The set of heat pipes are welded on the inner wall of the water sleeve body, a flue gas inlet flange and a flue gas outlet flange are welded at the upper end and the lower end of the water sleeve body respectively, a water outgoing pipe is welded at the top of the water sleeve body, and a water ingoing pipe is welded at the bottom of the water sleeve body. The flue gas inlet flange is connected with a boiler flue gas outlet, and the flue gas outlet flange is connected with the root of a chimney. The water ingoing pipe and the water outgoing pipe are in series connection in a heating system water return pipe, and the water outgoing pipe is connected with a boiler water return port. The flue gas waste heat recovery device for heat pipes has the advantages of reducing fuel consumption of an atmospheric pressure boiler, reducing exhaust gas temperature, and improving operation heat efficiency of the boiler.
Description
Technical field:
The invention belongs to energy-saving field, relate to a kind of small atmospheric boiler flue gas waste heat recovery technology, especially a kind of heat pipe flue gas waste heat recovery apparatus.
Background technology:
Miniature boiler particularly normal-pressure boiler because manufacturing process is simple, the consumption steel material is few, cost is low, safe and convenient to use, its production in recent years and use scale development extremely rapid, be widely used in the every field such as heating, bathing, drinking-water, chemical industry of each enterprises and institutions of China town and country, group, hotel, restaurant, city dweller community.But its technical development is slow, designs, manufacture, install and use in reduced levels, the ubiquity fuel consumption is large, high fume temperature, the problem that operating thermal efficiency is low.
Summary of the invention:
The object of the invention is to overcome the shortcoming of above-mentioned prior art, a kind of heat pipe flue gas waste heat recovery apparatus is provided, thereby has reduced exhaust gas temperature, improved the boiler operatiopn thermal efficiency.
The objective of the invention is to solve by the following technical programs:
A kind of heat pipe flue gas waste heat recovery apparatus, comprise the water jacket cylindrical shell formed by inner casing and shell, the water jacket cylinder inboard wall one group of heat pipe that is welded, the upper and lower two ends of water jacket cylindrical shell be welded respectively gas approach flange and exhanst gas outlet flange, the top of the water jacket cylindrical shell outlet pipe that is welded, the bottom of the water jacket cylindrical shell water inlet pipe that is welded.
Described gas approach flange is connected with boiler flue gas outlet, and the exhanst gas outlet flange is connected with the chimney root.
Described water inlet pipe and outlet pipe are serially connected in to be adopted in dim system return pipe, and outlet pipe is connected with the boiler blow-down water mouth.
Described heat pipe and water jacket cylinder inboard wall weld also even interlaced arrangement around, and heat pipe axial space inclined position is placed.
Described heat pipe is the gravity type super heat-conductive pipe, and its axial space inclined position is placed.
Described inner casing, shell, heat pipe, gas approach flange, exhanst gas outlet flange, water inlet pipe and outlet pipe all consist of ferrous materials, and inner casing transverse cutting area is greater than the boiler chimney sectional area.
Described ferrous materials is mild steel.
Beneficial effect of the present invention is: reduced the normal-pressure boiler fuel consumption, reduced exhaust gas temperature, improved the boiler operatiopn thermal efficiency.
The accompanying drawing explanation:
Fig. 1 is structural representation of the present invention;
Wherein: 1 is the gas approach flange; 2 is the exhanst gas outlet flange; 3 is shell; 4 is inner casing; 5 is heat pipe; 6 is water inlet pipe; 7 is outlet pipe.
The specific embodiment:
Below in conjunction with accompanying drawing, the present invention is described in further detail:
Referring to Fig. 1, become the jacket structure for water cylindrical shell by the steel inner casing with the shell assembly welding, the water jacket body inwall one group of heat pipe that is welded.Cylindrical shell two ends be welded gas approach flange and exhanst gas outlet flange, in order to be serially connected in boiler and the chimney root connects exhaust gases passes.Water jacket cylindrical shell be welded up and down outlet pipe and water inlet pipe, in order to be serially connected on the heating system water return pipeline.When hot smoke gas flow is in the middle of water jacket, after reducing flue-gas temperature, the heat pipe heat absorption discharges.Reach water jacket after heat pipe heat absorption water temperature is raise, the water after temperature raises is back to boiler return water temperature is improved by being serially connected in water inlet pipe on heating system and outlet pipe.Thereby the reduction fuel consumption, improve boiler thermal output.
Described gas approach flange is connected with boiler flue gas outlet, and the exhanst gas outlet flange is connected with the chimney root.
Described water inlet pipe and outlet pipe are serially connected in to be adopted in dim system return pipe, and outlet pipe is connected with the boiler blow-down water mouth.
Described heat pipe and water jacket inwall weld also even interlaced arrangement around.Heat pipe axial space inclined position is placed.
In the heat pipe flue gas waste heat recovery apparatus, gas approach flange and exhanst gas outlet flange are serially connected between boiler flue gas outlet and chimney, and the gas approach flange is connected with the boiler flue gas outlet flange, and the exhanst gas outlet flange is connected with the flue gas flange at bottom.Water inlet pipe and outlet pipe are serially connected in the heating system loop, and water inlet pipe is connected with the heating system return pipe, and outlet pipe is connected with the boiler blow-down water mouth.Heat pipe and water jacket inner casing weld also even interlaced arrangement around.The hot smoke gas flow of boiler emission is absorbed heat by heat pipe when retracting device, the inside heat pipe medium undergoes phase transition heat conduction and reaches in water jacket by water and absorb and make flue gas cool-down, in water jacket, water temperature raises and is back to boiler to improve boiler feed temperature by outlet pipe 7, thereby improves boiler thermal output.
Heat pipe is the gravity type super heat-conductive pipe, and slant setting is answered in its axial space position,
.
That shell and inner casing can be made into is round, square or other geometry, and wherein inner casing transverse cutting area should be greater than the boiler chimney sectional area.
It is all mild steel that the heat pipe flue gas waste heat recovery apparatus is manufactured material.
The above, it is only preferred embodiment of the present invention, not the present invention is done to any pro forma restriction, although the present invention discloses as above with preferred embodiment, yet not in order to limit the present invention, any those skilled in the art, within not breaking away from the technical solution of the present invention scope, when the method that can utilize above-mentioned announcement and technology contents are made a little change or be modified to the equivalent embodiment of equivalent variations, in every case be the content that does not break away from technical solution of the present invention, any simple modification of above embodiment being done according to technical spirit of the present invention, equivalent variations and modification, still belong in the scope of technical solution of the present invention.
