Air purification device

Abstract

The invention discloses an air purification device, and relates to the technical field of mining engineering. According to the air purification device, through an air pump, air flows into a dust-removal device for purification, most dust remains in water, and the aim that the air is cooled through heat exchange between the air and the water is achieved; the air through a water storage space is high in humidity, a drying device and an outlet filter screen are arranged on an air outlet pipeline part, wet air is dried and dedusted again, and then the cool and dry air can return into an operationenvironment, so that the air-purification aim is achieved. By means of the air purification device, three functions of dust removal, cooling and air drying are integrated, the wet and dirty high-temperature air is transformed into the dry and clean low-temperature air, the work environment of downhole operation is effectively improved, the downhole air quality is improved, and therefore, the workefficiency is improved.

Description

technical field [0001] The invention relates to the technical field of mining engineering, in particular to an air purification device for dust removal, temperature reduction and dehumidification used in mines. Background technique [0002] With the continuous advancement of the industrialization process, the development speed, intensity and mining depth of the mining industry are increasing, and with the continuous improvement of the mining depth, the air quality and working environment under the mine are gradually deteriorating. [0003] First of all, the dust generated in mining operations is extremely harmful. Its existence not only leads to the deterioration of the production environment, aggravates the wear and tear of mechanical equipment, shortens the life of mechanical equipment, but more importantly, endangers the health of employees and causes various occupational diseases. Long-term inhalation of dust by the human body can cause respiratory inflammation in mild c...

Problems solved by technology

[0005] At present, the common measures to deal with the ground temperature are measures such as increasing ventilation and underground air conditioning. Underground air conditioners are generally large in size and difficult to move with the working surface. They are generally installed far away from the working surface. The working surface can only be reached after a long roadway, and the cooling effect is not good

Common measures to deal with dust include spray dust reduction, enhanced ventilation, and wet drilling. The wet dust removal method will further increase the humidity of the underground air and deteriorate the working environment; and dust removal by spray dust reduction and wet drilling. limited effect
