Energy-conserving ventilating method

Abstract

The invention relates to an energy-saving ventilation method, in particular to an energy-saving ventilation method for a basement of a magnetic stirring device. In the method, a wind pumping and conveying line of other wind pumping and conveying equipment and equipment needed to be cooled are connected into a whole; the wind pumping and conveying of other wind pumping and conveying equipment is utilized to transporting fresh and cold air to the equipment needed to be cooled to reduce the temperature of the equipment needed to be cooled. In particular, the basement of the magnetic stirring device and a fan room of combustion-supporting wind are connected into a whole; the fresh and cold air is pumped to the basement of the magnetic stirring device by utilizing the wind pumping of a combustion-supporting fan of a smelting furnace and reduces the temperature of the basement; at the same time, high temperature air in the basement is used as preliminarily preheated combustion-supporting air and is pumped to a combustion-supporting wind pipe. The energy-saving ventilation method solves the problems that the basement of the magnetic stirring device adopts mechanical and forced ventilation and has high energy consumption, improves the preheating effect of the combustion-supporting wind and meets the requirements on energy saving and consumption reduction.

Description

technical field [0001] The invention relates to an energy-saving ventilation method, in particular to an energy-saving ventilation method for a basement of a magnetic stirring device. Background technique [0002] In industrial production, there are often equipment that need to be cooled, and some need to use higher temperature gas or liquid, which will cause a lot of energy consumption. [0003] In the production of non-ferrous metal casting / smelting workshops, magnetic stirring devices are often used to stir the molten metal in the melting furnace. The magnetic stirring device needs to be arranged at the bottom of the melting furnace to form a basement at the bottom of the melting furnace. Due to the high temperature at the bottom of the smelting furnace and the heat generated by the magnetic stirring device, the working environment temperature of the magnetic stirring device is high, and the magnetic stirring device is very sensitive to the working environment temperature...

AI Technical Summary

Problems solved by technology

Due to the high temperature at the bottom of the smelting furnace and the heat generated by the magnetic stirring device, the working environment temperature of the magnetic stirring device is high, and the magnetic stirring device is very sensitive to the working environment temperature. When the temperature exceeds the maximum temperature it can withstand, it will It affects its magnetic efficiency, which in turn affects the work efficiency, so it is necessary to ventilate and cool the basement of the magnetic stirring device

The method of mechanical forced ventilation is usually used, and its disadvantages are: it is necessary to add a special ventilation fan to supply / exhaust air to the basement, which increases the consumption of electric energy; the hot air drawn from the basement is discharged into the workshop, wasting the preheated air , and affect the working environment of the workshop
