Problems solved by technology

The accuracy of the final concentration after dilution by this dilution method mainly depends on the accuracy of the flow meter and the metering pump. If there is a problem with one of the two during operation, it will lead to inaccurate proportioning concentration.
On the other hand, the dilution system is also often affected by the water supply pressure, resulting in unstable water addition, which eventually leads to unstable concentration of the diluted solution, which will cause the diluted concentration to be compared with the set concentration. The concentration is inaccurate, the waste of mother liquor is serious, and when resetting the dilution concentration, it is necessary to reset the parameters of the flow meter and the metering pump, and the operation is complicated

Embodiment 1

[0023] A method for preparing a peracetic acid solution. When a beverage production line uses peracetic acid solution as a medium for filling equipment and packaging material sterilization, it is necessary to dilute the peracetic acid solution with a concentration of 15% to about 2000mg / kg.

[0024] The equipment used in this embodiment is connected as image 3 As shown, a mother liquor delivery pipe 1 is provided between the mother liquor temporary storage tank and the batch tank, and a valve is provided on the mother liquor delivery pipe 1; the first water inlet pipe 3 is passed between the water tank and the batch tank, and the diameter of the pipe is smaller than that of the first inlet pipe. The second water inlet pipe 2 of water pipe 3 is connected, and the first water inlet pipe 3 and the second water inlet pipe 2 are all provided with valves; the container with the capacity greater than the batch tank is selected as the dilute solution storage tank, and the batch tank a...

Embodiment 2

[0034] A method for diluting a sodium hydroxide solution requires diluting a 40% solution to 1%.

[0035] The equipment connection used in this embodiment is the same as that in Embodiment 1, and will not be repeated here.

[0036] Adopt dilution method of the present invention to dilute this solution, concrete steps are as follows:

[0037] (1) Determination of the capacity of the batch tank;

[0038] (2) According to the concentration requirements of the required configuration, set the liquid level of the concentrated sodium hydroxide solution to the batch tank, and then pump the concentrated sodium hydroxide solution from the mother liquor temporary storage tank into the batch tank until the hydrogen is oxidized Sodium concentrated solution liquid level setting amount;

[0039] (3) Set the water level setting amount for the batch tank, add water from the water tank to the batch tank to the water level setting amount, during the process of adding water, the first water inl...

Abstract

The invention relates to a concentrated solution dilution method. The concentrated solution dilution method includes the steps: (1) measuring volume of a batch tank; (2) setting a concentrated solution level set height for the batch tank according to requirements on the concentration to be prepared, and then pumping a concentrated solution from a concentrated-solution temporary storage tank into the batch tank to the concentrated solution level set height; (3) setting a water level set height for the batch tank, adding water from a water tank into the batch tank to the water level set height, and then uniformly mixing the concentrated solution and the water in the batch tank prior to dilution; (4) enabling a dilute solution diluted in the batch tank to flow into a storage tank for storage and stand-by; (5) repeating the steps (2)-(4) until required production usage amount of the dilute solution is realized. The concentrated solution dilution method is convenient to operate, and the dilute solution obtained by dilution is accurate in concentration.

Description

technical field [0001] The invention belongs to the field of the beverage industry and relates to a dilution method for accurately diluting a high-concentration solution to a required concentration on-line. Background technique [0002] In the prior art, the deployment method of online mixing of water and concentrated solution is generally adopted, such as figure 1 As shown, it is a process flow chart of the dilution method of the concentrated solution in the prior art. A metering pump adds a quantitative concentrated solution to the pipeline, and a flow meter monitors and adds a quantitative amount of water to the same section of the pipeline. Blend with a mixer and add to storage tank. Diluting a concentrated solution in this way presents a number of disadvantages. The accuracy of the final concentration after dilution by this dilution method mainly depends on the accuracy of the flow meter and the metering pump. If there is a problem with one of the two during operation...
