[0033] Specifically, the working principle of the water coal gas waste boiler by-product steam recycling device is as follows: in use, as the temperature and pressure of the shift system gradually rise, the pressure of the water coal gas waste boiler body 1 also rises, the first steam pipeline 27 is specifically a 2.5 MPa steam pipeline, the second steam pipeline 210 is specifically a 1.0 MPa steam pipeline, and the synthetic steam pipeline 211 is specifically a 2.5 MPa steam pipeline. Before entering the first steam pipeline 27, the front hand valve 25 on the first pipeline 22 is in an open state, the rear hand valve 26 is in a closed state, and the steam stop valve 28 on the first steam pipeline 27 is opened. When the pressure of the water coal gas waste boiler body 1 is higher than the pressure of the first steam pipeline 27, the pressure regulating valve 24 on the first pipeline 22 is opened, so that the by-product steam smoothly enters the pipe network through the first steam pipeline 27, thereby realizing effective control of the pressure of the water coal gas waste boiler body 1. The first steam pipeline 27 is connected with an external steam recycling system, and the steam stop valve 28 and the front hand valve 25, the pressure regulating valve 24, and the rear hand valve 26 jointly act to flexibly control the on-off and pressure regulation of steam. Before being sent to the synthetic steam pipeline network, the front hand valve 25 on the second pipeline 23 is in an open state, the rear hand valve 26 is in a closed state, and the steam hand valve is in an open state. When the pressure of the water coal gas waste boiler body 1 is higher than the operating pressure, the pressure regulating valve 24 on the second pipeline 23 is opened, so that the steam is sent to the 2.5 MPa steam pipeline network of the synthesis device through the synthetic steam pipeline 211 via the steam hand valve and the check valve. The synthetic steam hand valve 212 on the synthetic steam pipeline 211 can manually adjust the steam flow, and the check valve prevents the backflow of steam to ensure the flow of steam in the specified direction. The trap 29 can timely drain the condensed water in the pipeline to avoid the accumulation of condensed water affecting the efficiency and quality of steam transportation. Since the drainage end of the trap 29 is connected with the water inlet end of the drainage shell 31, the condensed water discharged from the trap 29 can smoothly flow into the drainage shell 31, realizing the centralized collection and treatment of the condensed water. The liquid level sensor 32 and the servo motor 310 can be electrically connected through the control panel. The liquid level sensor 32 can monitor the liquid level of the condensed water in the drainage shell 31 in real time and transmit the liquid level data to the control panel.

Since the worm wheel 38 is sleeved outside one of the shafts 33, the rotation of the shaft 33 is realized, and in turn the rotation block 34 rotates in the interior of the drainage shell 31, so that the drainage plug 36 is aligned with the drainage port of the drainage shell 31 and realizes the drainage function under the action of the drainage holes on the drainage plug 36.
