Problems solved by technology

As mentioned above, although the form of water-cooled furnace wall can ensure the long-term use of the furnace lining, it is based on a relatively complete set of industrial processes for equipment processing, installation, use, and maintenance. It is easier in countries with strong industrial foundations. Realization and safe operation, in many areas with energy shortages, relatively weak industrial bases, and project locations with insufficient labor quality and training, the potential safety hazards and risks are also huge
[0040] (3) The physical sensible heat loss of furnace gas and thermal slag discharge is large: due to the high temperature of the discharged synthesis gas and liquid slag, the sensible heat is relatively large. If the sensible heat of these two parts is not recovered, the heat loss will be large
[0041] (4) It is usually intermittent slag discharge, which is inconvenient to operate: if we learn from the unit operation of the iron and steel industry, the slag is discharged periodically instead of continuously, and the continuity of operation is not good
[0042] (5) It is difficult to remove dust from high-temperature furnace gas: the temperature of the initially generated synthesis gas is as high as 1500°C after breaking through the molten pool, and the dust content is relatively large. If there is a large secondary combustion rate in the slag, the synthesis gas may The higher temperature brings great difficulties to cooling and dust removal
[0043] (6) Gasification of hydrocarbons other than coal: the gasifiers developed for different types of coal are relatively mature, but it is difficult to use gasifiers for different types of coal
However, other kinds of organic matter, especially those with complex sources and large fluctuations in composition, such as biomass and domestic waste, are difficult to adopt coal gasification equipment and processes

Embodiment 1

[0083] After the organic particles are injected into the molten iron bath-slag bath at high speed, the hydrocarbons in the organic matter are rapidly cracked by heat, the carbon chain and the hydrocarbon chain are broken, and the hydrogen atoms are combined into hydrogen molecules. The carbon dissolves in the molten iron, and the molten iron can be dissolved The carbon content of the Fe-C alloy is between 3-5%, which greatly reduces the melting point of the Fe-C alloy, and the melting point of the iron-carbon alloy melt with 4.3% carbon is as low as 1148 ° C, such as figure 1 The Fe-C state diagram is shown. This makes it possible to maintain the iron-based alloy as a liquid melt above 1250°C in industry, which not only reduces heat loss, but also ensures the extension of the life of the furnace lining and spray gun. This temperature is relatively thorough for the cracking and gasification of organic matter. However, considering the melting point and fluidity of the slag liqui...

[0115] combine Figure 7 , Figure 8 , Figure 9 be explained.

[0116] The liquid level regulating furnace 101 communicates with the bottom of the gasification furnace 201 through a communication pipe 109 . The upper part of the liquid level adjustment furnace 101 is connected with a molten iron injection tank 106, and the molten iron with a pre-melted temperature of 1200-1700°C is put into the molten iron bag 113, and the molten iron is injected into the molten iron from the molten iron bag 113 In the injection tank 106, the molten iron flows into the liquid level regulating furnace 101. As the amount of molten iron gradually increases, the connecting pipe 109 is also filled with molten iron, and the liquid level gradually rises to the bottom of the gasification furnace 201.

Description

technical field [0001] The invention belongs to the field of chemical industry, and the classification number is C10J3, in particular to a double molten bath organic solid waste injection gasification device. Background technique [0002] Since human society entered industrialization, the garbage and waste discharged from social life and production process have been increasing and accumulating in astonishing quantities, which has become a major ecological and environmental problem that human society must face. Although people use landfill, incineration, composting and other methods to deal with solid waste, especially the organic matter in it, the commonly used treatment methods are either difficult to cope with the rapid growth of solid waste in terms of speed and quantity, or are in the process of processing New secondary pollution is likely to be generated during the process, either due to the high cost of treatment, or due to the limitation of land capacity and so on, it...
