Embodiment 1
[0035] As shown in Figure 1-2: a high-efficiency and environmentally friendly blast furnace gas steam boiler, which includes furnace wall 1, water-cooled wall pipe system 2, steam-water system 3, superheater 4, economizer 5 and platform escalator 6;
[0036] Such as Figure 8-11 As shown, the furnace wall 1 is made of refractory material, and there are four heat collection chambers in it: furnace 11, overheating chamber 12, evaporation chamber 13 and energy-saving chamber 14; furnace hearth 11, overheating chamber 12, evaporation chamber 13 and energy-saving chamber 14 Arrange horizontally in turn (that is, not up and down). The horizontal arrangement can extend the pyrotechnic path and slow down the pyrotechnic flow rate (if it is arranged up and down, the pyrotechnic flow rate will be very fast), so that each water pipe (mainly the water-cooled wall pipe system 2, soda water) System 3, superheater 4, economizer 5) have sufficient contact time with pyrotechnics, which can ach...

The invention provides an efficient and environment-friendly blast furnace gas steam boiler which comprises a furnace wall (1), a water-cooled wall tube system (2), a steam-water system (3), a superheater (4) and an energy-saving device (5). The furnace wall (1) is made of refractory materials and is internally provided with a hearth (11), an overheating chamber (12), an evaporation chamber (13) and an energy-saving chamber (14), and the hearth (11), the overheating chamber (12), the evaporation chamber (13) and the energy-saving chamber (14) are communicated in sequence. The hearth (11), theoverheating chamber (12), the evaporation chamber (13) and the energy-saving chamber (14) are transversely arranged in sequence. The water-cooled wall tube system (2), the steam-water system (3), thesuperheater (4) and the energy-saving device (5) are water pipe systems and are respectively arranged in the hearth (11), the overheating chamber (12), the evaporation chamber (13) and the energy-saving chamber (14). The efficient and environment-friendly blast furnace gas steam boiler can effectively collect blast furnace gas, enables the blast furnace gas to be stably combusted, and meanwhile can output pressure superheated steam, and achieves the purposes of environmental protection and resource full utilization.
Description
technical field [0001] The invention relates to a boiler, in particular to an efficient and environment-friendly blast furnace gas steam boiler. Background technique [0002] At present, the by-products produced in the industrial ironmaking process, that is, blast furnace gas, its main components are: CO, C0 2 , N 2 、H 2 、CH 4 etc., where CO, H 2 、CH 4 etc. are combustible gases, which can continue to burn, especially the CO content will reach about 25%. The discharge of these gases into the atmosphere has the following problems: [0003] 1. Seriously pollute the air, destroy the environment and ecology, and a large amount of discharge will cause serious environmental safety accidents. [0004] 2. The discharge of these combustible gases wastes a lot of energy. Contents of the invention [0005] The purpose of the present invention is to overcome the above-mentioned deficiencies in the prior art and provide a high-efficiency and environment-friendly blast furnace g...
