Description

Technical Field

[0001] The utility model belongs to the technical field of dust collection equipment, and in particular relates to a negative pressure return suction dust removal device. Background Art

[0002] A dust collector is a device that separates dust from flue gas. The performance of a dust collector is expressed by the amount of gas that can be processed, the resistance loss when the gas passes through the dust collector, and the dust removal efficiency. At the same time, the price, operation and maintenance costs, service life, and difficulty of operation and management are also important factors to consider its performance. Dust collectors are commonly used facilities in boilers and industrial production. The types of dust collectors include cyclone separators. As an important gas-solid separation equipment, it is widely used in important fields such as chemical industry and environmental protection for its compact structure, easy operation, stable performance, low pressure loss, and high separation efficiency.

[0003] The existing cyclone dust removal device discharges the dust after internal filtration in a centralized manner through the setting of the bottom discharge component. However, this method makes it easy for dust or other impurities to adhere to the inner wall. Over time, it blocks the internal space and reduces the efficiency of air filtration. As a result, the user is required to manually clean the internal dust and impurities, which is time-consuming and labor-intensive and increases the user's workload. Therefore, we propose a negative pressure return suction dust removal device with easy-to-use functions, which is urgently needed to be developed. Utility Model Content
