The dust removal device comprises metal frames, net racks, rolling brushes, a connecting device, fixed devices, a driving shaft, a decelerator, a driving device, fixed pulleys, and driving wheels; balance type metal frame mechanisms in pairs and with the equal weight are used, due to the structure of relative balance, the frame structures can be driven to perform up-down reciprocating motion via minimal power provided by a motor and an acceleration system, the roller brush is made to get rid of dust on the wall of a heat exchanger tube, and heat exchange efficiency of the exhaust-heat boiler is improved.
Description
Technical field:
The utility model discloses a kind of balanced type ash cleaner for exhaust-heating boiler, belong to the technical field that the metallurgy industry fume afterheat utilizes, a kind of deashing device of waste heat boiler for flue heat exchanger.
Background technology:
The used rotary kiln device such as cement industry, metallurgy industry, its kiln tail exhaust gas temperature mostly about 300-750 ℃, contains considerable heat.Rationally effectively recycle this part heat, not only can protection of the environment, can also reduce the production cost of enterprise, reach the purpose of energy-saving and emission-reduction.For utilizing this part heat, at present, mostly at the kiln tail waste heat boiler is set and reclaims this part heat, heat generation saturated vapor or the superheated steam of recovery are used for industrial production and generating needs.Institute joins boiler heating surface and generally adopts the transversal flow convection bank.Owing to containing more, thinner dust in the flue gas, the cleaning that ash handling equipment guarantees heating surface need to be set, to improve its heat absorption capacity, reduce exhaust gas temperature, improve heat recovery rate.But because the characteristic of kiln exit gas dust, the dust stratification of heating surface is more sticking, and dust stratification speed is very fast, needs continuously ash disposal, the normal operation of guarantee boiler.At present, adopt the methods such as steam soot blowing, sonic soot blowing, shock-wave ash blowing, although effect is pretty good, if but long-term continuously operation, then operating cost is higher, so the ash handling equipment of kiln tail waste heat boiler heating surface mostly adopts the rapping-off-ash device at present, it can realize the effect of low-cost continuous dust dislodging.
In industrial production, power industry particularly, sonic sludge removing device for boiler is widely used.But using more is as working media take high pressure air, this ash handling equipment is to drive the diaphragm that rotates with buncher or relay to come sounding, owing to existing the compressed air quantity not sufficient with can not keeping away name, need to build again pumping plant, therefore increased installation cost, simultaneously because compressed-air actuated temperature is room temperature basically, strengthened the air leakage coefficient of boiler, affected the thermal efficiency of boiler, in addition, because the restriction of relay and motor, it is very high that the frequency of the matrix of acoustical generator can not reach, and the frequency-tuning range of sounding is narrower, and how in low frequency operation, all can produce harmful effect to operating personnel and equipment, so the application of this Acoustic Wave Ash Disposal Device is limited to very much.
The reciprocating-grate boiler combustion process has blockiness, during burning, the middle part is different with the air capacity that two ends need, thereby generally all adopt zoned air, it is the independent air compartment that is divided into several mutual isolation under the fire grate, each air compartment can be regulated air quantity on demand, has solved the problem of vertical reasonable wind distribution.But still exist the inhomogeneities of width along fire grate (namely horizontal) air-supply, also can cause on the grate burning inhomogeneous.Particularly during single admission, owing to after the air-flow of the fair speed that enters from a side enters air compartment, causing the fire grate cross air dispatching inhomogeneous because axial flow velocity reduces gradually.Boiler combustion efficiency is had a significant impact.For addressing this problem, the 70-71 page or leaf of " miniature boiler design and repacking " (second edition) book that science tech publishing house (1989) publishes has proposed a solution.Wind scoop formula air compartment is namely arranged below reciprocal grate, and air enters wind scoop formula air compartment through air register, and air register is along the fire grate lateral arrangement, and air can be very even along the horizontal distribution of fire grate like this.The air channel, system storehouse of one " cross section is very large " need to be set below air compartment in this scheme, the volume (particularly height) of boiler is increased.Complicated integral structure makes troubles also for the air compartment ash disposal.
Chinese patent 200920259080.7 discloses a kind of device removing dust of boiler convection tube banks by rapping.Although this device improves prior art, but still adopted every pair of pipe row chain sling and rapping clamping plate to be connected with two tubulation row suspension clamps, only being connected with a tubulation row suspension clamp than original every pair of pipe row chain sling and rapping clamping plate, to take transverse width little, the pipe column pitch is diminished, but volume is still larger.Staggered arrangement is adopted in the tube bank of being heated, and has improved the heat transfer coefficient of the tube bank of being heated, and reduces heat pipe quantity, has saved the tube bank space, and the height of boiler also can correspondingly reduce, and can save a large amount of steel; But can not well eliminate the dust stratification of the tube bank of being heated, serious dust stratification can occur; Can not well save the making apparatus investment, simplify the bend pipe operation.Chinese patent 201120035965.6 also discloses a kind of Novel ash removing device for boiler, changed original boiler and surveyed quick-fried system with the sound that ash handling equipment adopts, and it is quick-fried to adopt pressure to change survey, has strengthened and has surveyed quick-fried accurate reliability; Action postpones for blasting and soot blowing, pulse generation tank mist burns insufficient problem, makes ignition flame stream that fast rotational occur, and intensity increases, and speed is accelerated, and has improved ignition success rate, and reliability strengthens, and makes the mist burning more abundant; Also designed the air curtain blocking device, solved partially mixed gas and entered the problem that burner hearth produces waste and causes potential safety hazard.But this device also can't thoroughly be eliminated the defective of prior art, and cost is high, and maintenance difficulty is large etc.
The utility model device adopts paired equiponderant balanced type metal framework mechanism, metal framework mechanism is made of rack, round brush, heat-transfer pipe, elastic compensating device etc., because the structure of relative equilibrium, provide small power driver framework mechanism to pump by motor, retarder system, the dust that round brush will be adhered on the exchanger tube wall removes, and improves the heat exchange efficiency of waste heat boiler.Round brush adopts metallic fiber or non-metallic fibers material to make, and is linked as the integral net shelf structure by elastic compensating device, is installed on the balanced type metal framework again.This system is provided with various protections and control device.The utility model has the efficient operation of guaranteeing waste heat boiler concurrently, improve the characteristics such as heat exchange efficiency.
