Chromium oxide refining furnace equipment
Product technical requirements:
In the process of production, chromium oxide melting furnace
produces a lot of harmful flue gas with high temperature, high dust
concentration, fine dust, easy to fly and big pollution, which
causes serious pollution to the atmosphere environment.
The whole design system of this project includes: main pipe,
cooler, pneumatic system, preprocessor, main fan, large bag dust
collector, three-way switching ash cleaning system and other parts.
Its characteristics are: the system handles the smoke volume, the
dust removal efficiency is high, the structure is reasonable, the
operation management is simple, the maintenance workload is small.
PLC program control is set to realize the automatic cleaning
operation in turn in the sub-chamber (unit) to ensure the
continuous work of the dust removal system.
Design principle:
· Air Pollution Prevention Law of the People's Republic of China;
· Environmental Protection Law of the People's Republic of China;
· Industrial enterprise design hygiene TJ36-79.
Structure features:
The low pressure pulse dust collector is designed before the
cooler, as the LM low pressure pulse dust collector cooling, can
separate most of the dust in part of the flue gas, greatly
alleviating the bag dust cleaning pressure, improve the life of the
wearing parts, reduce the working load of the air compressor.The
reasonable design of the inlet air equalizing pipe and the
diversion technology of the upper part of the ash hopper solves the
phenomenon of uneven air flow in each chamber which is often
produced by the general bag dust collector.
The dust collector is controlled by advanced Siemens programmable
controller, which has two control modes: timing and manual.
Complete system control of dust collector off-line valve, pulse
valve and ash discharge valve is realized.
