Abstract
The utility model discloses an efficient chemical waste gas treatment system which comprises a cyclone dust collector, a water purification tower, a bag-type dust collector, a plasma purifier, a high activation purification tower and a chimney, wherein the cyclone dust collector is arranged at the initial end of the efficient chemical waste gas treatment system; the water purification tower is connected with the cyclone dust collector; the gas inlet of the bag-type dust collector is connected with the water purification tower, and the gas outlet of the bag-type dust collector is connected with the plasma purifier; the high activation purification tower is arranged behind the plasma purifier; the chimney is connected with the gas outlet of the high activation purification tower. The efficient chemical waste gas treatment system has an excellent removal effect on waste gas such as phthalic anhydride, ammonia gas and smoke dust, so that the quality of the waste gas treated via the efficient chemical waste gas treatment system is ensured after exhausted in the air.
Description
Technical field
The utility model relates to a kind of exhaust treatment system, relates in particular to the cleaning treatment system of the chemical plant waste gas of producing lubricant, dye well plasticizer etc.
Background technology
Produce the chemical plant such as lubricant, dyestuff, plasticizer and can produce the waste gas such as a large amount of phthalic anhydrides, ammonia, flue dust.Phthalic anhydride is phthalic anhydride, can have spread effect to people's eye nose larynx, can cause asthma and chronic bronchitis, belongs to lower toxicity gas; And ammonia is the toxic gas with penetrating odor; Flue dust has polluted atmospheric environment.Because phthalic anhydride is met high heat, naked light or contacts with oxidant, there is the danger that causes burning, make its purification process safety requirements higher, the existing processing method for this waste gas has: 1. the direct burning method of high temperature, although the method can be removed phthalic anhydride effectively, but can cause the secondary pollutions such as bioxin, simultaneously low to the removal efficiency of ammonia; 2. chemiadsorption: water or acid solution etc. carries out gas liquid reaction and removes waste gas, and the method can be effective to ammonia and part dust, and phthalic anhydride is dissolved in organic solvent more; 3. spray process and charcoal absorption combined techniques, but the limited and saturated rear difficult processing of the adsorbance of active carbon.Therefore, for this waste gas, be badly in need of a kind of efficient waste gas processing method.
Utility model content
In order to solve the deficiencies in the prior art, the utility model provides a kind of efficient chemical industry exhaust treatment system.
The technical solution of the utility model is: a kind of efficient chemical industry exhaust treatment system, comprising: cyclone dust collectors, water purifying column, sack cleaner, plasma purifier, overactivity purifying column, chimney; Its technical essential is: the initial end of native system is cyclone dust collectors, coupled is water purifying column, the air inlet of sack cleaner is connected with water purifying column, its outlet side is plasma purifier, overactivity purifying column is arranged on after plasma purifier, and chimney is connected with the gas outlet of overactivity purifying column.
A kind of efficient chemical industry exhaust treatment system of the utility model, its process route is: a, cyclone dust collectors carry out preliminary Separation of Solid and Liquid dedusting; Moisture film in b, water purifying column dissolves ammonia and part dust; C, sack cleaner, can fully remove the particle that particle diameter is greater than 0.3 micron; D, plasma apply voltage to soot dust granule, when applied voltage reaches the working voltage of gas, gas molecule is breakdown, produces the mixture that comprises electronics, various ion, atom and free radical, hydrocarbon is converted into carbon dioxide and water, and phthalic anhydride molecule is removed herein substantially; Plant adsorption liquid in e, overactivity purifying column promptly with emission molecule effect, emission molecule is finally removed, last clean clean gas enters atmosphere from chimney.
The beneficial effects of the utility model are: cyclone dust collectors are greater than the particle of 5 microns for particle diameter good removal effect, and the particle that is 3 microns to particle diameter also has 80%～85% clearance; Water purifying column has good catharsis to ammonia, and water cooked adsorbent safety non-pollution, cost-saving; Sack cleaner has further been processed dust granules, and the dust size that makes to enter plasma purifier is less, can not cause burden to equipment; Plasma purifier and overactivity purifying column can reach more than 95% efficiency of dust collection, have guaranteed to discharge the quality of air.
Accompanying drawing explanation
The utility model has accompanying drawing 1 width.
Fig. 1 is a kind of efficient chemical industry exhaust treatment system schematic diagram.
Sequence number explanation in figure: 1, cyclone dust collectors, 2, water purifying column, 3, sack cleaner, 4, plasma purifier, 5, overactivity purifying column, 6, chimney.
The specific embodiment
The utility model provides a kind of efficient chemical industry exhaust treatment system, comprising: cyclone dust collectors 1, water purifying column 2, sack cleaner 3, plasma purifier 4, overactivity purifying column 5, chimney 6; The initial end of native system is cyclone dust collectors 1, coupled is water purifying column 2, the air inlet of sack cleaner 3 is connected with water purifying column 2, its outlet side is plasma purifier 4, overactivity purifying column 5 is arranged on after plasma purifier 4, and chimney 6 is connected with the gas outlet of overactivity purifying column 5.
When this uses novel efficient chemical industry exhaust treatment system operation, in a step, waste gas enters cyclone dust collectors 1, and 1 pair of waste gas of cyclone dust collectors carries out preliminary purification, solid-liquid initial gross separation in this equipment, and remove part dust granules.
In b step, the waste gas after cyclone dust collectors 1 enters in water purifying column 2, and ammonia and part dust are dissolved by the moisture film in water purifying column 2, and ammonia is removed substantially.
In c step, remainder of exhaust gas enters sack cleaner 3, and sack cleaner 3 has been removed the most of particle in waste gas, and the burden that has alleviated subsequent processing device has also improved whole purification efficiency simultaneously.
In d step, after sack cleaner 3 is processed, waste gas enters in plasma purifier 4, and plasma purifier 4 decomposes emission molecule within the extremely short time, original molecular scission, hydrocarbon is converted into carbon dioxide and water, and phthalic anhydride molecule is removed in a large number;
In e step, in order to guarantee the removal efficiency of the emission molecules such as phthalic anhydride, the waste gas of processing through plasma purifier 4 finally enters in overactivity purifying column 5, vegetation water has wherein been removed the phthalic anhydride in remainder of exhaust gas, peculiar smell, dust etc. after reacting with emission molecule, final clean gas enters atmospheric environment through chimney 6.
