Problems solved by technology

[0009] In addition, failures of recovery equipment utilizing fractional distillation methods may increase and the size of recovery equipment may also increase due to high temperature requirements
[0010] In addition, recovery equipment is less effective at recovering mercury if the gas stream containing mercury vapor is turbulent

Embodiment Construction

[0031] figure 1 is a schematic diagram showing a recycling apparatus according to an exemplary embodiment of the present invention.

[0032] refer to figure 1 , the recovery apparatus includes a crusher 160 , a first collection container 100 a , a cover 102 a , a heater 110 , a tubular unit 120 a , a cooler 130 a , a second collection container 140 a and a pump 150 .

[0033] The crusher 160 includes a plurality of rollers 162 and a blower 164 . The crusher 160 may have two rollers 162 . The rollers are turned opposite to each other so that the rollers 162 crush the fluorescent lamps supplied from the upper part of the crusher 160 . Fragments of the fluorescent lamps are collected in the first collection container 100a. If the distance between the outer surfaces of the rollers 162 is greater than about 5 cm, the size of each fragment of the fluorescent lamp is relatively large, so that it may be difficult for mercury on the fluorescent lamp fragments to evaporate. The dis...

Abstract

In an eco-friendly method of recycling a fluorescent lamp capable of reducing energy consumption and a recycling apparatus for performing the recycling method, broken pieces of fluorescent lamps are heated at a temperature of about 100 DEG C to about 330 DEG C to form a gas containing a mercury vapor. The gas containing the mercury vapor is cooled at a temperature of about -38 DEG C to about 0 DEG C to form a liquid mercury. The liquid mercury is collected. Therefore, the broken pieces of the fluorescent lamps are heated at the temperature no higher than the boiling point of mercury so that an energy consumption and a size of the recycling apparatus are decreased, and a probability for the recycling apparatus to malfunction may also be decreased.

Description

technical field [0001] The present invention relates to a method of recycling fluorescent lamps and a recycling apparatus for carrying out the method. More specifically, the present invention relates to a method of recycling fluorescent lamps capable of reducing energy consumption and not harming the ecological environment, and an apparatus for performing the method. Background technique [0002] When a predetermined voltage is applied to the mercury vapor, the fluorescent lamp can be made to emit light. [0003] The energy consumption of a fluorescent lamp using mercury vapor and the heat generation of the fluorescent lamp are relatively small, so that a flat display device such as a liquid crystal display (LCD) device uses a fluorescent lamp. Examples of fluorescent lamps are lighting lamps, cold cathode fluorescent lamps (CCFL), inner electrode fluorescent lamps (IEFL), outer electrode fluorescent lamps (EEFL), outer inner electrode fluorescent lamps (EIFL), flat fluores...
