Description
Technical field
The utility model relates to purification for gas field, particularly a kind of purification devices of being prepared high purity acetylene by industrial acetylene.
Background technology
Acetylene is colourless gas, has ether taste, is dissolved in alcohol and ketone, is one of important source material of organic synthesis, can produce acetaldehyde by acetylene, acetic acid, vinylchlorid, the multiple Organic Chemicals such as acetic acid diene.The industrial acetylene gas that adopts calcium carbide and water effect to make, adopts vitriol oil spraying process, sodium-hypochlorite process and chlorine water method to carry out purifying conventionally.For above-mentioned three kinds of purifying process, acetylene gas can with the strong oxidizer such as the vitriol oil, inferior sodium generation oxidizing reaction, acetylene waste is large; Sulfate absorbent heating produces high temperature, and security is not high; In the vitriol oil, clorox and chlorine water method purge process, larger to the usage quantity of purifying agent.And this class acetylene method of purification, does not all relate to the purifying of acetone in steel cylinder outlet acetylene gas.And use technical grade acetylene lower as the yield of the product of the organic synthesis of raw material, make value added lower and can not meet the technical indicator of high purity acetylene far away.
Utility model content
The purpose of this utility model is the shortcoming in order to overcome above-mentioned background technology, improves the added value of industrial acetylene, meets the market requirement of acetylene, and the device that a kind of industrial acetylene purifying is high purity acetylene is provided.
The technical solution of the utility model is: a kind of small-sized high purity acetylene purification devices, it comprises: industrial acetylene cylinder, reducing valve, except acetone adsorption tower, sulphur removal phosphorus catalytic adsorption tower, drying adsorption tower dewaters, grade one filter, secondary filter, surge tank, described industrial acetylene cylinder air outlet connects except acetone adsorption tower inlet mouth, the described acetone adsorption tower air outlet of removing connects sulphur removal phosphorus catalytic adsorption tower inlet mouth, described sulphur removal phosphorus catalytic adsorption tower air outlet connects the drying adsorption tower inlet mouth that dewaters, drying adsorption tower air outlet connection filtering air inlet strainer air outlet connection surge tank inlet mouth dewaters.
Described industrial acetylene cylinder and except being provided with reducing valve between acetone adsorption tower connecting tube.
Described strainer has two, be respectively grade one filter and secondary filter, described grade one filter inlet mouth connects the drying adsorption tower air outlet that dewaters, and grade one filter air outlet connects secondary filter inlet mouth, and secondary filter air outlet connects surge tank.
The beneficial effects of the utility model are: the utility model less investment, volume is little, quality is light, can effectively remove the impurity in industrial acetylene, and the purity acetylene of acquisition reaches more than 99.9%, has met the requirement of present industry for high purity acetylene; Meanwhile, adopt this device, industrial acetylene lower economic worth is obtained to high purity acetylene by purification, improved value-added content of product, created good economic benefit.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Wherein: 1, industrial acetylene cylinder, 2, reducing valve, 3, except acetone adsorption tower, 4, sulphur removal phosphorus catalytic adsorption tower, 5, the drying adsorption tower that dewaters, 6, grade one filter, 7, secondary filter, 8, surge tank.
Embodiment
The present embodiment is a kind of small-sized high purity acetylene purification devices, and it comprises: industrial acetylene cylinder (1), reducing valve (2), except acetone adsorption tower (3), sulphur removal phosphorus catalytic adsorption tower (4), the drying adsorption tower that dewaters (5), grade one filter (6), secondary filter (7), surge tank (8).
As shown in Figure 1, industrial acetylene cylinder (1) passes through reducing valve (2) and is connected except acetone adsorption tower (3), opens the valve of industrial acetylene cylinder (1) or collection dress lattice, and industrial acetylene is entered except acetone adsorption tower (3) with certain pressure; Described acetone adsorption tower (3) air outlet of removing connects sulphur removal phosphorus catalytic adsorption tower (4) inlet mouth, described sulphur removal phosphorus catalytic adsorption tower (4) air outlet connects drying adsorption tower (5) inlet mouth that dewaters, and the drying adsorption tower that dewaters (5) air outlet connects filtering air inlet strainer air outlet and connects surge tank (8) inlet mouth.Described strainer has two, be respectively grade one filter (6) and secondary filter (7), described grade one filter (6) inlet mouth connects drying adsorption tower (5) air outlet that dewaters, grade one filter (6) air outlet connects secondary filter (7) inlet mouth, and secondary filter (7) air outlet connects surge tank (8).
Respectively by except after acetone adsorption tower (3), sulphur removal phosphorus catalytic adsorption tower (4) and the drying adsorption tower that dewaters (5), remove the acetone gas, hydrogen sulfide, phosphuret-(t)ed hydrogen and the aqueous vapor that in technical grade acetylene, contain through technical grade acetylene.Wherein except acetone adopts column cocoanut active charcoal; Sulphur removal phosphorus adopts ature of coal Powdered Activated Carbon; The dry 3A of employing molecular sieve dewaters.In acetylene gas after three catalytic adsorption towers, foreign matter content is lower than 500ppm.Remove solid particulate through grade one filter (6) and secondary filter (7), because the dried high purity acetylene of adsorption catalysis is taken trace molecule sieve powder out of.Wherein the filtering accuracy of grade one filter (6) is 0.1 micron, and the filtering accuracy of secondary filter (7) is 0.01 micron.Enter surge tank (8) through the high purity acetylene of processing preparation, prepare to use.
Can make the purity of industrial acetylene be promoted to more than 99.9% by this device, meet the technical indicator of high purity acetylene, create higher economic benefit.Take 1kg acetylene as example, 1kg industry acetylene price is 25 yuan, and the price of 1kg high purity acetylene is 150 yuan, and to produce 200 tons of acetylene per year as example, creation economic benefit necessarily, and input cost every year only has tens0000, and easy and simple to handle.
