Technical field
This utility model relates to a kind of preheating device, the dress of a kind of closed-loop tail gas heat quantity preheated metallic furnace charge
Put.
Background technology
Along with United Nations Climate Change Conferences in 2015 highly visible are held in Paris, by countries in the world to low-carbon economy
Concern pushed a new peak to.Low-carbon economy be characterized with low energy consumption, low emission, low stain put into practice economic society can
The target of sustainable development.But, the economic development of developing country again will be through the development rank of greater energy consumption and disposal of pollutants
Section, this is that the industrial structure is determined.The China rapid growth period of being in economic, it is by height greatly that its growth has
Power consumption, the secondary industry of high pollution bring.It is reported, the greenhouse gas emissions of China have occupied the second in the world.Along with China
Economic and social development, energy-saving and emission-reduction have become as the common recognition of the whole society and the binding indicator of government work.
Casting industry belongs to an important industry in national economy, is also the big power consumer of mechanical industry, and energy consumption is high, energy
Source utilization rate is low, seriously polluted, deficiency in economic performance etc. constrains the development of casting industry.Reasonable energy utilization, does a good job of it joint energetically
The about energy is a vital task of casting industry.And the energy consumption of foundry goods melting part accounts for the 50% of castings production total energy consumption,
The efficiency of smelting furnace decides the energy utilization rate of casting industry.Present stage China's casting smelting technique there is substantial amounts of heat energy quilt
Flue gas is taken away, and the UTILIZATION OF VESIDUAL HEAT IN potentiality of casting smelting stove are the biggest.And China's smelting furnace majority is provided without waste heat utilization equipment at present,
Even if part smelting technology have employed waste heat utilization equipment, but utilization rate is low, and energy-saving effect is inconspicuous.How to improve waste heat profit
With rate and then the raising smelting furnace thermal efficiency, reach energy-saving and emission-reduction purpose and be always the problem that this area is paid close attention to.
Utility model content
