Automatic flocculant solution preparing and quantitative adding system for sugar refinery and operating method thereof

Abstract

The invention provides an automatic flocculant solution preparing and quantitative adding system for a sugar refinery and an operating method thereof. A storage tank of the system is connected to a flocculant proportioning tank with a stirrer and a liquid level gauge by means of a quantitative feeding device and a water pipe equipped with a proportioning water valve. The flocculant proportioning tank is connected with a temporary flocculant storage tank with a flocculant flow meter and a flocculant flow adjustment valve, and then connected to a temporary sugar juice storage box, and a sugar juice flow meter is installed on a sugar juice delivery and output pipe of the temporary sugar juice storage tank. A main flocculant control unit adds flocculant powder as required by preparation into the proportioning tank, and then adds water to mix. The mixture is pumped into the temporary flocculant storage tank. The main flocculant control unit monitors sugar juice flow in real time and acquires and controls flocculant solution flow entering the temporary sugar juice tank. The automatic flocculant solution preparing and quantitative adding system automatically controls the concentration of the prepared flocculant solution accurately, and the precise flocculant amount is added accurately into the unit volume of the sugar juice to achieve the best flocculating effect and the operation is simple.

Description

technical field [0001] The invention relates to the technical field of automatic control of sugar factory production, in particular to a sugar factory flocculant solution automatic preparation and quantitative addition system and operation method. Background technique [0002] Flocculants refer to agents that can destabilize solutes, colloids, or suspended particles in aqueous solutions to produce flocs or flocculent precipitates. [0003] Sugar flocculant is a kind of flocculation material specially used to treat sugar materials and make them produce flocculation effect. At present, the sugar industry at home and abroad mostly uses sugar flocculants to improve the efficiency of sugar juice treatment, which is economical and convenient. A small amount of flocculant for sugar can be used in the clarification section of the sugar factory to achieve good flocculation effect, accelerated particle settling speed, increased filtration speed, shortened processing time, increased s...

AI Technical Summary

Problems solved by technology

However, in the production process of the sugar factory, the flow rate of the sugar juice often appears high and low, and the speed of the metering pump cannot be adjusted from time to time.

[0007] Therefore, in the current sugar factory production process, it is impossible to add an appropriate amount of flocculant according to the real-time status of the sugar juice, and it is difficult to achieve the desired effect of the flocculant.
