Description
Technical field
The present invention relates to the improvement of a kind of heating plant and method, particularly a kind of direct-fired hot gas with do not fire solution and directly contact the heat engine that carries out heat-shift and the improvement of method.
Background technology
Boiler and HVAC industry are thought: the flue-gas temperature of boiler or hot water machine outlet flue drops to below the dew point, can reach more than 95% by higher calorific value (HHV) computing system efficient, can reach more than 100% by Lower heat value (LHV) computational efficiency; Vapour latent heat in the smoke evacuation just can reclaim below 60 ℃.At present existing extreme misery formula boiler or hot water machine are that hot gas directly contacts heat-shift with water in the innovation and creation, though energy-saving effect improves, what adopt is that the single-stage single chamber directly contacts and carries out heat-shift, and be single be media with water.Above-mentioned heating plant and method be as will satisfying the requirement (70 ℃ or more) of user to higher heat supply temperature, reaches below the dew point with regard to the temperature of the outlet flue flue gas that is difficult to descend, and improves energy-saving efficiency again thereby limited; Reach below the dew point if reduce the temperature of outlet flue flue gas in order to improve energy-saving efficiency, just be difficult to satisfy the requirement (70 ℃ or more) of user higher heat supply temperature.Moreover, be media with water, under atmospheric condition, its highest heat supply temperature that provides is no more than 100 ℃, is difficult to satisfy the user to system vapour, refrigeration or the demand of other higher heat supply temperature.
Summary of the invention
The present invention has overcome deficiency of the prior art, the improvement of a kind of heating plant and method is provided, the outlet flue flue-gas temperature of heat engine is reached still can satisfy the demand (70 ℃ or more) of user below the dew point higher heat supply temperature, raise the efficiency, energy savings, and simple in structure, cost is lower.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions: start-up control device, fuel oil or combustion gas are by burner, and spraying into lights a fire in the combustion chamber fully burns.High-temperature gas after the burning directly is admitted to high heat-exchanging chamber, do not fire solution downwards from high heat-exchanging chamber top solution spraying device spray, high-temperature gas with do not fire solution and in high heat-exchanging chamber, directly contact and carry out heat-shift, heated pyrosol falls in the liquid bath that concentrates on high heat-exchanging chamber bottom, be used for producing for the user from the liquid outlet extraction by liquid pump, (user not only is used for heating in life, hot water etc., and be used for freezing, system vapour etc., need the hydrothermal solution more than 100 ℃, select salts solution for use, lithium bromide wherein, barium chloride, calcium chloride water all can), recycle after inlet is got back in the machine; The hot gas that high heat-exchanging chamber is lowered the temperature enters low heat-exchanging chamber again, water from low heat-exchanging chamber upper water spray thrower spray downwards, the hot gas of being lowered the temperature directly contacts in low heat-exchanging chamber with water once more and carries out heat-shift, heated water falls in the tank that concentrates on low heat-exchanging chamber bottom, be used for heating, hot water, preheated air etc. from the delivery port extraction for user's production, life by water pump, recycle after water inlet is got back in the machine.Here existing heat exchange has the matter exchange again, and water is to recycle in pyrosol and the machine.Thereafter the flue gas of clean low temperature (dew point is following) discharges by outlet flue.Adopt resistant material such as manufacturings such as stainless steel, fluorine-containing coat material in the machine.Heat engine adopts Automatic Control.
The invention has the beneficial effects as follows: energy-conservation, economical, safety, environmental protection.
1., significant energy savings.Thermal efficiency long-term stability when particularly using gas fuel, absorbs the steam that produces when burning more than 90%, and energy-saving effect is obvious especially.Can reach 95% by higher calorific value (HHV) computational efficiency, can reach 100% by Lower heat value (LHV) efficient.
2., manufacturing is simple, cost is lower, can produce remarkable economic efficiency.Water is cooked media, and is cheap, and manufacturing cost is lower: do media with salts solution, cost increases, but because of the function expansion, integrated cost is still lower.The heat engine volume is little, in light weight, safety, environmental protection, approaches to compare to the long-range heating network in user's heat supply and city to reduce construction, maintenance fund, and heat waste is less, reduces cost of business operation.
3., all do not have airtight pipeline in the machine, inside is no more than atmospheric pressure, can not blast, and belongs to safety product.
4., two kinds of differences do not fire solution independent loops operation separately in machine, all do not produce and leak, and regularly focus on, and do not pollute the environment, and belong to environment-friendly products.
