Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0017] As shown in the figure, the shock wave bubble rapid dust reduction device used in the blasting of this embodiment includes a water bag 1, and water 2 is installed in the water bag. The ratio of the volume of water to the volume of the water bag is 0.6-0.7. Carbon dioxide, or a chemical for generating carbon dioxide gas, is dissolved in the water, and a foaming agent for generating air bubbles is also dissolved in the water.

[0018] In this embodiment, the pressure range of the water bag is 0.5-0.6MP, and an air column bag made of high-quality PE+PA plastic film can be used. The diameter of a single branch bag is 10mm, and the length is 200mm. You can contact the manufacturer according to actual requirements Customized, adjust the number of branch bags according to the diameter of the blast hole when using; the chemical substances used to generat...

Abstract

The invention discloses a shock wave bubble rapid dust fall device used in blasting. The shock wave bubble rapid dust fall device used in blasting comprises a water bag, the water bag is filled with water, the ratio of the volume of the water to the volume of the water bag is 0.6 to 0.7, carbon dioxide or chemical substances used for generating carbon dioxide gas is dissolved in the water, and a foaming agent used for generating bubbles is further dissolved in the water. According to the shock wave bubble rapid dust fall device used in blasting, a large amount of fine bubbles and water mist can be generated during blasting, the fine bubbles and the water mist can uniformly diffuse around, the standing time of the fine bubbles and the water mist is longer, the capacity of capturing dust ishigh, and the dust fall effect is good.

Description

technical field [0001] The invention relates to the technical field of blasting, in particular to a blasting device capable of rapidly reducing dust. Background technique [0002] At present, in domestic tunnel blasting, water-sealed blasting technology is generally adopted to control dust concentration and harmful gas emissions from the source. The definition of water seal blasting by relevant domestic scholars is: use plastic water bags filled with clear water to be placed on the front and rear of the explosive, and the orifice water bag is used instead of solid gun mud. After the explosive explodes, the water in the water bag becomes Water vapor and fine water droplets suspended in the air can capture dust and absorb harmful gases, thereby reducing the concentration of dust and harmful gases. [0003] On-site practice has proved that the water-sealed blasting technology has played a certain role in reducing dust and absorbing harmful gases during the tunnel excavation an...
