Abstract
The utility model relates to an air deflector device which is installed in a heat exchanger and is capable of changing the flow direction and the speed of a part of the heated air. The heat exchanger existing in the prior art is a new flue gas waste heat recovering device with high efficiency. Because the wind channels in the heat exchanger are distributed unreasonably, the quantity and the speed of the input air of each heat exchange tube are different, a plurality of rows of heat exchange tubes near the end of the heat source are easy to burn out and deform, and the equipment is damaged. The utility model changes the distribution of the flow direction of the input air of the existing heat exchanger, improves the reasonable flow of the air and the cooling condition of the heat exchange tubes of the heat exchanger, prevents the superheating phenomenon of the heat exchange tubes of the air at the hot end, avoids the damage of a part of the heat exchange tubes and extends the service life of the heat exchanger.
Description
The utility model relates to a kind of air guide device that can make the part heated air change flow direction and speed of installing in heat exchanger.
Present existing heat exchanger is a kind of new and effective flue gas waste heat recovery apparatus.It is mainly by an inlet suction port, air inlet air compartment, hundreds of heat exchange steel pipes, bellows, give vent to anger air compartment and an air outlet adapter are formed down.Its purposes is mounted in air blast on the inlet suction port and cold air is become high-temperature gas after by the fume afterheat heating through the pipeline of heat exchanger sends into and carry out air blast in the burner hearth, can improve the thermal efficiency of fuel like this, and energy-saving effect is remarkable.But, cause number row heat exchanger tube easy burn-out distortion, and equipment is damaged near heat source side because the air channel irrational distribution of this heat exchanger inside causes each heat exchanger tube intake different with intake velocity.
The purpose of this utility model is that the flow direction that changes wind pushing air in the existing heat exchanger distributes, improve the state of cooling of the heat exchanger tube of the Rational flow of air and heat exchanger, prevent the superheating phenomenon of hot junction air heat exchanger tube, avoid the damage of part heat exchanger tube, prolong the service life of heat exchanger.
The utility model has designed a kind of a kind of air conducting part flow arrangement that is installed in the heat exchanger at the problems referred to above, solves the problem of above existence effectively.
Below in conjunction with Figure of description the utility model is elaborated.
As shown in the figure, the structure of heat exchanger mainly is made up of air outlet [1], flow distribution plate [2], air inlet [3], air inlet air compartment [4], low-temperature zone heat exchanger tube [5], air channel [6], following bellows [7], high temperature section heat exchanger tube [8], the air compartment of giving vent to anger [9].Wherein flow distribution plate [2], air channel [5] are designed for the utility model.
The utility model operation principle is as follows:
The heat exchanger left end is a thermal source, and promptly near smoke outlet, its variations in temperature is to reduce gradually from left to right.Existing heat exchanger is that flow distribution plate [2] and air channel [5] are not installed; Cold air enters in the low-temperature zone heat exchanger tube [8] after air blast is sent into inlet air plenum [4], absorb a part of heat and pass through following bellows and mix, again by the high temperature section heat exchanger tube, another absorbs a large amount of heats, form high-temperature gas through heated cold air at last and enter out air compartment [9], air outlet [1], send into then and carry out air blast in the combustion chamber.Owing to be subjected to the restriction of this structure, the high order end of heat exchanger be temperature the gas in the heat exchanger tube of high part had certain temperature, so the cooling of left end heat exchanger tube is abundant inadequately, is in hot environment for a long time, is easy to left end number row heat exchanger tube is burnt out.The method that the utility model is taked is with the lower air of temperature in the low-temperature zone heat exchanger tube, preferentially sends in the highest number row heat exchanger tube of high temperature section left end heating temperature, and its cooling effect is greatly improved.In order to illustrate in greater detail its principle, see also accompanying drawing.The flow direction of all air is all represented with arrow among the figure.After air enters inlet plenum [4] by air inlet [3], owing to be subjected to the effect of flow distribution plate [2], most of cold air enters in the low-temperature heat exchange pipe on the right, this moment is low because of the temperature on the right, the air of lower temperature enters down bellows the right, because of the buffer action of air channel [9], most of air can only be sent in the heat exchanger tube of high temperature section along the lower end of following bellows, thereby reaches our predetermined purpose.All the other air through the low-temperature zone heat exchanger tube enter in the other heat exchanger tube of high temperature section by air channel [6], following bellows upper end and other little air port.By the effect of the utility model structure in the heat exchanger, make the air flow that enters in the heat exchanger be subjected to certain control and produce rational distribution, and then the district's left end heat exchanger tube that reaches a high temperature is difficult for the purpose that quilt is burnt out.
Air guide device, flow distribution plate [2], air channel [6] that the utility model is designed, simple in structure, fabrication and installation are convenient, are suitable for the transformation of the way of present various tubular type heat exchangers.
Claims (2)
1, a kind of tubular type heat exchanger guiding device is characterized by the steel deflector [2] that has with vertical axis inclination certain angle in heat exchanger inlet plenum [4] left side.
2, install according to claim 1, it is characterized by and in the bellows [7] a steel air channel [6] is being installed down.
