Abstract
The utility model relates to a large chambered blowback cloth-bag dust remover, which is composed of a chambered box body, a filter bag device, a dust deposition bucket, a three-way change valve, a dust unloading mechanism, an air inlet pipe, an air accumulating duct, etc. Dusty gas can be purified via alternating filtration and blowback. The utility model overcomes the disadvantages of existing dust removers via adopting the pneumatic sealed three-way change valve, an open-close type pneumatic discharger and the improvement of structural form, the filter bag device and a control system. The utility model has the advantages of high dust removing efficiency, large filtered air flow, simple and reasonable structure, little maintenance, etc. The large chambered blowback cloth-bag dust remover can be used for large systems for environmental protection, dust removal and purification in the fields of metallurgy, building material, mine, etc.
Description
The utility model relates to a kind of large compartment blowback sack cleaner, particularly desirable dusty gas cleaning equipment.
Present employed deduster unreasonable structure, each chamber intake inequality, cause each chamber work unbalanced, there is major defect in employed three-way switch valve, if adopt the electric pushrod driving type, uncontrollable because of torque limit and stroke, fault is frequent, can not satisfy the demand, the scope of activities of cylinder drive piston and cylinder is bigger, the heat insulation work amount is big, needs often maintenance, and their type of belt drive all adopt the turnover plate type structure, in handoff procedure, be in the threeway short-circuit condition, air leak rate of air curtain height, reverse gas cleaning weak effect.Used in addition electronic star cylinder ash valve adopts tooth difference reductor to drive the star wheel rotation and finishes discharging work, often because of reductor spider snap ring, disconnected and the dust of impeller pin card enters increases friction and damage equipment or burn out motor and can't keep and normally unload ash in bearing and the reductor, influence deduster work, present its control system of employed deduster is unreasonable, and do not match with deduster, can not realize automatic control.
The purpose of this utility model is exactly the shortcoming that overcomes above-mentioned prior art, and a kind of efficiency of dust collection height is provided, and it is big, rational in infrastructure to handle air quantity, reliable operation, large compartment's blowback sack cleaner simple to operate.
The purpose of this utility model realizes by following structure, large compartment described in the utility model blowback sack cleaner is mainly by the locellus casing, gas distributing chamber, mozzle, the filter bag device, ash bucket, three-way switch valve, the dust unloadnig apparatus structure, parts such as blast pipe and remittance air channel are formed, wherein three-way switch valve has an air-vent, a back blow port, and normal opening, the normal opening of three-way switch valve is connected with the remittance air channel, described remittance air channel is communicated in the casing internal diameter, several filter bags are arranged in casing, one end of each filter bag connects a mozzle, its other end is connected to an ash bucket through connector, each mozzle of described filter bag all is communicated with gas distributing chamber, and gas distributing chamber is communicated in blast pipe, and above-mentioned ash bucket bottom connects a dust unloadnig apparatus structure.The work of deduster is made up of filtration and the clear two parts of blowback, during filtration, the air-vent of three-way switch valve is opened, back blow port is closed, and the valve of dust unloadnig apparatus structure is also closed, when dusty gas enters the shunting of partition chamber after the water conservancy diversion of each bar filter bag enters each bar filter bag by blast pipe, the gas permeation bag purifies the back and enter the remittance air channel in case, and through converging the air channel by the discharge of the air-vent in the three-way switch valve, at this moment, on the inwall of dust attached to filter bag.When the needs reverse gas cleaning, back blow port in the three-way switch valve is opened, air-vent is closed, clean gas is entered in the casing through the remittance air channel by the back blow port of three-way switch valve, blows filter bag, forms the phase counterblast, filter bag distortion under the effect of air-flow, make the dust releasing that is deposited on the filter bag inwall in ash bucket, pass through the dust unloadnig apparatus structure again, and, dust is got rid of after the unloading valve unlatching.Rationally control each chamber friendship by control system and filter, reverse gas cleaning, thus guarantee the deduster operate as normal.
The closed type Pneumatic three-way transfer valve that the utility model has adopted triple valve to be made up of air-vent, back blow port, normal opening and swing type pneumatic means, realize filtering by the alternation switch of air-vent and back blow port, the work of reverse gas cleaning, overcome in the handoff procedure that existing transfer valve exists and be in the threeway short-circuit condition, the air leak rate of air curtain height, deadly defects such as reverse gas cleaning efficient difference, and also it is flexible to have a switch, advantages such as shell does not produce relative displacement, and power consumption is few.Described shedding mechanism adopts open and close type pneumatic discharge device, it is made up of device for discharging and pneumatic means, drive main shaft by pneumatic means and do 90 ° of reciprocating motions and realize the work of opening and closing, it has solved existing discharger rotor blade and bearing easily blocks, the problem of motor easy burn-out.The utility model has been done optimal design to the structure of its deduster, it is even that each chamber inlet adds Hand-operated butterfly valve control intake, electric-control system adopts SECO, and pressure reduction control and sequential control pressure reduction are followed the tracks of whole work automatically that three kinds of control modes guarantee to realize deduster.Described SECO is meant controls in chronological order that regularly filter each chamber, reverse gas cleaning; The control of described pressure reduction be meant by the size order control of each chamber inlet outlet pressure differential numerical value filter, reverse gas cleaning; Described sequential pressure reduction tracking is meant just often to control in chronological order monitors each chamber inlet outlet pressure differential numerical value simultaneously, reaches certain value as certain constant pressure difference difference and just preferentially begins to carry out reverse gas cleaning.The utlity model has the efficiency of dust collection height, advantage such as it is big, rational in infrastructure to handle air quantity, and reliable operation is simple to operate, and the repair and maintenance amount is little is widely used in the large-scale environmental protection dust separation system of industries such as metallurgy, building materials, mine, is new generation product.
Further describe structure of the present utility model below in conjunction with accompanying drawing, wherein
Accompanying drawing 1 is the structure diagram of the utility model deduster.
As shown in the figure, when filtering, air-vent in the three-way switch valve (5) is opened, back blow port (6) is closed, dusty gas enters gas distributing chamber (2) shunting after the mozzle (3) of each bar filter bag (4) enters each bar filter bag (4) by blast pipe (1), the gas permeation filter bag purify the back in casing through converging air channel (7), discharge by the air-vent (5) in the three-way switch valve again, in this process on the inwall of dust attached to filter bag (4), when dust deposit is a certain amount of when needing deashing, back blow port in the three-way switch valve (6) is opened, air-vent (5) is closed, enter in the casing through converging air channel (7) by the back blow port (6) of three-way switch valve from the clean gas of clean gas source (not shown), blow filter bag (4), form the phase counterblast, filter bag distortion under the effect of air-flow, make the dust releasing that is deposited on the filter bag inwall in ash bucket (8), after opening through dust unloadnig apparatus structure (9) and unloading valve dust is got rid of again, described ash bucket (8) can be made by gas impermeable material.
