Description
Technical field
The present invention relates to heat-exchange device field, be specially a kind of with the heat exchanger except dew device.
Background technology
Air preheater is exactly that flue gas in boiler back end ductwork will enter the heating surface of the air preheat before boiler to uniform temperature by inner fin.For improving the heat exchange performance of boiler, reduce energy ezpenditure.General referred to as air preheater.Be used for coal-fired power station boiler.Box type, swinging two kinds can be divided into.Wherein, bobbin carriage preheater operation principle is comparatively simple, and flue gas flows through from bobbin carriage outside, and air passes through from bobbin carriage inside, by temperature difference different heat transfer, identical with the principle such as economizer, superheater.
Air preheater can be divided into heat-conducting and the large class of regenerative two by the heat transfer type of air preheater.The most frequently used in heat-conducting air preheater is tubular air preheater.Along with the raising of boiler parameter and the increase of capacity, the heating surface of tubular air preheater also increases, and this brings difficulty to the layout of back-end surfaces.On the other hand, the low temperature condensation formed at its afterbody metal erosion, can have influence on the bulk life time of air preheater.
Summary of the invention
The object of the application is to provide a kind of with the heat exchanger except dew device, can not except dew to solve heat exchanger afterbody, the problem that wind-heat conductivity reduces.
In order to achieve the above object, the present invention is by the following technical solutions:
A kind of with the heat exchanger except dew device, comprise support (1), bottom exchanging tube (3), top exchanging tube (8), smoke inlet (4), exhanst gas outlet (5), air intake (6) and hot air outlet (7), it is characterized in that: described smoke inlet (4) and hot air outlet (7) are positioned at the homonymy of support (1), described air intake (6) and exhanst gas outlet (5) are positioned at the opposite side of support (1), described top exchanging tube (8) is positioned at the first half of support (1), described bottom exchanging tube (3) is positioned at the latter half of support (1), described air intake (6) is connected with equal air compartment (10), described support (1) top is provided with the conduit (14) stretching out support (1) near exhanst gas outlet (5) place.
Further, described conduit (14) is provided with valve (13), and the end of conduit (14) extend into below the liquid level of liquid-collecting bottle (12).
Further, described top exchanging tube (8) is made up of stainless steel, and described bottom exchanging tube (3) is made by aluminium alloy.
Further, the relative aperture exhanst gas outlet (5) of described smoke inlet (4) is large.
Further, the relative aperture air intake (6) of described hot air outlet (7) is large.

Detailed description of the invention
As shown in Figure 1, support (1) is comprised with the heat exchanger except dew device, base (2), bottom exchanging tube (3), top exchanging tube (8), smoke inlet (4), exhanst gas outlet (5), air intake (6) and hot air outlet (7), its medium-height trestle (1) plays a part to support the heat exchanger with except dew device, smoke inlet (4) is provided with on the top with the heat exchanger except dew device, exhanst gas outlet (5) is provided with at the opposite side of its symmetry, because flue gas passes through with after the heat exchanger except dew device, gas declines due to temperature, volume reduces, therefore, the bore of smoke inlet (4) is greater than the bore of exhanst gas outlet (5), air intake (6) and exhanst gas outlet (5) are in homonymy, be positioned at the latter half with the heat exchanger except dew device, air enters into equal air compartment (10) by after air intake (6), flow through bottom exchanging tube (3) again to top exchanging tube (8), discharge with except the heat exchanger except dew device finally by hot air outlet (7), because air temperature after with the heat exchanger except dew device rises, volume increases, therefore, the relative aperture air intake (6) of hot air outlet (7) wants large, ratio is advisable with 2:1.Be located at the conduit (14) stretching out support (1) near exhanst gas outlet (5) place on the top of support (1), conduit (14) is provided with valve (13), in order to control the discharge of dew, conduit (14) extend in the bottle of liquid-collecting bottle (12), and the opening of conduit (14) is positioned at below the liquid level of liquid-collecting bottle (12).
Top cover (9) is provided with at the top of support (1), can be used for clearing up and detect the working condition with the heat exchanger except dew device, on the other hand, due to can vibration be produced in the course of the work with the heat exchanger except dew device, in order to reduce vibration equipment, pipeline connection is loosened, therefore, be provided with base (2) in the bottom of support (1), base (2) by the fastening installation of expansion bolt on the ground.
The top exchanging tube (8) being positioned at support (1) top adopts stainless steel as heat exchange material, the bottom exchanging tube (3) of its underpart adopts the aluminum alloy materials of high thermal conductivity, because first flue gas flows through top exchanging tube (8), there is good wearability, flue gas just section high temperature but have comparatively severe corrosive, select stainless steel not easy to wear on the one hand as the heat exchange material of top exchanging tube (8), more heat can be passed to air by the first section of flue gas on the other hand, bottom exchanging tube (3) aluminium alloy is then because flue gas needs better to pass material at afterbody, the corrosivity of flue gas declines simultaneously, therefore, do not need increase tail area can reach equally and pass effect preferably.
As shown in Figure 2, be provided with panel (11) in the side with the heat exchanger except dew device, thus make globality, the better tightness with the heat exchanger except dew device.
