Abstract

The utility model discloses a device for purifying and treating rubber soot mixed peculiar smell waste gas, which can separate, decompose and purify rubber soot mixed peculiar smell waste gas in sequence. Separation is achieved in the way that rubber smoke oil and dust are separated and collected through physical spraying; decomposition is achieved in the way that sulfide mainly containing sulfur dioxide is decomposed and reacted through NaOH solution to generate sodium sulfate soluble in water; and the purification is achieved by an adsorption device adopting active carbon absorption cotton, so that dust and rubber oil, as well as sulfide and volatile organic compound (VOC),can be effectively eliminated to realize purification treatment. The purifying rate of hydrogen sulfide, hydroxide, non-methane hydrocarbon (NMHC) and the like reaches more than 99 percent and meets the national emission standard (GB16297-1996). Therefore, the mental and physical health of workers and atmospheric environment around the factory are effectively protected.

Background technology

Rubber industry is one of essential industry that is related to national economy, defence and military and people's lives, along with rapid development of automobile industry, and the tire of China, the also fast development of rubber industry.In rubber-based products is produced, used a large amount of organic solvents, auxiliary agent etc., contained many toxic chemical substances, can be discharged in the environment, health and environment have been caused the influence of instant or potential accumulation by modes such as water, gas, solid waste.

Especially at refining glue, calendering, extrude, the heat plasticization of operations such as sulfuration, during oxidation, rubber may dissociate monomer and harmful analyte, other part low-boiling-point organic compound matter also discharge and produce series of chemical in a large number in the raw material simultaneously, can form intensive rubber smoke mixing peculiar smell waste gas, has the special intolerable stench that makes us, can cause respiratory system, the disease of nerve center system and hematological system, particularly volatile benzene, toluene and formaldehyde can cause very big injury to health, not only the grievous injury workman's is healthy, and causes severe contamination for the atmospheric environment around the plant area.

Rubber smokes etc. mix peculiar smell waste gas and mainly are made up of steam, dust, sulfide and VOC (VOC), and wherein sulfide and VOC (VOC) are the important substance that produces stench.In the present rubber enterprise of China, nearly all be that the method by force ventilation or natural ventilation directly is discharged in the atmosphere, alleviating the job shop exhaust emission, and waste gas is not purified.Perfect along with Environmental Protection in China rules, technical policy, the waste gas in the rubber production process will effectively be purified and be administered.

The utility model content

The purpose of this utility model provides a kind of rubber smoke mixing peculiar smell exhaust gas purification and treatment device; can carry out corresponding purified treatment to the rubber smoke mixing peculiar smell waste gas that produces in the rubber production process; wide model uses at elastomeric compound production line, reclaimed rubber desulfurize line, tyre vulcanization zone, rubber production line; to promoting green production, protection environment, emission abatement and protection operator physical and mental health have positive social benefit and good economic benefit.

The purpose of this utility model is to be achieved through the following technical solutions:

A kind of rubber smoke mixing peculiar smell exhaust gas purification and treatment device, comprise air-introduced machine and air intake pipeline, it is characterized in that: described air intake pipeline is equipped with the spray pipeline and links to each other with fluid box by the circulatory system successively by separator box, decomposition case and purifying box in the described separator box; Described decomposition case is equipped with the spray pipeline and links to each other with the fluid box that the mixed solution that contains NaOH is housed by the circulatory system; Adsorbent equipments such as active carbon absorbent tampons are installed in the described purifying box.

Described purifying box is connected with the steam pipe line that is used for cleaning active charcoal absorbent tampons.

Rubber smoke mixing peculiar smell exhaust gas purification and treatment device described in the utility model, by rubber smoke mixing peculiar smell waste gas being adopted the mode of fractional sedimentation, reaction, absorption, can effectively eliminate its dust that contains, glue oil, sulfide and VOC (VOC).Sulfur dioxide, hydrogen sulfide, hydroxide, purifying rates such as NMHC reach more than 99%, reach discharging standards (GB16297-1996).

The specific embodiment

Fig. 1 provided that rubber smoke mixing peculiar smell exhaust gas purification and treatment device described in the utility model adopted process chart, in device, the glue smoke waste gas of on-site collection is handled through three process successively:

Separate: rubber smoke mixing peculiar smell waste gas is fed in the separator box, reverse spray contains the solution water of NaOH, adopts the self-loopa spray, and the glue tobacco tar is bubbled through the water column, flow into the waste oil accumulator tank with liquid water and reclaim, dust is recycled to disposal box by gravitational settling screw clamp bottom.

Decompose: feed and decompose in the case by separating the remaining pernicious gas in back, continuing mixed solution that spray contains NaOH is that main sulfide decomposes, reacts and make it to generate water-soluble sodium sulfite to sulfur dioxide.The recirculated water of the desulfurization that contains sodium sulphate and placement calcium oxide are generated calcium sulfite.Insoluble calcium sulfite is removed water repeated use capable of circulation by sedimentation separation from recirculated water.

Purify: feed purifying box by remaining pernicious gas after separating, decomposing, by active carbon absorbent tampons adsorbent equipment, the VOC that contains in the adsorbed gas (VOC) can make active cotton maintenance unimpeded by steam clean.

Fig. 2 has provided the structure chart of a concrete device using said method, as shown in Figure 2, draw from tablet press machine, the air intake pipeline 2 of the cold machine climbing of glue section is successively by separator box 3, decompose case 4, with purifying box 5, tail end at purifying box 5 is equipped with air-introduced machine 1, the on-the-spot rubber smoke mixing peculiar smell waste gas that produces is under the effect of air-introduced machine 1 draft, at first enter separator box 3, the circulatory system that the spray pipeline forms by circulating pump 6 is installed in separator box 3 to link to each other with fluid box 7, flue gas is under the reverse spray effect of the solution water that contains NaOH, the glue tobacco tar is bubbled through the water column, flow into the waste oil accumulator tank with liquid water and reclaim, dust is recycled to disposal box by gravitational settling screw clamp bottom.

Decompose case be equipped with the spray pipeline by the circulatory system with the fluid box 7 that contains NaOH solution be housed link to each other, to sulfur dioxide is that main sulfide carries out chemical reaction, making it to decompose, mainly is that sulfur dioxide and NaOH collide and reacts, and it is water-soluble to be reacted into sodium sulphate.The recirculated water of the desulfurization that contains sodium sulphate and placement calcium oxide are generated calcium sulfite.By sedimentation separation insoluble calcium sulfite is removed from recirculated water, water repeated use capable of circulation if the pH value of solution is lower than 5 and adds NaOH and make it the concentration that keeps certain in the fluid box 7, is guaranteed the effect of chemical reaction.

Active carbon absorbent tampons adsorbent equipment is installed in the purifying box 5, the VOC that contains in the adsorbable gas (VOC), purifying box 5 is connected with steam pipe line, can make active cotton maintenance unimpeded by steam clean, when discharging has peculiar smell, need to change active cotton or timely steam clean.
