Description
Technical field
The invention belongs to field of environment protection, particularly a kind of waste gas double purified device.
Background technology
Along with the fast development of science and technology, the attention of people to environment is also more and more higher, and the discharge standard of environment is also more and more stricter.Few places still adopts burning coal to exchange the mode of heat energy for, containing a large amount of pollutants such as sour gas (as sulfurous gas), dust, heavy metal in the flue gas of fired coal combustion, therefore needs to carry out purification control to flue gas.
At present, people use maximum in flue gas desulfurization: absorb the sour gas in flue gas by absorbent slurry.The flue gas self-temperature produced due to fired coal combustion is higher, and the gas componant more complicated in flue gas, and have higher requirement to the temperature tolerance of desulphurization plant, corrosion resistance, its desulfuration efficiency is also poor.
And dust, unfiltered flue gas (containing poison gas) are directly discharged into air, the demand of not only discontented sufficient environmental protection, also produces directly harm to human body.
Summary of the invention
The object of the present invention is to provide a kind of waste gas double purified device, overcome above-mentioned defect, install simple; floor space is little, not only economy but also practical, is conducive to disposing the poisonous gas and dust that produce in fired coal combustion process; efficiently solve exhaust pollution problems, protect atmospheric environment.
For achieving the above object, technical scheme provided by the invention is as follows: a kind of waste gas double purified device, comprises the air inlet pipe, deduster, blast pipe and the exhaust chimney that are communicated with successively; Deduster inside is provided with dedusting baffle plate and lower dedusting baffle plate, and described upper dedusting baffle plate and lower dedusting baffle interval are crisscross arranged, and upper dedusting baffle plate is suspended in deduster upper end inwall, and described lower dedusting baffle plate is fixed on deduster lower end inner wall; Exhaust tube wall is provided with spray equipment; The madial wall of exhaust chimney is provided with upper and lower staggered left supported plate and right supported plate, and left supported plate is provided with the pre-spraying ventilating device of flue gas, and right supported plate is provided with flue gas spray desulfurizer; The pre-spraying ventilating device of flue gas and flue gas spray desulfurizer are equipped with shower nozzle; Discharge outlet is provided with bottom exhaust chimney; Wherein, slagging-off valve is provided with bottom deduster; Slagging-off valve inner face offers groove, and groove is provided with echelette; Slagging-off valve one end and deduster bottom-hinged, the other end is provided with buckle.
Echelette is the one of active infrared correlation, adopt multi beam infrared light correlation, transmitter sends infrared light to receiver in " low frequencies, time-division are detected " mode, any adjacent two bundles that transmitter sends have been blocked with glazed thread more than 30ms once have personnel or object, receiver is output alarm signal immediately, when block wherein Ray Of Light time, alarm can not output alarm signal.
Beneficial effect of the present invention is as follows: 1, deduster inside is provided with dedusting baffle plate and lower dedusting baffle plate, described upper dedusting baffle plate and lower dedusting baffle interval are crisscross arranged, upper dedusting baffle plate is suspended in deduster upper end inwall, and described lower dedusting baffle plate is fixed on deduster lower end inner wall.Waste gas is by entering into deduster after air inlet pipe, and through super-interval and after the upper dedusting baffle plate be crisscross arranged and lower dedusting baffle plate, in waste gas dust by the upper dedusting baffle plate of alternating floor between one deck and lower dedusting baffle plate stop the quantity of upper dedusting baffle plate and the lower dedusting baffle plate (be decided according to the actual requirements quantity), on the upper dedusting baffle plate that dust is stacked on deduster or lower dedusting baffle plate, temporarily and waste gas isolate; Meanwhile, upper dedusting baffle plate and lower dedusting baffle plate form passage one on the other, add the time of waste gas through deduster, make the dust in waste gas fully by upper and lower dedusting baffle, serve the effect removing dust.
2, exhaust tube wall is provided with spray equipment.When waste gas pours in blast pipe after first round deduster filters, now waste gas forms higher temperature through a large amount of gathering, and spray equipment carries out the cooling of the first round to exhaust tube wall, suitably reduces the temperature of gas in blast pipe.
3, the madial wall of exhaust chimney is provided with upper and lower staggered left supported plate and right supported plate, and left supported plate is provided with the pre-spraying ventilating device of flue gas, and right supported plate is provided with flue gas spray desulfurizer; The pre-spraying ventilating device of flue gas and flue gas spray desulfurizer are equipped with shower nozzle; Discharge outlet is provided with bottom exhaust chimney.Waste gas after first round udst separation, finally enter into exhaust chimney, exhaust chimney interior is with deduster similar (being all that layer and layer are arranged alternately), the pre-spraying ventilating device of flue gas and flue gas spray desulfurizer are located on the plate of the left and right sides respectively, first undertaken second by the pre-spraying ventilating device of flue gas takes turns cooling to waste gas, then desulfurization process is carried out by flue gas spray desulfurizer again, subsequently again by the cooling of next group flue gas pre-spraying ventilating device (quantity of left supported plate and right supported plate and the visual actual conditions of the quantity of the pre-spraying ventilating device of supporting flue gas and flue gas spray desulfurizer are arranged), circulation like this, realize the filtration to waste gas, waste gas is made to reach discharge standard, finally be discharged in air, protect environment, accordingly, supportingly bottom exhaust chimney discharge outlet is provided with.
4, wherein, slagging-off valve is provided with bottom deduster; Slagging-off valve inner face offers groove, and groove is provided with echelette; Slagging-off valve one end and deduster bottom-hinged, the other end is provided with buckle.Groove forms dust collect plant, conveniently accumulates dust, and also prevents echelette directly malfunctioning by airflow scouring, after air-flow pours deduster, directly skips over also up walking (because of the existence of groove, air-flow and echelette directly stagger) of echelette above; If in groove, dust is too much simultaneously, when covering echelette completely, receiver is output alarm signal immediately, reminds operator, and deduster internal dust needs to remove too much.
Further, described slagging-off valve is provided with the buzzer be connected with the receiver of echelette.Because echelette is arranged on deduster inside, therefore buzzer is connected with the receiver of echelette.
