Not only does it not meet the purpose of environmental protection in my country, but it also fails to meet the requirements of green construction, and may cause damage to the health of nearby residents and construction workers.
Nowadays, the prevention and control methods for blasting smoke and dust are mainly large-scale dust-proof nets, setting up high-pressure pipe network spraying water, etc. In summary, they are poor in effect, low in efficiency, and uneconomical and practical.

Embodiment
[0021] In the blasting and demolition of a building, the water inlet cover 14 is unscrewed, and an appropriate amount of water is filled into the water storage bag 13. In the stage of detonation network connection, several devices are placed on columns, shear walls, and floors containing blast holes. For beams and other locations where smoke and dust are likely to be generated, insert the nonel into the nonel insertion channel 1, and use the cross to connect to the detonation network together. In this way, while detonating, the detonator ignites the gas generating agent 5, and its reaction chemical equation is: 8CH 3 N 5 +7KClO 4 =7KCl+8CO 2 +12H 2 O+20N 2 , the gas generating agent 5 reacts rapidly after being ignited to generate carbon dioxide, water vapor and nitrogen. Under standard conditions, 1 g of the gas generating agent produces about 0.542 L of gas, which is instantly filled into the elastic air storage bag 11 and stored under the action of expansion. The water...

Abstract
The invention relates to a blasting dust fall air bag watering device, which specifically comprises a gas production system, a gas storage system and a water spraying system, wherein the gas production system comprises a detonating tube insertion channel, bayonet rubber, an iron shell, sealing paper, a gas production agent (a mixture of pentaaminotetrazole and potassium perchlorate), a metal knitted filter screen, vent holes and a heat insulation net, the gas storage system comprises a temporary gas storage chamber, a one-way vent valve and an elastic gas storage bag, and the water spraying system comprises a water storage bag, a water inlet cover and a one-way drainage valve (a water inlet hole, a spring, a sealing rubber ring, a sealing rubber ring supporting plate, a water spraying hole, a water outlet hole, a one-way drainage chamber and a plastic shell). According to the invention, the device can be connected into a detonating network, placed at a key position where smoke dust may be generated, and detonated together with the detonating network, so that the purposes of synchronous dust falling and fixed-point dust falling are achieved while the smoke dust is generated; and water in the water storage bag is sprayed out through the expansion effect of the internal elastic gas storage bag, so that the dust falling effect can be effectively improved, and the dust falling area is increased.
Description
technical field [0001] The invention relates to the field of blasting construction, in particular to a blasting dust suppression sprinkler device. Background technique [0002] In modern blasting engineering, the prevention and control of post-blast hazard effects is very important. Among a series of harmful effects of blasting, such as smoke, vibration, shock wave, flying stones, etc., blasting smoke is more harmful and more difficult to control. Not only does it not meet the purpose of environmental protection in my country, but it also fails to meet the requirements of green construction, and may cause damage to the health of nearby residents and construction workers. Nowadays, the prevention and control methods for blasting smoke and dust are mainly large-scale dust-proof nets, setting up high-pressure pipe network spraying water, etc., which are poor in effect, low in efficiency, and uneconomical and practical. Therefore, how to efficiently and economically achieve th...
