Described fine filter, electric heater, membrane separator, digester, explosion proof control case are integrated on a sledge block.
It is provided with differential manometer on described fine filter.
Bottom described digester, gas outlet is provided with the detection device of dust filter unit and hydrogen sulfide content.
Described digester is two.
Owing to using technique scheme, natural gas enters fine filter, separates liquid water droplets and the solid of more than 5um, in order to guarantee equipment will not occur salt crust to block pipe valve instrument when running.Differential manometer is set on fine filter, needs when pressure reduction is more than 50kpa to change filter element, it is ensured that the separating effect of filter element.The natural gas of removing moisture enters back into electric heater, uses electric heater that natural gas is carried out re-heat intensification, it is ensured that gas temperature is higher than water, hydrocarbon dew point temperature 5～10 DEG C.Natural gas after heating enters membrane separator, and by the centrifugation of organic permeable membrane, the hydrogen sulfide of more than 90% is all saturated to enter and discharges into the torch burning into emptying or focusing on outside infiltration gas.The natural gas of the hydrogen sulfide containing about 100～1000ppm enters digester as the tail gas of membrane separator, by a small amount of hydrogen sulfide in the desulfurizing agent adsorbed gas again of filling in digester, it is ensured that the hydrogen sulfide in natural gas content of output is less than 20ppm.Bottom digester, gas outlet filters out the desulfurizer powder that may carry through dust filter unit, controls desulfurization sledge pressure through Self-operated pressure control valve, and natural gas enters and purifies gas pipe network or local use afterwards.
After desulphurization circulating process completes, explosion proof control case can make the noble gas in nitrogen device become pure micro pressure gas through air compressor decompression and enter digester, through purging, disposes damp in digester, and continue to keep malleation, make to become inside tank harbor.Digester can be caused loss by circulation desulfurization work for a long time, two digesters are set to substitute use at any time, avoid causing the stopping production of system because changing digester, outlet at digester is provided with the detection device of hydrogen sulfide content, so that in real time monitoring is through the natural gas whether conformance with standard of desulfurization, determines simultaneously and substitute the time using two digesters.This system flow simplifies, and can change infield and reuse, reduce cost, ensure the safety of production process simultaneously.
The beneficial effects of the utility model are: facilitate installation and transportation, reusable, low cost, possess monitoring function, the advantage that safety is high.
