Description

Technical Field

[0001] The utility model relates to the technical field of garbage incinerators, in particular to a secondary air arrangement device for an incinerator. Background Art

[0002] At present, there are many types of garbage incinerators in use in my country, mainly fluidized bed incineration boilers and mechanical grate incinerators. Mechanical grate incinerators have perfect and reliable technology, large capacity, strong garbage adaptability, and can burn garbage with low calorific value and high moisture content. They are the main development direction of garbage incinerators at present. In mechanical grate incinerators, they can be divided into drum grates, horizontal grates, and inclined grates according to the grate. In the actual operation of garbage incineration power plants, it is clearly stipulated that the flue gas must stay in the oxygen concentration>6% and temperature>850℃ for>2s. The secondary air arrangement is related to the airflow organization in the furnace, which plays a vital role in ensuring stable combustion in the furnace and burning out the garbage.

[0003] However, it still has some disadvantages. For example, when the traditional garbage incinerator is injecting secondary air, due to the small number of injection nozzles, the distribution range of the injected oxygen is limited, which makes the garbage incineration time longer and the efficiency low. In addition, a large amount of chlorine-containing compounds will be produced during the incineration process of garbage. The hot air generated in the incinerator flows back into the air duct, and the air duct will suffer from severe chlorine corrosion.

[0004] In order to solve the above problems, this application proposes a secondary air arrangement device for an incinerator. Summary of the invention

[0005] The purpose of the utility model is to provide a secondary air arrangement device for an incinerator, so as to solve the problems in the prior art of conventional garbage incinerators proposed in the above background technology that when secondary air is injected, due to fewer injection nozzles, the distribution range of the injected oxygen is limited, resulting in a long garbage incineration time and low efficiency, and a large amount of chlorine-containing compounds will be generated during the incineration of garbage, and the hot air generated in the incinerator will flow back into the air duct, causing the air duct to suffer serious chlorine corrosion.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a secondary air arrangement device for an incinerator, comprising an incinerator, the upper outer surface of the incinerator is fixedly connected to a smoke outlet pipe, the outer surface of one side of the incinerator is communicated with a primary air duct, the outer surface of one side of the incinerator is fixedly connected to a connecting pipe, the outer surface of one side of the connecting pipe is fixedly connected to a blocking component, the outer surface of one end of the primary air duct is fixedly connected to a fan, the outer surface of one end of the fan is fixedly connected to a secondary air duct, and the secondary air duct is located on the left and right sides of the incinerator, and the secondary air duct is communicated with the blocking component.

[0007] Preferably, a nozzle is fixedly connected to the outer surface of one end of the connecting pipe, and the number of the nozzles is six groups, and the nozzles are evenly distributed in the inner cavity of the incinerator.

[0008] Preferably, the blocking assembly includes a blocking buffer box, a box cover, a sleeve, a telescopic rod, a connecting rod, a baffle and a movable connecting block, the number of the sleeve, the telescopic rod and the movable connecting block are two groups, and the blocking buffer box is fixedly connected to the outer surface of one side of the connecting pipe.

[0009] Preferably, a box cover is fixedly connected to an upper outer surface of the blocking buffer box, and a sleeve is fixedly connected to an outer surface of one side of the blocking buffer box.

[0010] Preferably, the inner wall of the sleeve is movably connected with a telescopic rod, the lower end outer surface of the box cover is movably connected with a connecting rod, and the lower end outer surface of the connecting rod is fixedly connected with a baffle.

[0011] Preferably, a movable connection block is fixedly connected to an outer surface of one side of the baffle, and the movable connection block is movably connected to the telescopic rod, and the baffle and the movable connection block are located in the inner cavity of the blocking buffer box.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model has multiple groups of nozzles, when secondary air is injected into the incinerator, the oxygen injected into the incinerator is evenly injected into the incinerator through the multiple groups of nozzles, so that the garbage in the incinerator is quickly and fully burned, and the efficiency of the incinerator when burning garbage is improved.

[0014] The utility model provides a blocking component. When oxygen is sprayed into the blocking buffer box through the fan and then sprayed into the incinerator, the baffle in the blocking buffer box will be separated from the air duct at one end of the blocking buffer box under the blowing of wind force, and the oxygen will be injected into the incinerator. When the hot air generated in the incinerator flows back to the air duct, the baffle in the blocking buffer box will block the air duct under the pressure of the hot air, preventing the hot air generated in the incinerator from flowing back to the air duct and causing serious chlorine corrosion to the air duct, thereby effectively preventing the chlorine generated in the incinerator from corroding the air ducts on both sides of the incinerator.
