Description
[technical field]
The utility model is about a kind of cleaner, is meant a kind of heavy streaming filter cartridge dust remover especially.
[background technology]
Heavy streaming filter cartridge dust remover is to be widely used for a kind of equipment of effectively purifying as dust on the industry, and this product utilization gravity and descending air-flow by the ultra micro filter cylinder, reach more than 99% the filterability of submicron particle.
The structure of existing heavy streaming filter cartridge dust remover is made up of dirt pocket 1, filter cylinder 2, gas storage bag 3, winding-up pipe 4, electromagnetic impulse valve 5, pulse control instrument (figure does not show), air-purifying chamber 6, flue-dust retainer 7, housing 8 etc. as shown in Figure 1.Housing 8 inside are divided into dirt pocket 1 and air-purifying chamber 6 by a dividing plate 12.The top of dirt pocket 1 is provided with air inlet 14, and the bottom of air-purifying chamber 6 is provided with air outlet 62.Filter cylinder 2 laterally is set on the support (figure does not show) that supports filter cylinder 2 in the dirt pocket 1, the one end sealing of filter cylinder 2, an end open wide, an end that opens wide is inclined upwardly frame on dividing plate 12, the opening of corresponding filter cylinder 2 is offered one hole on the dividing plate 12, the end that filter cylinder 2 opens wide compresses by sealing ring and dividing plate 12, corresponding to filter cylinder 2 positions Venturi tube 22 corresponding to filter cylinder 2 quantity is installed on the dividing plate 12, an end opening of Venturi tube 22 is aimed at the opening of filter cylinder 2 just, and other end opening stretches into air-purifying chamber 6.Venturi tube 22 normally is welded on the dividing plate 12.Gas storage bag 3 is arranged on the outside of air-purifying chamber 6, winding-up pipe 4 corresponding to Venturi tube 22 quantity is installed on it, adorn the electromagnetic impulse valve 5 of a control winding-up pipe 4 foldings on each winding-up pipe 4, each winding-up pipe 4 outer wall that pass air-purifying chamber 6 stretches into air-purifying chamber 6, and the opening of each winding-up pipe 4 faces the opening of corresponding Venturi tube 22.
Dusty gas is under the effect of negative-pressure air-flow, enter dirt pocket 1 from the air inlet 14 of deduster, by the filtration of filter cylinder 2, dust is separated from air-flow, the clean gas that has been cleaned enters air-purifying chamber 6 from filter cylinder 2 is inner through Venturi tubes 22, is discharged by air outlet 62 then.
When dust filters through filter cylinder 2, the outer surface that dust is stayed filter cylinder 2 forms the ash cake layer, when the filtration dust reaches certain thickness or certain hour, the deduster running resistance strengthens, for being controlled in the restricted portion, resistance (is generally 120～150mmH2O), deduster is provided with the differential pressure transmitter (or pressure controller table) or the time relay, online detection dirt pocket 1 and air-purifying chamber 6 pressure reduction, when pressure reduction reaches setting value, send signal to pulse control instrument, send instruction by pulse control instrument and trigger each electromagnetic impulse valve 5 of unlatching in order, make the compressed air in the gas storage bag 3 be ejected into each corresponding Venturi tube 22 (claiming a time wind) by winding-up pipe 4 each eyelet that are fixed on the gas storage bag 3.Induce during by Venturi tube 22 surrounding air (claiming secondary wind) that is several times as much as a wind to enter filter cylinder 2 at high velocity air, cause 2 moments of filter cylinder sharply to expand.Because the acting in opposition of air-flow, make the long-pending dust releasing that is attached on the filter cylinder 2, after electromagnetic impulse valve 5 is closed, produce back draught once more, filter cylinder 2 is bounced back rapidly, form one bloated one and contract, form the shake of filter cylinder 2 harmomegathus, the long-pending muffin that is attached to filter cylinder 2 outsides comes off because of effect of inertia, makes filter cylinder 2 obtain upgrading, and the dust that is fallen clearly falls into the flue-dust retainer 7 of dirt pocket 1 bottom.
No. the 99208655.8th, Chinese patent, name are called heavy streaming pleated filter cartridge deduster and also disclose a kind of deduster that is similar to said structure.
Existing worry tube deduster uses injecting pulse air flow mostly, sends instruction by pulse control instrument and triggers each pulse valve of unlatching in order, makes the compressed air in the gas bag be ejected into each corresponding Venturi tube by each eyelet of winding-up pipe.Induce the surrounding air that is several times as much as a wind to enter filter cylinder at high velocity air during by Venturi tube, cause filter cylinder moment sharply to expand, make the long-pending dust releasing that is attached on the filter cylinder.After pulse valve cuts out, produce back draught once more, filter cylinder is bounced back rapidly, form one bloated one and contract, form the shake of filter cylinder harmomegathus, the long-pending muffin that is attached to the filter cylinder outside comes off because of effect of inertia, make filter cylinder obtain upgrading, the dust that is fallen clearly falls into the ash bucket of deduster bottom.Actual motion finds that the effect of reverse gas cleaning is not very desirable.In addition, the wind speed at equipment air inlet place is higher, thereby causes first row's filter cylinder serious wear at air inlet place, and the life-span is short, treatment effect is low.
