Embodiment 1

[0041] A bag type dust removal device for flue gas treatment, such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 13As shown, it includes a chassis 1, a fixed support 2, a preliminary filter cartridge 3, a blanking frame 4, a preliminary filter assembly 5, a bag-type dust removal assembly 6, and a dust bag scraping assembly 7. The top surface of the chassis 1 is fixedly installed with a fixed support Seat 2, the right side of the middle part of the fixed support 2 is fixed with a preliminary filter cartridge 3, the preliminary filter cartridge 3 is used to separate the particles in the flue gas, the bottom of the fixed support 2 is symmetrically arranged with a blanking frame 4, and the preliminary filter assembly 5 is set On the preliminary filter cartridge 3, the preliminary filter assembly 5 is used for preliminary filtering of the flue gas, and the left side of the fix...

Embodiment 2

[0048] On the basis of Example 1, such as Figure 11 , Figure 12 As shown, a filter heating assembly 8 is also included. The filter heating assembly 8 is positioned in the filter cone 54. The filter heating assembly 8 is used to filter the flue gas and remove moisture. The filter heating assembly 8 includes a fixed ring frame 81 and a curved shaped filter heating tank 82, the filter cone 54 is fixed with a fixed ring frame 81, the bottom surface of the fixed ring frame 81 is provided with a curved filter heating tank 82, the curved filter heating tank 82 will guide and heat the flue gas .

[0049] When the flue gas enters the filtering cone 54, the curved filtering heating tank 82 will guide the flue gas, and the dust in the flue gas will stick to the curved filtering heating tank 82 to achieve the purpose of filtering the flue gas. At the same time, the curved filter heating tank 82 will generate heat and heat the flue gas, so as to avoid excessive moisture in the flue gas...

Embodiment 3

[0051] On the basis of Example 2, such as Figure 11 As shown, it also includes a filter scouring assembly 9, the filter cone 54 is provided with a filter scouring assembly 9, the filter scouring assembly 9 is used to clean the curved filter heating tank 82, and the filter scouring assembly 9 includes Water inlet pipe 91 and annular water outlet pipe 92, filter cone 54 middle part is fixedly connected with water inlet pipe 91, water inlet pipe 91 runs through fixed support 2, and the right end of water inlet pipe 91 is connected with annular water outlet pipe 92, and annular water outlet pipe 92 is used for spraying water The curved filter heating tank 82 is cleaned, and the annular water outlet pipe 92 is located in the filter cone 54 .

[0052] The water inlet pipe 91 is connected with the water delivery pipe. When the curved filter heating tank 82 needs to be cleaned after the dust removal in the later stage, the staff controls the water delivery pipe to pour water towards ...

Abstract

The invention relates to the field of flue gas treatment, in particular to a bag type dust removal device for flue gas treatment. The bag type dust removal device comprises a chassis, a fixed support, a preliminary filter cartridge, blanking frames, a preliminary filter assembly and the like, wherein the fixed support is fixedly mounted on the top surface of the chassis, the preliminary filter cartridge is fixedly mounted on the right side of the middle of the fixed support, the blanking frames are symmetrically arranged below the fixed support, and the preliminary filter assembly is arranged on the preliminary filter cartridge. Under the action of the preliminary filter cartridge, airflow generated by flue gas can do variable circular motion in the preliminary filter cartridge, so the flue gas can generate centrifugal force during rotation to throw solid particles to the inner wall of the preliminary filter cartridge; and the thrown solid particles can slide down along the inner wall of the preliminary filter cartridge, so the effect of separating the flue gas from the solid particles is achieved.

Description

technical field [0001] The invention relates to the field of flue gas treatment, in particular to a bag-type dedusting device for flue gas treatment. Background technique [0002] With the rapid development of industry, various industrial boilers, power station boilers and civil boilers will emit flue gas when burning coal. The flue gas discharged from the chimney of the boiler contains a large amount of dust substances such as stomach smoke and sulfur dioxide. If the dust is inhaled by people Finally, half of it will adhere to the lungs, which will cause various respiratory diseases, and severe cases will cause asthma, pneumoconiosis and lung cancer. Therefore, the high-temperature flue gas generated in the industrial production process needs to be dedusted before it can be discharged into the atmosphere. [0003] To process the flue gas generated in the industrial production process, the flue gas is usually passed into the dust removal equipment to remove dust. The existin...
