Abstract
The utility model discloses a kind of black water treatment system intermediate pump exhaust gas processing device, including vacuum pump system, vacuum pump system is provided with tail gas discharging pipe, also include injector, medium input pipe and flash tank, tail gas discharging pipe is connected with injector, medium input pipe is connected with injector, and flash tank connects with gun hose；So the tail gas of vacuum pump system is under injector suction function, rapidly enter injector, mixed simultaneously with medium input pipe mesohigh steam or high pressure buck, rapidly input storage or further processing in flash tank, the tail gas of vacuum gas pump processing unit is set without special supercharging power, is made full use of the pressure that steam or buck automatically generate in gasification installation, is reached tail gas pressurized effect, equipment investment is small, and operation costs are low.
Description
Technical field
It the utility model is related to black water treatment system, and in particular to a kind of black water treatment system intermediate pump vent gas treatment dress
Put.
Background technology
In gasification installation, black water treatment system is to from gasification furnace, slag inclusion pond and synthesis gas washing and treated
Caused Heisui River or the workshop section handled containing pulp water in journey, using multi-stage flash process to reach to sour gas solution in pulp water
Inhale, the purpose of Heisui River concentrate cooling.The black water treatment system flash distillation sum of series parameter of different process can difference, usual final stage
It is vacuum pump system that flash tank negative pressure, which produces equipment,（Vavuum pump, condenser, knockout drum combination）, to vacuum pumped
Gas carries out lime set separation.Tail gas is to export discharge from the top gas phase of vacuum pump system, and it is mainly formed as CO2And H2O, with
And a small amount of H2, CO, H2S, it is minimum that tail gas is mainly characterized by flow（Usually 0 ~ 20kg/h）, pressure it is extremely low（Usually normal pressure or
Tiny structure）.But have at present to vent gas treatment：Sulfur recovery facility or alkali liquid washing are delivered in discharge, high point emptying, pressurization on the spot
Method.Discharge can turn into persistent pollution sources on the spot, and serious threat is caused to staff's health.Although high point emptying environmental protection,
But it is pressurized power setting and pipeline cost is big, equipment investment is big, and operation costs are high.Sulfur recovery facility is delivered in pressurization, is also needed specially
The supercharging power of door sets supercharging, and equipment investment is big, and operation costs are high.Alkali liquid washing method assimilation effect is unstable, and alkali lye is changed
Frequently, the labor intensity of operating personnel is not only increased, the problem of solvent saturated process also be present, easily cause secondary pollution.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of black water treatment system intermediate pump vent gas treatment dress
Put, the tail gas of vacuum gas pump processing unit is set without special supercharging power, and operation costs are low, and effect is good, and simple to operate.
Technical scheme is used by the utility model solves above-mentioned technical problem：A kind of black water treatment system intermediate pump
Exhaust gas processing device, including vacuum pump system, the vacuum pump system are provided with tail gas discharging pipe, in addition to injector, medium are defeated
Enter pipe and flash tank, the tail gas discharging pipe is connected with the injector, and the medium input pipe is connected with the injector, institute
Flash tank is stated to connect with the gun hose.
Column plate is provided with the flash tank, its number of plates is 2-15 blocks.
The flash tank is provided with gaseous phase outlet.
The medium input pipe is provided with compression pump.
The medium input pipe is provided with pressure regulator valve.
Compared with prior art, the utility model has the advantage of a kind of black water treatment system intermediate pump vent gas treatment dress
Put, including vacuum pump system, vacuum pump system are provided with tail gas discharging pipe, in addition to injector, medium input pipe and flash tank, tail
Gas delivery pipe is connected with injector, and medium input pipe is connected with injector, and flash tank connects with gun hose；Such vacuum pump system
Tail gas under injector suction function, rapidly enter injector, at the same with medium input pipe mesohigh steam or high pressure buck
Mixing, storage or further processing in flash tank are rapidly input, the tail gas of vacuum gas pump processing unit is without special supercharging power
Setting, make full use of the pressure that steam or buck automatically generate in gasification installation, reach tail gas pressurized effect, equipment investment is small,
Operation costs are low.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing embodiment.
Embodiment 1
A kind of black water treatment system intermediate pump exhaust gas processing device as shown in Figure 1, including vacuum pump system 1, vacuum

Compression pump 3 and pressure regulator valve 4, flash tank 6 is interior to be provided with column plate（Do not shown in figure）, its number of plates is 2-15 blocks, tail gas discharging pipe 12
It is connected with injector 5, medium input pipe 2 is connected with injector 5, and flash tank 6 connects with the pipe of injector 5, and flash tank 6 goes out provided with gas phase
Mouthfuls 61 and provided with gray water outlet 62.The input of medium input pipe is buck, as injector pressure power source, will come from vavuum pump
System temperature is 0 DEG C ~ 100 DEG C, and pressure be -80 ~ 100KPaG, the tail gas that flow is 0 ~ 50kg/h aspirates and is forced into 0.3 ~
2.0MPaG, compression pump can pressurize buck to 0.8 ~ 4.0MPaG, and pressure size is by pressure regulation valve regulation.Injector sprays including gas
Penetrate compressor reducer, gas ejector, gas ejector, jet pump, Geldart-D particle injector, water-air injector, Hydraulic transportation spray
Emitter etc., according to being actually needed selection.
Embodiment 2
Substantially the same manner as Example 1, what different simply medium input pipes inputted is water vapour.
