Description

The multi-functional cooling tube of low-resistance

Technical field

The utility model relates to flue gas processing device, especially for the multi-functional cooling tube of the low-resistance of flue gas processing.

Background technology

The flue gas of various kilns, electric furnace and boiler needs dedusting, and deduster is efficient high, but resistance loss is too high, also is a very big waste on the energy.Though the dust remover resistance loss that has is low, yet efficiency of dust collection is also very low.At present comparatively advanced deduster has sack cleaner, but because flue-gas temperature is too high, can bring difficulty to the operation of sack cleaner, even cloth bag burnt by high-temperature flue gas, therefore need lower the temperature to flue gas.Traditional flue gas cool-down method has the cold wind of mixing and spray cooling, can cause exhaust gas volumn to increase greatly but mix cold wind separately, and spray cooling can cause the flue gas water content to increase separately, and these all can carry out flue gas ash removal to sack cleaner and bring difficulty.Notification number is that CN2634315Y discloses Chinese patent " combined flue gas cool-down device ", and it is with water injector and mix cooling air unit and organically combine, and keeping flue-gas temperature constant, thereby makes the sack cleaner high-effective dust-removing.It is at first with the working procedure input control device, temperature sensor is constantly passed to control device with data, when flue-gas temperature when constantly rising to the critical point of setting, control device at first starts mixes cooling air unit, open cold-air flap, blower fan is blown a cold wind in exhaust gases passes by cool air hose, flue gas is lowered the temperature, at this moment exhaust gas volumn can constantly increase on the original basis, when exhaust gas volumn increased to the critical point of setting, control device was restarted the spray cooling device, and nozzle is sprayed water in exhaust gases passes, at this moment, these two kinds of heat sinks move simultaneously, and the exhaust gas volumn that makes these two kinds of heat sink operations cause increases and the water content increase is in an Optimal Control value, reaches best of breed, and keep flue-gas temperature constant in certain temperature range, for carrying out flue gas ash removal, sack cleaner creates convenience.After flue-gas temperature was reduced to design temperature, control device quit work two kinds of heat sinks according to predefined program.Though this combined flue gas cool-down device has such-and-such advantage, its exhaust gas volumn of still not avoiding mixing cold wind and spray cooling existence increases and the increase of flue gas water content, and the bag-feeding deduster carries out the shortcoming that flue gas ash removal brings difficulty.

Summary of the invention

Goal of the invention of the present utility model provides a kind of multi-functional cooling tube of low-resistance that need not mix cold wind and spray water flue-gas temperature is reduced, to solve the problems that existing flue gas cool-down equipment and deduster exist.

In order to realize the foregoing invention purpose, the technical scheme that the utility model adopted is: the multi-functional cooling tube of low-resistance, and its feature comprises current divider box, some cyclone separating tubes, some cooling cylinders, some guide vanes, ash-collecting tube, header box, dust collecting box; Have air outlet on the header box, and be installed on the basis by support; Some cyclone separating tubes become vertical state to be supported on the header box with ash-collecting tube, and their bottom is all passed the bottom of header box and is communicated with dust collecting box by ash-collecting pipe; The bottom of each cyclone separating tube be provided with header box in the air outlet of conducting, the top of ash-collecting tube is provided with some adapter tubes that become to be communicated with cyclone separating tube; The bottom support of current divider box is on the top of some cyclone separating tubes, in its case with each cyclone separating tube conducting; On current divider box, be connected with an air intake smoke pipe; Each cooling cylinder becomes vertical state to run through each cyclone separating tube and current divider box respectively; A guide vane that is positioned at each cyclone separating tube top is housed on each cooling cylinder.

The high temperature dust flue gas enters in the current divider box through the air intake smoke pipe, and be evenly distributed in each cyclone separating tube, under the effect of guide vane, the high temperature dust flue gas tangentially enters in the cyclone separating tube and carries out the high speed rotation around cooling cylinder, barrel by cooling cylinder fully with cooling tube in cold air carry out heat exchange, and heated hot-air is by the top discharge of cooling tube.Under the effect of exhausting, cold air constantly automatically enters in the cooling tube from the bottom of cooling tube again, and barrel and high temperature dust flue gas by cooling cylinder carry out heat exchange.High temperature dust flue gas in each cyclone separating tube is by the cold air heat exchange constantly in the cooling cylinder, and temperature imports in the header box after little by little lowering.The ash-laden gas through after the cooling in the header box enters the flue gas mozzle of sack cleaner under the guiding of air-introduced machine, enter the processing of evolving of deduster main body under the guiding of mozzle uniformly; Filter in the dust hopper that the dust that gets off concentrates on deduster regular packed processing through sack cleaner.Cleaned air passes is discharged sky through smoke exhaust pipe from the blast pipe of deduster.In cooling, some particles bigger and redox reaction is taking place and the granule dust that discharges heat of high temperature by eddy flow, collision and interception, a part is separated by adapter tube and is entered in the ash-collecting tube, enter in the dust collecting box again and be collected, another part is separated and concentrates on the bottom of cyclone separating tube, is entered in the dust collecting box by ash-collecting pipe to be collected.

The utility model adopts air force refrigerated separation principle; when reducing the high temperature dust flue-gas temperature rapidly; the granule dust and the bigger particle separation of diameter that will play oxidation reaction effectively and discharge heat of high temperature are come out; thereby protected cloth bag not burnt effectively, improved the operational reliability of deduster by high-temperature flue gas.Because SR reduces, in the power of the supporting air inducing master motor capacitance grade that descended, the operating cost of having saved equipment.
