Abstract
The utility model relates to equipment for filtering and separating oil slurry in a catalytic cracking fractionating tower. The equipment consists of a fractionating tower body, a herringbone baffle plate, a clapboard, a filtering net and a pump, wherein the herringbone baffle plat is positioned on the lower part in the fractionating tower body and separates the lower part of the fractionating tower body into a space A; the clapboard is positioned in the space A and separates the space A into a sealed filtering and separating space; the filtering net is positioned in the middle of the filtering and separating space and divides the filtering and separating space into a space B and a space C; and the space A and the space B are communicated through a pump outside the fractionating tower body. The equipment for filtering and separating the oil slurry in the catalytic cracking fractionating tower is reasonable in design and simple in structure. The solid particle-containing oil slurry is directly filtered in the fractionating tower, and a filtering effect better than that of filtration outside the fractionating tower can be achieved because the viscosity of the oil slurry is low.
Description
Technical field
The utility model relates to slurry oil filtering separation device in a kind of catalytic cracking fractionating tower.
Background technology
Catalytic cracking is to improve the level of crude oil processing in the refinery, produces gasoline, diesel oil and the important heavy oil lighting technological process of liquefied gas.Along with raw oil constantly becomes heavy, in order to improve unit capacity, to increase yield of light oil, the refinery generally takes to reduce slurry oil recycle ratio, the measure of getting rid of the part slurry oil outward.Externally extracting oil can also be as the raw material of producing multiple Chemicals such as raw material of wood-charcoal material, carbon black, needle coke, thomel except can be used as oil fuel, atmospheric and vacuum distillation and delayed coking raw material, and the comprehensive utilization slurry oil has good economic benefits.(yet general content has limited its comprehensive utilization 2～6g/L) to contained solid particulate in the slurry oil, therefore must remove the solid particulate in the slurry oil.
The industry separation method that uses except that solid particulate in the slurry oil that gets on mainly contains natural sedimentation, auxiliary agent settling process, filtration method, electrostatic separation method and centrifugal separation etc.; Wherein filtration method has advantages such as equipment is simple, less investment, dependable performance; Be widely used in Petrochemical Enterprises, and be main with the form that the slurry oil strainer is set outside separation column.
For the outer slurry oil strainer that is provided with of separation column; Receive the restriction of pipeline insulating efficiency; All can there be temperature drop in various degree in slurry oil from separation column to the slurry oil strainer, and slurry oil has the full-bodied characteristics of low temperature, so the reduction of temperature will certainly influence the separating effect of slurry oil strainer.
The utility model content
The purpose of the utility model provides slurry oil filtering separation device in a kind of catalytic cracking fractionating tower, utilizes the solids content in the characteristic effective elimination slurry oil that the slurry oil temperature is high in the separation column, viscosity is low.
The slurry oil filtering separation device is made up of fractionation tower body, herringbone baffle plate, dividing plate, filter screen and pump in the described catalytic cracking fractionating tower of the utility model; The herringbone baffle plate is positioned at fractionation tower body bottom; By the herringbone baffle plate lower section in the fractionation tower body is separated out a space A; Dividing plate is arranged in space A; Space A is separated out an airtight filtering separation space again, and filter screen is positioned in the middle of the filtering separation spatial, and the filtering separation spatial is slit into space B and space C; Space A and space B are communicated with through the external pump of separation column.
The slurry oil that gets off from the herringbone baffle plate gets into space A, extracts out through the external pump of separation column and squeezes into space B; Slurry oil passes the filter screen between space B and the space C, and the solid of slurry oil is stayed space B; The slurry oil that entering space C removes solid particulate relies on pressure to leave separation column to product storage tank as product.
The slurry oil filtering separation device is reasonable in design, simple in structure in the described catalytic cracking fractionating tower of the utility model, contains the solid particulate slurry oil and directly in separation column, filters, because its viscosity is low, can obtain than the better filter effect of the outer filtration of separation column.
