Desiccant regeneration device

Abstract

The invention discloses a desiccant regeneration device, the desiccant regeneration device comprises a wetting box, a soaking box and a drying box which are sequentially communicated with each other,wherein the wetting box is divided into at least two first partition layers arranged up and down through a first seat plate, a feed inlet is arranged on the top-most first partition layer, each firstpartition layer is provided with a steam nozzle, the first partition layers are connected end to end in turn to form a cyclotron circulation channel, a first circulation conveying device is arranged in the circulation channel, a plurality of first scraping plates which are arranged at intervals along a conveying path are arranged on the first circulation conveying device, and the upper edges and the lower edges of the first scraping plates respectively correspond to the upper surfaces of the first seat plates of the upper and lower two adjacent first partition layers. According to the desiccant regeneration device, the desiccant can be wetted, soaked and dried in sequence, and the space of the box body can be fully utilized to wet a desiccant, so that the wetting is uniform, and the efficiency is high.

Description

technical field [0001] The invention relates to the field of desiccant regeneration, in particular to a desiccant regeneration device. Background technique [0002] Silica gel desiccant is a highly active adsorption material, which is usually prepared by reacting sodium silicate and sulfuric acid, and undergoing a series of post-treatment processes such as aging and acid soaking. Silica gel is an amorphous substance, and its chemical formula is mSiO2.nH2O. Insoluble in water and any solvent, non-toxic and tasteless, stable in chemical properties, and does not react with any substance except strong alkali and hydrofluoric acid. At present, the used silica gel desiccant can be put into use again after the regeneration process. It needs to go through the process of wetting, chemical soaking and drying. Specifically, the silica gel desiccant is first adsorbed in water vapor, and after reaching saturation, it is soaked in water for rinsing. Combined with the use of detergent to...

AI Technical Summary

Problems solved by technology

[0003] 1) The desiccant that needs to be regenerated is wetted unevenly when it is accumulated in the wetting mechanism, and the space in the box cannot be reasonably used to wet the desiccant, resulting in low wetting efficiency of the desiccant

[0004] 2) Since the medicine is generally at room temperature, the reaction speed between the medicine and the silica gel desiccant is slow

This causes the semi-finished desiccant output from the feed pipe to accumulate on the side of the soaking tank near the feed pipe

The semi-finished desiccant cannot be fully soaked in the solution in the soaking box, which will reduce the soaking effect of the semi-finished desiccant, and then affect the product quality of the subsequent produced desiccant

At the same time, it is also difficult to extract the semi-finished desiccant far away from the suction pipe with the fixed suction pipe

[0006] 4) The existing semi-finished desiccant will gradually deposit on the bottom of the soaking tank during soaking treatment, and precipitation will occur

This is also not conducive to the full soaking of the semi-finished desiccant, which will affect the product quality of the desiccant

The semi-finished desiccant deposited at the bottom of the soaking tank is difficult to be directly extracted through the suction pipe, and the solution in the soaking tank needs to be drained before it can be taken out, which reduces the production rate of the desiccant

[0007] 5) The desiccant that needs to be regenerated is dried unevenly when it is accumulated in the drying oven, and the space in the drying oven cannot be reasonably used to dry the desiccant. The evaporated water is blocked by the silica gel desiccant and cannot be discharged quickly, resulting in the drying efficiency of the desiccant Low

[0008] The above problems will affect the entire desiccant regeneration process, and the regenerated desiccant has poor reuse effect
