Description
Technical field
The present invention relates to a kind of chemical industry thermodynamic apparatus of comprehensive utilization of energy, refer in particular to a kind of coal that utilizes and be the energy, be converted into the industrial production steam power, the thermodynamic apparatus of clean hot air power is applicable to the various chemical industry production environments that need steam (1.5Mpa is following) and hot-air (100-200 ℃) simultaneously.
Background technology
Steam and clean hot air are that industrial production extensively adopts the heat power kind, and traditional preparation method is to use various boiler to produce steam, obtains hot-air with special-purpose heat-exchange apparatus again.At present, the thermal efficiency of boiler can reach about 60-75%, air heat transmission equipment integrated heat efficiency can reach about 40-60, name is called " a kind of is the high-efficient hot air furnace of heat transfer medium with liquid ", the patent No. is the Chinese patent of CN97235965.6, disclosing a kind of is the high-efficient hot air furnace of heat transfer medium with liquid, and its thermal efficiency also only is 65-75%.The heat energy utilization rate is because a variety of causes restriction is difficult to further raising, both caused energy waste, increased environmental pollution again, in the today of advocating resource-conserving, environmentally friendly development model energetically, energy savings, reducing to pollute becomes reality and permanent problem.Particularly needing steam and hot-air simultaneously is in the industrial production of power, how to realize organic combination, improves the significant and huge economic benefit of heat energy utilization rate.
In order effectively to solve the deficiency of existing chemical industry thermodynamic apparatus, the technical staff is attempting steam and hot-air are combined always.Chinese patent CN94208577.9, name is called " a kind of hot blast, two boilers of steam ", disclose a kind of hot blast, two boilers of steam, this boiler is made up of boiler hot blower fan and shell, puts a flue in the furnace shell, fire grate is wherein horizontal, place a dividing plate on the flue, evenly be placed with heat-transfer pipe on it, a dividing plate is arranged on the heat-transfer pipe, there is a water ash bin flue lower end, makes it constitute air-heater.Shell is placed in outside it, and bottom and water ash bin fuse, and opens a water inlet, sewage draining exit under the shell, and center of top has a throat, and a boiling water mouth is arranged at top, and the water level meter is equipped with in the outside, and automatic blow off valve is equipped with at the top, has steam port, is equipped with the film safety valve on it.The air blast interface passes shell and furnace shell is communicated with flue.Chinese patent CN02283920.8, name is called " the hot all-in-one oven of a kind of vapour of the hot all-in-one oven of vapour ", discloses two boilers of another kind of hot blast, steam again, the steam generator upper stack that this boiler is made of heater, water supply tank etc. a heat blower.Heater is a coal, and it is made of grate, fire door, burner hearth and hearth wall, flue and chimney; Put the water spacer that annular is arranged around the hearth wall of steam generator, water spacer middle part is a burner hearth, and the hearth wall top is a heat blower.Water supply tank places the steam generator periphery, and the altitude valve door in the water supply tank is the float-type valve.The utility model is behind a stacked heat blower above the steam generator, combustion flame from bottom to top, following steam generator produces steam, top heat blower output hot blast, having solved steam and hot blast effectively need be by the technical problem of independent steam generator and hot-blast stove generation.
But above-mentioned steam and hot air boiler are vertical heater, tolerance that is produced and air quantity are because can not be very big due to the structure, can not the satisfy the demand place of atm number and air quantity, and the industrial and mineral place of chemical industry is to need a large amount of hot blasts and steam simultaneously mostly, and therefore above-mentioned method and structure is inapplicable chemical industry application.
Summary of the invention
The objective of the invention is to deficiency, particularly need simultaneously during the chemical industry of a large amount of steam and hot-air produces, the having high input of existence, the problem that energy consumption is high at existing chemical industry thermodynamic apparatus.A kind of efficient hot blast little, that energy consumption is low, vapor mixing heating power stove of dropping into is provided.
The objective of the invention is to be achieved through the following technical solutions.Adopt modularization composite structure, whole heating power stove is divided into burner module, dedusting module, steam generation module, hot-air generation module and five kinds of modules of waste heat recovery module, and each module is reasonably combined by connector forms complete efficient hot blast, a vapor mixing heating power stove again.Putting in order of its module can be burner module, steam generation module, hot-air generation module arrives the waste heat recovery module, also can be the arrangement of alternate manner.The dedusting module can be provided with between any two modules between the waste heat recovery module in burner module according to the quality of coal, also can be provided with between any two modules.Can be one or more, complete character according to coal be definite, thereby can satisfy the application of coal inferior fully.Even if make with coal inferior to be raw material, passing through reasonable disposition steam generation module, hot-air generation module, waste heat recovery module, the integrated heat efficiency of whole heating power stove is reached more than 90%, and realizing the adjustable controlled of steam generating amount, hot-air generating capacity and hot total amount, scale is optional from heat power scope 60-2000 ten thousand Kcal.Adopt hot blast, the vapor mixing heating power stove of this modularization composite structure, can choose module device according to different production environments fully, be a kind of reduced investment, efficient height, pollute less, transfer the outstanding flexibly thermodynamic apparatus of sky.Characteristics of the present invention are:
1, created combination heating power, modular mode has solved the difficult problem that traditional heat power equipment coal adaptability is poor, puppet is arranged the temperature height, big, the different heat power of heat loss repeats to be provided with, small investment, efficient height.
2, coal adaptability is strong, the extensive coal in the pass of incendivity 3000～7000kcal/kg.
3, efficiency of dust collection height, dust contained flue gas is few.
4, integrated heat efficiency reaches 90%.
5, can provide steam power, hot-air power, reduced investment, occupation of land little simultaneously.
