Detailed description of the invention
Below implement for illustration of the utility model, but be not used for limiting scope of the present utility model.
The utility model is made up of sulfonation reactor 101, liquid material washing system 102, exhaust treatment system 103, switch valve 1, switch valve 2 105 as shown in Figure 1, when the unlatching of sulfonation process breaker in middle valve 1, switch valve 2 105 are closed, gas phase sulfur trioxide enters sulfonation reactor 101, enter liquid material washing system 102 containing sulfur trioxide tail gas after sulfonation, then enter exhaust treatment system 103; When sulfonation process startup-shutdown state, switch valve 1 cuts out, and switch valve 105 is opened, and gas phase sulfur trioxide directly enters liquid material washing system 102, then enters exhaust treatment system 103.
As shown in Figure 2, tail gas containing sulfur trioxide enters from gas phase sulfur trioxide entrance, through gas line 11 to absorption tower 2, cleaning solution enters continuously from washing liquid material entrance, absorption tower 2 is flowed into through washing liquid material pipeline 10, the numerical value of the given inflow cleaning solution of flowmeter 14, according to the open degree of given Numerical Control control valve 1, circulating pump 9 extracts the cleaning solution in liquid material circulating slot 3, pump into liquid material feed-line 11, enter liquid material pipeloop 5 successively, absorption tower 2, liquid material circulating slot 3, form closed circuit, tail gas containing sulfur trioxide is washed by cleaning solution cyclic absorption in absorption tower 2, liquid material circulating slot 3 top is provided with gas vent 15, discharged by gas vent 15 by the tail gas after absorbing washing, discharged by gas line 2 16 and enter exhaust treatment system.
Along with above-mentioned cyclic absorption washing process constantly carries out, cleaning solution liquid level in liquid material circulating slot 3 constantly raises, when fluid level meter 13 senses that liquid level rises to discharge liquid level, open control valve 28 by controller 12, reach the automatic control to liquid material circulating slot 3 liquid level.In this process, cleaning solution constantly flows into, and discharges immediately after completing absorption process, forms the disposable continuous absorption washing to sulfur trioxide in tail gas.
Manually or electric device closing switch valve 7, sense liquid level scope by fluid level meter 13, open or close control valve 28 by controller 12, the operation that interval discharges cleaning solution can be realized.
In above-mentioned closed circuit, density of setting instrument 17, the saturation degree of washing liquid material is judged according to Density Measuring Instrument 17, when cleaning solution is tending towards saturated, control valve 28 is opened completely, discharge existing washing liquid material in circulating slot, open control valve 1 simultaneously, inject new washing liquid material, said process can also can manually complete automatically.In this process, cleaning solution interval flows into, and cleaning solution recycles, and is detected absorb the degree of depth by Density Measuring Instrument 17, and cleaning solution interval is discharged, and is formed and washs the circulation continuous absorption of sulfur trioxide in tail gas.
Washing liquid material with to be sulfonated material identical, can may also be other and has the unclassified stores absorbing sulfur trioxide function in tail gas, as alkylbenzene, heavy alkyl benzene, petroleum distillate wet goods.Absorption tower is packed tower, also can is stirred vessel, or realizes the device being uniformly mixed function.
Obviously, above-mentioned example of the present utility model is only for the utility model example is clearly described, and is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here cannot give exhaustive to all embodiments.Every belong to the technical solution of the utility model the apparent change of extending out or variation be still in the row of protection domain of the present utility model.
