Detailed description of the invention
If Fig. 1 is structural representation of the present utility model, a kind of trimethylamine waste gas pollution control and treatment system, to be linked in sequence by pipeline by trimethylamine stockline 9, tail gas absorption house steward 10, twice water absorption tower 1, blower fan 1, twice acid absorption column 2, low-temperature plasma equipment 6, blower fan 2 72 and to form the basic cleaning system of gas;
Water tourie 4 is established below described twice water absorption tower 1, water tourie 4 is connected with distilation equipment 3, sour tourie 5 is established below described twice acid absorption column 2, in acid tourie 5, liquid passes into distilation equipment 3 after adjust pH, water lotion, the tail gas of pickle after distilation equipment 3 distills of water tourie 4 and sour tourie 5 enter twice water absorption tower 1 again, trimethylamine liquid after distilation equipment 3 distills enters trimethylamine stockline 9 again, forms the recirculation cleaning system of gas.
As shown in Figure 2, connect mutually in twice water absorption tower 1, is provided with three layers of filler 11 in per pass water absorption tower 1, and be equipped with spray head 12 above every layer of filler 11, can ensure that spray liquid sprawls into liquid film at filling surface, and liquid film Surface Renewal is rapid.Top, water absorption tower 1 is provided with dehydrating unit 13, can dehumidify, be convenient to subsequent treatment process.
As shown in Figure 3, twice acid absorption column 2 is connected mutually, is provided with three layers of filler 21 in per pass acid absorption column 2, and is equipped with spray head 22 above every layer of filler 21, can ensure that spray liquid sprawls into liquid film and liquid film Surface Renewal is rapid at filling surface.Acid absorption column 2 top is provided with dehydrating unit 23, is convenient to subsequent treatment process equally.
Above-mentioned filler 11, filler 12 are the filler of same material, and this filler has the advantages that intensity is large, heat-resisting, corrosion-resistant, the pressure drop of gas flowing is low.
During work, the basic purification process of waste gas is as follows: the water absorption tower 1 first leading to two series connection containing trimethylamine waste gas through tail gas absorption house steward 10 that a. trimethylamine stockline 9 produces, three layers of filler 11 are established in every Tai Shui absorption tower 1, spray head 12 is established above every layer of filler 11, spray liquid becomes liquid film at filler 11 surface spreading, through filler in trimethylamine exhaust-gas flow, with liquid film contact mass transfer, waste gas is all flowed to top by bottom in Liang Taishui absorption tower 1.B. the trimethylamine waste gas through water absorption tower 1 is introduced acid absorption column 2 by blower fan 1 again and is processed, three layers of filler 21 are set in every acid absorption column 2, spray head 22 is provided with above every layer of filler 21, spray head 22 sprays dilute sulfuric acid, trimethylamine in spray-absorption waste gas, waste gas is also all flowed to top by bottom in two acid absorption columns 2.C. enter low-temperature plasma equipment 6 through the trimethylamine waste gas that water absorbs and acid absorbs, the trimethylamine molecular link of remnants is interrupted.D. guide the high blast pipe of 25M through purified gas into by blower fan 2 72 and carry out qualified discharge.
