Sewage UV disinfection module UV sterilization module

Sewage UV disinfection module UV sterilization module

Sewage UV disinfection module UV sterilization moduleThe sewage treatment meets the first-class A standard. Imported low-voltage high-intensity ultraviolet lamp tube, with a warranty of 12000 hours. Band 253.7nm, zero ozone band.

1) UV lamp rack component

Each UV lamp rack component includes a UV lamp tube, a sleeve, and a mechanical automatic cleaning device;

Each ultraviolet lamp tube is embedded in a separate quartz sleeve, with one end of the sleeve being a closed end and the other end sealed by a lamp tube sealing structure (rubber mechanical sealing structure);

The sealing end of the quartz sleeve is fixed inside the frame with an O-ring, and the rear is pressed and sealed. The quartz sleeve does not come into contact with any steel body on the frame, and it will not come out during automatic cleaning;

The steel structural parts on both sides of the frame of the quartz sleeve without protruding ultraviolet lamp tube rack;

The design of the UV lamp rack should take into account the convenience of factory operators in replacing lamps and quartz sleeves, as well as the ease of operation, installation, and maintenance;

Each UV lamp rack component meets the IP68 sealing level;

All welded metal components in contact with sewage are made of 316L stainless steel;

The mechanical automatic cleaning structure is fixed within the frame of the ultraviolet lamp rack.

4) Quartz casing (imported)

The wall thickness of the quartz casing is 1.5mm;

The ultraviolet transmittance of quartz tubing shall not be less than 90%;

One end of the quartz sleeve should be a dome shaped sealed end.

2) UV lamp tube (imported)

The lamp tube is a low-pressure high-strength mercury lamp with a rated power of 320W;

The ultraviolet output of a single low-voltage high-strength lamp tube at 253.7nm shall not be less than 100W;

The lamp filament is made of special alloy tungsten wire, with high melting point and boiling point, which is not easy to evaporate. The ultraviolet lamp ensures a lifespan of at least 12000 hours when operated in automatic control mode;

The circuit connection part is located at one end of the lamp tube;

UV lamps are non ozone producing lamps;

3) Sealing of lamp tube end and lamp holder

The underwater quartz sleeve of the UV disinfection system rack is sealed by 316L stainless steel nuts and compression O-rings with the steel sleeve interface on the rack, preventing direct contact between the sleeve and the steel body;

The quartz sleeve nut on the rack has a rolled surface for gripping during fastening, and no tools are required for installing or removing this sleeve nut;

The lamp tube is fixed by a PVC molded lamp holder and has double-layer sealing;

There is a secondary sealing silicone rubber mechanism between the lamp tube, sleeve, and rack to prevent the lamp tube from breaking and leaking into the rack, affecting the operation of other lamp tubes;

The second level seal inside the lamp holder isolates the lamp from the UV rack and other lamp tubes;

When the quartz sleeve ruptures, the double-layer seal on the lamp holder can prevent moisture from entering the frame of the lamp rack and invading the wiring connections with other lamps;

The lamp holder is equipped with a UV resistant PVC mold pad to prevent contact between the quartz sleeve and the steel pipe.

5) UV lamp rack frame

The frame of the UV lamp rack is made of 316L stainless steel and can be suspended above the sewage in the water channel without being fixed. All UV modules can be fixed without being tied tightly;

The frame of the UV lamp rack must be tightly arranged in a matrix structure to provide a lamp arrangement;

The frame design of the UV lamp rack has a shading device to prevent UV rays from leaking outside the water channel.

8) Electronic ballast cabinet

The ballast is designed as a high-power factor electronic ballast controlled by a microcomputer processor, with a power factor of 0.98;

Environmental temperature: 60 ℃;

If any UV lamp fails, the electronic ballast will automatically restart twice;

The electronic ballast is controlled by a microprocessor, and each electronic ballast independently controls one ultraviolet lamp tube, providing the working status of each ultraviolet lamp and transmitting information to the data acquisition circuit board of the control system. The internal microprocessor of the electronic ballast can adjust the output power of the ballast according to these external signals, and output ultraviolet light in proportion to the intensity of the input control signal, so that the amount of ultraviolet light can be adjusted linearly and continuously within the range of 50% to 99.99%, achieving the adjustment of the power supply of the ultraviolet lamp to maintain sufficient sterilization ability and appropriate power consumption;

7) UV lamp source circuit part

The UV lamp rack is divided into a power distribution system for each rack. Including a power distribution system, an electronic monitoring system, and waterproof joints;

Transmit signals from the electronic monitoring system to the distribution system, and control the distribution system to input power to each rack in the module;

6) Water level control system

The water level control system adopts a non powered self flowing overflow weir, which does not require any external power (such as electricity);

The structure of the overflow weir (see attached system layout plan for details) ensures that a * * * water level will be maintained at zero flow, and the * * * water level will still be higher than the position of the lamp tube; At peak flow, a small increment of water level change will be maintained, with the increase in water level not exceeding 5 cm;

The upper part of the weir overflow method is adopted, so the system head loss is relatively small;

Overflow weir material: 304 stainless steel.

9) Control section

Environmental temperature: 40 ℃;

Power supply (3/N/PE): 380V/450V, 50/60Hz;

The standard configuration of PLC is to use the product;

The electronic and electrical components used in the system are all imported products;

Control includes programmable control systems to achieve data collection and control;

There are the following working states in the human-machine interface system: on/off status of each ultraviolet sterilization lamp; The total operating time of each ultraviolet lamp tube (in hours); Each ultraviolet lamp group runs/stops;
