Description

Technical Field

[0001] The utility model relates to the technical field of feeding materials for acetylene production, in particular to a dissolved acetylene feeding device with a material storage structure. Background Art

[0002] The industrial methods for producing acetylene are divided into the hydrolysis of calcium carbide method, the partial oxidation of methane method, and the plasma cracking method. The hydrolysis of calcium carbide method is to react calcium carbide with water, but instead of putting calcium carbide into water, water is added to calcium carbide. Before the reaction, the calcium carbide is crushed, and then water is sprayed into the calcium carbide in the form of mist to react with the calcium carbide, so that the water content of the produced Ca(OH)2 is low, which reduces the cost of treating the residue and allows the produced Ca(OH)2 to be directly recovered.

[0003] This reaction process requires the continuous addition of calcium carbide. Since acetylene gas is toxic, it is very dangerous to manually open the reaction tank to add calcium carbide. When adding calcium carbide to the reaction tank, it is necessary to open the filling cover and add the material from the top. First, the material can be added all at once, but this method easily causes the calcium carbide to accumulate at the bottom of the tank and cannot fully contact with water, resulting in a slow reaction speed; or calcium carbide can be added in batches in the tank, but this method easily causes gas leakage. For this reason, we propose a dissolved acetylene feeding device with a storage structure. Utility Model Content

When the first driving motor 14 rotates, the first spiral shaft 7 is driven to rotate, and the calcium carbide powder flowing into the feeding channel 33 is transported upward along the conveying cylinder 2.

[0034] like Figure 1 and Figure 2 As shown, the other end of the conveying cylinder 2 is provided with a discharge channel 8 at the bottom, and a rectangular channel 21 is provided at the bottom to connect with the top. A rectangular opening 5 is provided on the side of the rectangular channel 21 close to the conveying cylinder 2, and a sealing plate 22 is movably inserted in the rectangular opening 5.

[0039] Finally, the calcium carbide powder reacts with water to generate calcium hydroxide and acetylene gas.
