Nitrification tail gas absorption 8-lamp 8-button explosion-proof control box

Scope of application:Nitrification tail gas absorption 8-lamp 8-button explosion-proof control box
1.1 Classification of Hazardous Areas in Explosive Gas Environments
Different homes and regions are divided into explosion hazard zones according to their respective standards. I divide explosive gas environments into Zone O, Zone 1, and Zone 2 based on the frequency and duration of the occurrence of explosive gas mixtures. (Consistent with IEC Electrotechnical Committee)
Zone 0: An environment where explosive gas mixtures are continuously present or present.
Zone 1: An environment where explosive gas mixtures may occur during normal operation.
Zone 2: An environment where explosive gas mixtures are unlikely to occur during normal operation or where explosive gas mixtures only exist for a short period of time if they do occur.
Zone 0 generally only exists in sealed containers, storage tanks, and other internal gas spaces, and in the actual design process, Zone 1 is rarely present, mostly belonging to Zone 2.

Structure and characteristics:

The explosion-proof control box is designed and manufactured in accordance with the standards of GB3836.1-2000 "Electrical Equipment for Explosive Gas Environments: General Requirements", GB3836.2-2000 "Electrical Equipment for Explosive Gas Environments Part 2: Explosion proof Type" d '", and GB3836.3-2000" Electrical Equipment for Explosive Gas Environments Part 3: Increased Safety Type "e'". It has been inspected and approved by the inspection authority and issued an explosion-proof certificate.

A、 The shell is made of cast aluminum alloy and sprayed with plastic on the surface. The main chamber adopts an explosion-proof structure, and the wiring chamber adopts an increased safety structure. Optional components include circuit breakers, AC contactors, thermal relays, transformers, fuses, Ex explosion-proof control buttons, signal lights, and transfer switches. The distribution box adopts a modular design, and various circuits can be freely combined. The selection of electrical components can be determined by the user, and its structure is compact and its appearance is beautiful. Both steel pipes and cables can be used for incoming and outgoing lines, and the direction of the incoming and outgoing lines can be determined by the user's requirements.

B、 Non standard explosion-proof box: The shell is welded with steel plates and sprayed with plastic on the surface. The main chamber and wiring chamber are both designed with explosion-proof structures, and can be optionally equipped with high breaking circuit breakers, AC contactors, thermal relays, control buttons, signal lights, and other components. They can be opened and closed by operating the handle on the shell cover, with reliable performance and indicator lights. Both steel pipes and cables can be used for incoming and outgoing lines, and the direction and internal components of the incoming and outgoing lines can be determined by user requirements.
