Embodiment Construction
[0029] Embodiments of the present invention are described in detail below:
[0030] Such as figure 1 As shown, a control method for a fluidized bed gasifier system includes the control of the feeding system 10: the control system receives the material level in the rotary hopper 11 detected by the material level gauge installed on the rotary hopper 11 situation, when the raw material in the rotary silo 11 is lower than the set material level, the control system sequentially controls the start of the top feed screw 12, the start of the feeding elevator 13 and the opening of the top feed valve of the rotary silo 11 to start Automatic feeding state; when the raw material in the rotary silo 11 is higher than the set level, the control system sequentially controls the top feeding valve to close, the feeding elevator 13 to stop and the top feeding screw 12 to stop, and the feeding state is stopped. In this embodiment, the material level gauge may be an ultrasonic detector, a radar d...

The invention discloses a control method of a fluidized bed gasifier system. The method comprises the following steps: control on feed system: the control system receives the material level condition in a rotary storage bin detected by a material level indicator installed on the rotary storage bin; when the raw material in the rotary storage bin is lower than the set material level, the control system sequentially controls a bin top feed screw to start, a feed lifter to start and a bin top feed valve of the rotary storage bin to open, thereby starting the automatic feed state; and when the raw material in the rotary storage bin is higher than the set material level, the control system sequentially controls the bin top feed valve to close, the feed lifter to stop and the bin top feed screw to stop, thereby stopping the feed state. The control method of the fluidized bed gasifier system can implement automatic control on the feed system, and has the advantages of high control accuracy and high automatic control degree on the feed system, so that the feed system can operate stably, reliably and safely.
Description
technical field [0001] The invention relates to the technical field of raw material gasification, in particular to a control method for a fluidized bed gasification furnace system. Background technique [0002] Raw material gasification refers to the process of thermochemically processing the raw material with a gasification agent at a certain temperature and pressure to convert the organic matter in the raw material into gas. The fluidized bed gasifier system is a gasification system commonly used in industry. Traditionally, during the operation of the fluidized bed gasifier system, manual adjustment is generally adopted, and personnel with certain operating experience are required to operate. The operating status and parameters of the equipment need to be manually input into the computer and saved. The degree of automation control It is not high, and the accuracy of manual control is not easy to grasp, and the accuracy of regulation is not high. Contents of the inventio...
