Description
Technical field
The utility model relates to industrial smoke UTILIZATION OF VESIDUAL HEAT IN field, and concrete system utilizes a kind of modular construction of the high-temperature flue gas water-heating device of industrial furnace discharging.
Background technology
In industry and energy conservation technology of civilian emission reduction tasks, the effectively actively utilization of waste heat and used heat is a worth content of paying close attention to energetically and having the potential to be tapped all the time.For example, have an appointment 15～25% heat energy of general gas fired-boiler institute burnt fuel enters atmosphere by flue gas, the gas fired-boiler exhaust gas temperature of some model is 200～250 ℃, be provided with or installed additional the gas fired-boiler of economizer, the smoke evacuation heat-energy losses can reduce about 5～8%, but exhaust gas temperature is also about more than 150 ℃.For atmospheric temperature, the waste heat that does not utilize of this part flue gas has still accounted for more than 10% of fuel heat that enters.Under the condition of technology and economy permission, should consider to recycle as far as possible.Meanwhile, evaporate after contained humidity absorbs the latent heat of vaporization in the air of fuel and confession combustion in combustion process, and be present in the flue gas with the water vapour form, condensation in addition, reclaim the latent heat of vaporization, then the complementary energy recovery is more thorough, shows as and has further improved boiler thermal output, also further improves the pollution of smoke evacuation to environment.
In industrial production enterprise and other big-and-middle-sized Architectural Equipments, fuel oil or gas-operated thermal bath facility give off the middle low-temperature flue gas that contains a certain amount of steam in a large number, are destruction infringements to environment not only, cause the significant wastage of the energy equally.How this part waste heat effectively being utilized is one of practical means of energy-saving and emission-reduction enforcement.Employing direct contact type flue gas cool-down dehumidification energy saver effectively absorbs for waste heat and utilization provides reliable approach, this device is similar to vertical absorption tower, the flue gas that temperature is high enters the absorption tower from a side, discharge from opposite side, the cold water that the top is sprayed by spray equipment, by in the absorption tower with the combining of the high flue gas of temperature, " shower ", the a large amount of waste heats in the flue gas have been absorbed, water droplet temperature raises, bottom on the absorption tower is gathered, become the hot water that can be used, such low temperature exhaust heat has use occasion widely, such as the workshop factory building, the heating of hospital and big-and-middle-sized industry or commercial building facility, or green house of vegetables, the heat supply in fish pond or swimming pond or the like.
The structure of the spray equipment of prior art is fairly simple, usually adopt especially structure as bathing, be commonly called as " shower nozzle ", the side is watched triangular in shape, water inlet above, offer a large amount of apopore water outlets sprays on the following lower panel, sometimes in order to adapt to the inner major diameter of spray, dispose a plurality of " shower nozzle " shower nozzle up, generally install one in the center, outwards be by the center and dispose a circle radially, so apparatus structure is simple, the face that distributes is bigger, the water droplet of ejection can directly contact with high-temperature gas and absorb heat, has obtained the reduction flue-gas temperature, improves the purpose of water temperature, however, the key problem in technology of raising heat exchanger effectiveness is to consider best liquid-vapour ratio, strengthen the contact-making surface of spray water droplets and flue gas and reduce drag losses.Analyze each triangle " shower nozzle " structure of prior art, cooling water enters " shower nozzle " inside from the top pipeline, simple circular hole from " shower nozzle " flows out downwards again, water droplet is bigger, sometimes water pressure fluctuations, flue-gas temperature changes, and device lacks adjustable mechanism and adaptability to changes, so the ability and the efficient that absorb the high-temperature flue gas heat are restricted.
Therefore, be necessary spray equipment is done further to improve, improvement improves the efficient of its heat absorption heat release.
Summary of the invention
The purpose of this utility model, plan provides the structure-improved of a kind of absorption tower spray equipment, improves the structure of prior art " shower nozzle ", the refinement fogdrop diameter, along with the difference of hydraulic pressure can be regulated voluntarily, guarantee that water droplet has more constant atomizing diameter, improve the heat-transfer effect of spray equipment.
