Aluminum system flocculating agent preparing apparatus

Abstract

The invention provides a set of aluminum-type flocculant production device, which belongs to a polymerization chemical reaction device. The production device is characterized in that a reaction kettle lined with corundum bricks and a regulation kettle lined with corundum bricks are major equipment. The reaction kettle changes the heating type into the direct heating type in the cavity of the kettle. A horizontal type spiral centrifugal solid-liquid separator, a flue gas and steam boiler system, an acid steam recovery system and an operational control cabinet are corollary equipment. The reaction kettle, the regulation kettle and the operational control cabinet are mounted on an indoor operating floor. The solid-liquid separator, the steam boiler system, an acid storage tank, a settlement maturation pond and a drug storage pond are all positioned outdoors. The devices are connected with one another by pipe-lines. Various pumps are arranged in the pipe-lines for feeding and discharging materials. The device has advantages of greatly improved wear resistance of internal walls of the reaction kettle and the regulation kettle, extended service life by eight times, fast heating of materials, high dissolution rate, high thermal efficiency and non acid contamination. The gas boiler system has advantages of less occupied area, low running cost of manual work, safety and reliability, and non smoke contamination and cinder. The device is energy-saving and environment-friendly, and has outstanding economic benefit and social benefit.

Description

(1) Technical field [0001] The present invention relates to the production equipment of flocculant, in particular to the production equipment of aluminum series flocculant. (2) Background technology [0002] Polyaluminum chloride (PAC) and polyaluminum ferric chloride (PAFC) are the mainstream products of aluminum-based flocculants, and their production processes include "one-step method" and "two-step method". When the "one-step" production process is adopted, the main production equipment is a cement pool lined with an anti-corrosion layer. The advantage is less equipment investment and low labor cost; the disadvantage is that the dissolution rate of active ingredients is low, the reaction time is too long (about 3 days), the acid mist pollution is serious, and the production facilities occupy a large area. When the "two-step method" production process is adopted, the main production equipment is a glass-lined reaction tank and a regulating tank, and its supporting equipm...
