Abstract
The utility model relates to methane purifying device, and methane purifying device is connected with gas holder by water seal arrangement, and methane purifying device comprises liquid collecting cavity, filtering chamber, gas-liquid separation chamber; One end of filtering chamber is provided with gas inlet, and the other end is connected with gas-liquid separation chamber; Gas-liquid separation chamber is provided with pneumatic outlet; Liquid collecting cavity is communicated with gas-liquid separation chamber with filtering chamber respectively, is provided with liquid discharge outlet and fluid level controller, and is positioned at the bottom of filtering chamber and gas-liquid separation chamber; In filtering chamber, be provided with glass fibre filtering element; Gas-liquid separation chamber is provided with gas liquid separation element.Set up after biogas filter separator, in gas, moisture content, impurity can significantly reduce, thereby save spare parts and machine material consumption cost, and desulphurization system process operation is stable, and production efficiency significantly promotes; This plant investment working cost is low, installs and uses easy.
Description
Technical field
The utility model relates to methane purifying device, and special design can be removed solid impurity in biogas and the refining plant of liquid impurities.
Background technology
My company is used unstripped gas from connection marine life scientific & technical corporation, produces biogas through high temperature anaerobic, contains methane, carbonic acid gas, hydrogen sulfide composition in marsh gas raw materials gas, wherein in unstripped gas, also carries impurity, moisture and some microorganisms secretly.
Existing technique does not arrange filter plant at fan outlet, in gas, impurity has direct harm to rear processing apparatus operation: 1, impurity can cause visual plant to accelerate corrosion after entering biogas blower fan, Marsh gas compression machine and decarbonization system, cause evaporating, emitting, dripping or leaking of liquid or gas, impact is normally produced; 2, impurity and microorganism are brought desulphurization system into, can cause in doctor solution microorganism poisoning, reduce desulfuration efficiency, increase supplementary product onsumption; The water that in gas, moisture and gas produce due to temp-difference condensing, all enter compressor with air-flow, especially winter, gas band liquid was even more serious, medium belt liquid can cause cylinder coking, the damage of accelerating the parts such as piston ring, air valve was lost efficacy, greatly shorten the unit operation cycle, in addition because liquid is incompressible, the operating safety of serious threat compressor unit.Fan outlet need increase upper filtration unit, and after ensureing, procedure technology equipment is stable.
Summary of the invention
A biogas filtering and purifying on methane purifying device of the present utility model increases before methane air blower entrance house steward.Purification efficiency is high, and dust containing capacity is large, operates steadily, and investment working cost is low, installs and uses easy.
A kind of methane purifying device, described methane purifying device is connected with gas holder by water seal arrangement, and described methane purifying device comprises liquid collecting cavity, filtering chamber, gas-liquid separation chamber; One end of described filtering chamber is provided with gas inlet, and the other end is connected with gas-liquid separation chamber; Described gas-liquid separation chamber is provided with pneumatic outlet; Described liquid collecting cavity is communicated with gas-liquid separation chamber with filtering chamber respectively, is provided with liquid discharge outlet and fluid level controller, and liquid collecting cavity is positioned at the bottom of filtering chamber and gas-liquid separation chamber; In described filtering chamber, be provided with glass fibre filtering element; Described gas-liquid separation chamber is provided with gas liquid separation element.
First biogas enter gas filtration chamber, and glass fibre filter core is housed in filtering chamber, and solid particulate is held back by glass fibre filtering element, and liquid mist is owing to condensing in the surface of glass fibre, and liquid particle is internal surface coalescent the growing up gradually of glass fibre.Can enter filter core inner flow passage and then enter liquid collecting cavity because the shock action of air-flow comes off out from internal surface when drop arrives when certain size; Fog in gas separates by gas liquid separation element, and it can effectively trap drop, to prevent exporting being carried secretly of drop, further improves separating effect.After liquid return after separation, enter liquid collecting cavity, flow out by fluid level controller and discharge outlet.Last clean gas outflow filter separator.Along with the increase of combustion gas throughput, be deposited on particle on filter core and can cause the increase of gas filter pressure reduction, in the time that rising to prescribed value, (reads from differential manometer) pressure reduction, illustrate that filter core is seriously stopped up, should change in time.
Gas is less by pressure reduction after strainer, makes the system can smooth running, and after ensureing, Desulfurization System pressure surge is less.In increasing after biogas filter separator, in gas, moisture content, impurity can significantly reduce, visual plant in production system is as methane air blower, the prolongation of Marsh gas compression machine consumable accessory replacement cycle, evaporating, emitting, dripping or leaking of liquid or gas reduces, increase running period, thereby save spare parts and machine material consumption cost, desulphurization system process operation is stable, and production efficiency significantly promotes; Investment working cost is low, installs and uses easy.

Embodiment
A kind of methane purifying device, described methane purifying device is connected with gas holder by water seal arrangement, and described methane purifying device comprises liquid collecting cavity, filtering chamber, gas-liquid separation chamber; One end of described filtering chamber is provided with gas inlet, and the other end is connected with gas-liquid separation chamber; Described gas-liquid separation chamber is provided with pneumatic outlet; Described liquid collecting cavity is communicated with gas-liquid separation chamber with filtering chamber respectively, is provided with liquid discharge outlet and fluid level controller, and is positioned at the bottom of filtering chamber and gas-liquid separation chamber; In described filtering chamber, be provided with glass fibre filtering element; Described gas-liquid separation chamber is provided with gas liquid separation element.
First biogas enter gas filtration chamber, and glass fibre is housed in filtering chamber, and solid particulate is held back by glass fibre filtering element, and liquid mist is owing to condensing in the surface of glass fibre, and liquid particle is internal surface coalescent the growing up gradually of glass fibre.Can enter filter core inner flow passage and then enter liquid collecting cavity because the shock action of air-flow comes off out from internal surface when drop arrives when certain size; Fog in gas separates by gas liquid separation element, and it can effectively trap drop, to prevent exporting being carried secretly of drop, further improves separating effect.After liquid return after separation, enter liquid collecting cavity, flow out by fluid level controller and discharge outlet.Last clean gas outflow filter separator.Along with the increase of combustion gas throughput, be deposited on particle on filter core and can cause the increase of gas filter pressure reduction, in the time that rising to prescribed value, (reads from differential manometer) pressure reduction, illustrate that filter core is seriously stopped up, should change in time.
Gas is less by pressure reduction after strainer, makes the system can smooth running, and after ensureing, Desulfurization System pressure surge is less.In increasing after biogas filter separator, in gas, moisture content, impurity can significantly reduce, visual plant in production system is as methane air blower, the prolongation of Marsh gas compression machine consumable accessory replacement cycle, evaporating, emitting, dripping or leaking of liquid or gas reduces, increase running period, thereby save spare parts and machine material consumption cost, desulphurization system process operation is stable, and production efficiency significantly promotes; Investment working cost is low, installs and uses easy.
