Embodiment

[0032] Such as Figure 1-7 As shown, a production process of industrial by-product gypsum includes the following process: including a feeding system, a drying and calcining system, a cooling system, a waste heat recovery system and a storage system. The specific operation is as follows:

[0033] The feeding system is as follows: the raw material is gypsum, an industrial by-product, and the material has a certain humidity and viscosity, and is sent to the next process through the feeding belt 1, and the outlet of the feeding belt 1 is connected with a plugboard air lock valve 2, The plug-in air lock valve 2 has the function of locking the air, reducing the entry of cold air outside the system. Once the air leakage is large, it will affect the drying effect of the material, and the plug-in board air lock valve 2 can effectively realize the drying of the wet and sticky industrial by-product gypsum. Feed without blocking.

[0034] There is a movable feeder 3 behind the plugboard...

Abstract

The invention discloses a production process of industrial by-product gypsum. The production process comprises a feeding system, a drying and calcining system, a cooling system, a waste heat recyclingsystem and a storage system. According to the process, advanced equipment such as an inserting plate type air locking valve, a movable feeder, a novel drying calcining kiln, an air heater and a air-cooled rotary cooler is introduced so that feeding and discharging air locking is tight, the drying calcining heat efficiency is high, waste heat is recycled, energy is saved, and the environment is protected. The system is stable in operation and reliable in product quality.

Description

technical field [0001] The invention specifically relates to a production process of industrial by-product gypsum. Background technique [0002] At present, the resource utilization of industrial by-product gypsum has attracted people's attention. The utilization of industrial by-product gypsum needs to be dried and calcined first to remove the water in it. The current drying and calcination of industrial by-product gypsum generally adopts rotary equipment heated by coal. Such equipment has the problems of high energy consumption and low output. Contents of the invention [0003] Purpose of the invention: In order to solve the deficiencies of the prior art, the present invention provides a production process of industrial by-product gypsum. [0004] Technical solution: A production process of industrial by-product gypsum: including a feeding system, a drying and calcining system, a cooling system, a waste heat recovery system and a storage system; details are as follows:...
