Abstract

The invention relates to the technical field of industrial waste gas recycling and treatment, in particular to a device and a method for treating tail gas containing arsenic steam. The device comprises a sleeve and a cooling water jacket, wherein the sleeve comprises an inner sleeve and an outer sleeve; a gas channel is formed between the outer wall of the inner sleeve and the inner wall of the outer sleeve; the cooling water jacket comprises an outer layer cooling water jacket and an inner layer cooling water jacket; the outer layer cooling water jacket is arranged on the outer wall of the outer sleeve, and the inner layer cooling water jacket is arranged on the inner wall of the inner sleeve. The high temperature tail gas containing the arsenic steam enters the sleeve, flows along the gas channel, and exchanges heat with the sleeve having the cooling water temperature; the arsenic steam is condensed into solid under the low-temperature condition and is attached to the interior of thesleeve, and the rest gas is discharged outside through the gas channel; the device adopts a water cooling structure, thus being low in condensation cost; the device and the method can be used for effectively purifying the arsenic component in the high temperature and high flow tail gas containing the corrosive gas, and recycling the purified arsenic component.

Description

technical field [0001] The invention relates to the technical field of industrial waste gas recovery and treatment, in particular to a treatment device and method for tail gas of arsenic-containing vapor. Background technique [0002] Arsenic, commonly known as arsenic, is a metalloid element, and the elemental arsenic exists in the form of gray arsenic, black arsenic and yellow arsenic, which are three allotropes. Arsenic mainly forms alloys with copper, lead and other metals; arsenic oxide and arsenate can be used as pesticides and wood preservatives; high-purity arsenic is used in semiconductor and laser technology. Arsenic is highly toxic, odorless, tasteless, and carcinogenic, and it is extremely difficult to eradicate toxicity. my country's electronic industry gas standard GB / T 26250-2010 stipulates that the three wastes containing arsenic must be detoxified before discharge. [0003] Exhaust gas containing arsenic particulates including arsenic vapor, N 2 、H 2 and...
