Efficient tail gas particle purification system of mining rubber-tyred vehicle

Abstract

The invention belongs to the technical field of tail gas emission of transportation equipment of mining rubber-tyred vehicles for underground coal mines and particularly relates to an efficient tail gas particle purification system of a mining rubber-tyred vehicle. The efficient tail gas particle purification system solves the problem that in the running process of existing mining rubber-tyred vehicles for underground coal mines, tail gas particle emission performance exceeds standards seriously. The efficient tail gas particle purification system of the mining rubber-tyred vehicle comprises an exhaust pipe and an exhaust tail pipe and further comprises a tail gas particle purification device and a display and warning system, the tail gas particle purification device comprises an exhaust safety device and a tail gas particle catcher arranged between the exhaust pipe and the exhaust tail pipe, the tail gas particle catcher comprises multiple levels of catcher bodies arranged in a shell in sequence, the catcher body of each level is formed by stacking a plurality of metal foam sheets, the metal foam sheets are made of Fe-Cr-Al in a firing mode, have different hole diameters and have the thicknesses of 3 mm-5 mm, and the hole diameters of the metal foam sheets in the levels of catcher bodies gradually decrease.

Description

technical field [0001] The invention belongs to the technical field of tail gas emission of transportation equipment of rubber-tyred vehicles used in underground coal mines, and in particular relates to a high-efficiency tail gas particle purification system of rubber-wheeled vehicles used in mines. Background technique [0002] The present invention mainly solves the problem that the emission of soot particles from the engine exhaust of rubber-tyred vehicles used in underground mines in coal mines is seriously exceeding the standard; to adopt the particle catchers used in ground vehicles, a renewable system must be added, but it is strictly forbidden to use open flames underground and the surface temperature is higher than 150°C, so it is impossible to install a regeneration system, resulting in serious blockage and poor purification efficiency of the traditional particle trap. This system can effectively solve the problem of particle trap blockage and low purification effic...

Problems solved by technology

[0003] The present invention solves the problem that the discharge performance of exhaust particulate matter seriously exceeds the standard during the operation of existing rubber-tyred vehicles used in underground coal mines, and the underground is in a relatively closed space, which increases the probability of lung disease among underground miners; it improves the purification efficiency and prolongs particle capture. According to the regeneration cycle and life of the trap, it provides a mining rubber-tyred vehicle exhaust particle purification system; after the adsorption of sediment will block the trap, it will play a role in displaying and alarming the driver
