Abstract
The utility model discloses a centrifugal rotational flow steam waste heat boiler. The centrifugal rotational flow steam waste heat boiler comprises a high-temperature flue gas inlet pipe, a flue gas centrifugal rotational flow chamber, a steam boiler body, a low-temperature flue gas outlet, a steam generator, a boiler water pre-heater and a soft water inlet pipe. The flue gas centrifugal rotational flow chamber is formed in the upper portion in the steam boiler body, the flue gas centrifugal rotational flow chamber is provided with the high-temperature flue gas inlet pipe, the steam generator is located in the center in the steam boiler body, the low-temperature flue gas outlet is formed in the steam generator, the boiler water pre-heater is arranged on the periphery of the steam generator, and the soft water inlet pipe is arranged at the lower end of the steam boiler body. According to the centrifugal rotational flow steam waste heat boiler, a dust remover and a flue gas waste heat boiler are integrated in the same device, dusty flue gas cannot abrade the boiler and high-temperature flue gas cannot cause damage or dust removing effect reduction to the dust remover.
Description
Technical field
The utility model relates to a kind of boiler, particularly relates to a kind of centrifugal rotational flow boiler using steam residual-heat.
Background technology
The industrial flue gas that often has 1000 degree left and right, dustiness is higher, no matter with any deduster, all fails, and for dedusting, after flue gas is lowered the temperature by cooling column, drops to below 200 degree, is entering deduster.This method is used in steel-making enterprise and chemical enterprise in a large number.A kind of existing method is by first not dedusting of flue gas, directly sends waste heat boiler to and carries out energy-conservation recovery, and flue gas cool-down, creates normal dedusting condition., the heating surface of waste heat boiler under the impact of many dirt and wearing and tearing, damages very fast, blowing out overhaul in new boiler some months, replacing boiler tube, cost is high like this.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of centrifugal rotational flow boiler using steam residual-heat, it is made in same device by deduster with smoke and waste steam boiler, many cloud of dust gas does not does not wear and tear to boiler, and high-temperature flue gas deduster is not formed to infringement or effect falls in dedusting, reduces costs.
The utility model solves above-mentioned technical problem by following technical proposals: a kind of centrifugal rotational flow boiler using steam residual-heat, it is characterized in that, it comprises high-temperature flue gas inlet tube, flue gas centrifugal cyclone chamber, steam boiler, low-temperature flue gas outlet, steam generator, pot water preheater, soft water inlet tube, steam boiler inner and upper is provided with flue gas centrifugal cyclone chamber, flue gas centrifugal cyclone chamber is provided with high-temperature flue gas inlet tube, steam generator is positioned at steam boiler central interior, steam generator inside is provided with low-temperature flue gas outlet, pot water preheater is located at steam generator periphery, soft water inlet tube is located at steam boiler lower end.
Preferably, described steam boiler top is also provided with steam outlet pipe.
Preferably, described steam boiler below is provided with cigarette ash discharge pipe.
Preferably, described pot water preheater outer wall is provided with ash fall wall.
Preferably, the width of described ash fall wall reduces successively from top to bottom successively.
Positive progressive effect of the present utility model is: the utility model deduster is made in same device with smoke and waste steam boiler, and many cloud of dust gas does not does not wear and tear to boiler, and high-temperature flue gas deduster is not formed to infringement or effect falls in dedusting.High-temperature flue gas access to plant just obtains dedusting and cooling, and during the outlet of flow of flue gas auto levelizer, flue gas is just cooled to design low-temperature values.The operating wall temperature of device is in a safe condition all the time.The heat energy that the temperature difference of smoke entrance is paid is absolutely changed into available energy by working medium absorption in boiler.Boiler plate, with grit contact, is not eliminated to ash dropping hopper, has protected the safety of boiler and has improved service life, reduces costs.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model centrifugal rotational flow boiler using steam residual-heat.
Fig. 2 is the structural representation of the utility model centrifugal rotational flow boiler using steam residual-heat partial component.
The specific embodiment
Below in conjunction with accompanying drawing, provide the utility model preferred embodiment, to describe the technical solution of the utility model in detail.
As depicted in figs. 1 and 2, the utility model centrifugal rotational flow boiler using steam residual-heat comprises high-temperature flue gas inlet tube 1, flue gas centrifugal cyclone chamber 2, steam boiler 4, low-temperature flue gas outlet 5, steam generator 6, pot water preheater 7, soft water inlet tube 8, steam boiler 4 inner and upper are provided with flue gas centrifugal cyclone chamber 2, flue gas centrifugal cyclone chamber 2 is provided with high-temperature flue gas inlet tube 1, steam generator 6 is positioned at steam boiler 4 central interior, steam generator 6 inside are provided with low-temperature flue gas outlet 5, pot water preheater 7 is located at steam generator 6 peripheries, soft water inlet tube 8 is located at steam boiler 4 lower ends.
Steam boiler 4 tops are also provided with steam outlet pipe 3, facilitate like this exhaust steam.Steam boiler 4 belows are provided with cigarette ash discharge pipe 9, convenient like this by cigarette ash discharge, prevent dust stratification.Pot water preheater 7 outer walls are provided with ash fall wall 10, like this can sedimentation dust.The width of ash fall wall 10 reduces successively from top to bottom successively, so convenient concentrating and sedimentation dust.
During work, many cloud of dust of high temperature gas, from high-temperature flue gas inlet tube 1 access steam boiler 4, flows within flue gas centrifugal cyclone chamber 2, and by dust separation, to ash fall wall 10, concentrated dust enters cigarette ash discharge pipe 9 and discharges; Clean flue gas enters low-temperature flue gas outlet 5 and discharges.Aspect boiler, the required demineralized water of boiler enters pot water preheater 7 from soft water inlet tube 8, before the water that reaches capacity, enters steam generator 6, collects in steam generator top from steam outlet pipe 3 outputs.
The rotation of flue gas access to plant in hypervelocity, dustiness particle is subject to great centrifugal action and is thrown to ash fall wall, the centrifugal force of rotation particle is directly proportional with rotary speed square, with radius of turn, be inversely proportional to, this device dwindles radius of turn greatly in design size and configuration aspects, strengthens flow velocity.Dust contained flue gas particle is all thrown to wall in an instant and sedimentation is pooled to ash dropping hopper.Cleaning flue gases carries out heat exchange on ash fall wall, and device becomes smoke and waste steam boiler, carries out heat exchange, and at heat exchanging process, the design of this device becomes heat transfer temperature difference maximum, and flue gas flow resistance is minimum, has used countercurrent heat-transfer principle.
Above-described specific embodiment; the technical problem of solution of the present utility model, technical scheme and beneficial effect are further described; institute is understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
