A device for treating industrial waste gas. The utility model belongs to a purification device for separating waste gas. The purpose is to provide a device for treating industrial waste gas. It uses air as the medium, uses liquid air or liquid nitrogen to solidify the poisonous gas ( _SO2, etc.) cooled by water through the absorption pool, and then heats the solidified poisonous gas with cooling water to recover the industrial waste gas treatment device. The characteristic is that it includes a treatment part and a recovery part; the treatment part adopts 1 or 2 or 3 or more absorption pools and liquid nitrogen bottles connected in series through a gas pipeline to form a single-group device; the above-mentioned treatment part and recovery part are a single group device or multiple devices connected in parallel. The utility model has the advantages of simple equipment and small footprint; convenient operation and easy mastery of technology; easy-to-obtain and easy-to-regenerate raw materials; good treatment effect and no secondary pollution; . It is suitable for the treatment of harmful and toxic gases in fully enclosed work areas such as large chemical plants, nuclear industries and nuclear submarines.

Description

A kind of improvement industrial waste gas device

Technical field

The utility model belongs to the purifier that separates waste gas.

Background technology

Industrial mainly is that the employing wet method is a chemical absorption method in the background technology aspect administering waste gas, need utilize the acid-base neutralization reaction to eliminate SO ₂Deng gas, so there is following problem in this Faxian: 1. the soda acid consumption is very considerable; 2. the secondary pollution of low value discarded object; 3. take up an area of in a large number; 4. a large amount of contaminated wastewaters.Although the employing active carbon adsorption that grow up the seventies in 20th century carries out exhaust-gas treatment, yet the fatal shortcoming of this method is that the charcoal absorption amount is little.Though exploitation has in recent years adopted modification absorption and band to press adsorption technology to improve the charcoal absorption amount, all has adsorption equilibrium and chemical equilibrium problem, can't reach the high standard of toxic gas zero-emission, the modification adsorption technology also need utilize HNO in addition ₃, NH ₃, soda acid such as HCN, also produce the low value discarded object secondary pollution problem of (as dilute sulfuric acid very) simultaneously.All ways all exist treatment step many, the problem that can't realize in a step.

Summary of the invention

The purpose of this utility model is to provide a kind of improvement industrial waste gas device, and it is to be media with the air, utilizes liquid air to make toxic gas (SO after water cooling by absorption cell ₂Deng) solidify, again the toxic gas that solidifies is made the improvement industrial waste gas device of its recovery with the cooling water heating.The utility model is realized with following mode: a kind of improvement industrial waste gas device, and it is characterized in that it comprises improvement part and recovery section: this improvement part head end is an air inlet pipe 9, this air inlet pipe 9 is communicated with to be inserted in absorption cells 2; Dress liquid air or liquid nitrogen in the liquid nitrogen bottle 1, there is crane 3 its bottle bottom, and bottleneck has defrosting cover plate 13; Absorption cell 2 places liquid air or liquid nitrogen in the liquid nitrogen bottle 1, inserts air inlet pipe 9 at the pond of absorption cell 2 oral area; Absorption cell 2 necks have seal cover cover 5 and connect the logical mouth of pipe 10 of bleeding, and neck also is equipped with fixed mount 4, on the seal cover cover 5 fixed mount 4 are housed also; Fibre optic image transmission sensor 6 also is housed on absorption cell 2; It is to be composed in series by the absorption cell more than 1 or 2 or 3 or 32, and logical with appendix 7 connections between the absorption cell 2 of per 2 serial connections, and valve 8 all is housed; End is the mouth of pipe 10 of bleeding; This recovery section has cooling pond 11 and waste gas reclaims lid pipe 12, and heat-exchange tube 14 is arranged at 11 bottoms, cooling pond, and these heat-exchange tube 14 terminal air inlet pipe 9 with the improvement part are connected; Above-mentioned improvement part and recovery section are single group device or many groups device in parallel.The simple occupation of land of the equipment that the utlity model has is little; Easy to operate technology is easily grasped; Raw material is easy to get and easily regenerates; Good and the non-secondary pollution of treatment effect; The advantage that valuable toxic gas easily reclaims.Particularly it and background technology relatively, having not need be with any acid, alkali, salt even organic matter; Basic non-secondary pollution; Take up an area of little; Do not need high-tension apparatus during processing; Substantially satisfy the substantive distinguishing features and the progress such as high standard of toxic gas zero-emission.The utility model widely is used for effective improvement of chemical industry and military enterprise's poisonous and harmful tail gas.Be applicable to the improvement of totally-enclosed workspace toxic gas such as large chemical plant, nuclear industry toxic and harmful compact district and nuclear submarine.1. it has realizes the industrial production greenization; 2. realize that exhaust-gas treatment and reclaimer are integrated; 3. one step of exhaust-gas treatment finishes; 4. comfortable working environment, intensity of workers is little, and the amount of labour greatly reduces; 5. small investment, instant effect, cost is low, and is effective; 6. take up an area of little; 7. the abundant raw material and the easily good effect of regeneration that is easy to get.

The specific embodiment

Now the utility model is described in further detail in conjunction with the accompanying drawings.

With reference to Fig. 1-Fig. 4, the utility model adopts 2 one groups of tandem arrangements of absorption cell shown in Figure 1 when administering industrial waste gas, also can adopt absorption cell shown in Figure 6 more than 2 group shunting means.As containing a large amount of SO in the waste gas ₂Deng toxic and harmful, enter from air inlet pipe 9, with the air media, utilize liquid air to make SO by absorption cell 2 ₂Solidify Deng toxic gas.The back gas that purifies air connects air exhauster from the mouth of pipe 10 of bleeding and discharges emptying.With reference to Fig. 5, again the toxic gas that solidifies is entered recovery section, process is to start crane 3 liquid nitrogen bottle 1 is reduced, and absorption cell 2 is taken off and insert waste gas at its pond oral area and reclaim lid pipe 12, makes its recovery with the cooling water heating.The fibre optic image transmission sensor is housed on the absorption cell 2 shows that green, red led indicates its waste gas solid state locations and close tracheae turnover valve automatically.The utility model principle is the dependence according to fusing point and temperature, reaches the high standard of toxic emission by the temperature of the hierarchy of control.Adopt this device to CO ₂, NH ₃, SO ₂Measuring Deng thing, is 1.33 * 10 in the vacuum of vacuum system ^-3～1.33 * 10 ^-4Do not detect measured object under the Pa.
