Embodiment

Below structural principle of the present utility model is explained in detail.

This integrated miniature Nitrogen plant is integrated in absorptive separation column A, B and pretreater C, D and a storage nitrogen jar E in the housing 1, see Fig. 2, with central shaft 16 is that the center is divided into three parts at housing inner-use clapboard 2 with housing 1, and A, B are absorptive separation column, and E is storage nitrogen jar; Respectively be provided with cylindrical shell C, a D at absorptive separation column A, B middle part, cylindrical shell C, D are connected on the base plate 3 of housing 1, and isolate mutually with fractionation by adsorption tower bottom A, B; In two cylindrical shell C, D, aluminium sesquioxide 14 is housed, is used to the pre-treatment that absorbs water, carbonaceous molecular sieve 15 is housed in absorptive separation column A, B, so that oxygen nitrogen separates; The bottom of cylindrical shell C, D is provided with sieve plate 28, and sieve plate 28 separates the unstripped gas uniform distribution that makes into simultaneously with aluminium sesquioxide 14 and air chamber 18.

Unstripped gas is that pressurized air enters air chamber 18 by raw material gas inlet 5, enter equably by sieve plate 28 again and carry out processed in the aluminium sesquioxide 14, the top of cylindrical shell C, D is communicated with absorptive separation column A, B top, sieve plate 13 separates aluminium sesquioxide 14 and carbonaceous molecular sieve 15, the unstripped gas of process dehydration enters and carries out oxygen, nitrogen separation in the carbonaceous molecular sieve 15, and nitrogen is wherein discharged from four egress filtering nets 17 of absorptive separation column A, B bottom.

Absorption and the desorption of absorptive separation column A, B and cylindrical shell C, D hocket, and see following " Nitrogen plant work schedule table " for details; Enter and the output of product gas of unstripped gas are finished by gas path plate 4 and three automatically controlled sluice valves 6, see Fig. 1; The absorption of absorptive separation column A, B and cylindrical shell C, D and the alternation of desorption are also controlled by three automatically controlled sluice valves 6 of this hyperchannel (six passages); The operation of whole Nitrogen plant is handled these three automatically controlled sluice valves 6 by microcomputer controller, and it is switched between three different positionss, according to the work schedule of Nitrogen plant, can finish the technological process of system nitrogen.
