Embodiment 1

[0054] Embodiment 1 A kind of phosphorus-free corrosion and scale inhibitor

[0055] The invention discloses a non-phosphorus corrosion and scale inhibitor, which is prepared from water, zinc salt, polymaleic anhydride, L ascorbic acid and polyaspartic acid, calculated by weight and number: 12 parts of zinc salt, poly 28 parts of maleic anhydride, 8 parts of L-ascorbic acid, 32 parts of polyaspartic acid, and the balance of water constitute a hundred parts by weight.

[0056] The phosphorus-free corrosion and scale inhibitor of the present invention has the following advantages:

[0057] 1. Control corrosion and deposition, be stable to halogen, adopt alkaline treatment scheme, reduce the amount of acid or not add acid, and reduce the cost of enterprise chemicals;

[0058] 2. Phosphorus-free chemicals not only reduce bacterial growth and phosphate precipitation pollution, but also meet environmental protection emission requirements;

[0059] 3. The corrosion and scale inhibi...

Embodiment 2

[0132] Embodiment 2 A kind of preparation device of phosphorus-free corrosion and scale inhibitor

[0133] The invention also discloses a preparation device for the above-mentioned non-phosphorus corrosion and scale inhibitor, such as Figure 1-12 As shown, it includes a reaction kettle 1, a stirring mechanism, a back-mixing mechanism 6, a connector 4, a circulation pump 7, a feeding piping system and an air distribution piping system 16. Wherein, the stirring mechanism is installed on the reaction kettle 1 , and the stirring mechanism includes a stirring shaft 3 extending into the reaction kettle 1 for stirring the mixture liquid in the reaction kettle 1 . The back-mixing mechanism 6 is detachably mounted on one end of the stirring shaft 3 extending into the reactor 1, and is used for spraying the mixture liquid into the reactor 1 in an umbrella shape. Circulation pump 7 is installed on the outer wall of reaction kettle 1, and the outlet end of this circulation pump 7 is com...

Embodiment 3

[0143] Embodiment 3 A kind of preparation method of phosphorus-free corrosion and scale inhibitor

[0144] The invention also discloses a preparation method of a phosphorus-free corrosion and scale inhibitor, such as Figure 14 As shown, it specifically includes the following steps:

[0145] S1. Control the outlet solenoid valve on the outlet pipe of the circulating pump, the liquid inlet solenoid valve on the connecting pipe and the water solenoid valve on the clean water branch pipe connected to the water storage container in the liquid inlet branch pipe to open through PLC, and then PLC controls the circulation pump Turn on, so that the circulating pump injects the clear water in the water storage container into the reaction kettle through the back-mixing mechanism;

[0146]S2. When the clean water injection volume reaches the preset value, the electromagnetic flowmeter transmits the signal to the PLC, and the PLC receives the signal and controls the solenoid valve of the ...

Abstract

The invention discloses a phosphorus-free corrosion and scale inhibitor, which is prepared from clear water, zinc salt, polymaleic anhydride, L ascorbic acid and polyaspartic acid, and has good biodegradability and double corrosion and scale inhibition. Functional water treatment agent, this new type of agent is suitable for high-alkali and high-solid water systems, has good compatibility with commonly used bactericidal algicides, strong chemical stability, is not easy to decompose and reduce efficiency, and has no environmental pollution when discharged; and provides this kind of non-toxic The preparation method and equipment of the phosphorus corrosion and scale inhibitor solve the problems of insufficient stirring and long stirring time of the existing stirring mechanism. The invention is applicable to the technical field of water treatment chemicals and preparation equipment thereof.

Description

technical field [0001] The invention belongs to the technical field of water treatment chemicals and preparation equipment thereof, and in particular relates to a phosphorus-free corrosion and scale inhibitor, a preparation method and a preparation device. Background technique [0002] With people's increasing awareness of environmental protection and stricter environmental laws and regulations, people put forward higher and higher requirements for scale inhibitors. However, the existing scale inhibitors have weak degradability, and their components contain phosphorus, nitrogen, etc., and their biodegradability is poor, so they are not suitable for high-alkali and high-solid water systems. Relatively weak, easy to decompose and reduce efficiency, discharge will cause pollution to the environment. In the preparation process, the mixing of the material and liquid is mostly made by stirring the reaction kettle through the stirring mechanism. The current stirring mechanism is a...
