Problems solved by technology

These kinds of filter equipment can basically meet the treatment requirements of high turbidity circulating water; however, these kinds of traditional filters have the defects of long backwashing time and large backwashing water consumption during use, because the filter material and The relative speed between the backwashing water flows is low, so that the backwashing water does not wash the filter material thoroughly; in addition, the traditional filter has the disadvantages of large floor area and low treatment efficiency.

Embodiment Construction

[0030] Such as figure 2 As shown, the present invention provides a high-efficiency backwash filter device, including a filter unit 2, the middle part of the filter unit 2 is horizontally provided with a filter plate 3, and the filter plate 3 divides the filter unit 2 into an upper chamber and a lower chamber, A fiber filter material 32 is arranged above the filter plate 3, that is, in the upper chamber, and a plurality of filter tips 31 are evenly distributed on the filter plate 3, and a through hole is arranged on the filter plate 3, and a filter tip 31 is arranged on each through hole. , the through holes correspond to the filter tip 31 one by one. In the process of backwashing, the high-pressure gas is sprayed upwards from the filter nozzle 31, and the fiber filter material 32 on the filter plate 3 is vertically purged from bottom to top, which is used to increase water and fiber filter material 32, fiber filter material The shear force and collision friction between the ...

Abstract

The invention relates to an efficient backwashing filtering device and a multilayered filter provided with the device. The efficient backwashing filtering device is provided with a filtering unit, so that high-turbidity circulating water can be filtered and backwashing can be carried out on a fiber filtering material, and therefore, regeneration of the fiber filtering material is realized and the filtering effect is enhanced; in a backwashing process of the fiber filtering material, high-pressure air in a high-pressure airflow pipeline is sprayed out from a nozzle on an outer sleeve, and suspension matters and oil, which are intercepted by the fiber filtering material, can be completely removed, so that the fiber filtering material is completely regenerated; the backwashing time can be greatly shortened and the water use amount of backwashing is saved; the backwashing and pollutant removing effects are relatively good; and the multilayered filter provided with the device comprises a plurality of stacked filtering units, so that the occupied areas of a filter is reduced, the utilization rate of a land is increased and the filtering efficiency is improved.

Description

technical field [0001] The invention belongs to filter material filter equipment for high turbidity industrial circulating water, in particular to a high-efficiency backwash filter device and a multi-layer filter with the device. Background technique [0002] Existing filter material filters for high turbidity industrial circulating water mainly include sandstone filters and multi-media filters filled with various filter materials. These kinds of filtering equipment can basically meet the treatment requirements of high turbidity circulating water; however, these kinds of traditional filters have the defects of long backwashing time and large backwashing water consumption during use, because the filter material and The relative speed between the backwashing water flows is low, so that the backwashing water does not wash the filter material thoroughly; in addition, the traditional filter has the disadvantages of large floor space and low treatment efficiency.
