Description

Technical Field

[0001] This utility model relates to the field of steam distribution cylinder technology, specifically a steam distribution cylinder for preventing scaling. Background Technology

[0002] Steam distributors are used to distribute steam generated by heating water in a steam boiler to various pipelines. Existing steam distributors have been found to have several drawbacks during use. Because steam condenses easily when cooled, condensate tends to accumulate at the bottom of the distributor. Furthermore, the steam from the boiler typically contains impurities, much of which accumulate in the distributor as it condenses. Over time, scale and other impurities build up on the inner wall of the distributor, making them difficult to clean, prone to clogging, and corroding the inner wall, thus shortening the distributor's lifespan and affecting its normal operation.

[0003] For example, Chinese invention patent CN219264255U, published on June 27, 2023, discloses a steam boiler steam distribution cylinder, including a main body. The main body is equipped with an inlet pipe, a distribution pipe, and a drain pipe. It also includes a condensate rack, which comprises a condensate plate and a connecting rod. The condensate plate is disposed within the main body and connected to the inner wall of the main body via the connecting rod. The condensate plate is used to collect condensate within the main body. This steam boiler steam distribution cylinder can reduce the amount of condensate accumulating at the bottom of the main body, preventing impurities in the condensate from corroding the inner wall of the main body.

[0004] As can be seen from the above patents, although the steam boiler's steam distribution cylinder is equipped with a condensate plate to collect condensate, it cannot handle the condensate generated when steam encounters the inner wall of the steam distribution cylinder, especially the condensate and impurities at the bottom of the steam distribution cylinder. Condensate and impurities are still likely to remain on the inner wall and bottom of the steam distribution cylinder, which will gradually produce scale. Therefore, the structure of the steam distribution cylinder needs to be redesigned to improve it. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a steam distribution cylinder that prevents scaling.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A scale-resistant steam distribution cylinder includes a cylinder body with a partition in the middle. The upper and lower parts of the partition are respectively an upper cylinder body and a lower cylinder body. The bottom of the lower cylinder body is "V"-shaped, and the bottom of the lower cylinder body makes an angle of 10º with the horizontal direction. The partition extends from the left end to the right end of the cylinder body. The cross-section of the partition is "^"-shaped, and the central axis of the partition is set at an angle of 10º with the horizontal direction. The inner walls of the lower cylinder body and the partition are respectively coated with a water-repellent coating.

[0008] Preferably, a plurality of upper guide plates and lower guide plates are sequentially arranged on the top of the partition and the bottom of the lower cylinder. The edges of the upper guide plates and lower guide plates are tightly attached to the inner wall of the lower cylinder. The upper guide plates and lower guide plates are equally spaced and staggered from left to right. The left and right distances between adjacent upper guide plates and lower guide plates are the same. The number of upper guide plates and lower guide plates is equal. The surfaces of the upper guide plates and lower guide plates are coated with a water-repellent coating.

[0009] Preferably, a filter is provided at the top right end of the partition, the filter faces upward toward the upper cylinder, and a filter medium is provided inside the filter.

[0010] Preferably, a filter plate is provided on the left side of the filter, the filter plate is closely attached to the inner wall of the upper cylinder and the partition, the filter plate is provided with a plurality of air holes, and the filter plate is provided with a filter medium.

[0011] Preferably, an air intake pipe and several air distribution pipes are respectively provided at the top left and middle parts of the upper cylinder body. The air intake pipe passes through the interior of the upper cylinder body and is connected to the partition. The air distribution pipes are located between the air intake pipe and the filter plate.

[0012] Preferably, a drain pipe is provided at the bottom center of the lower cylinder, and a through hole is provided at the junction of the lower guide plate and the bottom of the lower cylinder.

[0013] The beneficial effects of this utility model are:

[0014] The lower cylinder is designed with a "V"-shaped bottom. The inner walls of the lower cylinder and partition, as well as the surfaces of the upper and lower guide plates, are coated with a water-repellent coating. This prevents condensate and impurities from accumulating on the inner walls of the lower cylinder and partition, and from remaining on the surfaces of the upper and lower guide plates. Instead, they flow to the bottom of the lower cylinder, along the inner wall, through the through-hole, and into the drain pipe. This invention solves the problem of condensate and impurities easily remaining on the inner wall and bottom of the air distribution cylinder, leading to the gradual formation of scale. It avoids scale buildup, blockage, difficulty in cleaning, and even corrosion of the inner wall of the air distribution cylinder. Attached Figure Description

[0025] Reference Figure 1 The present invention discloses a steam distribution cylinder for preventing scaling, comprising a cylinder body 1, an upper cylinder body 101, a lower cylinder body 102, a partition 2, an upper guide plate 3, a lower guide plate 4, a filter 5, a filter plate 6, an air inlet pipe 7, a distribution pipe 8, a drain pipe 9, and a through hole 10.

[0026] The partition 2, located in the middle of the cylinder 1, divides the cylinder 1 into an upper cylinder 101 and a lower cylinder 102. The upper cylinder 101 is used to store and release the separated steam, while the lower cylinder 102 is used to separate steam and moisture, which is the coarse separation stage of the steam separator. The "V"-shaped bottom of the lower cylinder 102 has an angle of 10º with the horizontal direction, which facilitates the flow of moisture on the bottom of the lower cylinder 102 along the inner wall of the bottom of the lower cylinder 102 to the tip of the "V"-shaped bottom of the lower cylinder 102. The cross-section of the partition 2 is "^" shaped, and the central axis of the partition 2 is set at an angle of 10º with the horizontal direction, which is also to facilitate the flow of moisture.

[0027] Several upper guide plates 3 and lower guide plates 4 are sequentially arranged on the top of the partition 2 and the bottom of the lower cylinder 102. The function of the upper guide plates 3 and lower guide plates 4 is to guide the high-temperature steam to flow in a curved manner inside the lower cylinder 102, increasing the time and path length of the high-temperature steam flow, making the separation more thorough and sufficient. The edges of the upper guide plates 3 and lower guide plates 4 are tightly attached to the inner wall of the lower cylinder 102. The upper guide plates 3 and lower guide plates 4 are equally spaced and staggered from left to right, and the left and right spacing between adjacent plates is the same. The number of upper guide plates 3 and lower guide plates 4 is equal. The inner walls of the lower cylinder 102 and the partition 2, as well as the surfaces of the upper guide plates 3 and lower guide plates 4, are coated with a water-repellent coating, so that the condensate and impurities in the lower cylinder 102 cannot stay on the inner walls of the lower cylinder 102 and the partition 2, or on the surfaces of the upper guide plates 3 and lower guide plates 4, and will all flow to the bottom of the lower cylinder 102.

[0028] In an optional embodiment, a filter 5 is provided at the top right end of the partition 2, with the filter 5 facing upward toward the upper cylinder 101. The filter 5 is used to further separate the high-temperature steam that has undergone coarse separation flowing from the lower cylinder 102 to the upper cylinder 101. A filter plate 6 is provided on the left side of the filter 5, which is in close contact with the inner wall of the upper cylinder 101 and the partition 2. The filter plate 6 has several air holes distributed on it, and the same filter medium is provided in the filter 5 and the filter plate 6. The filter plate 6 is used to further separate the high-temperature steam that has undergone fine separation by the filter 5, ensuring a thorough and complete fine separation process.

[0029] In an optional embodiment, an air inlet pipe 7 and several air distribution pipes 8 are respectively provided at the top and middle of the left end of the upper cylinder 101. The air inlet pipe 7 passes through the interior of the upper cylinder 101 and is connected to the partition 2, and is used to introduce high-temperature steam generated by the steam boiler heating water into the lower cylinder 102. The air distribution pipes 8 are located between the air inlet pipe 7 and the filter plate 6, and are used to distribute the steam that has undergone coarse and fine separation to various pipelines.

[0030] In an optional embodiment, a drain pipe 9 is provided at the center of the bottom of the lower cylinder 102 for discharging condensate and impurities; a through hole 10 is provided at the junction of the lower guide plate 4 and the bottom of the lower cylinder 102, so that the condensate and impurities flowing to the bottom of the lower cylinder 102 flow through the through hole 10 along the inner wall of the bottom of the lower cylinder 102 and into the drain pipe 9.

[0031] Of course, the embodiments described in this specific implementation are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
