Basic structure of working principle of fresh air exchange machine The fresh air exchange machine is mainly composed of heat exchange system, power system, filtration system, control system, noise reduction system and box body.1. at present, the heat exchange system,At home or abroad,The heat exchanger used on the fresh air exchange machine has two forms of static and rotation, and the runner heat exchanger also belongs to the rotary type.From the perspective of normal use and maintenance,Static type is better than rotary type,But for mainframes larger than 2x10000m3/h,Generally, it can only be realized by the runner heat exchanger,Therefore, it can be said that both static and rotary have their own advantages and disadvantages.In order to easily arrange the air flow passage in the equipment,To reduce the volume of the whole machine,The fresh air exchange machine adopts a fork current and a static plate heat exchanger.That is, the movement direction of hot and cold gases is perpendicular to each other,The air

I want to make a device to filter well water with quartz sand, but I don't know how to do it, and the flow of well water is also very large, and I don't know how much to do. Diameter 1.5 m plate thickness 4mm garden head two high 2.5 M garden can open 108 on the middle hole side and leave the feeding tank.Automatic welding inner coating professional paint 3mm with vertical 5.5kw water pump flow 80 square pressure into the upper hole of the garden tank.The lower hole is connected to the variable frequency constant pressure water supply.Quartz is placed in quartz sand at both ends about 1 cm (don't be too thin and too thin ).Water into the tank.Design pipe-oriented backwashing.The above is a tank for water washing and bath in a hot well on site for reference.Two kinds of water inlet and rotary sand remover (cone type) on the submersible pump to the drinking water core filter.With gauze,Use a big jar to drain so much trouble. just buy one. it's not much more expensive to do than buy and the effect of trouble is
