Washing pipe system of dry-method acetylene generator

Abstract

The invention provides a washing pipe system of a dry-method acetylene generator and relates to the technical field of chemical equipment. The washing water inner circulation system of the dry-methodacetylene generator comprises the dry-method acetylene generator, a gas-phase scraper, a washing cooling tower, a residue water recycle pump, a gas pipe and a washing water pipe; one end of the gas-phase scraper is connected with the dry-method acetylene generator, and the other end of the gas-phase scraper is connected to the washing cooling tower through the gas pipe; one end of the residue water recycle pump is connected with the washing cooling tower through the washing water pipe, and the other end of the residue water recycle pump is connected with the a dry-method acetylene generator water injection spray nozzle and the gas-phase scraper. According to the washing pipe system of the dry-method acetylene generator, the washing water pipe is arranged to be the inner circulation system,then washing water of the generator is directly recycled, the problems of acetylene gas loss and environmental pollution in the prior art are solved, and the washing pipe system has the advantages ofenvironmental protection and energy consumption reduction.

Description

technical field [0001] The invention relates to the technical field of chemical equipment, in particular to a washing pipeline system of a dry-process acetylene generator. Background technique [0002] At present, the production method of acetylene, the basic chemical raw material in China, is mainly the production method of calcium carbide acetylene. The traditional wet acetylene production process is to put a large piece of calcium carbide into a generator filled with water, and use the temperature rise of the water to take away the heat of reaction. Therefore, a large amount of water is consumed in the reaction process, and a large amount of calcium carbide mortar is required. deal with. According to incomplete statistics, as many as 10 million tons of calcium carbide slag and 90 million tons of calcium carbide mortar are discharged in the global wet acetylene production process every year. How to deal with these calcium carbide mud has become a very troublesome problem...

Problems solved by technology

Since the existing washing water pipeline design for washing acetylene often adopts the external circulation process, after the slurry water is discharged from the washing tower, the C dissolved in the water 2 h 2 、H 2 S.PH 3 , AsH 3 The gas will escape into the atmosphere naturally, which will cause the loss of acetylene gas and certain environmental problems.

[0004] Therefore, research and development of a dry-process acetylene generator washing pipeline device, transform the existing acetylene generator washing water pipeline, change the original washing water pipeline from the external circulation to the internal circulation system, and then directly reuse the generator washing water , to alleviate the loss of acetylene gas and environmental pollution in the prior art, and to achieve the purpose of protecting the environment and reducing energy consumption has become very necessary and urgent
