Description
Technical field
The utility model relates to a kind of spray purification system of acetic acid, and the acetic acid used in producing for PTA is purified.
Background technology
Need to use acetic acid in PTA production process and carry out production operation, and usually there is the lower phenomenon of purity in the acetic acid be placed on for a long time in storage tank, the acetic acid purity used when causing producing is inadequate, can not meet the demand of production, cause final production product quality out not up to standard.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides one to improve acetic acid purity, the spray purification system of the acetic acid improved the quality of products.
The purpose of this utility model is achieved in that
The spray purification system of the utility model acetic acid, comprise acetic acid tank, the sidewall of described acetic acid tank has two liquid outlets, be respectively the first liquid outlet and the second liquid outlet, described first liquid outlet is connected with dehydrating tower by pipeline, described second liquid outlet is connected with acetic acid spray column by pipeline, the liquid outlet of described dehydrating tower is connected with acetic acid tank by the first return duct, this first return duct is equipped with the first reflux pump, the dehydrating tower gas outlet of described dehydrating tower is connected by the bottom air inlet of pipeline with acetic acid spray column, this acetic acid spray column top has spray column gas outlet, the liquid outlet of acetic acid spray column is connected with acetic acid tank by the second return duct, this second return duct is equipped with the second reflux pump.
Compared with prior art, the beneficial effects of the utility model are:
The spray purification system of this acetic acid carries out gas-liquid separation by being passed in dehydrating tower by the acetic acid in acetic acid tank, acetic acid liquid after purification is back in acetic acid tank, gas then passes in acetic acid spray column and sprays, further acetic acid is purified, turn back to again in acetic acid tank, so just, improve the purity of the acetic acid in acetic acid tank, meet the demand of production, ensure that the quality of product.
Accompanying drawing explanation
Fig. 1 is the structural representation of the spray purification system of the utility model acetic acid.
Wherein: acetic acid tank 1, first liquid outlet 1.1, second liquid outlet 1.2, dehydrating tower 2, dehydrating tower gas outlet 2.1, first return duct 3, first reflux pump 4, acetic acid spray column 5, spray column gas outlet 5.1, second return duct 6, second reflux pump 7.
Detailed description of the invention
See Fig. 1, the utility model relates to a kind of spray purification system of acetic acid, comprise acetic acid tank 1, the sidewall of described acetic acid tank 1 has two liquid outlets, be respectively the first liquid outlet 1.1 and the second liquid outlet 1.2, described first liquid outlet 1.1 is connected with dehydrating tower 2 by pipeline, described second liquid outlet 1.2 is connected with acetic acid spray column 5 by pipeline, the liquid outlet of described dehydrating tower 2 is connected with acetic acid tank 1 by the first return duct 3, the first reflux pump 4 this first return duct 3 is equipped with, the dehydrating tower gas outlet 2.1 of described dehydrating tower 2 is connected by the bottom air inlet of pipeline with acetic acid spray column 5, this acetic acid spray column 5 top has spray column gas outlet 5.1, the liquid outlet of acetic acid spray column 5 is connected with acetic acid tank 1 by the second return duct 6, the second reflux pump 7 this second return duct 6 is equipped with.
The spray purification system of this acetic acid carries out gas-liquid separation by being passed in dehydrating tower 2 by the acetic acid in acetic acid tank 1, acetic acid liquid after purification is back in acetic acid tank 1, gas then passes in acetic acid spray column 5 and sprays, further acetic acid is purified, turn back in acetic acid tank 1 again, so just, improve the purity of the acetic acid in acetic acid tank 1, meet the demand of production, ensure that the quality of product.
