Description

Technical Field

[0001] This utility model relates to the field of filtration equipment, and in particular to a dry filter box. Background Technology

[0002] In existing technologies, dry filtration equipment is widely used in industrial waste gas treatment, air purification, and other fields, removing particulate matter, harmful gases, or odors from gases by filling them with adsorbent materials or filter media. However, existing dry filtration equipment still has the following technical problems:

[0003] Uneven airflow distribution in traditional dry filter boxes often employs a single channel or a simple filter media arrangement, causing airflow to short-circuit or stagnate within the equipment, preventing sufficient contact with the filter media and thus affecting filtration efficiency. This uneven airflow distribution also results in low filter media utilization and a shortened lifespan.

[0004] Replacing the filter media is a complex operation.

[0005] Many existing equipment designs are not user-friendly enough. Replacing filter media requires disassembling a large number of parts, which is time-consuming and labor-intensive. This not only increases the difficulty of operation but also leads to excessive downtime, thus affecting normal production.

[0006] In summary, existing dry filtration equipment has certain shortcomings in terms of airflow distribution, filter media replacement, and structural flexibility. Therefore, there is an urgent need for a dry filter box with a reasonable structure, high filtration efficiency, convenient operation, and wide applicability to solve the above-mentioned technical problems, improve filtration effect, and reduce operating costs.

[0008] The technical solution provided by this utility model is as follows: A dry filter box, comprising: a box body, two sets of filter media supports disposed in the box body, and filter media filled in the filter media supports;

[0009] The front and rear sides of the box are respectively equipped with air inlets and air outlets, and the top and bottom of the box are respectively equipped with multiple filling ports and multiple unloading ports.

[0015] In one embodiment, the top of the box is provided with a fence with an opening; a ladder communicating with the opening of the fence is provided on the side wall of the box.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

Detailed Implementation

[0024] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0025] like Figure 1-5 As shown, this utility model is a dry filter box, including a box body 1, two sets of filter media supports 2 disposed inside the box body 1, and filter media 3 filled in the filter media supports 2. The box body 1 is provided with an air inlet 4 on the front side and an air outlet 5 on the rear side; the top and bottom of the box body 1 are respectively provided with multiple filling ports 6 and unloading ports 7 for filling and unloading the filter media 3.

[0026] A first channel 8 is formed between the outer sidewalls of the two sets of filter media supports 2 and the sidewall of the housing 1, and a second channel 9 is formed between the two sets of filter media supports 2. A first baffle 10 and a second baffle 11 are respectively provided on the front and rear sides of the filter media supports 2. The first baffle 10 blocks the front end face of the filter media supports 2 and the first channel 8, so that the airflow from the air inlet 4 can directly enter the second channel 9; the second baffle 11 blocks the rear end face of the filter media supports 2 and the second channel 9, so that the filtered airflow can flow from the first channel 8 to the air outlet 5.

[0027] This utility model adopts a distributed arrangement of two sets of filter media supports 2 and filter media 3. By forming a first channel 8 between the outer side wall of the filter media support 2 and the side wall of the housing 1, and forming a second channel 9 between the two sets of filter media supports 2, the air inlet 4 is connected to the second channel 9 and the air outlet 5 is connected to the first channel 8, thereby optimizing the airflow path and maximizing the filtration efficiency. This achieves the technical effects of high-efficiency filtration and uniform airflow distribution, and solves the technical problems of uneven airflow distribution, low filtration efficiency and high energy consumption in the prior art.

[0028] In this embodiment, the filter media 3 can be selected from a variety of filter materials such as Purafil SP, Purafil Select, Chemisorbant, and Chlorosorb Ultr, and can be flexibly selected according to actual needs to meet the filtration requirements in different environments.

[0029] Each filter media support 2 consists of multiple interconnected square tubes 12, which form multiple filling positions 13 for accommodating filter media 3. The filling positions 13 are separated by wire mesh 14, facilitating the filling of filter media 3 while ensuring unobstructed airflow, reducing airflow resistance and improving filtration efficiency. The top and bottom of each filling position 13 correspond to the filling port 6 and the discharge port 7, respectively, allowing for the filling and replacement of filter media 3 using a top-loading and bottom-discharging method. This design not only improves operational convenience but also significantly reduces labor costs by using ton bags for filling and gravity-based unloading.

[0030] The number of filling positions 13 arranged laterally and longitudinally can be flexibly adjusted according to process requirements. In this embodiment, each set of filter media support 2 has three filling positions 13 arranged laterally and five longitudinally, which not only ensures a large filtration area, but also realizes modular design, which is convenient for maintenance and expansion, while reducing structural complexity.

[0031] To further enhance operational convenience and environmental performance, a hinged filling cover 15 and a discharge cover 16 are installed on the filling port 6 and discharge port 7, respectively, to seal the filling position 13 and effectively prevent dust leakage. This sealing design not only improves the environmental performance of the equipment but also reduces filter media waste and extends the service life of the equipment.

[0032] In addition, the bottom of the housing 1 is equipped with support feet 17, providing excellent vibration resistance, ensuring smoother equipment operation, and facilitating equipment fixation and installation. To enhance the safety and convenience of equipment operation, the top of the housing 1 is equipped with a railing 18, which has an opening for operators to enter and exit; the side wall of the housing 1 is equipped with a ladder 19 that connects to the opening of the railing 18, facilitating operators to perform maintenance, inspection, or replacement of the filter media 3 from a height. This user-friendly design effectively improves operational safety and reduces the labor intensity during maintenance.

[0033] The working principle is as follows: airflow enters the second channel 9 from the air inlet 4, is filtered by the filter media 3 in the two sets of filter media supports 2, and then converges from the first channel 8 to the air outlet 5 for discharge. Through reasonable channel design and structural arrangement, not only is efficient airflow filtration achieved, but airflow resistance is also minimized, while ensuring maximum filtration efficiency. This dry filter box has a compact structure, complete functions, high economic and environmental value, and is suitable for airflow filtration needs in various scenarios.
