Detailed description of the invention
Below in conjunction with Figure of description, the utility model will be further described, but protection domain of the present utility model is not limited in this:
As shown in Figure 1, the ground flare system of methanol-to-olefins matched with devices of the present utility model, comprise torch gas air inlet pipe and closed ground torch 4 and open-type ground flare 7, described torch gas air inlet pipe comprises multichannel torch gas air inlet pipe, separatory, water seal, closed ground torch and open-type ground flare.Torch gas air inlet pipe comprises device regeneration discharge torch gas air inlet pipe; Pressure-regulating valve, safety valve discharge torch gas air inlet pipe and methyl alcohol torch gas air inlet pipe.Regeneration discharge torch gas enters closed ground torch, pressure-regulating valve, safety valve discharge first 3 grades of torch gas enters closed ground torch, latter 20 grades enter open-type ground flare, methyl alcohol torch gas enters open-type ground flare, and the interior regeneration discharge torch gas burner of described closed ground torch and pressure pressure control valve, safety valve discharge torch gas burner interval and arrange.Pressure-regulating valve, safety valve discharge torch gas is by multistage setting.The mode that the utility model combines by adopting closed ground torch and open-type ground flare, for the treatment of the torch gas of methanol-to-olefins device discharge, its security is good, sufficient combustion, environmental pollution are little.
It comprises device regeneration discharge torch gas air inlet pipe; Pressure-regulating valve, safety valve discharge torch gas air inlet pipe and methyl alcohol torch gas air inlet pipe.Regeneration discharge torch gas air inlet pipe pipeline sets gradually point flow container I 1 and water sealed tank I 2, be connected with closed ground torch 4 after separatory and water seal, pressure-regulating valve, safety valve discharge torch gas pipeline sets gradually point flow container II 11 and water sealed tank II 12, be connected respectively with closed ground torch 4 and open-type ground flare 7 by after separatory and water shut off treatment, methyl alcohol torch gas air inlet pipe pipeline sets gradually point flow container III 10 and spark arrester 9, be connected with open-type ground flare 7 again after spark arrester 9 through a point flow container III 10, described pressure-regulating valve, safety valve discharge torch gas inlet manifold arranges pressure transmitter 3, the torch gas burner 6 of methanol emissions gas burner special 8 and 20 grades is set in described open-type ground flare 7, methanol emissions gas burner special 8 is connected with methyl alcohol torch gas air inlet pipe, for combustion methanol torch gas, torch gas burner 6 and pressure-regulating valve, safety valve discharge torch gas air inlet pipe connects, for combustion pressure control valve, safety valve discharge gas, control valve of the present utility model, the torch gas burner 6 of safety valve discharge is provided with 23 grades, wherein 3 grades are placed in closed ground torch, all the other 20 grades are placed in open-type ground flare, the torch gas burner 6 of every one-level arranges control valve 5, the torch gas flow that each control valve 5 sets is different, improve gradually from small to large, each control valve 5 is connected with pressure transmitter 3 signal, different pressure measured by pressure transmitter 3, signal is sent to each control valve 5, the corresponding control valve 5 mated with the pressure limit that control valve 5 sets is opened, torch gas burns from this road torch gas burner 6, when manifold pressure reduces, close successively.1-3 level burner is arranged in closed ground torch, and do not establish Stress control for the 1st grade, be normally open, all the other two-stages arrange Stress control.
The flare system that the utility model combines by adopting closed ground torch 4 and open-type ground flare 7, methyl alcohol torch gas enters open torch 7, and regeneration discharge gas and pressure-regulating valve, safety valve discharge torch gas and be provided separately; Pressure-regulating valve, safety valve discharge torch gas low discharge introduces closed ground torch 4, large discharge introduces open-type ground flare 7, greatly reduce and reduce probability and time that open-type ground flare comes into operation, to reduce public work consumption, reduce fuel gas consumption, steam consumption, solve the environmental problems such as light pollution, realize energy-saving and emission-reduction, environmental friendliness, the low-pressure produced when process units normally runs, low discharge torch gas introduce closed ground torch, to reduce steam consumption; Have a power failure, cut off the water or etc. accident conditions time the large discharge torch gas that produces introduce open-type ground flare, ensure safe combustion.
Because methyl alcohol gas is soluble in water, the water sealed tank of conventional flare system is inapplicable, the utility model arranges spark arrester 9 at this flare line, realize anti-backfire safety measure, and realize without sewage discharge, if be arranged in Enclosed flare system easily because stack effect causes occurring negative pressure in methyl alcohol gas flare stack with other torch gas, there is certain potential safety hazard, according to methyl alcohol gas usually without discharge, once discharge, the feature that then discharge capacity is larger, so be arranged in open flare system by methyl alcohol gas torch gas, device regeneration discharge gas and other pressure-regulating valves, safety valve discharge gas is provided separately, independent pipe laying, combustion head is arranged separately, because adopting nitrogen regeneration in device regeneration technology, a large amount of nitrogen is had in the torch gas of regeneration discharge, if mix with other discharge gas, easily cause fray-out of flame or incomplete combustion, particularly regenerate in liquid phase containing high-carbon component, its burner is different from the burner structure of conventional lower carbon number hydrocarbons, independent burner is set and is conducive to burning completely, and other burner intervals are arranged, be conducive to igniting and auxiliary combustion, the adopted steam auxiliary combustion of closed type torch is conducive to sufficient combustion simultaneously.
Because a small amount of pressure-regulating valve, safety valve discharge gas discharge gas with regeneration and is the torch gas that daily production discharges, be arranged in Enclosed flare system process, the impact of light pollution on periphery can be reduced.
