Description

Technical Field

[0001] The invention belongs to the technical field of water treatment, and relates to a resin scrubbing water level self-adaptive regulating control device and method. Background Art

[0002] Ion exchange resins are widely used in water purification systems because of their renewable and recyclable characteristics. Before the resin is regenerated, it needs to be scrubbed to remove suspended impurities adsorbed by the resin during operation, so that the exchange reaction between the functional groups on the resin and the impurity ions in the water can proceed smoothly.

[0003] The water level is the main control factor for operators when performing resin scrubbing operations. If the water level is too low, a scrubbing dead zone is likely to occur inside the regeneration tank, resulting in poor regeneration of resin that has not been fully scrubbed; if the water level is too high, the resin is likely to leak from the exhaust valve at the top of the regeneration tank with the water flow, resulting in a shortened operating cycle of the resin. Therefore, relevant standards stipulate that the scrubbing water level should be about 200mm higher than the top surface of the resin layer. According to the survey, there are currently two main ways to control the resin scrubbing water level. One is manual visual control through the central peephole of the regeneration tank, and the other is to first fill the regeneration tank with water and then use program-controlled logic to fix the drainage time control. However, in actual operation, the former method not only has a delayed response, but is also prone to problems of uncontrollable or inaccurate control. For example, when the amount of resin is too much or too little, the middle sight glass cannot see the resin interface at all, or the resin surface is uneven, resulting in the inability to accurately control the water level. In addition, manual visual control also has the risk of working at heights. The latter method not only wastes a large amount of desalted water, but also has poor adaptability. When the amount of resin changes, it is easy for the scrubbing water level to be too low or too high. Summary of the invention

[0004] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art and provide a resin scrubbing water level adaptive adjustment control device and method, which can automatically and accurately control the resin scrubbing water level.

[0005] To achieve the above object, the present invention discloses a resin scrubbing water level adaptive regulation control device, comprising a first distance measuring sensor, a second distance measuring sensor, a water inlet pipe, a drainage pipe and a resin regeneration tank;

[0006] The first distance measuring sensor is installed at the middle position of the middle row pipe in the resin regeneration tank, the second distance measuring sensor is installed on the inner side of the top of the resin regeneration tank, the water inlet pipe is connected to the inlet of the middle row pipe in the resin regeneration tank, and the drainage pipe is connected to the drainage port at the bottom of the resin regeneration tank;

[0007] A water inlet flow regulating module is provided on the water inlet pipeline;

[0008] A drainage flow regulating module is arranged on the drainage pipeline.

[0009] Furthermore, it also includes an adaptive regulation controller, which is connected to the first distance measuring sensor, the second distance measuring sensor, the water inlet flow regulation module and the water outlet flow regulation module.

[0010] Furthermore, the adaptive regulation controller is connected to the first distance measuring sensor, the second distance measuring sensor, the water inlet flow regulation module and the water outlet flow regulation module by means of wireless communication or wired communication.

[0011] The further improvement of the resin scrubbing water level adaptive regulation control device of the present invention is:

[0012] The invention discloses a resin scrubbing water level adaptive regulation control method, comprising the following steps:

[0013] 1) After the resin is input, the adaptive adjustment controller obtains the initial measurement value of the first distance measuring sensor. When the initial measurement value of the first distance measuring sensor is greater than 0, it goes to step 2); when the measurement value is equal to 0, it goes to step 6);

[0014] 2) The adaptive regulation controller starts the water inlet flow regulation module and the drainage flow regulation module, and simultaneously obtains the measurement value of the first distance measuring sensor;

[0015] 3) When the measurement value of the first distance measuring sensor gradually becomes stable and remains unchanged from the fluctuating state, the adaptive regulation controller controls the drainage flow regulation module to be closed, and controls the water inlet flow regulation module to maintain the low flow mode operation. At the same time, the measurement value h1 of the first distance measuring sensor is obtained. When h1≥Wmm, go to step 4); when h1<Wmm, go to step 5);

[0016] 4) The adaptive adjustment controller obtains the measurement value of the first distance measuring sensor. When the measurement value of the first distance measuring sensor is equal to h2, the adaptive adjustment controller controls the water inlet flow adjustment module to close, and the resin scrubbing water level adaptive adjustment control process ends;

[0017] 5) The adaptive adjustment controller obtains the measurement value of the second distance measuring sensor. When the measurement value of the second distance measuring sensor is equal to h3, the adaptive adjustment controller controls the water inlet flow adjustment module to close, and the resin scrubbing water level adaptive adjustment control process ends;

[0018] 6) The adaptive regulation controller turns on the water inlet flow regulation module and the drainage flow regulation module, so that both the water inlet flow regulation module and the drainage flow regulation module maintain high flow mode operation, and obtains the measurement value of the second ranging sensor at the same time. When the measurement value of the second ranging sensor gradually stabilizes from a fluctuating state and remains unchanged, the adaptive regulation controller obtains the measurement value h4 of the second ranging sensor, turns off the drainage flow regulation module, controls the water inlet flow regulation module to maintain low flow mode operation, and obtains the measurement value of the second ranging sensor. When the measurement value of the second ranging sensor is equal to h5, the adaptive regulation controller controls the water inlet flow regulation module to turn off, and the resin scrubbing water level adaptive regulation control process ends.

[0019] The further improvement of the resin scrubbing water level adaptive regulation control method of the present invention is:

[0020] Furthermore, h2=h1-200mm.

[0021] Furthermore, h3=preset value+h1-200mm.

[0022] Furthermore, the preset value is the distance from the center position of the middle row to the center position of the top of the resin regeneration tank.

[0023] Furthermore, h5=h4-200mm.

[0024] Further, W=200.

[0025] Furthermore, the adaptive regulation controller is connected to the first distance measuring sensor, the second distance measuring sensor, the water inlet flow regulation module and the water outlet flow regulation module by wireless communication or wired communication.

[0026] The present invention has the following beneficial effects:
