Abstract
The utility model relates to a wet type acetylene generator in production of polyvinyl chloride, in particular to a device for recovering acetylene from slurry. The device comprises a stripper, an acetylene cooler, a steam-water separator and concentrating tanks. The upper portion of the stripper is connected with the acetylene cooler through a pipe, the lower portion of the acetylene cooler is connected with the steam-water separator through a pipe, and slurry discharge pipes at the bottom of the stripper are connected with the concentrating tanks directly and then extend into liquid levels of the concentrating tanks. A liquid seal tank of an existing device is omitted, the slurry discharge pipes of the stripper are directly inserted into the liquid levels of the concentrating tanks, and a liquid seal effect is guaranteed, so that sealing requirements of the stripper are met, and the problem that the existing liquid seal tank is blocked by slurry is avoided. The device for recovering acetylene from slurry has the advantages of remarkable economic benefit, simplicity and convenience in operation and excellent safety performance.
Description
Technical field
The utility model relates to wet type acetylene generator in the Production of PVC operation, specifically is a kind of slag slurry acetylene.
Background technology
Calcium carbide is the important source material of calcium carbide process PVC enterprise, remaining a large amount of acetylene gas in the carbide slag slurries that its hydrolysis produces.The volatilization of letting alone remaining acetylene in the carbide slag slurries is run off, and not only causes the great wasting of resources, simultaneously because also there is very big potential safety hazard in inflammable, the explosive characteristic of acetylene gas.At present, known slag slurry acetylene recovery method is through process procedures such as vacuum, stripping, flash distillations, and the acetylene gas safety that remains in the carbide slag slurries is recycled.Specifically; Be through the acetylene of slag slurry acetylene stripper in dissolving of vacuum state recover liquid and unreacted calcium carbide; The acetylene gas that reclaims is delivered to Acetylene Gas Holder, and the slag slurry that reclaims behind the acetylene gets in the liquid seal can that band stirs facility from stripping tower, through the potential difference overflow to concentration basin.But milk of lime content is very high in the slag pulp waste water; Because milk of lime is a kind of soup compound, runs up to the obstruction that to a certain degree can cause liquid seal can, must interrupt the operation that slag slurry acetylene reclaims technology for this reason; So that replace, open and inspect etc.; Both caused the acetylene waste, safety does not have guarantee again, is that still unsolved at present slag slurry acetylene reclaims the technology drawback.
The utility model content
The utility model is intended to solve above-mentioned liquid seal can blocking problem, and provides a kind of liquid seal can of can avoiding to stop up, and can give full play to the slag slurry acetylene of liquid seal can function again.
The technical scheme that the said problem that solves the utility model adopts is:
A kind of slag slurry acetylene; Comprise stripping tower, acetylene water cooler, steam separator, concentration basin; Stripping tower top is connected with the acetylene water cooler through pipeline; Acetylene water cooler bottom is connected with steam separator through pipeline, and the slag slurry tremie pipe outlet of said stripping tower bottom directly is connected with concentration basin and slips into below the concentration basin liquid level.
Compared with prior art; The beneficial effect of the utility model is: cancelled the liquid seal can in original device; Stripping tower slag slurry tremie pipe is directly inserted below the concentration basin liquid level and guarantees fluid-tight, both realized the stripping tower seal request, avoided the slag slurry to stop up former liquid seal can phenomenon again.Have remarkable in economical benefits, easy and simple to handle, safety performance excellent characteristics.
Description of drawings
Fig. 1 is the utility model example structure synoptic diagram.
Among the figure: the 1-stripping tower; The 2-pipeline; 3-acetylene water cooler; The 4-gas-liquid separator; The 5-concentration basin; 6-slag slurry tremie pipe.
Embodiment
Below in conjunction with embodiment the utility model is described further.
Referring to Fig. 1; Slag slurry acetylene is made up of stripping tower 1, acetylene water cooler 3, steam separator 4, concentration basin 5; The top of stripping tower 1 is connected with the acetylene gas flash steam import of acetylene water cooler 3 through pipeline 2; Acetylene water cooler 3 bottoms are connected with steam separator 4 through pipeline 2, and the outlet of the slag slurry tremie pipe 6 of stripping tower 1 bottom directly is connected with concentration basin 5 and slips under the liquid level of concentration basin 5; The degree of depth that slips into liquid level should guarantee stripping tower 1 is played the fluid-tight effect.Concentration basin 5 is provided with two among the figure.
The operational process of the utility model is summarized as follows:
The slag slurry that the wet type carbide-feed generator produces is forced the slag slurry is squeezed into stripping tower 1 through the slag stock pump; Under vacuum state; Dissolving and be adsorbed on the acetylene gas in the slip and puts forward the acetylene gas flash steam, behind 3 coolings of acetylene water cooler, steam separator 4; With water ring vacuum pump acetylene gas is reclaimed, and the carbide slag mud behind the stripping directly gets into concentration basin 5 through slag slurry tremie pipe 6.Because it is enough dark under the liquid level that the outlet of slag slurry tremie pipe 6 is opened and slipped in the concentration basin 5, therefore, liquid level can play the fluid-tight effect for stripping tower 1 in the concentration basin 5, has prevented the volatilization of remaining acetylene.When the degree of depth of concentration basin 5 was five meters, the degree of depth that slag slurry tremie pipe 6 gos deep into concentration basin was 1.2 meters.
Claims (2)
1. a slag is starched acetylene; Comprise stripping tower, acetylene water cooler, steam separator, concentration basin; Stripping tower top is connected with the acetylene water cooler through pipeline; Acetylene water cooler bottom is connected with steam separator through pipeline, it is characterized in that, the slag slurry tremie pipe outlet of said stripping tower bottom directly is connected with concentration basin and slips into below the concentration basin liquid level.
2. slag slurry acetylene according to claim 1, it is characterized in that: said concentration basin is made as two.
