Description
Technical field
The utility model relates to a kind of combustion gas and electrical heating dual-purpose vacuum stove, especially utilize the dual-purpose vacuum stove of wind electric & gas, belong to energy heating equipment technical field.
Background technology
At present, traditional vacuum hot water unit is all the heating equipment of the single energy, or fuel oil or combustion gas, or electricity consumption is directly heated; This heating equipment is when running into certain energy starved, and corresponding equipment just cannot use.
Utility model content
The purpose of this utility model is the deficiency overcoming prior art existence, and provide a kind of rational in infrastructure, compact, easy to use and reliable, the area of boiler room can be reduced, reduce equipment cost, reduce cost of use, improve the thermal efficiency of vacuum drying oven and the combustion gas in service life and electrical heating dual-purpose vacuum stove.
The purpose of this utility model has been come by following technical solution, a kind of combustion gas and electrical heating dual-purpose vacuum stove, it comprises one by cylindrical shell, front tube sheet and back tube sheet form, the body of heater of vacuum can be kept, the jackshaft of body of heater is to being provided with gas furnace hearth, the front end of this burner hearth is provided with furnace outlet and the front smoke chamber around furnace outlet, rear end is provided with return combustion chamber and the rear smoke chamber around return combustion chamber, described rear smoke chamber is communicated with vertically arranged chimney, electrothermal tube is furnished with in described body of heater, and described electrothermal tube passes through base fixing seal in body of heater, medium soft water is after treatment poured in described body of heater, described upper of furnace body is provided with heat exchanger.
The utility model is preferably: the shroud outside described front smoke chamber and electric heating base be all weldingly connected with front tube sheet and evagination before body of heater; Be horizontally connected with smoke pipe in the body of heater of described burner hearth periphery, and the two ends of described smoke pipe and electrothermal tube are welded to connect with front tube sheet and back tube sheet respectively.
The utility model is preferably: be provided with wet back splint layer in the outside of return combustion chamber by supporting short circuit; Described burner hearth is single-ended to be welded on front tube sheet, and the cylindrical shell of furnace body outer wall is welded with heat exchanger, and described rear smoke chamber, return combustion chamber are soldered respectively at back tube sheet.
The utility model is the improvement done on the basis of existing vacuum drying oven, and electrothermal tube is arranged in its tube sheet outer ring before and after common vacuum drying oven, and electrothermal tube in body of heater, keeps the vacuum in body of heater by base fixing seal simultaneously.In the process used, preferentially use electric energy, if when electric power is not enough, electrical control can brake switching, use natural gas, burner is started working.WATER AS FLOW MEDIUM due to vacuum drying oven is through the disposable soft water be filled with in stove after process, in use neither increases and does not also reduce, body part non flouling behaviour this, improve electricity, the thermal efficiency of gas dual-purpose vacuum stove and service life.
The utility model has rational in infrastructure, compact, easy to use and reliable, can reduce the area of boiler room, reduces equipment cost, reduces cost of use, the features such as the thermal efficiency of raising vacuum drying oven and service life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail: shown in Fig. 1, a kind of combustion gas described in the utility model and electrical heating dual-purpose vacuum stove, it comprises one by cylindrical shell 1, front tube sheet 3 and back tube sheet 16 form, the body of heater of vacuum can be kept, the jackshaft of body of heater is to being provided with gas furnace hearth 4, the front end of this burner hearth 4 is provided with furnace outlet 5 and the front smoke chamber 2 around furnace outlet, rear end is provided with return combustion chamber 14 and the rear smoke chamber 12 around return combustion chamber, described rear smoke chamber 12 is communicated with vertically arranged chimney 11, electrothermal tube 8 is furnished with in described body of heater, and described electrothermal tube 8 passes through base fixing seal in body of heater, medium soft water 10 is after treatment filled with in described body of heater, described upper of furnace body is provided with heat exchanger 9.
Shown in figure, the utility model preferred embodiment is: the shroud 7 outside described front smoke chamber 2 and electric heating base be all weldingly connected with front tube sheet 3 and evagination before body of heater; Be horizontally connected with smoke pipe 6 in the body of heater of described burner hearth 4 periphery, and the two ends of described smoke pipe 6 and electrothermal tube 8 are welded to connect with front tube sheet 3 and back tube sheet 16 respectively.
The further preferred embodiment of the utility model is: be provided with wet back splint layer 13 in the outside of return combustion chamber 14 by supporting short circuit 15; Described burner hearth 4 is single-ended to be welded on front tube sheet 3, and the cylindrical shell 1 of furnace body outer wall is welded with heat exchanger 9, and described rear smoke chamber 12, return combustion chamber 14 are soldered with back tube sheet 16 respectively.
The fuel that the Northwest's heating boiler generally uses is natural gas and coal, because the pollution of coal is very large, progressively transform now, natural gas is main fuel, a kind of free energy-wind energy is also had in Xinjiang, the wind-powered electricity generation clean environment firendly that wind energy sends, cost are low, but the impact of wind-powered electricity generation climate is larger, electricity is not had without wind, therefore wind-powered electricity generation is difficult to be incorporated to national grid, can only use on the spot, so can adopt electrovacuum boiler in the area of wind-powered electricity generation prosperity, natural gas is auxiliary to be made for overcoming wind-powered electricity generation deficiency.Electricity, gas dual-purpose vacuum stove can reduce the area of boiler room, reduce equipment cost, reduce cost of use.
