Novel device for fully utilizing remaining kinetic energy of ventilation air methane and use method of novel device

Abstract

The invention relates to the technical field of coal mine ventilation, and provides a novel device for fully utilizing remaining kinetic energy of ventilation air methane and a using method of the novel device. The device comprises a conveying pipeline, a wind driven generator and multiple one-way pressure sensing valves. Ventilation air methane is adjusted through the conveying pipeline to drive the wind driven generator to generate electricity. The conveying pipeline is composed of a front steady flow acceleration pipeline and a rear energy storage pipeline. A first flow stabilizing pipe, a first diffuser, a second flow stabilizing pipe and a flow collector are sequentially arranged in the front steady flow acceleration pipeline. A second diffuser, a third diffuser and a fourth diffuser are sequentially arranged in the rear energy storage pipeline, a pressure sensor, an intelligent instrument and a one-way pressure sensing valve are arranged in each of the second diffuser, the third diffuser and the fourth diffuser, and the multiple one-way pressure sensing valves are opened step by step to complete energy storage. The novel device for fully utilizing the remaining kinetic energy of the ventilation air methane and the using method of the novel device have the beneficial effects that the device can continuously convert ventilation air methane energy into electric energy to be used by other mine mechanical equipment, and the current situation of electric energy shortage at present can be relieved.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a novel device for making full use of residual kinetic energy of exhaust wind and a method for using the same. Background technique [0002] At present, mining methods include open-pit mining, underground mining and in-situ modified mining. my country's coal mine production is mainly based on underground mining. In my country, the underground mining method occupies a dominant position in coal mining, and the harmful gases that need to be discharged underground include: gas, carbon monoxide, dust and various harmful gases that are not conducive to human breathing, and are excavated for underground workers. The working surface provides sufficient fresh air to meet the needs of personnel breathing, gas dilution and heat dissipation of various equipment. To achieve the above requirements, the continuous work of the main ventilator in the coal mine is required to real...

Problems solved by technology

Some scholars have published about the utilization of kinetic energy in mine exhaust air, aiming to convert the kinetic energy of mine exhaust air through wind generators at the ventilator outlet into electric energy for daily electricity consumption in mines, but exhaust air is a highly mobile gas. It cannot be fully utilized during conversion, and there will inevitably be a certain amount of loss and waste, resulting in the waste of energy after the exhausted exhaust air is discharged, and the discharge of dirty air in the exhausted air will affect the environment.
