Description

Novel waste heat power generation circulating water filters device

Technical Field

The utility model relates to a water treatment field specifically is used for the filtration purification of power plant's circulating water.

Background

With the development of industrial construction, regional water resources are gradually in shortage, power supply enterprises must adopt circulating cooling water, wherein circulating water filtration is an indispensable link for water use of power plants, and the quality of filtration equipment directly influences the normal production of the enterprises. The filter cloth filtering technology is a novel surface filtering technology developed in the last decade, has the characteristics of land occupation saving, low early investment, continuous operation, low operating cost and the like, and is widely applied to circulating water treatment of power plants. However, in the filtering process of the filter cloth, the phenomenon that suspended particles are not cleaned on the surface of the filter material layer occurs, so that the subsequent process supporting operation is influenced by the system blockage, and the development of the efficient filter cloth device is very necessary.

The prior patent (application number: CN201010217143. X) discloses a self-cleaning cloth filter, which comprises a filter body, a central pipe, a filter disc, a water inlet pipe, a water outlet pipe, a cleaning water outlet pipe and a liquid level meter; the motorised valve of intaking is opened earlier before the operation, the motorised valve of play water is opened, wash the water motorised valve and close, sewage at first gets into the center tube through the limbers through the inlet tube, inside rethread center tube limbers and filter disc limbers got into the filter disc, when sewage flows to the filter disc outside from the filter disc in, the surface of filter cloth is detained to the suspended solid of filter cloth in the filter cloth, rivers after the processing go into in the cell body, flow out from the outlet pipe at last, close the water motorised valve during washing, make the internal water level of cell rise, close the motorised valve of intaking, open simultaneously and wash the water motorised valve, in water flows into the filter disc from the filter disc outward, the suspended solid in the fibre is by the sanitization, close the washing water motorised valve, open the motorised valve simultaneously and go. The fiber membrane treatment replaces an initial sedimentation system, and the fiber membrane equipment is abraded due to the lack of an early-stage deslagging device, so that the equipment maintenance cost is increased. When the inside surface of the filter cloth is dirty and blocked, the filter disc needs to be disassembled for manual cleaning to clean thoroughly, which increases labor cost.

Furthermore, the telescopic fixing device is arranged at the center of the side surface of the central cylinder, and a graphite rotating shaft is arranged in the telescopic fixing device and connected with the central cylinder and can be used for rotating the central cylinder.

Furthermore, a sealing ring device is arranged at the outlet end of the water outlet connector, so that the outlet end is ensured to be watertight with the interface of the next equipment unit.

The utility model has the advantages that:

1. the sucker attached to the surface of the filter cloth has small area and simple structure, and the filter cloth can not be blocked for filtering under the normal filtering condition.

2. The fan-shaped filter disc is embedded on the central cylinder, so that the assembly and disassembly are convenient and convenient, and the cleaning and maintenance are convenient.
