Problems solved by technology

Generally refers to petroleum refining, that is, cracking crude oil into kerosene, gasoline, diesel, heavy oil and other fuels suitable for internal combustion engines; in the process of petroleum refining, solid impurities are usually produced, if the solids are not removed in time, it is easy to give The normal operation of refining equipment affects the output and yield. Due to the poor fluidity of petroleum crude oil, it is difficult to separate the solid-liquid mixture. Difficult; in addition, due to the influence of adhesion, the filter holes of the filter plate are easy to be blocked, and it is inconvenient to remove the blockage

Embodiment 1

[0031] see Figure 1-5, a solid-liquid impact separation device for petroleum refining, including a horizontal drum 1, a solid-liquid screening drum 2, a filter baffle 3, a scraper 4, a post-filtration collection box 5 and a horizontal drum for supporting The support frame 6 of 1 is used to inject the solid-liquid mixture into the horizontal drum 1. The solid-liquid screening drum 2 is accommodated in the horizontal drum 1. The axis of the solid-liquid screening drum 2 is upward relative to the axis of the horizontal drum 1. Eccentric and distributed in parallel, the solid-liquid screening drum 2 is used to place the collected solids, which is higher than the liquid level of the above-mentioned solid-liquid mixture, and the upper end surface of the filter baffle 3 is in contact with the inner surface wall of the horizontal drum 1, specifically It is said that the filter baffle 3 and the inner wall of the horizontal drum 1 are in cooperation with the scraper. When the horizonta...

Embodiment 2

[0033] see Figure 5 , and the difference from Example 1 is that the scraper 4 and the filtered collection box 5 are slidingly fitted with the filter baffle 3, wherein the scraper 4 and the filter baffle 3 are elastically slidable, and can be used between the scraper 4 and the filter baffle A slider is set on the side where the plate 3 fits, and a chute is set on one side of the filter baffle 3, and a return spring in contact with one end of the slider is installed in the chute. Under the action of the return spring, the scraper 4 contacts The solid-liquid screening drum 2 exerts extrusion force, the filtered collection box 5 and the scraper 4 slide in the same direction relative to the filter baffle 3, and the filter gap 31 is in the shape of a trapezoidal groove and the small end is close to the inner wall of the horizontal drum 1. 31 is used in conjunction with the scraper 4, so that the scraper 4 can control the opening size of the filter gap 31, that is to say, when the f...

Embodiment 3

[0035] see Image 6 , and the difference from Embodiment 2 is that the end of the support shaft 321 located outside the horizontal drum 1 is fixedly provided with a rotating arm 7, and the free end of the rotating arm 7 is hingedly connected with the elastic telescopic rod 8 and the support plate 62, and the elastic telescopic rod 8. The structure of sleeve, rod and spring is adopted, and the structure that shrinks under normal conditions can be selected, and then the filter gap 31 on the filter baffle 3 can be controlled by the rotating arm 7 to be in the working position. When the solid matter on the upstream side of the filter gap 31 When it is too late to enter the solid-liquid screening drum 2, the accumulated solids will push the filter baffle 3 to move downstream to realize filter unloading. It has the function of automatic unloading and anti-blocking, and the elastic telescopic rod 8 is used to realize automatic control, and the cost is low. Low.

Abstract

The invention discloses a solid-liquid impact type separation device for petroleum refining. The solid-liquid impact type separation device comprises a horizontal roller, a solid-liquid screening roller, a filtering baffle, a scraping plate, an after-filtering collecting box and a supporting frame used for supporting the horizontal roller. The solid-liquid screening roller which is eccentrically arranged upwards is contained in the horizontal roller, the filtering baffle with a filtering function is arranged between the horizontal roller and the solid-liquid screening roller, the scraping plate is arranged on the upstream side of the filtering baffle and makes contact with the outer wall of the solid-liquid screening roller, and the upper end of the filtering baffle makes contact with the inner circumferential wall of the horizontal roller; the filtering baffle is located above the horizontal plane where the axis of the solid-liquid screening roller is located, so that when the horizontal roller rotates, a solid-liquid mixture can move along with the inner wall of the horizontal roller by means of the characteristic that the fluidity of original petroleum liquid is poor, a filtering notch is formed in the upper end face of the filtering baffle, and the solid-liquid mixture moving through the circular shaft can impact the filtering notch; and liquid is accelerated to pass through the filtering notch, so that solid-liquid separation is realized, and the separation efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of solid-liquid separation in petroleum refining, in particular to a solid-liquid impact separation device for petroleum refining. Background technique [0002] Petrochemical refining is a process in which crude oil or other oils are distilled without changing the molecular structure. In the process of petroleum refining, crude oil must go through a series of processes to obtain various useful petroleum products. Generally refers to petroleum refining, that is, cracking crude oil into kerosene, gasoline, diesel, heavy oil and other fuels suitable for internal combustion engines; in the process of petroleum refining, solid impurities are usually produced, if the solids are not removed in time, it is easy to give The normal operation of refining and chemical equipment affects the output and yield. Due to the poor fluidity of petroleum crude oil, it is difficult to separate the solid-liquid mixture. Difficulty...
