Embodiment 1

[0035] AEO the organic material 2 (Fatty alcohol polyoxyethylene ether) and the electrostatic acid and 32% liquid caustic produced during the sulfonation of sulfur trioxide enter the static mixer at the same time. The weight ratio of the electrostatic acid to the liquid caustic is 1:1.5. Fully mix and neutralize in the medium (the temperature after neutralization is 110°C), enter the heat exchanger to exchange heat with dry air, then cool down to 60°C, and then enter the spray dryer. At the same time, the dry air heats up to 90°C through a heat exchanger, then heats up to 140°C through an air heater and enters the spray dryer. After the mixed material is atomized into mist droplets, it is contacted with the hot air in the downstream direction to finally obtain a granular industrial additive with a solid content of 95.3%, an active substance of 21%, a pH of 8.3, and a particle size D85 of 510 μm.

[0036] The granular product can be directly used as a metal cleaning agent, app...

Embodiment 2

[0038] The electrostatic acid and 32% liquid caustic produced during the sulfonation of organic materials α-olefin and sulfur trioxide enter the static mixer at the same time. The weight ratio of the electrostatic acid to the liquid caustic is 1:1.5. Mix and neutralize (the temperature after neutralization is 110°C), enter the heat exchanger to exchange heat with dry air, then cool down to 60°C, and then enter the rotary spray dryer. At the same time, the dry air heats up to 85°C through the heat exchanger, and then heats up to 130°C through an air heater and enters the rotary spray dryer. After the mixed material is atomized into mist droplets, it is contacted with the hot air in the downstream direction to finally obtain a granular industrial additive with a solid content of 94.8%, an active substance of 32%, a pH of 9.3, and a particle size D85 of 545 μm.

[0039]After the granular product is compounded with sodium metasilicate at a mass ratio of 2:1 (stirred and mixed acco...

Embodiment 3

[0041] The electrostatic acid and 40% liquid caustic produced during the sulfonation of fatty acid methyl ester and sulfur trioxide enter the static mixer at the same time. The weight ratio of the electrostatic acid and liquid caustic is 1:1.2, and the two are fully mixed in the static mixer and (the temperature after neutralization is 115°C), enter the heat exchanger to exchange heat with dry air, then cool down to 60°C, and then enter the spray dryer. At the same time, the dry air heats up to 90°C through a heat exchanger, then heats up to 140°C through an air heater and enters the spray dryer. After the mixed material is atomized into mist droplets, it is contacted with the hot air in the downstream direction to finally obtain a granular industrial additive with a solid content of 96.3%, an active substance of 26%, a pH of 6.3, and a particle size D85 of 490 μm.

Abstract

The invention relates to a production process and a production device for preparing industrial additives from electrostatic acid and an application thereof. The provided process and device can be used for preparing the electrostatic acid into the industrial additives, so as to effectively utilize the industrial additives. According to the technical scheme, the production process for preparing industrial additives from electrostatic acid comprises the following steps: 1) respectively conveying the electrostatic acid and liquid caustic into a static mixer and a heat exchanger for mixing and cooling, and drying the mixture in a spray dryer; conveying the mixture into the spray dryer; 2) drying the mixture after atomizing; 3) discharging airflow coming out from the spray dryer by using an induced draft fan; 4) finally, collecting granularity, namely granular industrial additives, from the spray dryer, a cyclone separator and a bag type dust collector. The device for preparing industrial additives from electrostatic acid is characterized by comprising the static mixer, the heat exchanger, an air heater, the spray dryer, the cyclone separator, the bag type dust collector and the induced draft fan.

Description

technical field [0001] The invention relates to a production process, a production device and an application of an industrial auxiliary, in particular to a process, a production device and an application of an industrial auxiliary prepared by atomization drying after neutralization with an electrostatic acid. Background technique [0002] Sulfur trioxide sulfonation is the main process for producing anionic surfactants. After the sulfonation reaction between organic materials and sulfur trioxide, the sulfonated tail gas separated from the gas-liquid separator and cyclone separator contains unconverted sulfur dioxide, unreacted sulfur trioxide, sulfuric acid mist and organic acid mist, directly Emissions can seriously pollute the environment. In order to meet environmental emission requirements, these components must be removed, usually by electrostatic precipitator (ESP) for capture, and then further treated by alkali absorption, etc., and the tail gas is discharged to the ...
