Novel purifier capable of generating power by utilizing temperature difference of automobile waste gas

The invention discloses a novel purifier capable of generating power by utilizing temperature difference of automobile waste gas. The novel purifier capable of generating power by utilizing temperature difference of automobile waste gas comprises an exhaust pipe, a temperature difference power generation sheet, a connection sleeve, an outer shell, a baffle tile, a flow guiding head, a middle shell, large-hole size particle arresters, large-hole size net-shaped adsorption bodies, an inner shell, small-hole size particle arresters, small-hole size net-shaped adsorption bodies, a storage battery, a gas inlet pressure sensor, a gas outlet pressure sensor, an exhaust fan and a control. The novel purifier has the beneficial effects that a Z-shaped waste gas passage is manufactured by using the outer shell, the middle shell, the inner shell and the baffle tile; automobile waste gas uniformly enters the passage between the outer shell and the middle shell under the action of the flow guiding head; the waste gas is fi
