SU1366187A1 - Adsorber - Google Patents

Description

The invention relates to the instrumentation of the processes used for the recovery of practically water-immiscible organic solvents, in particular trichlorethylene, by the method of adsorption and reduces the intensity and height of the apparatus, as well as improve serviceability. The adsorber consists of a box-type housing 1, divided into sections 2 by vertical partitions 3, fastened to the upper 4 and lower 5 bases of the housing with a window 6 for the passage of gas.

In the lower part of the body are located the lattices 7, on which the adsorbent is poured. 1 hp f-ly. 3 il.

The invention relates to the instrumentation of the processes used for the recovery of practically water-immiscible organic solvents, in particular trichlorethylene, by the method of adsorption in the production of degreasing parts in the chemical, engineering, electronic and other industries.

The purpose of the invention is to reduce the metal and height, ease of maintenance, as well as the full use and the possibility of desorption with water vapor.

FIG. 1 shows the expanded scheme of the adsorber; in fig. 2 - adsorber, longitudinal section; in fig. 3 - the same section in the plan.

The adsorber consists of a box-type housing 1, divided into sections 2 by vertical partitions 3, attached to the upper base of the case 4, attached to the lower base of the case, AND: 5, attached to the upper and lower base of the case with a window 6 for gas passage.

In the lower part of the body there are lattices 7, on which sorbent 8 is poured. At one end of the adsorbent along the PVA are located valve boxes of the PVA 9 inlet and the outlet of purified air 10. The fittings for supplying water vapor 11, draining desorbate 12 and condensate are welded to the lower base of the body 13.

The adsorber works as follows.

PVA containing vapors of organic solvents, flows through the valve - the box 9, the grille 7 in section 2, formed by baffles 35 and the wall of the housing, wherein extends upwardly through the sorbent layer 8 follows _r blowing section formed by partitions 4 and 5 and the wall of the apparatus, where the PVA goes already from top to bottom through the sorbent layer and the grid 7. Similarly, the PVA passes through the following sections, the valve box 10 and the purified air is released into the atmosphere. Desorption is performed by supplying water vapor through the nozzle 11, the resulting desorbate is discharged through the 15 cer 12, the formed water condensate is discharged through the nozzle 13.

Claims (2)

Claim 2 1. An adsorber comprising a housing with gas inlet and outlet nozzles, a sorbent layer and vertical transverse partitions, the ends of which are alternately attached to the upper and lower 25th bases of the housing, characterized in that, in order to reduce the metal intensity and height of the apparatus and ease of maintenance, the adsorber it is equipped with a longitudinal vertical partition with a window for the passage of gas attached to the upper and lower bases of the housing. 2. The adsorber according to claim. ^ Characterized in that, in order to make full use of the sorbent and the possibility of carrying out desorption with water vapor, it is provided with connecting horizontal baffles connecting the partitions at the level 40 lower ends of the upper partitions and forming sections with partitions for sorbent. 1366187
