Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of cyclone separator, more specifically, the utility model relates to a flash drying machine cyclone separation device. BACKGROUND

[0002] The flash drying machine is a new continuous drying equipment integrating drying, crushing and screening, and is suitable for drying filter cake, paste and dilute slurry. After drying the materials, the flash drying machine needs to separate dust through a cyclone separator. The cyclone separator mainly causes rotational movement through tangential introduction of airflow, so that fixed particles or liquid drops with large centrifugal force are thrown to the outer wall to separate, thereby achieving the purpose of separation.

[0003] However, the existing flash drying machine cyclone separation device has single function. After drying and heating, some harmful gases are generated from part of the raw materials. The current cyclone separation device is not convenient for purifying and cooling the gas, so that the temperature of the working environment continues to rise, and the harmful gas also affects the health of the workers.

[0004] For example, a flash drying machine cyclone separation device is disclosed in Chinese patent No. CN202123280853.X. The hot gas after dust removal enters the water tank through the gas outlet pipe. The gas distribution net plate uniformly divides the gas into multiple strands and filters the fine particles in the gas. The multiple strands of gas uniformly contact the activated carbon layer, so that the activated carbon layer effectively adsorbs the harmful substances in the gas. The purified and adsorbed gas enters the heat exchange pipe through the gas collecting cover. The heat exchange pipe contacts the water in the water tank, so that the water can be heated. The water vapor generated after heating is sucked into the steam pipe by the air pump. The water vapor is sprayed from the air jet head. The water vapor and dust are combined to increase the gravity of the dust, so that the dust can quickly fall, improve the gas-solid separation effect, and reduce the temperature of the gas exhaust.

[0005] However, when the structure is actually used, although the mixture of water vapor and dust can accelerate the falling speed of the dust, the mixture of the wet dust will adhere to the inner wall of the device. Once the high-temperature condensate is accumulated, it is difficult to handle and affects the subsequent use of the device. In view of this, the utility model provides a flash drying machine cyclone separation device. UTILITY MODEL CONTENTS
