Wet material rapid crushing and drying integrated method and system

Abstract

The invention discloses a wet material rapid crushing and drying integrated method and system. The wet material rapid crushing and drying integrated method comprises the following steps that (1) heattransfer crushing for materials is performed, specifically, working hot air is introduced in the process of crushing wet materials into material particles, a strong turbulent flow is formed by the material particles and the working hot air, and preliminary dried material particles are obtained; (2) air flow drying for the materials is performed, specifically, further heat-exchange treatment of thematerial particles obtained in step (1) and the working hot air is performed to obtain dried particles; (3) cyclone material receiving is performed, specifically, the dried particles obtained in step2) and the working hot air are subjected to gas-solid separation treatment to separate the dried particles and tail gas; and (4) dust removal and excess material collection are performed. By integrating the crushing and drying process, the wet material rapid crushing and drying integrated method and system can not only enable the crushing progress smoothly, but also enable the drying efficiency to be improved rapidly; and the hot air is introduced into a crusher to enable the crusher to be a part of a dryer and achieve continuous crushing of the wet materials.

Description

technical field [0001] The invention relates to wet material drying technology, in particular to an integrated method and system for quickly pulverizing and drying wet materials. Background technique [0002] When it is necessary to process wet materials into dry powder materials, due to the high moisture content of wet materials, direct crushing is generally not possible. If it is crushed directly, the moisture contained in the material will be released during the crushing process, and will combine with the crushed fine powder to form a paste, which will adhere to the crushing cutter and grading parts of the crushing equipment, making the crushing work impossible. Therefore, the general conventional treatment method is to slice and cut the wet materials first, then dry these block or sheet materials, and then break them after the materials are dried. Due to the difficulty in drying blocky or flaky wet materials, long drying time, high drying energy consumption, and the nee...

Problems solved by technology

[0004] However, as the society's demand for landscaping gradually deepens and the scale gradually expands, landscaping waste also brings many problems: first, the amount of production increases sharply and accumulates, and the nature of the process of classification, placement, transportation, and consumption It has changed from single to complicated, and the workload has changed from a small amount to a huge amount; secondly, the cost of land has risen, and landscaping wastes have put great pressure on land use due to their huge volume; thirdly, a large amount of organic resources have been wasted extremely Does not meet the transformation demands of today's society for conservation, low-carbon, and recycling utilization

[0007] Therefore, how to quickly, effectively and economically process landscaping waste into wood powder perplexes relevant practitioners, and also limits the processing of increasing landscaping waste
