Abstract: A incinerator comprises a framework, a liquid-vapor tank, a plurality of liquid tanks, and at least two fluid dryer tanks. The framework provides a plurality of elongated horizontal frames fixedly attached to a front and a rear walls thereof respectively. The liquid-vapor tank strides the framework and occupies a top area thereof. The liquid tanks each are disposed under the liquid-vapor tank and occupy a space confined by two neighboring horizontal frames respectively. The fluid dryer tanks each are disposed below the liquid tanks. The liquid from the liquid source may enter the liquid tanks and the liquid-vapor tank and a specific water level may be maintained constantly. The vapor can move outward from the vapor discharge pipes and is collected for further use and the dense fluid can be filled into the fluid dryer tanks and is dried up slowly and to be recycled for the energy saving and the environment protection.

Abstract: An exhaust pipe assembly is composed of a circuitous filter route surrounded by a cooling water container for treating the exhaust out of an internal combustion engine, permitting the exhaust to be cooled down, the noise generated to be muffled, and solid particles containing in the exhaust to be removed. The exhaust pipe assembly may be cleaned by the cleaner for exhaust pipe disclosed in U.S. Pat. No. 5,074,007.

Abstract: A filter system for smoke or polluted air comprises a smoke or polluted air filter device, a bag filter device, and a water treatment device. A duct and a plurality of power sprayers are provided in the smoke or polluted air filter device to remove harmful substances in the smoke or the polluted air. A plurality of filtering bags are provided in the bag filter device to clean the waste liquid coming from the smoke or polluted air filter device. A plurality of treating troughs are provided in the water treatment device to purify the liquid flowing down from the filter bag device. A coarse ash collecting device is provided additionally in the filter system to collect particle ashes or dusts in the smoke before entering the smoke or polluted air filter device. Ingredients such as carbon ashes, grease or oily substances, offensive odors, poisonous substances, and etc. contained in the smoke or the polluted air may be suitably treated by the filter system.

Abstract: A cleaner for an exhaust pipe comprises a main housing, a power means, a dirt suction means, a flexible suction pipe, a flexible wire spindle, a discharge sleeve, and a porous container. The power means and the dirt suction means are installed in the main housing. A connecting element connects the suction means chamber to a suction pipe. At the bottom of the suction means chamber are located a discharge sleeve and a porous container. A flexible wire spindle is provided at the free end with a discharge sleeve and a porous container. A flexible wire spindle is provided with a brush at the end opposite to the power means. When the flexible wire spindle and the flexible suction pipe are inserted into an exhaust pipe and the power means started, the cleaner may clean off and suck out the dirt accumulated in the exhaust pipe handily and swiftly.
