Abstract
The invention discloses gas separation equipment and provides an adsorption tower for oxygen and nitrogen production. The adsorption tower comprises a support frame and a cylinder body fixed on the support frame, wherein a sealing head is arranged at the lower end of the cylinder body. The adsorption tower is characterized in that a gas inlet distributor is arranged in the sealing head and connected with a gas inlet outside the cylinder body through a U-shaped gas inlet pipeline; the inner top end of the cylinder body is connected with a gas outlet outside the cylinder body through an L-shaped gas outlet pipeline; a sieve plate is arranged inside the connecting position of the cylinder body and the sealing head, and adopts a multilayered structure which is provided with a pore plate, a coir mat, a steel wire mesh and a pressing ring from button to top in sequence. The sieve plate multilayered structure developed by the invention effectively improves the adsorption property, realizes the different gas inlet and outlet effects, ensures the working quality of the adsorption tower and improves the gas purity. In addition, as the gas inlet distributor is developed and arranged at the gas inlet, extraneous gas enters the tower and is more uniformly dispersed on the periphery inside the cylinder body through the gas inlet distributor to perform the adsorption work, so that the working efficiency is effectively improved.
Description
Technical field
The present invention relates to gas separation equipment field, particularly a kind of adsorption tower.
Background technology
Adsorption tower is the equipment realizing adsorption operations.In tower gas-liquid two-phase the type of flow can adverse current also can and flow.Usual employing counter-current operation, adsorbent is filled in tower, contacts with the gas flowed from bottom to top, and the liquid absorbing absorbent is discharged at the bottom of tower, and purified gas is discharged from tower top.
Aluminium oxide and molecular sieve are filled in traditional adsorption tower inside, and under long-term absorption work, aluminium oxide absorbs excess moisture, reduces adsorption effect, must regularly replace adsorbent, brings very large inconvenience to work.At present sought break through be just that how to make absorption tower adsorbs effect better, adsorbent working effect is higher, longer service life, and adsorbent change more convenient.Meanwhile, cost is more cheap, is applicable to more medium-sized and small enterprises clients, improves the market competitiveness.
Summary of the invention
The object of the invention is to solve the problem, provide a kind of oxygen nitrogen adsorption tower, adsorption effect is better, operating efficiency is higher, and convenient and practical, and cost is lower.
Above-mentioned technical problem of the present invention is solved mainly through following technical proposals:
A kind of oxygen nitrogen adsorption tower, comprise support and be fixed on the cylindrical shell on support, described cylindrical shell lower end is provided with end socket, it is characterized in that: in described end socket, establish air inlet distributor, this air inlet distributor is by being " U " font air inlet pipeline connector drum external admission mouth, in described cylindrical shell, top is by gas outlet outer in " L " type outlet pipe connector drum, inside, described Cylinder and end socket junction is provided with sieve plate, described sieve plate is made up of sandwich construction, is orifice plate, palm fibre pad, steel wire, pressure ring from the bottom up successively.
Concrete, described air inlet distributor is made up of cylindrical outer wall and capping, and described outer wall is evenly set side by side with vertical bar shape air dispelling hole, air dispelling hole at least ten two.
Further, described capping external diameter is greater than outer wall outside dimension.
Concrete, in described cylindrical shell, end on the lower side is provided with woven wire cylindrical shell is divided into two parts, and upper part fills molecular sieve, and lower part fills aluminium oxide.
Further, described cylinder top is provided with blind flange, and this blind flange is fixed by asbestos rubber pad, bolt and cylindrical shell.
Further, space is also left in described blind flange and outlet pipe port.
Further, described cylindrical shell urceolus, top position, gas outlet are provided with pressure gauge connection.
The invention has the beneficial effects as follows: this invention exploits a kind of sieve plate sandwich construction, be made up of orifice plate, palm fibre pad, steel wire, pressure ring, effectively improve absorption property, the different-effect realizing air inlet and give vent to anger, further ensure the work quality of adsorption tower, improve gas purity; In addition, develop a kind of air inlet distributor at air inlet place, external gas makes air inlet more be dispersed in cylindrical shell surrounding by air inlet distributor in tower to implement absorption work, effectively increase work efficiency entering; Finally, the present invention be provided with blind flange be assembled into by bolt, asbestos rubber pad and, for convenience detach, easy cleaning and increasing the service life.
