Description
Technical Field
The utility model belongs to the field of desulfurization waste liquid treatment processes, and particularly relates to a waste liquid spray gun for a combustion acid-firing process.
Background
In the desulfurization waste liquid treatment process, the sulfur-containing waste liquid is sprayed into an incinerator, and various components in the waste liquid are incinerated and decomposed by utilizing the high-temperature environment formed in the incinerator by the combustion heat release of fuel gas, SO that the sulfur-containing waste liquid is prepared 2 Then SO in the furnace gas is processed by an acid making process 2 Preparing concentrated sulfuric acid.
The decomposition chemical reaction formula of each main component of the desulfurization waste liquid is as follows:
NH4SCN + 3O 2 —— CO 2 + O 2 + N 2 + 2 H 2 O + ΔH(>0)
2 (NH 4 ) 2 S 2 O 3 + 5 O 2 —— 4 SO 2 + 2 N 2 + 8 H 2 O + ΔH(>0)
(NH 4 ) 2 SO 4 + O 2 —— SO 2 + N 2 + 4 H 2 O + ΔH(<0)
2(NH 4 ) 2 SO 3 + 3 O 2 —— 2 SO 2 + 2 N 2 + 8 H 2 O + ΔH(<0)
from the equation, sulfuric acid cleavage is itself accomplished and the reaction product is also capable of evolving oxygen. Therefore, in a furnace temperature environment high enough, the cracking reaction can be completed quickly as long as atomization is sufficiently fine. The waste liquid decomposition can not be completed completely by itself, but a large amount of oxygen is needed to participate, so compared with sulfuric acid decomposition, the technical key points of waste liquid treatment comprise not only one technical key point of waste liquid atomization, but also a second technical key point of contact mixing of the atomized waste liquid with air, and the contact and mixing are more important for the completion of decomposition.
In the prior art, as shown in fig. 4, the waste liquid spray gun used at present is not provided with an independent air supply and distribution system, only a small amount of cooling air is fed, even no cooling air is fed, and the air supplied from a lower burner is used for decomposing the waste liquid, so that the spray gun structure and equipment arrangement delay the mixing time of the waste liquid and the air on one hand, and greatly limit the contact area of the waste liquid and the air on the other hand, so that the decomposition reaction of the waste liquid is greatly delayed, even the reaction is not completed until the reaction is completed, and the waste liquid leaves the incinerator, so that components such as sulfur which cannot be completed in the waste liquid are deposited on the surface of subsequent equipment, and even the channel is blocked; there is an urgent need for a method that can solve such a problem.
