Description

(54) TREATMENT FOR REMOVING HARMFUL: EXTRACTION

- one

This invention relates to bentilations. and can be used for

catching hazardous areas in: metal plating workshops from electroplating or pickling baths and other equipment with a horizontal surface that releases harmful substances. A device for the removal of harmful exudates that are formed during the operation of technological processes in baths is known. Now.on vod.p: 1 side of the outer side,. Bathtubs are extended air ducts with pblgmi sash, size-. . 1 over the bathtub and. having exhaust holes 1 .. -; ..:., ...:,: However, for efficient operation ;. ,

The known device is required. :

Remove large amounts of air. defining significant air exchange in the premises, which was increased by 1st em. power consumption of ventilation systems.

.In order to increase the effectiveness of the trap.

Hazardous casts proposed -, the device is designed to contain. air inlets, air ducts, razggoyozhennae along the sides of the bath over the exhaust and supplied with pivoting

The boxes placed above the flaps and having end faces facing each other have longitudinal slits, and the exhaust holes are made in the lower part of the flaps, the latter and the box are rigidly connected to the 5c exhaust and intake ducts. mi . . :. .

-. PA figs, 1 shows the proposed

device, a longitudinal section f 10 figure 2 - shows the node 1 in figure 1. .,. . A device for removing harmful. discharge j formed during technological processes

in baths 1, contains Y5 located along the sides from the outside .. baths 1 and exhaust air ducts 2; With the great quotations, 3,

placed above bathroom-.1 and available. exhaust holes 4. The device 20 additionally contains inlets

air ducts 5, located along the sides of the bath 1 above the exhaust and .Snab; zn.nnye..potochnymi.votornymi kora; bami b, placed above. The flaps 25 3 and have, from trpci, facing each other, the longitudinal slits 7, and the exhaust holes 4 are made in the inner part of the flaps 3, the latter and the box 6 are rigidly connected to the exhaust and intake ducts.

2 and 5, in V. anne 1 there is located the processed product 8,

Exhaust and intake ducts 2 and 5 are fixed to the sides: x. Baths 1 by means of a hinge 9.. ., .P..

The device operates as follows. In the operating state of the technological process, when the item 8 being processed is in the bath.

1, the flaps 3 and the duct 6 of the junction are horizontal in position, providing cover for the bath 1 in the form of a lid, Front evaporation of the bath .1 together with air .. due to the 5 inlet opening in the air duct 2, created by working. exhaust fan. ...

rum supply air jets flowing out of the slots 7 block the processing of the first product 8, in this position, the exhaust valve 3 forms an intake panel, through the openings 4 of which air is sucked out together with harmful and evaporated baths 1 .

Thus, the presence of a lid on the bath 1, formed by the flaps 3. and the suction boxes 6, virtually eliminates the killing of harmful vapors. SRI from bath 1 to the production ;; the room in the working state of the technological process (the lid is closed) and sharply reduces these allocations 51 in the interoperational space of the technological process, i.e. The effect is increased.

Claims (1)
