Description
Technical field
The utility model relates to a kind of bag dust collector injection system cooling device, mainly for the treatment of Wind Volume high-temperature dust-containing flue gas sack cleaner, belongs to the environmental protection equipment technical field.
Background technology
In recent years, the high-temperature dust-containing flue gas that the industries such as cement, iron and steel, chemical industry, metallurgy produce all generally adopts large-scale hag filter to carry out purified treatment.The jetting deashing system that is made of parts such as pulse valve, gas bag, bag chamber injection tube, lift valves is one of core technology of such deduster.The design of existing injection system is: by each bag chamber, a gas bag and a lift valve are installed respectively along the center line both sides of bag dust collector air inlet and air outlet direction, some bag chamber injection tubes are installed on each gas bag, every bag chamber injection tube is passed gas bag inside and is connected with the pulse valve that install at the gas bag top, flue gas after purification is by the sack upper space, by the effect of lift valve, enter the air-out flue by bag chamber air outlet.
In conventional design, each gas bag is fixed on the bag dust collector top by some injection tubes of stretching out the bag dust collector top, and gas bag and top cover distance are very near, and the cylinder of lift valve is directly installed on the bag dust collector top cover.Each parts move under long-time hot environment, understand the aging of acceleration pulse valve film, lift valve pneumatic element and sealing ring and electromagnetic valve coil, high temperature has also caused distortion, the weld seam of the parts such as gas bag and bag chamber injection tube to burst simultaneously, thereby both affected the safe and stable operation of whole system, increased again operating cost.Existing design relies on natural air cooling for high-temperature flue gas fully, and cooling-down effect is extremely limited.
The utility model content
The purpose of this utility model is the deficiency for prior art, " cement kiln dust and nitrogen oxide reduce discharging critical material and application technology exploitation " project (bullets: 2011BAE29B00) requirement according to " 12 " national science and technology supporting plan, provide a kind of rational in infrastructure, operation feasible, can obviously reduce each parts environment temperature of injection system, reduce bag dust collector operating cost, improve the bag dust collector injection system cooling device of operation stability, security.
Its technical scheme is: a kind of bag dust collector injection system cooling device, comprise the jetting deashing system that is consisted of by pulse valve, gas bag, injection tube and lift valve, it is characterized in that: be arranged on the bag dust collector top along between gas bag and lift valve and bag dust collector top cover in each bag chamber on air inlet and air outlet direction center line both sides, correspondence is serially connected with gas bag and converges bellows and lift valve and converge bellows respectively, and gas bag converges between bellows and lift valve remittance bellows respectively by the first pipeline UNICOM; Gas bag in each bag of UNICOM chamber, bag dust collector both sides converges bellows and lift valve and converges between the first pipeline of bellows, by the second U-shaped pipeline UNICOM; With on the first pipeline of the second U-shaped pipeline UNICOM, flap valve is housed all; Between the second U-shaped pipeline and cooling blower by pneumatic stopping valve UNICOM.
its technique effect is: compare with conventional design, the utility model is by arranging gas bag remittance bellows and lift valve remittance bellows, with gas bag and lift valve and the isolation of bag dust collector top cover, strengthen and the top board distance, simultaneously the gas bag in each bag chamber is converged bellows and lift valve and converge bellows, by the first and second U-shaped pipelines and cooling blower UNICOM, pressure is carried out wind cooling temperature lowering to injection tube and lift valve, thereby make the diaphragm of pulse valve, the pneumatic element of lift valve and sealing ring and electromagnetic valve coil etc. are under suitable temperature conditions works, delay its ageing process, extend its service life, can prevent also simultaneously that distortion, the weld seams of welding assembly under the condition of high temperature such as gas bag and bag chamber injection tube from bursting, and to guarantee the whole system safe and stable operation, saves operating cost.In addition, by the synergy of cooling blower stop valve and flap valve, can carry out the air quantity adjusting and switch any gas bag remittance bellows and lift valve remittance bellows.Be specially adapted to process the sack cleaner of Wind Volume, high-temperature dust-containing flue gas.

The specific embodiment
As shown in Figure 1, 2, a kind of high temperature bag dust collector pulse jet system thermal compensation device comprises the jetting deashing system that is made of pulse valve, gas bag, injection tube and lift valve.Be arranged on the bag dust collector top along between gas bag and lift valve and bag dust collector top cover 3 in each bag chamber on air inlet and air outlet direction center line both sides, correspondence is serially connected with gas bag and converges bellows 1 and lift valve and converge bellows 2 respectively, and gas bag converges between bellows and lift valve remittance bellows respectively by the first pipeline 4 UNICOMs; Gas bag in each bag of UNICOM chamber, bag dust collector both sides converges bellows and lift valve and converges between the first pipeline of bellows, by the second U-shaped pipeline 5 UNICOMs; With on the first pipeline of the second U-shaped pipeline UNICOM, flap valve 9 is housed all; Between the second U-shaped pipeline and cooling blower 6 by pneumatic stopping valve 8 UNICOMs.
Be equipped with temperature indicating device 7 on above-mentioned gas bag remittance bellows 1.
Its course of work is: cooling blower 6 and bag dust collector run-in synchronism, according to the temperature that is arranged on temperature indicating device 7 demonstrations on bag chamber gas bag remittance bellows 1, by the synergy of pneumatic stopping valve 8 with flap valve 9, control the cold wind air quantity of cooling blower, enter respectively in each bag chamber gas bag remittance bellows 1 and lift valve remittance bellows 2 by the second U-shaped pipeline 5 and the first pipeline 4, thereby realize cooling to each bag chamber injection tube and lift valve cylinder, and then reach the purpose in the pneumatic element of the diaphragm that extends pulse valve, lift valve and sealing ring and electromagnetic valve coil service life; Can prevent also simultaneously that welding assembly distortion, the weld seams such as bag chamber gas bag and bag chamber injection tube from bursting, and to guarantee the whole system safe and stable operation, saves operating cost.
