Description

Technical Field

[0001] This utility model relates to the field of flue gas dust removal technology, and specifically discloses a deep flue gas dust removal device based on environmental protection and environmental technologies. Background Technology

[0002] A large amount of flue gas is generated in industrial production and people's daily lives. Therefore, people need to carry out in-depth treatment of the flue gas that pollutes the environment to prevent it from being emitted into the outside world, causing pollution to the surrounding environment and affecting people's health. In order to avoid the harm of flue gas to the environment or human body, it is necessary to carry out dust removal treatment on the flue gas.

[0003] Existing flue gas dust removal equipment filters dust from flue gas using filtration devices. However, the system must be shut down when cleaning the filtration devices, and it lacks an efficient pretreatment structure. This results in large particles directly impacting subsequent filtration units, significantly increasing the system load. Therefore, a deep flue gas dust removal device based on environmental protection and environmental technologies is needed to solve this problem. Utility Model Content

[0004] This utility model proposes a deep dust removal device for flue gas based on environmental protection and environmental technology. Through the combination of parallel cyclone-deep dust removal units and three-way pipeline system, it realizes the continuous operation of the flue gas treatment system without stopping and the modular and convenient maintenance. At the same time, it adopts a gradient purification process that combines spiral blade pre-dust removal with spray-filter plate deep filtration, which significantly improves dust removal efficiency and extends the service life of the equipment.

[0005] This utility model is implemented as follows: a deep dust removal device for flue gas based on environmental protection and environmental technology, including two cyclone filter units and two deep dust removal units, with a first three-way pipe, a second three-way pipe and a third three-way pipe connecting the two cyclone filter units and the two deep dust removal units. The cyclone filtration unit includes a conical cylinder and a cylindrical body connected to the upper end of the conical cylinder. The upper end of the inner wall of the conical cylinder is provided with helical blades, and the interior of the conical cylinder is provided with a filter cylinder that abuts against the helical blades. The deep dust removal unit includes a filter box, a pump body is installed on the upper surface of the filter box, the outlet of the pump body extends into the interior of the filter box and is connected to a spray pipe, a plurality of evenly distributed nozzles are provided at the lower end of the outer wall of the spray pipe, and a plurality of filter plates are provided on the inner wall of the filter box.

[0006] As a preferred embodiment of the flue gas deep dust removal device based on environmental protection and environmental technology of this utility model, a first flange is fixedly connected to the upper end face of the filter cartridge, and a second flange is fixedly connected to the upper end face of the cylinder body. The first flange and the second flange are detachably connected by bolts.

[0007] As a preferred embodiment of the flue gas deep dust removal device based on environmental protection and environmental technology of this utility model, the filter plate and the filter box are detachably connected by bolts.

[0008] As a preferred embodiment of the flue gas deep dust removal device based on environmental protection and environmental technology of this utility model, the outer wall of the filter plate is fixedly connected with two symmetrically distributed limiting blocks, and the inner wall of the filter box is provided with a limiting groove that is slidably connected to the limiting blocks.

[0009] As a preferred embodiment of the flue gas deep dust removal device based on environmental protection and environmental technology of this utility model, the outer walls of the first three-way pipe, the second three-way pipe and the third three-way pipe are all provided with three-way valves.

[0012] The beneficial effects of this utility model are: 1. By using two sets of cyclone filtration units and deep dust removal units set in parallel, along with a three-way pipeline system and valve control, the system can quickly switch to the standby unit to continue working when a single unit is under maintenance. This completely solves the technical problem that traditional dust removal devices must be shut down for cleaning, and significantly improves the efficiency and continuity of equipment operation.

[0013] 2. The cyclone pretreatment structure, which combines spiral blades and filter cartridges, effectively removes large particles and reduces the load on subsequent deep dust removal units. Combined with spray dust suppression and fine filtration of multi-layer detachable filter plates, a gradient dust removal system is formed, which not only significantly improves dust removal efficiency (especially for fine particles), but also extends the service life of core components such as filter plates through modular and detachable design, reducing maintenance costs.
