Description

Final-stage filtering device for mist water supply system

Technical Field

The utility model relates to a mist water supply system, in particular to a final stage filtering device for the mist water supply system.

Background

The misten system is a water atomization system which generates superfine mist particles (more than 70 percent of the diameter is less than 4 microns) through high-pressure micropores. The atomized fine fog particles have the functions of cooling and humidifying, dust suppression and rich negative oxygen ions, and are widely applied to occasions such as urban buildings, garden landscapes, stage effects and the like.

The existing foison water supply system is composed of a pre-filter device 1.1, a water pressurizing pump 2.1, a water supply electric control valve 3.1 and a water mist nozzle 4.1 as shown in fig. 9. The pre-filter device 1.1 is used for carrying out coarse filtration on water from an external water supply pipeline 5.1 and then conveying the water to a water supply pressure pump 2.1; the water pressure pump 2.1 pressurizes the water entering the pump cavity to a set pressure, and the water is conveyed to the water mist spray head 4.1 through the water supply electric control valve 3.1 and the water supply branch pipe 5.1 to carry out artificial mist generation on the environment.

The fog-sen water supply system has the defects that the spray head is blocked frequently in the operation process, and the spray head is blocked usually under the intermittent operation working condition of the fog-sen system or under the restarting working condition after long-time non-operation. Because the water supply pressure of the foison system is very high, generally 5MPa to 7MPa, the operation must be suspended for overhauling after the spray head is blocked, so that the operation and maintenance cost of the foison system is greatly increased, and the operation working efficiency of the foison system is reduced.

The nozzle blockage is mainly divided into three categories including mechanical blockage, chemical blockage and biological blockage. Mechanical plugging is typically the predominant form. The mechanical blockage mechanism is that larger particles still exist in the water body after passing through the preposed filtering device 1.1 and enter the gaps of the micropores of the water spray nozzle 4.1 along with the water body, and stay in the micropores of the water spray nozzle 4.1 to form blockage; and in addition, in the water supply pipeline, the retained fine particles are accumulated more and are adsorbed mutually to increase to block the spray head along with the increase of time. The chemical blocking mechanism is due to the chemical action of various ions in the water body to form water-insoluble compounds, such as CaCO₃、FeO₂Stay in the water mist spray head4.1 in the micropores; the biological blocking mechanism is that because of algae tips, bacteria head microorganisms and organic matters in the water body, when the mist system stops running, the algae tips and the bacteria head microorganisms grow and propagate in the water body of the water supply pipeline, and when the mist system runs again, the water mist spray nozzles 4.1 micropores are blocked.

How to effectively solve the problem of water mist spray head blockage in the misten system is not reported at present.

2. When the mist water supply system works normally, 5MPa-7MPa high-pressure water conveyed by the water supply branch pipe is conveyed to each water mist spray head through the purification chamber formed by the front half shell 1 and the rear half shell 3.

3. High-pressure water enters the rear half shell 3 through the ultrafiltration membrane 4 via the front half shell 1, and fine impurities are stopped by the ultrafiltration membrane 4 and stay on the surface of the ultrafiltration membrane 4 on the side of the front half shell 1; meanwhile, the rear half shell 3 bears water pressure, so that the corrugated shell section 6 is in a stretched state, and the tension energy storage spring 7 is also in a stretched state.
