Technical Field

The invention relates to the field of dry acetylene generating systems, in particular to a dry acetylene generating closed system.

Background

The dry acetylene generation process comprises the following steps: the calcium carbide produced in the industrialized production is in a disc shape with the diameter of about 1 meter, and calcium carbide fine materials with the diameter less than 3mm are formed after multi-stage crushing. The fine calcium carbide material meeting the requirement of the granularity is conveyed into a dry acetylene generator and reacts with a certain proportion of water to generate acetylene gas. The calcium carbide slag is formed after the reaction of the calcium carbide, and is a high-quality cement production raw material.

On the one hand, the waterway system of the acetylene workshop dry-method acetylene generating device is in external circulation, so that water resource waste is caused. On the other hand, the washing cooling tower realizes cooling and washing of acetylene gas; the bottom slag slurry of the washing cooling tower is discharged to a concentration tank pipeline for frequent deposition and blockage, the washing slag slurry water of the generator can be discharged only by pouring, the trench slag slurry needs to be cleaned every day, the field environment is poor, and the labor intensity is increased; and waste water resources.

Disclosure of Invention

To solve the above problems, the present invention discloses a dry acetylene generating closed system.

In order to achieve the above purpose, the invention provides the following technical scheme:

a dry acetylene generating closed system; comprises a generator, a washing cooling tower and a concentration tank; the generator is connected with a generator water inlet pipeline, a generator material inlet pipeline, an ethylene gas outlet pipeline and a slag discharge pipeline; the ethylene gas outlet pipeline is connected with a washing cooling tower; the washing cooling tower is connected with a purification air outlet pipeline, a washing water inlet pipeline and a washing water outlet pipeline; the slag discharge pipeline is connected with the concentration tank; the concentration tank is connected with a filter press; a liquid outlet of the filter press is connected with a washing water inlet pipeline; the washing water outlet pipeline is connected with the generator water inlet pipeline.
