The technical process of the lime equipment is to add raw quicklime from the loader to the silo, evenly add it to the jaw crusher through the vibrating feeder, and crush it to about 30-50 mm. The dust generated during the crushing process of the equipment is introduced into the pulse bag filter outside the workshop by the induced draft fan through the dust cover of the jaw crusher, and the calcium oxide powder of the dust collector should be cleaned once a week.
The hydrated lime equipment adopts a double-shaft stirring structure, which has various functions such as stirring, crushing and agglomeration, and self-cleaning. Its unique paddle and stirring formula make the quicklime and water mix evenly, the reaction is sufficient, and it plays a role in the agglomeration generated during the reaction.
HYDRATED LIME EQUIPMENT
The feed port of the digester is designed with a screw feed propeller to facilitate material transportation. In order to prevent the backflow of dust generated in the digestion process, the equipment is equipped with a special discharge port for steam and dust, which can be discharged to a special dust removal system through connecting pipes, and is used in conjunction with the DMC pulse dust removal Q device with the hydrated lime equipment, which can handle quicklime well. Dust and harmful gases produced during digestion. Waste dust and lime can be reused after use, and the environment has no dust pollution, which meets the requirements of environmental protection development.
The quicklime crushed by the hydrated lime equipment is lifted by the bucket elevator to the lime silo at the upper part of the digestion tank in the digestion workshop. The quicklime is evenly fed into the digester through the plug-in valve at the lower part of the lime silo and the weighing feeder (the feeding speed is 5t/h). At the same time, water was added to the digester at a ratio of 133603.5 (17.5 m3/h).
