Description

Technical Field

[0001] The utility model belongs to the technical field of dust and saltpeter integrated equipment, and particularly relates to a filter cartridge transverse module and dust and saltpeter integrated equipment thereof. Background Art

[0002] Integrated dust and saltpeter equipment is an ultra-clean filtration device with a composite filter cartridge at its core. It generally consists of a dust collection chamber, a flower plate, a clean air chamber, a dust cleaning system, an ash hopper, and a filter cartridge. The filter cartridge is primarily made of an inorganic binder and mineral fiber that is cured at low temperatures, providing a certain degree of rigidity and enabling long-term operation under high-temperature conditions. The existing filter cartridge installation method is vertical, with the clean air chamber above the dust collection chamber. The flower plate is positioned horizontally, between the clean air chamber and the dust collection chamber. During installation, the filter cartridge enters the clean air chamber from the top and is vertically placed on the flower plate for compression. The flange end of the filter cartridge is compressed and fixed, while the lower end is free.

[0003] Currently, filter cartridges in integrated dust and saltpeter treatment systems are generally installed vertically, meaning they are suspended. The drawback of this structure is that as the flue gas volume to be treated increases, the filtration area must be increased, necessitating the selection of longer filter cartridges or the addition of new chambers. However, the length of filter cartridges currently in use domestically is limited to 3 meters, and longer filter cartridges present significant bottlenecks in production, transportation, and installation. Therefore, given the limited length of filter cartridges, the only way to process more flue gas is to increase the number of chambers. However, increasing the number of chambers increases the system's footprint, the initial investment, and the system's economic efficiency. For projects with limited land, the design and construction complexity increases exponentially. Utility Model Content

[0004] In order to solve the problems existing in the above-mentioned prior art, the utility model proposes a horizontal filter cartridge module and dust and saltpeter integrated equipment.

[0005] The technical solution of the utility model is as follows:

[0015] Preferably, a plurality of perforated plates are provided inside the ash hopper.

[0016] The utility model has the following beneficial effects:

[0017] 1. The horizontal filter cartridge module changes the placement of the filter cartridges and installs a suspension device, switching from a vertical installation to a horizontal one. This optimizes the filter cartridge compartment and reduces its overall size. The filter cartridge compartment is modularized and pre-assembled in the workshop and shipped to the site for assembly. When larger flue gas volumes need to be processed, simply add filter cartridge modules in the vertical direction to filter a larger volume of flue gas without increasing the floor space, resulting in highly economical system operation.

[0018] 2.

After optimization, the clean air chamber and dust collection chamber can accommodate 20% more filter cartridges in the same volume as the vertical filter cartridge integrated dust and saltpeter equipment.

[0019] 3. The clean air chamber of the horizontal filter cartridge module adopts a side flat door cover. Compared with the integrated top cover and split top cover of the vertical filter cartridge dust and saltpeter integrated equipment, it is not only smaller in size, reducing the equipment investment cost and being more economical, but also more convenient and efficient in maintenance and inspection.

[0020] 4. A unique suspension device is added to protect the filter cartridge and further straighten the filter cartridge, solving the problems of insufficient straightness of the filter cartridge when placed vertically, such as small spacing and easy collision of the filter cartridge. The equipment runs more stably and its service life is extended.

[0021] 5. The modular design further standardizes the equipment, shortens the design and production cycle, improves the equipment production and installation accuracy, speeds up the equipment installation progress, shortens the project duration, and can greatly save project execution costs.

[0030] See also Figure 1-2The utility model provides a filter cartridge transverse module, including a filter cartridge module box 3, the filter cartridge module box 3 including a dust removal chamber 32, a filter cartridge 31, a dust cleaning device 7 and a clean air chamber 33; the filter cartridge 31 is horizontally arranged inside the dust removal chamber 32 via a suspension device 35; the dust cleaning device 7 is provided with a blow pipe 71 and an air bag 72, the blow pipe 71 is fixedly extended into the mouth of the filter cartridge 31 through a flower plate pressure plate assembly 34, and is used to clean the filter cartridge. The flower plate pressure plate assembly 34 separates the dust removal chamber 32 and the clean air chamber 33 in the filter cartridge module box 3. The suspension device 35 is provided with a plurality of holes distributed at equal intervals, and a filter cartridge protective sleeve 36 for protecting the filter cartridge is provided in the holes. The protective sleeve 36 is used to protect the filter cartridge 31 and absorb the thermal expansion of the equipment to prevent the thermal expansion deformation of the equipment from squeezing out the filter cartridge (31).

[0031] The installation method of the filter cartridge is: insert the filter cartridge 31 into the flower plate hole of the flower plate pressure plate assembly 34, and at the same time pass it through the hole in the suspension device 35, and fix it with the pressure plate of the flower plate pressure plate assembly 34. After passing through multiple suspension devices 35, the filter cartridge 31 is straightened.

[0032] A dust removal plate 38 is installed between the upper and lower filter cartridges 31 to prevent dust from the upper filter cartridge 31 from accumulating on the lower filter cartridge 31 after cleaning. It also prevents damage to the lower filter cartridge 31 if the filter cartridge 31 breaks. The filter cartridge module box 3 also has a manhole door 6 located above the dust removal chamber 32.

[0038] As a further solution, a number of orifice plates 201 are provided inside the ash hopper 2 to evenly distribute the airflow entering the ash hopper 2 so that the airflow rises evenly. The size and opening ratio of the orifice plates 201 are adjusted and determined based on CFD simulation of airflow distribution according to different project conditions (flue gas volume, chamber volume, number of filter cartridges, etc.).

[0039] Compared with the vertical dust and saltpeter integrated equipment with filter cartridges, the dust and saltpeter integrated equipment with horizontal filter cartridges occupies a smaller area when processing large flue gas volumes. The equipment is more compact and can process larger flue gas volumes with a smaller area. After optimization, the clean air chamber and dust collection chamber can accommodate 20% more filter cartridges in the same volume as the vertical dust and saltpeter integrated equipment with filter cartridges.
