Abstract
The invention relates to a method for processing organic matter waste gas generated in the coating process. According to the method, organic matter and cooling liquid recycling is achieved through collection of organic matter waste gas, filtering and dedusting, condensation, separation and cooling and backflow. The method is simple in operation, easy to implement, safe and reliable, the contact area of the cooling liquid and the organic matter waste gas is increased through a top spraying mode, the cooling effect is good, the liquefied organic mater is mixed with the cooling liquid, and the organic matter in the organic matter waste gas is fully absorbed; the waste gas is further absorbed through an absorber to make emission of the waste gas meet the standard, pollution to the environment is avoided, recycling of the organic matter and the cooling liquid is achieved as well, and the economical benefits are increased greatly.
Description
Technical field
The present invention relates to a kind of processing method of waste gas, specifically a kind of processing method of the organic compounds to producing in coating procedure.
Background technology
, not only containing comprising as gas chromatographies such as toluene, dichloropropane, dichloroethanes, methyl alcohol, ortho-chlorotolu'enes, also there is steam and a small amount of solid or liquid particles in the organic compounds produced in coating production process.Due in the whole production process of coating production line, produce and generally continue to carry out in the condition of high temperature, so the organic compounds high temperature discharged is approximately 60-90 DEG C, the discharge capacity of organic compounds is very large, and the content of organics in this large amount of organic compounds is also very important.Clearly, the content of organics among this organic compounds does not reach environmental emission standard.Therefore, from cost standpoint, preferred recycling.
At present, the method processing these organic compounds mainly contains two kinds, one is high-temperature heating decomposition method, namely organic compounds is flow through high-temperature heating equipment, make organic substance decomposing burn into carbon dioxide and water, the shortcoming of the method is: investment is large, complicated operation, dangerous in production, the accidents such as equipment fault fire hazardous, blast, decomposing the carbon dioxide greenhouse gas that discharges and undecomposed organic solvent can contaminated air again; Another kind method is that the shortcoming of this method is: being in great demand of active carbon with the organic matter in charcoal absorption air, and equipment is complicated, and investment amount is large, incomplete to the absorption of pernicious gas, and the process of the active carbon lost efficacy comparatively bothers.
Therefore, need a kind of can organic matter in recycling organic compounds, organic compounds can be made again to discharge the technique reaching environmental standard.
Summary of the invention
The object of the present invention is to provide a kind of processing method of the organic compounds to producing in coating procedure, can organic matter in recycling organic compounds, the discharge of organic compounds can be made again to reach environmental standard.
For achieving the above object, the invention provides following technical scheme:
To a processing method for the organic compounds produced in coating procedure, step is as follows:
1) organic compounds is collected: introduce in gas collector by organic compounds by blower fan and wireway;
2) dust removal by filtration: the organic compounds in gas collector is incorporated in filter through wireway and carries out except solid particle and liquid particles;
3) condensation: the organic compounds through metre filter dedusting is incorporated in condenser by wireway, the cooling fluid of the purification utensil through condenser overhead is gone out from the top spray of condenser, organic matter in organic compounds is converted into liquid state by gaseous state after cooling, and mix with cooling fluid, flow in separator by the drainage tube bottom condenser, after fixed gas in organic compounds then flows into absorber by the wireway of condenser overhead, then enter in air;
4) be separated: the mixing material in separator is through stratification, upper strata is organic matter, lower floor is cooling fluid, and organic matter flows in organic matter reservoir by the organic outlet of separator middle and upper part, and cooling fluid flows in coolant reservoir by the cooling liquid outlet of separator bottom;
5) cooling for reflux: the cooling fluid in coolant reservoir, after cooling down, flows to step 2 by blowback) condenser overhead clarifier in, realize recycling of cooling fluid.
As the further scheme of the present invention: the organic compounds in described step 1) comprises toluene, dichloropropane, dichloroethanes, methyl alcohol, ortho-chlorotolu'ene, steam, solid particle and liquid particles.
As the further scheme of the present invention: in described step 3), clarifier is fine sand and active carbon purifying device, and cooling fluid is cold water or cool brine, and absorber is active carbon adsorber.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention increases the contact area of cooling fluid and organic compounds by top spray mode, good cooling results, and the organic matter of post liquefaction is mixed with cooling fluid, absorbs the organic matter in organic compounds fully.
Operation is simple in the present invention, safe and reliable, and the organic gas in organic compounds absorbs process completely, and toxic emission is up to standard, not only avoid the pollution of environment, also achieves the recycling of organic matter and cooling fluid, substantially increases economic benefit.
