The invention belongs to the field of automobile engine energy saving, and particularly relates to an engine energy saving device and method for producing hydrogen through ultrasonic water mist and mineral particles, the device comprises a special water storage tank, an ultrasonic water mist generator and micro hydrogen production mineral particles, and the special water storage tank is divided into an ultrasonic water mist generation chamber and a mineral particle hydrogen production chamber through a permeation partition plate; the ultrasonic water mist generator is placed at the position 3 mm-5 mm below the liquid level of the ultrasonic water mist generating chamber, and water is atomized through external power supply. Micro-hydrogen production mineral particles are placed at the bottom of the mineral particle hydrogen production chamber and react with water to generate hydrogen, part of hydrogen is dissolved in water, and part of hydrogen is stored in the gas storage chamber above the liquid level. An air outlet is formed in the top of the special water storage tank and connected with an engine air inlet pipe, water mist and hydrogen enter an air cylinder along with engine suction to participate in acting, and therefore the redundant fuel injection amount is eliminated, and heat transfer loss in the cylinder is reduced. The heat efficiency of the automobile engine is improved, knocking is restrained, the incomplete combustion phenomenon is reduced, and then fuel consumption and harmful gas emission are reduced.

The invention belongs to the technical field of automatic water replenishing for boiler blow-off water tanks, and particularly relates to an automatic water replenishing device for a boiler blow-off water tank, which comprises a fixed tank, a first water inlet is fixedly connected to the upper surface of the fixed tank, a first water outlet is fixedly connected to the upper surface of the fixed tank, a second water inlet is formed in one side of the fixed tank, and a second water outlet is formed in the other side of the fixed tank. A first water outlet is formed in one side of the fixing box, a second water outlet is formed in the other side of the fixing box, a first cavity is formed in the fixing box, a fixing frame is fixedly connected to the interior of the fixing box, a second cavity is formed below the fixing frame, and a heat exchange assembly is arranged on the upper surface of the fixing box. And the heat exchange assembly comprises a plurality of positioning pipes fixedly connected to the lower surface of the fixing frame, the section of each positioning pipe is rectangular, a fixing groove is formed in each positioning pipe, and by arranging the stirring assembly and the heat exchange assembly, the problem that the sewage discharge well can be damaged by high-temperature sewage is solved.

This utility model provides a termite trapping and extermination device, belonging to the field of termite control technology. It includes a shell with a trapping structure installed on it. The trapping structure contains bait that attracts termites. The trapping structure includes a support plate with slots for placing pine wood. A rotating groove is also provided on the support plate, within which a cylinder rotates. Several entrance channels are provided on the outer wall of the shell, and several circular holes are provided on the outer wall of the cylinder. The entrance channels communicate with the circular holes. A collection box is detachably connected to the bottom of the shell. Through the trapping structure, the scent emitted by the pine wood, which has a strong attraction to termites, combined with the termite entry path designed for the shell and cylinder, effectively attracts termites into the trapping and extermination device, improving trapping efficiency.
