Puhua - Model DHL-Ex Series -Medium and High Voltage Explosion Proof Industrial Dust Collection Equipment

Explosion proof motor, certified as qualified.

• The power system consists of a motor and a fan, adopting a vertical motor structure and an integrated compact design, which reduces the machine’s footprint while ensuring negative air flow.
• The explosion-proof motor we use is from a well-known domestic brand with qualified certification, and the dust explosion-proof motor is designed to prevent.

Explosion level: Ex td A21IP65 T135 ?.

•  The circuit design of the control unit includes thermal overload, phase loss, and reverse phase sequence protection functions. The pulse-jet cleaning system is independently controlled, and the main electrical components such as internal AC contactors and thermal overload are all Schneider brand electrical components.
•  Explosion proof electrical box (variable frequency optional FFU electrical box) Explosion proof mark: Extd A21IP65 T135 ?.

Pneumatic pulse reverse blowing for dust cleaning,

filter cartridge filtration.

•  Automatic pulse spraying, with adjustable spraying frequency. The patented spray structure greatly reduces blind spots in the filter cartridge spray.
•  Filter cartridge type filtration, imported polyester fiber substrate, anti-static PTFEcoating treatment, with a filtration accuracy of over 99%for dust with an equivalent diameter of 0.3 μ m, meeting indoor emission standards, low wind resistance, and easy cleaning.

Monitoring of pressure difference inside and outside the filter, and indication of dust removal.

•  The pressure difference inside and outside the filter is monitored in real-time by a pressure difference detection gauge, which is a pointer type pressure difference gauge that is clear at a glance and practical and convenient.
•  It can display the blockage status of the filter in real time and remind the operator to perform deep cleaning and replacement of the filter cartridge.

Drawer style dust collection box, practical and convenient.

•  The dust collection box adopts a drawer style structure and is made of 304 stainless steel material. When the dust accumulates, the door panel can be opened to pull out the dust collection box for dust cleaning. After completion, the dust collection box can be sent in.Convenient, fast and practical.

Explosion proof membrane, ensuring safety.

•  Explosion relief diaphragm is a non closing pressure relief device controlled by pressure difference and has a release function. It can explode under specified temperature and pressure,relieve pressure, protect the safety of pressure bearing equipment, and ensure the safety of people’s lives and national property. In case of an explosion, it can greatly reduce the harm.

[Optional] Muffler/High Efficiency Filter/Activated Carbon Filter.

• Exhaust muffler: meets the requirement of indoor noise ≤ 75dB (A).
• High efficiency filter: meets the emission requirements of cleanrooms at the 10000/1000 level.Activated carbon filter: the need to remove odors.

[Optional] Various sensors.

•  According to user needs, vacuum suction port wind speed sensor, motor and exhaust outlet temperature sensor, exhaust outlet concentration sensor, fan air pressure sensor, etc. can be optionally selected. Equipment operation indicators and fault alarm lights can be selected according to user needs, generally using 3-color indicator lights and explosion-proof configurations.

[Optional] Explosion proof operation indicator/alarm light.

•  Equipment operation indicators and fault alarm lights can be selected according to user needs.
•  Generally,3-color indicator lights and explosion-proof configurations are used.
