1. The principle of selecting oil fume purifier

(1) The technology is reliable, the purification rate is stable and meets the standard requirements. The nominal purification rate in the introduction of technical indicators is the purification rate at the initial stage of use, not a stable index. If it is not maintained in time or used for a long time, the purification rate will drop sharply. The purification rate of some purification technologies drops very quickly. For example, if the filter material is not replaced in time, it will be impossible to exhaust smoke after blockage.

(2) the operation cost is low. It is necessary to calculate the operating expenses such as water and electricity, especially the implied operating expenses. In the technical data consulted, the products do not explain the pressure loss. If the resistance is large, the power consumption needs to be increased, and it needs to be calculated to know.

(3) Good fire resistance. Soot purification has a good fire fighting function, especially for stoves with open flames, which is more necessary.

(4) the occupied space is small. According to the environmental conditions of the kitchen, choose equipment that occupies less space or equipment that can be installed in the air.

(5) Easy installation, cleaning and maintenance.

2. Precautions for installation of oil fume purifier

(1) Select an oil fume purifier that matches the exhaust air volume of the fan. The treatment air volume of oil fume purifier is generally greater than the exhaust air volume of fan. The estimation method based on the stove head is not accurate, because the treatment air volume of the oil fume purifier increases with the use time, and the treatment capacity decreases, so a large margin should be left. For the pipeline system with large smoke exhaust resistance, the power consumption can be reduced by selecting an oil fume purifier with appropriate air volume.

(2) Before installation, it is best to power on the equipment for trial operation for a period of time, check the operation effect, and check whether the machine will break down during transportation or handling before installation.

(3) There are specific technical requirements when the fume purifier is connected to the smoke exhaust system, and the pressure loss in the system should be considered to minimize the resistance.

(4) The purifier should be synchronized with the fan as far as possible and switched on and off at the same time.

(5) The equipment box must be safely grounded and connected with the oil drain pipe.
