Description

TECHNICAL FIELD

[0001] The utility model relates to salt mud recycling technical field, concretely is a kind of salt mud recycling device. BACKGROUND

[0002] In the process of producing chlorine, hydrogen and caustic soda by electrolysis method using salt as main raw material, the mud discharged is called salt mud, which has wide application in industry and is one of the most basic raw materials in chemical industry, known as the mother of chemical industry. The main products in basic chemical industry, such as hydrochloric acid, caustic soda, soda ash, ammonium chloride and chlorine, are mainly produced using industrial salt as raw material.

[0003] The existing salt mud is usually placed in a fixed volume device for drying treatment during recycling and drying processing. This method has limitations and cannot continuously dry process, and it is easy to cause salt mud to agglomerate and affect recycling. During the drying process of salt mud, the gas generated by drying in salt mud carries harmful substances, which can easily pollute the environment when the gas is directly discharged, reducing the environmental friendliness of salt mud recycling and drying treatment.

[0004] A salt mud recycling and drying treatment device with a material turning structure (authorized publication number CN222064332U) is disclosed in Chinese patent. The rotation of the material guide impeller can uniformly feed the salt mud, and the material turning leaf plate can be driven to rotate by the pulley set, so that the salt mud falling on the upper side of the material guide groove plate can be automatically turned and pushed to the right side. The action of the heater allows hot air to pass through the drying head to dry the salt mud, and the excess moisture can be discharged downward through the filter screen plate, so that the device can continuously dry process the salt mud and turn and push the salt mud to avoid agglomeration and improve the efficiency of salt mud recycling and treatment.

[0005] The action of the suction fan can make the suction end absorb the gas evaporated in the drying box, and the gas can be uniformly distributed in the activated carbon filling through the action of the circular arc guide plate, so that the gas can be fully filtered and purified to avoid the spread of harmful gas and cause environmental pollution, and ensure the environmental friendliness of salt mud recycling and drying processing.

[0006] However, it has some disadvantages: with the increase of use time, the activated carbon will gradually saturate and cannot effectively adsorb harmful substances in the gas, which will cause the filtration efficiency to decrease greatly, so that a large amount of untreated gas is directly discharged, polluting the environment. When replacing activated carbon, it needs to be stopped for a long time, which seriously affects the recycling efficiency. UTILITY MODEL CONTENTS
