Jinan exhaust hood, which is produced by us, adopts the principle of impinging stream. Its core technical equipment is an active high-speed gas-liquid contact device. The equipment has the characteristics of high mass transfer coefficient, small volume, high purification efficiency and low energy consumption, and its oil fume purification efficiency can reach more than 95%. There is no gas-liquid contact mechanism of mechanical power and control device in the reaction box of the system. It is the fume purification device with higher purification efficiency, lowest operation cost and smallest volume in the existing fume purification equipment.
The exhaust hood is composed of a hood and upper and lower parts of the hood. The hood is composed of three planes. The hood consists of four planes (or baffles) which are front, rear, left and right. The lower end of the cone is connected with the hood body, the upper end is connected with the hood hood, and the movable baffle is opened on any side of the hood body or the cover near the window. The front baffle has a beautiful and delicate gap, and the smoke is exhaustive, without polluting the environment, which is beneficial to human health, simple structure and low cost.
The iron exhaust hood is only a rectangular iron hood with a hole connected to the exhaust pipe and covered above the stove table. By using the principle of hot air rising, the lampblack can be pumped out of the room naturally. The smoke exhaust hood has the advantages of simple process and low cost, but its smoke exhaust effect is poor, and it is only suitable for small food places with little smoke. At present, there are no stereotyped products, but according to the size of the kitchen on-site production.
As far as possible, the cross-section shape of the hood is similar to the horizontal projection of the smoke emission source.
The shrinkage angle of the exhaust hood should be equal to or less than 60 degrees, and the maximum should not be greater than 90 degrees. In order to reduce the height of exhaust hood, the long side of rectangular exhaust hood can be segmented.
The vertical edge (skirt edge) of the hood should be kept at a certain height, and the height of the vertical edge should be the hood area.
