Double-filter counter-rotating supergravity wet dust collector, including a casing, with an air inlet on the side wall of the casing, a dust removal chamber in the middle of the casing, and an outer ring filter element in the middle of the dust removal chamber. The cross-section of the ring filter element in the horizontal direction is circular, the axis of the outer ring filter element is in the vertical direction, the bottom end of the outer ring filter element is fixed on the turntable, the middle part of the turntable is connected to the top of the vertical shaft, and the vertical shaft extends downward through the Through the bottom plate of the casing, the bottom end of the vertical shaft is coaxially connected with the motor shaft of the motor, the motor is fixed on the bottom plate, the top of the outer ring filter element is fixed with an upper partition one, and the upper end surface of the upper partition one is connected to the lower end of the transmission connection plate The surfaces are attached to each other, and the middle part of the upper end surface of the transmission connection plate is fixedly connected with the bottom end of the hollow transmission sleeve. Its purpose is to provide a dual-filter counter-rotating supergravity wet dust collector with higher dust removal efficiency, more stable dust removal performance, and more thorough removal of various very fine particles.

A composite dust collecting plate for electrostatic dust collection comprises a dust collecting electrode (1) made of conductive materials, and a dust suction layer (2) made of silk-shaped or porous materials is arranged on the surface of the dust collecting electrode (1); and the conductivity of the silk-shaped or porous materials for forming the dust suction layer (2) is 1*10<-8>S / m to 1*10<-5>S / m. According to the composite dust collecting plate for electrostatic dust removal, the dust containing capacity is high, the time period needing by dust cleaning is long, the efficiency of cleaning particles with the equivalent diameter smaller than or equal to 2.5 micrometers is high, and the dust removal performance is very stable.

The invention discloses a clean and environment-friendly dust collector for a grain storage and cleaning center. The clean and environment-friendly dust collector comprises an enclosure, an air suction and dust collection chamber, a dust collecting and filtering chamber, a centrifugal draught fan and a dust collection and treatment system, wherein the dust collection and treatment system comprises a dust collection ash bucket communicated with the dust collecting and filtering chamber, a packing auger conveyor, a driving and speed reducing motor and an air-locked ash outlet. Dust, which is blown by the dust collecting and filtering chamber to fall off, falls into the dust collection ash bucket and the packing auger conveyor is used for conveying dust impurities to the air-locked ash outlet to be intensively collected; a bag pressing plate is used for tightly pressing the edge of a dust collection bag to a side wall of an air-locked ash outlet body; the dust collection bag does not need to be manually held and the dust is convenient to collect so that time and labor are saved; a storage dust-collection air duct is provided with a plurality of independent air chambers for carrying out independent dust collection on materials in material storage channels and the independent air chambers are not influenced with one another; negative-pressure strength is great and uniform and the dust collection effect is good; the dust collection chamber is internally provided with a plurality of multi-air-duct cage frameworks so that the dust-collection and filtering area is large and the dust collection stable effect is good.

The invention relates to the technical field of industrial equipment, in particular to a dust removal device applied to the production of coated sand. Compared with the prior art, the dust removal device for the production of coated sand is provided with a filter screen on the air inlet filter device. The upper and lower ends of the cylindrical cylinder are equipped with nozzles, which spray water and remove dust through convection. At the same time, high-pressure air is passed through the four high-pressure punching holes to make the air in the cylindrical cylinder turbulent, so as to increase air and water. In order to increase the dust removal effect, a water baffle and a wind baffle are installed at the air outlet. On the one hand, it can trap water droplets in the air, and on the other hand, it also solves the problem of direct current wind. Through these layers of filtration, It can completely dissolve the dust in the air into the water. The most important thing is that its structure is simple and the design is reasonable. It is almost impossible to cause clogging, dust removal failure and other failures. It has the advantages of reasonable structure, good use effect, low failure rate and stable dust removal.

The present invention provides a gas cooler capable of being reduced in size, capable of preventing exhaust gas from leaking to the outside, and capable of stably removing dust. The gas cooler (1) of the present invention has: a plurality of cooling pipes (5), which are arranged in the cooling chamber (3); dust removal parts (7), which are slidably arranged on the peripheral surface of the cooling pipes; reciprocating A moving mechanism (9), which makes the dust removal component reciprocate along the axial direction of the cooling pipe. The reciprocating mechanism is provided with: a holding member (17), which holds the dust removal member reciprocally movable and protrudes in a direction intersecting with the axial direction of the cooling pipe; an opening (19), which is provided on the side wall (3a) of the cooling chamber ), which enables the holding member to protrude from the side of the cooling chamber and reciprocates; a sealing mechanism (21), which prevents the gas in the cooling chamber from leaking to the outside; a moving body (22), which supports the holding member protruding from the opening and capable of reciprocating movement; and a drive mechanism (24) that reciprocates the moving body.
