At first see also Fig. 1, the utility model is by an air inlet switch (1), five cartridge filters (2) (3) (4) (5) (6), the molecular sieve of two parallel connections (71) (72), one vapour liquid separator (8) and a storage tanks (9) combine, wherein air inlet switch (1) is connected respectively in the inner body (21) (31) of the first two cartridge filter (2) (3) with pipeline (11) (12), the bottom of pipeline (21) (31) connects the transverse tube (23) (33) of establishing a tool hole (22) (32), two pipelines (11) (12) are provided with again with the passage of valve body (13) (14) with the decision gas communication, the inner barrel of two cartridge filters (2) (3) all ccontaining with an amount of potassium permanganate with as the filter material desulfurization, two cartridge filters (2) (3) cylindrical shell upside is communicated with the body that is connected to the 3rd cartridge filter (4) central authorities with the pipeline (24) (34) that communicates, body (41) bottom is for having the transverse tube (43) of hole (42), and fill an amount of water at cartridge filter (4) and wash, be communicated in molecular sieve (71) (72) dehumidifying in parallel in cartridge filter (4) upper end with a pipeline (44) simultaneously, pipeline (44) is communicated with molecular sieve (71) (72) with valve body (45) (46) respectively, pipeline with the decision gas communication, and molecular sieve (71) (72) downside is connected in pipeline (75) with valve body (73) (74) respectively, while valve body (45) (73), (46) (74) are relative opening, close action, make the pipeline that forms a circulation, pipeline (75) is connected in cartridge filter (5) again, be provided with two mutual stacked cylindrical shells (51) (52) in the cartridge filter (5), two cylindrical shells (51) (52) inside fills with the activated carbon filter material and removes look with deodorization, and be drilled with hole (511) in the bottom of two cylindrical shells (51) (52)) (521), and set firmly a filter screen (53) being positioned at the cylindrical shell of downside (52) bottom side, still have a suitably big or small space (54) simultaneously in filter screen (53) below, and connect in the downside of cartridge filter (6) with a valve body (55) by this space (54).The body (62) that this cartridge filter (6) has hole (61) by the bottom side with a tube wall extends into the inside of cylindrical shell, body (62) periphery overlaps and covers an outer tube (63), the periphery of outer tube (63) is provided with body (62) and goes up the relative hole (64) of hole (61), and at the filter cloth (65) of outer tube (63) periphery winding with suitable thickness, and be connected to vapor-liquid separation chamber (8) with a pipeline (66) again in cartridge filter (6) bottom side part at body (62), this vapor-liquid separation chamber (8) inner barrel two lateral circle surfaces interlace with the interval with the interleaved mode setting and are to projecting inward resistance body (81), on the two side faces, adjacent resistance body (81) medial extremity is overlapped shape down, form a circuitous passage in the vapour liquid separator (8) between each resistance body (81) and make, and be provided with a net lamellated mist eliminator (85) in the upper end, vapour liquid separator (8) one side upper ends also are connected to a storage tanks (9) with a valve body (82), a pressure relief valve (83) is established on the top, and downside is then established a water shoot (84).

Referring to Fig. 2, can be by the carbonic acid gas system that air inlet switch (1) is introduced via the upward keying of the valve body (13) (14) of setting of pipeline (11) (12), and decide in the middle that trough of the filter vat (2) (3) that enters dress potassium permanganate solution in two, this mainly is to allow two cartridge filters (2) (3) be separated by replaced use in one day, cause built-in potassium permanganate solution filtering function to reduce to avoid long-term the use continuously, potassium permanganate solution is a kind of brown oxygenant, can remove H ₂S, SO ₂Metallic impurity, metal-powder and carbon granules, in diagram, valve body (14) is closed, and make carbonic acid gas enter body (21) by pipeline (11), and disengage and enter in the cartridge filter (2) from the hole (22) of its bottom transverse tube (23), carbonic acid gas is to rising in the bubble mode in the potassium permanganate filtered liquid within it, make and in uphill process, carry out initial filter action, disengage through body (41) hole (42) of transverse tube (43) bottom it from the pipeline (24) (34) that is communicated with then and enter in the cartridge filter (4), and in it the cleaning of water, and use whether still carry potassium permanganate solution in the identification carbon dioxide, the water of filling needs replacing every day to keep clean in the cartridge filter (4), then carbon dioxide is again from inside that the body (44) of cartridge filter (4) top one of enters two molecular sieves (71) (72), this that valve body opening of looking in two valve bodies (45) (46) decides, in figure, be example with valve body (45) opening, then pipeline (75) valve body (73) upward is open synchronously, carbon dioxide is entering within the molecular sieve (71), can isolate 20% moisture, and allow the water content of carbon dioxide reduce, utilize two molecular sieves (71) (72) to be used alternatingly, with coil heats use more than 105 ℃ nitrogen regeneration with the moisture band of molecular sieve from, improve the function of isolating moisture, and when avoiding single the use whole device with stopping, then, again by valve body (73) by the road (75) enter next cartridge filter (5), and through after the filtration of filter cylinder (51) interior activated carbon and the hole (511) by the bottom side, enter then in the cylindrical shell (52) and filter via activated carbon filter material in it again, and enter the space (54) of cartridge filter (5) below after by filter screen (53) by the hole (521) of bottom side, this cartridge filter (5) is mutually stacked with two cylindrical shells (51) (52) in it, then can extract out easily to do the replacing of activated carbon filter material in use for some time, simultaneously, set firmly the closeer filter screen of a mesh (53) in the below of lower position cylindrical shell (52), so can effectively block activated carbon and fall into the space of its downside (54), and then enter the inside of cartridge filter (6) from valve body (55), and be under the gaseous phase at carbonic acid gas, it just can see through the filtration of filter cloth (65), and enter the inside of body (62) along relative hole (61) via the hole (64) of outer tube (63), utilize setting up of filter cloth (65), can filter still undissolved metallic impurity powder, make carbon dioxide more pure, change in the vapour liquid separator (8) via pipeline (66) then, enter gasiform carbonic acid gas in the vapour liquid separator (8), because two side faces is provided with the resistance body (81) of cross-like at interval in the tube, and make the course of carbonic acid gas become circuitous bent passage, then will collide the bottom side of each resistance body (81) in the current process of carbonic acid gas, the mist eliminator (85) that cooperation is provided with the top, and make the moisture that under it is in contact with one another, both can make carbon dioxide include condense into water droplet at resistance body (81) downside surface, the agglomerative water droplet can be discharged through the water shoot (84) of cylindrical shell below after dropping, if hypertonia then can be disengaged by pressure relief valve (83) appropriateness of cylindrical shell upside during the course simultaneously, to prevent the generation of unscheduled event.This device can make the filter of carbonic acid gas through bed filtration tube (2) (3) (4) (5) (6), therefore can guarantee to filter out the H in the carbonic acid gas ₂S, SO ₂And carbon granules, and remove the taste of carbonic acid gas, and the lifting quality, purified again can edible interpolation carbonic acid gas, carry in storage tanks (9) via valve body (82) again to store in order to use, in addition, this device also can be installed in vapour liquid separator (8) two molecular sieves (71) (72) side before, and cartridge filter (6) is switched to storage tanks (9) with pipeline (66), and this change can alleviate the operation of molecular sieve (5), and reaches same function.
