[0024] Example

[0025] like figure 1 As shown in the figure, the combined screening and combing dry acetylene generating unit of the present invention includes a screening generator, an isolation bin, a combing generator, a fine blending machine 19 and a slag extractor 20 which are sequentially connected by pipelines; The isolation bin is also connected with the precision dispensing machine 19 through a pipeline.

[0026] In order to make the calcium carbide reacted in the screening generator enter the isolation bin smoothly, a screw conveyor 10 is provided between the screening generator and the isolation bin, and below the feed port of the screw conveyor A first sampling port 11 is provided, and its sampling port can collect the granularity of calcium carbide after the reaction of the sieving generator. After analysis, the reducer of the sieving generator and the water inflow can be adjusted according to the results, so that the calcium carbide can be The sieving type gen...

Abstract

The invention relates to a screening-combing combined type dry method acetylene generating unit, which solves the problems that in the prior art, as calcium carbide and ash powder cannot be separated quickly, packaging reaction is caused, and the production efficiency and the production continuity are affected. The screening-combing combined type dry method acetylene generating unit comprise a screening generator, a separation bin, a combing generator, a refined preparation machine and a deslagging machine which are connected through a pipeline sequentially, wherein the separation bin is also connected with the refined preparation machine through a pipeline. The screening-combing combined type dry method acetylene generating unit has a simple and reasonable structure, the screening generator can be used for carrying out primary reaction on the calcium carbide, and the combing generator can enable the smaller calcium carbide subjected to reaction through the screening generator to react, so that the calcium carbide can be fully reacted, and the reaction rate of the calcium carbide is improved; and the produced waste residues can be processed in a centralized way, so that pollution to environment is avoided.

Description

technical field [0001] The invention relates to an acetylene generating device, in particular to a screening and carding combined dry-process acetylene generating unit. Background technique [0002] At present, there are mainly two methods for the preparation of acetylene: dry method and wet method. The production of 1 ton of PVC by wet process produces 1.8 tons of calcium carbide slag, with a water content of 1.2 tons. To remove 1 ton of water, 150 kg of standard coal is required, and the unit price of standard coal is 450 yuan / ton. The processing fee of PVC carbide slag is 85 yuan, and the calcium carbide slag produced by the dry process is used to produce cement without drying, and the annual production of 100,000 tons of PVC saves 8.5 million yuan in cost. [0003] When preparing acetylene by wet method, because calcium carbide is slightly soluble in water, a large amount of water resources are needed, raw materials are wasted, water pollution is formed, environmental p...
