Abstract

The invention can be used in the instrumental process of cleaning gas mixtures by the method of adsorption in the stationary layer in the chemical, metallurgical and other branches of the national economy. The purpose of the invention is to increase the efficiency of the regeneration process by passing the regenerating gas sequentially through the sorbing elements. The adsorber is provided with vertical partitions installed along the axis of the sorbing elements, parallel to the wall of the housing in which the regenerating eye supply nozzle is located. Partitions divide the working space into a series of sections through which the regenerating gas 2 sludge passes successively.

Description

The invention relates to instrumentation of the gas cleaning process by adsorption and can be used in the chemical, metallurgical and other sectors of the national economy.

The purpose of the invention is to increase the efficiency of the regeneration process by passing the regenerating gas sequentially through the sorbing elements.

Fig 1 shows the adsorber in the desorption stage, general view; Fig 2 - section a a in fig 1.

The adsorber includes a housing 1. chamber 2 with tubular carbon sorbing elements 3 G of circular cross section (Fig. 2), collecting 7 and distributing 8 collectors, inlet 9 for the gas to be cleaned, outlet for 10 purified gas, inlet 11 for the dehydrating agent outlet pztrubgi 12 for waste drgorbier agent with desorbate. valves 13-19 for switching process flows pneumatic actuators 20-24 partitions 25 and 26. connected to the sorbing elements 3 4 and 5. 6, respectively, and the walls of the housing and separating the chamber 2 into sections 27-29, interconnected through the filtering walls of the sorbing elements 3, 4 and 5, 6, the holes 30-32 for entry into the chamber 2 of the gas to be purified from the distribution manifold 8

The tubular sorbing elements 3–6 from one end are plugged and may have a round, oval, square polygon or star-shaped cross section and may be made of activated carbon fiber material of the corresponding shape on the frame.

regenerating agent at the stage of regeneration.

The device works as follows

Into the adsorber, gas purification and sorbent regeneration stages are alternately carried out.

At the purification stage, the gas to be cleaned through the inlet 9 enters the dispensing manifold 8, then through the openings 30- 32 is supplied to sections 27-29 of chamber 2, is filtered through the walls of the sorbing elements 3-6 and is cleaned by adsorption cleaned gas, carbon adsorbent. The purified gas exits through the open ends of the sorbing elements into the sorbing collector 7 and then is discharged through the outlet 10 to the atmosphere. At the cleaning stage, valves 15, 26, 17, 18, 19 are open, while 13 and 14 are closed.

At the stage of sorbent regeneration, valves 15-19 are closed (using pneumatic actuators 20-24, respectively), and valves 13 and 14 are opened. The desorbing agent (for example, water vapor) through the inlet 11 enters section 27, passes through the filter walls of the sorbent elements 3 and 4, enters section 28, passes through the filter walls of the sorbent elements 5 and 6. enters section 29 and then the outlet 12 is removed from the adsorbent together with the desorbed products.

Thus, at the stage of sorbent regeneration, the desorbing agent successively passes through several filtering walls of the sorbing elements. This allows a more efficient use of the desorbing agent due to the more complete utilization of its heat and pressure.

ability to reduce its specific consumption by 1.5-3.5 times (depending on the thickness of the filtering wall of the sorbent element and the characteristics of the sorbent material, the composition of the gas to be purified, the type

desorption agent and the required degree of desorption).
