Dosing method and device for slowing down drug failure

Abstract

The invention belongs to the technical field of water treatment dosing, and particularly relates to a dosing method and device for slowing down drug failure. In the prior art, a medicament and a solution are generally diluted into a large tank for use; when part of liquid medicine is used due to the fact that the amount of the solution in the storage tank is large, the pesticide effect in the solution is reduced due to continuous reaction of the solution and the solvent; in order to solve the problems that more liquid medicine needs to be added to achieve a good water treatment effect, waste of the liquid medicine is caused and the cost of the process is increased, the method comprises a medicine dispensing step and a medicine adding step, and the liquid medicine is added into the water treatment tank in an extremely short time after being prepared. Aiming at the method, the invention also provides a dosing device for diluting the mother liquor at the tail end of the pipeline and a dosing device for regularly and quantitatively dissolving the solid medicament powder. According to the technical scheme, it can be guaranteed that the medicament effect is hardly affected by deterioration of the medicament, and therefore the use amount of the medicament can be reduced, and the process cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of water treatment dosing, and in particular relates to a dosing method and device for slowing down drug failure. Background technique [0002] In the water treatment process, it often involves the operation of adding various chemicals to the water. However, before the medicament is added to water, it needs to be formulated into a solution for use. [0003] In the prior art, in order to ensure the continuity of the dosing operation, the high-concentration mother liquor dissolved in a bag of solid powder medicine is stored in a storage tank (pool), or the high-concentration mother liquor is directly purchased from the pharmaceutical manufacturer , Store in the storage tank (pool) first, take out a part of the solution diluted to a suitable concentration (easy to mix and add) on the day of use, and store it in another storage tank (pool) for use on the same day or on duty. When it is necessary to add medicin...

Problems solved by technology

[0005] In view of the fact that in the prior art, due to the long storage time of the prepared medicinal solution or the diluted mother liquor, the efficacy of some of the medicinal solutions used later will decrease when used, and more medicinal solutions need to be added to achieve a good water treatment effect, resulting in the loss of the medicinal solution. Waste, the problem of increasing the cost of the process, the present invention provides a drug dosing method and device specifically related to slowing down drug failure, its purpose is to: adopt continuous metering and dissolution or dilution for powder or finished mother liquor, and cancel the storage process after preparation , to realize on-line preparation or dilution for current use; when the dosing point is far away and the dosing amount is relatively small, the powder should be configured into a high-concentration solution first, and then transported to the vicinity of the dosing point for measurement and dilution to the concentration required by the process. The mother liquor is directly transported to the vicinity of the dosing point for measurement and dilution, and diluted to the concentration required by the process
