1. The system adopts multi-point control, pre-treatment crushing will produce a lot of dust and noise in the production process. Design in the crushing link. Noise reduction room and negative pressure dust removal measures. Due to the high energy consumption of the crusher, the instantaneous starting current is larger, and the current and voltage as well as the equipment operating temperature. Real-time monitoring, System such as the normal operation of the card machine or other faults can also be displayed in the DCS alarm emergency stop. All the preprocessing in the system .The equipment conditions are displayed in the DCS, and the problems that will occur can be predicted according to the data.
2. The pre-treated material is sent to the bin through the conveying device. The storage bin designed by HaiQi can store the amount for 5-6 hours, and the material can be stored according to the material level. The sensor automatically stops the front-end preprocessing operation, and the preprocessing system automatically starts when the material level falls below the low material level.

1. Before the pre-treated biomass is sent to the dryer through the conveying device, HaiQi Dcs system will send the material to the dryer according to the startup temperature of the system.T he dryer. Dryer thermal pipe design temperature and pressure difference sensor and temperature sensing automatic electromagnetic valve, according to the residual heat temperature of high and low temperature sense. The automatic solenoid valve opens automatically to prevent the risk of fire in the high temperature dryer.
2. The temperature regulating valve can automatically adjust the size according to the demand of raw materials. in case of emergency power failure, the valve will be fully opened to avoid the occurrence of fire.

1. The dried material enters the pyrolysis system through the wind shelter valve, and enters the system. The DCS of Haiqi will follow the temperature of the system segment. Pressure, adjust the feeding amount of the system and the residence time of the material to confirm the safe and stable operation of the system.
2. The back-end of the pyrolysis system is equipped with pressure relief valve and explosion-proof water seal, which can effectively inhibit the emergency power failure and the shutdown under special conditions.

1. The combustible gas after the operation of the pyrolysis system is transported to the burner through the gas pipeline, and passes through the 6-level two-way safety valve (natural gas standard) before the burner. Emergency closure in the case of power failure within 1-1.2s, the gas will be switched to the safety release torch. Where you can monitor the flow of gas, the velocity,Temperature, and pressure difference. Proceed to the next step based on the system running data.
2. Low-NOx combustion system, through the control of combustion temperature can inhibit NOX generation, HaiQi real-time detection of combustion temperature and pressure. The stability of operation can be judged by observing the pressure difference and temperature.

If the actual user needs energy, HaiQi can be configured with gas steam boiler, combustible gas through the burner to the high temperature section1300-1500 Heat transfer in the gas steam boiler, can effectively use the heat of the high temperature section. HaiQi designs special biomass gas-fired boilers. Wood tar and wood vinegar in gas can be effectively converted into physical and chemical combustion heat.
DCS can detect the gas production condition, pressure and temperature of the boiler in real time.

The tail of the boiler is installed, and the flue gas and another heat exchange medium are exchanged in the flue gas during heat exchange, After the low temperature medium absorbs a lot of heat energy,it is returned to the boiler again, which is equivalent to the secondary utilization of waste heat, thereby improving the performance of steam equipment and reducing energy consumption.

HaiQi allocates suitable dry dust collector according to the actual emission requirements of the project site. Generally. cloth bag dust removal is adopted. Temperature and humidity have greater requirements, HaiQi designed a temperature sensing automatic valve in the bag dust pipe, which can be based on the temperature and humidity of the tail gas. Open the adjustment to prevent high/low temperature exhaust gas into the bag dust caused by failure.2. The fault of the general dust collector is caused by the delay in judging the exhaust gas temperature. HaiQi strictly controls the temperature, pressure and humidity of the exhaust gas in real time to avoid. Hidden danger of safe operation due to inaccurate human monitoring.

At the beginning of the system design, the earliest consideration is the safety of the system operation. The pyrolysis system is a single-channel rotary kiln with large volume, more biomass materials and combustible gases during operation, which has a huge risk of fire, explosion, and CO exposure  for operators.
In the generation section of biomass gas, HaiQi began to adopt multi-point monitoring, pressure relief monitoring of combustible gas, emergency exhaust detection and control of combustible gas, concentration alarm of combustible gas and emergency closure monitoring of combustible gas after power failure, etc.

HaiQi configures different CHP and CCHP multigeneration systems according to user requirements, Steam turbine and ORC can be configured according to user requirements, or steam and green electricity services can be provided according to the needs of thermal power production enterprises, Steam turbines are selected according to user requirements.
