Description

The invention relates to filter sorbers for cleaning process air from gas impurities and can be used in the nuclear, chemical, medical and metallurgical industries.

Known adsorber [A.S. USSR for the invention No. 1581357. Adsorber. Stated 08/13/1987. Published 07/30/1990].

The adsorber consists of a vertical cylindrical body with coaxial layers of adsorbent placed in it on the base plate: external and internal. The layers of the adsorbent are separated from each other by the interlayer space of the adsorber and are respectively limited by a cylindrical body and a perforated cylinder (on the outer layer) and perforated cylinders (inner layer). A nozzle is tangentially located for supplying a gas stream containing the adsorbed component and into the annulus in the lower part of the adsorber body above the base plate, and a nozzle is tangentially mounted for supplying a desorbing stream to the upper part of the interlayer space.

A disadvantage of the known device is the design complexity and inconvenience of assembly.

The closest technical solution is the adsorber, considered in the following copyright certificate [A.S. USSR for the invention of the Russian Federation No. 1353478. Adsorber. Stated May 25, 1985. Published 11/23/1987]. The adsorber contains a housing, a tube, consisting of tubes made of elastic material, an internal cavity of the housing (annular cavity) in communication with a source of overpressure of the working medium and a source of rarefaction, an additional annular sorption cavity with channels made with walls of elastic material, and equipped with restrictive annular partitions in contact with it, providing predetermined limit values of the oscillations of the distance between them and giving the required my configuration.

A disadvantage of the known technical solution is that the adsorber does not provide for the possibility of replacing the spent sorbent with a new one.

The objective of the invention is to eliminate this drawback, namely, in providing the possibility of replacing the spent sorbent in the cassette with a new sorbent.

The technical result of the invention is to expand the functionality of the installation.

To solve this problem in a bulk filter sorber, consisting of a cylindrical body, a bottom and a removable cover, lower and upper cassette plates, inlet and outlet nozzles, and at least one cartridge placed vertically inside the filter sorber housing installed between the lower and upper cassette plates with the emphasis on the end parts having a cylindrical body and equipped with a sorbent, it is proposed:

- in the upper and lower cassette plates, execute at least one channel corresponding to the position of the sorbent in the cassette;

- install the inlet and outlet nozzles on the filter-sorber body;

- place the inlet pipe above the upper cassette plate, and the outlet pipe - under the lower cassette plate.

In particular cases of device execution, the following is proposed:

Firstly, as a sorbent use granular organic material of the SKT-3 brand and (or) silica gel of the KSKG type.

Secondly, the upper and lower layers of the sorbent are made of KSKG type silica gel, and the intermediate layer of the sorbent is made of granular organic material of the SKT-3 brand.

The technical result consists in expanding the functionality due to the possibility of extracting the sorbent from the filter sorbent cassettes.

A schematic diagram of one embodiment of a bulk filter sorbent is shown in FIGS. 1 and 2, which show a portion of the longitudinal axial and cross sections of the filter sorbent, respectively. The following notation is used in the figures: 1 - upper cassette plate; 2 - inlet pipe; 3 - outlet pipe; 4 - bottom; 5 - channel of the upper cassette; 6 - channel lower cassette; 7 - cassette case; 8 - filter-sorber body; 9 - a cover; 10 - lower cassette plate; 11 - sorbent.

The bulk filter sorber consists of a cylindrical body 8, a bottom 4 and a removable cover 9, a bottom 10 and a top 1 of cassette plates, an inlet 2 and an outlet 3 nozzles, and at least one cartridge. The cartridge is placed vertically inside the housing 8 of the filter sorbent, is installed between the bottom 10 and the top 1 of the cassette plates with the end parts resting on them, has a cylindrical body 7 and is equipped with sorbent 11.

In the upper 1 and lower 10 cassette plates made at least one channel 5, 6, corresponding to the position of the sorbent 11 in the cassette.

Input 2 and output 3 nozzles are installed on the housing 8 of the filter-sorber. The inlet pipe 2 is located above the upper cassette plate 1, and the outlet pipe 3 is under the lower cassette plate 10.

In special cases, the performance of the bulk filter sorber is as follows.

First, as the sorbent 11, granular organic material of the SKT-3 brand and (or) silica gel of the KSKG type are used.

Secondly, the upper and lower layers of sorbent 11 are silica gel of the KSKG type, and the intermediate layer of sorbent 11 is granular organic material of the SKT-3 brand.

The bulk filter sorber operates as follows. The cleaned air stream enters the flow part of the device through the inlet pipe 2, sequentially passes through the channel 5 in the upper cassette plate 1, the cassette body 7, moves from top to bottom in the channels formed by the granules of the sorbent 11, is cleaned by interacting with the sorbent 11 in them, the cleaned air stream exits the cassette through channel 6 in the lower cassette 10 and exits the flow part of the filter-sorber through the outlet pipe 3

This scheme of movement of the cleaned stream as a result of dynamic pressure eliminates the occurrence of a fluidized bed of sorbent 11, which contributes to a more efficient cleaning of the air stream.

During operation of the filter sorbent, a relatively simple procedure for replacing the spent sorbent 11 is carried out while maintaining the components of the structural elements of the filter sorbent, for example, cassettes, bottom 10 and top 1 of cassette plates.

An example of a specific implementation of the filter sorber bulk type

A prototype of a filter-sorber was made and tested.

The filter sorber has the following characteristics:

Nominal air (gas) performance,

m ³ / h 1500 The cleaning efficiency for methyl iodide,% not less than 99.0

Loss of excess pressure on the pumping flow

air, Pa no more than 2200

The relative humidity of the cleaned air

flow% up to 95 Maximum working temperature, ° С 150 Dimensions, mm 1300 × 800 Weight kg 300 Number of cassettes one

The filter sorbing component parts have the following characteristics:

- cassette case 7: outer diameter - 1020 mm, inner diameter - 1016 mm, height - 600 mm;

- filter sorbing housing 8: inner diameter - 1094 mm, height - 800 mm ;.

- sorbent 11: the maximum granule size of coal type SKT-3 is 1-2 mm; bulk porosity - not less than 70%; effective surface - not less than 1000 m ² / g; packing of granules in the cartridge is tight.

The diameter of the inlet 2 and outlet 3 nozzles - 150 mm.

The upper and lower layers of sorbent 11 are silica gel of the KSKG type, and the intermediate layer of sorbent 11 is granular organic material of the SKT-3 brand.

The thickness of the layers of sorbent 11 in the cartridge is identical.

Part of the area of the lower 10 and upper 1 cassette plates located respectively above and below the sorbent 11 is made in the form of wire mesh with a diameter of 0.8 mm stainless steel with a mesh cell size of 0.6 mm × 06 mm.

The tests of a prototype bulk filter sorber confirmed its performance and technical characteristics, including the convenience of replacing the spent sorbent.
