Description
Technical field:
The utility model belongs to energy-saving field, relates 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, consumption steel material is few, cost is low, safe and convenient to use, its production in recent years and use scale development extremely rapid, has been 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, ubiquity fuel consumption is large, high fume temperature, the problem that operating thermal efficiency is low.
Utility model content:
The purpose of this utility model 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, has improved the boiler operatiopn thermal efficiency.
The purpose of this utility model solves by the following technical programs:
A kind of heat pipe flue gas waste heat recovery apparatus, comprise the water jacket cylindrical shell being 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 exhanst gas outlet flange is connected with 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 boiler blow-down water mouth.
Described heat pipe and the welding of water jacket cylinder inboard wall around even interlaced arrangement, heat pipe axial space inclined position is placed.
Described heat pipe is 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 boiler chimney sectional area.
Described ferrous materials is mild steel.
The beneficial effects of the utility model are: reduced normal-pressure boiler fuel consumption, reduced exhaust gas temperature, improved the boiler operatiopn thermal efficiency.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model;
Wherein: 1 is gas approach flange; 2 is 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 utility model is described in further detail:
Referring to Fig. 1, by steel inner casing, become jacket structure for water cylindrical shell with 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, to be serially connected in boiler and chimney root connects exhaust gases passes.Water jacket cylindrical shell be welded up and down outlet pipe and water inlet pipe, to be serially connected on heating system water return pipeline.When hot smoke gas flow is in the middle of water jacket, after reducing flue-gas temperature, heat pipe heat absorption discharges.After heat pipe heat absorption, reach water jacket 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 in heating system and outlet pipe.Thereby reduction fuel consumption, improves boiler thermal output.
Described gas approach flange is connected with boiler flue gas outlet, and exhanst gas outlet flange is connected with 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 boiler blow-down water mouth.
Described heat pipe and the welding of water jacket inwall around even interlaced arrangement.Heat pipe axial space inclined position is placed.
In 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 gas approach flange is connected with boiler flue gas outlet flange, and exhanst gas outlet flange is connected with flue gas flange at bottom.Water inlet pipe and outlet pipe are serially connected in heating system loop, and water inlet pipe is connected with heating system return pipe, and outlet pipe is connected with boiler blow-down water mouth.Heat pipe and the welding of water jacket inner casing around even interlaced arrangement.The hot smoke gas flow of boiler emission is absorbed heat by heat pipe when retracting device, 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 1, thereby improves boiler thermal output.
Heat pipe is gravity type super heat-conductive pipe, and slant setting is answered, α ≯ 65 ° 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 boiler chimney sectional area.
It is all mild steel that 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, do not departing within the scope of technical solution of the present invention, when can utilizing the method for above-mentioned announcement and technology contents to make a little change or being modified to the equivalent embodiment of equivalent variations, in every case be the content that does not depart 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.
