Problems solved by technology

Therefore, if mercury is recycled and disposed of improperly, it will cause great harm to the ecological environment.
[0004] At present, the disposal methods of mercury-containing lamp tubes mainly include incineration and recycling methods. The incineration method will cause mercury vaporization in the mercury-containing lamp tubes and easily cause secondary pollution; the recycling method has a large demand for mercury-containing lamp tubes, and the initial construction investment is large. And the operating cost is high. If there is not enough waste mercury-containing lamp tubes, sufficient profits cannot be guaranteed, and it is not feasible

Embodiment 1

[0026] For the specific disposal structure of mercury-containing lamps, see figure 1 .

[0027] Disposal steps for mercury-containing lamps include the following:

[0028] (1) Sodium sulfide (sulfur or thiourea), water, cement, and sand and gravel are mixed and stirred to make concrete. The proportion of sand and gravel is mercury-containing lamp tube: sand and gravel = 1:30, and the ratio of concrete is sodium sulfide (sulfur or thiourea). Thiourea): water: cement: gravel (sand: gravel = 3:5) = 0.01:1:2.5:6.

[0029] (2) Open the top cover of the tonnage barrel, pour the pre-prepared concrete into the open tonnage barrel, make the sand and gravel material cover the bottom of the tonnage barrel, and the thickness of the bottom concrete is 20cm.

[0030] (3) Put mercury-containing lamps in the tonnage (placed horizontally or vertically). When placing the lamps, the internal space of the tonnage should be used as much as possible. There should be a 10cm space on the side of t...

Abstract

The invention discloses a disposal structure and disposal method for mercury-containing lamp tubes, and relates to the technical field of disposal of discarded mercury-containing lamp tubes. A plurality of discarded mercury-containing lamp tubes are gathered and placed in the center of a ton barrel, and a discarded mercury-containing lamp tube aggregate is formed by the multiple discarded mercury-containing lamp tubes; a void space is formed between the aggregate and the side wall of the ton barrel, and is also formed between the aggregate and the bottom and upper parts of the ton barrel; thesurface of the discarded mercury-containing lamp tube aggregate or the surfaces of the mercury-containing lamp tubes are covered with a sulfide layer; and the gaps between the discarded mercury-containing lamp tubes in the discarded mercury-containing lamp tube aggregate are filled with sulfide-containing concrete, the void space between the discarded mercury-containing lamp tube aggregate and theton barrel is also filled with the sulfide-containing concrete, the sulfide-containing concrete is integrally solidified, so that the discarded mercury-containing lamp tubes are fixed and embedded into the sulfide-containing concrete. According to the disposal structure, the mercury diffusion can be effectively prevented.

Description

technical field [0001] The invention belongs to the technical field of environmental protection and relates to the disposal of scrapped mercury-containing lamp tubes. Background technique [0002] At present, the mercury content of a T12 mercury-containing lamp tube with a diameter of 36 mm in my country is about 25 to 45 mg; a T5 mercury-containing lamp tube with a diameter of 16 mm contains about 20 mg of mercury; Compact mercury-containing lamps contain approximately 10 mg of mercury. In recent years, my country has produced about 900 million mercury-containing lamps annually. Based on the average mercury content of each lamp being 30 mg, the total amount of mercury in the mercury-containing lamps produced in my country each year is about 27 tons. [0003] The scrapped lamp tubes are discarded at will or mixed in a large amount in domestic garbage, which can easily cause the diffusion of mercury after the lamp tube is broken, seriously endangering the health of residents....
