Abstract
A filter for high-temperature heavy oil is a spiral propellent scraper-type filter, and mainly comprises a cylinder body, a cone-shaped segment, a filtering screen, a spiral scraper, a transmission shaft, a driving device, a mixing blade, a turbulence ring pipe, a material inlet, a material outlet, a perturbance port, a deslagging port, an oil meter interface and the like, wherein the material inlet is formed above the cylinder body; and the material outlet is formed under the cylinder body. The technical scheme is that materials entering into the filter via the material inlet are filtered from inside to outside by the filtering screen and then flow out of the material outlet; once filtered coke powder reserved on the inner wall of the filtering screen reaches up a certain amount, the pressure drop of the filter is increased, the driving device of the filter is started up and drives the spiral scraper via the transmission shaft to scrape off the filtered coke powder reserved on the inner wall of the filtering screen; and the scraped coke powder drops into the cone-shaped segment of the filter; then a valve at the bottom of the cone-shaped segment is opened, the filtered coke power (containing some oil) is pumped away from the deslagging port by a pump ( that is a screw pump) and sent away. By adopting the filter provided by the utility model, coke cleaning of the filter is on-line operation without needing standby and switching, so that the labor intensity of the operation is low; since the cone-shaped segment is connected with the cylinder body via a flange, the disassembly and the cleaning of the filter are facilitated; the problems in the present filter that the high-temperature part has high cleaning frequency, large operation labor intensity, potential fire hazard during the cleaning and so on are solved; meanwhile, the operation is simple and reliable.
Description
Technical field
The utility model mainly belongs to coke powder, particulate liquid-solid separator in a kind of petrochemical complex, field of metallurgy and the coal chemical technology High Temperature and Heavy Oil, is specifically related to the filtration of coke powder in the High Temperature and Heavy Oil such as the recycle system at the bottom of the separation column of delayed coking unit, furnace charge system, wax slop system.
Background technology
Delayed coking is a heavy oil degree of depth thermally splitting complete processing, is the main technique of present heavy oil upgrading.Delayed coking mainly is heavy oil to be heated to temperature required (about 500 ℃) back rapidly get into coke drum in process furnace; Carry out elevated temperature heat cracking and condensation reaction after suitable temperature, pressure reaches long-time the stop in coke drum; Reaction generates oil gas and coke; Coke remains in the coke drum, and high-temperature oil gas gets into the product that obtains needs after separation column separates.From coke drum rise the coke powder that carries the warm oil gas in separation column by the reflux in tower washing down, coke powder mainly gets at the bottom of the fractionation Tata and in the wax slop oil header.In order to prevent that coke powder from stopping up the recycle system and wax slop system at the bottom of the separation column, the LP normal running of assurance device need in time be taken out the coke powder in the recycle system at the bottom of the separation column and the wax slop system.At present; The recycle system and wax slop system are provided with common blue formula strainer (behaviour one is equipped with) at the bottom of the tower; When in the strainer during coke powder overheap, filter pressure drop increases, and cutting-off valve before and after the strainer is closed; Through artificial filter rinsed coke powder is wherein taken out, the cleaning labour intensity of strainer is bigger.When misoperation caused the pressure surge of coke drum, the coke powder that carries from coke drum increased, and increased the cleaning frequency (one week of device strainer that has cleans to twice) of strainer, had also increased labour intensity simultaneously.And contain coke powder in the operation medium, influence the normal switch of cutting-off valve before and after the strainer, the phenomenon that fits badly often appears in this position valve.In addition; Because this position service temperature higher (usually greater than 320 ℃, the wax slop system temperature reaches 370 ℃), operation medium is heavy oil (naturally o'clock below 250 ℃); Service temperature is higher than the spontaneous ignition temperature of medium; Trip valve before and after during filter rinsed threatens operative employee's safety in case leakage just can cause fire.For this reason, develop very necessity of a kind of novel strainer at this position.
The utility model content
For solve that existing high temperature position strainer cleans that the frequency is high, operation labour intensity is big and cleaning process in possible problems such as fire hazard; The utility model provides a kind of novel screw propulsion scraper type to filter; Both solved the problems referred to above of existing strainer, operation is simple and reliable simultaneously.
The concrete technical scheme that the utility model adopted is following:
The High Temperature and Heavy Oil strainer mainly is made up of cylindrical shell, awl section, filtering net, spiral scraper, transmission shaft, drive unit, stirring blade, flow-disturbing endless tube, material inlet, material outlet, disturbance mouth, slag-drip opening and instrumentation tap etc.Material inlet is arranged on the cylindrical shell top, and material outlet is arranged on the cylindrical shell below, and material gets into strainer from material inlet, filters from inside to outside through filtering net, and the material after the filtration flows out from material outlet, and the coke powder that filters remains in the inwall of filtering net.When coke powder residual on the filtering net reach a certain amount of after, the pressure drop of strainer raises, and starts the drive unit of strainer, drives spiral scraper through transmission shaft, and the coke powder that remains in the filtering net inwall is scraped off.The coke powder that scrapes off is fallen into the awl section of strainer, and then opens the valve of awl section bottom, and the coke powder that filters (containing part oil) is seen off after slag-drip opening is extracted out with pump (spiral pump).
Described filtering net is arranged on filter interior, all links to each other with strut member through bolt up and down, and filtering net can be wedge shape silk screen or annular filter cylinder, has slotted hole or circular hole on the annular filter cylinder, and the circular hole size is between Φ 5 to Φ 15.
Described spiral scraper is fixed on the rotation axis, is driven by transmission shaft, and transmission shaft is by drive device drives.Spiral scraper is staggeredly arranged, and the design of scraper considers will to scrape the internal surface of full annular filter cylinder.Drive the transmission shaft rotation when drive unit starts, transmission shaft drives spiral scraper rotation from top to bottom twist, and the coke powder that is attached to the filtering net inwall is scraped off.
Described stirring paddle is fixed on the transmission shaft, when transmission shaft rotates, drives and stirs the paddle coke powder of the strainer of rotation stirring from the bottom up awl section twist, prevents that coke powder is dead in accumulation of awl section and knot.
Described awl section is connected through flange with cylindrical shell.Being designed with of awl section is beneficial to the coke powder that scrapes off collection in time and discharge, also helps the dismounting and the cleaning of strainer simultaneously.
Described flow-disturbing endless tube is arranged on the cylindrical shell below, and flow-disturbing endless tube bottom has the aperture of φ 8 to φ 12.
Described drive unit adopts the mode of pneumatic or motorized motions, controls convenient and reliable.
Described transmission shaft links to each other with drive unit, and the form that two sections of transmission shaft employings or multistage connect is easy to dismounting, and repair and maintenance is convenient.
The coke cleaning of described High Temperature and Heavy Oil strainer is on-line operation, and is simple to operate, need not subsequent use and switching, and operation labour intensity is low.
