Abstract
The utility model discloses a device for recovering afterheat of waste gas in a boiler, which has good heat recovery effect and long service life. The device comprises a shell. A heat exchanger is arranged in the shell; a clapboard is arranged in the middle of the shell, and divides the shell into two parts, namely an upper part and a lower part; the upper part of the shell is provided with a water box, and two sides of the water box are provided with a water inlet pipe and a water outlet pipe respectively; the lower part of the shell is a heat exchange area, and two sides of the heat exchange area are provided with a smoke inlet and a smoke outlet; and a dust discharge port is reserved below the shell. The device is suitable for recovering the afterheat of the waster gas in the boiler and the like.
Description
Technical field
The utility model relates to a kind of retracting device, relates in particular to a kind of device of recyclable waste gas residual heat.
Background technology
The flue gas of boiler emission, the temperature of smoke evacuation is generally about 200 degrees centigrade, if directly be discharged in the environment, not only causes the waste of the energy, and the environment temperature around the influence, thereby rationally utilizes fume afterheat to seem very necessary.And the common heat exchangers of using in retracting device exists the thermal efficiency low, and heat-exchange tube corrosion easily causes deficiencies such as weak point in service life, thereby influences the waste gas residual heat recovering effect.
The utility model content
The technical problems to be solved in the utility model provides that a kind of recuperation of heat is effective, the boiler waste gas waste-heat recovery device of long service life.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises housing, be provided with heat exchanger in the described housing, be provided with dividing plate in the middle of the described housing, described dividing plate is divided into two parts up and down with housing, housing top is divided into water tank, and its both sides are respectively equipped with water inlet pipe and outlet pipe, and lower housing portion is divided into heat exchange zone, both sides are respectively equipped with into mouth and outlet flue, and described housing below is provided with dust-exhausting port.
As preferably, described heat exchanger is made up of some heat-exchange tubes, and heat-exchange tube is up and down to be arranged.
As preferably, described heat-exchange tube periphery is provided with fin.
As preferably, described heat-exchange tube is a copper tube.
The utility model compared with prior art has following obvious advantage and good effect:
1, recuperation of heat is effective.Because the heat exchange pipe periphery in the utility model is provided with fin, can increase substantially the surface area of heat-exchange tube, improves heat exchanger effectiveness, thereby improve the recuperation of heat effect.
2, long service life.Because the heat-exchange tube in the utility model is a copper tube, and is not perishable, thereby can improve service life.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the cross section enlarged drawing of heat-exchange tube among Fig. 1.
The specific embodiment
Below in conjunction with the drawings and the specific embodiments the utility model is described in further detail:
As 1 figure, shown in Figure 2, the utility model comprises housing 1, is provided with heat exchanger 2 in the housing, and heat exchanger 2 is up and down the heat-exchange tube of arranging 3 by many and forms, and heat-exchange tube 3 is made by copper tube, and its periphery is provided with fin 4; Be provided with dividing plate 5 in the middle of the housing 1, dividing plate 5 is divided into two parts up and down with housing 1, and housing 1 top is divided into water tank 6, its both sides are respectively equipped with water inlet pipe 7 and outlet pipe 8, housing 1 bottom is divided into heat exchange zone 9, and both sides are respectively equipped with into mouth 10 and outlet flue 11, and housing 1 below is provided with dust-exhausting port 12.
