The slotted screen 6 is shown as (1) in fig. 7, and the slotted screen 6 is a fan-ring wedge-shaped slotted screen, wherein the pipe wall partial structure is shown as (2) in fig. 7 and is provided with inverted trapezoidal wedges. The fan ring wedge slotted screen pipe has higher structural strength than the conventional full ring wedge slotted screen pipe. And the inverted trapezoidal wedge seam can effectively prevent the filter material clamping shell from blocking the flow channel, so that the filter material is not easy to clamp at the circular seam, and solid particles can be easily and timely flushed out of the wedge-shaped sieve tube body under the impact of the back-flushing pressure and the flow, so that the uniformity and the stability of the filter material water passing layer can be durably and effectively maintained.

Tests prove that the material and the process of the filter medium layer can effectively increase the upper limit filter speed of the walnut shell filter from the conventional 16m/h to 20m/h, which means that the rated treated water amount of the filter can be increased by 25% under the same filter cross-sectional area, thus fundamentally realizing the reduction of the volume of equipment and the reduction of weight, and being a very positive and important innovation for space, load and precious offshore production platforms.
As shown in fig. 1, 2 and 4, the mechanical stirring device 8 is fixed on the filter tank 1, a central transmission shaft of the mechanical stirring device penetrates through the "feng" shaped water distributor 4 provided with a cylindrical transition pipe sleeve at the upper part and extends to the filter medium layer 7, and a high-low long-short double-layer blade stirring paddle 81 which is more in accordance with the design of fluid mechanics CFD calculation and flow field characteristics is configured on the mechanical stirring device 8 and is arranged in a filter material dirt receiving middle area of the filter medium layer 7 for mechanical stirring to make the filter material collide to remove oil and solid suspended matters. When the backwashing water is cleaned by mechanical stirring, external backwashing gas enters the lower part 'feng' shaped water collector 5 through the water outlet main pipe 3 (backwashing water inlet main pipe), uniformly distributed high-speed impact air flow is formed under the resistance distribution action of the wedge-shaped slotted sieve pipe 6, the filter medium layer 7 is directly stamped, the air flow with high kinetic energy continuously scrubs the surface of the filter material, and the high-speed impact air flow and the mechanical stirring are cooperated to strengthen the surface, so that the oil stain and the solid suspended matter on the filter material are more efficiently and thoroughly eluted, dense bubble groups formed by the disturbance of the impact air flow are more easily combined with dropped oil drops and solid suspended matter into a complex body which is far smaller than the water density, the upward floating of backwashing dirt is accelerated, and backwashing water is discharged through the water inlet main pipe 2 (backwashing water outlet main pipe). During backwashing, backwashing gas is firstly carried out and then backwashing water is carried out through a backwashing water inlet main pipe, air-water alternative combined backwashing is carried out, and the air-water backwashing mode is shown in figure 9. During backwashing, the backwashing water inlet main pipe can be understood as a gas-water combined backwashing main pipe.
As shown in fig. 8, the mechanical stirring device 8 is provided with a high-low-length double-layer blade stirring paddle 81, and the high-low-length double-layer blade stirring paddle 81 is divided into two layers of blades, and the upper layer of blades is longer than the lower layer of blades. The layered stirring can control the collision of the filter material and improve the collision regeneration speed of the filter material. The speed of the mechanical stirring device 8 is 60 rpm. For the horizontal walnut shell filter with a larger cross-sectional area, the mode of backwashing by combining mechanical stirring and gas-water is more uniform in filter material backwashing, higher in backwashing regeneration speed and better in reliability and stability of long-term operation of the mechanism compared with other modes.
As shown in fig. 1 to 6, the filter material scraping mechanism 9 includes a rotatable triangular scraping machine 91, scraping mechanism side girders 92, and a row support ring 93, the row support ring 93 is used for movably fixing the scraping mechanism side girders 92 inside the filter tank 1, and a series of rotatable triangular scraping machines 91 uniformly distributed along the axial direction of the filter tank 1 are suspended inside the scraping mechanism side girders 92 at both sides through rotating shafts. Because under the combined action of mechanical stirring and air scrubbing, the filter material receives very big disturbance and produces the torrent, when the backwash was accomplished, the filter material can be because of gravity subsides the recovery filter bed, and anomalous torrent can form local filter material pile tower phenomenon and backwash filtration low efficiency district or blind area theoretically, to the solution of this problem, designed by the row of support ring, the triangle of can revolving strickle the flat-bed machine, strickle the filter material of the non-drive power of constituteing jointly such as mechanism side girder and strickle the mechanism. The loose joint is fixed by a rotatable bearing, can generate rotary motion when driven by enough external force in the working process, and is generally fixed.
As shown in fig. 1-6, the rotatable triangular leveler 91 is in the shape of a triangular prism, the vertical section of the triangular prism is a regular triangle, and three side surfaces of the triangular prism are composed of a plurality of groups of leveling plates; the rotatable triangular slicking machine is designed in a mode of slightly deviating the center of gravity, namely the center line of gravity of the slicking machine is not superposed with the center line of a right triangle of the cross section but slightly deviates. At backwash and forward washing switching stage, when just being that water conservancy flow direction 180 degrees reverses, the triangle strickle the flat-bed machine of can rotating has ingeniously utilized water conservancy to reverse and the gravity center slightly inclined to one side adverse reaction upset, and asymmetric doctor-bar can be strickleed the crest filter material of piling tower to ensure the even of filter bed thickness, solved the backwash after the filter material piling tower with form the problem of filtering low efficiency district and blind area. The rotatable triangular filter material scraping mechanism with slightly deviated gravity center is simpler in mechanical transmission mechanism, higher in reliability and convenient to overhaul and maintain compared with a chain type or belt type mechanism which is complex in structure and difficult to overhaul due to mechanical faults.
As shown in fig. 1-6, the filter tank 1 is provided with a plurality of groups of quartz sight glasses 14, hand holes 15 and manholes 16. Preferably, 4 groups of quartz sight glass 14 are arranged above the rotatable triangular scraper 91 and are used for observing the scraping condition and the water distribution condition of the filter material after backwashing, and 2 groups of quartz sight glass 14 are arranged in the middle of the filter material dirt receiving area of the filter medium layer 7 and are used for online observing the self-cleaning regeneration condition and the in-tank filtering effect condition of the filter material so as to facilitate observation of the production debugging backwashing effect and judgment and setting of the working operation parameter value of the equipment.
The hand hole 15 and the manhole 16 are respectively positioned in the center and below the centers of the end sockets on the two sides of the filter tank body 1 and are respectively used for manual maintenance inside the equipment and filter material replacement.
The technical scheme provided by the invention greatly improves the maximum treatment capacity limit of a single walnut shell filter, and the specific analysis is as follows:
under the dual limiting conditions of road transportation width limitation of 4m and offshore platform interlayer working site height limitation of 7m, the maximum diameter of the walnut shell filter can only be 4m, and the maximum effective filtering cross-sectional area (diameter direction) of the walnut shell filter is 12.56m 2 (ii) a The effective filtering speed can not exceed 20m/h under the influence of the physical properties and characteristics of the filtering material and the configuration of the filtering material bed layer, so that the maximum water treatment capacity of a single tank of the vertical walnut shell filter can only be about 250m 3 H, the number of filters must be increased when the treatment amount is increased.
Although the diameter of the horizontal filtering tank cannot exceed 4m, the tank body adopts a horizontal tank form different from the traditional vertical type, 2 groups of even more uniformly distributed water inlet main pipes (backwashing water outlet main pipes) are arranged above and 2 groups of even more uniformly distributed water outlet main pipes (backwashing water inlet main pipes) are arranged below along with the increase of the length of the tank body, the overall height of the equipment cannot be increased obviously under the condition of large treatment capacity due to the arrangement form, but the maximum effective filtering area (the transverse direction of an axis) is 12.56m2+ 4m multiplied by T (T is the length of a cylinder body), the effective treatment capacity is determined by the diameter and the length of the cylinder body together, and the maximum length T of the cylinder body can be 20m. Meanwhile, the material and the process of the filter medium layer adopted by the invention can effectively increase the upper limit filtration speed of the walnut shell filter from the conventional 16m/h to 20m/h, and the rated treated water capacity of the filter can be increased by 25% under the same filtration cross section area, so that the single treatment capacity exceeding 1600m can be realized 3 H is far higher than 250m which can only be realized by the single maximum treatment capacity limit of the existing walnut shell filter 3 /h。
When the horizontal high-efficiency self-cleaning walnut shell filter provided by the invention is actually operated, the backwashing time interval frequency is adaptively adjusted according to the dirt degree of oily sewage to be treated, the backwashing preset frequency is generally 12-24 h, each backwashing time is 30min, when the dirt content of a filter material exceeds 50%, backwashing regeneration is required, the residual dirt content of the filter material after backwashing is not more than 3%, and the annual comprehensive loss reduction rate of the filter material is not more than 5%. The mechanical stirring device, the air-water combined backwashing device and the filter material leveling mechanism provided by the invention can stably control the regeneration efficiency and the loss reduction rate of the filter material, and ensure that the use and replacement period of the filter material is more than 4 years.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
