In addition to the various hardware, software and hardware for sampling, monitoring and management, the most important part of the smoke monitoring system is the transmission of data from the data site to the management center. Extrusion Conical Twin Screw Barrel
Twin screw extrusion
Simply described, the twin-screw extruder is a machine consisting of two co-penetrating and self-cleaning identical screws which are mounted on shafts and rotate in the same direction in a fixed closed housing called [barrel" . The twin-screw extruders operate continuously with very short residence times.
The diameter of the screws in the conical twin-screw extruder is larger at the feed end and smaller at the die end.

In addition to the various hardware, software and hardware for sampling, monitoring and management, the most important part of the smoke monitoring system is the transmission of data from the data site to the management center. The system needs for communication networks:
1. The current data communication mode of the smoke gas online monitoring system to the management center is based on the data communication based on the TCP/IP protocol;
2. The accumulated data transmission volume is not large, but it is required that when the system sends and receives data, the transmission delay and packet loss rate should be as low as possible to ensure the timeliness of information reporting and control instructions issued;
3. The on-line smoke monitoring system will send control information to the equipment on the data site, such as monitoring equipment. To ensure the safe operation of the equipment, the system requires high security of the network and must be implemented through a special network and ensure The effective isolation from other networks to avoid accidents caused by cyber attacks;
4. There are many equipments that need to be monitored and managed in the on-line monitoring system of the flue gas, so the communication network must have enough network capacity to meet the increasing situation of monitoring points;
5. The investment in the communication transmission part should be small, the opening should be fast, the distribution is flexible, and the maintenance is simple.
Wireless load control, medium voltage carrier mode, Ethernet, SMS, and CDMA. The following is a comparison of these types of communication methods.
The parallel twin screw and the conical twin screw
According to whether the screw axis is parallel or not, the twin screws can be divided into the conical twin screw and the parallel twin screw, where the parallel twin screws are divided into fully intermeshing type, partly intermeshing type, non-engaged type, etc. In the case of parallel screws, the feed end and the die end have the same diameter.
