Abstract
The utility model relates to a kind of spray recovery system of tail gas, it is characterized in that: it comprises acetic acid spray column (2) and Water spray tower (6), described acetic acid spray column (2) is connected with tail gas discharging pipe (1), the top side wall of described acetic acid spray column (2) is connected with acetic acid feed tube (3), the bottom of described acetic acid spray column (2) is connected with drain pipe (4), the top of described acetic acid spray column (2) is provided with escape pipe (5), this escape pipe (5) is connected with the sidewall of Water spray tower (6), the top of the sidewall of this Water spray tower (6) is connected to water inlet pipe (7), the bottom of this Water spray tower (6) is drain pipe (8), top is connected with emission-control equipment (10) by exhaust emission tube (9).The spray recovery system of this tail gas reduces environmental pollution, decreases acetic acid waste, reduces production cost.
Description
Technical field
The utility model relates to a kind of spray recovery system of tail gas, to tail gas recycles in producing for PTA.
Background technology
With in remaining tail gas in PTA production process, containing a large amount of organic matters, containing a large amount of acetic acid in these organic matters, and these tail gas are generally just discharged in air after simple process, not only cause environmental pollution, also create the waste of acetic acid, thus make production cost higher.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of and reduces environmental pollution, decreases acetic acid waste, reduces the spray recovery system of the tail gas of production cost.
The purpose of this utility model is achieved in that
The spray recovery system of the utility model tail gas, comprise acetic acid spray column and Water spray tower, described acetic acid spray column is connected with tail gas discharging pipe, the top side wall of described acetic acid spray column is connected with acetic acid feed tube, the bottom of described acetic acid spray column is connected with drain pipe, the top of described acetic acid spray column is provided with escape pipe, this escape pipe is connected with the sidewall of Water spray tower, the top of the sidewall of this Water spray tower is connected to water inlet pipe, the bottom of this Water spray tower is drain pipe, and top is connected with emission-control equipment by exhaust emission tube.
Compared with prior art, the beneficial effects of the utility model are:
The spray recovery system of this tail gas sprays with acetic acid by being passed in acetic acid spray column by the tail gas containing a large amount of acetic acid, the most of acetic acid in tail gas is made to be incorporated in liquid, liquid containing acetic acid just can be passed in production system by drain pipe and use, and the gas containing acetic acid can enter escape pipe, and lead to continuation spray in Water spray tower, lead in emission-control equipment again removed the acetic acid in tail gas by Water spray tower after and process.So just, the waste of acetic acid can be reduced, reduce production cost, and can environmental pollution be reduced.
Accompanying drawing explanation
Fig. 1 is the structural representation of the spray recovery system of the utility model tail gas.
Wherein: tail gas discharging pipe 1, acetic acid spray column 2, acetic acid feed tube 3, drain pipe 4, escape pipe 5, Water spray tower 6, water inlet pipe 7, drain pipe 8, exhaust emission tube 9, emission-control equipment 10.
Detailed description of the invention
See Fig. 1, the utility model relates to a kind of spray recovery system of tail gas, comprise acetic acid spray column 2 and Water spray tower 6, described acetic acid spray column 2 is connected with tail gas discharging pipe 1, the top side wall of described acetic acid spray column 2 is connected with acetic acid feed tube 3 for down spraying acetic acid in acetic acid spray column 2, the bottom of described acetic acid spray column 2 is connected with drain pipe 4, this drain pipe 4 uses for being passed in production system by spray acetic acid liquid used, the top of described acetic acid spray column 2 is provided with escape pipe 5, this escape pipe 5 is connected with the sidewall of Water spray tower 6, the top of the sidewall of this Water spray tower 6 is connected to water inlet pipe 7 for down spraying water in Water spray tower 6, the bottom of this Water spray tower 6 is drain pipe 8, top is connected with emission-control equipment 10 by exhaust emission tube 9.
The spray recovery system of this tail gas sprays with acetic acid by being passed in acetic acid spray column 2 by the tail gas containing a large amount of acetic acid, the most of acetic acid in tail gas is made to be incorporated in liquid, liquid containing acetic acid just can be passed in production system by drain pipe 4 and use, and the gas containing acetic acid can enter escape pipe 5, and lead to continuation spray in Water spray tower 6, lead to again in emission-control equipment 10 removed the acetic acid in tail gas by Water spray tower 6 after and process.So just, the waste of acetic acid can be reduced, reduce production cost, and can environmental pollution be reduced.
