Industrial production system of active calcium carbonate

Abstract

The present invention discloses an industrial production system of active calcium carbonate. The industrial production system comprises a limestone material bin, a fuel bin, a mixing bin, a calcining tower, an ash forming machine, a carbonization tower, a centrifuge, a rotary drying kiln, a sieving device, a hydrocyclone, an aging pool, an activating machine, a packaging machine and a CO2 collection and purification system, wherein the CO2 collection and purification system comprises a CO2 collection tower, a scrubbing tower, a desulfurization tower and a water-gas separator. According to the present invention, the sieving device, the hydrocyclone and other equipment are introduced into the traditional production system, such that the products at each production link can be timely separated so as to effectively reduce the burden of the subsequent treatment step and ensure the product quality; the aging pool, the activating machine and other equipment are additionally arranged, such that the particle and the activity of the finished product can be effectively ensured and controlled; and the CO2 collection and purification system and the full-automatic packaging machine are introduced, such that the greenhouse gas emission is reduced, the full-automatic operation from the calcination to the packaging is achieved, the labor is effectively saved, the labor cost is reduced, and the significant economic benefits are provided.

Description

technical field [0001] The invention relates to the field of calcium carbonate production systems, in particular to an industrial production system for active calcium carbonate. Background technique [0002] As a high-grade filler with high filling content, active calcium carbonate is widely used in rubber, plastic, plastic-steel doors and windows, PVC cable materials, advanced coatings, pipes, tires, shoe soles, polyethylene blown film, sealing strips, glass steel products, cable packaging cloth , papermaking, building materials, ink, daily chemicals, textiles, feed, food additives and other industries. [0003] At present, the production process of active calcium carbonate in our country mostly adopts a six-step method, namely crushing, calcination, ash, carbonization, dehydration and drying. , and then send the quicklime into the lime machine to get slaked lime, then send the slaked lime to the carbonization tower for carbonization to get calcium carbonate, and then get ...

Problems solved by technology

At present, in the implementation process of this kind of production process, each production step is basically independent, and it is an intermittent production mode. The production processes often need to be connected by human transportation, which wastes labor resources and low production efficiency. At the same time, each processing of the product The lack of reasonable separation equipment between processes often causes troubles to subsequent processes; at the same time, in some processing processes, there is a lack of recovery equipment for production intermediates, resulting in waste of production resources and production costs; 2 The collection, purification and reuse of equipment lead to excessive emissions of greenhouse gases, a greater impact on the environment, and a waste of resources; in addition, in the existing production process, there is a lack of control over the particle size and activity of the product. Controllable adjustment of equipment, resulting in limited application of the product
