The invention discloses a mine explosion-proof
diesel engine tail gas purification device and method. The device includes a purification chamber, a
metal filter element, a spherical bottom cover, a purification cylinder and legs, and the purification chamber is provided with a particulate matter
trapping chamber and a particle collection chamber. The
metal baffle of the gas catalytic chamber, one side of the particulate matter
trapping chamber is provided with an air inlet, the side of the gas catalytic chamber is provided with an air outlet, the
metal filter element is disposed in the particulate matter
trapping chamber, the purification cylinder is disposed in the gas catalytic chamber, and the purification chamber There is a high-temperature and high-pressure manhole on the body, which is used to take and place the metal
filter element. The main advantages are as follows: 1) The metal filter element has large
dirt holding capacity and
low resistance; the surface is coated with PTFE
coating, which is easy to clean and overcomes the shortcomings of traditional filter elements that are difficult to clean; 2) Utilizes the reducing and oxidizing hazards in the
exhaust gas According to the characteristics of the coexistence of substances,
transition metal oxide catalysts are prepared to eliminate "harms"; 3) avoiding the use of external reducing agents such as
urea and
electrical equipment, and simplifying the device structure.
