5,Atmosphere system
CE Approved, Annealing Furnace for Solar Cell Glass Substrate
 
Atmosphere control system Including air pipe and exhaust system
Air pipes: the range of flowmeter is 48 ~ 480L / min; glass rotameter control
A Entrance air curtain Entrance air curtain (divided into three rows of air intake), and the range of each flowmeter is 48 ~ 480L / min
B Air inlet in heating parts Supplement of fresh air (intake air is divided into three rows), and the range of each flowmeter is 48 ~ 480L / min
C Rubber exhaust gas A set of waste gas collection pipeline and filtration system are set, which is controlled by micro pressure negative feedback, connected with the chimney and has the ability of mixing fresh air; Reduce the pipeline temperature; Pumping capacity ≤ 30m3 / min
D Air inlet in firing parts One pipe of intake air (divided into three rows). The range of each flow meter is 48 ~ 480L / min, which is distributed in the last water jacket of the water cooling section
E Exit air curtain The exit air curtain (divided into three rows of air intake), and the measuring range of each flowmeter is 48 ~ 480L / min
F Cooling exhaust In the air cooling area, the blower blows air, and the exhaust volume is about 50m3 / min
Each atmosphere flow meter displays the actual flow
6,Cooling system:
Cooling mode of water cooling area The surface of stainless steel cooling jacket is installed with water-cooled coil pipe
Cooling mode of  air cooling section Forced air cooling with large air volume
Cooling detection  1 point water temperature detection of cooling water jacket
Alarm indication Low water pressure alarm, overtemperature alarm, exhaust low negative pressure alarm
7,Safety protection:
Belt stop button Two belt stop button is set at the inlet and outlet end plates respectively. One for belt stop,one for power off.
Alarm indication Overtemperature, temperature deviation, frequency converter alarm, thermocouple broken, low gas pressure, low water pressure, discharge audible and visual alarm
8,Temperature control system:
Temperature measurement Each control and detection point is measured independently by K-type thermocouple
Control instrument It is controlled by imported intelligent regulation module.It has many alarm protection functions, such as PID parameter self-tuning, high temperature upper limit alarm, thermocouple failure indication and so on
Heating control The heating part is powered by multiple AC contactors in groups to reduce the instantaneous current impact of the equipment on the power grid
Control mode Solid state relay
Overtemperature treatment In case of overtemperature in a certain temperature zone, the temperature overtemperature alarm system of the temperature zone will immediately send out audible and visual alarm signals, cut off the heating in the corresponding temperature zone at the same time, and the buzzer will send out continuous alarm sound
Computer control system DCS (distributed control system) control system is adopted.
Lower computer, intelligent instrument control, upper computer monitoring
Friendly man-machine interface, multiple programs are stored, which is convenient for users to edit and call
Real time display of temperature and alarm status.The data can be stored and printed out.
Provide furnace temperature calibration function to better fit process requirements
