Jinan smoke hood for food hygiene and kitchen staff health, smoke exhaust system is a necessary facility for every kitchen. The common equipment includes luxury hood, oil fume purifier, fan and other equipment. The installation of such equipment should be calculated according to the number and area of gas equipment, which must be more than 20% of the area of gas equipment to ensure the air quality. Health inspection departments also have special spot checks and tests.
When building a house, the kitchen must have the design of the kitchen smoke exhaust system, otherwise it can't smoke normally in the later stage, which will not only lead to the family's smog, but also be harmful to the body. However, many people do not understand the design of kitchen smoke exhaust. As a result, there is no normal design. So, next, let's have a look at the principle of kitchen smoke exhaust system and the key points of design. In addition, the kitchen smoke exhaust pipe should be cleaned in daily use, so as to ensure the normal use.
Smoke hood is an important facility in the kitchen. The common smoke exhaust hood is composed of cover and hood. Nowadays, there are umbrella hood and oil mesh hood in the market. Different types have different advantages.
Whether the smoke hood of hotel kitchen is unobstructed is directly related to whether the kitchen can work normally, and the oil fume purification is only a mandatory function of air purification in the kitchen smoke exhaust system. The reasonable matching of smoke exhaust system and purifier is the key to ensure the purification efficiency of the oil fume purifier, and it is also a problem that the designers of the oil fume purifier are easy to ignore. If the smoke exhaust system is not designed reasonably and causes the whole kitchen to smoke exhaust unobstructed, the lampblack purifier cannot be installed, even if the lampblack purifier is installed, it can not work normally.

Since there is no calculation basis for the matching of oil fume exhaust collection system and purifier in GB 18483-2001, there is no reliable and practical calculation method in the actual design of oil fume exhaust system and purifier. Mastering the characteristics of each part of the smoke exhaust system and its impact on the overall smoke exhaust of the kitchen is the premise of the selection and installation of the lampblack purifier, which is of great significance to ensure the normal operation of the fume purifier.
The structure and material of the wall of the kitchen exhaust hood should have enough strength. For the opening of the outer wall of smoke exhaust pipe and air duct, precast concrete block with hole or embedded steel pipe can be used to reserve hole. Insulation wall (to use hollow brick) and normal wall installation method, if the wall is not strong enough, then use wood or other materials for reinforcement.
The smoke pipe installed in the kitchen exhaust hood directly passes through the external wall to the outdoor, and the components to prevent environmental pollution and wind shelter should be set at the outdoor exhaust outlet. For range hood connected by common vertical flue, the section of its vertical flue should be calculated and determined according to the amount of exhaust it bears.
The installation height of the top suction hood should be at least 65 cm above the gas stove, which is suitable between 65 cm and 75 cm.
