Online catalytic slurry oil filter tank

Abstract

An online catalytic slurry oil filter tank relates to the technical field of petroleum production equipment. A blowdown device, a filter bin, a standby tank and a decontamination device are arranged in a tank body, the filter bin is arranged on the blowdown device, a filter element is arranged in the filter bin, the decontamination device is arranged on the filter element, and the decontaminationdevice consists of a dirt scraping device, a first connecting rod, a third connecting rod and a transmission device. When the transmission device drives the dirt scraping device to move up and down, the dirt scraping device scrapes dirt in the filter element into a second dirt guide pipe, filtered slurry oil flows back into the filter element for back washing through the pressure intensity difference, blocked dirt in the filter element is discharged through the blowdown device, the dirt scraping device is pulled out of the filter element, the standby tank is pushed downwards and ejects out thefilter bin for replacing the filter bin, and thus the purposes of online filtering of the catalytic slurry oil and replacement of the filter element are achieved. The online catalytic slurry oil filter device is reasonable and practical in structure, can filter catalytic slurry oil more quickly, and the catalytic slurry oil treatment efficiency of workers is improved.

[0002] As we all know, catalytic oil slurry is a product of petroleum technology. The treatment of catalytic oil slurry is a difficult problem in the petroleum field. Natural precipitation in the tank, after precipitation, the catalytic oil slurry is separated in the storage tank, and the oil in the upper layer of the oil slurry in the storage tank can be reused, while the lower layer of the oil slurry in the storage tank can only be used as chemical raw materials. Due to the presence of catalyst particles in the oil slurry, the utilization value of such oil slurry is very small. If the catalytic particles in the oil slurry cannot be filtered, the oil slurry will either be burned as waste or precipitated through the storage tank However, burning the oil slurry as waste will not only cause damage to the sintering furnace, but also cause serious pollution to the atmosphere due to the oil fume generated when burning the oil slurry. Therefore, the catalytic oil slurry can only be stored in a tank for sedimentation Temporary storage, and as more and more oil slurry is discharged from the refinery every day, more and more oil tanks need to be stored, and the occupied space is also increasing

[0003] The difficulty in the treatment of catalytic oil slurry is to filter the catalyst particles in the catalytic oil slurry, but when the catalytic oil slurry is cooled, the catalytic oil slurry will become asphalt, so that the catalytic oil slurry cannot be filtered, and on the oil pipeline For the filtration of catalytic oil slurry, neither foreign nor domestic equipment has practical value at present. Because the temperature of catalytic oil slurry is too high, it is difficult for ordinary filters to withstand such a high temperature. At the same time, oil is highly corrosive and explosive. As a result, the usual filter screen is easily damaged, and there will be safety hazards such as explosions if you do not pay attention. In addition, the pressure in the oil pipeline is usually not fixed, and the viscosity of the oil slurry itself will cause the filter screen to occur for a long time. The phenomenon of clogging, the general catalytic oil slurry filter is blocked in one to two weeks and cannot be used, and it needs to be replaced with a new filter element before it can be used again, and the cost of replacing and cleaning the filter element is very high, which greatly increases The production cost is reduced, so that the enterprise can only give up the filtration of catalytic oil slurry
