Recycling and processing equipment of waste and old fluorescent lamp

Abstract

The invention relates to recycling and processing equipment of a waste and old fluorescent lamp, belonging to the technical field of the recycling and processing of fluorescent lamps. The equipment comprises a smashing device, a separating device, a support, a bag-type dust remover, a screw conveyer, an air separation device, an air close discharging valve and an electric control device. The smashing device and the air separation device are respectively installed at two ends of the support and connected through the screw conveyer installed at the top of the support. The separating device and the bag-type dust remover are installed at one side of the support, wherein the separating device is connected with the screw conveyer through two mercury vapor recycling pipelines, and the bag-type dust remover is connected with the air separation device through a fluorescent powder recycling pipeline. Through the process that the waste and old fluorescent lamp is smashed and heated in a sealed environment, mercury vapor is absorbed by active carbon and then delivered to a special factory for recycling and purifying; and meanwhile, the glass, fluorescent powder and metal material of the waste and old fluorescent lamp are recycled, the recycling and processing equipment of the waste and old fluorescent lamp can be used for solving the problems that the environment is polluted by mercury in the traditional waste and old fluorescent lamp and waste and old materials are not recycled and utilized.

Description

technical field [0001] The invention relates to recycling and processing equipment for waste fluorescent lamps, which belongs to the technical field of fluorescent lamp recycling and processing. Background technique [0002] Compared with incandescent lamps, fluorescent lamps have the advantages of high brightness and energy saving. At present, governments of various countries are actively promoting their use. However, after the service life of the fluorescent lamp expires, there will be a problem that the brightness will become dim, and eventually it will not be able to emit light and be damaged, so the fluorescent lamp has to be replaced again. Damaged fluorescent lamps are usually landfilled with domestic waste after they are replaced. However, since fluorescent lamps are made of glass tubes and aluminum alloy tubes at both ends, and the glass tubes are filled with mercury and phosphor powder, after the fluorescent lamps are broken or landfilled, glass fiber, Aluminum al...

AI Technical Summary

Problems solved by technology

It not only solves the problem of environmental pollution after waste fluorescent lamps are broken or landfilled, but also recycles the materials of waste fluorescent lamps. It is a waste fluorescent lamp recycling and processing equipment with good social and economic benefits.
