Detailed Description
A dust removing device comprises a support 1, a dust removing box 2 with upper and lower ends both open is arranged on the upper portion of the support 1, an annular fixing plate 3 is arranged on the upper portion of the dust removing box 2, a motor 4 is arranged on the fixing plate 3, a gear 5 is arranged on an output shaft of the motor 4, a fluted disc 6 is rotatably arranged on the upper portion of the fixing plate 3 and meshed with the gear 5, a plurality of venturi tubes 7 are embedded in the fluted disc 6, the lower portion of each venturi tube 7 is provided with and communicated with a vertical dust removing filter bag 8, the lower portion of the dust removing box body 2 is provided with and communicated with an ash bucket 9, a horizontal air inlet 10 is arranged on the side wall of the ash bucket 9, a dust collecting box 11 is arranged on the lower portion of the ash bucket 9, an air bag 12 and a clean air box 13 are respectively arranged on the fluted disc 6, an injection tube 14 is communicated with the air bag 12, the injection tube 14 is arranged in the clean air box 13. The fluted disc 6 is a disc with teeth on the periphery. During dust removal, dust-containing gas enters the dust removal box 2 from the gas inlet 10, clean gas penetrates through the dust removal filter bag 8 and is discharged from the venturi tube 7 and the gas outlet 15, dust is attached to the outer surface of the dust removal filter bag 8 and is continuously increased, so that the resistance of the dust removal filter bag 8 is continuously increased, and in order that the resistance of the dust removal filter bag 8 does not exceed 1200Pa, the dust removal filter bag 8 can continuously work, and dust on the dust removal filter bag 8 needs to be periodically removed. During dust removal, compressed air in the air bag is blown into the dust removal filter bag 8 through the venturi tube 7 by a nozzle of the blowing tube 14, so that the dust removal filter bag 8 is rapidly expanded in a short time, dust is shaken off along with the reverse action of air flow, and falls into the dust collection box 11, and the purpose of dust removal is achieved. The control motor 4 can drive the fluted disc 6 to rotate through the gear 5, so that the dust removal filter bags 8, the injection tube 14 and the gas purification box 13 rotate, dust-containing gas impacts the rotating dust removal filter bags 8, and the dust removal filter bags 8 uniformly bear the impulsive force of the gas, so that the service lives of the dust removal filter bags 8 are prolonged, the damage time of the dust removal filter bags is consistent, the times of shutdown and replacement are reduced, and the dust removal efficiency is improved. This structure enables the air bag 12 and the blowing tube 14 to rotate together with the venturi 7, and prevents the blowing tube 14 from failing to correspond to the venturi 7 when they rotate independently. The structure also has the advantages of simple structure, convenient maintenance and low cost.
An observation window 16 is arranged on the dust removal box 2. The structure is convenient for people to observe the conditions of all parts in the dust removal box 2.
The dust-removing filter bag 8 is made of polyester needle felt. Because the production material of environmental protection brick has the multiple, the dust material in the workshop also is different. Therefore, the material of the dust filter bag 8 should be considered according to the temperature, moisture content, acid-base property, dust viscosity, dust concentration, and the like of the dust-containing gas. The water content of the dust-containing gas is smaller, when the dust-containing gas is not acidic, the temperature is normal temperature or less than 130 ℃, the dust-removing filter bag 8 is 500-550g/m2The polyester needle felt. When the temperature is less than 250 ℃, aramid Nomex needled felt or 800g/m2Glass fiber needled felt or 800g/m2Weft double glass fiber fabric or fluorine Meisi high temperature filter material (fluorine-containing gas can not be glass fiber material). When the water content is high and the dust concentration is high, a waterproof and oil-proof filter material (or called an anti-condensation filter material) or a membrane filter material (a base fabric is a needle felt subjected to waterproof treatment) is preferably selected. When the dust-containing gas contains acid and alkali and the gas temperature is less than or equal to 190 ℃, Leiton (Ryton polyphenylene sulfide) needled felt is usually selected. The gas temperature is less than or equal to 240 ℃, and when the acid and alkali resistance requirement is not too high, P84 (polyimide) needled felt is selected. When the dusty gas is inflammable and explosive gas, the antistatic terylene needled felt is selected, and when the dusty gas has certain moisture and is inflammable and explosive gas, the waterproof, oilproof and antistatic terylene needled felt is selected.
And a control instrument is arranged on the fixed plate 3 or the clean air box 13, an electromagnetic pulse valve is arranged on the blowing pipe 14, and the control instrument is connected with the electromagnetic pulse valve. The controller and the solenoid pulse valve are not shown in the figure. The controller and the electromagnetic pulse valve are of the existing structure. The controller can control the opening and closing of the electromagnetic pulse valve, so that ash removal is facilitated.
Technical scheme of the utility model not be restricted to the utility model the within range of embodiment. The technical contents not described in detail in the present invention are all known techniques.
