Description
Technical field
The present invention relates to heat-exchange device field, be specially a kind of air preheater with air purge device.
Background technology
To be exactly flue gas in boiler back end ductwork will enter air preheat before the boiler heating surface to uniform temperature by inner fin with air preheater.For improving the heat exchange performance of boiler, low-energy-consumption falls.Generally referred to as air preheater.Be used for coal-fired power station boiler.Can be divided into two kinds of box type, swingings.Wherein, bobbin carriage preheater operation principle is comparatively simple, and flue gas is from bobbin carriage outer flow warp, and air passes through from bobbin carriage inside, by temperature difference different heat transfer, identical with principles such as economizer, superheaters.
On the other hand, by the heat transfer type of air preheater, air preheater can be divided into heat-conducting and the large class of regenerative two.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 has brought difficulty to the layout of back-end surfaces, separately due to 20% left and right of oxygen in air, existence, in other incombustible foreign gases of amount, affects the efficiency of combustion of boiler.
Summary of the invention
The application's object is to provide a kind of air preheater with air purge device, not high to solve the gas oxygen content of heat exchanger preheating, 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 air preheater with air purge 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) Yu Jun air compartment (10) is connected, described equal air compartment (10) is provided with gas absorption section (12).
Further, described top exchanging tube (8) is made by 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.
Further, described hot air outlet (7) is 2:1 with the bore ratio of air intake (6).
Further, described support (1) bottom is provided with base (2), and base (2) is connected with ground by expansion bolt.
Further, the side of described support (1) is provided with panel (11), and the top of described support (1) is provided with top cover (9).
The present invention has the following advantages:
Gas oxygen content accounting after the utility model preheating is high, and the feature that heat-exchange tube conducts heat according to different phase flue gas adopts different materials to make, and has improved wind-heat conductivity, has overcome the problem that heat exchanger back-end surfaces need to expand.

The specific embodiment
As shown in Figure 1, the air preheater with air purge device comprises support (1), 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 the air preheater that support tool has air purification devices, on the top with the air preheater of air purge device, be provided with smoke inlet (4), at its symmetrical opposite side, be provided with exhanst gas outlet (5), because flue gas is by after having the air preheater of air purge device, gas is because temperature declines, 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 of the air preheater with air purge device, air enters into equal air compartment (10) after by air intake (6), flow through bottom exchanging tube (3) to top exchanging tube (8) again, finally by hot air outlet (7), discharge and have outside the air preheater of air purge device, because air temperature after having the air preheater of air purge device rises, volume increases, therefore, it is large that the relative aperture air intake (6) of hot air outlet (7) is wanted, ratio is advisable with 2:1.
For purifying enters the gas in equal air compartment (10), improve the oxygen content of preheating gas, in Jun air compartment (10), be provided with gas absorption section (12), gas absorption section (12) is the ferrum-based catalyst of nitrogen conversion, when gas passes through gas absorption section (12), airborne nitrogen content reduces, and from face, common oxygen accounting is improved.
At the top of support (1), be provided with top cover (9), can be used for the working condition that cleaning and detection have the air preheater of air purge device, on the other hand, owing to thering is the air preheater of air purge device, can produce vibration in the course of the work, in order to reduce vibration equipment, make pipeline connect loosening, therefore, in the bottom of support (1), be provided with base (2), base (2) by the fastening installation of expansion bolt on the ground.
The top exchanging tube (8) that is 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, due to the flue gas top exchanging tube (8) of first flowing through, there is good wearability, flue gas is section high temperature but have compared with severe corrosive just, select stainless steel not easy to wear on the one hand as the heat exchange material of top exchanging tube (8), the first section of flue gas can be passed to air by more heat on the other hand, bottom exchanging tube (3) aluminium alloy is because flue gas needs better to pass material at afterbody, the corrosivity of flue gas declines simultaneously, therefore, do not need to increase tail area and can reach equally good biography effect.
As shown in Figure 2, in the side with the air preheater of air purge device, be provided with panel (11), thereby make to have globality, the better tightness of the air preheater of air purge device.
