An automatic water release device for coal seam gas drainage

Abstract

The invention discloses an automatic water release device for coal seam gas extraction, which comprises a cylinder body, a movable sealing hatch is arranged at the lower part of the front of the cylinder body, water inlet pipes are symmetrically connected on both sides of the cylinder body, and the cylinder body The lower part of the right side is connected with a drainage pipe, the bottom of the cylinder body is movable and installed with a slag collection box, the middle part of the upper end of the cylinder body is provided with a vent hole, and the upper end of the cylinder body is welded with the vent hole A connected air outlet pipe, the top of the inner wall of the cylinder is inlaid with a first sealed bearing, the inner ring of the first sealed bearing is welded with a filter screen, and the lower part of the inner wall of the cylinder is inlaid with a second sealed bearing. The inner ring of the second sealed bearing is welded with an impeller, and the two sides of the lower end of the cylinder are symmetrically welded with brackets. The invention can realize the automatic separation of gas, liquid and solid, and can avoid clogging on the basis of ensuring the treatment effect, thereby being more convenient and practical.

Description

Technical field[0001]The present invention relates to the field of gas extraction, and in particular, a coal seam gas extract automatic water purifier.Background technique[0002]Gas is ancient plants in the early stage of accumulation of coal, and the cellulose and organic matter are decomposed by anaerobic bacteria. In high temperatures, high-pressure environments, gas is continuously generated due to physical and chemical effects while entering coal. Gas is colorless, odorless gas, but sometimes you can smell the scent similar to apple, because the aromatic hydrocarbon gas is simultaneously emerging. Gas is present in coal or surrounding rocks in a free state and absorbing state.[0003]At present, the use of coal seam gas extracts is extremely common. The product style is also a variety of products. This is due to the fact that different enterprises underground gas extracts are not exactly the same, but the pipeline arrangement is not close to the same, but most water reinforcers us...

AI Technical Summary

Problems solved by technology

[0003] At present, automatic water release devices for coal seam gas extraction are widely used, and the product styles are also varied. This is because the underground gas extraction processes of different companies are not exactly the same, and the pipeline layout is not nearly the same. However, most water release devices use inner cylinders or The buoy structure uses complex valves, and the above-mentioned structure cannot avoid valve and pipeline blockage, air leakage, water leakage, corrosion, etc., and the installation is complicated, slag removal is difficult, and it is difficult to meet the use requirements
