10. Current Situations
Recovery system-Current situation of galvanized wire shielding gas
Mixed gas
Most annealing furnaces use (5%-75%)
nitrogen-hydrogen mixed gas as the
protective gas.
Composition
The tail gas contains nitrogen and hydrogen,
some sealing nitrogen and impurities not
exceeding 1%.
Discharged directly
Most exhaust gas is burned directly, which not only causes a lot of waste of resources, but also pollutes the environment.

11. Save more than 80%
This system is added at the end of the heat treatment furnace to purify and remove impurities mixed in the
protective gas, and the purified qualified gas is then introduced into the furnace for recycling.

13. Collect
The exhaust gas is cooled
before entering the tank and
enter recovery system.
1
Dust and oil removal
The exhaust gas enters the oil absorber and filter for two-stage treatment,
which can deeply remove dust, oil and other impurities.
2
Deoxygenation and cooling
The oxygen is removed from the reactor through a heat exchanger.
3
Removal of other impurities
The gas is deeply degreased, dehydrated, and decarbonated with trace impurities such as carbon dioxide through a PSA to obtain qualified purified gas.

Flow Process
Introduction to Recovery System-Technological Process

14. Ensure stable working conditions in the furnace
The recovery port of the furnace is equipped with a storage tank to ensure
that the working conditions in the furnace are not affected by the adjustment
of the working conditions of the recovery system;
Automatic flow adjustment
The Roots blower adopts variable frequency control, so the flow of the recovery
system can be automatically adjusted according to the production situation;
Pressure alarms
The recovery system inlet and outlet and before and
after the Roots blower are equipped with pressure
alarm functions to ensure gas safety
Oxygen remove
There is a deoxygenation unit inside the system to reduce the oxygen content
of the recovered gas, ensuring that the oxygen content in the recovery process
will not accumulate and cause danger;
Online monitoring
Equipped with online oxygen analyzer to continuously monitor the oxygen
content of the recovered gas online 24/7, and equipped with an audible
and visual alarm for high oxygen content;
Interlocking control function ensures continuous
gas supply
The original gas supply system and recovery system are interlocked to
ensure that the heat treatment furnace can obtain protective gas under any
circumstances;
Security and Reliability
Our company takes the following measures based on the user's on- site operating conditions to
ensure the safety and reliability of the device operation.

16. The knob operation is intuitive and simple. Users only
need to turn on the power and turn the knob of the
device to be turned on to the running state, and the
device can be operated.
Easy start and stop
The flow process dynamically displays the gas flow
direction, valve status, dryer and deaerator working
status, pressure, oxygen content, flow rate, etc. in real
time on touch screen;
Dynamic display
This system can be equipped with remote monitoring to
transmit the real- time operation screen and parameters
to the network. Remote monitoring can be achieved by
entering the address and login password through a
computer or mobile phoneconnected to the network.

1) Lead the protective
gas from the overpressure
discharge ports in each
zone of the furnace top
into the recovery system.
2) The recovered gas is
connected to the original
protective gas delivery
pipeline and introduced
into the furnace from the
original protective gas
inlet.

18. Case study-customer data
For a production line of a customer, the gas used is divided into two types: sealing nitrogen and protective
nitrogen- hydrogen mixed gas:
1) Sealing nitrogen 500- 600Nm³/h;
2) Protective gas is a nitrogen- hydrogen mixed gas with a hydrogen content of 3%, with a flow rate of
about 900- 1000Nm³/h;
Among them, the sealing nitrogen is not recycled, only the protective nitrogen- hydrogen mixed gas is
recycled; therefore, this project can be designed according to the recycling volume of 1000m³/h.
