Description
Technical field
Oil, water, dust purification recycle device in the flue gas belong to industrial waste gas and administer with environmental protection, energy-conservation cleaning equipment and processing method field.
Background technology
Enterprise will survive, and realizes sustainable development, environmental improvement and energy-conservation be crucial; Many enterprises do not close, stop, merge and shift because of environmental protection is up to standard.What the flue gas ash removal technology generally adopted now is the cloth-bag type dedusting, and fiber bag precipitator effect for the flue gas of pure dust is very obvious; But except that dust, contain compositions such as oil, water in the present flue gas toward contact.Flue gas generally is high temperature on the one hand, and this just requires the heat-resisting quantity of cloth bag material very good, and existing domestic enterprise adopts the cloth bag of import material usually, and such cloth bag cost is very high; On the other hand, flue gas is through sack cleaner the time, and the oil in the flue gas can make dust removing effects reduction, the lost of life of cloth bag attached to the surface of cloth bag, causes the replacement cycle of cloth bag short, brings heavy financial burden to enterprise; And fume emission is not up to standard, causes the pollution of enterprise to atmospheric environment, brings certain social responsibility burden to enterprise again.
Therefore, research and development a kind of can be effectively with oil, water in the flue gas, dust purification is up to standard and the device that can recycle is very necessary.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the problem that prior art exists, provide a kind of simple in structure, can make useless fume emission up to standard, and oil, water, dust purification recycle device in the flue gas that can recycle the oil in the flue gas.
The technical solution adopted for the present invention to solve the technical problems is: oil in this flue gas, water, the dust purification recycle device, comprise sack cleaner, an air-introduced machine, first pipeline, the secondary air-introduced machine, the purification recycle device is set, No. one time air-introduced machine one end links to each other with first pipeline, the other end links to each other with the purification recycle device, purify recycle device and sack cleaner, the secondary air-introduced machine links to each other by second pipeline, the secondary air-introduced machine connects chimney, it is characterized in that: purify recycle device and comprise shell, reflecting curtain, filter baffle plate, the oil plant collection hole, the oil plant recovery tube, fuel outlet valve, the shell bottom is provided with the oil plant recovery tube, filtering baffle plate is fixed on the shell by lower supporting plate is oblique, on the hypotenuse direction of edge filtration baffle plate, reflecting curtain is installed, reflecting curtain is fixed by upper backup pad, the oil plant collection hole is set on the oil plant recovery tube, and the oil plant recovery tube is divided into the storing fuel tap.
Filter baffle plate and be fixed on the shell by lower supporting plate is oblique, the angle α that filters baffle plate and shell is 30-60 °.The effect of filtering baffle plate is that elaioleucite is dammed, and the effect of reflecting curtain is flue gas to be reflexed to next group baffle plate refilter and dam.
The filtration baffle plate is a half elliptic, and flanging is established at the top, the uniform through hole in top, the uniform pockmark in bottom.
Reflecting curtain is a half elliptic, and the half elliptic reflecting curtain is a corrugated.
Upper backup pad and lower supporting plate are herringbone.The effect of herringbone gripper shoe is with filtration baffle plate and reflecting curtain support fixation in the enclosure.
Filter baffle plate and reflecting curtain mounted in pairs, form the broken line passage.How right can be provided with.
The half elliptic reflecting curtain can also be designed to laterally zygomorphic groove shape.Or be other effective shapes of damming.
Flue gas is at first by pipeline, and an air-introduced machine enters the purification recycle device and carries out the first separation processing, reclaims; Treated flue gas enters the sack cleaner after-treatment through pipeline, enters chimney through the secondary air-introduced machine.
Operation principle
Utilize mechanics principle design, the particle in the flue gas is separated.Through the air-introduced machine pressurization, the elaioleucite in the flue gas can be got to the bottom with certain speed and filter on the baffle plate.Filter baffle plate when mounted, be welded in the shell of equipment with certain angle (30 °-60 ° at α angle), filtering baffle plate top has the equally distributed through hole that varies in size, when flue gas passes through, have the elaioleucite of part to be dammed retaining on the filtration baffle plate, and drippage go down; In the bottom of filtering baffle plate some cellular apertures (not penetrating) are arranged, can the oil that keep off effectively be dammed, the oil droplet that gets off that dammed can up move at the effect lower edge of wind-force filtration baffle plate, oil droplet moves to filtration baffle plate top and can drip through through hole, on the hypotenuse direction of edge filtration baffle plate the top reflecting curtain is installed, the surface of reflecting curtain is a bellows-shaped; Flue gas arrives the top reflecting curtain under through the effect in power after the reflecting curtain, the oil droplet that drips is pooled to oil plant recovery holes place under the effect of the reaction force of top reflecting curtain and self gravitation, flow to again in the oil plant recovery tube, finally flow into oil groove.Through the damming and filters of such multilayer baffle plate, oily effectively being removed in the flue gas, according to the difference of engineering actual conditions, the varying in size of equipment, the number of plies of filtration is difference thereupon also.Flue gas after the oil purification carries out dedusting through sack cleaner again, finally reaches the purpose that purifies flue gas.
Compared with prior art, oil, water, dust purification recycle device and method had in the flue gas of the present invention
Beneficial effect is: device has simple in structure, and processing and fabricating is easy, cost is low.Contained oil has the quilt more than 98% to dam to get off in the treated flue gas, the oil saver of the oily access to plant bottom of getting off of damming carries out recycling, the flue gas of removing oil continues to enter next device sack cleaner under the effect of power, the flue gas that enters sack cleaner on composition substantially based on dust, institute's oil-containing remains little, moisture in the flue gas also turns to steam under 180 ℃ high temperature, so sack cleaner can effectively purify dust last in the flue gas; Flue gas through sack cleaner arrives the secondary air-introduced machine through wind pipe, and flue gas is sent final qualified flue gas into chimney and entered atmosphere under the effect of air-introduced machine.Concrete characteristics are as follows:
1, the flue gas of handling through native system reaches or is better than (GB3095-1996) discharge standard, and atmospheric environment is improved.
2, use this device after, can increase service life of cloth bag greatly, reduced the maintenance cost of enterprise, economic effect is obvious.
3, institute of enterprise discharged flue gas reaches discharge standard, atmospheric environment is administered made contribution, and the social benefit of enterprise promotes.
The use of this device and method will be for curbing environmental pollution, solve present government and enterprise and draw the input lot of manpower and material resources of curbing environmental pollution, but fundamentally the technical barrier of contaminated solution problem can not produce secondary pollution simultaneously, produces huge economic and social benefit.
