SU1308365A1 - Scrubber for catching dust containing iron - Google Patents

Abstract

The invention relates to the purification of gas from dust, can be used to clean cupola gases and gases of electric steel-smelting furnaces and improves the efficiency of trapping fine iron containing dust. The scrubber consists of a chamber of dusty air 3, sprinklers 4, a gas supply nozzle 2, a nozzle of clean gas outlet 8, a dividing grid 5 with pipes, 6, made of a larger diameter than the inlets of the dividing grid 5. Inside the pipes 6 longitudinal permanent magnets are installed 7, which makes it possible to carry out the secondary spraying of the water – slurry mixture and, accordingly, to carry out additional precipitation of the pier and wash it from the surface of the permanent magnets 7. 1 Il. € (L u / ///// f // 7 / //////////// / u / / u / ////// f x-fl 00 o eo 00 a:: l

Description

The invention relates to the field of gas cleaning from dust and can be used to clean cupola gases and gases of electric steel-making furnaces.

The aim of the invention is to increase the efficiency of trapping fine iron containing fluids,

The drawing shows a general scrubber scheme for trapping fine iron oxide dust,

The scrubber for trapping fine iron dust contains a cylindrical chamber 1, a gas supply pipe 2, a crude gas chamber 3 in which the sprinklers 4 are located, a horizontal grating separator 5 that splits the scrubber into two parts, scrubber pipes 6 magnets 7, a clean gas outlet pipe scrubber 8; sludge outlet pipe (chute) 9.

The device works as follows.

The dusty gas through the pipe 2 is introduced into the chamber 3 of the dusty gas, located in the upper part

housing 15 in the center of which is located the sprinklers 4. Irrigation produces with a counter to the flow of dusty gas. In this case, there is an intensive wetting of dust particles contained in the gas. The main part of the dust precipitates as sludge onto the grid 5 and enters the pipes 6 through the holes. Since the pipes 6 are made with a larger diameter than the holes of the grid 5, there is a sharp drop in the rate of water and wastes. - th stream and swirling

(turbulization), which leads to additional irrigation with water flow. . The elusive (nonwettable) fine dust falls on flat -, 5 permanent magnets 7 and is deposited on both sides of it, followed by wash-off with a stream of streams and flows along chute 9 into a tank. Purified gas through the scrubber outlet O 8 is released to the atmosphere.

The main purpose of reducing the diameter of the holes in the separation grid compared to the diameters of the pipes 6 is to re-spray the water-slime mixture and direct it across the entire cross-section of the pipes to further irrigate the dust-air flow in order to further precipitate dust and flush out the collected dust from the surface of the permanent magnets installed in the pipes.
