Description

Acetylene generator

Technical Field

The utility model relates to an acetylene generator field especially relates to an acetylene generator.

Background

At present, the acetylene preparation method by calcium carbide mainly adopts a wet acetylene process at home and abroad, namely, large calcium carbide blocks are put into a generator filled with water, and reaction heat is taken away by utilizing the temperature rise of the water, so a large amount of water is consumed in the reaction process, and a large amount of calcium carbide slurry needs to be treated. According to incomplete statistics, the discharged carbide slag reaches 1000 ten thousand tons all the year round, and the carbide slurry is 9000 ten thousand tons. If the calcium carbide slurry is treated, filter-pressing sedimentation equipment is additionally constructed for separating solid from liquid, and then clear liquid is recycled; then, the carbide slag filter cake can be comprehensively utilized through drying treatment, and large one-time investment cost and long-term operation and maintenance cost are needed.

Meanwhile, calcium carbide added in the wet acetylene process cannot be continuously fed, and slag discharge cannot be continuously carried out. Therefore, once the calcium carbide is added into the reactor, the reaction can not be stopped immediately, and the reactor can be stopped after the calcium carbide is fed and completely reacts, so that the waste and potential safety hazards caused when the overhaul or the follow-up production is stopped are caused. Negative pressure is easily formed during slag discharge to cause potential safety hazard. The large calcium carbide blocks can be wrapped in water, so that the calcium carbide cannot react completely, and waste is caused.

With the continuous enhancement of the environmental protection requirement, the pollution of the wet acetylene to the environment is increasingly paid attention by the countries and manufacturers, so some manufacturers begin to adopt the dry acetylene process for production. Compared with the wet method, the water consumption of the dry method process is greatly reduced, and the generated calcium hydroxide waste residue is dry powder and is very easy to treat.

Aiming at unreacted calcium carbide separated from the existing dry-method acetylene carbide slag, silicon iron which can be recycled, calcium carbide dust generated in the links of calcium carbide crushing and the like, the acetylene generator with an improved structure is necessary to overcome the defects in the prior art.
