Abstract

The utility model discloses a cold condensation type and energy saving heat dispersing device, which comprises a heat exchanging pipe and a rectangular outer cover that can be communicated with a fume gas pipeline. Wherein, the outer cover has a fume gas adjusting and clocking plate nearby the fume gas charging cut; the position close to the other end of the adjusting and blocking plate has a flow guiding plate that is paralleled with the central line of the fume gas charging cut. The lower part of the flow guiding plate also has a support plate with the upper surface paralleled with the flow guiding plate. The one end of the support plate is jointed with the sidewall of the charging cut and the other end is connected with the outer cover basal plate nearby the fume gas discharging cut. The two passages respectively formed between the flow guiding plate and the support plate, between the flow guiding plate and the outer cover wall each has at least one heat exchanging pipe group. The utility model respectively adopts the high efficiency heat exchanging pipe group to absorb the physical sensible heat in the fume gas and adopts the vaporization potential heat of the water vapor to heat the media. In this way, not only the energy is saved, also the temperature of the discharged gas is reduced. The utility model answers for the national policy of energy saving and environmental protection, and also brings the consumers along with the economic and practicable interest.

Description

The energy-conservation heat-exchanger rig of condensing

Technical field:

The utility model relates to heat-exchange device, is the energy-conservation heat-exchanger rig of a kind of condensing that utilizes the waste heat of flue gas to heat to medium on a kind of exhaust pipe that is installed in fuel oil or gas fired-boiler and relevant combustion heating equipment concretely.

Background technology:

Existing fuel oil or gas fired-boiler and relevant combustion heating equipment, contain a large amount of heat energy during its work in the tail gas and do not obtain reasonable use, cause the waste of the energy, though existing heat exchanger tube technology can be given the heating of the medium in the pipeline, is contained in also not finding on the exhaust tail gas in actual applications.

Summary of the invention:

The purpose of this utility model provides a kind of energy-conservation heat-exchanger rig of condensing that can rationally utilize the exhaust tail gas on fuel oil, gas fired-boiler or the miscellaneous equipment to heat for the medium in the heat exchanger tube.

The technical solution of the utility model is finished as follows, the energy-conservation heat-exchanger rig of a kind of condensing of the present utility model, it includes heat exchanger tube, it is characterized in that: also have the rectangle housing that can be connected with flue, in housing, be provided with a rotating gas proportioning damper near the gas approach place, near the controllable register other end one deflector parallel with the gas approach center line arranged, the deflector below also has the gripper shoe that upper surface is in parallel, gripper shoe one end is connected on the wall of inlet side, an other end is connected near on the housing base plate of smoke outlet, the set of heat exchange tubes that many heat exchanger tubes of a usefulness are made is installed between deflector and gripper shoe and in two passages that form between deflector and the housing wall at least, or the housing that communicates of gas flue in be lower than on the position of set of heat exchange tubes and be provided with a condensate spill over pipe that leads to outside the housing.The utility model is given the heating of the medium in the heat exchanger tube by the heat that set of heat exchange tubes efficiently absorbs in the flue gas, waste heat when effectively utilizing fume emission had both been saved the energy, had reduced the temperature of discharging gas again, meet the energy-saving and environmental protection policy of country, it is economical and practical that the user has been obtained.

Description of drawings:

Fig. 1 is a structural representation of the present utility model.Among the figure, 1. gas approach, 2. controllable register, 3. housing, 4. set of heat exchange tubes, 5. flow apron, 6. exhanst gas outlet, 7. gripper shoe, 8. condensate spill over pipe, 9. leg.

The specific embodiment:

Further specify an embodiment of the present utility model in conjunction with above accompanying drawing, the energy-conservation heat-exchanger rig of this condensing, it is that existing efficient heat-exchanging pipe is processed into set of heat exchange tubes 4, a rectangle housing 3 that can be connected with the flue of fuel oil or combustion gas pot is processed in the outside, housing bottom has leg 9, in housing, be provided with a rotating gas proportioning damper 2 near gas approach 1 place, be used for regulating the flue gas ratio of set of heat exchange tubes 4 of flowing through, near the controllable register other end one deflector 5 parallel with gas approach 1 center line arranged, deflector 5 belows also have a corner supports plate 7 that upper surface is in parallel, corner supports plate 7 one ends are connected on the wall of gas approach side, the other end is connected near on the housing base plate of smoke outlet, set of heat exchange tubes 4 is installed in the passage that forms between deflector 5 and the corner supports plate 7, be provided with one and lead to the outer condensate spill over pipe 8 of housing on the housing bottom wall of the riser of corner supports plate 7 and exhanst gas outlet 6 one sides, the condensed water of generation can be discharged thus during the flue gas ventilation.The utility model is given the heating of the medium in the heat exchanger tube by the heat that set of heat exchange tubes efficiently absorbs in the flue gas, as boiler feedwater, domestic water etc., this device not only can absorb the physics sensible heat in the flue gas, and the latent heat of vaporization that can also the absorption portion water vapour, improve the effective rate of utilization of heat energy, saved the energy, reduced the greenhouse effects of atmosphere, meet the energy-saving and environmental protection policy of country, it is economical and practical that the user has been obtained.

Claims

1, the energy-conservation heat-exchanger rig of condensing, it includes heat exchanger tube, it is characterized in that: also have the rectangle housing that can be connected with flue, in housing, be provided with a rotating gas proportioning damper near the gas approach place, near the controllable register other end one deflector parallel with the gas approach center line arranged, the deflector below also has the gripper shoe that upper surface is in parallel, gripper shoe one end is connected on the wall of inlet side, an other end is connected near on the housing base plate of smoke outlet, and the set of heat exchange tubes that many heat exchanger tubes of a usefulness are made is installed between deflector and gripper shoe and in two passages that form between deflector and the housing wall at least.
