Description

Technical Field

[0001] The present invention relates to the technical field of environmental purification, and in particular to a manure incineration system; in addition, the present invention also relates to a manure incineration process method. Background Art

[0002] Traditional toilets rely on flushing systems to flush excrement into the sewer. Excrement enters the septic tank through the sewage pipe, and then the supernatant enters the city's sewage network and finally flows into the sewage treatment plant. In the sewage treatment plant, excrement undergoes a series of complex physical, chemical and biological treatment processes. First, larger solid debris is removed by physical means such as screens, and then sedimentation is carried out so that the suspended solids in the sewage settle to the bottom of the tank to form sludge. Then, through biological treatment, microorganisms are used to decompose the organic matter in the sewage. The treated sewage will not be discharged into natural water bodies until it meets the discharge standards, and the sludge will be further processed, such as anaerobic digestion, dehydration and other operations. Some sludge may be used for agricultural fertilizers and other purposes, but the harmful substances in it need to be strictly controlled. The sewage treatment process itself also consumes a lot of energy and resources, including electricity, chemicals, etc. The traditional toilet treatment method for feces and sewage is not suitable for scenes without sewers, so there are certain limitations. Since there is no sewer, the waste produced by the toilet will continue to accumulate in the feces box. If the feces box is not emptied in time, the toilet will become unusable and a large amount of foul-smelling and irritating gas will be produced, polluting the environment. Summary of the invention

[0038] [Example 1]

[0039] The inventor of this solution found that in the prior art, the traditional toilet treatment method for feces and sewage is not suitable for scenes without sewers, and thus has certain limitations. Since there is no sewer, the sewage generated by the toilet will continue to accumulate in the feces box. If the feces box is not emptied in time, the toilet will become unusable and will also produce a large amount of foul-smelling irritating gas, polluting the environment. The embodiment of the present invention provides the following solution:

[0040] like Figure 1 As shown, an embodiment of the present invention provides a manure incineration system, including an incineration furnace body 1, a catalytic heating device 2 and an exhaust fan 3, wherein a manure heating device 4 is arranged in the incineration furnace body 1. The incineration furnace body 1 is provided with an air inlet and an exhaust port, the exhaust port is provided with an exhaust temperature detector, the input end of the catalytic heating device 2 is connected to the exhaust port, and the output end of the catalytic heating device 2 is connected to the exhaust fan 3 through an exhaust channel.

[0041] It should be noted that after using the toilet, the feces and sewage are burned in the feces and sewage heating container. A single feces and sewage can complete the four steps of sewage heating, liquid evaporation, solid heating, and solid incineration within 15 minutes. The gas discharged from the incineration furnace body 1 is passed into the catalytic heating device 2 through the exhaust fan. The heated catalyst removes the malodorous and irritating gases and is discharged after being purified, so that the gas generated after incineration can be immediately purified, effectively purifying the odor generated by the incineration of feces and sewage, and avoiding environmental pollution.

[0042] In some embodiments, the catalytic heating device 2 includes an electric heating tube and a catalytic temperature detector. It should be noted that the catalytic electric heater heats the catalyst, such as an ammonia catalyst, a VOC catalyst, etc., and the catalytic temperature detector is used to detect the temperature of the catalyst.

[0043] In some embodiments, the manure heating device 4 is an electric heating tube, and the manure heating device 4 is arranged at the bottom of the incinerator body 1, so that the manure is directly heated and incinerated by the electric heating tube.

[0044] In some embodiments, Figure 2 As shown, the exhaust fan 3 is located below one side of the catalytic heating device 2. After the catalytically purified gas is output from one end of the catalytic heating device 2, it is blown upward by the exhaust fan 3 and then discharged, thereby improving the applicable scenarios.

[0045] In some embodiments, Figure 3 As shown, a condenser 5 is provided between the exhaust fan 3 and the catalytic heating device 2. The gas purified by the catalytic heating device 2 is cooled by the condenser and then discharged, thereby preventing fire or explosion caused by high temperature and also preventing damage to the exhaust fan.

[0046] In some embodiments, Figure 4 As shown, a heat exchanger 6 is provided between the condenser 5 and the catalytic heating device 2. It should be noted that the heat exchanger 6 inhales ambient air at room temperature to heat the air and transports the air to the incinerator body 1, thereby further incinerating the incinerator body 1 and shortening the incineration time.

[0047] In other embodiments, Figure 5 As shown, the condenser 5 is not provided, and the heat exchanger 6 is used to condense the purified gas after catalysis, and at the same time, inhale the outside room temperature air to heat it and transport it to the incinerator body 1, so as to further incinerate the incinerator body 1, improve the heating efficiency and shorten the incineration time.

[0048] In some embodiments, a sensitizer is provided in the incinerator body 1 to accelerate the incineration of feces and sewage in the incinerator body 1 .

[0049] In some embodiments, Figures 6 to 9As shown, the manure heating device 4 includes a crucible 41, a microwave power supply 42, a magnetron 43 and a waveguide tube 44. The waveguide tube 44 is connected to one side of the incineration furnace body 1 and leads to the crucible 41. The microwave power supply 42, the magnetron 43 and the waveguide tube 44 are connected in sequence, so that microwaves are used to heat and burn the manure in the crucible.

[0050] In other embodiments, Figures 10 to 13 As shown, the manure heating device 4 includes an electric baking tube 45, which is arranged above the crucible 41, so that the crucible 41 is further heated by the electric baking tube 45 on the basis of microwave heating, thereby improving the heating effect.

[0051] [Example 2]

[0052] The embodiment of the present invention also provides a method for incinerating manure waste using the embodiment 1, comprising:

[0053] Step 1: Heat and incinerate the manure and at the same time raise the temperature of the catalyst used for gas purification to a catalytic reaction temperature range.

[0054] In some embodiments, a sensitizer is added to the incinerator body 1, and the excrement is heated and incinerated in the incinerator body 1 by microwave heating, thereby accelerating the incineration of the excrement.

[0055] Step 2: The gas generated by the incineration forms catalytic combustion with the catalyst in the catalytic reaction temperature range;

[0056] Step three, cooling and discharging the gas after catalytic combustion.

[0057] In some embodiments, the gas after catalytic combustion is sequentially introduced into the heat exchanger and the condenser. The heat exchanger draws in ambient air to heat it and delivers it to the incinerator body, thereby further incinerating the incinerator body 1, improving the heating efficiency and shortening the incineration time.

[0058] In a specific implementation, after using the toilet, the feces and sewage fall into the incinerator body 1, and air is sucked into the incinerator body 1 through the air inlet. The catalytic heating device 2 is turned on, and the catalyst temperature is monitored in real time by the catalytic temperature detector installed on the catalyst surface. The electric heating tube and the catalytic temperature detector are jointly controlled to always control the temperature within the set working temperature range.

[0059] Keep the catalytic heating device turned on, turn on the microwave power supply 42, turn on the exhaust fan to the preset manure heating air volume gear, and then turn on the condenser. At this time, the manure will gradually rise from about 37 degrees to the boiling temperature of the liquid. The exhaust fan forms a negative pressure in the cavity, and fresh air enters through the air inlet of the incinerator body 1 and mixes with the odorous irritating gas and a small amount of water vapor. When the catalyst is heated to the working temperature, catalytic combustion is formed. The carbon and hydrogen components in the volatile organic compounds (VOCs) pollutants are converted into carbon dioxide and water, and ammonia is converted into nitrogen and carbon dioxide. After catalytic combustion, purification is completed. After cooling in the condenser, it enters the exhaust fan to complete the discharge of purified gas.

[0060] When the liquid boils, keep the catalytic heating device 2 turned on, keep the microwave power supply 42 turned on, turn on the exhaust fan to the preset liquid evaporation gear, and keep the condenser turned on. The exhaust fan forms a negative pressure in the cavity, and fresh air enters through the air inlet of the incinerator body 1 and mixes with the odorous and irritating gas and a small amount of water vapor. When the catalyst is heated to the working temperature, catalytic combustion is formed. The carbon and hydrogen components in the volatile organic compounds (VOCs) pollutants are converted into carbon dioxide and water, and ammonia is converted into nitrogen and water. After catalytic combustion, purification is completed, and after cooling by the condenser, it enters the exhaust fan to complete the discharge of purified gas. At this stage, due to the high concentration of water vapor, if the system is equipped with a condenser, condensed water will be generated. At this time, the condensed water is colorless, odorless, and non-polluting distilled water, which is directly discharged through the exhaust channel.

[0061] After the liquid is evaporated, it enters the solid heating stage. At this time, there is no liquid in the incinerator body 1. The solid heats up rapidly under the action of microwaves and sensitizers. The excrement can quickly climb from the boiling temperature of the liquid. Keep the catalytic heating device turned on, keep the microwave power supply 42 turned on, and keep the condenser turned on. The exhaust temperature detector is used to determine whether the liquid evaporation is over. If the exhaust temperature detector detects that the exhaust temperature rises rapidly, it means that the liquid evaporation stage has ended, and the exhaust fan is switched to the preset solid heating gear. The exhaust fan forms a negative pressure in the cavity. Fresh air enters through the air inlet of the incinerator body 1 and mixes with odorous irritating gases and a small amount of water vapor. When the catalyst is heated to the working temperature, catalytic combustion is formed. The carbon and hydrogen components in the volatile organic compounds (VOCs) pollutants become carbon dioxide and water, and ammonia becomes nitrogen and water. After catalytic combustion, purification is completed. After cooling by the condenser, it enters the exhaust fan to complete the discharge of purified gas.

[0062] The solid is rapidly heated to the ignition point under the action of microwaves and sensitizers. The exhaust temperature detector is used to determine whether the solid has reached the ignition temperature. If it has ignited, the exhaust fan is switched to the preset solid incineration gear. The condenser is kept on, and the catalytic heating device 2 is turned off for heating. At this time, since the exhaust temperature in the incinerator body 1 is relatively high, the catalyst can maintain the working temperature without electric heating. When the exhaust temperature in the incinerator body 1 reaches the preset stable combustion temperature, the microwave power supply 42 is turned off. At this time, the solid achieves stable combustion without external heating and only ventilation.

[0063] After the solid is incinerated for a period of time, the exhaust temperature in the incinerator body 1 begins to drop. The exhaust temperature is used to determine whether the solid has been completely incinerated. If the exhaust temperature drops to the preset incineration end temperature, the exhaust fan is switched to the preset incineration end gear. At this time, the air volume of the exhaust fan is reduced until the exhaust temperature drops to the preset complete ashing temperature. It is determined that the incineration is completed and the solid is completely ashed. At this time, the condenser and the exhaust fan are still closed after a delay of a period of time.

[0064] In summary, embodiments 1-2 of the present invention provide a manure incineration system and a process method thereof, wherein an electric heater and a temperature sensor are simultaneously arranged in the catalytic device, so that the preheating control of the working range of the catalytic device can be completed in advance. Then, the temperature of the manure is rapidly increased by sensitizer and microwave heating, and the manure is incinerated. The gas generated after the incineration enters the preheated catalytic device and is immediately purified, thereby incinerating the manure without water resources, and effectively purifying the odor generated by the incineration of manure, thereby avoiding environmental pollution.
