Description

Smoke eliminator
Technical field
The invention belongs to field of environment protection, particularly a kind of smoke eliminator.
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) directly drain 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 smoke eliminator, overcome above-mentioned shortcoming, install simple; floor space is little, not only economy but also practical, is conducive to processing 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 smoke eliminator, comprise the horizontal air inlet pipe be communicated with successively from down to up successively, vertical filter pipe, transverse row tracheae and exhaust chimney, be provided with activated carbon filter layer in vertical filter pipe, activated carbon filter layer comprises left side activated carbon filtration plate and right activation charcoal filter; Left side activated carbon filtration plate and right activation charcoal filter from top to bottom interleaved are also located in the arranged on left and right sides of corresponding vertical filter pipe madial wall respectively; Horizontal exhaust tube wall is provided with spraying ventilating device; 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; Discharge outlet is provided with bottom exhaust chimney.
Beneficial effect of the present invention is as follows: 1, comprise the horizontal air inlet pipe be communicated with successively from down to up successively, vertical filter pipe, transverse row tracheae and exhaust chimney.Horizontal air inlet pipe and vertical filter pipe, transverse row tracheae and exhaust chimney perpendicular to one another, the waste gas produced after fired coal combustion passes through horizontal air inlet pipe, vertical filter pipe, transverse row tracheae and exhaust chimney successively, form the two horizontal two perpendicular paths alternately connected, anyhow unhurried current is formed in turning point place at every next, when preventing waste gas from pouring in pipeline, because pressure goes out the defect of exhaust chimney too greatly and fast, each turning point all can slow down the flow velocity of air-flow, the exhaust dwell time is in the duct increased, the filterability of device is increased.
2, be provided with activated carbon filter layer in vertical filter pipe, activated carbon filter layer comprises left side activated carbon filtration plate and right activation charcoal filter; Left side activated carbon filtration plate and right activation charcoal filter from top to bottom interleaved are also located in the arranged on left and right sides of corresponding vertical filter pipe madial wall respectively.After waste gas enters vertical filter pipe, run between the upper and lower every the left and right activated carbon filtration plate be arranged alternately, activated carbon filtration plate forms the laddering stop of one deck, one deck to waste gas, most of dust in waste gas are kept off by the activated carbon filtration plate resistance of ground floor, small part dust enters the activated carbon filtration plate of the second layer along with waste gas and is kept off by the second activated carbon filtration plate resistance, the dust of few part is only had then to enter lower one deck activated carbon filtration plate or more lower one deck activated carbon filtration plate, after said process, dust is temporarily adsorbed in the activated carbon filtration plate of each layer, and after toxic emission stops, most of dust (dust on the activated carbon filtration plate of mainly ground floor and the second layer) is according to Action of Gravity Field, dust drops and is gathered in the bottom of vertical filter pipe, the number of plies of activated carbon filtration plate is decided according to the actual requirements.
Meanwhile, waste gas pours in layer upon layer activated carbon filtration plate and filters, and most of impurity in waste gas is cleaned; And one deck, layer of active carbon filter also form temporary stop to waste gas, delayed the time that waste gas is got rid of, improve strainability, active carbon itself has the function being absorbed with poisonous gas, so more add the cleannes of waste gas simultaneously.
3, horizontal exhaust tube wall is provided with spraying ventilating device.When waste gas is after the first round filters, pour in transverse row tracheae, now there is the higher problem of temperature in waste gas after assembling in a large number, and spraying ventilating device can carry out the cooling of the first round to horizontal exhaust tube wall, suitably reduces the gas in transverse row tracheae; And carry out the best results of first round cooling measure herein, if arrange spraying ventilating device in vertical filter pipe, cold water is when vertical filter pipe stays downwards, and cold water heat absorption can become hot water gradually, is unfavorable for cooling.
4, 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.Waste gas after first round purification, finally enter into exhaust chimney, exhaust chimney interior is similar with vertical filter pipe, the pre-spraying ventilating device of flue gas and flue gas spray desulfurizer are located on two support plates of left and right 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 of waste gas, make waste gas reach discharge standard, be finally discharged in air, protect environment.
Further, slagging-off valve is provided with bottom described vertical filter pipe.Dust is finally gathered in the bottom of vertical filter pipe, and the setting of slagging-off valve conveniently can carry out deslagging process.
Further, described vertical filter pipe is provided with dust-break filter plate, between the mouth of pipe that horizontal air inlet pipe is located at by dust-break filter plate and activated carbon filter layer.Dust-break filter plate improves the effect that vertical filter pipe stops dust.
Further, the pre-spraying ventilating device of flue gas and flue gas spray desulfurizer are equipped with shower nozzle.Shower nozzle increases the coverage of spray equipment, increases spraying effect.
