Description

Fire metallurgy device for smelting

Technical Field

The utility model relates to a pyrometallurgical field especially relates to a smelt and use pyrometallurgy device.

Background

Pyrometallurgy is a metallurgical process in which an ore or concentrate is subjected to a series of physicochemical changes under high temperature conditions (heat generated by combustion of fuel or electrical energy or heat evolved by some chemical reaction) to separate the metal from gangue or other impurities and obtain the metal.

The existing flue gas treatment method is dry purification, wherein the flue gas is introduced into a cloth bag or a cyclone dust collector or an electrostatic dust collector for treatment, but the method can remove larger dust and carbon particles but is difficult to remove smaller dust and carbon particles.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome prior art's not enough, provide a smelt and use pyrometallurgical device, it regards as the dust carbon granule that filter medium is arranged in detaching the flue gas with the water film, and not only the filter effect is good and equipment is simple, practices thrift manpower and materials.

The utility model provides a its technical problem realize through following technical scheme: the pyrometallurgical device for smelting comprises a smelting furnace, an oxygen side-blown reduction smelting furnace and a fuming furnace which are sequentially connected, and further comprises a pyrometallurgical refining pot, wherein the pyrometallurgical refining pot is respectively connected with a primary crude lead discharge port of the smelting furnace and a secondary crude lead discharge port of the oxygen side-blown reduction smelting furnace; still include the clean room, the clean room top is connected with the chimney, the clean room bottom is passed through the flue and is connected with the smelting furnace, be equipped with the fan between clean room and the flue.

Preferably, a water filtering membrane is arranged in the purification chamber, the water membrane is formed by nozzles which are arranged in a vertically staggered mode, the nozzles are connected through an upper water pipe and a lower water pipe, a circulating water tank is arranged below the water membrane, a filter is arranged in the circulating water tank, and the filtered water is pumped to the nozzles through a water pump.

Preferably, the clean room is made of stainless steel plates or metal plates coated with anticorrosive coatings.

The utility model discloses beneficial effect:

the utility model discloses this technique uses the water film as filter media, and the dust hardly passes the water film, and dust removal effect is good and the working costs is low, and the used material of this technique is ordinary metal, and the dead weight is light, and construction cycle is short, and consequently, the construction cost is far less than the equipment that can reach the ultralow emission requirement of the same kind. Meanwhile, the device is matched with a fan through a pressure transmitter, so that the pressure change in the flue is controllable.

Detailed Description

Example 1:

with reference to the attached drawings of the specification, the embodiment provides a pyrometallurgical device for smelting, which comprises a smelting furnace 1, an oxygen side-blown reduction smelting furnace and a fuming furnace which are sequentially connected, and further comprises a pyrometallurgical refining pot, wherein the pyrometallurgical refining pot is respectively connected with a primary crude lead discharge port of the smelting furnace and a secondary crude lead discharge port of the oxygen side-blown reduction smelting furnace; still include

clean room

2, 2 tops of clean room are connected with

chimney

3, 2 bottoms of clean room are connected with smelting furnace 1 through flue 4, be equipped with the fan between clean room 2 and the flue 4.

Preferably, a water filtering membrane is arranged in the purification chamber 2, the water membrane is formed by nozzles 5 which are arranged in a vertically staggered mode, the nozzles 5 are connected through an upper water pipe and a lower water pipe, a circulating water tank 6 is arranged below the water membrane, a filter is arranged in the circulating water tank 6, and the filtered water is conveyed to the nozzles 5 through a water pump 7.

Preferably, the clean room 2 is made of stainless steel plates or metal plates coated with anticorrosive coatings.

The working process is as follows:

the flue gas that smelting furnace 1 produced is discharged through flue 4, and the flue gas blows in from clean room 2 bottom through the fan, and the flue gas gets into clean room 2 bottom, and shower nozzle 5 utilizes high-pressure nozzle to form two or several water films that stagger flow from top to bottom and from bottom to top, makes the flue gas be close to the vertically and passes the water film, and the dust is washed down by rivers and is got into circulating water pond 6, and clean air passes through chimney 3 and discharges. The device generally becomes the cube or cylinder, and small occupation space is little, and make full use of space does benefit to the installation. The utility model discloses can realize that the water dirt of full coverage mixes, realize dust removal effect and purpose.

This application utilizes the device to make the circulating water form suitable water film, makes dusty flue gas, waste gas filter through this water film, reaches ultralow emission standard, becomes the clean gas that can the evacuation, is applicable to the dust removal workshop section and the tail gas treatment that needs flue gas, waste gas to reach ultralow emission requirement.

Get and press jar 8 to be applied to the pyrometallurgical dust more and the great operating mode of fan load change, flue gas flue 4 with flue get press jar 8 lug connection, get to press the latus rectum big, the flue gas passageway is more unobstructed during the use, and in case long-time after using, get to press the mouth jam, open mediation cutting ferrule ball valve, use the shaft-like thing can conveniently dredge.

Although the embodiments of the present invention and the accompanying drawings are disclosed for illustrative purposes, those skilled in the art will appreciate that: various substitutions, changes and modifications are possible without departing from the spirit and scope of the present invention and the appended claims, and therefore, the scope of the present invention is not limited to the disclosure of the embodiments and the accompanying drawings.
