Problems solved by technology

The device has a good dust removal effect, but it needs an air compressor for producing high-pressure gas; although the device has a slag filter layer, it cannot completely separate the precipitated dirt, and it is difficult to recycle both waste water and sediment, which also leads to high operating costs

Embodiment Construction

[0009] An air purification device, a calcium oxide powder funnel 9 for desulfurization is installed on the flue 13, and a powder nozzle 10 extending into the flue is arranged at the lower end of the funnel. The nozzle is automatically controlled by a computer. How much, automatically control the injection amount of calcium oxide powder. When working, the sulfur substances in the flue gas react chemically with the calcium oxide powder, that is, CaO+S→CaSO 3 , so that the sulfur solidifies into small particles and enters the flue gas.

[0010] Washing tub 3 is 1700mm long and 1300mm in diameter, and its lining surface adopts anti-corrosion layer 2. The diameter of hollow shaft 4 is 85mm. The right end and water supply pipe 7 are connected in a flexible seal. The diameters of the cylindrical water nozzles 6 and 6' are 2mm, and the cylindrical water nozzles 6 and the circular hole water nozzles 6' are distributed at intervals. Washing drum motor 23 is 7.5kw, and the rotating sp...

Abstract

The fume purifier has pipeline with computer controlled desulfurizing powder nozzle; hollow washing barrel shaft with spiral blades and water nozzles; flocculating tank with flocculant inlet, stirrer and solenoid valve; and screen filter in the inclination angle of 0-8 deg. During its operation, SO2 is solidified chemically to form grains entering the fume, the fume is sucked into the washing barrel and washed with water from the hollow shaft, the sewage is deposited in the flocculating tank and filtered to separate pollutant from water, and the pollutant and the clear water are reused. The present invention has high dedusting and desulfurizing effect, and low cost.

Description

Technical field [0001] The invention relates to the fields of gas purification and fluid filtration, especially a flue gas purification device. technical background [0002] Smoke pollutes the atmosphere. People have had many solutions for many years, but they are common or the technology is complex, expensive, or the effect is not satisfactory. The Chinese patent notification number is CN2038200u, which discloses "Rotary Water Spray Type Smoke Elimination and Dust Removal Device". There is a rotating hollow shaft in the cylinder of the device, with fan blades and water spray nozzles on the shaft, and the flue gas is sucked into the cylinder to carry out wet dust removal. Although the dust removal efficiency of this device is very good, it has to be maintained with a large amount of water consumption, too much sewage is generated, and the sewage pool occupies an excessively large area, resulting in high operating costs. The Chinese patent notification number is CN2294769y, ...
