[0107] see Figure 7 The difference between the second embodiment of the present invention and the first embodiment is that the compressed air energy storage part is an energy storage structure 600' with a closed space, the bottom of the energy storage structure 600' is connected to the body 200', and the energy storage The upper space of the structure 600' is an energy storage space. The internal space of the energy storage structure 600' constitutes a part of the filtrate space 230' of the energy storage backflush filter.

[0108] Wherein, the bottom of the energy storage structure 600' can be connected to the top of the body 200' to seal the air in the upper space of the energy storage structure 600'.

[0109] The energy storage structure 600' can also be connected to the side wall of the body 200', wherein the bottom of the energy storage structure 600' is higher than the filtrate outlet 250', so that the air is enclosed in the upper space of the energy storage structure ...

Abstract

The invention discloses an energy-storage backblowing filter and a filtration and filtration-regeneration method thereof. The energy-storage backblowing filter comprises a body, and an original liquid inlet valve, a filtration clear liquid outlet valve and a filter cake outlet valve which are correspondingly connected with the body, wherein a filter screen is arranged inside the body and divides the interior of the energy-storage backblowing filter into an original liquid space and a filtration clear liquid space; a power supply device is connected with the original liquid inlet valve; the original liquid inlet valve and the filter cake outlet valve communicate the original liquid space; the filtration clear liquid outlet valve communicates the filtration clear liquid space; meanwhile, the filter also comprises an air compression energy-storage member which is arranged on and connected with the body; the filter cake outlet valve is opened before filtration so as to naturally fill air into the interior of the energy-storage backblowing filter; the air compression energy-storage member forms an energy-storage space in individual or in cooperation with the body; and the air filled in the interior of the energy-storage backblowing filter undergoes compression and energy storage and is enclosed in the energy-storage space when filtration. The energy-storage backblowing filter provided by the invention has the advantages of simple structure, simple and convenient operation, and low equipment and operation costs.

Description

technical field [0001] The invention relates to a filter, in particular to an energy storage reverse blowing filter. The present invention also relates to the filtration and filtration regeneration method of the energy storage backflushing filter. Background technique [0002] The filter is an important component of the fluid circulation system, which achieves the purpose of liquid reuse through solid-liquid phase separation. [0003] Generally, filtration can be used for solid-liquid phase separation, such as the separation of crystals in the chemical production process, the removal of particulate matter in the process of lubricating oil reuse, etc. Sedimentation methods can also be used, such as water-mud separation in sewage sedimentation tanks. When the particles of the solid phase are finer, the sedimentation time is longer and the volume of the sedimentation tank is larger. Relatively speaking, the filtration method takes a short time, is easy to process online, and ...
