Embodiment Construction

[0009] The present invention will be further described below in conjunction with embodiment.

[0010] see figure 1 , the slurry acetylene recovery device is composed of a stripper 1, an acetylene cooler 3, a steam-water separator 4, and a concentration tank 5. The upper part of the stripper 1 is connected with the acetylene flash steam inlet of the acetylene cooler 3 through a pipeline 2, and the acetylene The lower part of the cooler 3 is connected with the steam-water separator 4 through the pipeline 2, and the outlet of the slurry feeding pipe 6 at the bottom of the stripping tower 1 is directly connected with the concentration tank 5 and submerged under the liquid surface of the concentration tank 5; It should be ensured that the stripper 1 acts as a liquid seal. In the figure, there are two concentrating pools 5.

[0011] The operating process of the present invention is briefly described as follows:

[0012] The slurry produced by the wet acetylene generator is forced...

Abstract

The invention relates to a wet type acetylene generating device in a polyvinyl chloride production process, and in particular relates to a slurry acetylene recycling device. The slurry acetylene recycling device comprises a stripping tower, an acetylene cooling device, a steam water separator and a concentrating tank, wherein the upper part of the stripping tower is connected with the acetylene cooling device by virtue of a pipeline, the lower part of the acetylene cooling device is connected with the steam water separator by virtue of the pipeline, and the outlet of a slurry discharging pipe at the bottom of the stripping tower is directly connected with the concentrating tank and is submerged under liquid level of the concentrating tank. According to the slurry acetylene recycling device disclosed by the invention, a liquid seal tank in the original device is eliminated, the slurry discharging pipe of the stripping tower is directly inserted under the liquid level of the concentrating tank, and liquid seal is guaranteed, thus sealing requirement of the stripping tower is realized, and a phenomenon that slurry blocks the original liquid seal tank is avoided; and the slurry acetylene recycling device disclosed by the invention has the characteristics of being obvious in economic benefit, easy and simple in operation and excellent in safety performance.

Description

technical field [0001] The invention relates to a wet acetylene generating device in the production process of polyvinyl chloride, in particular to a slurry acetylene recovery device. Background technique [0002] Calcium carbide is an important raw material for calcium carbide PVC enterprises, and a large amount of acetylene gas remains in the calcium carbide slurry produced by its hydrolysis. Letting the volatilization and loss of residual acetylene in the calcium carbide slurry not only cause a great waste of resources, but also pose a great safety hazard due to the flammable and explosive characteristics of acetylene gas. At present, the known method for recovering acetylene from the slurry is to safely recover and utilize the acetylene gas remaining in the calcium carbide slurry through vacuum, stripping, flash evaporation and other process steps. Specifically, the acetylene in the liquid dissolved and unreacted calcium carbide is recovered through the slurry acety...
