Abstract
The utility model belongs to a hot water heating apparatus in a heating and heat supply system, which comprises a sealing type casing 1, wherein, a fluid medium filling valve 3 and an air suction pipe 8 are fixedly arranged on the casing; the lower part in the casing is fixedly provided with a combustion chamber 2; the outer opening point of the combustion chamber is fixedly provided with a combustion engine 4; an inner end of the combustion engine 4 is fixedly connected with a smoke box 6; an outer end of the smoke box 6 is fixedly provided with a smoke gas outlet 5; the upper part in the casing is fixedly provided with a heat exchange pipe 7; the both ends of the heat exchange pipe 7 are respectively high temperature water outlet 9 and a lower temperature water inlet 10. The machine set of the utility model has the advantages of high heat exchange efficiency, reasonable structure and stable performance. The utility model is an ideal hot water heating device.
Description
The utility model belongs to the hot water firing equipment in the heating system, and specifically heating boiler is a kind of.
The hot water firing equipment that is adopted in the heating system mostly is steam boiler at present, because this steam boiler all is a high-pressure bottle.For high-pressure bottle, not only desired material is better, and manufacture process requirement is also than higher, so its manufacturing cost is than higher.Secondly steam boiler is wanted to work under the environment of high temperature, high pressure for a long time, exists many hidden danger inevitably, even can bring threat to the people's lives and property.Therefore many heating systems change steam boiler into hot-water boiler, this hot-water boiler is wanted directly the water in the heating system to be heated, in to the heating of the water in the system, boiler body also will bear the pressure from heating system, and in fact this hot-water boiler is high-pressure bottle equally.Because the water softening in the system is bad, fouling easily along with constantly thickening of incrustation scale, also can influence the heat exchange of boiler, thereby can reduce the utilization rate of heat energy on the inwall of boiler.
The purpose of this utility model is to provide that a kind of heat exchange efficiency height, volume are little, rational in infrastructure, the heating equipment of stable work in work.
The purpose of this utility model is to realize like this.This hot water unit utilizes that water boiling point under negative pressure state is low, evaporation is fast, meets the characteristics of cold easy condensation, carries out the exchange of heat energy, to reach the rapid heating of the medium in exchange heat pipe and the heat exchanger tube.The housing of this hot water unit is made sealed container, on this housing, be installed with fluid media (medium) injection valve and exhaust tube,, and will be pumped into negative pressure or vacuum state in the housing so that inject heat exchange medium such as water.Bottom in housing is installed with a combustion chamber, and at combustor of the collar extension place of combustion chamber fixed installation, so that flame is burnt in the combustion chamber, the heat energy that is produced heats the fluid media (medium) in the housing, makes it vaporization.Fixedly connected with smoke box in the rear end of combustion chamber, outlet flue of rear end fixed installation of smoke box is so that the flue gas that fuel is produced after combustion chambers burn is by smoke box, outlet flue row mouthful flue.Top in housing is installed with heat exchanger tube, the two ends of heat exchanger tube are respectively high-temperature water outlet and water at low temperature import, so that heating system is connected, water at low temperature is introduced from the water at low temperature import, after the process heat exchanger tube heats water, through the high-temperature water outlet high-temperature water is drawn again, supply with the hot water user and use.
Because the said hot water unit of the utility model is to be pumped into negative pressure or vacuum in the housing, make that the oxygen content in the housing reduces, just avoided the corrosion of gas effectively to casing inner wall.Owing to be pumped into negative pressure or vacuum in the housing, quicken the evaporation rate of heated medium, thereby quickened the rate of heat exchange of heat exchanger tube, improved the utilization rate of heat energy effectively.Because the quantity of housing inner fluid medium is fewer, can fluid medium soften and handle or other modes are handled, prevent the inner walls fouling, pass through the heat transmission of furnace wall to guarantee heat, also help effective utilization of heat energy.Because the housing of this hot water unit does not directly enter employed fluid in the heating system, the body of housing need not bear the pressure of autothermal operation system.In addition, according to different purposes, many group heat exchanger tubes can be installed, in the housing so that the hot water of different purposes to be provided.
Fig. 1 is a structure principle chart of the present utility model;
Fig. 2 is the schematic diagram of the heating system of this hot water unit.
Below in conjunction with accompanying drawing the utility model is described in detail.
The housing 1 usefulness steel plate of this hot water unit is welded into a sealed container, can make the version of horizontal boiler, also can make the version of vertical boiler.Bottom in housing 1 is installed with a combustion chamber 2, so that burn in combustion chamber 2 for fuel or flame, 2 collar extension place is installed with a combustor 4 in the combustion chamber, provides fuel or jet flames in the combustion chamber so that give in the combustion chamber 2.The fuel that its combustor provided can be liquid fuel, also can be gaseous fuel or solid fuel.2 rear end is installed with a smoke box 6 in the combustion chamber, and the outer end of smoke box 6 is installed with an exhanst gas outlet 5, so that the flue gas that fuel combustion produced in the combustion chamber 2 is entered in the chimney.Top in housing 1 is installed with heat exchanger tube 7, and the two ends of heat exchanger tube 7 are respectively high-temperature water water outlet 9 and water at low temperature water inlet import 10, so as with heating system in feed pipe be connected with return pipe.In order in housing 1, to inject heat exchange medium, on housing 1, be installed with a fluid media (medium) injection valve, for the air in the housing 1 being extracted out, make to form negative pressure or vacuum in the housing 1, on housing 1, be installed with an exhaust tube 8.The heat supply principle of this hot water unit is: by the water after heat exchanger tube 7 heating through circulating pump 11 after high-temperature water outlet 9 is extracted out, give hot water user 12, hot water user 12 used water at low temperature or the new water that replenishes return in the heat exchanger tube 7 through water at low temperature import 10 and are reheated, and make total system constitute hot-water return.
In order further to improve the heat exchanger effectiveness of this hot water unit, the modified and reinforced heat-transfer pipe of heat exchanger tube 7 best using plasmas.
In order to be satisfied with various hot water users' instructions for use, this hot water unit can provide different types of hot water simultaneously, and at this moment heat exchanger tube 7 can be pre-installed two groups or more, so that be connected with the heating system of different purposes.
In order further to improve the heat absorption capacity of heat exchanger tube 7 again, preferably the fixed installation heat absorption helps sheet on heat exchanger tube 7.
