With the rapid development of science and technology, the use of breeding hot blast stoves is becoming more and more common. In order to facilitate user use and management, automatic control devices are installed on the hot blast stoves. The control unit can realize the following functions:
The ratio of air to gas is automatically adjusted, and electric regulating valves and flow holes are installed in the air and gas pipes, respectively. The air-fuel ratio is controlled by the PID adjustment, and the air-fuel ratio is reset according to the change of the gas.
The temperature of the cultured hot blast stove and the temperature of the hot air are automatically detected. Thermocouples are arranged on the hearth and outlet pipes of the hot blast stove to realize the detection of the temperature of the hearth and the temperature of the hot air. In addition, according to user requirements, the hot air temperature can also be adjusted automatically. The principle is to feed the hot air signal to the PLC, and then the PLC adjusts and controls the flow of air and gas according to the signal and the furnace temperature.
The electric windshield secondary air duct is provided with an electric shutter control valve, which can control and adjust the secondary air flow according to the setting program (according to the valve opening degree). Set the principle of the control program. When the hot air duct temperature is lower than the required temperature, the PLC sends a signal to increase the gas flow and the combustion air flow. At the same time, the secondary air reduces the secondary air flow through the electric regulating valve of the secondary air duct. When the outlet temperature of the hot air duct furnace is higher than the required temperature, the PLC sends a signal to reduce the gas flow rate and the combustion air flow rate, and at the same time adjusts the electricity, and the throttle valve increases the secondary air flow rate.
The above is the introduction of the breeding hot air stove, I hope you can have a new understanding after watching. Qingzhou Mukang Machinery Co., Ltd. has many years of production experience, the quality of the equipment produced is reasonable, the price is reasonable, the after-sales service is perfect, welcome new and old customers to visit the company and negotiate cooperation, we will wholeheartedly ask you for your service, let you buy with confidence, use Have a good time.
