2results about How to "Large adjustment ratio" patented technology

The utility model discloses a premixer with a high regulation ratio and an energy-saving environment-friendly water heater, the premixer comprises a shell, an air inlet, an air adjustable inlet channel, an air straight-through inlet channel, a premixing cavity, a fuel gas inlet and a regulation baffle plate, the air adjustable inlet channel is provided with a fuel gas inlet channel, and the air straight-through inlet channel is provided with an adjusting baffle plate; the fuel gas inlet channel is provided with a fuel gas inlet adjusting opening facing an opening of the premixing cavity, and the adjusting baffle is used for adjusting the gas circulation area of the air adjustable inlet channel and the fuel gas inlet adjusting opening. According to the premixer, the air adjustable inlet channel, the air straight-through inlet channel, the fuel gas inlet channel, the premixing cavity and the like are improved, and the adjusting baffle is used in cooperation, so that the adjusting baffle can dynamically adjust the air inflow of air and fuel gas along with the pressure difference change in the cavity, premixing is conducted in the premixing cavity, and the air and fuel gas mixing efficiency is improved. The water heater can adopt a more reasonable combustion proportion, the adjustment ratio of soft fire is wider, the water heater can adapt to different air sources, temperature control is more accurate, and bathing is more comfortable in summer.

The utility model discloses a double fluid spray system, this double fluid spray system includes: pump station system and spray gun, and pump station system includes liquid path device, gas path device, control cabinet and spray system pump station, and liquid path device is connected spray system pump station through water inlet pipe, and gas path device is connected spray system pump station through air inlet pipe, and spray system pump station is connected with the water ring pipe and gas ring pipe among humidification device through water path pipeline and gas path pipeline, and humidification device still is installed heat resistance, and humidification device is humidification tower or humidification pipeline, and three heat resistances are arranged on humidification device, and eight spray guns are arranged on water ring pipe and gas ring pipe, and four are not controlled spray guns, and four are the spray gun of being controlled in group. Through the work of eight spray guns, four are not controlled spray guns, and four are controlled spray guns, have the advantage that the working condition is adjusted flexibly, and the adjustment ratio is big, and atomization quality is high, and the demand of system is satisfied.
