The present invention relates to a cremation system, and more specifically, by constructing an intelligent cremation system using data mining multivariate statistical analysis including a cremation furnace that can respond to various cremation objects to maximize the combustion efficiency of the cremation furnace. It is a technology related to an intelligent high-efficiency eco-friendly cremation system that shortens time, reduces fuel consumption, suppresses emission of environmental pollutants, and enables unmanned operation.

The prior art related to the cremation system includes a cremation furnace for cremating a corpse as shown in FIG. 1; An environmental treatment facility including a dust collector for treating harmful gases generated in the combustion furnace; Consists of a recycling facility including an air preheater for high-temperature waste heat recovery.In particular, most cremation furnaces installed in Korea, unlike cabinet type cremation furnaces, which are heat storage type, have a short funeral time, and according to cultural characteristics, energy consumption is large, which is an intermittent type cremation. A furnace is adopted, and accordingly, an energy-saving combustion control system and an eco-friendly cremation system that can further minimize air pollution emissions are required.

More specifically, the form of a cremation furnace of the prior art widely known in Korea is the cremation furnace of Sehwa Industrial Company shown in Fig. 2(a), the cremation furnace of B&L company shown in Fig. 2(b), and the cremation furnace of Fig. 2(c). There is a cremation furnace, Miyamoto's cremation furnace method shown in Fig. 2(d), and these cremation furnace methods have the process characteristics and advantages and disadvantages of Table 1 below.

Among the cremation furnaces of Table 1, the cremation furnaces of the rest of the way except for the cremation furnace of B&L company are cremated by moving the tube inside the main combustion chamber in a state where the tube is placed on the inside of the furnace from the front cooling room provided at the entrance of the cremation furnace. The ashes are taken out of the main combustion chamber to receive the ashes from the cooling front chamber, and this method has the effect of providing comfort to the bereaved by treating the mouth and bones in the presence of the bereaved family.

However, since the in-furnace truck stays in the furnace during combustion, the consumption of the in-furnace truck is large, and the maintenance cost is large, and a large amount of unburned powder may exist in the exhaust gas due to temporary incomplete combustion during the incineration process. A reburning chamber is installed at the rear end of the burnout and the incomplete combustion remains are treated by maintaining it above a certain temperature using a dedicated burner with excessive air supply.

In addition, since a certain amount of dust may be included in the exhaust gas of the high-temperature recombustion chamber, the temperature is lowered through the primary air mixer, and a dry cyclone is installed at the rear end as a dust recovery facility to primarily remove dust in a high temperature state. Are being collected.

After that, while lowering the exhaust gas temperature at the rear end of the cyclone, an air preheater and a gas cooler are installed to recover the high-temperature exhaust gas heat and preheat the combustion air supplied to the burner, and the exhaust gas is attracted to the rear end of the bag filter. Although the burner combustion control in the furnace, such as installing an exhaust fan, and the stabilization of the cremation furnace operation are being pursued, the control system is dependent on the operator's judgment, and thus, high-efficiency combustion control and operation stabilization according to the combustion situation are insufficient.

In recent years, as the social interest in the discharge of environmental pollutants has increased, the additionally installed exhaust gas management device is a dioxin removal device by a platinum catalytic reactor in the exhaust gas post-treatment facility, a white smoke prevention device for preventing white smoke, and a harmful for reducing NOx. A gas catalyst is installed to manage environmental pollution due to exhaust gas discharged from the combustion furnace, but the control of the exhaust gas post-treatment facility according to the change of exhaust gas is also dependent on the operator's judgment, so it is optimal to respond to real-time changes in cosmetic facilities. Due to insufficient control, environmental pollution problems still arise.

That is, in the cremation system of the prior art, the cremation facility control system including the cremation furnace combustion and exhaust gas post-treatment facility is operated based on a generally known PLC-HMI (Programmable Logic Controller-Human Machine Interface), and all work results are Since there is only a real-time monitoring function and the appropriateness of the operation of the cosmetic equipment is dependent on the operator's judgment, there is a problem that cannot cope with environmental changes.

In addition, as is widely known, domestic funeral culture has undergone a rapid change from burial method to cremation and natural field along with rapid industrialization and urbanization, and the national cremation rate in 2017 accounted for 84.6%, so measures such as the establishment of cremation facilities are necessary. As cremation facilities are recognized as environmental pollution and hate facilities, it is difficult to establish or expand facilities, so it is urgent to prepare a more eco-friendly cremation system that can solve this problem.

The present invention is to solve the above-described problem, based on artificial intelligence analysis software based on data mining technique, energy is saved through optimal combustion control, and abnormality of each part of cosmetic equipment through abnormal diagnosis and operation status monitoring system. It aims to provide an intelligent, high-efficiency eco-friendly cremation system that achieves unmanned operation of cremation facilities by automatically diagnosing and operating conditions, and secures convenience in maintenance and operation and operational stability.

Since the weight of the combustion object burned in the crematorium acts as an important operating variable for shortening the combustion time, the load cell 17 is installed in the tube transport vehicle 100 and the measured weight of the combustion object is automatically transmitted to the central operation room for combustion control. It is used as the operation data of the system.

In addition, the combustion control system is a simple burner control based on the temperature in the furnace, and incomplete combustion is inevitable when the combustion of accessories and wooden pipes occurs rapidly.In order to solve this, not only the temperature of the cremation furnace, but also the amount of fuel, combustion air, and oxygen Various measuring devices are installed to measure concentration and differential pressure.

In the cremation industry, when the corpse is transferred to the crematorium through a funeral car, the corpse is transported to the crematorium (1) using a tube transport vehicle, and the corpse is transferred from the front room of the cremation furnace to the in-house cart and brought into the main combustion room. It is executed by starting the system in the central operation room PC (19) or the field control panel (18).

When the intelligent high-efficiency eco-friendly makeup system according to the present invention is organized, based on the data mining analysis software and the intelligent data mining abnormality diagnosis and monitoring system software operated based on the data mining analysis software, commercialized data mining analysis software is selected and utilized. The interface from the user's point of view acquires and processes various types of complex operation data, and through data visualization, the person in charge directly analyzes the data to form a combustion control system to provide the best operation analysis work and maintenance environment. By forming a system for diagnosis of abnormalities and operation status through mining, real-time operation data of the crematorium is continuously accumulated and analyzed, and based on the analyzed empirical data, the cremation operation can be performed by controlling it under unmanned conditions.

To form.

That is, the intelligent high-efficiency eco-friendly cremation system according to the present invention not only diagnoses abnormalities by showing the current cremation operation status on the cremation furnace to the operator in real time, but also predicts the condition of facilities necessary for future facility management. While providing a guide to manage maintenance, all collected data in the operation process are stored and the empirical model equation is upgraded at regular intervals, so that the more accumulated data, the better the control level, and responds even when exposed to unexpected unstable disturbances. It was formed by utilizing big data analysis software that accompanies an artificial intelligence function that enables stable cremation operation while improving ability.

[Gas flow-based control model equation]

Fuel flow rate = regression coefficient: 15.9413-0.6865 * cremator pressure-0.0358 * main combustion chamber temperature + 0.1027 * combustion air flow rate + 0.0036 * excess air flow rate-0.5693 * oxygen concentration-0.0384 * air mixing temperature

During the process of cremation, the control pattern according to the shape of the cremated body (general, frozen, burial, ultra-frozen, etc.) is once again determined through the state of the corpse and the combustion state of the accessories in the high smoke state reached 10 minutes after the start of cremation. The gas flow rate-based control model equation for setting the temperature to the appropriate temperature is adjusted.

In the low-study operation of the gas flow-based control model, a certain amount of gas flow is continuously input when the combustion chamber temperature is 850℃ or less, and the combustion chamber temperature It is controlled to operate with temperature-based proportional control from when is above 850℃,
In the high-study operation of the gas flow rate-based control model, when the combustion chamber temperature is less than 900°C, the gas flow rate is gradually increased and input, and the combustion chamber temperature is controlled to operate with temperature-based proportional control from 900°C.
Intelligent in that the operating conditions are additionally changed to increase the amount of excess air when the oxygen concentration decreases to less than 12% during the high-study period, and when the final combustion is confirmed, the main combustion burner and the reburning burner are digested to end makeup. High-efficiency eco-friendly makeup system.
