Embodiment Construction

[0019] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0020] The multimedia filter system provided by the invention includes a plurality of sequentially connected multimedia filters and a control device.

[0021] Such as figure 1 As shown, a wireless communication flowmeter 3 and a wireless communication differential pressure transmission are installed on each multimedia filter, and the water inlet pipe 5 passes through the wireless communication flowmeter 3 and the first switching valve 4 and the tank of the multimedia filter. The body 2 is connected, and the two sensors of the wireless communication differential pressure transmitter are respectively arranged at the inlet and outlet of each multimedia filter. The backwash sewage pipe 7 is connected with the tank body 2 of the multimedia filter through the third switch valve 8 . The oil collection pipe 1 is connected with the upper head of the tank body 2 of the multi...

Abstract

The invention discloses a multi-medium filtering system. The multi-medium filtering system comprises a plurality of multi-medium filters which are sequentially connected and a control device, wherein each multi-medium filter is provided with a wireless communication flowmeter and a wireless communication pressure difference transmitter; the wireless communication flowmeters obtain inlet water flows of the multi-medium filters in a real-time manner; the wireless communication pressure difference transmitters obtain the pressure difference between inlet water and outlet water of the multi-medium filters, and transmit the current inlet water flows and the pressure difference between inlet water and outlet water of the multi-medium filters to the control device; and the control device controls the corresponding multi-medium filters to carry out back washing operation according to the current water inflow and the pressure difference between inlet water and outlet water. According to the multi-medium filtering system disclosed by the invention, each filter adopts the wireless communications flowmeter and the wireless communication pressure difference transmitter, and a wireless communication mode is adopted to replace the traditional wired communication mode, so that the multi-medium filtering system can effectively monitor whether each filter is drifted and the pollution level of a filter material.

Description

technical field [0001] The invention relates to an oily sewage treatment system, in particular to a multi-media filter system. Background technique [0002] At present, in industrial circulating water treatment systems, multi-media filtration systems are mostly used to remove impurities in sewage and absorb grease, so that the water quality meets the requirements for recycling. Usually, a multimedia filtration system consists of two or more multimedia filters, in which a filter material layer is formed by a variety of media, and during the filtration process, dirt in the water will gradually accumulate at the filter material layer. Because the impurity layer accumulates on the inner side of the filter material layer, a pressure difference is formed between the inner and outer sides of the filter material layer, which seriously affects the smooth progress of the filtration process of the multi-media filtration system. . Therefore, after a period of use, the multi-media filt...
