An environmentally friendly and energy-saving hot blast stove capable of high-power heating and adjustable heating power

Abstract

The invention relates to an environment-friendly and energy-saving hot-blast furnace capable of performing high-power heat supply with adjustable heat supply power. The environment-friendly and energy-saving hot-blast furnace comprises a furnace body, a coal feeding system, a main and auxiliary bed power regulating system, a composite furnace wall system and a light furnace roof and lightweight steel structural system; the furnace body internally comprises a hearth and a settling chamber, a combustion chamber is arranged on the lower part of the hearth, the lower part of the hearth is connected with a blast blower through a blast air box, and the furnace body is provided with a hot smoke pipeline outlet; the coal feeding system is connected with the furnace body; the main and auxiliary bedpower regulating system is arranged in the combustion chamber and comprises a hot-blast furnace combustion chamber main bed, a hot-blast furnace combustion chamber auxiliary bed and a partition wall,the partition wall is connected between a main bed and an auxiliary bed, and the auxiliary bed is higher than the main bed; the composite furnace wall system comprises a fire-resistant wall, a heat-preservation wall, a heat-insulation interlayer and a load-bearing red brick wall which are sequentially arranged from the inside to the outside of the furnace body, and the load-bearing red brick wallis combined with a furnace wall steel structure arranged in the load-bearing red brick wall in a mixed building mode; and the lightweight furnace roof and lightweight steel structural system includesa lightweight furnace roof and a lightweight steel framework. The hot-blast furnace in the application is capable of performing high-power heat supply, the heat supply power can be adjusted as required, and the environment-friendly and energy-saving hot-blast furnace is environment-friendly and energy-saving.

Description

Technical field [0001] The present application relates to the field of mechanical equipment, particularly an environmentally friendly energy-saving hot air furnace capable of adjustable high power heating and heating power. Background technique [0002] The hot air furnace is a device that provides heat in industrial production and drying processes, mainly suitable for combustion powder fuel (eg, pulverized), widely used in chemical, building materials and other industries. [0003] As environmental speech is more and more strong, the requirements for coal-fired equipment are more stringent. Small power coal-fired boilers and hot air furnaces are gradually banned because they do not meet environmental requirements. At present, most domestic industrial hot wind stoves have most production capacity of 30 million cards per hour, mostly face banned pressures. Moreover, as the production scale continues to expand, it is also necessary to support a hot blast furnace that can high power...

Problems solved by technology

Therefore, after increasing the production capacity of the hot blast stove, in order to ensure continuous production when the production is limited during the heating season, the hot blast stove needs to operate under a low-load state. The hot blast stove cannot run stably for a long time
