Abstract: A system for extracting carbon source from sewage sludge in sewer pipes through online organic and inorganic component separation includes an outer system box, where the outer system box is provided therein with a system body; the system body includes a deodorization module, a pre-treatment module, and a cyclone separation module that are sequentially connected from top to bottom; an upper side wall of the cyclone separation module is provided with an oversize residue pressing module; and the pre-treatment module, the cyclone separation module, and the oversize residue pressing module are electrically connected to a control module. The present disclosure achieves online and on-site quick treatment of the sewage sludge in the sewer pipe, and solves common practical problems arising in the existing centralized treatment and disposal method of sewage sludge in the sewer pipe.

Abstract: The present application provides a control device for controlling a switching converting module to generate an output signal of constant output current from a rectified AC power supply signal. The switching converting module comprises a primary winding for receiving the rectified AC power supply signal and a power switch coupled in series with the primary winding.
