Description
Technical Field
A disinfectant powder atomizing device cleaning agent, application and a cleaning method thereof belong to the technical field of atomizing device cleaning.
Background
Potassium hydrogen persulfate is an effective disinfectant, is a white powdery solid capable of flowing freely at normal temperature, and is easily soluble in water. The acidity of the aqueous solution is caused by the generation of hydrogen ions due to the dissolution of potassium hydrogen sulfate in the complex salt. However, potassium hydrogen persulfate has much better stability under acidic conditions than neutral conditions, and rapidly decomposes under alkaline conditions. Its mechanism of killing microorganisms can be explained as: 1. under the condition of aqueous solution, potassium hydrogen persulfate releases nascent oxygen to directly carry out oxidation reaction on microbial cell wall protein. 2. Free hydroxyl groups are released, interfering with the microbial enzyme system, quickly leading to inactivation of the microbial protein molecules. Research shows that when potassium persulfate acts on small molecular organic matters, such as relatively long-chain aldehyde and amine organic matters, free hydroxyl is used for promoting the reaction. Toxic and harmful 'three-cause' byproducts are not generated, and only K + and SO4 are slightly increased (for example, the K + increment is 0.03ppm and the SO4 increment is 0.06ppm when the K + and the SO4 are added into the water body according to 0.5 ppm).
At present, potassium hydrogen persulfate is mostly applied to sterilization and disinfection of water, but is also suitable for prevention and disinfection of certain livestock diseases in the breeding industry, such as swine fever, due to the excellent effect of the potassium hydrogen persulfate on virus inactivation.
However, if the potassium hydrogen persulfate is sprayed in an atomizing mode, the potassium hydrogen persulfate is easy to separate out crystals from liquid mist in the atomizing process, particularly, the crystals are easy to separate out near the spraying holes of the atomizing device, so that the spraying holes are blocked, and sometimes, the dissolved disinfection powder is required to be atomized even at high temperature, so that the disinfection powder separated out of the crystals is carbonized and hardened and is insoluble in water, and the blockage is difficult.

The sodium dodecyl sulfate can improve the permeation and solubilization effects of the detergent on disinfectant powder crystals, the glycol and the isopropanol can gradually dissolve crystals from the outside of the disinfectant powder crystals according to the proportion, the detergent has the characteristic of atomization, and the glycol and the isopropanol can volatilize into mist after being heated, so that the size of detergent liquid drops is reduced, and the detergent liquid drops can more easily enter the inside of the disinfectant powder crystals. Water acts as a carrier for the above ingredients.
Preferably, the composition comprises the following components in parts by weight: 30 parts of ethylene glycol, 20 parts of iso-diol, 1 part of sodium dodecyl sulfate and 49 parts of water. The optimal proportion can realize the most efficient and sufficient crystal cleaning of the precipitated disinfection powder.
The application of the disinfectant powder atomizing device cleaning agent is characterized in that: is used for cleaning the hydrogen potassium persulfate disinfection powder atomization device.

Examples 13 to 15 and comparative examples 15 to 16
A method for cleaning a disinfectant powder atomizing device and a cleaning method thereof, wherein the disinfectant powder atomizing device cleaning agent prepared in the embodiment 1 is used for cleaning a potassium hydrogen persulfate disinfectant powder atomizing device. Preparing a solvent from 40kg of propylene glycol, 22kg of ethylene glycol, 0.5kg of sodium dodecyl sulfate and 37.5kg of water, wherein the weight ratio of potassium hydrogen persulfate to the solvent is 1: 25 preparing a disinfectant powder solution, pressurizing the disinfectant powder solution by a pump, conveying the disinfectant powder solution to an electric heating device, heating the disinfectant powder solution to 180 ℃, volatilizing and spraying the disinfectant powder solution, wherein a flowmeter is arranged on the pump, and the flow rate is 5L/h; and conveying the cleaning agent of the disinfection powder atomizing device prepared in the embodiment 1 to an electric heating pipe by a pump to heat to 130-160 ℃ every 10 minutes of the disinfection powder solution atomized by the disinfection powder atomizing device, and spraying the cleaning agent out of a nozzle of the disinfection powder atomizing device, wherein a flow meter is arranged on the pump. Specific heating temperature, flow and cleaning time are shown in the following table 1, wherein whether the blockage is caused is the blockage condition of the spraying opening after the disinfection powder atomization device circularly works for 1 hour.
TABLE 1 cleaning Process parameters
According to Table 1, the dissolution efficiency of the atomized detergent for the crystals of the disinfectant powder is lowered by the heating temperature of the detergent being too low, and a longer cleaning time is required at the same flow rate, so that eventually even if the flow rate is lowered to sufficiently heat the detergent and prolong the cleaning time, the crystal solids are not sufficiently dissolved. And when the temperature is too high, the disinfection powder crystals near the spraying opening are heated and carbonized and crystallized to form more compact solid, so that the cleaning agent is more difficult to enter the interior of the crystallized solid.
Performance testing
The disinfection powder atomization devices in examples 7-12 and comparative examples 8-14 were tested to be operated circularly until the blockage time, and the blockage process of the disinfection powder atomization device is characterized in that the pump pressure of the disinfection powder solution is increased firstly, and then the flow rate is slowly decreased, so the operation time is rounded down for 5 min.
The results of the performance testing are shown in Table 2 below.
Table 2 results of performance testing
According to table 2, when the content of sodium dodecyl sulfate exceeds the range of the present invention, the cleaning ability is greatly reduced because the absorption of water carrier is reduced due to its too high concentration, and the crystal can not be sufficiently dissolved as the glycol and the isopropanol enter the crystal, and the boiling point of the whole system is reduced due to the too high content of the glycol and the isopropanol in the system, the water content of the atomized cleaning agent is reduced at the same temperature, and the permeability to the crystal is reduced. The proportion of the ethylene glycol to the isopropanol ensures the dispersion effect of the atomized cleaning agent, and the finer the dispersion of the liquid drops, the better the cleaning effect.
The foregoing is directed to preferred embodiments of the present invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof, and the scope thereof is determined by the claims that follow. However, any simple modification, equivalent change and modification of the above embodiments according to the technical essence of the present invention are within the protection scope of the technical solution of the present invention.
