Abstract
The utility model discloses an acid gas absorption device for silver dissolution, which belongs to the chemical technical field. The acid gas absorption device mainly comprises a stainless steel reaction kettle, an electrical heating oil jacket, an acid gas scrubber and an alkali liquor absorber, wherein the stainless steel reaction kettle is provided with a condenser; in addition, the acid gas absorption device is structurally characterized in that an acid gas discharge hole formed on the stainless steel reaction kettle with the condenser is sequentially communicated with the acid gas scrubber, the alkali liquor absorber, an activated carbon absorber and a circulating water system; and the circulating water system comprises an injector head, an injection pump and a water tank. The acid gas absorption device has the advantages of less raw material consumption, simple structure, high acid gas absorption efficiency and no environment pollution.
Description
Technical field
The utility model relates to a kind of sour treatment of waste gas device that contains, and specifically a kind of acid gas absorption plant of silver dissolving belongs to technical field of chemistry.
Background technology
The method of red fuming nitric acid (RFNA) (chemical pure) thin up heating for dissolving is generally adopted in the dissolving of noble metal silver.Because the silver course of dissolution produces a large amount of sour gas nitrogen dioxide, nitrogen dioxide is excessive, contaminated environment not only, and etching apparatus influence service life of equipment, also causes bigger raw materials consumption to the dissolving of silver simultaneously.At present, use fountain washer and packed tower that acid gas is handled during acid gas absorbs usually, the acid gas absorption efficiency is lower, and effect is all not ideal.
The utility model content
It is few that task of the present utility model provides a kind of raw materials consumption, simple in structure, acid gas absorption efficiency height, the acid gas absorption plant of silver dissolving free from environmental pollution.
For realizing above-mentioned task, technical solution of the present utility model is:
A kind of acid gas absorption plant of silver dissolving, mainly be made of the stainless steel cauldron with condenser, electric oil chuck, acid gas washer, alkali lye absorber, its design feature is that the acid gas tap with stainless steel cauldron of condenser is connected with acid gas washer, alkali lye absorber, active carbon adsorber and the circulation that is made of injector head, jet pump and water tank successively.
Because the utility model has adopted three grades to reclaim absorption, greatly reduced the raw materials consumption in producing, acid gas absorption efficiency height has prevented that effectively acid gas is excessive, has prolonged the service life of equipment, and is free from environmental pollution.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of acid gas absorption plant of silver dissolving, mainly be made of the stainless steel cauldron 1 with condenser 3, electric oil chuck 2, acid gas washer 4, alkali lye absorber 5, the acid gas tap of the condenser 3 on the stainless steel cauldron 1 is connected with acid gas washer 4, alkali lye absorber 5, active carbon adsorber 6 and the circulation that is made of injector head 9, jet pump 8 and water tank 7 successively.
