Description

Technical Field

[0001] This utility model relates to the field of gas transportation technology, and in particular to a pipeline filter structure for a flammable gas safety conveyor. Background Technology

[0002] A flammable gas safety conveyor is a complex system composed of multiple devices, including a conveying pipeline, pressure regulator, safety valve, flow meter, leak detection sensor, automatic shut-off valve, fire and explosion protection devices, and a monitoring system. These devices work together to ensure the safety and stability of flammable gas during delivery. Among these, the filter, as a key component, is used to remove impurities (such as particulate matter, moisture, and oil) from the gas in the conveying pipeline to ensure gas purity. However, existing filters, while designed to maintain a certain gas flow rate in the initial stage of the pipeline, often exhibit significant gas resistance. Furthermore, as the amount of adsorbed impurities increases, the filter is prone to clogging, and the resistance gradually increases. This not only affects the gas flow rate but also adversely impacts pipeline pressure regulation. Utility Model Content

[0003] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0004] To address the aforementioned problems, this utility model provides the following technical solution: A pipeline filtration structure for a flammable gas safety conveyor includes a filter disposed within a conveying pipe, characterized in that: the filter comprises a main guide plate, an absorbent paper sheet, and a cap; the main guide plate is provided with a plurality of guide fluids, which are staggered on the main guide plate, and each guide fluid has a guide head, the guide heads being oriented approximately the same; the absorbent paper sheet covers the guide fluids and the main guide plate; and the cap is movably disposed on the main guide plate covered with the absorbent paper sheet.

[0005] As a preferred embodiment of the pipeline filtration structure of the flammable gas safety conveyor of this utility model, the structure of the fluid guide includes, but is not limited to, herringbone and V-shaped structures.

[0006] In a preferred embodiment of the pipeline filtration structure of the flammable gas safety conveyor of this utility model, the guide fluid includes a top end, a bottom end, and a side end. The top end forms a guide head, and the side ends extend from the top end to the bottom end, with the spacing between the side ends gradually increasing from the top end to the bottom end.

[0007] In a preferred embodiment of the pipeline filter structure of the flammable gas safety conveyor of this utility model, the side end is bent inward.

[0008] In a preferred embodiment of the pipeline filter structure of the flammable gas safety conveyor of this utility model, the periphery of the main guide plate is provided with a sealing edge, and the sealing edge is sealed to the inner surface of the cover.

[0009] In a preferred embodiment of the pipeline filtration structure of the flammable gas safety conveyor of this utility model, the guide fluid is placed between the guide main plate and the cover, and is in sealed contact with both the guide main plate and the cover. When the cover and the guide main plate are closed, the guide fluid, the sealing edge and the cover together form a flow channel.

[0010] As a preferred embodiment of the pipeline filter structure of the flammable gas safety conveyor of this utility model, the filter is arranged in a stacked or ring array manner. By the stacked or ring array arrangement, the cross-sectional area of ​​the air inlet is expanded and its shape is adjusted to adapt to the installation structure of the pipeline.

[0011] As a preferred embodiment of the pipeline filter structure of the flammable gas safety conveyor of this utility model, the filter can be arranged in the pipeline in two opposite installation directions.

[0012] The beneficial effects of this utility model are as follows: the main guide plate achieves smooth airflow and efficient filtration through the synergistic effect of the base plate, guide body, and sealing edge.

By adjusting the length of the base plate and the distribution density of the guide body, the airflow resistance and filtration effect can be optimized to ensure smooth airflow and excellent filtration performance.

[0013] The absorbent paper is removable and replaceable, and the filter is reusable. Attached Figure Description

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0027] Example

[0028] Reference Figures 1 to 7This embodiment of the present invention provides a pipeline filtration structure for a flammable gas safety conveyor, including a filter 100 disposed in a conveying pipe. The filter 100 is characterized in that: the filter 100 includes a flow guiding main plate 101, an absorbent paper sheet 102, and a cover 103. The flow guiding main plate 101 is provided with a plurality of flow guiding fluids 101b, which are staggered on the flow guiding main plate 101, and each flow guiding fluid 101b has a flow guiding head with the flow guiding heads facing approximately the same direction. The absorbent paper sheet 102 covers the flow guiding fluids 101b and the flow guiding main plate 101, and the cover 103 is movably disposed on the flow guiding main plate 101 covered with the absorbent paper sheet 102.

[0029] In the filter 100 of this embodiment, the main guide plate 101 and the cover 103 are connected by a sealing to form a closed structure. The guide fluid 101b and the gap between them together constitute an airflow channel. The main function of the guide fluid 101b is to guide the airflow, while the adsorption paper 102 covering it is used to adsorb impurities in the gas, such as particulate matter, moisture and oil. The material of the adsorption paper 102 can be selected according to the requirements, and its shape matches the guide fluid 101b. For example, it can be installed in a movable manner by opening an adapter slot 102a. The adsorption paper 102, the cover 103 and the main guide plate 101 adopt a movable installation design, which facilitates the regular replacement and maintenance of the adsorption paper 102.

[0030] The main guide plate 101 consists of a base plate 101a, a guide body 101b, and a sealing edge 101c. The sealing edge 101c not only supports the connection between the cover 103 and the base plate 101a, but also ensures the stability of the overall structure. The guide body 101b adopts a herringbone or V-shaped design. When gas enters from its tip, the staggered structure aligns the airflow direction with the tip of the guide body, thereby reducing resistance and making the airflow smoother. At the same time, the small-scale vortex formed on the guide body 101b separates large particles and dust through centrifugal force and concentrates them in the smooth section 101e of the guide body, where they are then adsorbed by the adsorption paper 102. Other tiny impurities are further adsorbed through the smooth section 101e and the surface of the adsorption paper 102.

[0031] In practical applications, the length of the base plate 101a and the distribution density of the guide fluid 101b are key factors affecting airflow resistance and filtration effect. By optimization, a suitable base plate length and guide fluid distribution density can be selected, thereby achieving the dual goals of smooth airflow and efficient filtration. This design not only improves filtration efficiency but also reduces maintenance costs and is suitable for various gas filtration scenarios.

[0032] It is worth mentioning that this filter 100 is particularly suitable for the initial location of flammable gas safety delivery pipelines. Its design first ensures smooth airflow, while at the end of the pipeline or in areas where airflow velocity needs to be reduced, multiple filters 100 can be arranged in a stacked or ring array manner, and then... Figure 6 As shown, when the airflow direction is completely opposite, the herringbone or V-shaped opening of the guide fluid 101b faces the airflow direction, forming a certain obstruction, reducing the gas flow rate while generating a larger vortex. This design further enhances the filtration effect while reducing the gas flow rate, realizing two uses for a single filter 100. At the end of the pipe, it ensures both the reduction of airflow rate and the improvement of filtration performance.

[0033] For example, the structure of the guide fluid 101b includes, but is not limited to, herringbone, V-shape or other similar structures that can achieve the function of guiding the flow. Whether the guide fluid 101b is herringbone or V-shape, its function is twofold: first, when the airflow collides with the tip of the guide fluid 101b, it is conducive to the rapid passage of the airflow, thereby reducing the impact on the airflow velocity; second, the opening end of the guide fluid 101b collides with the airflow, which can reduce the airflow velocity and achieve a better filtration effect on gas impurities.

[0034] Specifically, the flow guide 101b includes a top end 101b-1, a bottom end 101b-2, and a side end 101b-3. The top end 101b-1 forms the flow guide head, and the side ends 101b-3 extend from the top end 101b-1 to the bottom end 101b-2, and the spacing between the side ends 101b-3 gradually increases from the top end 101b-1 to the bottom end 101b-2.

[0035] It is worth mentioning that the side end 101b-3 is bent inward. When the gas flows in through the tip of the guide fluid 101b, the curved side end 101b-3 can form a stronger vortex, which improves the effect of the structure in filtering large mass impurities of the gas onto the adsorption paper 102 in the gentle section 101e of the guide fluid 101b by centrifugal force.
