This application is through making up cyclone and electrostatic precipitator in order to form compound separator, the air current can pass through cyclone and the twice dust removal flow of electrostatic precipitator, the dust removal effect has been improved, simultaneously, through 5 intercommunications communicating pipes between air intake 33 and the electrostatic precipitator 4, make the tiny particle in the electrostatic precipitator 4 combine into behind the bigger granule by electrostatic interaction mutual adsorption, accessible communicating pipe 5 gets into air intake 33 department, and separate in getting into barrel 1 once more, finally fall into unloading valve 2 in, with this, can avoid the particulate matter in the electrostatic precipitator 4 to pile up, influence dust removal effect, the unified collection of the follow-up particulate matter of also being convenient for simultaneously handles.

It should be noted that the ash discharge valve 2 is specifically an electric ash discharge valve, and the electric ash discharge valve 2 is generally composed of a rotor impeller with a plurality of blades, a casing, a speed reducer and a motor by adopting the prior art, is mainly installed in an ash hopper of a dust remover for discharging ash, and can also be widely used for a discharge device of a feeding and ash discharge system in the industries of chemical industry, metallurgy, mine, machinery, electric power, grain and the like. The use principle is as follows: the rotor with a plurality of blades is driven by the motor to rotate in the shell, and materials falling from the hopper at the upper part are filled in gaps between two adjacent blades and are discharged along with the rotation of the blades.

The air inlet pipe 32 is tangential to the outer side wall of the conversion chamber 31. So that when the dusty gas flow enters the conversion cavity 31 from the gas inlet pipe 32, the gas flow changes from linear motion to circular motion, so that the dusty gas flow can spirally enter the cylinder 1.

It generally consists of two parts: one part is an electrostatic dust collector body system, and the other part is a power supply device for providing high-voltage direct current and a low-voltage automatic control system. The working principle is as follows: when the dust-containing airflow passes through the high-voltage electrostatic field, the airflow is electrically separated, and dust particles and negative ions are combined to be charged negatively and then tend to discharge on the surface of the anode to be deposited. The method is a dust collecting method which uses an electrostatic field to ionize gas so as to enable dust particles to be adsorbed on an electrode in an electrified way. The principle of operation, manner of use and construction are well known to those skilled in the art and will not be described in detail herein.

The air inlet 33 is a venturi tube, and one end of the communicating pipe 5 is communicated with the throat of the venturi tube 33. Specifically, the venturi 33 has an hourglass-shaped structure, and has a funnel-shaped inlet 331, an outlet 333, and a venturi throat 332 between the inlet 331 and the outlet 333, wherein the diameter of the venturi throat 332 is smallest, and the diameters of the inlet 331 and the outlet 333 gradually increase outward from the venturi throat 332. The characteristics of the venturi tube 33 are: when the gas flow flows inside the venturi tube 33, the dynamic pressure reaches a maximum value at the narrowest point of the pipe, and the static pressure reaches a minimum value, i.e., a vacuum is formed, so that the external gas is continuously sucked into the venturi tube 33. In this way, the suction force generated in the venturi 33 can suck the particulate matter formed in the electrostatic precipitator 4 into the venturi throat 332 through the communicating pipe 5.
