Description

Technical Field

[0001] The utility model relates to the technical field of domestic waste treatment, in particular to a domestic waste incineration treatment device. Background Art

[0002] Solid waste generated by people in their daily lives or in activities that provide services for their daily lives, as well as solid waste that is deemed as domestic waste by laws and administrative regulations. It mainly includes domestic waste from residents, market trade and commercial waste, waste from public places, street cleaning waste, and waste from enterprises and institutions.

[0003] With the rapid development of my country's social economy, the acceleration of urbanization and the rapid improvement of people's living standards, the garbage and waste generated in the process of urban production and life have also increased rapidly. The occupation of land by domestic garbage, the pollution of the environment and the impact on people's health have become more and more obvious. In order to realize the industrialization, resource utilization, reduction and harmlessness of urban domestic garbage in my country, we must face the mixed collection, low content and calorific value of recyclable materials, high water content and biodegradable organic content of domestic garbage. In response to these problems, a variety of technologies have also emerged. For example, it is necessary to design a domestic garbage incineration device to treat domestic garbage. Garbage incineration is through appropriate thermal decomposition, combustion, melting and other reactions.

[0004] During the burning process of garbage, due to the complexity and unevenness of the garbage components, many different chemical reactions occur during the incineration process. The flue gas produced includes a large amount of particulate matter, smoke and other chemical substances, which contain components that are directly and indirectly harmful to the human body and the environment, including carbon dioxide, carbon monoxide, nitrogen oxides, sulfides, chlorides, fluorides, heavy metals and other harmful substances. Therefore, garbage incineration facilities must be equipped with flue gas treatment facilities. The dust content in the flue gas generated by garbage incineration is very large. The flue gas needs to be dedusted and then other chemical substances in the flue gas are removed to avoid large particle impurities in the smoke from clogging or damaging the equipment. Even if the garbage incineration flue gas does not contain harmful chemicals, it needs to be dedusted before being discharged to prevent heavy metals, organic pollutants, etc. from being discharged into the environmental medium again to cause environmental pollution and affect human health.

During the process, the dust-containing flue gas passes through the electric field generated by the electricity on the electrostatic rod, and the gas molecules are ionized in the high-voltage electric field to produce charged particles. These charged particles collide with the suspended particles in the air, causing them to be charged. The charged particles are attracted to the electrode with the opposite charge (i.e., the electrostatic rod) under the action of the electric field force, and accumulate on the electrode to form a dust layer. The electrostatic dust removal treatment of the flue gas is then completed. It can remove fine dust with a smaller particle size in the flue gas, and the high purification rate ensures that the flue gas is clean enough after dust removal. BRIEF DESCRIPTION OF THE DRAWINGS

The top of the electrostatic dust removal mechanism is connected to the deodorization mechanism through the air supply pipe, and the deodorization mechanism is also provided with an exhaust fan 3.

[0042] The incinerator of the utility model comprises a feed furnace 4 and a treatment furnace 5. Figure 2As shown, the feeding furnace and the treatment furnace are cylindrical with the same height, and the feeding furnace is arranged above the treatment furnace; a garbage inlet 6 is arranged on the top of the feeding furnace for the entry of domestic garbage, and two hot air pipes 7 are symmetrically arranged on the upper part of the side wall of the feeding furnace; an incineration chamber 8, a transition chamber 9 and an evaporation slag chamber 10 are connected from top to bottom in the treatment furnace;

Figure 3 and 4 As shown, an ignition port 11 and four oxygen supply pipes 12 are provided on the side wall of the treatment furnace corresponding to the incineration chamber. The four oxygen supply pipes are evenly arranged along the circumference of the treatment furnace and are arranged in the cylindrical part of the incineration chamber. The ignition port is connected to the inclined part (inverted truncated cone part) of the incineration chamber and is located below the oxygen supply pipe. When igniting, the ignition port is connected to the burner, and the burner ignites and burns the garbage in the combustion chamber through the ignition port. Most of the garbage is mainly burned in the inverted truncated cone part of the incineration chamber and the top of the cylinder forming the transition chamber. The ash produced after combustion is discharged to the evaporation slag chamber through the transition chamber.

[0044] The transition chamber 9 is formed by a cylinder 13, the top of the outer side of the cylinder is connected to the bottom of the incineration chamber, and the inner side forms a transition chamber.

At the beginning of combustion, part of the garbage burns in the transition chamber, and the ash produced after combustion and the ash produced by incineration in the incineration chamber are gradually accumulated in the transition chamber. Therefore, most of the garbage is burned in the incineration chamber.

[0045] The oxygen supply pipes on the incineration chamber and the transition chamber are connected to the blower to input the air with high oxygen content from the outside into the furnace to assist combustion, so that the garbage in the furnace burns more fully and comprehensively. The oxygen supply pipe located in the transition chamber first inputs air into the interlayer 14, and the air in the interlayer then enters the transition chamber through each oxygen supply port 15 to assist combustion.

[0046] The blower and the burner are both prior art, and the introduction of air and ignition and combustion through the blower and the burner are both prior art, so they are not described here and are not shown in the accompanying drawings.

[0047] Two smoke outlet pipes 16, a slag outlet furnace door 17 and a burning barrier device are arranged on the side wall of the processing furnace 5 corresponding to the evaporation and slag discharge chamber.

The middle part of each rotating rod evenly extends a number of mutually parallel blocking members 20 in the same direction (when there is no counterweight, the blocking members face downward). By rotating the two rotating rods, the blocking members on the two rotating rods can be brought close to each other to form a blocking surface 21 provided at the bottom of the transition chamber. When the blocking surface is formed, counterweights 22 are provided at both ends of the blocking rod to ensure that the blocking surface is formed to block the garbage from burning.

[0050] The height of the treatment furnace and the feeding furnace of the utility model are both 5m. The inclination angle of the inclined edge at the bottom of the incineration chamber is 145 degrees.

When there is too much sewage, it will be discharged from the impurity removal overflow port into the overflow box. The liquid sprayed by the impurity removal nozzle has water pressure and can be repeatedly reflected in all directions in the impurity removal barrel, so it can eventually cover the entire impurity removal barrel to remove impurities from the flue gas.

[0071] S23. Cyclone dust removal: The flue gas forms a cyclone through the cyclone plate 39 at the position of the smoke inlet pipe of the dust removal barrel, and at the same time, due to the suction of the exhaust fan 3, it rises rapidly, and some of the dust and residual water vapor from the secondary cleaning are trapped in the dust removal barrel. The flue gas passing through the cyclone dust removal mechanism enters the air inlet box 43 or the deodorizing box 55 of the electrostatic dust removal mechanism through the air supply pipe;

[0072] S24. Electrostatic dust removal: The electrostatic rod 48 and the distribution box 51 are electrically connected in the electrostatic dust removal mechanism, and an electric field is generated in the electrostatic upper box 41, the electrostatic lower box 42 and the electrostatic tube 45. The flue gas entering the electrostatic dust removal mechanism enters from the air inlet box, passes through the electric field in the electrostatic lower box, the electrostatic tube and the electrostatic upper box in sequence, and electrostatic dust removal is performed. After electrostatic dust removal, the flue gas rising to the electrostatic upper box is sent to the deodorization box 55 through the air supply pipe 2;

[0073] S25. Deodorization treatment: The flue gas directly sent from the dust removal barrel 33 into the deodorization box 55 and the flue gas entering the deodorization box 55 after the electrostatic dust removal treatment are absorbed and deodorized by the deodorant 56 in the deodorization box, and the deodorized flue gas is extracted by the exhaust fan 3, that is, the flue gas treatment after the incineration of domestic waste is completed.
