Description

TECHNICAL FIELD

[0001] The utility model belongs to the coal gas recovery technical field, concretely relates to a pipe wall detachable elbow. BACKGROUND

[0002] When the coal gas is recovered from the coal cold tower electrostatic precipitator, the temperature of the recovered coal gas is relatively high, so the coal gas needs to be cooled by spraying water. The specific structure of the spray pipeline is shown in the figure Figure 1 , a water pump 3 arranged on the spray main pipeline 2 draws spray water from the water source 1 at the bottom end and then conveys it to each branch spray pipeline. However, since the height of the top spray pipeline 4 is relatively high, the pressure of the spray water reaching the top layer cannot meet the use requirements. In addition, the spray main pipeline 2 is connected with the top spray pipeline 4 through an elbow 5, and the spray water entering the top spray pipeline 4 from the spray main pipeline 2 is further reduced in water pressure due to the effect of the pipeline force, so that impurities in the spray water are easily accumulated at the elbow 5, and the top spray pipeline 4 is blocked after a long time, resulting in poor cooling effect of the top spray pipeline 4 on the coal gas and causing energy loss. In order to ensure the cooling effect, the blockage needs to be cleaned regularly, and the elbow 5 needs to be cleaned after the top spray pipeline 4 is completely removed. Since the length and height of the top spray pipeline 4 are too long and high, the workload of the staff is huge, time-consuming and labor-intensive, and there is a certain safety hazard.

[0019] The utility model will be further explained in detail in combination with examples as follows:

[0020] When recovering the coal gas by the coal cold tower electrostatic precipitation, the temperature of the recovered coal gas is relatively high, and the coal gas needs to be cooled by spraying water. Figure 1 As shown in the specific structure of the spraying pipeline, Figure 1 The water pump 3 arranged on the spraying main pipeline 2 extracts the spraying water from the water source 1 at the bottom end and then delivers the spraying water to each branch spraying pipeline. However, as the height of the top spraying pipeline 4 is relatively high, the pressure of the spraying water reaching the top layer cannot meet the use requirement. In addition, the spraying main pipeline 2 is connected with the top spraying pipeline 4 through the elbow 5, and the water pressure of the spraying water entering the top spraying pipeline 4 from the spraying main pipeline 2 is further reduced due to the force of the pipeline, so that the impurities in the spraying water are easily accumulated at the elbow 5, and the top spraying pipeline 4 is blocked after a long time, which results in poor cooling effect of the top spraying pipeline 4 on the coal gas and causes energy loss. In order to ensure the cooling effect, the blockage needs to be cleaned regularly, and the elbow 5 needs to be cleaned after the top spraying pipeline 4 is completely removed during the cleaning. As the length and height of the top spraying pipeline 4 are too long, the workload of the workers is huge, time-consuming and labor-intensive, and there is a certain safety hazard.
