Embodiment 1

[0021] Embodiment 1, this embodiment proposes a filter device with cyclone backwashing function, such as figure 1 As shown, the filter tank 101 is included, the filter tank 101 is provided with a sieve plate 102 and a walnut shell filter material 103 arranged on the upper layer of the sieve plate 102, the filter tank 101 includes a top opening 104 and a bottom opening 105, the A connecting pipe 106 is provided at the top opening 104, and the top opening 104 is connected to the water inlet pipe 109 through the connecting pipe 106, and also includes a cleaning pump 201 and a screen pipe 301, and the connecting pipe 106 is also fed into the water through the cleaning pump The water pipe 202 is connected to the pumping port 203 of the cleaning pump 201, the connecting pipe 106 is provided with a first valve 110, one end of the screen pipe 301 is connected to the discharge port 205 of the cleaning pump, and one of the other ends is It is connected with the blowdown pipe 401, and th...

Embodiment 2

[0030] Embodiment 2, based on the filtering device in Embodiment 1, this implementation proposes a filtering method and a backwashing method for the aforementioned filtering device. The structural features of the filtering device can be referred to in Embodiment 1, and will not be described here. To repeat, the filtering method and the backwashing method of the present embodiment include the following steps:

[0031] During the filtration process, the first valve is turned on, and the oily sewage enters the filter tank through the connecting pipe and the top opening successively from the water inlet pipe. The walnut shell filter material absorbs and intercepts the solid particles and crude oil particles in the dispersed phase, and the water molecules in the continuous phase After passing through the walnut shell filter material and sieve plate, it is discharged from the bottom opening;

[0032]In the backwashing process, the first valve is closed, the cleaning pump is working,...

Abstract

The invention discloses filtering equipment with a vortex backwashing function, a filtering method and a backwashing method of the filtering equipment. The filtering equipment comprises a filter tank, wherein a sieve plate and a walnut shell filter material which is arranged on the upper layer of the sieve plate are arranged in the filter tank; the filter tank comprises a top opening and a bottom opening; a section of connection pipe is arranged at the top opening; the top opening is connected with a water inlet pipe through the connection pipe; the filtering equipment also comprises a cleaning pump and a sieve pipe; the connection pipe is also connected with a pumping opening of the cleaning pump through a cleaning pump inlet pipe; a first valve is arranged in the connection pipe; one end of the sieve pipe is connected with a discharge hole of the cleaning pump; one path of the other end of the sieve pipe is connected with a blow-off pipe; the other path is connected with a jet pipe; a second valve is arranged in the blow-off pipe; a screen is arranged at the joint of the sieve pipe and the blow-off pipe; and a cleaning water inlet connected with a cleaning water pipeline is also formed in the top of the filter tank. According to the filtering equipment disclosed by the invention, the material running phenomenon is avoided, the filter material is thoroughly regenerated through arrangement of the cleaning pump, and the service life of the filter material is prolonged.

Description

technical field [0001] The invention relates to a filter device, in particular to a filter device with a swirl backwash function, a filter method, and a backwash method. Background technique [0002] Due to its own hardness, ideal specific gravity, porosity and multi-facetness, and special physical and chemical treatment (to remove its pigment, fat, grease, and charged ions), the walnut shell filter material has a strong performance in water treatment. Excellent oil removal performance, solid particle removal, easy backwashing and other excellent properties, walnut shell filter media have been widely used in oily sewage treatment in oil fields, industrial wastewater treatment and civil water treatment. The walnut shell filter has a good effect of filtering oil in water, but there are many problems in the actual operation, the most prominent of which is the running of the filter material during the backwashing process, the filter material is not cleaned thoroughly, and the fi...
