Inorganic light aggregate spray cooling system and inorganic light aggregate direct spray cooling method

Abstract

The invention discloses and discloses a spray cooling system for inorganic light aggregates, which belongs to the technical field of production and processing of inorganic light aggregates and aims to solve the problem that in the prior art, when the inorganic light aggregates are produced, the temperature is not completely cooled, and the phenomenon of "scalding" is easily caused. The main point of the technical solution is that it includes gas-solid separation equipment, a spray device for spraying water mist to the inner cavity of the gas-solid separation equipment, and a water tank for storing clean water; a pipeline is connected between the water tank and the spray device. A water pump and a valve for controlling the opening and closing of the pipeline are installed on the pipeline. While the gas-solid separation is carried out in the gas-solid separation equipment, the water mist is sprayed through the spray device, so as to achieve the purpose of completely cooling the inorganic aggregate and reducing the phenomenon of "scalding". The invention also discloses a method for cooling the inorganic light aggregate by using the above cooling system. The cooling method has the advantages of thorough cooling, improving the stability of the production process of the inorganic light aggregate and the product quality of the inorganic light aggregate. .

Description

technical field [0001] The invention belongs to the technical field of expanded inorganic light aggregate processing, and more particularly relates to a spray cooling system for inorganic light aggregates and a direct spray cooling method. Background technique [0002] In the production process of using natural gas vertical extruding furnace to produce inorganic light aggregate, due to the high temperature process of the production process and the physical properties of high thermal insulation and strong abrasiveness of the aggregate itself, there are some very serious problems in the existing production process. Practical problems that are difficult to handle properly. These problems have caused great trouble to the quality control of products and the emission of exhaust gas. [0003] figure 1 Shown is the flow chart of commonly used light aggregate production. In the production of light aggregate, especially in the production process of puffed perlite, the initial tempe...

Problems solved by technology

Although this method is economical and convenient, it brings the following problems: 1. When the conveying air pressure is too high, a good cooling effect can be obtained, but it will cause the skin of the product particles to fall off and the particles to be directly broken, which will affect the product quality; 2. When the air conveying pressure is reduced, the occurrence of particle breakage and peeling can be reduced to some extent. However, since the material particle is a kind of heat insulating material with high self-insulation performance, the length of the air conveying pipeline remains unchanged. Under the circumstances, although the temperature of the air transported into the warehouse does not change much from the air temperature of the high-pressure pneumatic transport, in fact, the interior of these lightweight aggregate particles has not been fully cooled, and there is still a lot of heat stored. Once the material is transported After entering the finished product warehouse, after a certain period of time, the heat stored in the particles will be released. After such finished materials are put into the packaging bag, the phenomenon of scalding the packaging bag will still occur.
