[0005] (2) The depth of research on existing governance measures is not enough
Take the widely used dust suppression method of sprinkling water as an example: everyone knows that sprinkling water can suppress dust, but they don’t know anything about the mechanism of dust suppression by sprinkling water, the water absorption characteristics of the object to be exploded, and the relationship between the water content of the object to be exploded and the amount of dust produced.
[0006] (3) Single governance measures
However, in this patent, key parameters such as the type of container to be used, the size of the container, the amount of explosives, the relationship between the water fogging time and the dust generation time are not clearly stated.

Embodiment 1

[0054] Fill each plastic water bag with 2.0kg of water, add 100g of fatty alcohol sodium sulfate, and put in 15g of domestic E1 series anti-water emulsifier roll-packed explosives (the diameter of the roll is generally 30-36mm). It can be purchased conveniently in my country's explosives monopoly market; then, before blasting, the water bag is hoisted in each floor space of the building to be demolished, and the water bag is arranged at a height of 1.5m from the ground. The distance between them is 1.5m, and they are distributed horizontally at equal intervals; the explosives in each water bag are detonated simultaneously with the adjacent broken blast holes with one No. 8 detonator.

Embodiment 2

[0056] Fill each plastic water bag with 2.5kg of water, add 100g of sodium dodecylbenzene sulfonate to it, and put 30g of domestic SB series water-resistant emulsifier roll-packed explosives (the diameter of the roll is generally 30-36mm) , this kind of explosives can be easily purchased in my country's explosives monopoly market; then before blasting, the water bags are hoisted in each floor space of the building to be demolished, and the height of the water bags is 1.5m from the ground. The distance between them and the water bag is 2m, and they are distributed horizontally at equal intervals; each section of explosive (each section of explosive 25g) in each water bag is detonated simultaneously with a No. 8 detonator and the adjacent broken blast hole.

Abstract

The dust falling active water mist method includes the following steps: setting surfactant and explosive in water bags, hoisting the water bags and distributing them homogeneously, and detonating the water bags through detonators to form water mist capturing dust. The method is used during blasting building to generate active water mist for falling dust.

Description

technical field [0001] The invention relates to a method for reducing dust by using active water mist and its application in the field of building blasting demolition. Background technique [0002] With the progress of society and the development of urban construction, the amount of demolition of old urban buildings in our country is increasing year by year, and the use of blasting demolition in urban development is increasing. However, the five major public hazards caused by blasting demolition, namely flying stones, vibration, noise, blast wind and dust, have made many people talk about "explosion". The dust generated during blasting demolition is intuitive and visible. Among the five major public hazards, people hate the dust generated by blasting demolition. In order to reduce the dust during blasting demolition, people have thought of many ways in recent years, and some results have been received. However, due to the lack of systematic research on dust control, the du...
