Background technique

Lime has a long history as an agent for surface water clarification and softening. With the popularity of lime supply and the continuous improvement of quality, lime powder has gradually expanded to become a supplement for urban reclaimed water reuse treatment, tap water pH adjustment, flue gas desulfurization treatment, sludge drying and disinfection in sewage treatment plants, and circulating cooling water system. Leading treatment chemicals for water or side stream water treatment.

In environmental technology, lime has been considered as the lowest cost alkaline raw material, neutralizer and water softener. Its well-known high pH value characteristics can also be used to precipitate heavy metals, and transform waste heavy metal sewage and heavy metal sludge into valuable and reusable raw materials. For this reason, lime powder, as a green environmental protection agent, will have an important role in the future. wider application prospects.

In the water treatment process, lime is generally made into a suspension or slurry before being added to the system. In large-scale water treatment projects, lime silos are usually used to store lime powder, and then the dry powder feeder is used to continuously transport the lime powder to the lime mixing tank to make lime milk. The common lime milk configuration device, such as the application number 201120328266.0 The Chinese patent usually includes a container, the container has inlets for water and lime, and an agitator is arranged in it, and the lime solution configured in the container is pumped to the application place such as a clarifier through a slurry delivery pump, but this The configuration device of milk of lime has the following problems:

1. The traditional configuration device has only one mixing container, and the lime solution can only be stirred in the mixing container. The flow stroke is short and the fluidity is poor. There are some larger particles and impurities in the lime solution and due to reasons such as insufficient lime dissolution, there are often more large particles in the lime solution, which leads to uneven concentration of the solution and reduces the quality of the solution. During subsequent use, these large particles enter After the pipeline, it is easy to cause problems such as pipeline blockage and pump wear; moreover, when the stirring is stopped, these particles will settle at the bottom of the mixing container, and cannot be effectively discharged from the mixing container, and are easy to deposit, which will not only block the low-level conveying pipe The liquid inlet of the road, and the space of the mixing container is reduced.

2. Because lime milk has a certain degree of adhesion, it will adhere to the inner wall of the container or pipe. With long-term use, the lime milk will continue to deposit, which will easily cause blockage of the container and pipe, affecting normal use, and depositing The lime milk layer is difficult to remove, which is not conducive to the subsequent configuration of lime solution.

Therefore, lime and tap water can be fully contacted in real time to reduce the problem of local agglomeration. As the liquid level of the solution in the primary dissolving chamber 111 gradually increases, the mixed solution passes through the overflow channel 12 from the primary dissolving chamber 111 Enter the inside of the secondary drug-dissolving chamber 112, and further mature and dissolve under the agitation of the agitator, and then enter the bottom of the final-stage drug-dissolving chamber 113 from the overflow passage on the upper part of the secondary drug-dissolving chamber 112, and be stirred by the agitator Better dissolution, mixing and homogenization under

In each drug-dissolving chamber, large particles settle under the action of gravity and gather to the bottom of each drug-dissolving chamber along the inclined plate.

Moreover, in the process of acid supply, the supply of tap water can also be carried out at the same time, so as to facilitate the acid solution to enter each drug-dissolving chamber, and stop water supply and acid supply when the liquid level in the last-stage drug-dissolving chamber reaches a high liquid level Of course, when the acid solution in the final drug dissolving chamber reaches the medium level, the pneumatic pump can also be started to introduce the acid solution in the final drug dissolving chamber into the liquid supply pipeline 20 .

S40, then, open the second solenoid valve SV02, the third solenoid valve SV03 and the fourth solenoid valve SV04, close the other solenoid valves, feed air into each drug-dissolving chamber, and perform aeration for a period of time. Next, the lime scale layer attached to the wall surface of each drug-dissolving chamber 11 is further driven to peel off and fall off.

S50, subsequently, open the seventh solenoid valve SV07, the eighth solenoid valve SV08, the ninth solenoid valve SV09, the tenth solenoid valve SV10 and the fifth solenoid valve SV05, close other solenoid valves, and discharge the waste water in each dissolving chamber and pipeline After the discharge, the seventh solenoid valve SV07 , the eighth solenoid valve SV08 , the ninth solenoid valve SV09 and the tenth solenoid valve SV10 are closed.

S60, open the fifth solenoid valve SV05 of the liquid supply pipeline 20 and the first solenoid valve SV01 of the water supply pipeline, close other solenoid valves, add tap water to the dissolving chamber, when the water level in the final dissolving chamber 113 reaches the middle When the liquid level is reached, the pneumatic pump PU01 is turned on, and each drug dissolving chamber and the liquid supply pipeline 20 are washed with tap water for a period of time, and part of the cleaned sewage is discharged from the second liquid discharge branch 203 .

After cleaning, the whole device enters the standby state, and waits for the sewage treatment station to issue an operation command, the device enters the operation state, and starts to prepare the solution and supply the liquid according to the set program.

Of course, in the whole descaling process, the cleaning cycle and the time of each step can be adjusted according to the actual situation, and the order of descaling can also be other orders, for example, pickling and aeration can be carried out directly, or not.
