Abstract
Description
Technical Field
[0001] This utility model relates to the field of cremation furnace technology, and in particular to a high-efficiency, multi-fuel, environmentally friendly, and intelligent cremation furnace. Background Technology
[0002] With the acceleration of urbanization and the increasing demands for ecological environmental protection, traditional cremation equipment has gradually revealed a series of problems in terms of environmental performance, combustion efficiency, and pollutant control. In particular, the cremation of animal carcasses and medical waste produces large amounts of toxic and harmful gases, such as dioxins. These substances are extremely toxic and persistent, classified as Group 1 carcinogens by the International Agency for Research on Cancer, posing long-term harm to human health and the environment.
[0003] Traditional crematoriums employ direct-vent flue gas emission systems, resulting in short residence times of flue gas within the furnace (typically less than 1.5 seconds). This leads to incomplete combustion, low dioxin decomposition rates, and failure to meet environmental standards. Furthermore, traditional equipment suffers from low combustion heat utilization efficiency and severe secondary pollution, making it difficult to meet the requirements of modern environmental protection and sustainable resource development. Therefore, we propose a high-efficiency, multi-combustion, environmentally friendly, intelligent crematorium to address these issues. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-efficiency, multi-fuel, environmentally friendly, and intelligent crematorium.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A high-efficiency, multi-fuel, environmentally friendly, intelligent crematorium includes a crematorium body. A heating device is installed at the upper end of the crematorium body. A conical conveying hood is connected to one end of the crematorium body. Multiple arc-shaped guide plates are fixed at equal intervals on the inner side wall of the conical conveying hood. A gas supply mechanism is connected to one side of the crematorium body. A collection structure is connected to the lower end of the crematorium body. Multiple U-shaped fixing rods are fixed at equal intervals inside the crematorium body. Adjacent U-shaped fixing rods are connected by six mounting plates. Multiple reflectors are installed at equal intervals on the mounting plates and U-shaped fixing rods. Multiple arc-shaped reflective grooves are provided at equal intervals on one side of each reflector. The lower end of the heating device passes through the reflector and extends into the crematorium body.
[0006] Preferably, the gas supply mechanism includes a blower disposed on one side of the cremator body, one end of the blower being connected to a gas supply pipe, a fixed pipe being fixed on one side of the lower end of the cremator body, and nozzles being connected to both sides of the fixed pipe. The nozzles penetrate the side walls of the cremator body and the reflector and extend into the cremator body. One end of the gas supply pipe is connected to one side of the fixed pipe.
[0007] Preferably, the collection structure includes a collection box fixed to the lower end of the cremator body, a collection container extending through one side of the collection box, a placement plate installed at the upper end of the collection box, an opening on the placement plate, and a filter screen installed in the opening.
[0008] Preferably, one end of the conical conveying hood is connected to a discharge pipe.
[0009] Preferably, two covers are hinged to one side of the crematorium body.
[0010] In this utility model, during cremation: 1. Preparation stage: Place the animal carcass or waste to be cremated on the filter screen on the placement plate, close the cover, and start the heating equipment to preheat; 2. Combustion heating stage: The heating equipment starts working, and at the same time the blower delivers oxygen into the furnace through the nozzle to form an oxygen-rich combustion environment. The reflector and the arc-shaped reflector groove work together to evenly reflect the heat to all parts of the furnace, improving the heat utilization rate. 3. Flue gas treatment stage: The flue gas produced by combustion rises in a spiral through the arc-shaped guide plate, increasing the residence time in the furnace. Harmful substances such as dioxins are cracked under high temperature and long residence conditions, with a decomposition rate of up to ≥99.8%. The residue after incineration falls into the collection box. 4. Discharge and Cleanup Phase: The purified flue gas is discharged through a conical conveyor hood and an exhaust pipe. After cremation, the cover is opened, the collection box is removed, and the residue is processed, thus completing the entire process.
[0011] This utility model has the following advantages: 1. The multi-stage reflective structure and the blower system work together to significantly improve combustion efficiency and reduce energy consumption. The improved thermal energy utilization rate means that the fuel consumption per unit of combustion volume is reduced, resulting in significant energy-saving benefits. 2. The flue gas residence time is extended to 3.2 seconds, which is much higher than the 1.5 seconds of traditional furnaces, greatly improving the decomposition efficiency of toxic substances such as dioxins; In summary, this utility model extends the flue gas residence time by using an arc-shaped guide plate, which is much longer than the 1.5 seconds of traditional furnaces, greatly improving the decomposition efficiency of toxic substances such as dioxins. The use of a reflective heating structure improves thermal efficiency and significantly enhances combustion efficiency, thus achieving efficient decomposition and purification of harmful gases.

Multiple arc-shaped guide plates 14 are fixed at equal intervals on the inner side wall of the conical conveying hood 2. The guide plates are made of ceramic composite material to enhance high temperature resistance. The guide plates are arranged in a spiral shape so that the flue gas generated by combustion forms a vortex flow during the upward process, prolonging the residence time of the flue gas in the furnace and facilitating the full decomposition of harmful substances. A gas supply mechanism is connected to one side of the cremator body 7, and a collection structure is connected to the lower end of the cremator body 7. Multiple U-shaped fixing rods 11 are fixed at equal intervals inside the cremator body 7. Two adjacent U-shaped fixing rods 11 are connected by six mounting plates 12.

Combustion heating stage: The heating equipment 10 starts working, and at the same time the blower 6 delivers oxygen into the furnace through the nozzle 13 to form an oxygen-rich combustion environment. The reflector 18 and the arc-shaped reflector groove 17 work together to evenly reflect heat to all parts of the furnace, improving the heat utilization rate. 3. Flue gas treatment stage: The flue gas produced by combustion rises in a spiral through the arc-shaped guide plate 14, increasing the residence time in the furnace. Harmful substances such as dioxins are cracked under high temperature and long residence conditions, with a decomposition rate of up to ≥99.8%. The residue after incineration falls into the collection box 8. 4. Discharge and Cleanup Phase: The purified flue gas is discharged through the conical conveyor hood 2 and the discharge pipe 1. After the cremation is completed, the cover 9 is opened and the collection box 8 is taken out for residue treatment, thus completing the entire process.
