Description
Technical Field
The invention belongs to the technical field of coal gas storage engineering, and relates to a single-section type membrane sealing type coal gas tank transformed from a polygonal coal gas tank.
Background
The polygonal gas holder (i.e. man-type gas holder) is a thin oil sealed gas holder, the cylinder body has the appearance characteristic of a regular polygon by adopting a piston sealing method of thin oil and a steel sliding plate, and after the man-type gas holder is introduced from japan in 1979 of Bao Steel for storing coke oven gas, the polygonal gas holder is rapidly developed in China and is generally adopted by various steel enterprises. However, due to the inherent low piston speed characteristic and insufficient installation accuracy of the polygonal gas holder, the operation of the polygonal gas holder has the problems of piston inclination, piston guide wheel blockage, large oil drainage amount and the like. In addition, the maximum running speed of the piston can not meet the requirement of a whole-plant gas pipe network on the online running of the gas tank, and the market requirement of transforming the polygonal gas tank into the single-section rubber membrane sealing type gas tank is met.
Compared with a polygonal gas holder, the single-section rubber membrane sealed gas holder has the advantages of stable gas storage pressure, simple structure, high piston running speed (high throughput), no oil-containing waste water discharge and the like, is limited by the manufacturing length of the rubber sealing membrane (the maximum height of domestic manufacture is about 25m), the height-diameter ratio of a newly-built single-section membrane sealed gas holder is generally designed to be about 1:1, the piston and the cylinder are both circular, and the maximum holder capacity of the currently-built single-section membrane sealed gas holder in China is within 15 ten thousand m 3. Taking a built 13.5-ten-thousand-m 3 one-section type membrane sealing gas tank as an example, the diameter of the inner wall of the side plate is about 62m, the number of the upright posts is 32, the total height of the side plate is about 70m, the stroke of the piston is about 45m, and the height-diameter ratio (the total height/diameter of the side plate) is about 1.13.

Gas holder horizontal cross-section curb plate length of side 7m, curb plate height: 98.56m, the height-diameter ratio of the gas holder 98.56/53.629 is 1.84, so that the technical problem of how to economically and reasonably transform the existing 20 ten thousand m3 polygonal gas holder into a rubber film sealing type gas holder under the condition of the manufacturing length of the existing rubber sealing film is urgent.
The related technology of reforming a polygonal gas tank into a membrane sealing type gas tank in the prior art usually modifies a cylinder into a circular shape and reforms the cylinder in a mode of sacrificing the sectional area of the cylinder, the use economy of the gas tank can be greatly reduced due to the sacrifice of the sectional area, and the sectional area of the gas tank is more restricted in consideration of the fact that spaces for installation, welding, corrosion prevention and inspection are reserved in the cylinder.
