Description
Technical Field
The invention belongs to the technical field of mechanical engineering, and particularly relates to an online detection device for abrasion of sealing rubber of a gas chamber.
Background
The high-efficiency utilization of energy of large-scale modern iron and steel enterprises marks the modernization level of the enterprises, and the high-efficiency utilization of byproduct gas is not only the energy demand in the production process of the enterprises, but also the requirement of environmental protection. The gas cabinet is used as buffering and pressure stabilizing equipment of a whole plant gas pipe network, and has the main functions of buffering the fluctuation between the gas generation amount and the gas consumption amount and stabilizing the pressure of the whole plant gas pipe network. When the gas generation amount is larger than the using amount, the pressure of the pipe network is correspondingly increased, and redundant gas automatically enters a gas cabinet to prevent the pressure of the pipe network from being continuously increased; when the gas generation amount is less than the using amount, the pressure of the pipe network is correspondingly reduced, the shortage of gas is automatically supplemented by the gas tank, and the pressure of the pipe network is prevented from being continuously reduced. The shutdown of the gas tank can increase the gas emission amount and cause energy waste; secondly, the safe operation of the gas system is affected.
The Chinese patent No. CN02221732.0 "gas cabinet sealing device", has disclosed a kind of cylindrical gas cabinet sealing device; the patent No. CN200810069664.8 discloses a force applying mechanism for a sealing device of a gas chamber. The name of the method is as follows: the patent refers to the field of 'gas-holder sealing devices, or systems thereof'. A piston oil groove sealing device composed of a plurality of layers of sealing rubber, canvas 12 at the bottom of a pocket and other parts is arranged in a piston oil groove between a piston box beam 1 and a side plate 8 of a gas chamber, and is hung on the piston box beam 1 by a hanging mechanism 6; by the hold-down mechanism that depression bar 14, company board 9, lever 3, wire rope 5, counter weight 2 and wire rope card 4 are constituteed, make sealing rubber laminate on 8 inner walls of curb plate through the backup pad that is connected with company board 9 on the piston box roof beam 1, this sealing rubber includes: 10-1 parts of rubber sealing strips, 10-2 parts of first rubber sealing strips, 10-3 parts of second rubber sealing strips, 10-4 parts of third rubber sealing strips and 10-5 parts of fourth rubber sealing strips; one end of a canvas 12 is arranged between two sealing rubbers through a rubber clamping device 13, and the other end of the canvas is arranged on a piston box beam 1, so that the piston box beam 1 and a piston oil groove sealing device are in flexible connection, the sealing rubber is ensured to be always tightly attached to a side plate 8 under the action of the piston oil groove sealing device and a pressing mechanism, and the sealing oil 7 in the piston oil groove is ensured to have a certain oil seal height to seal gas 16. The gas holder sealing device is formed by connecting two groups of sealing rubbers with 50 mm-height cavities in the middles, which are vertically arranged along the axis direction of the gas holder, into a whole through a screw rod by a metal clamping mechanism, so that the phenomenon that the leakage amount of sealing oil 7 is large due to the deformation of a side plate 8 and other factors is avoided, the sufficient height of the oil level of a piston oil groove is kept, the gas holder is prevented from leaking gas 16 in the operation process, and the safe operation of the gas holder is ensured.
Because the sealing rubber thickness that allows wearing and tearing only has 20mm among the piston oil groove sealing device, surface floating rust clearance is incomplete when curb plate 8 installs and various reasons such as unevenness are polished to the welding seam, all can accelerate sealing rubber's wearing and tearing, shorten its life, the 20mm sealing rubber that allows wearing and tearing among the sealing device probably wears out completely, clamping mechanism's among the piston oil groove sealing device metalwork and 8 inner wall frictions of coal gas cabinet curb plate, probably lead to gas cabinet overall structure's damage, shorten the life of gas cabinet from this. Because the depth of the sealing oil 7 of the piston oil groove is about 1 meter 6, personnel cannot enter the piston oil groove to detect the abrasion loss of the sealing rubber when the gas tank operates.
In the prior art, a sealing rubber abrasion detection hole 15 with the diameter of 300mm is formed in the second side plate 8 of the gas holder, the gas holder is plugged by a cover plate during operation, a gland is pressed tightly, after a piston falls to the bottom, the whole sealing rubber is positioned in the middle of the sealing rubber abrasion detection hole 15, the upper part of the sealing rubber is provided with piston oil groove sealing oil 7, and the lower part of the sealing rubber is provided with gas 16. During detection, the gas tank is stopped, and the piston falls to the bottom. The first step is to replace the gas 16 at the lower part of the piston with nitrogen until the content of carbon monoxide is lower than 24ppm (one day is needed for replacing the gas 16 with nitrogen); the second step is that the sealing oil 7 of the piston oil groove is completely unloaded to the bottom oil groove by manpower, then the gland and the cover plate are dismantled, and the abrasion of the sealing rubber can be detected after sundries mixed at the position of the clamping wood 11 of the sealing device are cleaned (the process needs one day). And thirdly, after detection is finished, installing a detection hole cover plate and a gland, and conveying the sealing oil 7 to the piston oil groove from the bottom oil groove by using a pump so as to enable the oil level to reach the design standard (one day). And fourthly, replacing air at the lower part of the piston with nitrogen, and when the oxygen content is detected to be lower than 1%, sending the coal gas 16 into a coal gas cabinet for putting into production (needing one day). Therefore, the whole sealing rubber abrasion detection process can be finished only by stopping the production of the gas tank for at least four days.
The sealing rubber abrasion detection hole 15 is arranged on the side plate 8, and is plugged by a cover plate during operation, and a gland is pressed tightly. Due to poor construction and installation or other reasons, the arrangement defects of the sealing rubber abrasion detection hole 15 are that firstly, the phenomenon of oil leakage often occurs, which not only causes the waste of the sealing oil 7, but also pollutes the environment; secondly, when the safety is serious, gas leaks out of the gas cabinet, so that the safe and stable operation of the gas cabinet is influenced, and the life safety of production and operation personnel is greatly threatened.
The sealing rubber abrasion detection hole 15 is formed in the side plate 8, and is plugged by a cover plate during operation, and a gland is pressed tightly. When the production stoppage is detected, the maintenance personnel need to firstly lift the sealing oil 7 of the piston oil groove into the bottom oil groove, then remove the detection hole gland and the cover plate, and the cleaning is mixed with the sundries at the position of the sealing device clamp wood 11, so that the abrasion loss of the sealing rubber can be detected, and the maintenance cost of enterprises is increased.
When the sealing rubber abrasion detection hole 15 is used for detection, sundries mixed in the position of the clamping wood 11 of the sealing device need to be manually cleaned, the detection result error is large due to factors such as whether the sundries at the detection point are cleaned or not, whether the detection method is accurate or not, and the like, and the subsequent analysis and judgment on the abrasion condition of the sealing rubber are influenced.
Must stop production when carrying out the sealing rubber wearing and tearing detection through sealing rubber wearing and tearing inspection hole 15 and go on, can't realize on-line measuring, cause the energy extravagant on the one hand, on the other hand has very big potential safety hazard, in case the sealing rubber wearing and tearing do not in time discover totally, the gas chamber just can't the safety and stability operation even emergence accident.
Therefore, the prior art for checking the abrasion condition of the sealing rubber of the gas tank is very complicated, and has a great safety risk.
