Abstract

The utility model discloses a multi-sound wave combined dedusting long bag type deduster, which comprises supports (1), dust hoppers (2), a tank (3), a bag cage (4), a chequered plate (5), an air inlet (7) and an air outlet (8), the tank (3) is fixed on the supports (1), the dust hoppers (2) are fixed on the bottom of the tank (3), the bag cage (4) is arranged in the tank (3), the chequered plate (5) is arranged in the upper part of the tank (3), and the deduster is characterized in that both the dust hoppers (2) and the tank (3) are provided with sound wave dust removers (6). The air consumption of the deduster is little, and the energy consumption for dedusting is reduced; since the sound wave dust removers are arranged in areas where dust cannot be effectively removed, the dedusting radius is enlarged, the phenomena of 'dedusting dead angle' and 'dust hopper bridging' are prevented, the service life of a filter bag is prolonged, the system resistance is reduced, and the dedusting efficiency of the equipment is increased.

Description

The long bag of many sound wave combination ash disposal sack cleaner

Technical field

The utility model relates to a kind of improvement of growing bag sack cleaner, the long bag of specifically a kind of many sound wave combination ash disposal sack cleaner.

Background technology

Long bag sack cleaner great advantage is that efficiency of dust collection height, cost are lower, and be not subjected to the influence of dust than resistance variations, because environmental emission standard is strict day by day, the development space of long bag sack cleaner is increasing, particularly under the unfavorable working conditions such as high temperature, high humidity, high concentration fine dust, hygroscopicity dust, inflammable and explosive dust stronger adaptability being arranged.

The key of long bag sack cleaner is deashing, the quality decision long bag sack cleaner of ash-removal effect and even the success or failure of whole production system.Bad as ash-removal effect, will improve SR, increase the deashing frequency, shorten life-span of the filter bag, traditional pulse backblowing deashing has become a kind of main purge mode of long bag bag-type dusting industry, but in actual applications, because the filter bag long-term work is in hot environment, the electromagnetic impulse valve frequent start-stop, and the defective of Venturi tube self structure or the like reason, be in operation and have following many defectives: 1. the wind-engaging machine negative pressure effect at ordinary times of cloth bag filtrate tightly is adsorbed on the Filter-bag carcass, long-time HTHP makes the easy embrittlement of filtrate quality, during pulse backblowing, moment jetting pressure increase, the rapid dilatancy of filter bag, and directed winding-up makes the filter bag local pressure bigger, causes that filter bag breaks.Break in case indivedual filter bags occur, whole equipment is effluxed exceed standard, if things go on like this, the filter bag spoilage is higher, and the periodic replacement filter bag increases deduster operating cost, and corresponding increase disastershutdown probability; Pulse jet to bleed pressure and air compensation have relatively high expectations, air consumption is big, the frequent unlatching of pulse valve causes rapid wear, service life short (useful life only is 12～24 months), and costing an arm and a leg; 3. the weakness of flush type Venturi tube self structure makes that sack position 200mm～400mm can't deashing, and outlet diameter dwindles simultaneously, and local acceleration the in airflow passes neck place passed card, and the overall system resistance is increased; 4. pulse jet is when magnetic valve is opened, air-flow is through the instantaneous cloth bag that sprays into of Venturi tube guiding, be subjected to the influence of beam wind and back draught simultaneously, the dilatancy of filter bag is difficult to be diffused into the bottom of growing bag and finishes thorough deashing, unavoidably stay the deashing dead angle, the filter bag bottom thoroughly blocks when serious, makes that efficient reduces, system's operation difficulty.

Summary of the invention

The purpose of this utility model is to provide a kind of deficiency that can overcome existing ash-clearing technology, simple in structure, easy to use, deashing thoroughly, the long bag of the many sound waves combination ash disposal sack cleaners that can improve efficiency of dust collection and prolong its service life.

For reaching above purpose, the technical scheme that the utility model adopted is: the long bag of these many sound wave combination ash disposal sack cleaner, comprise that support, ash bucket, casing, bag cage, card, air inlet and air outlet constitute, casing is fixed on the support, ash bucket is fixed on the bottom of casing, is provided with a bag cage in casing, is provided with card on the top of casing, air inlet and air outlet are located at respectively on the right side, left side wall of casing, it is characterized in that: be equipped with sound wave ash cleaner on ash bucket and casing.

The utility model is also implemented by following measure: described sound wave ash cleaner, constitute by oscillator, compressed air hose, magnetic valve and sound wave generator tube, rear end at the sound wave generator tube is provided with oscillator, the rear end of sound wave generator tube is connected with compressed air hose, compressed air hose connects source of the gas, is provided with magnetic valve on compressed air hose.

Described ash bucket is provided with 10 covers, is all fixing sound wave ash cleaner on the sidewall of every cover ash bucket by corresponding fixed mount.

Respectively by the equidistant fixing last 10 cover sound wave ash cleaners of corresponding fixed mount, also equidistantly fixing 10 cover sound wave ash cleaners on the upper wall of casing respectively by corresponding fixed mount on the sidewall of described casing.

The sound wave ashing principle: sound wave ashing is by a kind of gas, sound converting apparatus converts the mechanical energy of air-flow to acoustic energy, be sent to needed deashing space with certain frequency and sound level, because air is a kind of elastic fluid, cause when compression when being subjected to slight vibration, can always not rest on compressive state, and can be re-inflated, disturbance to contiguous air generation " periodically ", " periodically " the vibration that makes the soot particle on filter bag surface also produce, overcome and the filter bag surface between adhesion and be in " suspension " state, under the effect of air-flow or gravity, break away from attachment surface or soot particle group and be pulled away or sink, thereby reach the effect of deashing; In addition, acoustic vibration belongs to dither for filter bag, and it can make dust loosely organized, makes extremely tough dust, the dust that especially contains micro-moisture be difficult for forming the cake piece on the filter bag surface, is easy to come off.The essence of sound wave ashing is " involving ", because sound wave is comprehensive propagation (through, reflection and refraction etc.), thereby the direction of active force has polytropism, and the effect of other purge modes is " unidirectional ", so sound wave ashing can produce good ash-removal effect.

The beneficial effects of the utility model are: compare with traditional long bag sack cleaner, because the generation of sound wave is lower to the requirement of source of the gas, air consumption is less, can reduce the dedusting energy consumption greatly, by sound wave ash cleaner being arranged on the bad zone of deashing, the installation site is more flexible, increased the deashing radiation scope, deashing " dead angle " and ash bucket " bridge formation " phenomenon have been avoided, prolonged the physical life of filter bag, reduce SR, thereby improved the efficiency of dust collection and the life-saving greatly of equipment.
