Description

A magnetized garbage pyrolysis station

technical field

The utility model relates to garbage treatment equipment, in particular to a magnetized garbage pyrolysis station which can better purify the flue gas produced by garbage incineration.

Background technique

With the rapid development of urban construction and new rural construction in our country, the output of domestic waste is increasing day by day. Direct landfill not only consumes a lot of transportation capacity, but also takes up precious land resources. The most troublesome sewage leakage and odor The evaporation of water will pollute the world, not only harming the present, but also harming future generations.

In rural areas and suburbs, it is scattered and directly incinerated in garbage bins, often with black smoke billowing, causing serious air pollution. In response to the above situation, the state has invested a lot of human and financial resources, and has made long-term and unremitting double efforts in scientific research and implementation for the treatment of domestic waste. Facilities for incinerating domestic waste and using them for power generation have been established in first- and second-tier cities. However, large-scale and more advanced domestic waste treatment equipment is basically technology imported from Europe, the United States, and Japan. Although it can operate normally, the construction investment is large and the operating cost is high, so it is difficult to popularize. There are many kinds of technical solutions to overcome domestic waste, including adding coal, oil, and steam to domestic waste for direct incineration, processing domestic waste into charcoal particles, and using a gasifier to treat waste. These technologies are either over-invested and costly to operate, or are immature and cannot function properly. Therefore, the vast majority of domestic waste in our country still adopts the original treatment method of direct landfill or direct incineration, but direct landfill will occupy land resources, and direct incineration will often billow black smoke and produce a large amount of harmful gas. It will cause serious secondary pollution to the air.

detailed description

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in detail as follows:

Referring to the accompanying drawings 1-3, a magnetized garbage pyrolysis station includes a pyrolysis furnace 1, a feeding mechanism, and a control cabinet 2. It is characterized in that the flue gas discharge pipe 19 of the pyrolysis furnace is sequentially installed with Condensate water tank 3, water bath tank 4, demister tank 5, plasma dedusting and deodorization tank 6, secondary pyrolysis chamber 7, the specific structural features and functions of each component are as follows:

Pyrolysis furnace: as shown in accompanying drawing 3, the body of furnace of described pyrolysis furnace is provided with turbulence pipe 8, and the entrance of turbulence pipe is provided with the turbulence valve 9 for controlling turbulence pipe switch, and turbulence pipe A rare-earth permanent magnet magnetizer 10 is installed at the entrance, an insulation layer 11 and a refractory layer 12 are arranged around the inner wall of the furnace, a magnetized wall 13 of high platinum composite material is arranged around the outer wall of the furnace, and a magnetized wall 13 of high-platinum composite material is arranged on the outer wall of the furnace. The fume-gathering hood 14 that the space in the furnace furnace body is connected. The bottom of the pyrolysis furnace needs to be raised to a certain height. The function of the turbulence pipe is to open the turbulence valve during the process of garbage incineration, so that oxygen absorption occurs in the furnace body, and turbulent airflow is generated in the furnace body, so that the speed and efficiency of garbage incineration are higher. The function of the rare earth permanent magnet magnetizer is to magnetize the air inhaled from the turbulence tube, and pass a small amount of magnetized air into the pyrolysis furnace (the function of the high platinum composite material magnetization wall is also to properly magnetize the air and garbage in the furnace, The high-platinum composite material magnetized wall is fixed on the pyrolysis furnace body by screws), so that the combustibles in the solid waste to be processed and the combustibles produced by pyrolysis are partially burned, and the heat generated is the organic matter in the solid waste. Pyrolysis, because the magnetized air makes the object to be magnetized indirectly, which reduces the energy required for pyrolysis and improves the efficiency of pyrolysis. Therefore, pyrolysis and gasification can be realized at a low temperature of 350 ° C, thus basically avoiding the generation of dioxins. produce. The refractory layer is set on the outermost side of the furnace body to prevent the furnace body from being deformed or even melted due to the high temperature in the furnace. The insulation layer is set between the refractory layer and the furnace body wall to effectively maintain the incineration temperature in the furnace. The function of the fume gathering hood is to gather the rising flue gas produced by incineration and enter it into the condensate tank.

The working principle of the pyrolysis furnace: pour the garbage into the garbage pyrolysis furnace, and use combustibles to ignite the fire at the bottom of the garbage furnace. Under the condition that each air flow regulating valve is opened, oxygen absorption occurs during the pyrolysis process of organic waste in the cavity, and the air is magnetized through the oxygenation pipeline and enters the waste pyrolysis chamber to support combustion and generate turbulent flow, which accelerates the thermal decomposition of organic waste.

The feeding barrel is installed on one side of the pyrolysis furnace through a bracket 18 and connected with a heat pipe through a pipeline. The top of the furnace is connected. When putting the garbage into the pyrolysis furnace for incineration, first pour the garbage into the feeding bucket, and then start the motor connected to the feeding mechanism. When the loading barrel is lifted to the position of the upper hopper, the garbage in the barrel is automatically poured into the upper hopper, and the upper hopper sends the garbage into the pyrolysis furnace through the pipeline. The connection between the pipeline and the pyrolysis furnace is provided with a Switch, during the working process of the pyrolysis furnace, this opening is in the closed state. At the same time, the garbage in the upper hopper can freely fall into the pyrolysis furnace through the inclined pipeline, or can be pushed into the pyrolysis furnace through the parallel pipeline through the hydraulic cylinder.

Control cabinet: The control cabinet is used to control the operation of the feeding mechanism and the entire equipment, connect with each component through the circuit and perform operations on each component.

There is water in the condensate tank, and the flue gas produced by incineration enters from one end of the condensate tank, and the other end is discharged through the pipe into the water bath tank. Water-soluble substances in the air are absorbed and purified.

Water bath box: The water bath box is a common water bath box commonly used in the market. The water bath box is equipped with a water pump to provide high-pressure water for the work of the water bath box. The high-pressure water purifies the water-soluble substances in the flue gas, and at the same time absorbs sulfur, phosphorus and other harmful substances in the flue gas to achieve the effect of secondary purification of the flue gas. The installation position of the water bath is lower than that of the condensate tank.

Demist box: the demist box is a closed box with a plurality of PVC boards inside the box, and the two ends of the box are respectively connected with the water bath box and the plasma dust removal and deodorization box through pipes.
