Abstract
The utility model discloses a portable gas purifying device, belonging to a portable purifying device for purifying a methane gas by using a gas diffusion process. The portable gas purifying device comprises an active carbon filter, a dewatering purifier, a first desulfurizer, a gas compressor, a deoiling purifier, a second dewatering purifier, a buffer tank, a dewatering purifier group and a second desulfurizer which are sequentially connected, wherein the second desulfurizer is connected with a membrane type gas separator. According to the portable gas purifying device, through a series of treatment equipment, impurities mixed in methane or natural gas are separated from methane or natural gas; by adopting the membrane type gas separator, methane and carbon dioxide are separated under a normal temperature state, so that the content of purified methane reaches 97-100 percent, and purified methane can be directly used as an efficient fuel of an engine.
Description
Technical field
The utility model relates to a kind of portable purifying plant that utilizes gaseous diffusion process purification methane gas.
background technology
Biogas is mainly by gas compositions such as 50%～70% methane and 30%～50% carbonic acid gas during without purification processes, and calorific value is generally at 20.16MJ/m
3～28.98MJ/m
3between, energy density is low, can only use as domestic energy for a long time.The calorific value of highly purified methane (97%～100%) is 38.22MJ/m
3, can be used as oil substitutes directly as motor spirit.If can obtain high purity methane from common biogas and refuse embedded gas, can widen the Application Areas of China's renewable energy source biogas, solve the realistic problems such as vehicle fuel shortage.
Methane purification has four kinds of methods to realize at present, is respectively absorption process, pressure swing adsorption process, condensation at low temperature and membrane separating method.Absorption refining method is to utilize the physical chemistry absorption characteristic of By Amine Solutions and carbonic acid gas to realize.Pressure Swing Adsorption method is to utilize the selective adsorption feature of sorbent material (as molecular sieve etc.) to carbonic acid gas, on sorbent material, relative other gaseous components of carbonic acid gas have higher separation factor, reach the object that carbon dioxide in methane is removed.Cryogenic condensation method of purification is the feature of utilizing co 2 liquefaction temperature high, by cold service, the carbonic acid gas in biogas is liquefied, and methane component is discharged with refined product gas as non-condensable gas.Membrane sepn method of purification is to utilize gas with various component by the difference of membrane permeability effect, to realize under pressure-driven, the seepage velocity of normal conditions carbon dioxide is fast, as fast gas, to see through gas, discharge, the seepage velocity of methane is slow, as slow gas, with saturating residual air form, obtains refined product gas.In industrial production, in order to improve the concentration of methane gas, often adopt Using Multistage Membranes separating technology.
Membrane separation process, because the reasons such as technology maturity and economy are applied also seldom, particularly, on small-sized methane purification equipment, does not adopt membrane separation plant substantially.
Utility model content
The purpose of this utility model is to provide a kind of portable gas purifying plant, is convenient to transportation, can carry out the purification processes of gas whenever and wherever possible.
For achieving the above object, the technical solution of the utility model is: portable gas purifying plant, comprise the activated charcoal filter, dewatered clean device, the first devulcanizer, gas compressor, de-oiling cleaner, the second dewatered clean device, surge tank, dewatered clean device group, the second devulcanizer that connect successively, described the second devulcanizer connects membrane type gas separator.
While adopting technique scheme, the utility model is by a series for the treatment of facility, by the impurity mixing in biogas or Sweet natural gas and gas delivery, simultaneously, adopted membrane type gas separator, under normal temperature state, get final product separation of methane and carbonic acid gas, make the methane content after purifying reach 97%～100%, can directly be used as the highly effective fuel of engine.
Further, the exit end of described membrane type gas separator has connected gas compressing apparatus.By gas compressing apparatus is set, can directly the gas after purifying be carried out to compressing and canning, realize storage timely, be convenient to transportation and use.
Further, the exit end of described the second devulcanizer has also connected reliever, and described reliever has connected gas engine, described gas engine-driven gas compressor and gas compressing apparatus.The marsh gas raw materials of preliminary treatment is used for to gas engine, then drives gas compressor and the gas compressing apparatus in equipment for purifying by gas engine, can gather materials on the spot, in the place that lacks fuel oil and electric power supply, also can use at any time this equipment.
Further, for convenient transportation, body is arranged on the base plate with movable pulley.Above-mentioned design, can transport device by mode vehicle-mounted or traction, reach the object of portable transportation.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the structural representation of the utility model portable gas purifying plant embodiment.
Embodiment
As shown in Figure 1, the utility model portable gas purifying plant, passes into mixed gas, first passes through strainer, and gac is housed in strainer, and the solid impurity in gas is carried out to Adsorption.Enter afterwards cleaner A, cleaner A is used for deviating from the moisture content of gas.Enter afterwards thionizer A, for deviating from mixed sulfurous gas, as H
2s.Gas carries out supercharging by compressor A afterwards, enters cleaner B and deviate from the lubricating oil of gas through being mingled with after compressor A after supercharging.Enter afterwards cleaner C, again dewater.Gas after dewatering enters in surge tank, and surge tank is for stored-gas, and in maintenance purifying plant, air pressure is stable.From surge tank, gas out enters cleaner group, for again deviating from moisture content.Enter again afterwards digester B, again deviate from sulfurous gas wherein.Finally enter membrane separation apparatus, the seepage velocity of fast air carbon dioxide is fast, to see through gas, discharges or carries out collection and treatment, and methane obtains refined product gas as slow gas with saturating residual air form.
Afterwards, the methane of purifying through membrane separation apparatus can collect by pressure reducer A and compressor B, for example can compressing and canning, conveniently transportation and use.Moreover, at thionizer B place, increase a pneumatic outlet, gas is through entering pressure reducer B after thionizer B, be used as again the fuel of gas engine A and gas engine B, wherein, gas engine A is for drive compression machine A, and gas engine B is for drive compression machine B, can there is no, under the prerequisite of exterior power input, only to rely on the methane gas of rough purification to turn round as fuel feed whole system.
Above-described is only preferred implementation of the present utility model, should be understood that, for a person skilled in the art, not departing under prerequisite of the present utility model, can also make some distortion and improvement, for example, whole purifying plant can be arranged on the base plate with movable pulley, utilize vehicle traction or be directly installed on automobile, can conveniently transport, being transported to source of the gas whenever and wherever possible and carrying out purification.In addition, whole purifying plant can be arranged in the space of 8 cubic metres within, convenient transportation and transhipment, these also should be considered as protection domain of the present utility model.
