Description
Technical field
The utility model relates to a kind of spray recovery system of tail gas.
Background technology
With in remaining tail gas in the production process of p-phthalic acid, 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, and decrease acetic acid waste, using water wisely, 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, top is connected with emission-control equipment by exhaust emission tube, the spray recovery system of this tail gas also comprises jet chimney and steam spray column, the top of described jet chimney is connected with steam jet pump rear end, the bottom of jet chimney is connected with the foot of steam spray column side, described steam spray column inside is provided with multiple shower tray from top to bottom, spray apertures is had bottom shower tray, described shower tray is fixed on the inwall of steam spray column, the bottom of described steam spray column is connected with return pipe, this return pipe is connected with the water inlet at steam spray column top, the topmost of the side of described steam spray column has steam (vapor) outlet, described steam (vapor) outlet is connected with by the water inlet pipe of heat exchanger with Water spray tower.
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; Spray shower water used is the high-temperature steam condensation used by production equipment simultaneously, has saved with water, has reduced production cost.
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, jet chimney 11, steam spray column 12, shower tray 13, return pipe 14, steam (vapor) outlet 15, heat exchanger 16.
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 also comprises jet chimney 11 and steam spray column 12, the top of described jet chimney 11 is connected with steam jet pump rear end, the bottom of jet chimney 11 is connected with the foot of steam spray column 12 side, described steam spray column 12 inside is provided with multiple shower tray 13 from top to bottom, spray apertures is had bottom shower tray 13, described shower tray 13 is fixed on the inwall of steam spray column 12, the bottom of described steam spray column 12 is connected with return pipe 14, this return pipe 14 is connected with the water inlet at steam spray column 12 top, for periodical feeding, the topmost of the side of described steam spray column 12 has steam (vapor) outlet 15, described steam (vapor) outlet 15 is connected with the water inlet pipe 7 of Water spray tower 2 with by heat exchanger 16.
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.
Spray shower water used is the high-temperature steam condensation used by production equipment simultaneously, passes in Water spray tower 6 and use after steam spray column and heat exchanger, has so just saved with water, has reduced production cost.
