Description

Technical Field

[0001] This utility model relates to the field of activated carbon regeneration equipment, specifically a filtration device with a hot circulation pipeline. Background Technology

[0002] Activated carbon is a carbonaceous adsorbent material with a rich porous structure and a large specific surface area. Its main component is carbon, and it also contains small amounts of elements such as oxygen, hydrogen, sulfur, nitrogen, and chlorine. Activated carbon is produced by carbonizing organic raw materials (such as fruit shells, coal, and wood) at high temperatures and reacting them with gases under air-isolated conditions to form a highly porous structure, thereby achieving high adsorption capacity.

[0003] Activated carbon is widely used in water treatment, air purification, food refining, and pharmaceutical decolorization due to its strong adsorption capacity. For example, in water treatment, activated carbon can effectively remove harmful substances and ions from water; in air purification, it can adsorb toxins and odors from the air.

[0004] When the adsorption capacity of activated carbon reaches saturation, it can be regenerated to restore its adsorption capacity and allow for repeated use. Steam regeneration is a commonly used method for regenerating granular activated carbon. This method uses high-temperature steam to treat the activated carbon, desorbing the organic matter adsorbed on it and restoring its adsorption efficiency.

[0005] Activated carbon is regenerated using high-temperature steam. The high-temperature steam enters the regeneration tank, comes into contact with the activated carbon, and then condenses into slightly cooler steam before exiting the tank. This steam is then reheated and reintroduced into the regeneration tank, creating a steam cycle. However, during this cycle, impurities and a small amount of carbon powder from the regeneration tank can be carried into the heat circulation pipes by the steam, eventually entering the steam heating equipment and causing damage.

[0006] To address this issue, the applicant has added a filtration structure to its current activated carbon regeneration production process. Specifically, a filter screen of corresponding mesh size is installed in the thermal circulation pipe between the steam outlet of the activated carbon regeneration tank and the steam heating equipment to prevent carbon powder from entering the steam heating equipment with the steam. However, this filter screen is prone to clogging and can reduce the airflow during equipment operation, thus affecting the thermal circulation efficiency.

[0007] A search revealed no patents related to filtration devices on hot circulation pipelines that could solve the aforementioned problems. Utility Model Content

[0008] To address the aforementioned problems, this utility model proposes a filtration device for a heat circulation pipeline.

[0009] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0010] This utility model provides a filtration device for a hot circulation pipeline, including a cylinder, a screen tube, a baffle plate, and a reducer. The cylinder is provided with a baffle plate, and the baffle plate is provided with a plurality of screen tubes for filtering out impurities and carbon powder entrained in the steam. The inlet end of the cylinder is connected to the steam outlet end of the activated carbon regeneration tank, and the outlet end of the cylinder is connected to the inlet end of the reducer. The outlet end of the reducer is connected to the hot circulation pipeline leading to the steam heating equipment, and the diameter of the outlet end of the reducer is smaller than the diameter of the inlet end.

[0011] Furthermore, a drain outlet is provided at the bottom of the cylinder.

[0012] Furthermore, the inlet end of the cylinder is provided with a first flange for connecting to the steam outlet of the activated carbon regeneration tank.

[0013] Furthermore, the outlet end of the reducer is provided with a second flange for connection to the heat circulation pipeline.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This invention proposes a filtration device for a heat circulation pipeline. By installing a screen tube inside the cylinder, impurities such as carbon powder carried by the steam are filtered. The use of a reducer with a gradually decreasing diameter ensures that airflow is not affected, air volume is not lost, and heat circulation efficiency is not compromised. This achieves the effect of filtering impurities such as carbon powder, avoiding impact on steam heating equipment, and maintaining operating air volume and heat circulation efficiency. Furthermore, a drain port allows for the periodic removal of filtered carbon powder and other debris, as well as water accumulated after steam condensation. This invention has a simple structure, low cost, convenient operation and maintenance, and promising application prospects. Attached Figure Description

[0020] The present invention will now be described in further detail with reference to the accompanying drawings.

[0021] See Figure 1This utility model provides a filtration device for a heat circulation pipeline, including a cylinder 2, screen tubes 3, a baffle plate 4, a reducer 5, a first flange 1, a second flange 6, and a drain port 7. The cylinder 2 is equipped with a baffle plate 4, on which several screen tubes 3 are installed. The baffle plate 4 divides the internal space of the cylinder 2 into two parts, allowing steam entering the cylinder 2 to only pass through the screen tubes 3 before flowing out. The screen tubes 3 can block impurities and carbon powder carried by the steam. A drain port 7 is provided at the bottom of the cylinder 2 for discharging accumulated water and debris. The inlet end of the cylinder 2 is equipped with a first flange 1, which is used to connect to the steam outlet pipe of the activated carbon regeneration tank. The outlet end of the cylinder 2 is connected to the inlet end of the reducer 5. The outlet diameter of the reducer 5 is smaller than the inlet diameter, and the outlet end of the reducer 5 is equipped with a second flange 6, which is used to connect to the heat circulation pipeline.

[0022] Figure 1 The arrow in the diagram points to the right, indicating that the medium flows from left to right. The first flange 1 connects to the pipe at the steam outlet of the activated carbon regeneration tank. Steam from the activated carbon regeneration tank flows into the filter device at point A, passes through several screens 3, enters the reducer 5, and then flows out at point B, entering the heat circulation pipeline. It then enters the steam heating equipment for reheating, and is then fed back into the regeneration tank for activated carbon activation, thus completing the cycle. The screens 3 are fixed to the baffle 4. The airflow passes through the screens 3 for filtration, preventing impurities and carbon powder carried by the steam from flowing into the heat circulation pipeline, thus avoiding any impact on the steam heating equipment. By setting a gradually decreasing diameter reducer 5, the airflow operation is not affected, no air volume loss is caused, and the heat circulation efficiency is not affected. A drain port 7 is provided on the cylinder 2 to periodically drain accumulated water and debris.

[0023] The effect of the filtration device of the heat circulation pipeline of this utility model was experimentally verified, and the results are shown in Table 1.

[0026] The results show that after adding the filter device of this invention to the heat circulation pipeline, the actual measured air volume value fluctuates slightly above and below the theoretical adjustable air volume value, and the upward floating ratio is greater than the downward floating ratio, and the total value also increases. This indicates that the filter device of this invention will not cause loss of operating air volume and will not affect the heat circulation efficiency.

[0027] The above is a further detailed description of the present utility model in conjunction with specific embodiments, and it should not be considered that the specific implementation of the present utility model is limited to this. For those skilled in the art to which the present utility model pertains and related fields, any extensions, operation methods, and data substitutions made based on the technical solution concept of the present utility model should fall within the protection scope of the present utility model.
