Description

Garbage incinerator

The utility model relates to a waste incineration device, which is a waste incinerator.

In modern life, tens of thousands of tons of domestic waste are produced every day. How to dispose of this large amount of rubbish has always been a problem of great concern to people. At present, the methods for dealing with domestic waste mainly include landfill, incineration and biotransformation. Among them, the incineration method can completely eliminate the pollution of garbage to the environment, but because there is no garbage incineration device with high efficiency, low energy consumption, and a large amount of garbage that can be completely burned, most cities now mainly use centralized landfills. Garbage disposal methods. According to statistics, a city with about 10 million people has 9,000 tons of garbage to be disposed of every day, and the establishment of a garbage landfill site not only requires a large investment, but also takes up a large area of land, and the usable period is not long, and it also seriously affects the quality of the surrounding areas. Sanitation. So using incineration to dispose of garbage is a better way. The existing solid waste incinerator is mainly composed of a furnace body, a blower and its air supply pipe, flue, dust collector and chimney, and any kind of incinerator is equipped with a burner that uses fuel oil or combustible gas. Or electric heating device to incinerate waste. Existing incinerators have relatively complex structures, consume a large amount of energy, and their incineration effects are not ideal, especially when they are used to incinerate a large amount of domestic waste, they are not easy to burn out, and secondary pollution to the environment will occur.

The purpose of this utility model is to provide a garbage incinerator without external fuel, so that the society can widely use the incineration method to completely dispose of domestic garbage, and achieve the purpose of saving energy and burning thoroughly.

As we all know, as far as its domestic waste is concerned, although there are all kinds of wastes, including hard, soft, dry, wet, and some are even severely rotten wastes, except for metal and construction waste, most of them are organic combustible substances and made of waste. It emits flammable gases. The utility model utilizes the heat source contained in the household garbage to burn the household garbage itself. In order to realize this solution, the utility model mainly makes major improvements to the structure of the furnace body, the furnace and the chimney. Air supply pipe, flue, dust collector and chimney, but in this design, the outer casing of the furnace body is a compartment structure composed of an external overall structural heat-resistant steel plate and an internal heat-resistant steel plate. The furnace is composed of high-temperature resistant bricks, and air supply pipes arranged vertically and horizontally are embedded on the surrounding walls of the furnace. The chimney in this design is also provided with a horizontal flue at the top, and a vertical flue is respectively provided at both ends of the horizontal flue, forming a double-row smoke chimney at the top; There are densely arranged water spray hole devices, and a suction device is respectively connected and fixed at the bottom of the vertical flue.

The utility model has the advantage that since the walls around the hearth made of high temperature resistant bricks (which can withstand high temperatures of 1200°C) are embedded with air supply pipes arranged vertically and horizontally, and the air sent in is already in the outer shell interlayer and The furnace wall has been preheated, so the air blown out from the air supply pipe not only has a higher temperature, but also has a higher wind pressure and a larger air volume. The combustion-supporting air sent into the furnace not only supports combustion, but also Its "jet" in the entire furnace also plays a role in loosening the garbage, so that the garbage can get enough oxygen to burn, and the combustion is relatively complete. The utility model is described in detail. In the utility model, the top double-row smoke chimney with spray function can further clean the dust particles brought out by the smoke by spraying water to cleanly discharge the smoke, and can avoid a large amount of dust and smoke from staying in the chimney pipe , On the other hand, the suction device located at the bottom of the vertical flue can improve the emission efficiency of the chimney.

Embodiment of the utility model is as shown in the accompanying drawings. Below in conjunction with accompanying drawing, the utility model is described in detail.

See Figure 1 first. Seen from the figure, the utility model mainly consists of a body of heater 1, a blower and an air supply duct thereof, a flue, a dust collector 2 and a chimney 3. A horizontal flue 4 is provided at the top of the chimney 3, and a vertical flue 5 is respectively provided at both ends of the horizontal flue 4, forming a top double-row smoke chimney. As can be seen from Fig. 2 and Fig. 3, the outer casing of the furnace body 1 in the utility model is a compartment structure composed of an external overall structure heat-resistant steel plate 7 and an internal heat-resistant steel plate 8, and a high-temperature resistant Bricks 6 constitute the hearth, and air supply pipes 10 arranged vertically and horizontally are embedded on the surrounding walls of the hearth. Each air supply pipe 10 passes through heat-resistant high-temperature bricks 6 and internal heat-resistant steel plates 8 to communicate with the outer layer 11 of the outer shell. Number 9 among the figure is the through hole that is opened on the steel plate 8 and communicates with the air supply pipe 10 .

As can be seen from Figure 4, the chimney 3 in the utility model is also provided with densely arranged water spray hole devices 12 above the horizontal flue 4 at the top of the utility model, and is respectively connected and fixed at the bottom of the vertical flue 5. Aspirator 13.
