Abstract
The utility model discloses a surplus heat reusing device for a coal and fuel oil steam boiler, which is characterized in that a fume outlet, a dust remover, a secondary heat exchanger and a primary heat exchanger of the coal and fuel oil steam boiler are orderly communicated by a discharge flue; a draught fan is arranged at the fume outlet of the primary heat exchanger; a water replenishing pipe is introduced into the primary heat exchanger from the bottom, is led out from the top, and is communicated with the bottom of the secondary heat exchanger; a water inlet pipe of a water pump is let out from the front side of the upper part of the secondary heat exchanger, and is connected with the left side of the water pump; and a water supply pipe is let out from the right side of the water pump, and is connected with the boiler. The utility model solves the problem that the existing coal and fuel oil steam boiler can not fully use the high-temperature flue gas produced during working. The utility model is suitable for the reusing of surplus heat in the discharge flue of the coal and fuel oil steam boiler.
Description
Technical field
The utility model relates to the steam boiler application, a kind of specifically isolated plant that waste heat coal-fired, the oil-fired steam boiler smokejack carries out recycling that is used for.
Background technology
At present, the fire coal that uses is gone up by society at present, the high-temperature flue gas that oil-fired steam boiler is produced when work directly is discharged in the air, does not make full use of the heat in the flue gas, causes the waste to resource.
Summary of the invention
The utility model is the problem that high-temperature flue gas that solution fire coal, oil-fired steam boiler are produced can not be to work the time makes full use of, and designs a kind of isolated plant that the recycling parts are housed.
The technical solution of the utility model is, a kind of coal and oil steam boiler waste heat re-use device, comprise deduster, feed pump, filling pipe, smokejack, its special character is: smokejack is successively with fire coal, the exhaust opening of oil-fired steam boiler, deduster, secondary heat exchanger, a heat exchanger UNICOM, air-introduced machine is installed in the smoke outlet of a heat exchanger, filling pipe enters from the bottom of a heat exchanger, the top is drawn with the secondary heat exchanger bottom and is communicated, pump water inlet is drawn from front side, secondary heat exchanger top with the water pump left side and is connect, and boiler feed pipe is drawn with boiler from the water pump right side and connect.The filling pipe left end is provided with magnetic valve, and ball float, microswitch, overflow pipe are installed in the secondary heat exchanger top, and the dedusting funnel is installed in heat exchanger, deduster bottom, and the boiler feed pipe right-hand member is installed check-valves.
During work, connect the water source, press battery main switch, this moment, ball float was in the lower position, and microswitch loses the thrust of ball float and closure, magnetic valve are opened, moisturizing enters heat exchanger No. one time, enter secondary heat exchanger again after water is full, when water level rose to desired location, the ball float action promoted microswitch by pull bar and disconnects, closed electromagnetic valve, moisturizing is finished.Open air-introduced machine, high-temperature flue gas in the smokejack is by heat exchanger and secondary heat exchanger, rise to the top behind the water expanded by heating in heat exchanger heat pipe, enter secondary heat exchanger then, the water in the secondary heat exchanger continues to absorb heat, expanding to rise is stored in the top.For the security of operation of heat exchanger, the restriction of the pressure that produces when not being subjected to water level up and down, the top is provided with the decompression overflow pipe.When boiler need feed water, the water pump action, the water supply that the secondary heat exchanger top has higher temperature enters boiler.Boiler feedwater finishes, and water level descends in the secondary heat exchanger, and ball float descends thereupon, and microswitch closure, magnetic valve are opened, and repeat said process after the moisturizing once more.
Technique effect of the present utility model is, adopts above-mentioned technical scheme, can realize the device that a kind of high-temperature flue gas that coal-fired, oil-fired steam boiler is produced when the work carries out recycling.
Description of drawings
Fig. 1 is a structural front view of the present utility model, and the accompanying drawing that makes an abstract.
Fig. 2 is the cut-away view of heat exchanger of the utility model or secondary heat exchanger.
Fig. 3 is the longitudinal sectional view of heat exchanger of the utility model or secondary heat exchanger.
In the drawings, 1 filling pipe, 2 magnetic valves, No. 3 heat exchangers, 4 smokejacks, 5 secondary heat exchangers, 6 ball floats, 7 microswitches, 8 overflow pipes, 9 dedusters, 10 boilers, 11 check-valves, 12 boiler feed pipes, 13 dedusting funnels, 14 water pumps, 15 pump water inlets, 16 air-introduced machines.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further specified.
As shown in the figure, smokejack 4 is successively with the exhaust opening of coal-fired, oil-fired steam boiler 10, deduster 9, secondary heat exchanger 5, heat exchanger 3 UNICOMs, air-introduced machine 16 is installed in the smoke outlet of a heat exchanger 3, filling pipe 1 enters from the bottom of a heat exchanger 3, draw at the top communicates with secondary heat exchanger 5 bottoms, pump water inlet 15 is drawn from front side, secondary heat exchanger 5 top with water pump 14 left sides and is connect, and boiler feed pipe 12 is drawn from water pump 14 right sides with boiler 10 and connect.Filling pipe 1 left end is provided with magnetic valve 2, and ball float 6, microswitch 7, overflow pipe 8 are installed in secondary heat exchanger 5 tops, and dedusting funnel 13 is installed in heat exchanger, deduster 9 bottoms, and boiler feed pipe 12 right-hand members are installed check-valves 11.
During work, connect the water source, press battery main switch, this moment, ball float 6 was in the lower position, and microswitch 7 loses the thrust of ball float and closure, magnetic valve 2 are opened, moisturizing enters heat exchanger 3 No. one time, enter secondary heat exchanger 5 again after water is full, when water level rose to desired location, ball float 6 actions promoted microswitch 7 by pull bar and disconnect, magnetic valve 2 cuts out, and moisturizing is finished.Open air-introduced machine 16, high-temperature flue gas in the smokejack 4 is by heat exchanger 3 and secondary heat exchanger 5, rise to the top behind the water expanded by heating in heat exchanger 3 heat pipe, then enter secondary heat exchanger 5, the water in the secondary heat exchanger 5 continues to absorb heat, expanding to rise is stored in the top.For the security of operation of heat exchanger, the restriction of the pressure that produces when not being subjected to water level up and down, the top is provided with the overflow pipe 8 that reduces pressure.When boiler 10 needs feedwater, water pump 14 actions, the water supply that secondary heat exchanger 5 tops have higher temperature enters boiler 10.Boiler 10 feedwater finish, and water level descends in the secondary heat exchanger 5, and ball float 6 descends thereupon, and microswitch 7 closures, magnetic valve 2 are opened, and repeat said process after the moisturizing once more.
