Problems solved by technology

[0003] In order to solve the problem that the existing vanadium extraction industry mostly adopts direct discharge or simple treatment facilities for roasting flue gas, which can only capture large particles of dust and cannot effectively absorb harmful gases such as chlorine, hydrogen chloride, and sulfur dioxide. The problem that vanadium wastewater cannot be treated, the present invention proposes a treatment method for roasting flue gas and vanadium precipitation wastewater in vanadium extraction production

Embodiment Construction

[0015] The treatment method of roasting flue gas and vanadium precipitation wastewater in the production of vanadium extraction includes 4 steps of wet dust removal, alkali dechlorination, evaporative crystallization, and ammonia desulfurization. These 4 steps use a composite purification tower (such as figure 1 ) to realize, the composite purification tower includes the gas outlet chimney 1, the upper tower body 2, the gas-liquid separator 3, the spiral guide plate 4, the lower tower body 5, the air inlet 6, the spray device 7 and 12, the vacuum suction filter The device 8, the lye tank 9, and the vanadium precipitation waste water tank 10 are characterized in that: the gas outlet chimney 1 is welded on the upper tower body 2; the upper part of the upper tower body 2 is a cone, and the lower part is a cylinder, and the inside of the cone is riveted with gas and liquid Separator 3, the middle and lower part of the cylinder is welded with spiral deflector 4; the upper tower body...

Abstract

The invention provides a method for treating calcination fume and vanadium-deposition waste water in vanadium extracting production, which comprises the following four steps: wet dust removal, alkaline process dechlorination, crystallization by evaporation and ammonia desulfurization. The four steps are realized by utilizing a compound purification tower, thereby solving the problems that the prior vanadium extracting technology often treats the calcination fume by direct discharge or simple treating facilities, can only catch large-grain dust, and can not effectively absorb chlorine, chlorine hydride, sulfur dioxide and other noxious gases so as to cause serious pollution, the exhaust gas can not be discharged according to the standard, and the vanadium-deposition waste water can not be treated.

Description

technical field [0001] The invention relates to a comprehensive treatment technology for roasting flue gas and vanadium precipitation wastewater in vanadium extraction production. Background technique [0002] The existing vanadium extraction industry mostly adopts direct discharge or simple treatment facilities for roasting flue gas, which can only capture large particles of dust and cannot effectively absorb harmful gases such as chlorine, hydrogen chloride, and sulfur dioxide. Can't handle it. Contents of the invention [0003] In order to solve the problem that the existing vanadium extraction industry mostly adopts direct discharge or simple treatment facilities for roasting flue gas, which can only capture large particles of dust and cannot effectively absorb harmful gases such as chlorine, hydrogen chloride, and sulfur dioxide. To solve the problem that vanadium wastewater cannot be treated, the present invention proposes a treatment method for roasting flue gas an...
