Description

TECHNICAL FIELD

[0001] The utility model relates to the filter screen technical field of industrial waste gas desulfurization and denitrification equipment, specifically to filter screen replacement structure of industrial waste gas desulfurization and denitrification equipment. BACKGROUND

[0002] It is known that in the modern industrial production process, the waste gas produced by various industrial activities contains a large amount of harmful substances, such as sulfur oxides (SOx) and nitrogen oxides (NOx), which not only cause serious pollution to the environment, but also have adverse effects on human health. In order to solve this problem, countries have introduced a series of environmental protection regulations, requiring industrial enterprises to carry out desulfurization and denitrification treatment before waste gas emission, in order to reduce the emission of pollutants.

[0003] In the waste gas treatment process, desulfurization and denitrification equipment is one of the key devices that is essential. This kind of equipment usually includes multiple treatment units, among which the filter screen layer is one of the important components, mainly used for intercepting and removing particulate matter and other impurities in the waste gas. With the long-time operation of the equipment, the filter screen layer will gradually accumulate a large amount of pollutants, resulting in a decrease in its filtering efficiency, and even blockage, thereby affecting the treatment effect of the entire system. Therefore, regular replacement of the filter screen layer is an important measure to maintain the normal operation of the equipment and ensure the treatment effect.

[0004] In most cases, replacing the filter screen layer requires disassembling multiple components, which not only consumes a lot of manpower and time, but also may cause the equipment to be out of service for too long, affecting the production efficiency of the enterprise. Since the filter screen layer is located inside the equipment, it needs to ensure the sealing of the equipment during replacement, otherwise untreated waste gas may leak into the environment, causing pollution. However, the traditional replacement method is difficult to achieve this, especially in the case of frequent replacement. Some fixed structures may loosen due to vibration during equipment operation, thereby affecting the position of the filter screen layer and resulting in poor filtering effect, so it is necessary to propose a solution to this technical problem.
