1、 Characteristics of desulfurization, denitrification and dust collector: 1. Desulfurization, denitrification and dust collector; Suitable for smoke and dust removal as well as desulfurization in steam or hot water boilers, with effects that meet atmospheric emission standards. 2. The desulfurization, denitrification and dust collector has a small volume and light weight. Easy installation and relocation, facilitating multi-level dust removal. 3. The structure of the desulfurization, denitrification and dust collector is tight, with good sealing performance and performance, and low cost and long service life. 4. Strong adaptability to the total amount of flue gas and the concentration and fluctuation of SO2 in flue gas, suitable for coal sulfur content of 0.9-8%. 5. The use of spray water film technology has improved spray efficiency and saved circulating water usage. 6. This product is a wet desulfurization system, where water and gas are fully exchanged. Small dust particles are adsorbed by water mist, and the discharged water is used in a closed cycle through sedimentation. On the one hand, it saves water resources, and on the other hand, it prevents water from flowing into the sewer, causing secondary pollution. Adding lime water solution to water to achieve a pH value greater than 6 can achieve satisfactory desulfurization and denitrification effects. 7. The dust removal performance of the dust collector solves the problem of reduced dust removal efficiency caused by the reduction of boiler load in various dust collectors using the cyclone principle. 8. Lime desulfurization has abundant sources. If digestive ash (powder) is used, it can be directly added to the sedimentation tank. Recycling water containing lime solution is cost-effective. 2、 The operation process of desulfurization, denitrification and dust collector: 1. Before the operation of the desulfurization, denitrification and dust collector, carefully check whether the pH value in the circulation pool is greater than 8, which can achieve the best efficiency. When the pH value is lower than 8, an amount of alkali needs to be added to the circulation pool. 2. When the desulfurization and denitration dust remover starts the circulating system, check whether the bottom valve of the water pump leaks. It is strictly prohibited to operate the water pump without water. After the water pump operates normally, the regulating valve reaches a good state. 3. During the operation of the boiler for desulfurization, denitrification, and dust removal, it is necessary to check whether the circulating acid resistant pump is normal, in order to prevent the dust collector from running out of water, the smoke temperature inside the cylinder, and the possibility of thermal expansion and contraction after entering cold water, which can cause cracks and leakage in the adhesive joints. 4. Activate the fan. 5. The production equipment can only be started after the desulfurization, denitrification, and dust collector has been running for 5 minutes. During each maintenance, the ash residue in the water chamber can be removed to extend the lifespan of the desulfurization, denitrification, and dust collector. 3、 The installation of desulfurization, denitrification, and dust collectors usually requires multiple uses of other dust removal equipment to clean the dust more thoroughly. However, desulfurization, denitrification, and dust collectors only need to be cleaned once, so we do not need to clean them frequently, which saves labor costs. Of course, the frequency of equipment use is not high, which is also conducive to improving its service life. However, regular maintenance is also very important. It adopts the operation method of changing bags, and the user can easily remove the skeleton inside. Moreover, the airtightness of the sealed box ensures that there will be no dust leakage during use, so the effect is good. Users should regularly disassemble and clean it, because if dust accumulates inside for a long time, it will affect the performance of the equipment and shorten its service life. Most of the desulfurization, denitrification, and dust collectors we use in our daily lives adopt the technique of dividing the room and stopping the air flow. Compared to traditional technologies, this dust removal technology has a significantly higher dust removal capacity. In addition, it has the characteristic of low energy consumption. In the modern society that advocates energy conservation, it can also lead the way among similar equipment based on this. Due to its stable performance, it is widely loved by people, especially in the building materials and chemical industries. The installation and use of desulfurization, denitrification, and dust collectors: 1. The installation of desulfurization, denitrification, and dust collectors is generally operated under negative pressure and should be arranged in front of the induced draft fan. During installation, it should be strictly installed according to the instructions. 2. The direction of the flue should minimize bending and there should be no air leakage at any connection. 3. The valve of the water replenishment pipe should be installed indoors. After closing the valve in winter, there should be no water in the pipe to prevent freezing. Regularly check the tightness of the motor belt and replace it in a timely manner. 4. After installation, the water level in the pool should be determined by running and debugging. The overflow water level should be operated normally, and the pH value of the water in the pool should be maintained at 8-10 for desulfurization. 5. Boiler operation: First, start the scraper ash removal machine, open the water replenishment valve, and then turn on the boiler. The water level in the pool should drop by 4-6 centimeters for normal operation. 6. Boiler shutdown: The scraper ash discharge machine should be shut down for at least 10 minutes. The frequency of manual ash discharge should be determined based on the amount of coal ash powder, and the ash storage in the pool should not exceed 350 millimeters above the bottom of the pool.
