Double-melting-bath organic solid waste blowing gasification device

Abstract

The invention discloses a double-melting-bath organic solid waste blowing gasification device, and belongs to the field of organic solid waste harmlessness, quantitative reduction, resource, and energy processing adsorption, and organic matter ultrahigh temperature monoatomic cracking gasification preparation of synthetic gas. According to the double-melting-bath organic solid waste blowing gasification device, a liquid surface adjusting furnace is communicated with the bottom of a vapourizing furnace, and contains 1200 to 1700 DEG C molten iron based alloy liquid covered with a molten liquidstate slag layer; the gas pressure or liquid amount above the liquid level adjusting furnace is increased, so that the molten liquid surface in the vapourizing furnace is raised, a material spray gunis immersed, immersion spraying of organic particles for gasification into the melting bath is carried out, at the same time, gasification agent oxygen gas and oxygen-enriched air are blew into molten, organic matter gasification into synthetic gas rich in CO and hydrogen gas is realized, most inorganic matters enter into molten slag, and are discharged regularly with accumulation of slag liquid;molten iron liquid amount is maintained to be constant, conversion of most organic waste into clean combustible gas is realized, and the obtained clean combustible gas is taken as fuel gas or chemicalproduct synthetic gas.

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...

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
