A circulation type hanging wall plate pressure spray drying tower

Abstract

The invention discloses a circulating suspension wallboard pressure spray drying tower. The circulating suspension wallboard pressure spray drying tower includes a hot air inlet, a spraying device, aconveying device and a recycling device, wherein the hot air inlet is formed in the top of the drying tower; the lower portion of the drying tower is provided with the spraying device; the spraying device comprises a hot air distribution pore plate and a drying tower wallboard arranged at the lower portion of a liquid mist nozzle; a door manhole is arranged next to the spraying device; the conveying device comprises a movable suspension wallboard; the movable suspension wallboard comprises a circulating suspension conveyor and a suspension steel plate; the lower portion of the movable suspension wallboard is provided with the recycling device; a whirlwind hole plate with an opening facing the inclined top is arranged on the inner side of an annular air passage wallboard; a door manhole isarranged in the middle of the annular air passage wallboard; a rotary disk type protein powder collecting device is arranged at the bottom of the drying tower; micro-positive-pressure low-temperatureair supply holes are formed in the space of a bottom plate and an inclined receiving turntable; and a return air hole and a heat exchange passage are arranged at the upper portion of the space. According to the circulating suspension wallboard pressure spray drying tower, the problem of adhesion to a wall is solved, the waste of materials is greatly reduced, products are protected against the pollution of materials adhering to the wall, energy is saved, and the drying tower can stably perform production for a long time.

Description

technical field [0001] The invention relates to the technical field of drying tower equipment, in particular to a circulation type hanging wall plate pressure spray drying tower. Background technique [0002] At present, the main problem of the spray dryer (especially the pressure drying tower) is that it has not solved the problem of reducing energy consumption and avoiding wall hanging, which has caused a lot of waste of resources and loss of production stoppage in actual production. [0003] Using pressure spray drying to produce feather enzymatic protein, because the solid particles of the slurry and the feather stalk fibers that have not been completely hydrolyzed cannot be completely eliminated, there is still the problem of clogging of the nozzle of the drying tower during the production process, resulting in spraying and serious problems. Hanging on the wall, it is very difficult to remove the scorched protein powder agglomeration, and sometimes it needs to be rinsed...

AI Technical Summary

Problems solved by technology

Due to the limited matching between the existing secondary drying equipment and the drying tower, it is necessary to further develop a special secondary dryer for protein powder drying

[0006] (2) Serious wall hanging

The product is polluted by coking particles hanging on the wall, so it is necessary to stop production and clean the tower, thereby reducing the effective utilization rate of the equipment

[0007] (3) Single function

Usually, most of the design is based on professional division of labor. There are single equipment such as drying tower, energy saver, cyclone dust collector, bag filter, and odor removal device, and then connected by pipes and valves. The pipes are complicated and there are many consumables. , the equipment is bulky and requires a tall workshop or site space

And due to the connection of each independent device, a lot of intermediate conversion links are added, the structure of the system is complicated, and it is inconvenient to use

[0008] (4) Domestic drying equipment attaches great importance to the development of the whole machine, lacks research on supporting technologies, seriously lacks on-line testing instruments and equipment, lags in the collection of various process parameters, and incomplete system feedback. The existing drying equipment has not really reached the best process state. There is still a gap compared with the international advanced energy consumption indicators in terms of energy saving effect
