Abstract

An engine exhaust pipe is connected to one side of the top end of a loader, a heater pipe fixedly sleeves the top end of the engine exhaust pipe, one end of the heater pipe is connected to one side of an electric heating box, and a through hole is formed in one side of the top end of the electric heating box; one side of the electric heating box is connected with a purification box pipe, one end of the purification box pipe is connected to one side of the purification box, the top end of the purification box is provided with a purification box exhaust pipe, the top end of the loader is provided with a controller through screws, and the position, close to the controller, of the top end of the loader is provided with a storage battery through screws. The honeycomb heater is installed in the electric heating box through screws, tail gas is exhausted into the purification box to be further purified and then exhausted into the atmosphere after being fully combusted in the electric heating box through the honeycomb heater, tunnel air pollution is reduced, the construction environment is maintained, and the body health of constructors is guaranteed.

Description

technical field [0001] The invention relates to a purification device, in particular to a tail gas purification device based on electric heating for tunnel construction machinery. Background technique [0002] In railway and highway construction, tunnel construction occupies a considerable proportion. Tunnel engineering will produce pollution during the construction process. The pollution sources mainly include harmful gases emitted by construction machinery powered by internal combustion engines and smoke generated by blasting. Due to the long operation time of construction machinery, it has become the main pollution source of tunnel construction pollution. Tunnel construction machinery It belongs to non-road mobile machinery, and the state has corresponding emission standards, so the non-road mobile machinery is installed with a post-processing system when it leaves the factory to meet the non-road emission standards. [0003] However, at present, the oxygen concentration...
