Abstract
The utility model relates to a waste gas treating device of mixed gas which mainly comprises DOP and also comprises hydrogen chloride, polyvinyl chloride, vinyl chloride and carbon monoxide in the process of producing PVC products. The utility model is composed of a pre-filtering net, a cooling tank, a gas-liquid separating cylinder, a flowing adsorbent bed, etc. The utility model is characterized in that the purifying rate can achieve 95%, the discharge of tail gas is in accordance with the standard without environmental pollution and harm to the human body, and the waste gas can be recycled partially. The utility model has the advantages of convenient arrangement and reasonable process, and is the best choice for purifying the DOP waste gas.
Description
The utility model relates to a kind of DOP emission-control equipment.This based on DOP(phthalic acid Diisooctyl) mist in also contain carbon monoxide, hydrogen chloride, polyvinyl chloride, vinyl chloride, be to produce the mix waste gas that produces in the PVC goods foaming batch-type furnace with stench.In addition, PVC synthetic leather, foaming adhesive plaster, foaming wall paper production process all have these waste gas to produce, and be extremely harmful to environment and human body.
The purpose of this utility model is to provide a kind of device of the DOP of processing mix waste gas, it is made up of prefiltering net 3, cooling tank 6, cool cycles pond 9, gas-liquid separation tube 10, the adsorbent bed 11 that flows etc., it is characterized in that being provided with earlier a prefiltering net 3, one cooling tank 6 is set thereafter, provide cooling water by cool cycles pond 9, one gas-liquid separation tube 10 is set behind cooling tank 6, a mobile adsorbent bed 11 is set subsequently.
Its principle is that industrial waste gas enters prefiltering net 3, but flue gas in the removing exhaust gas and 90% carbon monoxide, through cooling tank 6 EGT is reduced to 50 ℃ by 210 ℃ then, make DOP waste gas become liquid condition, simultaneously also make hydrogen chloride, polyvinyl chloride, vinyl chloride gas become liquid, discharge or recycle by cooling tank 6 outlet at bottoms, do not absorb residual air liquid and enter 10 separation of gas-liquid separation tube, and by mobile adsorbent bed 11 last adsorption cleanings, the gas that makes it to discharge from chimney 12 meets standard-required.
The utility model is easy owing to being provided with, method is reasonable, detects purification efficiency by analysis and can reach 95%, is the efficient apparatus that solves the nature discharging, and a part of gas can be recycled.
The utility model accompanying drawing is a structural representation.Wherein flue 1, air-introduced machine 2, prefiltering net 3, exhaust gas inlet 4, temperature-measuring port 5, cooling tank 6, cooling water pipeline 7, cooling water pump 8, cool cycles pond 9, gas-liquid separation tube 10, adsorbent bed 11, chimney 12 flow.
This device can be done overall or intermediate absorption in the PVC production of articles, prefiltering net 3 is made up of 2 rows, 20 order nickel plating nets, and cooling tank 6 is a calandria, but active carbon or γ one aluminium oxide are adopted in the adsorbent alternating movement of the adsorbent bed 11 that flows.
