Embodiment Construction

[0026] Below in conjunction with accompanying drawing and specific embodiment the present invention will be described in further detail:

[0027] The coal mine dust removal device based on ultrasonic atomization and condensation shown in the figure includes a negative pressure pipeline formed by a blower 101, a vacuum pump 113 and connecting pipes, and a cyclone separator 102 and an ultrasonic atomizer 103 are arranged in sequence on the negative pressure pipeline. , pressure valve 106, coagulation chamber 108, cyclone separator 102 is connected with air blower 101, vacuum pump 113 is also connected with dust collector 114, wherein, ultrasonic oscillator 107 is arranged in coagulation chamber 108, and sound-absorbing chamber 108 outlet is also provided with Sponge 110. The sound-absorbing sponge 110 absorbs the residual sound waves passing through the dust gas, forming traveling waves in the cavity, preventing the sound waves from being reflected and interfering with the forma...

Abstract

The invention discloses a coal mine dust-removing device based on ultrasonic atomization and condensation. The coal mine dust-removing device comprises a negative pressure pipeline composed of an airblower, a vacuum pump and a connecting pipeline. The negative pressure pipeline is provided with a cyclone separator, an ultrasonic atomizer, a pressure valve and a condensation chamber sequentially.The cyclone separator is connected with the air blower. The vacuum pump is further connected with a dust collector. The condensation chamber is internally provided with an ultrasonic oscillator. A sound absorption sponge is further arranged at an outlet of the condensation chamber. The coal mine dust-removing device is easy to implement and high in efficiency, the content of coal dust in air in acoal mine roadway is effectively decreased, vicious accidents such as coal dust explosion are avoided, and safe conducting of the coal mine roadway exploiting process is ensured.

Description

technical field [0001] The invention relates to the field of coal mine mining, in particular to a coal mine dust removal device based on ultrasonic atomization and condensation, which is applied in the excavation process of coal mine roadways. Background technique [0002] The coal industry is the basic industry of our country's national economy, and focusing on coal is the basic strategy of our country's energy security. The coal industry supports the sustained and rapid development of the national economy. However, my country's coal mines have not yet achieved effective control of disasters and accidents. Taking the hazards of coal mine dust as an example, in the process of coal mining, such as drilling, blasting, tunneling and coal mining operations, roof management, coal loading and transportation, etc., A lot of dust will be generated. Coal mine dust (hereinafter referred to as coal dust) generally refers to the fine solid aggregates produced during mineral mining or p...
