Abstract
The utility model provides a sour water strip ammonia purification liquid ammonia decoloration device, includes device main part, its characterized in that: the device main part includes ammonia condenser, liquid ammonia decoloration jar, liquid ammonia holding vessel, and according to the order of ammonia condenser, liquid ammonia decoloration jar, liquid ammonia holding vessel in proper order by duct connections, be equipped with active carbon edulcoration structure in the liquid ammonia decoloration jar, ammonia behind the ammonia compressor becomes liquid ammonia through the ammonia condenser postcooling, the oil in sloughing liquid ammonia after the active carbon edulcoration structure of liquid ammonia in liquid ammonia decoloration jar, the impurity of phenol, and late arrival liquid ammonia storage tank is deposited. The flow is simple, convenient operation, small investment. And when raw materials sewage receives the impact, when raw materials sewage petroleum company of the people's republic of china content, phenol content exceeds standard and when bringing the ammonia purification system into, can ensure that the quality of liquid ammonia is not influenced, still reaches the national standard requirement.
Description
Technical field
This utility model relates to a kind of decoloration device, is specifically related to a kind of sewage stripping ammonia refining liquefied ammonia decoloration device.
Background technology
In petrochemical production process, some sewage can be supervened, these sewage all contain the higher hydrogen sulfide of concentration and ammonia, just polluting the environment if do not removed, the normal ecosystem of welding.These sour waters are commonly referred to collectively as acid water.Acidic water stripping device is the acid water that each process unit of special disposal oil plant is discharged, to remove the polluted medias such as H2S, NH3 of containing in acid water.Single column side line stripping process utilizes hydrogen sulfide obstructed with the volatility of ammonia, high concentration hydrogen sulfide gas is obtained at the top of tower, and the ammonia of high concentration is extracted out at the middle part of tower, and the impurity such as oil in sewage, phenol can be brought to Ammonia purification system with the thick ammonia of side line, and Ammonia purification system cannot effectively remove the material of oil, phenol, from but liquefied ammonia after ammonia refining takes on a red color, residue is cyan oil film, liquefied ammonia purity does not reach Standard.
Utility model content
The purpose of this utility model is in that for the defect above having technology, it is provided that a kind of flow process is simple, the liquefied ammonia decoloration device that cost of investment is low.
For the deficiency overcoming prior art to exist, the technical scheme that this utility model provides is: a kind of sewage stripping ammonia refining liquefied ammonia decoloration device, including apparatus main body, it is characterized in that: described apparatus main body includes ammonia condenser, liquefied ammonia bleacher, liquefied ammonia holding vessel, and according to ammonia condenser, liquefied ammonia bleacher, the order of liquefied ammonia holding vessel is connected by conveying pipe successively, it is provided with remove impurity with active carbon structure in described liquefied ammonia bleacher, ammonia after ammonia compressor is cooled to liquefied ammonia after ammonia condenser, liquefied ammonia sloughs the oil in liquefied ammonia after the remove impurity with active carbon structure in liquefied ammonia bleacher, the impurity of phenol, last deposit to liquid ammonia storage tank.
This utility model, relative to prior art, has the advantage that and effect: flow process is simple, easy to operate, small investment.And when raw material sewage is hit, when raw material Oil in Sewage Water content, phenol content overproof and when bringing Ammonia purification system into, it can be ensured that the quality of liquefied ammonia is unaffected, still reaches Standard.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
In conjunction with accompanying drawing, the utility model will be further described by the examples below.The application is only further described by following example, should not be construed as the restriction to the application.
As shown in Figure 1, a kind of sewage stripping ammonia refining liquefied ammonia decoloration device, including apparatus main body, described apparatus main body includes ammonia condenser 1, liquefied ammonia bleacher 2, liquefied ammonia holding vessel 3, and according to ammonia condenser 1, liquefied ammonia bleacher 2, liquefied ammonia holding vessel 3 order successively by conveying pipe connect, ammonia after ammonia compressor is cooled to liquefied ammonia after ammonia condenser 1, liquefied ammonia sloughs the impurity of the oil in liquefied ammonia, phenol after the remove impurity with active carbon structure 4 in liquefied ammonia bleacher 2, is finally delivered to liquid ammonia storage tank 3 and deposits.And when raw material sewage is hit, when raw material Oil in Sewage Water content, phenol content overproof and when bringing Ammonia purification system into, it can be ensured that the quality of liquefied ammonia is unaffected, still reaches Standard.
Finally should be noted that: above example only in order to the technical solution of the utility model to be described, is not intended to limit；Although this utility model being described in detail with reference to previous embodiment, it will be understood by those within the art that: the technical scheme described in foregoing embodiments still can be modified by it, or wherein portion of techniques feature is carried out equivalent replacement；And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment technical scheme of this utility model.
