Problems solved by technology

[0008] 1. The existing ash melting furnace needs to consume a lot of high-quality energy, and the processing cost is high
[0009] 2. Ash slag melting products - the commercial value of slag is extremely low, which cannot make up for energy consumption costs
[0011] Nevertheless, the above-mentioned waste incineration kiln adopts a separate treatment method of pyrolysis of waste plastics in a pyrolysis furnace and direct incineration of other combustibles in an incinerator, which has high requirements for waste classification and pretreatment. Using point-line series connection, the heat transfer method is single, and the distance is relatively long, resulting in large heat loss. In addition, there are many and scattered equipment, and the investment scale is relatively large.

Embodiment 1

[0031] Embodiment 1: with reference to attached figure 1 and 4 , This example is a designed pyrolysis melting furnace with 3 pyrolysis cylinders. The method is to enclose a cavity with heat-resisting refractory walls, and set up three pyrolysis cylinders 2 and a material carrying and transferring device 5 inside. On both sides of the material carrying and transferring device 5; the air inlet at the lower part of the vertical garbage drying heat shrinker 1 is connected with the exhaust fan 6, the gas outlet at the upper part is connected with the flue gas purifier 7, and the blanking port at the lower part is respectively connected with 3 The feeder at the front end of the pyrolysis cylinder 2 is connected, and the rear end of the pyrolysis cylinder 2 is equipped with the slagging device and the exhaust pipe, and the exhaust pipe is connected to the condenser 3, which is then connected to the oil and gas storage device 4 connected. The pyrolysis furnace cavity and the tunnel...

Embodiment 2

[0032] Embodiment 2: with reference to attached figure 1 and 3 , This example is a refitted pyrolysis melting furnace with 2 pyrolysis cylinders. The method is to place two horizontal external thermal pyrolysis furnaces adjacent to the middle and low temperature sections of the tunnel kiln, part or all of the adjacent furnace walls and kiln walls are removed, and the cross-sections are connected and sealed with similar heat-insulating refractory materials, so that The furnace cavity of the pyrolysis furnace and the same temperature section of the kiln cavity of the tunnel kiln communicate with each other; other parts of the equipment are the same as in Embodiment 1. The basis for the modification (including design) is to place the high-temperature end of the tail of the pyrolysis cylinder adjacent to the kiln chamber at the same temperature as the tunnel kiln according to the maximum temperature of the pyrolysis of mixed waste, and adjust the length and diameter of the pyroly...

Embodiment 3

[0033] Embodiment 3: with reference to attached Figure 5 , This example is the method of using the pyrolysis melting furnace described in Example 1 to pyrolyze garbage to prepare ceramics and fuel oil. The bag-broken and crushed mixed garbage falls into the vertical drying heat shrinker 1, and meets the hot air and flue gas sucked by the exhaust fan 6 from the kiln cavity with a temperature lower than 200°C, and the garbage moves downward to complete water evaporation and thermal shrinkage During the process, the flue gas falls into the feeder, the waste heat of the flue gas is fully utilized and initially purified by the adsorption of the material, the evaporated water together with the flue gas enters the flue gas purifier 7 for purification and discharge, and the dry and heat-shrinkable garbage falls to the The feeder, and the re-material sealed oxygen are respectively pressed into the three pyrolysis cylinders 2, and the garbage is cracked by heat and anoxic in the cylind...

Abstract

The invention provides a pyrolyzing and melting kiln and a method for preparing ceramics and fuel oil by pyrolyzing garbage, belonging to the fields of environment-friendly technical devices, biomass energy and novel ceramic materials. The pyrolyzing and melting kiln is formed by communicating equal-temperature sections of a pyrolyzing furnace cavity and a tunnel kiln cavity. In the method, the pyrolyzing and melting kiln provided by the invention is used, a pyrolyzing barrel is taken as a combustion chamber I while the tunnel kiln cavity is taken as a combustion chamber II for burning mixed garbage, garbage pyrolysis and clinker melting are realized synchronously by using heat energy of the garbage, and ceramic and fuel oil products with high added values are prepared directly. An overall economic, efficient and environment-friendly solution is provided for the pyrolysis of materials such as garbage as well as clinker treatment and utilization.

Description

technical field [0001] The invention relates to a pyrolysis melting kiln and a method for preparing ceramics and fuel oil by pyrolyzing garbage, and belongs to the fields of environmental protection technical equipment, biomass energy and new ceramic materials. Background technique [0002] Existing waste disposal methods include landfill, composting, biochemical, pyrolysis, and incineration, among which landfill, composting, and incineration are more mature. The incineration method can realize the "three modernizations" of garbage to a large extent, but the traditional incineration technology has obvious defects in harmlessness. Firstly, it is fundamentally difficult to strictly control the emission of dioxins and heavy metals from incineration; secondly, the land occupation of incineration ash is an increasingly heavy burden for many countries and regions; in addition, the energy efficiency and taste of waste incineration are both low. It needs to be further improved. Th...
