Abstract: A sludge processing equipment includes a separation set, a mixer, a blower and a heat recovery unit. The mixer includes a mixing chamber, a feeder and an air compressor. The mixing chamber is communicated with the separation set. The feeder is configured to deliver a sludge into the mixing chamber. The air compressor is configured to provide a first compressed air to the feeder. The air compressor generates a wasted heat during operation. The blower is configured to provide a transporting airflow to the mixing chamber, so as to deliver the sludge to the separation set. The heat recovery unit is configured to deliver the wasted heat generated by the air compressor to the transporting airflow.

Abstract: An aeration apparatus is provided. The aeration apparatus includes a raft, a cruising device, and an aeration device. The aeration device is installed on the raft. In use, the raft floats on a water surface, the cruising device propels the raft back and forth on the water surface, and the aeration device diffuses bubbles under the water surface.

Abstract: The methods and the apparatuses of an aeration equipment are described. A floatable aeration equipment with mobility at least has a floatable apparatus, a plurality of aeration apparatuses, and a controller. The thrust causing the motion of the aeration equipment is generated from the aeration apparatuses while aerating. The moving directions and positions of aeration equipment are controlled by a controller, which switches on/off a power source of one or more selected aeration apparatus.

Abstract: A fire and smoke control system for a long passage is utilized in a long passage with an inlet and an outlet. The fire and smoke control system for a long passage includes a first water spray curtain apparatus, a second water spray curtain apparatus, and at least one third water spray curtain apparatus. The first water spray curtain apparatus is fixed over the inlet, and the second water spray curtain apparatus is fixed over the outlet. The third water spray curtain apparatus is fixed on the top of the long passage between the inlet and the outlet to divide the long passage into several sections.

Abstract: A cruising aeration apparatus and a method are described. The cruising aeration apparatus comprises an aeration device for circulating the water in an aquatic pool, at least one conducting element connected to the aeration device for conducting the aeration device along a traveling route, and a controller. The at least one conducting element can be a rope or a float loop used as a separation line of a swimming pool. The pool water is drawn and pressurized by the aeration device and then ejected from nozzles of the aeration device. The nozzles on the front side and the rear side of the traveling route of the aeration device produce different counterforce. The aeration device is driven along the traveling route by the difference between the counterforce of the front side and the rear side of the traveling route. At least one switch is installed to control the opening and the closing of the nozzles, and is located on the side of the aeration device providing larger counterforce.

Abstract: An aeration method of a water pool and an apparatus thereof are disclosed, suitable for use in an aquatic pool or an aerobic processing pool. The aeration method requires placing at least one biofilter device in the water pool. An aeration apparatus comprises a pumping device and at least one projecting pipe connected to the pumping device. A plurality of nozzles is set on the projecting pipe. The pool water can be pumped into the projecting pipe by the pumping device, and the pool water pumped from the water pool is sprayed through the nozzles to the water pool and the biofilter device. The aeration apparatus may be a jet aeration apparatus or a wide-angle ejecting aeration apparatus.

Abstract: The present invention provides a high-pressure water sprayer for fire extinguishment, including a body having a base and a fluid conduit connecting thereto, and at least two spray heads and fluid-guiding bars respectively corresponding thereto. The base is provided with at least two positioning slots for positioning the spray heads. Each of the positioning slots communicates with a main fluid passage within the fluid conduit via a branched fluid passage. A nozzle is formed at a lower end of the spray head, and an orifice is formed at an upper end of the spray head for the fluid-guiding bar to be disposed in a receiving space within the spray head. Then the receiving space communicates with the nozzle. A lower end of the fluid-guiding bar is provided with fluid-guiding grooves opposite to the nozzle. The spray heads are arranged in at least two different disposed angles. An appropriate spray angle can be obtained by adjusting the angle between the nozzle and the base.
