Production method of concrete water reducer
The invention relates to a production method of a concrete water reducer. The method uses powder drying equipment, and the powder drying equipment comprises a tank body, an air supply pipe, a feedingdevice and a collecting device. The production method of the concrete water reducer, adopting the powder drying equipment, comprises the following steps: waste liquid recovery, neutralization treatment, biological fermentation, evaporation concentration and spray drying. High-temperature gas is uninterruptedly conveyed into the tank body through the gas conveying pipe so as to dry the alcohol waste liquid sprayed out of the feeding device, the dried powdery water reducer falls into the collecting device, and the feeding device can change the spraying position of the alcohol waste liquid in thedrying process, so that the spraying range of the alcohol waste liquid is enlarged, and the high-temperature gas utilization efficiency is increased. In addition, the collecting device can vibrate upand down in the working process without additionally arranging a power source, so the situation that gas is discharged due to accumulation of water reducer powder is avoided.
本发明涉及一种混凝土减水剂生产方法，其使用了一种粉末干燥设备，该粉末干燥设备包括罐体、送气管、送料装置与收集装置，采用上述粉末干燥设备生产混凝土减水剂时的具体方法如下：废液回收、中和处理、生物发酵、蒸发浓缩与喷雾干燥。本发明通过送气管不间断地向罐体内输送高温气体，以对从送料装置中喷射出的酒精废液进行干燥，干燥后制得的粉末状减水剂落在收集装置内，在干燥过程中送料装置能够改变酒精废液的喷射位置，使得酒精废液的喷射范围扩大，提高了高温气体的利用效率，此外收集装置无需另设动力源即可在工作过程中上下震动，避免减水剂粉末堆积而对气体的排出造成阻碍。
