In addition, in the production process of Coal Chemical Industry industry, also used degassing vessel equipment, it is mainly used in oxygen in the water and non-condensable gas is removed.In use; The water that will contain oxygen and non-condensable gas is passed in the degassing vessel; And in this degassing vessel, feed steam, and make steam and water carry out heat exchange and oxygen in the water and non-condensable gas are removed, can also play the purpose that adds hot water; Water is expelled to the Coal Chemical Industry production line from degassing vessel and uses then, and noncondensable gas is then discharged from the degassing vessel top.In expellant gas, except containing non-condensable gas, also contain the steam that part does not have condensation to get off, cause this part steam discharge and heat energy is not fully used.
The utility model content
The utility model technical problem to be solved provides a kind of condensate recovery system that reduces the gas stripping column energy consumption.
The utility model solves the technical scheme that its technical problem adopted: condensate recovery system; Comprise gas stripping column; Gas stripping column is provided with condensing water inlet pipeline, water of condensation recovery channel, nitrogen inlet pipeline, steam-in pipeline and gas exhaust duct, and said steam-in pipeline is connected with degassing vessel.
Further be that said water of condensation recovery channel is connected with degassing vessel.
Further be, comprise that also steam replenishes pipeline, the end that said steam replenishes pipeline communicates with gas stripping column, and the other end communicates with degassing vessel, and steam replenishes on the pipeline and is connected with external steam-pipe.
Further be that steam replenishes pipeline and is provided with variable valve.
Further be; In gas stripping column, be provided with the mass-and heat-transfer internals; Said condensing water inlet pipeline and gas exhaust duct are arranged on mass-and heat-transfer internals top, and an end, water of condensation recovery channel, nitrogen inlet pipeline and steam-in pipeline that the additional pipeline of said steam communicates with gas stripping column all are arranged on mass-and heat-transfer internals below.
The beneficial effect of the utility model is: because the steam-in pipeline connects degassing vessel, can remove the sour gas in the water of condensation, the steam of discharging in the degassing vessel is fully used, reduce steam consumption, can cut down the consumption of energy greatly; And the water of condensation recovery channel is connected with degassing vessel, can the water of discharging in the water of condensation recovery channel further be recycled, and can in degassing vessel, further heat, be adapted at process condensate water recycling occasion and apply.
Description of drawings
Fig. 1 is the system construction drawing of the utility model.
Be labeled as among the figure: gas stripping column 1, condensing water inlet pipeline 2, water of condensation recovery channel 3, nitrogen inlet pipeline 4, steam-in pipeline 5, degassing vessel 6, mass-and heat-transfer internals 7, gas exhaust duct 8, steam replenish pipeline 9, external steam-pipe 10, variable valve 11.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
As shown in Figure 1; The condensate recovery system of the utility model; Comprise gas stripping column 1, gas stripping column 1 is provided with condensing water inlet pipeline 2, water of condensation recovery channel 3, nitrogen inlet pipeline 4, steam-in pipeline 5 and gas exhaust duct 8, and said steam-in pipeline 5 is connected with degassing vessel 6.During work; Water of condensation from the conversion section final separator gets in the gas stripping column 1 from condensing water inlet pipeline 2; Nitrogen gets in the gas stripping column 1 from nitrogen inlet pipeline 4, and steam in steam-in pipeline 5 enters into gas stripping column 1, makes that the sour gas in the water of condensation is deviate from from degassing vessel 6 under the effect of nitrogen and LP steam; And from gas exhaust duct 8 discharges, condensate temperature after treatment raises and recycles from 3 outflows of water of condensation recovery channel.This mode can remove the sour gas in the water of condensation, and the steam of discharging in the degassing vessel 6 is fully used, and can reduce steam consumption, can cut down the consumption of energy greatly.
In order to handle the water of discharging in the water of condensation recovery channel 3, said water of condensation recovery channel 3 is connected with degassing vessel 6 again.Like this, the water of from water of condensation recovery channel 3, discharging can enter into degassing vessel 6 and further recycle, and can in degassing vessel 3, further heat.
When the steam of degassing vessel 6 discharges can not satisfy the needs of gas stripping column 1; In order in gas stripping column 1, to replenish steam; The condensate recovery system of the utility model comprises that also steam replenishes pipeline 9; The end that said steam replenishes pipeline 9 communicates with gas stripping column 1, and the other end communicates with degassing vessel 6, and steam replenishes on the pipeline 9 and is connected with external steam-pipe 10.Like this, external steam can get in the gas stripping column 1 through external steam-pipe 10 and through the additional pipeline 9 of steam; In addition, also communicate, also replenished steam in the degassing vessel 6 in the past with degassing vessel 6 because steam replenishes pipeline 9.
Stable in order to guarantee the WP in the degassing vessel 6, steam replenishes pipeline 9 and is provided with variable valve 11.Regulate the quantity of steam that gets in gas stripping column 1 and the degassing vessel 6 through this variable valve 11, thereby guarantee the pressure-stabilisation and the works better of degassing vessel 6.
