Waste heat utilization energy-saving smelting furnace

Abstract

The invention belongs to the field of energy conservation of smelting furnaces, and particularly relates to a waste heat utilization energy-saving smelting furnace, which comprises a furnace body; and base is fixedly connected to the lower surface of the furnace body, and a blow-off pipe is arranged at the top of the base. According to the waste heat utilization energy-saving smelting furnace provided by the invention, by arranging a water circulation mechanism, when equipment is used, cooling water is injected into a water tank through a water injection pipe, a heat absorption mechanism ejects open a one-way valve along with rising of the temperature in the equipment, and the cooling water flows into a heat absorption mechanism from a ceramic heat insulation pipe and flows into a heat preservation pipe through the heat absorption mechanism, the other part of cooling water downwards flows to the top end of a telescopic rod along a backflow pipe, the telescopic rod extends, the expansion density of hot water in the telescopic rod is reduced and the hot water upwards flows along with the rising of the water temperature, and the cold water downwards flows on the contrary, the movement of the telescopic rod is controlled through residual heat leaked by the device according to the principle of thermal expansion and cold contraction, and then the work of a supporting mechanism is controlled, the problems that waste heat of a traditional smelting furnace is directly discharged outwards, and resource waste and environmental pollution are easily caused are solved.

Description

technical field [0001] The invention belongs to the field of furnace energy saving, in particular to an energy-saving furnace utilizing waste heat. Background technique [0002] In the field of traditional chemical metallurgy, in order to obtain raw materials that meet the requirements, it is often necessary to melt solid raw materials in a high-temperature furnace. The heat sources of the furnace are mainly three types: oil injection type, high-voltage current type, and coal type. Low is widely used. [0003] When the traditional coal-type furnace is working, the internal coal will harden when it is left to burn for a long time, and the oxygen supply of the internal coal will stop, which will make the coal burn insufficiently. The insufficiently burned coal will not only cause waste of fuel, but also cause blockage Inside the equipment, at the same time, coal combustion will generate a lot of heat and coal ash will leak out, which will pollute the environment while increas...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an energy-saving furnace for waste heat utilization, which solves the problem of insufficient internal coal combustion when the traditional coal-type furnace is in use, which will cause equipment blockage internally, pollute the environment externally, and increase the use cost. question
