Abstract
The utility model relates to a high-flow screw-type automatic decoking quenching oil filter which comprises a barrel body (13) of the filter, an oil inlet (1) and an oil outlet (6), wherein, the oil inlet (1) and the oil outlet (6) are arranged on both sides of the barrel body. A vent hole (3) and a drain outlet (10) are respectively arranged at the upper part and the bottom end of the barrel body (13). A filter screen (8) which is made of stainless steel is arranged in the barrel body. The utility model is characterized in that a screw type scraping brush (7) is arranged on the inner side of the filter screen (8). Brush hair of the scraping brush contact the filter screen (8). The screw type scraping brush (7) is connected with a speed reducing motor (2) through a center shaft (11). The utility model can be automatically decoked. The utility model has the advantages of reasonable structure, long maintenance period and convenient operation.
Description
The spiral automatic coke cleaning quench oil filter of the big flow of the utility model is the crucial filter plant in the quench oil system in the ethylene production line.
In original quench oil system, its filter comprises filter cylinder (13), be arranged at oil-in (1), the oil-out (6) of cylindrical shell both sides, top and bottom at cylindrical shell (13) are respectively arranged with drain (3) and sewage draining exit (10), in cylindrical shell, be provided with the stainless steel screen pack, be provided with in the bottom of cylindrical shell and purge mouth.The deficiency that this device exists is that screen pack stops up easily, and quench oil circulating pump erosive wear is serious, and maintenance period is short.Production efficiency is low, and labour intensity is big.
The purpose of this utility model is to propose the spiral automatic coke cleaning quench oil filter of this big flow, and it is simple in structure, easy to manufacture.From use angle, easy to use, can clean automatically, it is convenient to change.And reduced labour intensity, and having prolonged maintenance period, maintenance cost reduces, and has improved production efficiency.
The technical scheme that realizes above-mentioned purpose is: the spiral automatic coke cleaning quench oil filter of this big flow comprises filter cylinder (13), be arranged at oil-in (1), the oil-out (6) of cylindrical shell both sides, top and bottom at cylindrical shell (13) are respectively arranged with drain (3) and sewage draining exit (10), in cylindrical shell, be provided with stainless steel screen pack (8), it is characterized in that: be provided with a screw type wiper (7) in the inboard of screen pack (8), the bristle of wiper contacts with screen pack (8), and described screw type wiper (7) links to each other with reducing motor (2) by central shaft (11).Stainless steel screen pack (8) adopts double-decker, and Intranet (12) and outer net (8) are connected to one, and locate to set up nitrogen mouth (5) and steam port (4) at the drain (3) of cylindrical shell (13), to put on the realization purging mode.Described Intranet (12) and outer net (8) are welded as a whole, and the Intranet pore size filter is less than the outer net pore size filter.The shared mouth of pipe of described drain (3), nitrogen mouth (5) and steam port (4).
Accompanying drawing is the structural representation of utility model.
Below in conjunction with accompanying drawing the utility model is further described.As shown in the figure, quench oil enters filter from oil-in 1, and after filtering by filter core 8, quench oil is by oil-out 6 outflow filters.Drain 3, steam blowing mouth 4, nitrogen mouth 5, sewage draining exit 10 are all closed at this moment.After the pressure reduction into and out of 1,6 of hydraulic fluid ports acquires a certain degree, motor 2 startings, the cleaning of filter screen is carried out in 7 rotations of screw type wiper automatically.After the pressure reduction of 1,6 of import and exports recovered rated value, motor 2 cut off automatically, and the dirt that scrapes is deposited on the bottom of filter, periodic cleaning.The structure of screw type wiper 7 is that a strip screw type brush links to each other with central shaft 11 by some poles, and 9 is axle sleeve.
When the automatic cleaning of motor can not recover the rated differential head value, close into and out of hydraulic fluid port 1,6.Motor power cuts off, and drain 3 and nitrogen mouth 5 are closed, and purges mouth 4 and opens, the steam of HTHP enters filter, and the dirt that stops up screen pack is carried out boiling, allows its liquefaction or be separated into fine particle, fall into filtering bottom, this moment, sewage draining exit 10 was opened.When opening of sieve is reached 95% above through hole by cleaning, again nitrogen mouth 5 is opened, purge mouth 4 and close, carry out high pressure nitrogen and purge, after reaching the perforation of 100% opening of sieve.This moment, other state of various mouthfuls was constant, the state of can resuming work.Open into and out of hydraulic fluid port 1,6, other is all closed.
In existing quench oil filter, drain 3, purging mouth 4, nitrogen mouth 5 are distributed in the different parts of cylindrical shell.Cylindrical shell perforate quantity is many, has weakened the rigidity and the intensity of cylindrical shell, the manufacturing cost height.And this filter has taken into full account this point, and it is one that drain 3, purging mouth 4 and nitrogen mouth 5 are closed three.Neither the use of influence production has made things convenient for operation simultaneously again.Simplify the technology arrangement of pipeline in the filter system, saved investment, easy to maintenance.
In existing quench oil filter apparatus, all are filters of low discharge, overanxious net is the individual layer stainless (steel) wire, water environment capacity is poor, efficient is low, valid circulation area is little, thereby can not satisfy high-quality and efficient, low consumption in the modern production.Thereby restricted the raising of producing, for addressing this problem, the valid circulation area of this filter increases to 3.3m
2More than, and screen pack employing double-decker, being welded by stainless steel Intranet 12 and outer net 8, the overanxious aperture of Intranet has made full use of screen pack less than the outer net pore size filter.Flow expansion, water environment capacity is strong, production efficiency improves purpose have been reached.
