Venturi tube dust: the diversion device (nebulizer), Venturi tube and a dehydrator. Principle and the advantages and disadvantages of ESP: ESP is the use of electricity generated by the electrostatic field so that the dust particles separated from the gas stream device. Advantages: Suitable for particulate control, 1 ~ 2μm particle size of dust removal plant efficiency up to 98% to 99%, the lower the resistance of the electrostatic precipitator dust engineering factory in Hangzhou, only 100 ~ 200Pa, can handle high temperatures ( 400 ℃ or less) of gas, for large projects, the greater the amount of gas treatment plant dust fan, its economic effect is more obvious. Disadvantages: large equipment, large area, more consumption of steel, a large investment. More complex structure, manufacture, installation of high precision, the specific resistance of the dust has certain requirements. ESP power supply device, comprising: a step-up transformer, rectifier, control devices. Design requirements: ⑴ before the end of the suction inlet jet must average speed v is determined according to the bath temperature: air flow velocity on the suction outlet ⑵ v≤ (2 ~ 3) the amount of exhaust v'⑶ suction outlet should be greater than before the jet suction outlet flow is the end of the jet flow of 1.1 to 1.25 times the height of the air outlet ⑷ generally 0.010 ~ 0.015H, in order to prevent the occurrence of clogging of the air outlet, air outlet height should be greater than 5.0 ~ 7.0mm. Hair Exit flow rate should not exceed 10 ~ 12m / s, in order to avoid level fluctuation.
