Description

Novel combustion vapour vacuum hot water boiler

Technical field

The utility model belongs to boiler technology field, especially novel combustion vapour vacuum hot water boiler.

Background technology

At low-temperature water heating heating field, as central air-conditioning heating, bath hot water etc., vacuum hot water boiler is high with the thermal efficiency, the feature of use safety, convenient management receives market and applies widely, vacuum hot water boiler, be exactly the heat of water vapour that WATER AS FLOW MEDIUM produces in the indirect absorption boiler of inside of boiler heat exchange, the WATER AS FLOW MEDIUM in boiler not with outer loop, water level is lower than heat exchanger, produce water vapour after being heated, during operation in shell pressure lower than atmospheric pressure; Because the aqueous medium temperature of this boiler main heating surface contact is higher, heat transfer temperature difference is little, therefore needs larger size and area to reduce exhaust gas temperature.

Utility model content

The utility model object provides novel combustion vapour vacuum hot water boiler to overcome the deficiencies in the prior art, and heating surface connection and reasonable arrangement, structural safety, operating cost are low, maintenance is convenient, efficient power-saving multiple-purpose vacuum hot water boiler.

For achieving the above object, the technical solution adopted in the utility model is: novel combustion vapour vacuum hot water boiler, comprise combustion chamber, reduction vaporization room, heating heat exchanger, supplying hot water heat exchanger and automatic vacuum-pumping apparatus, it is combustion chamber below described boiler, top is reduction vaporization room, described heating heat exchanger, supplying hot water heat exchanger upper-lower position are configured in reduction vaporization room, and the import and export of described heating heat exchanger and supplying hot water heat exchanger are arranged on the side of reduction vaporization room; The upper surface of described reduction vaporization room is provided with automatic vacuum-pumping apparatus; Side, described combustion chamber entrance location is provided with burner, and opposite side connects exhanst gas outlet; The wall of inner container of described combustion chamber is also set up branched heat exchanger tube and is formed heating surface, and described heat exchanger tube is curved water pipe shape; The afterbody of described combustion chamber is laid with the heat exchanger of condensation recovery.

Improve further as the utility model, described reduction vaporization room one inside be respectively equipped with anti-lack of water temperature inductor, overheatedly prevent temperature sensor, control heat medium temperature perceptron.

Improve further as the utility model, the upper surface of described reduction vaporization room is also provided with Pressure gauge.

Due to the utilization of technique scheme, the utility model compared with prior art has following advantages: novel combustion vapour vacuum hot water boiler of the present utility model, and combustion chamber wall of inner container forms the first heating surface, wall of inner container is also set up branched heat exchanger tube and forms heating surface; The afterbody of combustion chamber lays the heat exchanger of condensation recovery; The combustion product gases of combustion chamber through wall of inner container, set up that branched heat exchanger tube forms heating surface, heat exchanger is reclaimed in condensation, then discharge from exhaust pass; Realize repeatedly fully absorbing of combustion product gases, reduce the exhaust gas temperature of boiler; Effectively increase boiler heating surface, substantially increase the thermal efficiency of boiler; Have reasonable in design, handsome in appearance, the thermal efficiency is high, use hygienic and convenient, nonpollution environment, efficient power-saving multiple-purpose beneficial effect.

Accompanying drawing explanation

Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:

Accompanying drawing 1 is the structural representation of novel combustion vapour vacuum hot water boiler of the present utility model.

Detailed description of the invention

Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments; Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.

As shown in Figure 1, novel combustion vapour vacuum hot water boiler, it is combustion chamber 1 below boiler, top is reduction vaporization room 2, heating heat exchanger 3, supplying hot water heat exchanger 4 upper-lower position are configured in 2 li, reduction vaporization room, and the import and export of heating heat exchanger 3 and supplying hot water heat exchanger 4 are arranged on the side of reduction vaporization room 2; The upper surface of reduction vaporization room 2 is provided with automatic vacuum-pumping apparatus 5; Side, combustion chamber 1 entrance location is provided with burner 6, and opposite side connects exhanst gas outlet 7; The wall of inner container 8 of combustion chamber 1 is also set up branched heat exchanger tube 9 and form heating surface 10; The afterbody of combustion chamber lays the heat exchanger 11 of condensation recovery; The combustion product gases of combustion chamber 1 through wall of inner container 8, set up the heat exchanger 11 that branched heat exchanger tube 9 forms heating surface 10, condensation is reclaimed, then discharge from exhanst gas outlet 7; Reduction vaporization room 2 one inside be respectively equipped with anti-lack of water temperature inductor 12, overheatedly prevent temperature sensor 13, control heat medium temperature perceptron 14; The upper surface of reduction vaporization room 2 is also provided with Pressure gauge 15.

The utility model novel combustion vapour vacuum hot water boiler, realizes repeatedly fully absorbing of combustion product gases, reduces the exhaust gas temperature of boiler; Effectively increase boiler heating surface, substantially increase the thermal efficiency of boiler; Have reasonable in design, handsome in appearance, the thermal efficiency is high, use hygienic and convenient, nonpollution environment, efficient power-saving multiple-purpose beneficial effect.

Below be only embody rule example of the present utility model, protection domain of the present utility model is not constituted any limitation; The technical scheme that all employing equivalents or equivalence are replaced and formed, all drops within the utility model rights protection scope.
