Further, the method comprises the following steps: the extraction pipeline is connected with the grain slag discharge device through a flange.

The utility model has the advantages that: and the gas with water and slag is extracted by the extraction pipeline under negative pressure. When the gas is pumped to the grain slag discharging device, the grain slag falls into the grain slag containing cavity to be collected due to the self gravity and the blocking effect of the partition plate; because the grain slag containing cavity is low in position, the internal grain slag is not continuously pumped out along with the gas. When the water granulated slag is collected to a certain amount, the water granulated slag can be discharged by opening the discharge port cover, and the water granulated slag discharge device can be continuously used by covering the discharge port cover. The utility model discloses can realize taking out gas, water separation and arrange the sediment function in the pipeline of taking out and adopt, reduce and take out ponding in the pipeline of taking out and adopt, get rid of the cinder in taking out and adopt the pipeline, improve the negative pressure of taking out and adopting the pipeline to gas drainage efficiency has been improved.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the following detailed description.

As shown in fig. 1 and 2, the water slag discharging device of the gas extraction pipeline comprises an extraction pipeline 1; the extraction pipeline 1 is provided with a grain slag discharging device 2; the grain slag discharging device 2 comprises a discharging device shell 2-1 and a discharging port cover 2-7; a partition plate 2-2 which is vertically arranged and has a distance with the bottom of a discharge device shell 2-1 is arranged in the discharge device shell 2-1, the inner space of the discharge device shell 2-1 at the two sides of the partition plate 2-2 is two gas passing cavities 2-3, the inner space of the discharge device shell 2-1 below the partition plate 2-2 is a granulated slag containing cavity 2-4, the discharge device shell 2-1 is provided with a granulated slag discharge port 2-6 and two communicating ports 2-5, the two communicating ports 2-5 respectively correspond to the two gas passing cavities 2-3, and the granulated slag discharge port 2-6 is positioned at the bottom of the granulated slag containing cavity 2-4; the extraction pipeline 1 is communicated with the communication ports 2-5; the discharge port cover 2-7 closes the granulated slag discharge port 2-6.

And gas with water and slag is extracted by negative pressure in the extraction pipeline 1. When the gas is pumped to the granulated slag discharging device 2, the granulated slag falls into the granulated slag containing cavity 2-4 to be collected due to the self gravity and the blocking effect of the partition plate; because the positions of the grain slag containing cavities 2-4 are low, the grain slag inside is not continuously pumped out along with the gas. When the granulated slag is collected to a certain amount, the granulated slag can be discharged by opening the discharge port cover 2-7, and the granulated slag discharge device 2 can be continuously used by covering the discharge port cover 2-7.
