What is CO2 blasting equipment?
With the continuous development of modern industry, blasting engineering is more and more widely used in various fields. As a new type of blasting technology, carbon dioxide blasting equipment has also received more and more attention. So, what exactly is carbon dioxide blasting equipment?
Carbon dioxide blasting equipment is a device that uses liquid carbon dioxide as the medium and uses the energy generated by its phase change process to blast. This equipment injects liquid carbon dioxide into explosives or rock mass, and by controlling changes in pressure and temperature, the carbon dioxide is vaporized instantaneously, resulting in a large amount of high-pressure gas that pushes the rock or material to blast.
CO2 blasting equipment offers a number of advantages over conventional blasting technology. First of all, it does not generate sparks and high temperatures, so it has greater safety. Secondly, because carbon dioxide is an environmentally friendly gas, no harmful gases are produced during the blasting process, and the impact on the environment is small. In addition, carbon dioxide blasting equipment is simple to operate and low cost, and can be widely used in various blasting projects.
The principle of carbon dioxide blasting equipment is based on the principle that liquid carbon dioxide is rapidly vaporized under pressure to produce a large amount of high-pressure gas. When liquid carbon dioxide is injected into explosives or rock mass, the pressure rises rapidly, causing the carbon dioxide to vaporize instantaneously, creating a strong impact and pressure that pushes the rock or material to blast. At the same time, due to the high expansion coefficient of carbon dioxide gas, a larger free surface can be formed during the blasting process, which can improve the blasting effect.
Carbon dioxide blasting equipment has a wide range of applications, and can be used in mining, water conservancy and hydropower engineering, tunnel construction, municipal engineering and other fields. In mining, carbon dioxide blasting equipment can be used for the loosening and transportation of ore;In water conservancy and hydropower projects, it can be used for loosening and excavation of dam bodies;In tunnel construction, it can be used for tunnel excavation and penetration;In municipal engineering, it can be used for pavement crushing and excavation, etc.
In short, carbon dioxide blasting equipment is a new type of blasting technology, which has the advantages of high safety, environmental protection and low cost. Its application will bring more convenience and benefits to engineering construction in various fields.
