Abstract
The utility model discloses a device capable of absorbing ammonia gas in purge gas by copper liquid, which comprises an absorption tower and a gas-liquid separator, wherein the upper portion of the absorption tower is connected with a pump body, the bottom portion of the absorption tower is equipped with a gas inlet and the side wall of the absorption tower is equipped with a liquid outlet. The absorption tower of the device is connected with the pump body, the renewable copper liquid is used as a absorbent and sent into the absorption tower from the top portion of the absorption tower by the pump body, purge gas which is richly contained with ammonia gas and comes from an ammonia storing tank in synthetic ammonia production enters the absorption tower from the bottom portion of the absorption tower, and contacts with copper liquid in countercurrent form sent by the pump body on the packing layer inside the absorption tower. After absorbing, the copper liquid removes harmful gas such as CO in purge gas and then is sent to the next system to use. The purge gas being absorbed contains only about 0.8% ammonia gas, which can be directly sent to a blower and used for combustion. The device has simple structure and high energy utilizing rate, is free of washing process, and greatly saves energy.
Description
Technical field
The utility model relates to a kind of ammonia retracting device, relates in particular to the device that a kind of copper liquid absorbs ammonia in the off-gas.
Background technology
The content of ammonia is generally about 55% in the off-gas in the ammonia storage tank of chemical plant synthesis ammonia system, at present, ammonia enterprises such as most of chemical fertilizer factories are directly sent into off-gas in the blowing-out gas combustion furnace, ammonia is not reclaimed, the enterprise that has directly is discharged into this part gas in the atmosphere, not only caused waste, and severe contamination environment.
The utility model content
The purpose of this utility model is to provide a kind of copper liquid to absorb the device of ammonia in the off-gas, with the ammonia in its off-gas of effective recovery.
To achieve these goals, the technical solution of the utility model has adopted a kind of copper liquid to absorb the device of ammonia in the off-gas, comprises absorption tower, gas-liquid separator, is connected with a pump housing on top, absorption tower, be provided with air inlet in the bottom, absorption tower, sidewall is provided with liquid outlet.
The described pump housing is a plunger displacement pump.
Described separator is connected with the top on absorption tower by pipeline.
In the absorption tower, be provided with packing layer.
Be connected with a pump housing on the absorption tower of the present utility model, copper liquid after the regeneration is as absorbent, be admitted in the absorption tower from the top, absorption tower by the pump housing, the off-gas that is rich in ammonia that ammonia storage tank in the Ammonia Production comes is entered in the absorption tower by the bottom, absorption tower, the copper liquid counter current contacting that the packing layer in the absorption tower and the pump housing are sent here, after copper liquid after the absorption is removed pernicious gases such as CO in the off-gas, be admitted to the utilization of next system, ammonia only is about 0.8% in the off-gas after the absorption, directly delivers to blowing-out gas and uses for burning.Of the present utility model simple in structure, the capacity usage ratio height, and do not have the washing process, saved the energy greatly.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, copper liquid of the present utility model absorbs the device of ammonia in the off-gas, comprises absorption tower 1, gas- liquid separator 2, and 1 top is connected with a plunger displacement pump 3 on the absorption tower, and 1 bottom is provided with air inlet 4 on the absorption tower, and sidewall is provided with liquid outlet 5.Gas-liquid separator 2 is connected by the top of pipeline 6 with absorption tower 1, is provided with packing layer 7 in absorption tower 1.
Copper liquid after the regeneration of the utility model usefulness is as absorbent, be admitted in the absorption tower 1 from 1 top, absorption tower by plunger displacement pump 3, the off-gas that is rich in ammonia that ammonia storage tank in the Ammonia Production is sent here is entered in the absorption tower 1 by the air inlet 4 of 1 bottom, absorption tower, the copper liquid counter current contacting that packing layer 7 in absorption tower 1 and plunger displacement pump 3 are sent here, copper liquid behind the absorption ammonia enters into a next system and is utilized, only contain ammonia about 0.8% in the off-gas after the absorption in the gas of ammonia behind gas-liquid separator 2, directly delivered to blowing-out gas and use for burning.
