Description
Technical field:
The utility model relates to the innoxious resource processing technology field of old and useless fluorescent lamp, particularly relates to a kind of old and useless fluorescent lamp harmless resource utilization process for producing line.
Background technology:
Present stage, the fluorescent lamp that brightness is high, energy consumption is low instead of traditional incandescent lamp in majority of illumination field, become the maximum light source of illumination consumption, China also becomes Fluorescent lamp production state maximum in the world and uses state, year fluorescent lamp output more than 2,000,000,000.But because containing 20-50mg mercury in every fluorescent tube, then just there are nearly 20 tons of mercury because can not effectively be recycled in annual discarded fluorescent tube, enter air or flow into water source and soil, great pollution is caused to environment.
The process of old and useless fluorescent lamp harmless resource utilization has two technical barriers; one is the recovery of mercury; mercury part in fluorescent tube exists with gaseous form; a part is attached on fluorescent material and glass in a solid state; current reclaimer and technique; the collection of the mercury of two states can not be taken into account, be subject to production capacity restriction simultaneously, large-scale industrial can not be formed and produce.Two is recovery of fluorescent material, and the fluorescent material recovery method adopted at present mostly is Ultrasonic Cleaning or wet-cleaned, but this kind of cleaning process relates to the process of acid-base waste fluid more, and cleaning performance is poor, and the fluorescent material performance of cleaning out is not good, and cost is higher.
Utility model content
The technical problem that the utility model solves there is provided a kind of old and useless fluorescent lamp harmless resource utilization process for producing line; collect and fluorescent material cleaning separation to solve mercury in old and useless fluorescent lamp; realize the problem that large-scale industrial is produced, reach the object of old and useless fluorescent lamp harmless resource utilization process.
The technical scheme that the technical problem that the utility model solves adopts is:
A kind of old and useless fluorescent lamp harmless resource utilization process for producing line, the negative pressure collecting device mainly comprising preliminary reducing mechanism, mercury separator, metal separation gathering-device, fluorescent material separator and collect for mercury collection and fluorescent material, is characterized in that:

Described metal separation gathering-device comprises tramp iron separator, separating twice device, regrading device;
Described fluorescent material separator comprises the rotary screen that inside is provided with air inlet washer;
Described negative pressure collecting device comprises cyclone collector, pulse dust collector, mercury solidification gatherer, induced draft fan.
Improve as one, described preliminary reducing mechanism is screw crusher.
Improve as one, described separating twice device is Double roll crusher.
Improve as one, described Double roll crusher roll gap is 25-35mm.
Improve as one, described air inlet washer comprises shower nozzle and is connected to the admission line of source of the gas.
Improve as one, described regrading device is rotary screen.
Improve as one, described fluorescent material separator also comprises grader, after being separated for fluorescent material, by oarse-grained fluorescent lamp tube fragment classification process.
Improve as one, described grader is vibrating screen grader.
Owing to have employed technique scheme, compared with prior art, the utility model beneficial effect is: because negative pressure collecting device is connected through pipeline with preliminary reducing mechanism and mercury separator, waste old fluorescence lamp tube is tentatively pulverized the gaseous mercury volatilized instantaneously and is entered negative pressure collecting device through pipeline, and gaseous mercury is separated rapidly; Under the high temperature of the mercury separator being provided with heater bakes, the mercury be attached on fluorescent material and glass gasifies rapidly, enters negative pressure collecting device through pipeline, and solid-state mercury also obtains quick separating and collection; The gaseous mercury obtained enters mercury solidification gatherer through pulse dust collector, and generates more stable mercuric sulphide with curing agent sulphur, avoids mercury pollution.
Carry out stripping cleaning owing to have employed air inlet washer to the fluorescent material be attached on glass, when this mechanical means avoids wet-cleaned, acid-base waste fluid is to the pollution of environment and harm, and production technology is safe and scientific, reduces cost.
This production line runs under negative pressure airtight condition, can stop the volatilization of gaseous mercury, reaches the object of hazardous waste recycling and environmental protection.
