The specific embodiment
Embodiment 1
Gas-liquid separator air inlet is connected with fermentation tank blast pipe, and in exhaust outlet access tail gas washing tower, tail gas washing tower is placed on factory building roof.
Gas-liquid separator adopts the Special gas-liquid separator in this device systems;
Tail gas washing tower has adopted the tail gas washing tower that the patent No. is 201220230187.0.
Operating procedure is as follows:
When 1, fermentation tank is started working, open automatic switch valve I3, according to the requirement of the throughput of fermentation tank and tank internal pressure, automatically regulate the open degree of the control valve 2 on blast pipe, make tolerance and the air inflow balance of discharge, maintain the required pressure of fermentation tank;
2, the fermentation tail gas that is entrained with a large amount of liquid foams enters gas-liquid separator 1, along tangent line, enter the gas-liquid two-phase material of cylindrical shell, move in a circle at a high speed, enter after spiral stream guidance band, along diversion belt, spin and move, in screw process, effect by centrifugal force, oarse-grained liquid gets rid of to barrel, and a part drops along the gap between diversion belt and barrel, and another part is along diversion belt landing; Granule drop continues along diversion belt with flow rotation, and progressively separated, until diversion belt end;
Liquid after separation is gone under cone, by leakage fluid dram, discharges; The gas velocity of backspin reduces gradually, arrives whirlpool arrester rear steering up, from exhaust outlet, is discharged to tail gas washing tower 4.
The whirlpool arrester of cone base has effectively stoped the rotation of air-flow, avoids separating and be gathered in the liquid of bottom or air-flow that liquid foam is risen and again takes away;
3, before tail gas enters scrubbing tower, first open alkali lye supply pump 11, the alkali lye that is 5% by the concentration preparing is got in the lye tank (vat) 5 of scrubbing tower bottom, stand-by after automatic-closing valve II6 after the liquid level setting in reaching groove;
4, when starting to ventilate, opens by fermentation tank the alkali lye spray pump 8 of scrubbing tower, make to enter tail gas and alkali lye gas-liquid two-phase reverse Continuous Contact in filler of scrubbing tower, realize mass transfer, gas scrubbing operation, the alkali lye of spray is taken back lye tank (vat) 5 by the mist in tail gas, also killed the viable bacteria that tail gas is carried secretly, clean gas drains into atmosphere by scrubbing tower top evacuation port simultaneously; Valve IV7 is normally open valve door, the impurity of piping filter 13 in can elimination alkali lye.
5, after fermentation ends, close alkali lye spray pump 8, open valve III9 on lye tank (vat) 5 discharge pipes of scrubbing tower bottom, alkali lye is discharged in recycle of alkali liquor tank 10.When liquid level gauge measure alkali lye all emptying after, automatic-closing valve III9, waits for charging next time.
6, the foam liquid that the alkali liquid washing that recycle of alkali liquor tank 10 reclaims gets off can be deposited to the bottom of tank, and for preventing that sediment from being got in scrubbing tower bottom lye tank (vat) 5 again, recycle of alkali liquor tank 10 exit positions are arranged on the direct tube section bottom of tank, and sediment is not drawn out of.Recycling can minimum point is established blowdown switch valve V12, until sediment run up to a certain amount of after, open switch valve V12, discharge sediment.
After the invention process, final tail gas Exhaust Gas particle≤0.5 micron, mist and viable bacteria clearance reach 99%.
Native system is processed tail gas amount can be at 400m3/h～12000m3/h.
