Embodiment 1

[0017] Embodiment 1: Two-way backwash pressure filter tank Take the tank body 1 with a diameter of 4 m as an example.

[0018] figure 1 It is a structural schematic diagram of the present invention, which shows the overall structure of the filter tank. As shown in the figure, the double-way backwash pressure filter tank is composed of a tank body 1, an agitator 2 and a filter bed 3, and the agitator 2 is in the tank body 1 is set vertically in the center, and the agitator 2 is composed of a motor, an electric reducer, a stirring shaft and blades. The tank body 1 has a water inlet 4 and a water outlet 5, and the tank body 1 is connected with an overflow pipe 7 and an exhaust pipe 8. Screen pipe 14 and screen pipe 14a are all housed on water inlet 4 and water outlet 5, and purpose is to prevent fine filter material from being washed away by water flow. A filter bed 3 is installed inside the tank body 1, and a filter material is placed on the filter bed 3. The filter material c...

Abstract

The invention discloses a double-way backwashing pressure filter tank and a backwashing method thereof. The double-way backwashing pressure filter tank comprises a tank body (1), a stirrer (2) and a filter bed (3), wherein the stirrer is vertically arranged at the center of the tank body; a water inlet (4) and a water outlet (5) are arranged on the tank body; sieve pipes (14 and 14a) are arrangedon both of the water inlet (4) and the water outlet (5); the tank body is connected with an overflow pipe (7) and an exhaust pipe (8); the filter bed is mounted in the tank body; the water inlet is connected with a filtering water inlet pipe (10) and a backwashing draining pipe (11); the water outlet is connected with a filtering water outlet pipe (12) and a backwashing water inlet pipe (13); valves (15, 15a, 15c, 15d, 15e and 15f) are arranged on the overflow pipe, the exhaust pipe, the filtering water inlet pipe, the backwashing draining pipe, the filtering water outlet pipe and the backwashing water inlet pipe respectively; a sewage draining outlet (6) is formed at the upper part of the tank body; the sewage draining outlet (6) is connected with a sewage draining pipe (9); and a valve (15b) is arranged on the sewage draining pipe (9). The double-way backwashing pressure filter tank can be used for solving the problems that the filter backwashing is incomplete and the sieve pipes are easily blocked.

Description

technical field [0001] The invention relates to a filtering device, in particular to a double-path backwashing pressure filter tank and a backwashing process thereof. Background technique [0002] With the continuous increase of oil production in oil fields, it will inevitably cause the underground oil level to drop and affect the oil production. In order to stabilize production, water must be injected into the ground to raise the oil level and facilitate oil recovery. When re-injecting oily sewage, it must pass through a water treatment mechanical filter, and after degreasing treatment, it can be re-injected to achieve the desired effect. However, after the filter has been in operation for a period of time, the dirty oil and solid impurity particles adsorbed and retained on the surface of the filter material on the filter bed are saturated, and the filter material loses its filtering function. The adsorbed oil and impurity particles restore the filtering function of the f...
