The specific embodiment
Below by specific embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.Should be appreciated that enforcement of the present utility model is not limited to the following examples, any pro forma accommodation that the utility model is made and/or change all will fall into the utility model protection domain.
Embodiment:
A kind of high-temperature forming machine treating apparatus for exhaust gas of oil smoke as shown in Figure 1, its main body is absorption tower 11, absorption tower is formed by connecting by top cover and tower body two parts, between top cover and tower body, connects by flange.For ease of maintenance, two manholes 12 are also set on tower body, be each positioned at tower body 1/3rd places.The tower body part on this absorption tower is divided into water spray processing section 3, wet electrostatic falling film absorption section 4 and demist section 5 from bottom to top.At the bottom of absorbing tower, a side arranges exhaust gas inlet 1, and the opposite side at the bottom of tower is provided with oil water separator 9, and the top of water spray processing section arranges water sprinkler system 2, and the water inlet of water sprinkler system 2 arranges tower body outside.The shower nozzle of water sprinkler system 2 distributes in the form of a ring.Water spray processing section is mainly used in removing particle and the cooling that in oil flue waste gas, particle diameter is larger and processes, so that alleviate the pressure of back segment advanced treating.
Wet electrostatic falling film absorption section 4 is made up of the static discharge utmost point 7, moisture film generation device and heat exchanger 10.As shown in Figure 2, moisture film generation device comprises that water pipe, static pole plate 13, static pole plate 13 have multiple circular holes 15 above, and the outward flange of circular hole is fixed with to form the falling film absorption pipe 14 of static wall, forms water film in falling film absorption pipe inner side.Static pole plate and falling film absorption pipe are made up of modified graphite.The axis of falling film absorption pipe 14 and static pole plate 13 are perpendicular.The water inlet 18 of water pipe 16 is arranged in tower body outside wall surface, water pipe 16 forms multiple branch roads in tower body, water pipe is provided with shower nozzle 17 corresponding to the top of each falling film absorption pipe 14, shower nozzle guarantees that liquid flows downward along falling film absorption inside pipe wall, forms one deck liquid film and is attached on tube wall.The static discharge utmost point 7 is positioned at tower body outside, has two, is connected respectively with static pole plate 13.The static discharge utmost point 7 is covered with protective cover 19.Electric field in wet electrostatic falling film absorption section 4 is Wet type electric field, and with respect to dry type electric field, its security performance is higher.After stationary electrode access high pressure, produce electrostatic attraction, the oil content in high-temperature forming machine waste gas is produced to attraction, oil content is separated from waste gas.Moisture film generation device 6 forms water membrane by shower nozzle 17 near the inwall of static pole plate, current from top to bottom, when the oil content in waste gas to static pole plate 13 near time, stopped by water film and be pulled away, guarantee the clean of static pole plate inwall, make the operation that device can be steady in a long-term, reduced maintenance number of times, reduce operating cost.Tubular heat exchanger is mainly the recycling to heat, and high-temperature forming machine waste gas from bottom to top, is travelled by water in heat exchanger tube pass, by carrying out heat exchange with high-temperature forming machine waste gas contact-making surface, the heat in waste gas is converted into the heat in water.
Demist section is positioned at the top of absorption tower tower body part, is provided with demister 8 in demist section.
Various particles in waste gas are collected phenomenon because of charged generation, are towed on static pole plate, and moisture film generation device has formed water membrane on static pole plate top layer in addition, the particle erosion settling down can be walked.Spray pretreated waste-gas heat through water still higher, heat exchanger can reclaim a part of heat energy, saves the energy.
The high-temperature forming machine oil flue waste gas treatment process that said apparatus adopts is as follows:
1) first high-temperature forming machine oil flue waste gas carries out pretreatment through the water spray processing section of end under tower, circulation fluid is from the shower nozzle ejection of annular distribution, the water smoke producing fully contacts with oil-contg. smoke, and collision mutually, the larger-diameter smoke particle of major part containing for removing oil flue waste gas;
2) the wet electrostatic falling film absorption section that high-temperature forming machine oil flue waste gas enters tower top upper end after the pretreatment of water spray processing section is again carried out static falling liquid film advanced treating, waste gas is from bottom to top when flowing through in falling film absorption pipe, cooled by the heat exchanger between falling film absorption pipe, aqueous vapor in waste gas and oil gas respectively condensation become water smoke and mist of oil, at this moment under high-voltage pulse electrostatic field, mist of oil and water fog particle are together by highdensity electron attachment, charged, make directional migration to inside pipe wall, there is one deck liquid film at falling film absorption inner tube layer in addition, mist of oil and water fog particle that migration is come are washed away and take away by liquid film, thereby play the effect of purifying exhaust air,
3) tail gas after advanced treating is by the aiutage qualified discharge of tower top, and the waste water producing in purification process passes into oil water separator and processes, and waste water after treatment is got to absorption tower by circulating pump and recycled, and waste oil can fully be reclaimed.Enter in circulation water layer through the oil content of removing, therefore circulation fluid is carried out to water-oil separating processing, upper strata oil-water-layer is collected to take-away, lower floor's clear water layer is returned secondary utilization in waste gas absorption tower by water pump again, can further economize on resources like this, reduce operating cost.
Above-described embodiment is preferably scheme of one of the present utility model, not the utility model is done to any pro forma restriction, also has other variant and remodeling under the prerequisite that does not exceed the technical scheme that claim records.
