Description

But the water-gas environment-protection boiler of desulphurization energy-saving

Technical field

The utility model belongs to the improvement of boiler structure, but the water-gas environment-protection boiler of desulphurization energy-saving particularly.

Background technology

Present various energy-saving, environmental protection boiler is of a great variety, the stove of most of first usefulness or boiler are for only filtering the boiler of carbon black, flue dust, but still contain in the middle of the flue gas of discharging at the totally back oxysulfide SOx (mainly being sulfurous gas) that produces of fired coal combustion, SOx floats in the atmospheric layer after discharge, produce the higher sulfuric acid of acidity with water vapor (cloud) chemical combination in the atmospheric layer, finally can form acid rain landing on the ground, cause animals and plants to be on the hazard and injure.

The utility model content

But the purpose of this utility model is to provide a kind of water-gas environment-protection boiler of desulphurization energy-saving, and is not only more energy-conservation and economize on coal, and makes flammable semiwater gas desulphurizing, reduces atmospheric pollution.

But order of the present utility model is achieved in that a kind of water-gas environment-protection boiler of desulphurization energy-saving, comprise body of heater, coal filling hole is being set on the body of heater, cooperate the fire grate that is installed in bottom in the body of heater body of heater inner chamber to be divided into burner hearth that is on the fire grate and the inlet air plenum that is positioned under the fire grate, the inlet air plenum bottom is being provided with ash output hole, on the body of heater perisporium water jacket is being set, its lower port of the smoke exhaust pipe that is provided with on the furnace body outer wall is communicated with burner hearth by the smoke outlet that is provided with on the body of heater shell wall, the supporting leg that supports body of heater is being set on the body of heater bottom, water jacket is communicated with steam guiding tube by the steam outlet that is provided with on its outer wall, blower fan is communicated with blast pipe by its air outlet, steam guiding tube is communicated with blast pipe by its steam drain, and the blast pipe the other end is communicated with inlet air plenum; Burner hearth is communicated with the water-gas intake line by the opening on its body of heater upper end perisporium; The lateral partitions that is provided with in the water tank is divided into the water tank cavity in thermal cycling water tank that is positioned on the lateral partitions and the desulfurization water tank that is positioned under the lateral partitions, be equipped with lime aqueous solution in the desulfurization water tank, primary steam condensation tube that is equipped with in the water tank and secondary steam condensation tube vertically cooperation intert on lateral partitions affixed, this lateral partitions makes the upper end of primary steam condensation tube and the sealing of secondary steam condensation tube all place the thermal cycling water tank, and the lower end that makes primary steam condensation tube and secondary steam condensation tube opening all is under the lime aqueous solution liquid level in the desulfurization water tank, its the other end outlet of above-mentioned water-gas intake line stretches under the primary steam condensation tube inner chamber bottom and the lime aqueous solution liquid level of submerging, the primary steam condensation tube connects the tracheae of crossing that is arranged in the thermal cycling water tank by the venting hole of its upper end perisporium setting, crosses the tracheae the other end and is communicated with the secondary steam condensation tube by the air inlet port that secondary steam condensation tube upper end perisporium is provided with; The one end import of water-gas delivery conduit stretches to secondary steam condensation tube inner chamber bottom and is positioned on the lime aqueous solution liquid level, and the outlet of the water-gas delivery conduit the other end is connected with the gas-cooker inlet end.

The utility model principle of work is, the introduction (as firewood) that will work the effect of igniting earlier adds burner hearth through the body of heater coal filling hole, the particulate coal that will be mixed with powder coal again adds that (mass content of powder coal is no more than 30% within the burner hearth, the coal particle diameter of particulate coal is generally about 3cm-5cm), on the introduction, meanwhile starting blower fan feeds air in the burner hearth (water should be injected in the water jacket in advance) through inlet air plenum and fire grate, make coal charge that no flame oxidation thermopositive reaction take place by lighting introduction, the heat that coal charge discharged conducts to water jacket by the body of heater internal perisporium, the suction function that water vapor that gasification back, water boiling back in the water jacket produces is produced in blast tube because of self pressure and blower fan air-supply, the air mixed that enters blast tube and blower fan introducing through steam guiding tube together enters burner hearth through inlet air plenum and fire grate by coal charge, airborne oxygen and particulate state coal charge generation exothermic oxidation reaction that blower fan is introduced, make coal charge be in bright red heat state, because the high temperature when being in the particulate state coal charge oxidizing reaction on the fire grate can make water vapor generation scission reaction over half, resolve into hydrogen and oxygen, it (is SOx that thioneine high temperature oxygen in the while coal charge changes into oxysulfide, mainly be sulfurous gas), contain also hydrogen together of the uncracked water vapor of oxysulfide gas and part to produce after the cracking, oxygen mixture (abbreviation knallgas) at first enters lime aqueous solution in the desulfurization water tank of water tank bottom by the water-gas intake line, correspondingly, the knallgas that contains oxysulfide gas is during by lime aqueous solution, lime in the lime aqueous solution and the oxysulfide generation chemical reaction in the knallgas, make oxysulfide generate the throw out calcium sulfate precipitation at the bottom of the desulfurization water tank case, and remove part sulphur by hydrogen, the water-gas that oxygen and water vapor are formed floats to filtering water vapor in the primary steam condensation tube with bubble in form, owing to fill recirculated water in the thermal cycling water tank, a part of water vapor wherein is condensate on the primary steam condensation tube inwall by amount in floating-upward process, the drop of forming after the condensation gathers big back and crashes into fusion with it in the Wingdale solution because of gravity carries over primary steam condensation tube inwall, remaining water vapor and knallgas are again by crossing the water vapor that tracheae enters secondary steam condensation tube filtering remainder, remaining another part water vapor is condensate on the secondary steam condensation tube inwall equally, the drop of forming after the condensation gathers and drops and incorporate in the Wingdale solution because of gravity carries over secondary steam condensation tube inwall equally after big, simultaneously, rest parts oxysulfide back in entering the secondary steam condensation tube is entering before the one end import of water-gas delivery conduit and to generate precipitate with the lime aqueous solution reaction at the bottom of the desulfurization water tank case, so far, basically desulfurization and remove the knallgas-hydrogen of water vapor and oxygen enters the gas-cooker heat release of igniting once more by the water-gas delivery conduit again and is combined to water, do not have other resultant, do not pollute surrounding environment and atmosphere.

In addition, when if the mass ratio of water is not enough in the lime aqueous solution, can be supplemented in the desulfurization water tank lime aqueous solution by the drop that condenses on primary steam condensation tube and the secondary steam condensation tube inwall,, only need add lime in addition and get final product so need not artificial recharge in the desulfurization water tank in addition.Above-mentioned again principle analysis can learn, the utility model is not only more energy-conservation and economize on coal, and makes flammable semiwater gas desulphurizing, reduces atmospheric pollution.
