Specific implementation mode
As shown in Figs 1-4, a kind of tail gas washing tower using gas-liquid separation membrane, by tower body 1 and consolidating positioned at 1 lower section of tower body
Determine portion 2 composition, tower body 1 include be located above the top 11 in circular arc lid, positioned at lower section in circular arc lid bottom 13 and
In the middle part 12 of hollow tube-shape between top 11 and bottom 13；By being welded to connect between middle part 12 and bottom 13, to protect
Bonding strength and tower body inner sealing are demonstrate,proved, is connected by sticking department 1g between middle part 12 and top 11, in order to which the later stage is logical
It crosses the gas-liquid separation membrane that sticking department 1g is opened inside the 11 pairs of tower bodies in top and carries out replacement maintenance；The inside of tower body 1 is by from top
11 the first seperation film 1j, the second seperation film 1k and the third seperation film 1l set gradually to bottom 13 separate to be escaped for top
Chamber 1m, the first disengagement chamber 1n, the second disengagement chamber 1p and bottom deposit chamber 1q；First seperation film 1j, the second seperation film 1k and
Third seperation film 1l respectively includes outer flat bed i1, interior concave layer i3 and the transition zone for connecting outer flat bed i1 and interior concave layer i3
I2, interior concave layer i3 are provided with guide protrusions i31 in a circle in center location and center of circle periphery, and outer flat bed i1 is circumferentially uniformly distributed
There is the outer guide protrusions i11 of multi-turn, a plurality of drainage trough i21 is circumferentially provided in transition zone i2 upper edges, interior guide protrusions i31 and leads outside
It is set as parabola shaped to the raised sections i11, is offered in the center location of interior guide protrusions i31 and outer guide protrusions i11 fair
Perhaps liquid by through-hole, offering on the first seperation film 1j, the second seperation film 1k and third seperation film 1l allows gas logical
Cross but do not allow liquid by micropore so that the gas after washing is successively escaped up by seperation film, and cleaning solution
After successively collecting flowing downwards and participating in washing, then it is pooled to lower section and is discharged eventually by outlet 1d.
Specifically, the section of the first seperation film 1j, the second seperation film 1k and third seperation film 1l are set as inner cone concave station
Shape in order to which cleaning solution successively collects downwards flowing, while increasing the contact area with gas, to improve gas effusion effect
Rate.
Specifically, outer flat bed i1 is circumferentially in the outer guide protrusions i11 of uniformly distributed multi-turn, the outer guide protrusions of two adjacent rings
I11 is staggered in the circumferential, to avoid the formation of liquid linear runner as far as possible, to avoid cleaning solution on outer flat bed i1
It is excessive to collect flowing to influence gas effusion effect, be conducive to liquid and fallen at dripping.
Specifically, 12 side of middle part of tower body 1 offers air inlet 1b for being passed through impure tail gas to be washed, tower body
1 12 other side of middle part offers cleaning solution import 1a for being passed through cleaning solution for washing tail gas, the middle part 12 of tower body 1 remove into
Gas port 1b, the positions cleaning solution import 1a the other side be further opened with liquid level gauge erection joint 1e and lower liquid level gauge installation connect
Head 1f for detecting 1 inside liquid level of tower body, 11 top of top of tower body 1 offer gas outlet 1c for be discharged it is washed after tail
13 lower section of bottom of gas, tower body 1 offers outlet 1d for being discharged when the cleaning solution after washing stockpiles excessive in tower body.
Specifically, tower body 1 radially, the axis direction of cleaning solution import 1a and the axis direction of air inlet 1b are in straight
Angle is arranged, and increases the cleaning solution of entrance and the contact surface area of air, at the same vertically to contact it is mixed convenient for cleaning solution and tail gas
Circulation or vortex are formed after conjunction, so that the two, which comes into full contact with, further increases washing effect, upper liquid level gauge erection joint 1e
Overlapped with the positions lower liquid level gauge erection joint 1f and axis direction be located at the axis direction of cleaning solution import 1a into 150 degree and
The axis direction of air inlet 1b is on 120 degree of position so that in upper and lower liquid level gauge detection tower body the liquid level position of the same face with
Improve relative accuracy.
Specifically, cleaning solution import 1a and upper liquid level gauge erection joint 1e are located at sustained height so that when detecting upper liquid
When position is transfinited, cleaning solution inlet can be controlled in time, lower liquid level gauge erection joint 1f is located at cleaning solution import 1a and upper liquid level
It counts below erection joint 1e, the amount for detecting the liquid for participating in being left after washing is discharged when transfiniting by outlet 1d, into
Positions of the gas port 1b between upper liquid level gauge erection joint 1e and lower liquid level gauge erection joint 1f.
Specifically, 12 outside of middle part of tower body 1 is additionally provided with observation window 1h, consequently facilitating recognizing tower body in time from outside
Internal washing situation in real time.
Specifically, fixed part 2 is provided with 3 along the radial direction of tower body 1, and fixed stability, Mei Gegu are supported to improve
Determine portion 2 to include the partition board 21 for fitting in 1 outer wall of tower body, baffle 24, be set to inside the angle that partition board 21 is surrounded with baffle 24
Supporting rack 22 and the support base 23 for being fixed on 22 lower section of supporting rack, partition board 21 are outer for being connected and fixed, moreover it is possible to realize heat-insulated work
With to ensure that 1 internal temperature of tower body is constant, baffle 24 can also play exterior protection work for being connected and fixed supporting rack 22
With.
When specific works, tail gas to be washed enters from air inlet 1b in tower body 1, and cleaning solution enters tower from cleaning solution import 1a
The second disengagement chamber 1p inside body 1 is sufficiently mixed with tail gas to be washed, and the tail gas after washing passes through the second seperation film successively
Micropore, the first disengagement chamber 1n on 1k, the micropore on the first seperation film 1j, top escape chamber 1m, and eventually by gas outlet 1c
Discharge, and escaping gas successively pass through the second disengagement chamber 1p, the first disengagement chamber 1n inside cleaning solution washing, impure rate into
One step reduces, and institute's water content in gas and cleaning solution, by the isolation of two separate film, separating effect is more preferably；It participates in washed
Cleaning solution after journey passes through the first disengagement chamber 1n, the through-hole on the second seperation film 1k, the second disengagement chamber 1p, third seperation film successively
Through-hole on 1l eventually enters into bottom deposit chamber 1q, and peace holds liquid level gauge and detects on the 1f of liquid level gauge erection joint instantly
After the used cleaning solution of deposition reaches threshold deposition, outlet 1d discharges are opened；Pacify when on upper liquid level gauge erection joint 1e
The upper liquid level gauge of dress detects that the cleaning solution of entrance reaches into after threshold value, close cleaning solution import 1a stop cleaning solution into
Enter.
In addition to above example, the present invention can also have other embodiment, not repeat one by one herein.Use in every case etc.
With replace or equivalent transformation formed technical solution, belong to the present invention claims protection domain.
