Problems solved by technology

[0004] The purpose of the present invention is in order to overcome prior art (1) need to add agitator thereby bring pollution source, noise, failure rate to rise; (2) reaction time is long, is difficult to accomplish continuous processing; (3) catalyst carrier, lamp tube protection It is difficult to seal the pipe and the upper and lower ends; (4) The processing capacity is small, and it is difficult to expand; (5) Since the intelligent control is not realized, there is a possibility that the lamp will continue to run when it is broken, which will cause the problem of drinking untreated water by mistake. It is difficult to ensure safety; (6) The disadvantages of complex structure and inconvenient installation and maintenance provide a continuous processing, intelligent control, free expansion, simple structure, no special sealing requirements, safety, static operation, low manufacturing and operating costs , Continuous intelligent control photocatalytic water quality deep purification device with good water purification effect

Embodiment 1

[0029] figure 1 , 2 , a kind of continuous intelligent control photocatalytic water quality deep purification device shown in 3, it comprises casing (water storage tank) 11, photocatalytic vertical reactor 8, automatic regulating valve 2, pre-filter 3, water level controller 5. Hub 6;

[0030] The photocatalytic vertical reactor includes a reactor shell 8-15, an ultraviolet lamp 8-1, a photoelectric sensor 8-2, a ground-sealed glass sleeve 8-3 outside the lamp, and a photocatalyst film carrier 8-4; the reactor shell The body 8-15 is cylindrical in shape, and the ultraviolet lamp 8-1 is fixed in the ground-sealed glass casing 8-3 with a fixed plug 8-7 and is fixed together at the center of the reactor housing 8-15, and is connected with the reactor housing. The bottom of 8-15 is locked with a groove, and the upper part is fixed with the locking head 8-14 of the movable cover 8-12 with rubber screw 8-6; the photocatalyst film carrier 8-4 is placed in the bottom groove inside t...

Embodiment 2

[0037] On the basis of the structure of Example 1, an automatic pressure equalizing distributor 4 is used to connect 4 stages of 5 reactors in parallel through the transfer pipe 10 to form a monomer, and then 2 monomers are connected in parallel (retest structure) to expand the capacity ( Equivalent to community use), use vanadium ion-doped modified titanium dioxide photocatalyst, use 30 watts of 365.0nm wavelength ultraviolet lamps, the thickness of the water treated in the reactor is 3mm, and the tap water meets the direct drinking standard after treatment.

Abstract

The present invention relates to a continuous intelligent controlled photocatalytic water quality deep purification equipment, including box body, photocatalytic vertical reactor, automatic regulating valve, pre-filter, water level controller and collecting device, etc. It is characterized by that said photocatalytic vertical reactor includes its shell, UV lamp, photoelectric sensor, glass double-pipe and photocatalyst film carrier. Said photocatalytic vertical reactor is placed in the middle portion of the box body, and it is equipped with a PLC intelligent controller which can be used to make conversion of signal from water level controller and UV lamp and photoelectric sensor power supply and control signal to control opening or closing of the regulating valve so as to implement automatic control.

Description

technical field [0001] The invention relates to a continuous intelligent control photocatalytic water quality deep purification device. Background technique [0002] As we all know, the use of chlorine gas as an oxidant to disinfect and sterilize tap water has its fatal weakness, that is, it will generate various chlorine-containing organic compounds such as chloroform, chloroethane, carbon tetrachloride and other intermediate products. Most of these organic compounds that cause secondary pollution It is a priority to control pollutants, which will endanger human health after drinking. Using ozone to disinfect and sterilize tap water is safer than chlorine, but it will also form some toxic intermediate products, and the maintenance time of ozone is short, the water quality tastes bad, and the cost is high. Advanced treatment with activated carbon adsorption, polymer filter element filtration, etc. can only remove large suspended particles, inorganic ions and some organic su...
