Description
Technical Field
The invention relates to the field of boiler water supply, in particular to aquatic product water softening equipment.
Background
Cigarette factories are typically equipped with low pressure steam boilers, the softened water supplied to which is typically made from a sodium bed. The sodium bed produces demineralized water by adsorbing calcium and magnesium ions from the water onto a resin. When the sodium bed has a large amount of calcium and magnesium ions adsorbed by the resin, the hardness of the produced softened water is high, and the sodium bed needs to be regenerated. The regeneration treatment refers to treating the resin in the sodium bed by using concentrated brine to recover the activity of adsorbing calcium and magnesium ions, backwashing and forward washing the sodium bed, and then washing the resin adsorbed with the concentrated brine to be clean, so that the sodium bed can be started again.
Generally, the regeneration of the sodium bed needs to go through three processes of salt absorption, backwashing and forward washing, wherein the salt absorption process consumes a large amount of strong brine, and the backwashing and forward washing process consumes a large amount of natural water. In the practical application process, after the water yield of the sodium bed reaches a set value, the regeneration treatment is automatically carried out. Even if the final water production is not qualified, the sodium bed will continue to produce water if the set water production is not reached. If the water production is unqualified, the sodium bed is switched after the sodium bed is stopped in a mode of manually and forcibly stopping the water production. In addition, the salt absorption time, the backwashing time and the forward washing time in each sodium bed regeneration treatment are all fixed time. And (4) after the salt absorption reaches the set fixed time, backwashing, and after the backwashing reaches the set fixed time, performing forward washing, wherein after the forward washing reaches the set fixed time, the regeneration of the sodium bed is finished, and the process enters a standby process.
In order to ensure that the produced water is qualified after regeneration, the salt absorption time, the backwashing time and the forward washing time are set to be relatively long and fixed, so that a large amount of water resources are wasted.
Therefore, how to provide a softened water producing device which can accurately control the regeneration treatment time of the sodium bed and save water resources becomes a technical problem which needs to be solved urgently in the field.

As shown in fig. 1, when the first sodium bed 25 starts automatic regeneration and absorbs salt in the first step, the electric valves 64 and 63 are automatically opened, at this time, the electric valves 24, 26, 62 and 61 around the sodium bed are closed, the brine in the brine tank 1 enters the pipeline 18 through the valve 2, the water pump 3, the check valve 4, the valve 5, the pipeline 6, the valve 7, the float flowmeter 8 and the pipeline 10, the softened water passes through the valve 70, the water pump 71, the check valve 72 and the valve 73 from the soft water tank 11, one path of the softened water passes through the valve 76 and the pipeline 77 and is utilized by the boiler 78, and the other path of the softened water also enters the pipeline 18 through the valve 75, the pipeline 74, the pipeline 69, the pipeline 14, the valve 15 and the float flowmeter 16. After the concentrated brine and the softened water are mixed into salt solution with a proper proportion in the pipeline 18 according to a certain proportion, the salt solution enters the first sodium bed 25 from the pipeline 18 through the probe 19, the pipeline 20, the valve 66 and the electric valve 64, the salt solution generates a displacement reaction with resin in the first sodium bed 25, calcium and magnesium ions adsorbed on the resin are melted into the salt solution, and then the salt solution is discharged into a trench through the electric valve 63, the valve 65, the hardness probe 67 and the pipeline 68. The float flowmeter 8 and the float flowmeter 16 are transparent, scales are arranged on the surface of the float flowmeter, the floats 9 and the floats 17 are respectively arranged in the floats, and the scales of the positions of the floats 9 and the floats 17 can be observed by adjusting the opening sizes of the valves 7 and 15, so that the amount of the salt water entering and the amount of the softened water entering can be adjusted, and the concentration of the salt water can be determined. The concentration of the salt solution is determined, after the salt solution enters the first sodium bed 25, calcium and magnesium ions adsorbed by the resin in the first sodium bed 25 enter the salt solution, so that the hardness of the salt solution is increased when the salt solution is discharged through the sodium bed, the calcium and magnesium ions adsorbed by the resin in the sodium bed are gradually reduced along with the salt absorption process of the first sodium bed 25, the hardness of the salt solution discharged through the first sodium bed is gradually reduced, finally, the calcium and magnesium ions adsorbed by the resin in the sodium bed are completely replaced, and the hardness of the discharged salt solution is close to the hardness of the imported salt solution. So when hardness probe 67 detects that the hardness of the discharged brine is close to or equal to the hardness detected by hardness probe 19 at the inlet, it indicates that the calcium and magnesium ions adsorbed by the first sodium bed resin have been completely displaced into the brine discharge and the resin has recovered activity. At this point, the electro valve 64 closes and the first sodium bed 25 stops absorbing salt. That is, when the hardness probe 67 detects a hardness close to or equal to the hardness detected by the hardness probe 19 at the inlet, the salt absorption is stopped, and at the same time, the electric valve 26 is opened to automatically enter the backwashing process.
During backwashing of the first sodium bed 25, tap water continuously enters the first sodium bed through the pipeline 40, the pipeline 38, the pipeline 28, the valve 27 and the electric valve 26, salt liquid and impurities remained in the first sodium bed 25 are backwashed (in a reverse flow direction to the produced water), and the backwash water is discharged into a trench through the electric valve 63, the valve 65, the hardness probe 67 and the pipeline 68. Since the resin in the first sodium bed 25 has completely recovered its activity, calcium and magnesium ions of the backwash tap water can be adsorbed. After a period of backwashing, the salt solution remained in the first sodium bed 25 is washed clean, and at the moment, the hardness of the discharged backwashing water gradually approaches zero. When the hardness of the discharged backwash water is 0, this indicates that the backwash is sufficient, and the backwash is stopped, that is, when the hardness probe 67 detects that the hardness of the discharged water is zero, the electric valve 26 and the electric valve 63 are closed to stop the backwash. At the same time, the electric valves 61 and 62 are opened, and the first sodium bed 25 automatically enters the forward washing program.
During the normal washing of the first sodium bed 25, tap water continuously enters the first sodium bed through the pipeline 40, the pipeline 39, the pipeline 42, the pipeline 55, the pipeline 56, the valve 59 and the electric valve 61, a small amount of salt solution and impurities remained in the first sodium bed 25 are washed in a forward direction (the same as the flow direction of produced water), and the normal washing water is discharged into a trench through the electric valve 62, the valve 60, the chlorine root probe 58 and the pipeline 57. Since the first sodium bed 25 is backwashed, although a large amount of residual salt solution and impurities are washed away, the effluent hardness is zero. However, the sodium bed is not easy to be thoroughly washed because the resin with the grain size of millet is arranged in the sodium bed, so that the sodium bed is washed again by forward washing. As the tap water does not generate chlorine radicals when passing through the sodium bed, and the resin does not filter or adsorb the chlorine radicals, the chlorine radicals in the sodium bed are remained in the saline water and carried by the tap water, and the content of the chlorine radicals in the discharged water is higher than that of the tap water when the forward washing is started. As the resin is washed clean, the chlorine radical in the discharged water is basically equivalent to the chlorine radical in the inlet tap water, namely when the resin in the first sodium bed 25 is completely washed clean, the chlorine radical content in the discharged water is the same as that in the tap water, at the moment, the chlorine radical probe 58 detects that the chlorine radical content (a value can be set according to the local tap water chlorine radical content) is close to that of the tap water, the electric valve 61 and the electric valve 62 are closed, and the forward washing is immediately stopped. At this point, it is indicated that the resin in the first sodium bed 25 is thoroughly cleaned and the first sodium bed 25 is ready for production of water.
When the first sodium bed 25 produces water, tap water continuously enters the first sodium bed 25 through the pipeline 40, the pipeline 39, the pipeline 42, the pipeline 55, the pipeline 56, the valve 59 and the electric valve 61, calcium and magnesium ions in the tap water are adsorbed by resin in the first sodium bed to form softened water, the softened water enters the soft water tank 11 through the electric valve 24, the valve 23, the hardness probe 21, the pipeline 22, the pipeline 13 and the valve 12, one path of the softened water in the soft water tank 11 can be used by the boiler 78 through the valve 76 and the pipeline 77 after passing through the valve 70, the water pump 71, the check valve 72 and the valve 73, and the other path of the softened water is used for sodium bed regeneration after being matched with saline water after passing through the valve 75, the pipeline 74, the pipeline 69, the pipeline 14, the valve 15 and the float flowmeter 16. During the water production process of the first sodium bed 25, the resin in the sodium bed starts to have high activity and can completely adsorb calcium and magnesium ions in water, so that the hardness of the produced softened water is zero. However, with the increase of the water yield of the first sodium bed, the adsorption of calcium and magnesium ions by the resin in the sodium bed is increased, the activity is gradually reduced, and the produced softened water gradually has hardness, but the hardness value of the softened water is still in the standard range of the boiler water. And with the further increase of the water yield of the first sodium bed 25, the hardness of the produced softened water gradually increases and reaches the upper limit value of the boiler water standard, namely at the moment, the hardness probe 21 detects that the hardness of the softened water produced by the first sodium bed 25 reaches the upper limit value (which can be set according to the softened water hardness standard), the first sodium bed 25 stops producing water, the system automatically switches to the second sodium bed to start producing water, and the first sodium bed 25 enters a regeneration program.
When the disodium bed 34 regenerates and absorbs salt, the electric valve 50 and the electric valve 49 are automatically opened, at this time, the electric valve 33, the electric valve 35, the electric valve 48 and the electric valve 47 around the disodium bed 34 are in a closed state, the strong brine in the brine tank 1 enters the pipeline 18 through the valve 2, the water pump 3, the check valve 4, the valve 5, the pipeline 6, the valve 7, the float flow meter 8 and the pipeline 10, and the softened water also enters the pipeline 18 through the valve 75, the pipeline 74, the pipeline 69, the pipeline 14 and the float flow meter 16 after passing through the valve 70, the water pump 71, the check valve 72 and the valve 73 from the soft water tank 11. After the concentrated brine and the softened water are mixed into salt solution with a proper proportion in the pipeline 18 according to a certain proportion, the salt solution enters the second sodium bed 34 from the pipeline 18 through the probe 19, the pipeline 30, the valve 52 and the electric valve 50, the salt solution generates a displacement reaction with resin in the second sodium bed 34, calcium and magnesium ions adsorbed on the resin are dissolved into the salt solution and then are discharged into a trench through the electric valve 49, the valve 51, the hardness probe 53 and the pipeline 54. When the hardness probe 53 detects that the hardness of the discharged brine is close to or equal to the hardness value detected by the hardness probe 19 at the inlet, the electric valve 50 is closed, the salt absorption of the second sodium bed 34 is stopped, and simultaneously, the electric valve 35 is opened to automatically enter a backwashing program. When the disodium bed 34 is backwashed, tap water continuously enters the disodium bed 34 through the pipeline 40, the pipeline 38, the pipeline 37, the valve 36 and the electric valve 35, the salt solution and impurities remained in the disodium bed 34 are backwashed (in the reverse direction of the flow direction of produced water), backwash water is discharged into a trench through the electric valve 49, the valve 52, the hardness probe 53 and the pipeline 54, and when the hardness probe 53 detects that the hardness of discharged water is zero, the electric valve 35 and the electric valve 49 are closed, and backwashing is stopped. At the same time, the electro valves 47 and 48 are opened and the disodium bed 34 automatically enters the forward washing program. During the second sodium bed positive washing, tap water continuously enters the second sodium bed 34 through the pipeline 40, the pipeline 39, the pipeline 41, the valve 45 and the electric valve 47, a small amount of salt liquid and impurities remained in the second sodium bed 34 are positively washed (the flow direction of produced water is the same as that of the produced water), and the positive washing water is discharged into a trench through the electric valve 48, the valve 46, the chlorine root probe 44 and the pipeline 43. When the chlorine content detected by the chlorine probe 44 (the value can be set according to the local tap water chlorine content) is close to the tap water chlorine content, the electric valves 47 and 48 are closed, and the forward washing is immediately stopped. At this point, the resin in the second bed is thoroughly cleaned and the second bed is ready for production of water. When the disodium bed 34 produces water, tap water continuously enters the disodium bed 34 through the pipeline 40, the pipeline 39, the pipeline 41, the valve 45 and the electric valve 47, calcium and magnesium ions in the tap water are adsorbed by resin in the disodium bed 34 to become softened water, and the softened water enters the soft water tank 11 through the electric valve 33, the valve 32, the hardness probe 31, the pipeline 29, the pipeline 13 and the valve 12. When the hardness probe 31 detects that the hardness of the softened water produced by the second sodium bed 34 reaches an upper limit value (which can be set according to the hardness standard of the softened water), the second sodium bed 34 stops producing water, the system automatically switches to the first sodium bed 25 to start producing water, and the second sodium bed 34 enters a regeneration process.
Because the chlorine content in tap water is very low, and the sodium bed does not generate chlorine and absorb chlorine, if the chlorine in softened water is higher, the sodium bed is not washed clean, because the main source of the chlorine is the chlorine in the brine. And the high chlorine radical has great influence on the water quality of the boiler, and particularly, the high chlorine radical can cause the high electrical conductivity of the boiler water and the increased pollution discharge. Therefore, according to the change rule of chlorine radical during the regeneration and water production of the sodium bed, the forward washing time of the sodium bed is controlled by detecting the chlorine radical content through the chlorine radical probe.

It will be appreciated by those skilled in the art that modifications may be made to the above embodiments without departing from the scope and spirit of the invention.
