The specific embodiment
The utility model comprise air shooter 4, in and container, neutralizer leak shower device 10.Said air shooter 4 is fluorine plastic tubes of diameter 10～30mm, during the chlorine-containing gas that gas collector is collected is transported to the bottom of container.
In said with container by airtight fluoroplastics jar 1, spongy demarcation strip 2, neutralizer 3 and in and leveling device 6 constitute.The cylindrical tank that said airtight fluoroplastics jar is the fluoroplastics material, spongy demarcation strip 2 is distributed in the middle part of tank body, and fluoroplastics tank body 1 is separated into the multilayer separate space; As preferred version, said spongy demarcation strip 2 has four at least, is respectively the spongy demarcation strip of the spongy demarcation strip of ground floor 21, the second layer 22, the 3rd layer spongy demarcation strip 23, the 4th layer of spongy demarcation strip 24.Separate each other and substantially parallel, the thickness of every spongy demarcation strip 2 is 50～200mm, and the top of the 4th layer of spongy demarcation strip 24 of the superiors and the distance of container top are greater than 70mm.Said spongy demarcation strip 2 is made up of its hole＜0.5mm exactly sponge and analog thereof.
Said neutralizer 3 is an alkaline solution, and as preferred version, said neutralizer 3 is 10～30% NaOH solution.
With leveling device 6, be to be arranged at one section outside plastic tube of plastic containers in said, the one of which end communicates with fluoroplastics jar 1 bottom; The other end leaks shower device with neutralizer and links to each other; Its diameter is at 10～30mm, and height is at 100～300mm, and this has highly controlled the liquid level of neutralizer in the fluoroplastics jar 1; Make that the spongy demarcation strip 21 of undermost ground floor is immersed in the neutralizer 3 in the jar; Neutralizer 3 liquid levels are in case surpass this height, unnecessary neutralizer 3 just by in derive tank bodies with leveling device 6, flow in the neutralizer leakage shower device.
Said neutralizer leaks shower device by liquid storing barrel 7, liquid transporting apparatus 9 and leak shower device 10 and constitute, and liquid storing barrel 7 is an airtight Plastic Drum, accept by in the neutralizers 3 of constantly deriving with leveling device 6; Liquid transporting apparatus 9 is made up of lye pump and plastic flexible pipe, and flexible pipe one end connects liquid storing barrel 7, and the other end connects and leaks shower device 9, under the lye pump effect, constantly neutralizers 3 in the liquid storing barrel 7 is transported in the shower device 9 with Louing, neutralizer 3 is formed circulate.
Said leakage shower device 10, be base plate be evenly distributed with said minuscule hole, flattened cylindrical opaque container, be installed in airtight in the container the superiors; The base plate hole diameter is at 0.5～1.5mm; Porosity accounts for 20～30% of surface area; Height is at 15～30mm, and by the neutralizer 3 of liquid transporting apparatus 9 inputs, shower device 10 base plate apertures are even, floor drain drenches in the spongy demarcation strip 21 of ground floor of lower floor continuously through leaking.
In the utility model with container in the pH value of NaOH solution should remain on more than 7.2, when dropping to 7.2 when following, then need change NaOH solution.For in monitoring with container in the pH value; The applicant is provided with pH acidometer 8 on the liquid storing barrel 7 of neutralizer leakage shower device; When the pH of solution value drops to 7.2 when following, at first change the neutralizer 3 in the liquid storing barrel 7, along with fresh neutralizer 3 is progressively replaced neutralizers 3 in neutralizers 3 in the 4th layer spongy demarcation strip 24, the 3rd layer spongy demarcation strip 23 through leaking shower device 10 ... Up in container in the neutralizer 3 of bottom be replaced, reach in the replacing with container in the purpose of NaOH solution.As preferred version, the utility model adopts two cover chlorine-containing gas neutralizing tanks, when the neutralizer pH of a cover drops to 7.2 when following, use another set of neutralizing tank, and the neutralizing tank under will changing is cleared up, and neutralizer is changed, and is subsequent use.
For the ease of using; The applicant in container top steam vent 12 is set; The 4th layer of spongy demarcation strip 24 and neutralizer that steam vent 12 is arranged on the superiors leak between the shower device, and chlorine probe 11 is set near steam vent 12, arrive the gas of neutralisation treatment its upper side; After 11 monitorings of chlorine probe are up to standard, discharge from steam vent.
The course of work of the utility model is:
Chlorine-containing gas through air shooter 4 import to be equipped with NaOH solution in and container bottom; Chlorine-containing gas is from the bottom makes progress flotation process; Spongy demarcation strip 2 resolves into chlorine-containing gas＜micro-bubble of 1mm; Owing to be full of NaOH solution in the small hole of sponge, resolved into by sponge in the micro-bubble process at chlorine-containing gas, the NaOH in the sponge is directly and the Cl in the chlorine-containing gas
2Neutralization reaction fast and efficiently takes place, and does not resemble the Cl in the bubble
2, on the interface of bubble and solution neutralization reaction takes place only, this just is equivalent to the Cl in the chlorine-containing gas
2Carried out fine filtering one time.
As preferred version; The utility model adopts at least four spongy demarcation strips 2; Wherein one of foot is immersed in the neutralizer 3, its excess-three piece be uniformly distributed in airtight in container in, the top of the 4th layer of spongy demarcation strip 24 of the superiors and the distance of container top are greater than 70mm.Because 3 of neutralizers have soaked the spongy demarcation strip 21 of undermost ground floor, during so only the less discharge pressure of needs just can be transported to chlorine-containing gas and the bottom of container.When chlorine-containing gas through orlop, be immersed in spongy demarcation strip 2 neutralization in the neutralizer 3, resolve into tiny bubble after; The continuation certain distance that in NaOH solution, rises, migrates; Again in air, assemble then, rise; When running into inside once more and be full of the spongy demarcation strip 2 of NaOH solution, chlorine-containing gas is decomposed equally, contained Cl
2By neutralization fast and efficiently, be equivalent to again this gas has been carried out once meticulous Cl
2Filter, make the better effects if of neutralisation treatment chlorine-containing gas.Such process only needs repetition four times for the lower gas of chlorinity, repeats possibly five times even more for the higher gas of chlorinity, and promptly spongy demarcation strip 2 is wanted five layers even more, and this can confirm different Cl through experiment
2Which floor spongy demarcation strip 2 gas of concentration needs, certainly, also can reach effectively through the thickness that increases spongy demarcation strip 2 in and Cl
2Effect; Reach the gas of neutralisation treatment its upper side at last, chlorine gas concentration＜1mg/m wherein
