Dry acetylene generation and separation device

Abstract

The invention relates to a dry acetylene generation and separation device. The device comprises an acetylene generator, an acetylene recovery device and an extrusion deslagging device, wherein the acetylene generator is connected with the acetylene recovery device through a pipeline; and the acetylene recovery device is connected with the extrusion deslagging device through the pipeline. The device disclosed by the invention is simple and rational in structure; an agitating shaft in an acetylene generating box has a transmission function and an agitating function; a calcium carbide material completely reacts with water; and the reaction conversion ratio of calcium carbide is high, and the production capacity of the device and the utilization rate of the calcium carbide can be maximally played. An acetylene recovery box extrudes air in carbide slag by utilizing a gravity action and an extrusion action of a thrust shaft, so the probability of discharging acetylene gas along with the carbide slag is effectively avoided. An extrusion deslagging box can discharge the acetylene gas out of the carbide slag twice; and the acetylene gas does not easily leak, and the tail end of the extrusion deslagging box is of a cone shape, so the tightness is good, the effect of continuous sealing can be achieved and the safety is high.

Description

technical field [0001] The invention relates to an acetylene generating device, in particular to a dry type acetylene generating and separating device for the preparation of acetylene. 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,...

AI Technical Summary

Problems solved by technology

[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 pollution is caused, and the yield of acetylene is low. Therefore, dry acetylene preparation is widely used in China

[0004] In the traditional technology, the acetylene generator has a large volume and occupies a large area. The acetylene generator uses a single stirring shaft, which is screw-type, and only has the function of conveying materials. The speed of the stirring shaft is limited. When preparing acetylene, Calcium carbide and water need to be mixed and reacted under the stirring of the stirring shaft, but the stirring shaft of the traditional technology cannot fully stir the materials, reducing the reaction intensity and production intensity of acetylene
