Description
Technical Field
The invention relates to the technical field of humic acid production, in particular to a humic acid spray drying tower built-in screening and discharging system.
Background
Humic acid is a type of organic matter produced and accumulated by the decomposition and transformation of microorganisms and a series of processes of geochemistry, from animal and plant remains (mainly remains of plants). Its total amount is surprisingly large, measured in trillions of tons. Due to its wide existence, it has great influence on the earth, and relates to carbon circulation, mineral migration and accumulation, soil fertility, ecological balance and other aspects. The total amount of humic acid contained in the soil is the largest, but the content of the humic acid is less than one percent on average, and the total amount contained in the brackish water is not small, but the concentration is lower. The most promising humic acid resources are low calorific value coals such as peat, lignite and weathered coal. Among them, the humic acid content is 10-80%. Therefore, in this sense, the production and application of humic acid can also be said to be an aspect of coal chemical industry.
In the humic acid production process, in order to obtain granular humic acid, atomization drying treatment needs to be carried out on liquid humic acid, and only correspondingly, and in the process of atomization drying, particles have sizes due to factors such as an atomization nozzle structure, a feeding rate, a hot air rate and the like. Therefore, in the subsequent processing process, the particles are further dried, and the screening operation is required, so that large particles can be removed, and only correspondingly, most humic acid particles are required to be small, and the particles are large and only occupy a small part, so that the large particles can be better distinguished and removed in the screening process, and if the particles are large, the screening operation cannot be normally performed.
Correspondingly, in the course of working, some customer's demands are different, often have the demand of many sizes granule, if the screening equipment mesh that uses is too single, then can't satisfy diversified size requirement. Except that screening equipment is single, in current workshop, also there is the simplification problem to the processing operation of humic acid, because of present humic acid except single atomizing granulation and drying process, some still need carry out the coating to the granule and handle, this function can't be realized to single equipment from this, and the inside spray drying tower that need dispose two sets of different granulation functions even of enterprise causes actual equipment cost.
