produced by certain processes is flammable and explosive, which will endanger urban safety. [0003] In recent years, the treatment and purification of high-temperature flue gas has attracted more and more attention. The purification process is mainly to remove dust particles in high-temperature flue gas. The temperature resistance requirements of the hig...
