Abstract
The utility model discloses a low-temperature absorber which comprises a cylinder, a refrigerant jacket, a refrigerant pipeline, fins, a refrigerant inlet, a refrigerant outlet, a gas inlet, a gas outlet, a molecular sieve inlet and a molecular sieve outlet; the refrigerant jacket is welded outside the cylinder; six fins are uniformly welded on a refrigerant channel in the center of the cylinder along a circumferential direction; the refrigerant inlet is arranged above the cylinder; the refrigerant channel is connected with the refrigerant jacket 4 in 210 degrees, and is fixed in the cylinder; the refrigerant outlet is welded with the refrigerant jacket in 90 degrees on the upper section of the refrigerant jacket; the molecular sieve inlet is welded right above the cylinder; the molecular sieve outlet is welded right below the cylinder; the gas inlet is welded 15mm outside the molecular sieve outlet; and the gas outlet is welded 15mm outside the molecular sieve inlet. Consequently, the absorber is formed. Due to the low-temperature absorber, a low-temperature method and an absorption method are well integrated, so that the problem that the mass transfer and heat transfer efficiency of the absorber is low is effectively solved, a cold source is repeatedly used, and the energy consumption is greatly reduced.
Description
Technical field
The utility model belongs to the adsorber technology field, relates to a kind of gas separation, the low-temperature adsorber that is used for gas separation that particularly a kind of absorption method and low temperature process combine.
Background technology
In gas industry, need often to use absorber carry out gas and separate and purify, and cryogenics, be still the main means of extensive divided gas flow so far, have the large-scale production advantage that can not be substituted.Low-temperature adsorption is that absorption method and low temperature process combine, and major advantage is a purifying degree of depth height, can be applicable to the large-scale production hyperpure gas with impurity removal to 10-6～10-8 order of magnitude usually.Purify in air separation, rare gas is purified, and natural gas separates purifies, the special gas preparation, and fields such as various tail gas separation are widely used.The low-temperature adsorption that adopts generally carries out precooling with condenser to gas before absorber at present, perhaps cools off in the absorber outside, and its shortcoming is except wasting a large amount of low-temperature receivers, and it is also very low that mass transfer changes thermal effect.
The utility model content
The purpose of this utility model is to solve a large amount of low-temperature receivers of waste, the inefficient problem of mass-and heat-transfer in the above-mentioned prior art, and the heavy duty detergent low-temperature adsorber of a kind of mass-and heat-transfer efficient height, recycling low-temperature receiver is provided.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of low-temperature adsorber comprises cylindrical shell 5, refrigerant chuck 4, refrigerant pipe 7, fin 6, refrigerant import 10, refrigerant exit 3, gas feed 9, gas vent 2, molecular sieve import 1 and molecular sieve outlet 8;
Place the refrigerant passage 7 at cylindrical shell 5 centers along the circumferential direction evenly to weld six roots of sensation fin 6;
Refrigerant import 10 is welded with cylindrical shell with 120 ° above cylindrical shell 5, welds with refrigerant passage 7 upper ends again; 7 of refrigerant passages are connected with refrigerant chuck 4 with 210 °, and refrigerant passage 7 is fixed in the cylindrical shell 5;
Refrigerant exit 3 welds with refrigerant chuck 4 with 90 ° at refrigerant chuck 4 epimeres;
Molecular sieve import 1 welding place cylindrical shell directly over;
Gas feed 9 is welded in molecular sieve outlet 8 outer 15mm places;
Gas vent 2 is welded in molecular sieve import 1 outer 15mm place.
Constitute a kind of heavy duty detergent low-temperature adsorber with this.
The beneficial effects of the utility model are: the utility model provides a kind of heavy duty detergent low-temperature adsorber, and low temperature process and absorption method are combined well, and it is low to solve absorber mass-and heat-transfer efficient effectively, and the recycling low-temperature receiver, greatly reduces energy consumption.
Description of drawings
Fig. 1 is a structural representation of the present utility model, wherein:
1 molecular sieve import, 2 gas vents, 3 refrigerant exits, 4 refrigerant chucks, 5 cylindrical shells, 6 fins, 7 refrigerant pipes, the outlet of 8 molecular sieves, 9 gas feeds, 10 refrigerant imports, 11 adsorbents.
The specific embodiment
Gas enters cylindrical shell 5 through gas feed 9, carries out the gas exchange with adsorbent 11 in the cylindrical shell 5, airflow direction from lower to upper, through cryogenic absorption, impurity is adsorbed on adsorbent 11, the gas behind the purifying is discharged from gas vent 2; Refrigerant enters refrigerant passage 7 from refrigerant import 10, discharges through refrigerant exit 3, provides low-temperature receiver with this, and refrigerant flows from top to bottom, and enters into the refrigerant chuck along refrigerant pipe, realizes lowering the temperature simultaneously inside and outside the high-pressure seamless cylindrical shell.
