Suction type ore dissolving acid mist spray tower

Abstract

The invention provides a suction type ore dissolving acid mist spray tower, comprising a liquid storage tank and a tower body, wherein the bottom of the tower body communicates with the top of the liquid storage tank through a first liquid conveying pipe; a gas box is arranged in the tower body, a plurality of gas outlet pipes communicate with the top surface of the gas box, and the bottom of thegas box communicates with a gas outlet of a first gas pump through a first gas pipe; a water curtain disc is arranged above the gas outlet pipes, a first water curtain formed by the water curtain disccorresponds to each gas outlet pipe, and a second water curtain is formed to cover all the gas outlet pipes; the water curtain disc communicates with a second liquid conveying pipe, the second liquidconveying pipe communicates with a water outlet of a booster pump, and a water inlet of the booster pump communicates with the liquid storage tank; and a second gas pump is installed on one side of the tower body, and a gas inlet of the second gas pump communicates with the interior of the tower body through a second gas pipe. According to the invention, acid mist can be purified in a water curtain mode, filtering and purifying effect is guaranteed, recycling can be achieved, and cost is reduced; and in addition, the modes of pressurized gas supply and negative pressure suction are adopted, movement of gas is accelerated, and therefore, filtering efficiency is improved.

Description

technical field [0001] The invention relates to the field of spray towers, in particular to a suction-type ore-dissolved acid mist spray tower. Background technique [0002] Acid mist is a general term for sulfuric acid mist and nitric acid mist. During the copper ore smelting process, especially in the process of extracting copper by extraction and electrowinning, due to the volatilization of a large amount of sulfuric acid, and the copper ore contains a large amount of sulfate and nitrate, during the reaction A large amount of acid mist will be produced under high temperature conditions, and the acid mist distributed in the air will pollute the environment, and the acid mist is highly corrosive, and it will endanger skin health if it is contacted by the human body. irreparable damage. [0003] Therefore, the copper ore smelting workshop needs to be equipped with a special acid mist purification device. The purification process of the traditional acid mist purification d...

[0002] Acid mist is a general term for sulfuric acid mist and nitric acid mist. During the copper ore smelting process, especially in the process of extracting copper by extraction and electrowinning, due to the volatilization of a large amount of sulfuric acid, and the copper ore contains a large amount of sulfate and nitrate, during the reaction A large amount of acid mist will be produced under high temperature conditions, and the acid mist distributed in the air will pollute the environment, and the acid mist is highly corrosive, and it will endanger skin health if it is contacted by the human body. irreparable damage

[0003] Therefore, the copper ore smelting workshop needs to be equipped with a special acid mist purification device. The purification process of the traditional acid mist purification device is relatively complicated, the price is high, and the filtration efficiency is relatively slow. There is still a large room for improvement.
