TECHNICAL FIELD
[0001] The utility model relates to the technical field of coal gas holder, concretely to a device for reducing the splashing of sealing oil of a coal gas holder. BACKGROUND
[0002] A coal gas holder is a steel container for storing industrial and domestic coal gas, and there are wet-type coal gas holders and dry-type coal gas holders. The wet-type coal gas holder is a sleeve simple cylindrical structure sealed with water, and the dry-type coal gas holder is a piston structure sealed with thin (dry) oil or rubber film. The thin-oil sealing type coal gas holder is widely used for the recovery and storage of by-product coal gas in a steel enterprise, and an open oil supply system is adopted. In the normal operation process of the thin-oil sealing type coal gas holder, the part where the piston and the holder body move needs to be sealed by a sealing mechanism to seal the coal gas. The sealing oil is stored in the piston oil groove. The circulation of the sealing oil in the normal operation process of the coal gas holder is an important link. The sealing oil continuously leaks from the piston oil groove to the lower part of the piston, falls into the bottom oil groove of the coal gas holder, and then the sealing oil is separated from water in the bottom oil groove. The water is discharged, and the sealing oil is transported to the pre-oil tank on the upper part of the holder body by a screw pump. An overflow hole is opened in the pre-oil tank near the side plate. The sealing oil flows into the holder body of the coal gas holder through the overflow hole, flows down along the inner wall of the side plate, and enters the piston oil groove. This is the normal circulation process of the sealing oil.
[0003] At present, in the normal operation process of the thin-oil sealing type coal gas holder, on the one hand, a large amount of sealing oil splashes (referred to as "first splashing") on the upper part of the piston during the process of overflowing from the pre-oil tank to the piston oil groove, resulting in the loss of thin oil, and it is necessary to regularly add expensive thin oil to the sealing mechanism. On the other hand, the thin oil splashed on the piston plate causes a poor working environment on the upper part of the piston, which is not conducive to the normal inspection and maintenance work of the operating personnel, and is easy to cause damage to the piston, increasing the maintenance cost. At the same time, the splashing oil collecting plate arranged on the upper part of the piston collects the splashed sealing oil. This part of the sealing oil will cause secondary splashing due to the unreasonable structure before falling into the piston oil groove. Further research and optimization of the device and method for preventing the splashing of the sealing oil of the sealing coal gas holder have become a problem to be solved. CONTENT OF THE UTILITY MODEL
[0004] The utility model aims at providing a device for reducing the splashing of sealing oil of a coal gas holder to solve the problem of splashing and loss of sealing oil of the coal gas holder in the prior art.
[0005] In order to achieve the above object, the utility model provides the following technical scheme: a device that reduces coal gas tank sealing oil splashing, including coal gas tank body, the coal gas tank body is equipped with the spare oil tank, the spare oil tank is equipped with overflow hole near the coal gas tank body side plate, the coal gas tank body is equipped with the piston in, and the piston oil ditch is formed between the coal gas tank body side plate and the lower part of piston, and the piston oil ditch is used for storing sealing oil, the upper part of piston is equipped with the splashing oil collection board, and the splashing oil collection board adopts the inclination arrangement, and the position near the coal gas tank body side plate is low, and the position far from the coal gas tank body side plate is high.
[0006] Preferably, the upper end of the splashing oil collection board is covered with a screen, and a brush is installed near the position of the splashing oil collection board close to the coal gas tank body side plate.
[0007] Preferably, the splashing oil collection board is located below the spare oil tank, and the screen corresponds to the position of the overflow hole.
[0008] Preferably, the screen is designed with a multi-mesh structure, and the mesh size is not greater than 10 mm.
[0009] Preferably, the sealing oil drops onto the splashing oil collection board through the overflow hole and drips into the piston oil ditch along the brush.
[0010] Preferably, the position of the piston oil ditch corresponds to the position of the upper brush.
[0011] Compared with the prior art, the utility model has the beneficial effects as follows:
[0012] The device that reduces coal gas tank sealing oil splashing sets the splashing oil collection board with an inclination arrangement, sets a screen on the splashing oil collection board, and installs a brush near the position of the splashing oil collection board close to the coal gas tank body side plate. When the sealing oil flows down from the overflow hole, a part of the oil droplets falls on the screen on the splashing oil collection board, which can prevent the first splashing phenomenon. Before the oil droplets flow into the piston oil ditch through the lower collection board of the screen, a brush is installed near the position of the splashing oil collection board close to the coal gas tank body side plate, which tightly adheres to the inner wall of the coal gas tank body side plate and plays a role in guiding the flow of the sealing oil before it flows into the piston oil ditch, thereby avoiding the second splashing of the sealing oil before it falls into the oil ditch, further reducing the loss of sealing oil and environmental pollution. The utility model changes the direction and buffer flow rate of the falling sealing oil, greatly reducing the force of external overflow splashing. BRIEF DESCRIPTION OF DRAWINGS
