1、 Factors to consider when designing a desulfurization, denitrification, and dust collector: 1. Temperature and composition of flue gas: desulfurization, denitrification, and dust collector; The usage temperature is an important basis for design, and the selection of filter material is often based on the flue gas temperature. For example, suitable cooling methods and layout methods need to be considered for high-temperature flue gas to determine the appropriate selection. In addition, the presence or absence of corrosive gases in the flue gas determines the selection of filter materials and dust collector casing materials. Therefore, the composition of the flue gas is also a factor considered in the design of desulfurization, denitrification, and dust collectors. 2. Processing air volume: The processing air volume determines the size of the desulfurization, denitrification, and dust collector. Generally, the processing air volume is based on the operating air volume. Once the processing air volume is determined, the filtering area can be determined based on the determined filtering air speed. 3. Inlet dust concentration and outlet dust concentration: Inlet dust concentration is also an important factor in the design of desulfurization, denitrification, and dust removal equipment. It involves design elements such as equipment resistance, dust cleaning device design, filter material and box wear, as well as the selection of filtration wind speed and whether to add pre dust removal devices. The design of these elements is directly related to the standard emission of dust concentration at the outlet, so it should be considered thoroughly. In addition, factors such as properties, equipment resistance, equipment pressure resistance, dust cleaning pressure and methods, and airflow velocity are all considered in the design of dust collectors, and are equally important. 2、 The standard for selecting a desulfurization, denitrification, and dust collector is to determine whether a type of desulfurization, denitrification, and dust collector is required based on whether it is a flammable and explosive working environment and the working level. 2. Starting from the frequency of use and working time of desulfurization, denitrification, and dust collectors, choose whether they can be used continuously for 24 hours. Generally, desulfurization, denitrification, and dust collectors are selected to work continuously for 24 hours. 3. Determine the environmental cleanliness level based on the operating conditions and whether to use a cleanroom dust collector. 4. Considering the specific gravity and quantity of dust, this is a prerequisite for determining the power and capacity of vacuum cleaning equipment. Generally speaking, the power and capacity of the selected equipment should be slightly higher than the actual demand; In addition, the humidity of the dust is a condition that determines whether to choose a dry or wet vacuum cleaner. If it is a dry vacuum cleaner, it cannot be used to suck liquids or dust with high humidity. 3、 Technical characteristics of desulfurization, denitrification and dust collector: 1. Multiple alkaline desulfurizers can be used, and local materials can be obtained. 2. High workload, operation. 3. The power consumption is low and will not increase the power of the fan, because its swirl device has a guiding effect and can reduce resistance. 4. Equipped with a dehydration and defogging device, the fan can dehydrate without water or dust. 5. The desulfurization and dust removal methods can achieve high desulfurization efficiency and meet dust removal standards. 6. The large water supply pipe will not cause blockage problems. 7. The desulfurizer can be used with ammonia alkali solution or lime water, which can be reused multiple times and prevent secondary pollution. 8. The use of materials in the equipment can not only improve the service life of the water film dust collector, but also enable continuous operation. 9. Superior atomization performance can improve the desulfurization effect. 4、 The inspection before the operation of the desulfurization, denitrification and dust collector is to check whether the desulfurization, denitrification and dust collector device is stable. This may seem insignificant, but the normal operation of the desulfurization, denitrification, and dust collector is very important. The equipment that needs to be used for a long time must be sturdy. 2. Prevent the presence of flammable and explosive materials in the surrounding area. 3. Is there any noise during the operation of the desulfurization, denitrification, and dust removal equipment. If the function of the desulfurization, denitrification and dust collector is stable, there will be no noise during operation. If there is noise, it should be stopped immediately to check whether the equipment is installed correctly. 4. We need to test the fan to see if it can work properly. The fan inside the equipment plays a crucial role in the normal operation of the desulfurization, denitrification, and dust collector. The function of the fan determines the effectiveness of the equipment's desulfurization. It is important to maintain the fan regularly. 5、 The principle of designing desulfurization, denitrification, and dust collectors is to minimize the investment and operating costs of the desulfurization and denitrification system, and to achieve significant social and economic benefits through optimized processes after the completion of the desulfurization and denitrification system. 2. Fully combining the objective conditions and requirements of users, adapting measures to local conditions, making full use of existing resources and limited space, optimizing and combining, and formulating targeted and practical technical solutions. 3. While emphasizing equipment performance, try to reduce the operating costs of the system as much as possible and pay attention to the rational selection of equipment. 4. The selected desulfurization and denitrification processes not only improve the efficiency of desulfurization and denitrification, but also ensure the economic operation of the system.
