Description
Technical field
The utility model relates to a kind of pickling tower, belongs to the technical field of chemical industry equipment.
Background technology
In MTMS production process, due to the effumability of raw material methyl trichlorosilane and carrying secretly of air-flow, in its byproduct of reaction hydrogen chloride gas, a certain amount of methyl trichlorosilane impurity can be contained.
Prepare in hydrochloric acid process at this hydrogen chloride gas of absorption, solid particle (methane-siliconic acid) is produced because methyl trichlorosilane can be hydrolyzed, cause the blocking of falling-film absorber, so can not directly absorb, after needing the mode of hydrogen chloride tail gas pickling to be carried out washing, purifying, ability is by falling film absorption, makes clean concentrated hydrochloric acid
Due to the existence of solid slag, although packed tower clean result is good, very easily block, so pickling tower generally adopts tower plate structure, but its clean result is not good, in order to ensure clean result, just need to use a large amount of hydrochloric acid circulation cleanings, significantly increase the workload of follow-up Separation of Solid and Liquid.
Utility model content
For the above-mentioned technical problem of prior art, the purpose of this utility model is to provide a kind of pickling tower, overcomes the extremely susceptible to plugging defect of existing packed tower, and ensure that clean result.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of pickling tower, comprise pickling tower body, described pickling tower body comprises joint tower, lower joint tower and tower reactor, and described upper Jie Tanei is provided with random packing layer, and described lower Jie Tanei is provided with rotating stream tray structure; Described upper joint tower top is provided with acid inlet, and upper joint top of tower is provided with gas outlet, and described lower joint tower bottom is provided with air inlet, is provided with recycle acid mouth, is provided with acid mouth bottom described tower reactor between described upper joint tower and lower joint tower; Described rotating stream tray structure comprises left-handed flow structure and dextrorotation flow structure, described left-handed flow structure comprises several left rotating stream tray be parallel to each other, described dextrorotation flow structure comprises several right rotating stream tray be parallel to each other, described left rotating stream tray and right rotating stream tray cross-cutting distribution.
The beneficial effects of the utility model are as follows:
Pickling tower of the present utility model, random packing layer and rotating stream tray structure is provided with in pickling tower body, take into account the advantage of stuffing washing tower and column plate scrubbing tower, namely ensure that the effect of washing, also overcome the extremely susceptible to plugging defect of existing packed tower, decrease the amount of the hydrochloric acid needed for washing, greatly reduce the workload of follow-up Separation of Solid and Liquid.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Wherein, 1 be upper joint tower, 2 be lower joint tower, 3 be tower reactor, 4 be acid inlet, 5 be gas outlet, 6 be air inlet, 7 be acid mouth, 8 be recycle acid mouth, 9 be random packing layer, 10 be left rotating stream tray, 11 for right rotating stream tray.
Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is further described, but protection domain of the present utility model is not limited to this.
As shown in Figure 1, pickling tower of the present utility model, comprises pickling tower body, and pickling tower body comprises joint tower 1, lower joint tower 2 and tower reactor 3, is provided with random packing layer 9 in upper joint tower 1, is provided with rotating stream tray structure in lower joint tower 2; Upper joint tower 1 top is provided with acid inlet 4, and upper joint tower 1 top is provided with gas outlet 5, and lower joint tower 2 bottom is provided with air inlet 6, is provided with recycle acid mouth 8, is provided with acid mouth 7 bottom tower reactor 3 between upper joint tower 1 and lower joint tower 2; Rotating stream tray structure comprises left-handed flow structure and dextrorotation flow structure, left-handed flow structure comprises several left rotating stream tray 10 be parallel to each other, dextrorotation flow structure comprises several right rotating stream tray 11 be parallel to each other, left rotating stream tray 10 and right rotating stream tray 11 cross-cutting distribution.
After reaction end gas enters from air inlet 6, haptoreaction abundant with the hydrochloric acid sprayed from top to bottom, the hydrogen chloride gas after washing, purifying is discharged to gas outlet 5.Clean hydrochloric acid sprays from acid inlet 4, carries out washing, purifying together with the recycle acid in tower to gas, and a hydrochloric acid part of having washed uses as recycle acid, and a part is then expelled to solid-liquid separator, isolates clean hydrochloric acid and recycles.
Pickling tower of the present utility model, random packing layer 9 and rotating stream tray structure is provided with in pickling tower body, take into account the advantage of stuffing washing tower and column plate scrubbing tower, namely ensure that the effect of washing, also overcome the extremely susceptible to plugging defect of existing packed tower, decrease the amount of the hydrochloric acid needed for washing, greatly reduce the workload of follow-up Separation of Solid and Liquid.
Above-described embodiment only illustrates inventive concept of the present utility model for explaining, but not the restriction to the utility model rights protection, all changes utilizing this design the utility model to be carried out to unsubstantiality, all should fall into protection domain of the present utility model.
