Description

Long bag low pressure sack cleaner
Technical field
The utility model relates to a kind of environmental protection cleaner, is mainly used in to handle the long bag low pressure sack cleaner that a large amount of dust-contained airflows carries out dust catching.
Background technology
China is manufacture of cement and consumption big country, and cement output accounts for the over half of the world, along with the progressively adjustment of China's cement industry, upward changes constantly implementing of little policy greatly, and the process equipment of large quantities of backwardnesss is progressively eliminated, and maximizes, and intensification becomes developing direction.The dust emission of cement industry is a major reason that causes atmosphere pollution.Though, at the kiln hood of cement industry, dust emission points such as kiln tail adopt the glass sack cleaner to handle the dust catching of big air quantity usually at present, but because glass sack cleaner filtration velocity is lower, be generally 0.4~0.5m/s, cause that whole deduster volume is big, floor space is big, investment is high, add that it adopts the blowback bag deashing that contracts, bring extra duty for deduster itself, also influence life of bag filter, limited the development of himself.On the other hand, if adopt the high-voltage pulse bag dust collector, though good effect is arranged, because of its kinetic energy that needs is big, energy consumption is higher, is unfavorable for the energy-saving and cost-reducing of enterprise.Therefore, a kind of sack cleaner of action of low-voltage pulse deashing, long bag constructions that adopts of research is very necessary.
The utility model content
It is a kind of on the basis of pulse jet (Jet Puise) dedusting technology that technical problem to be solved in the utility model is to provide, for satisfying the long bag low pressure sack cleaner of big air quantity flue gas needs.
The utility model for the technical scheme that the technical solution problem adopts is,
A kind of long bag low pressure sack cleaner, it is characterized in that: the casing of described deduster comprises upper box body, middle part casing and ash bucket, ash bucket is arranged on the bottom of middle part casing, in the cabinet space of upper box body and middle part casing formation, a plurality of bags of chambers are set, the indoor placement filter bag of bag, the top has sack, junction at described middle part casing and ash bucket is shaped on fresh air inlet, the top of described upper box body sets out air port and steam vent, described steam vent, the sack of bag chamber links to each other with air-introduced machine with air outlet, to purify back gas and enter atmosphere, travel fatigue is delayed at the filter bag outside.
Also comprise the deashing device, ash-discharging device and the control system that are arranged in the deduster casing, the opening and closing of control system control deashing device and ash-discharging device, described deashing device and ash-discharging device are made of lift valve, electromagnetic impulse valve and winding-up pipe, be electrically connected respectively and between the control system, also be electrically connected between described electromagnetic impulse valve and the winding-up pipe.
Described lift valve is arranged on the top of each bag chamber, and is connected into mutually together with sack, is used to close sack, cuts off the filtered airflow in the bag chamber, electromagnetic impulse valve at compressed air after spray to filter bag by the winding-up mouth on the winding-up pipe.
Described winding-up pipe is made by seamless steel pipe.
Described control system is the deashing controller.
Operation principle of the present utility model is that ash-laden gas enters ash bucket by air inlet through the bottom of middle part casing, the grit that part is bigger is because effects such as inertial collision, natural subsidence directly fall into ash bucket, other grits rise with gas and enter each bag chamber, after filter bag filters, purified gas enters atmosphere through sack, steam vent, air outlet by air-introduced machine from filter bag is inner, and travel fatigue is delayed at the filter bag outside.Along with constantly carrying out of filtering, the appended long-pending dust in filter bag outside constantly increases, thereby cause the resistance of deduster itself also progressively to raise, when resistance reaches certain value, the deashing controller sends signal, at first make the lift valve of one bag of chamber close to cut off the filtered airflow of this chamber, open electromagnetic impulse valve then, compressed air is through gas bag, pulse valve, winding-up mouth on the winding-up pipe sprayed in filter bag with the utmost point short time (0.2-0.3 second), compressed air expands at a high speed in filter bag, make filter bag produce the dither distortion, add the effect of contrary air-flow, the appended dirt cake distortion in the filter bag outside is come off.After the sedimentation time that has taken into full account dust (guaranteeing that the dust that is come off can effectively fall into ash bucket), this bag chamber poppet is opened, this bag chamber returns to the filtration state, and next bag chamber then enters the deashing state, and to the last a bag chamber deashing finishes and so forth.
The beneficial effect that the utlity model has is that deduster adopts off-line or online by bag jetting deashing mode, ash-removal effect is good, efficiency of dust collection is high, at the bottom of the concentration of emission, also have advantages such as the air quantity of processing is big, reliable, easy to maintenance, rational in infrastructure, running resistance is low, floor space is little simultaneously, can be widely used in the big air quantity gas cleaning of industries such as metallurgy, iron and steel, electric power, chemical industry, machinery, building materials.
