Description

Breaking device and treatment equipment for mercury-containing fluorescent tube Technical Field The application relates to the technical field of lamp tube treatment, in particular to a breaking device and treatment equipment of a mercury-containing fluorescent lamp tube. Background In the recovery of the waste lamp tube, because the waste lamp tube contains some toxic substances such as mercury and the like, the mercury is volatilized into the air after being crushed, so that serious harm is caused after the mercury is inhaled into a human body, and the mercury vapor enters soil or water to cause environmental pollution. The existing crushing device is generally only provided with a crushing structure, and crushed materials after being crushed are discharged for recycling after the lamp tube is crushed. Therefore, the design is that the lamp tube fragments and solid mercury sulfide in the reaction vessel are solidified by using concrete to form a solidified block, and the reaction vessel is integrally packaged and buried, so that the reaction vessel has better protection effect than a lamp tube treatment device with a crushing function, but the safety is insufficient. In the prior art, the broken fluorescent tube is solidified by using concrete, sulfur powder and other similar solidifying agents, so that the mercury gas in the mercury-containing fluorescent tube is treated. For example, CN202210633291.2 discloses a treatment method of mercury-containing lamp tube, firstly, putting the mercury-containing lamp tube to be treated and mercury absorbent into a reaction container, sealing, turning over the reaction container to make the mercury-containing lamp tube to be treated roll in the reaction container, repeatedly striking to make it break and release mercury vapor, combining the mercury vapor with mercury absorbent to form precipitate, making the whole reaction process be implemented in the sealed reaction container, further, opening sealing cover, pouring solidifying material from material pouring opening, solidifying lamp tube fragments and solid mercury sulfide in the reaction container by concrete to form solidifying block, and making the reaction container be integrally packaged and buried. For example, the Chinese patent document CN202310503655.X discloses a high-efficiency combination device for breaking mercury-containing lamp tubes, and the combination device is also converged with the technical path of the technical scheme. The existing technical scheme realizes the treatment of the medium mercury waste gas of the mercury-containing fluorescent tube, but has two problems, namely, the high overflow risk of the mercury waste gas still exists in the treatment process, for example, after the fluorescent tube is broken in the technical scheme disclosed by CN202210633291.2, the curing agent is put into the material inlet of the treatment device after the material inlet of the treatment device is opened. In addition, the prior art scheme can not recycle other materials in the fluorescent tube or has great recycling difficulty, such as metal, plastic and the like, which causes resource waste. Disclosure of utility model The embodiment of the application provides a breaking device of a mercury-containing fluorescent tube, which improves the reliability of the breaking device of the mercury-containing fluorescent tube on mercury-containing waste gas treatment and improves the resource recycling rate so as to at least partially solve the technical problems.
