Description

Technical Field

[0001] This utility model belongs to the field of water treatment technology, specifically relating to a large-diameter bed water distribution device. Background Technology

[0002] The water distribution device is a core component of the large-diameter bed. Its main functions include: uniformly distributing water to ensure that condensate flows evenly through the resin bed, avoiding channeling and dead zones to guarantee treatment efficiency and resin utilization; preventing resin penetration by acting as a physical barrier to prevent fine resin particles from entering the downstream thermal system, thus avoiding the risk of deposition and corrosion; supporting the resin bed by withstanding the pressure and water flow impact during operation / backwashing; and withstanding pressure differentials by withstanding the pressure drop generated by the resin bed during normal operation and high flow rates.

[0003] With the implementation of CAP1400 and CAP1700 demonstration projects in my country, the volume of condensate polishing has become even larger. Although DN3800 equipment has been adopted, problems such as low resin delivery rate, short operating cycle, and serious exceedance of effluent quality standards have been encountered in actual operation. The root cause lies in the poor uniformity of water distribution and the susceptibility to deformation of large-diameter water distribution devices. Traditional water distribution devices in large-diameter beds, due to limitations in structural design, struggle to achieve uniform water distribution over a large diameter range. Furthermore, the strength and rigidity of the water distribution device are insufficient, making it prone to deformation under high pressure and water flow impact, thus affecting resin delivery efficiency and effluent quality. Utility Model Content

[0004] The purpose of this utility model is to provide a water distribution device for a large-diameter bed to solve the problems of difficulty in achieving uniform water distribution within a large diameter range, and the insufficient strength and rigidity of the water distribution device, which makes it prone to deformation.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a large-diameter bed water distribution device, comprising an upper tank, an integrated water distribution plate horizontally connected inside the upper tank, a resin conveying support pipe vertically arranged on the upper tank, the bottom end of the resin conveying support pipe vertically passing through the water distribution plate, and the resin conveying support pipe being fixedly connected to the water distribution plate, and a perforated pipe being provided at the bottom end of the resin conveying support pipe.

[0006] Furthermore, a perforated pipe is installed at the bottom end of the resin delivery support pipe via a quick connector.

[0007] Furthermore, the branch pipe of the porous pipe is a regular hexagon with three sets of diagonal connecting lines.

[0008] Furthermore, three resin delivery support pipes are provided, and the three resin delivery support pipes are evenly distributed on the 1 / 2D circle of the water distribution plate.

[0009] Furthermore, the porous tubes on the three resin delivery support tubes are arranged at a 60-degree angle to each other.

[0010] Furthermore, the water distribution plate is equipped with a water cap and a movable maintenance plate. The water cap is fixed to the water distribution plate with a clamp, and the movable maintenance plate is fixed to the water distribution plate with fasteners.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This large-diameter bed water distribution device replaces the traditional spliced ​​plate design with an integrated whole plate design, which improves the structural strength and rigidity of the perforated plate, can evenly distribute stress, reduce deformation and resin leakage, and enhance the resistance to load impact. At the same time, the resin delivery support pipe forms a stable three-point support structure with the water distribution plate, cylinder and end cap, which further improves the structural strength and stability of the water distribution device, enabling it to better withstand resin layer pressure, water flow impact and pressure difference.

[0013] This large-diameter bed water distribution device expands the rinsing coverage area by setting up multiple resin delivery support pipes and cooperating with detachable multi-hole pipes at the end. It solves the problems of small rinsing service area, low resin delivery rate and dead ends of a single resin delivery pipe, improves resin delivery efficiency and reduces resin waste.

[0014] This large-diameter bed water distribution device provides sufficient operating space for equipment manufacturing, inspection and maintenance through the setting of movable maintenance plates, which facilitates the review and replacement of a large number of components, reducing maintenance difficulty. The design of detachable multi-hole water distribution branch pipes facilitates internal structure repair, and maintenance and replacement are convenient and quick, reducing maintenance costs.

[0019] The present invention will be further described below with reference to the embodiments.

[0020] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0021] Please see Figure 1-3 This utility model provides a large-diameter bed water distribution device, including an upper tank 1, with a water distribution plate 2 horizontally connected inside the upper tank 1. The water distribution plate 2 adopts an integral design. A resin conveying support pipe 3 is vertically arranged on the upper tank 1. The bottom end of the resin conveying support pipe 3 vertically passes through the water distribution plate 2, and the resin conveying support pipe 3 is fixedly connected to the water distribution plate 2.

[0022] The bottom end of the resin delivery support pipe 3 is connected to a perforated pipe 32 via a quick connector 31. The branch pipes of the perforated pipe 32 are three sets of diagonal connecting lines in a regular hexagon. There are three resin delivery support pipes 3, which are evenly distributed on the 1 / 2D circle of the water distribution plate 2. The perforated pipes 32 on the three resin delivery support pipes 3 are set at a 60-degree angle to each other. The resin delivery support pipe 3 reinforces the weakest part of the large diameter of the water distribution plate 2, so that the water distribution device is subjected to uniform force and the impact resistance is increased. At the same time, the rinsing service range during resin delivery can cover the entire perforated plate, thereby improving the resin delivery rate.

[0023] The water distribution plate 2 is equipped with a water cap 21 and a movable maintenance plate 22. The water cap 21 is fixed to the water distribution plate 2 by a clamp, and the movable maintenance plate 22 is fixed to the water distribution plate 2 by fasteners.

[0024] The working principle of this utility model is as follows: Condensate enters the device and is evenly distributed by the water caps 21 on the water distribution plate 2, ensuring that the water flows evenly through the resin bed and avoiding channeling and dead zones.

[0025] Resin delivery: During resin delivery, the resin flows into the porous pipe 32 for rinsing through the resin delivery support pipe 3. Due to the structure of the porous pipe 32 and the layout of the three sets of porous pipes 32, the rinsing range can be increased.

[0026] Inspection and maintenance: When inspection and maintenance are required, the movable inspection plate 22 can be removed to re-inspect and replace the internal components of the device; if there is a problem with the perforated tube 32, it can be disassembled through the quick connector 31 for maintenance or replacement.

[0027] The above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description, and these obvious variations or modifications derived from the spirit of this utility model are still within the protection scope of this utility model.
