FIG. 1 is a schematic plan view of an internal structure of an exchanger according to a preferred embodiment of the present invention.
Detailed Description
In order to make the technical problems, technical solutions and advantageous effects to be solved by the present invention more clearly apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Example 1
Referring to fig. 1, in the preferred embodiment of the method for increasing the purified water amount in the exchanger of the present invention, a resin 2 for purifying water quality is disposed in the exchanger 1. The exchanger 1 is provided with a water inlet 3 and a water outlet 4 respectively. And a water inlet distributor 5 and a water outlet distributor 6 are respectively arranged at the water inlet 3 and the water outlet 4.
The normal water purifying process of the water quality purifying device comprises the following steps: raw water (water to be purified) enters the exchanger 1 through the water inlet 3 and the water inlet distributor 5, contacts with the resin 2 in the exchanger 1, is purified into soft water through the adsorption and purification effects of the resin 2, and then flows out of the exchanger 1 through the water outlet distributor 6 of the water outlet 4.
Before the estimated or measured water quality of the purified effluent of the exchanger 1 is close to the regeneration stage of the resin, the flushing operation is carried out to ensure that the position of the resin 2 in the exchanger 1 is changed irregularly. The quality of the purified water in the exchanger 1 is monitored, but before the quality of the purified water is detected to be close to the lower limit, the flushing process of the resin is automatically started. In the flushing operation, the used flushing water is raw water which the exchanger 1 needs to purify. After the flushing operation is completed, the exchanger 1 is again returned to normal water production.
The number or frequency of flushes of said exchanger 1 is greater than the number or frequency, respectively, of regenerations of its resin 2 during a cycle of production of water by the exchanger 1. The period or time of flushing of said exchanger 1 is less than the period or time, respectively, of regeneration of its resin 2.
The flushing of the exchanger 1 comprises a forward flushing and a backward flushing of the resin inside the exchanger. The forward flushing refers to that under the premise of increasing the water inflow, flushing water enters the exchanger 1 from the water inlet 3 to flush the resin 2 in the exchanger 1 and then flows out from the water outlet 4. The back flushing means that flushing water enters the exchanger 1 from the water outlet 4 to flush the resin 2 in the exchanger 1 and then flows out from the water inlet 3.
The water production cycle here refers to the conventional water production cycle of water purification, and specifically refers to the entire complete process from the end of the last regeneration operation to the completion of the next regeneration operation. The conventional regeneration process comprises the processes of water injection, salt dissolution, backwashing, salt absorption, normal washing and the like which are sequentially carried out. The multiple flushing referred by the invention means that flushing water flows reversely into the exchanger 1 from the water outlet 4 and then flows out from the water inlet 3, and the flushing water flows reversely flush the resin 2 from bottom to top; the flushing water flow positively flows into the exchanger 1 from the water inlet 3 and then flows out from the water outlet 4, and the flushing water flow positively flushes the resin 2 from top to bottom. The back flush referred to in the present invention corresponds to a backwash in a conventional regeneration process. The existing water quality purification device does not carry out backwashing operation in the stage of estimating or actually measuring the water quality to reach the standard, but carries out backwashing or regeneration operation after estimating or actually measuring the water quality to not reach the standard.
After raw water enters the exchanger 1, the raw water is influenced by factors such as pressure and gravity, the flow rate of water flow near the connection line of the water inlet 3 and the water outlet 4 is large, and the resin 2 in the area is quick to lose efficacy. The water flow far away from the connecting line of the water inlet 3 and the water outlet 4 is small, and the resin 2 in the area is slow to lose efficacy, so that the resin in the area cannot be fully utilized, the utilization rate of the resin is reduced, and the waste on the cost is caused. The resin particles are driven to move irregularly in the exchanger 1 by means of the water flow impulsive force during flushing, and after the flushing is finished, the resin particles are subjected to probabilistic displacement, so that the resin 2 in the low water flow area and the resin 2 in the high water flow area are mixed with each other, and part of the resin 2 in the low water flow area is moved to the high water flow area and is fully utilized in the high water flow area.
According to the invention, after one or more back washing operations are carried out before the effluent quality reaches the standard, the utilization rate of resin particles in the whole exchanger 1 can be converged, so that the resin utilization rate of the whole exchanger 1 is improved, and the service life of the resin 2 is prolonged.
The invention makes the resin utilization rate of the whole exchanger 1 not easy to be influenced by the water flow path in the exchanger 1, and the resin particles in the low water flow rate area can obtain the same resin utilization rate as that in the high water flow rate area.
The existing water quality purification device can not effectively utilize the resin 2 in the low water flow rate area in the exchanger 1, so that the utilization rate of the resin is low, and in addition, the shape of the exchanger 1 is limited, so that the filling amount of the resin is low, and the total water production amount of the purified resin is limited.
The resin 2 in the exchanger 1 is washed repeatedly and intermittently by reversely feeding washing water into the exchanger 1 from the water outlet distributor 6 of the water outlet 4, and then discharging the washing water from the water inlet distributor 5 of the water inlet 3 from bottom to top after washing the resin 2, or by positively feeding washing water into the exchanger 1 from the water inlet distributor 5 of the water inlet 3, and then discharging the washing water from the water outlet distributor 6 of the water outlet 4 from top to bottom after washing the resin 2. The water inlet 3 and the water outlet 4 of the exchanger 1 are respectively positioned on the central axis thereof.
The exchanger 1 has a height to diameter ratio of less than 1.5, or a height to width ratio of less than 1.5. The limit that the height-diameter ratio of the exchanger 1 in the prior art is greater than or equal to 1.5 is broken through, under the condition that the height of the exchanger 1 is limited, the volume of the exchanger 1 is increased by increasing the width or diameter of the exchanger 1 under the condition that the height of the exchanger 1 is kept unchanged, the filling amount of the resin 2 is increased, the total water production amount of purified resin is increased, and the application range of the invention is expanded.
The following table shows the purified water volume comparison data of the exchanger under three experimental conditions for water production.
Example 2
As another embodiment of the present invention, a stirring device (not shown in the figure) for stirring the resin in the exchanger 1 is provided on the exchanger 1, and the stirring operation is performed to make the position of the resin 2 in the exchanger 1 change randomly before the quality of the purified effluent water of the exchanger 1 is estimated or measured to be close to the regeneration stage of the resin. After the stirring operation is completed, the exchanger 1 is returned to normal water production. The stirring effect is the same as the flushing effect of the embodiment 1, the positions of the resin 2 in the exchanger 1 are randomly changed, the utilization rate of the resin particles in the whole exchanger 1 can be converged, the resin utilization rate of the whole exchanger 1 is further improved, and the service life of the resin 2 is prolonged.
The number of times or frequency of agitation of the exchanger 1 is greater than the number of times or frequency, respectively, of regeneration of its resin 2, during a cycle of production of water by the exchanger 1. The period or time of agitation of said exchanger 1 is less than the period or time, respectively, of regeneration of its resin 2.
Other structures are the same as the embodiment and are not described again.
The invention also discloses a water quality purification device, wherein an exchanger is arranged in the water quality purification device, and the water quality purification device washes or stirs the resin in the exchanger by using the method for improving the purified water quantity of the exchanger, so as to improve the utilization rate of the resin in the exchanger and prolong the service life of the resin.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
