Description
Technical field
This utility model belongs to field of chemical equipment, more particularly, it relates to a kind of enamel reaction still produces and uses coal-fired steam boiler system.
Background technology
The function of coal-fired steam boiler is i.e. as the energy with coal, and water adds the steam being thermally generated certain pressure.The steam that coal-fired steam boiler produces is in chemical industry equipment, frequently as the heating energy source of reactor.Coal-fired steam boiler uses coal as fuel at stove chamber inner combustion, thus the heat of release is heated the water in body of heater, makes the water in body of heater be converted into steam.Verticle coal-burning stem boiler generally comprises body of heater, is provided with the burner hearth as combustion heat release district at lower portion of furnace body, is provided with along burning coal-feeding door, anti-burning coal-feeding door and shoot door at described burner hearth, and described body of heater is provided with the parts such as chimney, steam (vapor) outlet, relief valve.Fire coal, at stove chamber inner combustion, produces and discharges heat and heat body of heater, and the cigarette of generation passes through smoke stack emission, and the coal ash of residual is then cleared up at shoot door.The flue gas that coal-fired steam boiler produces in running is a kind of polluter, because the dust produced when burning containing coal in flue gas and SO2Deng gas, being directly discharged in air if not carrying out process, environment certainly will be polluted and human body is damaged, and coal ash is easily piled up in chimney, is not easily cleaned, causes obstruction.Therefore, the process to coal-fired steam boiler flue gas increasingly comes into one's own.Additionally, containing part steam in flue gas, take away the partial heat of coal combustion, reduce the utilization rate of calory burning.
In addition, enamel reaction still is as reaction vessels, during the steam reacting by heating that coal-fired steam boiler produces, along with the operation of agitating device, and the carrying out of reaction, tail gas can be produced in tank body, these tail gas contain composition that is harmful and that pollute environment, and the tail gas that reaction produces is substantially and is directly discharged in air, not only pollutes environment by existing enamel reaction still, also make Workshop Production ecological deterioration, producers' health is worked the mischief.And, in workshop, the most all there is multiple enamel reaction still, if each reactor individually carries out vent gas treatment, floor space is big, and efficiency is low, and production cost is high.
Prior art, existing multiple dust-removing desulfurating apparatus comes out, but existing dust-removing desulfurating apparatus general structure is more complicated, investment is relatively big, more with water, thus promotes and have difficulties, and especially for middle-size and small-size coal-fired steam boiler, promotes increasingly difficult；Furthermore, some apparatus functions are single, are only capable of dedusting or desulfurization, cause a lot of medium and small boiler only to join dust arrester, are unworthy of desulfurizer, or are mounted with that desulfurizer does not uses.nullAs China Patent Publication No. is: CN 102135275 A，Publication date is: the patent documentation on July 27th, 2011，Disclose a kind of smoke purification energy-saving device of coal-fired steam boiler，It is, at former coal-fired steam boiler chimney outlet, utilidor is installed，It is connected with thermal conductive metal pipe again and introduces in insulating cement pond，By cool water heating in pond，Then it is passed through equipped with in the plastic barrel of water fog generator after its dust-filtering being fallen by plastics dust cartridge filter，It is made fully to react with water smoke with the harmful gas of sulfur oxide and carbon monoxide，Generate at the bottom of dilute sulfuric acid and dilute carbonic acid mixed liquor sink to tin and reclaimed，Reach dedusting、The purpose of removing and harmful gas，But this apparatus structure is complex，Invest bigger，Flue gas holdup time in flue is longer，Cause circulating the most smooth，On the one hand in causing burner hearth, coal combustion efficiency reduces，On the other hand flue gas can fall discharge from burner hearth.
nullAnd for example，China Patent Publication No. is: CN 202868716 U，Publication date is: the patent documentation on April 10th, 2013，Disclose a kind of coal-fired steam boiler that can be automatic pressure-controlled，There is floss hole and air inlet，Floss hole is connected by pipeline air-introduced machine，Air-introduced machine is connected by pipeline chimney，Air inlet connects aerator by pipeline，Air-introduced machine connects the air-introduced machine converter for controlling air-introduced machine rotating speed，Aerator connects the blower variable frequency device for controlling blower speed，Pressure transmitter and secondary meter it is provided with on coal-fired steam boiler，Secondary meter connects air-introduced machine converter and blower variable frequency device，This utility model can be automatic pressure-controlled coal-fired steam boiler，Pressure transmitter is used to gather boiler pressure and send secondary meter to，Reach to control rotation speed of fan by secondary meter output control electric current to converter and carry out the purpose of pressure control，Solve tradition coal-fired steam boiler pressure control to waste time and energy，The problem also wasting resource，Improved method is simple，It is easy to practicality，It is greatly saved manpower and cost.But this coal-fired steam boiler does not have dust-removal and desulfurizing function, flue gas is directly discharged in air, pollutes environment and works the mischief human body.
Summary of the invention
1, problem to be solved
For the flue gas that existing coal-fired steam boiler produces contains dust and SO2Deng gas, enamel reaction still does not have tail gas treating function, the tail gas produced, the problem that these gases and dust are directly discharged in air cause environmental pollution and work the mischief human body, this utility model provides a kind of enamel reaction still to produce and uses coal-fired steam boiler system, the flue gas of coal-fired steam boiler can be purified, remove the dust in flue gas and SO2, and the tail gas producing enamel reaction still carries out centralized recovery, it is to avoid environmental pollution and human body is worked the mischief；Recycling meanwhile, it is capable to the steam in flue gas carries out condensation, reduce boiler feed water amount, improve heat utilization ratio, save the energy, this system is reasonable in design, compact conformation, it is easy to implement.
