Abstract
The utility model designs a heat pipe type waste heat boiler. The utility model is used for generating superheated vapour, wherein, the gauge pressure of which is 3.82 MPa, the temperature of which is 450 DEG C according to the steam parameter desired by the common waste heat recovery. The utility model comprises a superheater, a steam drum, an evaporator, and coal economizers. The utility model is characterized in that the superheater 2 is divided into two sections, the middle is provided with a desuperheater 3, one end of the superheater 2 is connected with the steam drum 4 by a connecting pipe, a circulation loop is formed between the evaporator 5 and the steam drum 4 by the connecting pipe, one end of a finned tube type coal economizer 6 is connected with a heat pipe coal economizer 7 by the connecting pipe, and the other end is connected with the steam drum 4 by the connecting pipe.
Description
The utility model belongs to a kind of novel waste-heat recovery device, specifically a kind of heat pipe waste heat boiler.
Waste heat boiler is made up of superheater, convection current evaporator section, economizer and four parts of drum usually, and convection current evaporator section wherein and economizer are as follows at the structural shape that more generally uses at present:
1, traditional convection current evaporator section is the structural shape of upper and lower barrel transverse, the steam-generating bank heating surface of arranging between upper and lower drum is often selected the form of light pipe or extended surface tube for use, the exit is that a slice membrane type finned-tube bundle do to cut off usefulness, flue gas at vertical tube bundle outer surface through baffling several times after enter subordinate's heating surface by the passage outside the membrane type finned-tube bundle.Upper drum is a drum.
2, the economizer structural shape of steel pipe type normally adopts snakelike light pipe or the finned tube heating surface as economizer, and it enters drum after with feed-water preheating.
The convection current evaporator section that waste heat boiler is traditional and the structural shape of economizer, the critical problem of some that exist as the deposition of dust in the waste gas and to cold end corrosion of the burn into economizer of heating surface etc., makes that device lifetime is short, maintenance cost is high.
The purpose of this utility model then is the problem that exists at above-mentioned prior art, has designed a kind of heat pipe waste heat boiler, and the steam parameter requirement required according to general waste heat recovery is 450 ℃ superheated steam in order to produce gauge pressure 3.82Mpa, temperature.
The purpose of this utility model can reach by following measure:
A kind of heat pipe waste heat boiler, comprise superheater, drum, evaporimeter, economizer, it is characterized in that superheater 2 is divided into two sections, intermediate arrangement attemperator 3, superheater 2 one ends link to each other with drum 4 by tube connector, form closed circuit by tube connector between evaporimeter 5 and the drum 4, fin tube type economizer 6 one ends link to each other with heat pipe economizer 7 by tube connector, and the other end links to each other with drum 4 by tube connector.
The main heating surface of heat pipe waste heat boiler is made up of superheater, finned-tube bundle formula evaporimeter, fin tube type economizer, heat pipe economizer, and high-temp waste gas is emptying after entering above-mentioned heating surface successively.
The utility model has following advantage compared to existing technology:
Make traditional convection current evaporator section into finned-tube bundle formula evaporimeter, main advantages is: (1) finned tube outer surface can be welded with the ratio-frequency welding fin, with the expansion heat-transfer area; (2) indivedual tube banks damage, and will organize the tedge of restraining and down-comer and seal and get final product stove outside, and afterheat boiler system still can continue production; (3) solder joint on the drum also greatly reduces, and has improved the security of device.
The economizer component is high temperature section and low-temperature zone, and high temperature section adopts the structural shape of fin tube type economizer, and low-temperature zone adopts the structural shape of heat pipe economizer.The advantage of the economizer group of Bu Zhiing like this: (1) high temperature section adopts finned tube as heating surface owing to avoided the dew point corrosion problem, makes equipment volume reduce, compact conformation, and cost reduces; (2) heat pipe economizer of low-temperature zone, its evaporator section also can twine the ratio-frequency welding fin, expands heat-transfer area, can also control the wall temperature of heating surface effectively, avoids the dew point corrosion of waste gas.
Fig. 1 is a structural representation of the present utility model.
Below in conjunction with accompanying drawing the utility model is further described:
The course of work of heat pipe waste heat boiler is as follows: waste gas is by regenerated flue gas import 1 access to plant, and superheater 2 adopts the suspended structure of snakelike light pipe, is divided into two sections, intermediate arrangement attemperator 3.During nominal situation, attemperator 3 cuts out; When the waste gas overtemperature, attemperator 3 work make out the steam of superheater 2 remain on about 450 ℃.Form closed circuit by tube connector between finned-tube bundle formula evaporimeter 5 and the drum 4.The feedwater of drum 4 is supplied with after successively passing through heat pipe economizer 7 and 6 preheatings of fin tube type economizer by cold water.Waste gas goes out heat pipe economizer 7 backs and is discharged by regenerated flue gas outlet 8.
