Abstract
The invention provides an industrial exhaust gas fine washing device, relating to the industrial exhaust gas cleaning field. A U-shaped pipe is arranged between equipment (5) and equipment (6), a U-shaped pipe is arranged between the equipment (6) and equipment (7), a U-shaped pipe is arranged between the equipment (7) and equipment (8), the requirement on the liquid level of an absorbing medium in each equipment is met, and the absorbing medium passes through the equipment (5), the equipment (6), the equipment (7) and the equipment (8) sequentially by potential difference from an absorbing medium inlet and is finally drained from an absorbing medium opening (4). Steam ammonia in exhaust gas is recovered for four times, so that the recovery rate of steam ammonia in exhaust gas produced by urea production is improved, the consumption during production process is reduced, and the emission of harmful industrial exhaust gas is reduced. The equipment is in horizontal design, the four pieces of equipment are stacked in place and the installation is convenient.
Description
Technical field:
The present invention relates to a kind of industrial tail gas fine purifiation device.
Background technology:
In urea production, adopt once washing absorption process to reclaim rear tail gas emptying to the vapour ammonia in tail gas, recovering effect is poor, causes to produce to consume greatly, pollutant atmosphere.
Summary of the invention:
The object of this invention is to provide a kind of industrial tail gas fine purifiation device, what it realized vapour ammonia in tail gas by one group of equipment reclaims for four times, improves the rate of recovery of vapour ammonia in urea production process tail gas.
In order to solve the problem existing for background technology, the present invention is by the following technical solutions: industrial tail gas is successively by 5,/6/,7/8 4 equipment, and carry out fully contacting with the absorbing medium in equipment the absorption reached vapour ammonia in tail gas, final tail gas enters air.Absorbing medium in absorption process in 5/,6/7 three equipment keeps certain liquid level by U-tube.The heat produced in absorption process is removed by cooling water by the heat exchanger tube in equipment.Equipment in technique is pressure vessel, and 5/,6/7 three device structure is identical.
The following beneficial effect of tool of the present invention:
1, the consumption of production process is reduced.
2, the discharge of noxious industry tail gas is reduced.
3, the rate of recovery of vapour ammonia in urea production process tail gas is improved.
Accompanying drawing illustrates:
Fig. 1 is flow chart of the present invention.
Detailed description of the invention:
With reference to Fig. 1, industrial tail gas, is finally discharged from offgas outlet 2 from inlet exhaust gas 1 successively by equipment 5, equipment 6, equipment 7, equipment 8.Be provided with U-tube between equipment 5 and equipment 6, between equipment 6 and equipment 7, be provided with U-tube, between equipment 7 and equipment 8, be provided with U-tube, ensure the requirement of equipment absorbing medium liquid level.Absorbing medium passes through equipment 8, equipment 7, equipment 6, equipment 5 from absorbing medium import 3 successively by potential difference, finally discharges from absorbing medium outlet 4.Equipment is horizontal design, and four equipment stack in place, is convenient to install.
