Device for treating waste gas in stone coal vanadium extraction maturation pond

Abstract

The invention discloses a device for treating waste gas in a stone coal vanadium extraction maturation pond. The device comprises a device body, and a first gas incoming pipe and a second gas incomingpipe respectively penetrate one side of the device body; an environment-friendly industrial waste gas purifying device comprises a water pump and a water stop valve. Working personnel fills a first purifying chamber with absorbing liquid, starts the water pump and an extract ventilator through an operation panel and opens the water stop valve, the extract ventilator extracts the waste gas in thestone coal vanadium extraction maturation pond into a Y-shaped pipe through the first gas incoming pipe and the second gas incoming pipe, the waste gas enters the first purifying chamber through the Y-shaped pipe which is positioned in the middle of one side of the first purifying chamber to enable the waste gas to be ejected from the absorbing liquid in the first purifying chamber, the water pumpextracts water in the first purifying chamber through a water extraction pipe, and the absorbing liquid is sent back into the first purifying chamber through a liquid storage tank to enable the absorbing liquid to flow in the first purifying chamber, so that contact area of the absorbing liquid and the waste gas can be increased, and purifying effect of the absorbing liquid on the waste gas is improved.

Description

technical field [0001] The invention relates to the technical field of environment-friendly industrial waste gas purification, in particular to a treatment device for waste gas in a stone coal vanadium extraction aging pool. Background technique [0002] Extracting vanadium by aging vanadium-containing stone coal with concentrated sulfuric acid is one of the more environmentally friendly vanadium extraction methods. Many such invention patents have been published, and many documents have also reported this method. Due to the different mineral components contained in vanadium-bearing coal ores, the following problems will occur during the aging process: 1) Sedimentary vanadium-bearing coal ores contain sulfide ores such as pyrite, chalcopyrite, and galena A class of minerals that produce SO during ripening 2 Exhaust gas and sublimated sulfur cause environmental pollution and lead to the death of trees around the plant; 2) Vanadium-containing stone coal usually contains 5-18%...
