Description
Technical field
The utility model relates to chemical technology field, is specifically related to a kind of semiwater gas desulphurizing system that the work of resistance is used that has.
Background technology
Anhui Quan Sheng Chemical Co., Ltd. strange land resettlement " 24.30 " engineering, in May, 2013, be constructed and put into operation, desulphurization system is taked double-column in series desulfurization process, main, the pre-tower turriform desulfurization pattern the same with internal structure, thionizer is that tower is ￠ 6600 * 41500, by the production and operation of nearly half a year, along with the continuous increase of throughput, (import semi-water gas H2S content is generally at 1500～2500mg/Nm in order to reduce production costs, to mix burning part medium sulphur coal simultaneously
3), install not enough contradiction and progressively expose appearance, run in February, 2014, systemic resistance progressively rises, and starts total system resistance in 5KPa left and right, finally the highest total system resistance increases to 12Kpa, synthetic ammonia output has more than 940 ton of original daily output, drops to 910 tons of left and right of daily output, and various consumption also starts significantly to rise, directly threaten the operation of synthetic ammonia output and whole production system, become and produce a stable difficult point.
In order to do half de-work well, reason is constantly searched in post in the leader of production department and cleaning shop, adjusting process flow process, and through in many ways debugging and search data, finally everybody unanimously thinks due to former inadequate because of thionizer specific liquid rate that half de-systemic resistance increases.After case study is clear, think that the method for falling resistance is mainly to strengthen doctor solution internal circulating load to wash tower, strengthen the dosage of catalyzer simultaneously, but while starting to design due to our company, technological design is the mode that main, pre-tower circulation process separates, main pre-tower each 2 rich solution pumps and two lean pumps, regeneration tank and circulation groove, rich solution groove all separate, can not allocate mutually, so just cannot increase the internal circulating load of king-tower doctor solution, in order to increase the internal circulating load of desulfurization king-tower, need to transform former process pipeline.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of formation simple, and good in economic efficiency have a semiwater gas desulphurizing system that the work of resistance is used.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of have a semiwater gas desulphurizing system that the work of resistance is used, comprise pre-thionizer and main thionizer, described pre-thionizer is connected by pipeline with main thionizer, described main thionizer bottom is connected to king-tower regeneration tank through king-tower rich solution groove and king-tower desulfurization regeneration pump, described king-tower regeneration tank is connected to main thionizer top through king-tower circulation groove and main thionizer lean pump, described pre-thionizer bottom is connected to pre-tower regeneration tank through pre-tower rich solution groove and pre-thionizer regenerative pump, described pre-tower regeneration tank is connected to pre-thionizer top through pre-tower circulation groove and pre-thionizer lean pump, between the pump inlet of described king-tower desulfurization regeneration and pre-thionizer regenerative pump, join the regenerative pump communicating pipe that a diameter is 500mm, at described pre-thionizer lean pump inlet pipe, join and be connected with main thionizer lean pump the lean pump communicating pipe that a diameter is 500m, so just solved the liquid level equilibrium problem that increases internal circulating load and rich or poor liquid bath.
In addition king-tower circulation groove is connected with pre-tower circulation groove, so just king-tower and pre-tower regeneration tank series connection can be used, guarantee the recovery time, be conducive to regeneration and the flotation of sulphur foam, and then increase desulfuration efficiency, simultaneously also solved the problem that rich solution pump is beaten liquid measure deficiency.
The beneficial effects of the utility model are: the utility model method is simple, and equipment investment cost is low, good in economic efficiency, have solved the liquid level equilibrium problem that increases internal circulating load and rich or poor liquid bath, effectively reduce systemic resistance, the production efficiency of guaranteeing.
Accompanying drawing explanation
Fig. 1 is the utility model system diagram.
Embodiment
For technique means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, a kind of have a semiwater gas desulphurizing system that the work of resistance is used, comprise pre-thionizer 1 and main thionizer 2, pre-thionizer 1 is connected by pipeline with main thionizer 2, main thionizer 2 bottoms are connected to king-tower regeneration tank 5 through king-tower rich solution groove 3 and king-tower desulfurization regeneration pump 4, king-tower regeneration tank 5 is connected to main thionizer 2 tops through king-tower circulation groove 6 and main thionizer lean pump 7, pre-thionizer 1 bottom is connected to pre-tower regeneration tank 10 through pre-tower rich solution groove 8 and pre-thionizer regenerative pump 9, pre-tower regeneration tank 10 is connected to pre-thionizer 1 top through pre-tower circulation groove 11 and pre-thionizer lean pump 12, between 4 imports of king-tower desulfurization regeneration pump and pre-thionizer regenerative pump 9, join the regenerative pump communicating pipe 13 that a diameter is 500mm, at pre-thionizer lean pump 12 inlet pipes, join and be connected with main thionizer lean pump 7 the lean pump communicating pipe 14 that a diameter is 500m, so just solved the liquid level equilibrium problem that increases internal circulating load and rich or poor liquid bath.
