Coal ash slag comprehensive utilization device and comprehensive utilization method

Abstract

The invention belongs to a coal ash slag comprehensive utilization device and comprehensive utilization method. The device comprises a gasification slag raw material storage bay, a boiler slag raw material storage bay, a gas making slag raw material storage bay and the gasification slag raw material storage bay are connected with the front end of a conveying device through corresponding belt scales, the tail end of the conveying device is connected with an inlet of a ball mill, a gas outlet of the top of the ball mill is communicated with air through a first bag type dust collector and a firstinduced draft fan, an outlet of the ball mill is connected with a tee joint through a first pneumatic conveying chute and a first hoister, a second end of the tee joint is connected with a first finished product warehouse sequentially through a second pneumatic conveying chute, a first tee valve and a second hoister, and a third end of the tee joint is connected with a second finished product warehouse sequentially through a third pneumatic conveying chute, a second tee valve and a third hoister. The device has the advantages that overall investment is low, dust-free production can be realized, operation is simple, and a plurality of varieties of products can be produced according to practical requirements.

Description

technical field

[0001] The invention belongs to the technical field of coal ash and slag reuse, and in particular relates to a coal ash and slag comprehensive utilization device and a comprehensive utilization method. Background technique

[0002] Since 2017, the supply of raw materials for downstream enterprises of coal ash and slag has exceeded demand, and most of the coal ash and slag produced in the production process of the chemical industry have been used by downstream enterprises for free. There are serious environmental protection problems in transportation, which has led to the situation that no one dares to pull chemical companies even if they pay. Coal ash and slag in the chemical industry have become a bottleneck in the development of enterprises. How to solve this problem has become the top priority in the chemical industry event. Contents of the invention

[0003] The purpose of the present invention is to overcome the defects in the prior art and provide a ...
