Abstract
The utility model provides a kind of nitric acid device for recycling exhaust gas, comprise booster pump, surge tank, absorption tower, make-up tank, it is characterized in that, described booster pump is connected with surge tank, described surge tank is connected with absorption tower, and described absorption tower is connected with make-up tank.This device carries out liquefaction absorption by being delivered to tourie through surge tank after nitric acid exhaust gas, then the absorbing liquid of gained is delivered to the concentration of make-up tank adjustment gained nitric acid liquid.This device every 24 hours recyclable 25 ~ 30% nitric acid 800kg, recovery process is simple, reduces production cost, and has significant environment protecting.
Description
Technical field
The utility model relates to chemical industry environmental protection apparatus field, is specifically related to device for recycling exhaust gas during a kind of nitric acid production.
Background technology
Along with the development of China's industrial or agricultural, the especially development of chemical industry, environmental problem becomes increasingly conspicuous.In nitric acid production preparation process, have the generation of nitric acid vapor, be absorb with air-introduced machine sucking-off production facility inner exhaust gas in prior art, then enter sewage disposal system and process.In absorption processing procedure, NO
2produce amount of heat when water absorbs, cause absorbing liquid temperature to raise, resistance limit NO
2further absorption, add ammonia in waste water, nitrogen treating capacity, cause absorb poor processing effect, easily to environment.
Utility model content
One or more during the utility model is intended to overcome the above problems.
For solving the problem, the utility model provides a kind of nitric acid device for recycling exhaust gas, comprises booster pump, surge tank, absorption tower, make-up tank, it is characterized in that, described booster pump is connected with surge tank, and described surge tank is connected with absorption tower, and described absorption tower is connected with make-up tank.
Wherein, described absorption tower has installed condenser coil additional, the temperature on absorption tower is controlled below 40 DEG C.
Preferably, described condenser coil is polypropylene graphite coil pipe.
The beneficial effects of the utility model: this device carries out liquefaction absorption by being delivered to tourie through surge tank after nitric acid exhaust gas, assimilation effect is good, the absorbing liquid of gained up to 40%, then can be delivered to the concentration of make-up tank adjustment gained nitric acid liquid by absorption strength.This device every 24 hours recyclable 25 ~ 30% nitric acid 800kg, recovery process is simple, reduces production cost, and has significant environment protecting.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1. booster pump, 2. surge tank, 3. absorption tower, 4. configured slot.
Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1, the utility model comprises booster pump 1, surge tank 2, absorption tower 3, make-up tank 4, it is characterized in that, described booster pump 1 is connected with surge tank 2, and described surge tank 2 is connected with absorption tower 3, and described absorption tower 3 is connected with make-up tank 4.
Wherein, described absorption tower 3 has installed condenser coil additional, the temperature on absorption tower 3 is controlled below 40 DEG C.
Preferably, described condenser coil is polypropylene graphite coil pipe.
The beneficial effects of the utility model: this device carries out liquefaction absorption by being delivered to tourie through surge tank after nitric acid exhaust gas, assimilation effect is good, the absorbing liquid of gained up to 40%, then can be delivered to the concentration of make-up tank adjustment gained nitric acid liquid by absorption strength.This device every 24 hours recyclable 25 ~ 30% nitric acid 800kg, recovery process is simple, reduces production cost, and has significant environment protecting.
Above embodiment is only the utility model a kind of embodiment wherein, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
