Abstract
The utility model relates to a separated absorption tank, which is an improvement of the structure of the adsorption tank in PSA nitrogen-making equipment. The utility model is characterized in that the separated absorption tank comprises an upper sealing head, a tank body, and a lower sealing head; the supper sealing head, the tank body, and the lower sealing head are connected by a flange disk; a double-layer flow distribution plate is put on the bottleneck of the upper sealing head and the lower sealing head respectively; the connecting position of the lower sealing head and the tank body is provided with a doubly layer flow distribution plate to implement three-stage flow distribution too. In the PSA nitrogen-making equipment, the purity of nitrogen gas can be improved from 97.5% to more than 99.5%, and flow quantity per hour can be 5 nm< 3 > to 200 nm< 3 > after the adoption of the utility model.
Description
The utility model relates to the improvement of the adsorption tanks structure in the PSA equipment of making nitrogen.
Form by air cleaning system, piece-rate system, control system and nitrogen purification system in the current PSA equipment of making nitrogen, piece-rate system comprises adsorption tanks and nitrogen storage tank, wherein adsorption tanks are cores of piece-rate system, and it is directly connected to the purity and the flow of product-nitrogen.
Existing adsorption tanks are overall structure or the diad structure be made up of upper cover and tank body mostly.The adsorption tanks ratio of height to diameter is 6:1～4:1.Only be provided with one-level shunting in the tank body, use a flow distribution plate, the ventilative area that is provided with on its flow distribution plate is little, makes that the adsorption tanks desorption pressures is low, outlet pressure is little, and adsorption time is lacked, and causes that the nitrogen gas purity produced is low, flow is little.
The purpose of this utility model provides a kind of split type adsorption tanks, and it has rational ratio of height to diameter, in establish the shunting of three grades of flow distribution plates, improve the purity and the flow of nitrogen.
The utility model is to realize like this.Original adsorption tanks are divided into upper cover, tank body and low head, and upper and lower end socket adopts ring flange to be connected with tank body.Respectively place the pair of lamina flow distribution plate at upper cover bottleneck and low head bottleneck, also place a double-deck flow distribution plate, constitute three grades of flow distribution plate shuntings at low head and tank body commissure place.
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 the utility model structural representation.
The double-deck flow distribution plate structural representation of Fig. 2.
The double-deck flow distribution plate A-A of Fig. 3 cut-away view.
Referring to Fig. 1, a kind of split type adsorption tanks, comprise tank body, supporting leg (14), end socket, base (15), air inlet pipe (16), escape pipe (17), end socket extension tube attached (18), flow distribution plate and ring flange, it is characterized in that adsorption tanks are made up of upper cover (1), tank body (2) and low head (3), upper and lower end socket adopts ring flange (4) to be connected with tank body, respectively place a double-deck flow distribution plate (8) at upper cover bottleneck (5) and low head bottleneck (6), also lay a double-deck flow distribution plate at low head and tank body commissure place.
Referring to Fig. 2, Fig. 3, the used flow distribution plate of the utility model is double-deck flow distribution plate, and double-deck flow distribution plate is to accompany two layer of 80 order～100 purpose stainless steel cloth (9) by two flow distribution plates (7) centre, and periphery is sealed with spill adhesive tape (10).
Flow distribution plate (7) is a circular slab, and diameter is identical with the tank body internal diameter, and it is 5 millimeters centre bore (11) that flow distribution plate is provided with the aperture, is benchmark with the centre bore, extends laterally and beats air-vent (12), and the aperture is strengthened gradually, is uniformly distributed in the flow distribution plate face.
Find in the practice, when the air-vent area accounts for the flow distribution plate gross area 70% best results when above.Therefore the flow distribution plate face is divided into three ventilating areas, first ventilating area is 1/3rd places that the flow distribution plate radius size is arrived at the center with the centre bore, its air-vent area accounts for 5% of the flow distribution plate gross area, second ventilating area extends out to 2/3rds places of radius size with first ventilating area, 20%, the 3rd ventilating area that its air-vent area accounts for the flow distribution plate gross area extends to the flow distribution plate cylindrical laterally with second ventilating area, and its air-vent area accounts for 45%～47% of the flow distribution plate gross area.
The ratio of height to diameter of adsorption tanks is 2.5:1.
When producing nitrogen, fill molecular sieve in tank body, do not interspace for making between the molecular sieve, the utility model is provided with a spring (13) on be placed on the double-deck flow distribution plate of upper cover, and its internal diameter is slightly larger than upper cover extension tube attached diameter, is used to compress molecular sieve.
In the present embodiment, it is 6 millimeters and 3 millimeters steel plates making that flow distribution plate adopts thickness, adopts 100 order stainless steel cloths.
In the PSA equipment of making nitrogen, use adsorption tanks provided by the utility model after, nitrogen gas purity can reach more than 99.5%, per hour flow is at 5NM
3～200NM
