Description
Technical field
The utility model relates to a kind of Process Technology of Polymer tail gas clean-up treatment system.
Background technology
The peculiar smell that rubber production and processing factory, plastic molding and processing plant, chemical plant etc. are brought and tail gas pollution problem, caused people and more and more paid close attention to.Peculiar smell or other pollutants enter human body by contact, breathing and the approach such as water and food, be distributed in blood and each organ, cause the disease of respiratory system, the circulatory system, digestive system, internal system and nervous system etc., and the stimulation of long-term peculiar smell, feeling fatigue of people can be caused, increase the psychological pressure of people.Therefore the purified treatment of the tail gas of Process Technology of Polymer factory generation just seems abnormal important.
For tail gas clean-up process, people possess some special knowledge for a long time, and are widely used at industrial circle, but owing to containing the harmful components such as a large amount of hydrogen sulfide in the tail gas of the generation such as rubber mill or plastic molding and processing plant, research shows, when concentration of hydrogen sulfide reaches 700 × 10
-6time above, can cause people clouded in mind in the short time, breathe and to stop and dead, and the general process ubiquity equipment heaviness to such tail gas, system complex, inefficiency, the problem such as with high costs.
Utility model content
The utility model proposes a kind of Process Technology of Polymer tail gas clean-up treatment system, this system is used for the tail gas clean-up process that the factory such as rubber mill, plastic molding and processing plant, chemical plant produces, and has that system flow is simple, gas purification efficiency is high, the lower-cost advantage of gas purification.
The technical solution of the utility model is: a kind of Process Technology of Polymer tail gas clean-up treatment system, this system is made up of cyclone separator, sack cleaner, caustic wash tower, low temperature plasma tail gas treatment device.Described cyclone separator gas vent is connected with sack cleaner gas access, sack cleaner gas vent is connected with caustic wash tower gas access, caustic wash tower gas vent is connected with low temperature plasma tail gas treatment device gas access, low temperature plasma tail gas treatment device gas vent evacuate air.
Described cyclone separator gas vent is connected with sack cleaner gas access, and plant tail gas enters after the large granular impurity carried secretly isolated by cyclone separator and enters sack cleaner, prevents large particulate matter from entering low-temperature plasma device and blasts.
Described sack cleaner entrance is connected with cyclone separator gas vent, and sack cleaner gas vent is connected with caustic wash tower gas access.The gas removing large particulate matter through cyclone dust collectors removes the particle of small particle diameter in sack cleaner, ensures that gas enters the security of follow-up equipment further.
Described caustic wash tower gas access is connected with sack cleaner gas vent, and caustic wash tower purified gas outlet is connected with low temperature plasma tail gas treatment device.Gas after the removing of the first two solid particle enters caustic wash tower, utilizes alkaline absorption solution to remove hydrogen sulfide a large amount of in gas and other mineral acid gas.
Described low temperature plasma tail gas treatment device gas access is connected with caustic wash tower purified gas outlet, and the gas of low temperature plasma tail gas treatment device gas vent is directly emptying.Tail gas through removing a large amount of hydrogen sulfide and other mineral acid gases enters low temperature plasma tail gas treatment device, carry out the process of low concentration degraded volatile organic contaminant (VOCs), clean-up effect reaches more than 90%, and gas after treatment can be directly emptying.
The utility model beneficial effect is compared with prior art:
1, described cyclone separator gas vent is connected with sack cleaner gas access, sack cleaner gas vent is connected with caustic wash tower gas access, Process Technology of Polymer gas tail gas is after cyclone separator and sack cleaner, particulate matter in gas is removed, ensure that gas enters the security of low temperature plasma tail gas treatment device.
2, described caustic wash tower gas vent is connected with low temperature plasma tail gas treatment device gas access, can remove the mineral acid gas in tail gas, a small amount of VOCs contained can be removed again, ensure that the innocuousness of cleaning of off-gas in tail gas.
Accompanying drawing explanation
Accompanying drawing is that a kind of Process Technology of Polymer tail gas clean-up of the utility model treatment system is formed and flow chart, and 1 is cyclone separator, and 2 is sack cleaner, and 3 is caustic wash tower, and 4 is low temperature plasma tail gas treatment device.
Detailed description of the invention
Below in conjunction with accompanying drawing, concrete enforcement of the present utility model is described in further detail.
As shown in Figure 1, described a kind of Process Technology of Polymer tail gas clean-up treatment system is made up of cyclone separator (1), sack cleaner (2), caustic wash tower (3), low temperature plasma tail gas treatment device (4).
Described cyclone separator (1) gas vent is connected with sack cleaner (2) gas access, the plant tail gas such as rubber mill, plastic molding and processing plant, chemical plant enter after the large granular impurity carried secretly isolated by cyclone separator (1) and enter sack cleaner (2), prevent large particulate matter from entering low temperature plasma tail gas treatment device (4) and cause danger.
Described sack cleaner (2) entrance is connected with cyclone separator (1) gas vent, and sack cleaner (2) gas vent is connected with caustic wash tower (3) gas access.The gas removing large particulate matter through cyclone dust collectors (1) enters sack cleaner (2), through the filtration of filter bag, finely ground particle substance is blocked in outside filter bag, the granular gas removing small particle diameter enters caustic wash tower (3) through filter bag, ensures that gas enters the security of follow-up equipment further.
Described caustic wash tower (3) gas access is connected with sack cleaner (2) gas vent, and caustic wash tower (3) purified gas outlet is connected with low temperature plasma tail gas treatment device (4).Gas after the removing of the first two solid particle enters caustic wash tower (3), alkaline absorption solution sprays from top to bottom, contact with gas and carry out absorption neutralization reaction, remove hydrogen sulfide a large amount of in gas and other mineral acid gas, enter through purified gas the purified treatment that low temperature plasma tail gas treatment device (4) carries out next step.
Described low temperature plasma tail gas treatment device (4) gas access is connected with caustic wash tower (3) purified gas outlet, and the gas of low temperature plasma tail gas treatment device (4) gas vent is directly emptying.Process removes a large amount of hydrogen sulfide and other mineral acid gas cleaning gas enters low temperature plasma tail gas treatment device (4), carries out the process of low concentration degraded volatile organic contaminant (VOCs).Under the electric field action of low temperature plasma tail gas treatment device (4), what medium discharge produced takes in a large number and can bombard organic pollutant molecule by electronics, make it ionize, dissociate and excite, then physics, the chemical reaction of series of complex has just been caused, complicated macromolecule contaminant is made to change simple Small molecular safe material into, or make poisonous and harmful substance be transformed into material that is nontoxic or the low evil of low toxicity, thus pollutant is degraded, its clean-up effect reaches more than 90%, and gas after treatment can be directly emptying.
Finally it should be noted that; more than describe and be only preferred embodiments of the present utility model instead of the restriction to the utility model technology; any equivalent replacement that the utility model craft technical feature is done or improve accordingly, still within protection domain of the present utility model.
