Novel drying tower

Abstract

A novel drying tower solves the problems that high-temperature drying particles in the prior art are easy to scale and accumulate on the inner wall of equipment, so that the product quality is influenced, the scale removal work difficulty is high, and the operation and maintenance cost is high. The device comprises an upper cylindrical barrel body and a lower conical barrel body, and is characterized in that the outer wall and the inner wall of the cylindrical barrel body and the conical barrel body are respectively provided with an outer heat preservation layer and an inner cold air interlayer which are communicated with each other; and the lower end of the cold air interlayer at the inner side of the conical barrel body is connected with a cold air inlet, and the upper end of the cold air interlayer at the inner side of the cylindrical barrel body is connected with a cold air outlet; an atomizing liquid inlet is formed in the middle of a hot air distributor at the top of the cylindrical barrel body, and a drying particle discharge hole is formed in the bottom of the cylindrical barrel body; a tower wall sweeper composed of an upper cleaning pipe and a lower cleaning pipe is further arranged in the drying tower body. The device is reasonable in design and compact in structure, and can effectively prevent scale accumulation of dry particles on the inner wall of equipment, the heat transfer effect is good, the scale removal is convenient, the production efficiency is high, and the operation is stable and reliable.

Description

technical field [0001] The invention belongs to the technical field of high-efficiency separation and purification, and specifically relates to a new type of drying machine with good heat transfer effect, which can effectively prevent high-temperature drying particles from sticking to the wall, ensure product quality, have good scale cleaning effect, low labor intensity, high production efficiency, and stable and reliable operation. tower. Background technique [0002] In the existing atomization drying equipment, hot air (about 200°C) needs to be continuously fed into the interior to heat and dry the atomized liquid and discharge it through the outlet at the bottom, so high-temperature dry particles are easy to scale on the inner wall of the drying equipment Accumulation, and then deterioration, affecting product quality. In addition, it is difficult and labor-intensive to clean the scale after the inner wall of the drying equipment is scaled, which increases the operation...

Problems solved by technology

[0002] In the existing atomization drying equipment, hot air (about 200°C) needs to be continuously fed into the interior to heat and dry the atomized liquid and discharge it through the outlet at the bottom, so high-temperature dry particles are easy to scale on the inner wall of the drying equipment Accumulation, and then deterioration, affecting product quality

In addition, it is difficult and labor-intensive to clean the scale after the inner wall of the drying equipment is scaled, which increases the operation and maintenance cost of the equipment, and even has the problem that the scale cannot be cleaned due to structural reasons, which often leads to the forced shutdown of the drying equipment , seriously affecting production
