Description
Technical field
The utility model relates to a kind of coal heat energy and utilizes system, particularly a kind of high-efficient energy-saving environment friendly heat energy utilization system taking fine coal as fuel.
Background technology
Coal is the topmost primary energy of China always, is subject to the conditionalities such as china natural resources, and the status of coal in China's primary energy is by long term maintenance.The especially middle-size and small-size industrial chain boiler of Industrial Boiler is that China's consumption coal is maximum, one of the widest equipment distributes.The existing coal-fired industry chain furnace ubiquity thermal efficiency is low, the problem that pollutant emission exceeds standard.Although fuel oil, gas boiler environmental protection and energy saving, fuel cost is very high, and enterprise is difficult to bear.Under energy-saving and emission-reduction historical background, coal is converted into coal gas and sends into boiler combustion utilization, both having maintained the economy taking coal as fuel, and brought into play again that gas fired-boiler efficiency of combustion was high, nitrogen oxides pollution discharges few advantage, is that coal cleans one of direction of utilization.Existing fixed bed coal gas producer is taking lump coal as fuel, compared with fine coal, lump coal price is higher, lump coal fancy price has limited the application of gas generator at boiler industry, and existing boiler then coal can produce the pollutants such as a large amount of sulfur dioxide, nitrogen oxide and flue dust, environment is brought to adverse effect.
Summary of the invention
The technical problems to be solved in the utility model is for the deficiencies in the prior art, proposes a kind of high-efficient energy-saving environment friendly heat energy utilization system taking fine coal as fuel.This system not only can realize fine coal for fixed bed coal gas producer, but also the flue gas pollutant that can make boiler discharge greatly reduces, environmental protection more.
The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of high-efficient energy-saving environment friendly heat energy utilization system taking fine coal as fuel, comprise moulded coal process equipment, the output of moulded coal process equipment connects two-part fixed bed coal gas producer, the epimere outlet of two-part fixed bed coal gas producer exports with hypomere the input that is connected respectively heating gas desulfurizer through dry method decoking equipment with dry-type dedusting equipment, the output of gas desulfurizer connects boiler, the exhanst gas outlet of boiler is connected final heat exchanger group through the hot flue gas desulfur device of dry method with the hot fume dust remover of dry method.
The technical problems to be solved in the utility model can also be come further to realize by the following technical programs, and the exhanst gas outlet of described boiler is connected final heat exchanger group through the hot flue gas desulfur device of dry method with the hot fume dust remover of dry method.
Compared with prior art, the utlity model has following technique effect: the utility model replaces lump coal as raw material taking fine coal, through the gasification of two-part fixed bed coal gas producer, is gaseous fuel by solid fuel conversion, reduce formation of nitrogen oxides, reduced boiler soot emission simultaneously; Desulfurizer and dust arrester are set in system, can reduce the discharge of sulfur dioxide and flue dust.The utility model can be than routine the saving coals from boiler taking lump coal as fuel approximately 20%, the coal than routine taking lump coal as raw material turns the equipment of gas, approximately saves 25% expense, more economically, environmental protection, is more conducive to promote.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model system.
Detailed description of the invention
A kind of high-efficient energy-saving environment friendly heat energy utilization system taking fine coal as fuel, comprise moulded coal process equipment 1, the output of moulded coal process equipment connects two-part fixed bed coal gas producer 2, the epimere outlet of two-part fixed bed coal gas producer 2 exports with hypomere the input that is connected respectively heating gas desulfurizer 5 through dry method decoking equipment 3 with dry-type dedusting equipment 4, the output of heating gas desulfurizer 5 connects boiler 6, and the exhanst gas outlet of boiler 6 is connected final heat exchanger group 9 through the hot flue gas desulfur device 7 of dry method with the hot fume dust remover 8 of dry method.
Adopt device of the present utility model, can realize the high-efficient energy-saving environment friendly heat energy utilization taking fine coal as fuel, its method comprises the steps:
A, first fine coal is inputted to moulded coal process equipment 1 and made moulded coal, then moulded coal is converted into upper and lower two sections of hot dirty gas by two-part fixed bed coal gas producer 2;
B, epimere hot dirty gas is carried out to dry method decoking by dry method decoking equipment 3, hypomere hot dirty gas is carried out to dry dust removal by dry-type dedusting equipment 4 simultaneously, then the epimere heating gas after dry method decoking and the input of the hypomere heating gas after dry dust removal heating gas desulfurizer 5 are carried out to desulfurization processing;
C, by heating gas after treatment desulfurization input boiler 6 carry out burning conversion be heat energy for heat utilization equipment utilization, the flue gas producing after heating gas burning discharges.
In step c, the flue gas producing after heating gas burning first takes off flow processing and dust removal process by the hot flue gas desulfur device 7 of dry method and the hot fume dust remover 8 of dry method, then inputs final heat exchanger group 9 and carry out heat energy utilization, after enter atmosphere.
Using method of the present utility model, fine coal is sent into moulded coal process equipment 1, by two-part fixed bed coal gas producer 2, moulded coal is converted into, lower two sections of hot dirty gas, epimere hot dirty gas carries out dry method decoking through dry method decoking equipment, hypomere hot dirty gas carries out dry dust removal through dry-type dedusting equipment 4, then enter heating gas desulfurizer 5 respectively or after mixing, heating gas after desulfurization enters boiler 6 and burns, the high-temperature flue gas that boiler is discharged is after the hot flue gas desulfur device 7 of dry method and the hot fume dust remover 8 of dry method, after 9 heat exchange of final heat exchanger group, realize qualified discharge.
Desulfurizer in the utility model using method is to select in heating gas desulfurizer 5 and the hot flue gas desulfur device 7 of dry method, but also both all select.
During taking fine coal as fuel, for ensureing the requirement of fixed bed coal gas producer fuel granularity, be provided with moulded coal process equipment, fine coal be processed into the block moulded coal that meets gas generator coal standard.
In order to ensure systematic economy performance, gas generator should be selected two-part structure, extracts the tar of by-product.Two stage type gas generating furnace gas in upper segment is relatively many containing tar, in gas in upper segment outlet, dry method decoking equipment is set.
Produce heating gas sensible heat in order to make full use of gas generator, coal gas enters stokehold and water film dedusting etc. is not set reduces the device of heat utilization rate.And the insulation of reinforcement to equipment, pipeline etc.
For avoiding boiler flue gas sulphur dioxide discharge to exceed standard, reduce flue gas dew point temperature, reduce boiler exhaust gas heat loss.In coal gas stage, flue gas stage, desulfurizer all can be set.Coal gas stage desulfurization mainly removes hydrogen sulfide, and flue gas stage desulfurization mainly removes sulfur dioxide.
Moulded coal process equipment, two-part fixed bed coal gas producer, dry method decoking equipment, dry-type dedusting equipment, heating gas desulfurizer, boiler, the hot flue gas desulfur device of dry method, the hot fume dust remover of dry method, final heat exchanger group and necessary safety guard that the utility model adopts all can directly be buied from the market.
