Description

Technical Field

[0001] The present invention relates to the technical field of harmless disposal equipment, and in particular to a device capable of verifying the harmless disposal of animal corpse remains at high temperature and high pressure. Background Art

[0002] At present, there are several treatment processes for harmless disposal of dead animals, including incineration, chemical treatment, landfill, and fermentation. The incineration method is thorough but consumes a lot of energy and cannot generate economic benefits; the landfill method requires a large amount of land resources and is prone to pollute groundwater. The fermentation method takes too long and cannot be used to treat a large number of dead animals. High-temperature chemical treatment refers to the process of digesting the bodies of dead animals into sterile solutions and dry bone residues under the action of high temperature and pressure in a closed high-pressure container by passing high-temperature saturated steam into the container interlayer or container, while killing all pathogenic microorganisms. The chemical treatment method has the advantages of simple operation, strong processing capacity, good sterilization effect, and short processing cycle. The main equipment for implementing the chemical treatment method is the sterilization chamber. In the past, chemical treatment operations had to be carried out based on experience, that is, different parameters such as temperature and time had to be controlled based on experience with different types of animal carcasses. The sterilization chamber could not directly sample and verify the sterilization effect of the waste and its waste gas and wastewater in the sterilization chamber. The entire operation had to be carried out based on experience, which made it impossible to accurately control the time and effect of chemical treatment, and it was impossible to accurately control the energy consumption of the sterilization chamber, so improvements were needed.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Example: A verifiable high-temperature and high-pressure animal carcass harmless treatment device.

[0021] Referring to Figure 1 As shown, a verifiable high-temperature and high-pressure animal carcass harmless treatment device includes a sterilization chamber 1 and a control system. A hatch door 29 is provided at the top of the sterilization chamber 1. An automatic locking mechanism driven by compressed air is installed on the hatch door 29. During actual operation, the animal carcass can be sent into the sterilization chamber 1 through the hatch door 29, and then the automatic locking mechanism driven by compressed air locks the hatch door 29 to prevent air leakage from the hatch door 29. A leaving-point thermometer 18 extending into the interior of the sterilization chamber is installed at the top of the sterilization chamber 1, which can accurately measure the temperature inside the sterilization chamber 1 in real time. A biological filter 5 is installed at the top of the sterilization chamber 1. An exhaust pipe 6 is installed at the top of the biological filter 5, and the end of the exhaust pipe 6 is connected to an exhaust gas treatment device. During actual operation, during the heating process of the sterilization chamber 1, the air inside the chamber is discharged through the biological filter 5 and is not closed until all the steam replaces the air. The air after passing through the biological filter 5 is released to the exhaust gas treatment device. During the sterilization process, the biological filter 5 is sterilized as an integral part of the chamber.

[0022] An exhaust gas collection module is installed on the exhaust pipe 6. The exhaust gas collection module includes a three-way pneumatic angle valve 7 installed on the exhaust pipe 6. An exhaust gas collection main pipe 8 is installed at the rear end of the three-way pneumatic angle valve 7. A three-way valve 9 is installed at the end of the exhaust gas collection main pipe 8. Symmetrically arranged first exhaust gas collection branch pipes 30 and second exhaust gas collection branch pipes 31 are installed at the left and right ends of the three-way valve 9. A first exhaust gas collection automatic valve 10 is installed on the first exhaust gas collection branch pipe 30. A first exhaust gas collection manual valve 11 is installed behind the first exhaust gas collection automatic valve 10. A first exhaust gas collection bottle 13 is detachably installed at the end of the first exhaust gas collection branch pipe 30. A first pressure gauge 12 is installed at the connection between the first exhaust gas collection bottle 13 and the first exhaust gas collection branch pipe 30. A second exhaust gas collection automatic valve 14 is installed on the second exhaust gas collection branch pipe 31. A second exhaust gas collection manual valve 15 is installed behind the second exhaust gas collection automatic valve 14. A second exhaust gas collection bottle 17 is detachably installed at the end of the second exhaust gas collection branch pipe 31. A second pressure gauge 16 is installed at the connection between the second exhaust gas collection bottle 17 and the second exhaust gas collection branch pipe 31.

[0023] In the above solution, the exhaust gas collection module is mainly used to collect the exhaust gas in the sterilization chamber 1. The exhaust gas collection has two modes: automatic sampling and manual sampling. When the automatic sampling mode is adopted, the first exhaust gas collection manual valve 11 and the second exhaust gas collection manual valve 15 are in the normally open state, and the three-way pneumatic angle valve 7, the three-way valve 9, the first exhaust gas collection automatic valve 10, and the second exhaust gas collection automatic valve 14 are in the closed state. When automatic sampling is required, the control system controls the opening of the three-way pneumatic angle valve 7, opens the gas path between the three-way valve 9 and the first exhaust gas collection branch pipe 30, and slowly opens the first exhaust gas collection automatic valve 10. When the first pressure gauge 12 detects that the pressure is close to the internal and external balance, the first exhaust gas collection automatic valve 10 is closed, the gas path between the three-way valve 9 and the second exhaust gas collection branch pipe 31 is opened, and the second exhaust gas collection automatic valve 14 is slowly opened. When the second pressure gauge 16 detects that the pressure is close to the internal and external balance, the second exhaust gas collection automatic valve 14 is closed, and finally the three-way pneumatic angle valve 7 is closed to complete the two-stage automatic sampling of the exhaust gas. The second exhaust gas collection bottle 17 is taken down and sent to a qualified department to detect the sterilization effect and tissue content of the sample. Since the first exhaust gas collection bottle 13 contains a small amount of air and impurities, it cannot be used for inspection, otherwise it will affect the accuracy of the detection. When the manual sampling mode is adopted, the first exhaust gas collection automatic valve 10 and the second exhaust gas collection automatic valve 14 are in the normally open state, and the three-way pneumatic angle valve 7, the three-way valve 9, the first exhaust gas collection manual valve 11, and the second exhaust gas collection manual valve 15 are in the closed state. When manual sampling of the exhaust gas is required, the operator first slowly opens the first exhaust gas collection manual valve 11. After the control system detects the opening of the first exhaust gas collection manual valve 11, the three-way pneumatic angle valve 7 is opened, and the gas path between the three-way valve 9 and the first exhaust gas collection branch pipe 30 is opened. When the first pressure gauge 12 detects that the pressure is close to the internal and external balance, the first exhaust gas collection manual valve 11 is manually closed. After the control system detects the closing of the first exhaust gas collection manual valve 11, the gas path between the three-way valve 9 and the second exhaust gas collection branch pipe 31 is opened, and the operator slowly opens the second exhaust gas collection manual valve 15. When the second pressure gauge detects that the pressure is close to the internal and external balance, the operator closes the second exhaust gas collection manual valve 15, and the system controls the three-way pneumatic angle valve 7 to close, and then the second exhaust gas collection bottle 17 is taken down and sent to a qualified department to detect the sterilization effect and tissue content of the sample.

[0024] Through the innovative design of the exhaust gas sampling module, the present invention can not only use the automatic mode, but also implement the manual sampling mode, and realizes the two-stage sampling of the exhaust gas. Since the exhaust gas collected in the first exhaust gas collection bottle 13 contains a small amount of ambient air and impurities, it needs to be discarded, otherwise it will affect the result of the exhaust gas detection. The complete exhaust gas collected in the second exhaust gas collection bottle 17 is used for inspection, thereby improving the accuracy of the exhaust gas inspection.

[0025] A drain pipe 23 is installed at the bottom of the sterilization chamber 1, and the end of the drain pipe 23 is connected to a wastewater treatment device. A wastewater collection pipe 24 is installed on the drain pipe 23, a wastewater collection automatic valve 25 is installed on the wastewater collection pipe 24, a wastewater collection manual valve 26 is installed behind the wastewater collection automatic valve 25, and a wastewater collection bottle 27 is detachably installed at the end of the wastewater collection pipe 24. During actual operation, wastewater sampling also includes an automatic sampling mode and a manual sampling mode. When using the automatic sampling mode, the wastewater collection manual valve 26 is in the normally open state, and the control system can achieve automatic wastewater sampling only by controlling the opening and closing of the wastewater collection automatic valve 25. When using the manual sampling mode, the wastewater collection automatic valve 25 is in the normally open state, and the operator can achieve manual wastewater sampling only by controlling the opening and closing of the wastewater collection manual valve 26.

A waste collection automatic valve 20 is installed on the waste collection pipe 19, a waste collection manual valve 21 is installed behind the waste collection automatic valve 20, and a waste collection bottle 22 is detachably installed at the end of the waste collection pipe 19. In the present invention, the detachable installation is all thread installation or snap installation. During actual operation, waste sampling also includes an automatic sampling mode and a manual sampling mode. When using the automatic sampling mode, the waste collection manual valve 21 is in the normally open state, and the control system can achieve automatic waste sampling only by controlling the opening and closing of the waste collection automatic valve 20. When using the manual sampling mode, the waste collection automatic valve 20 is in the normally open state, and the operator can achieve manual waste sampling only by controlling the opening and closing of the waste collection manual valve 21.

[0027] A crushing knife 2 is installed in the sterilization chamber 1. The crushing knife 2 is connected to a driving motor through a driven wheel 3 installed at the bottom of the crushing knife 2. The installation height of the crushing knife 2 is basically the same as the installation height of the waste collection pipe 19. During actual operation, while the sterilization chamber 1 is heating up, the driving motor can be controlled to drive the crushing knife 2 to crush the animal carcass waste in the sterilization chamber 1, so that the waste is evenly heated, and centrifugal driving force can be provided for waste sampling.

[0028] The steam injection pipe 4 is installed at the bottom of the sterilization chamber 1. A steam injection solenoid valve 28 is installed on the steam injection pipe 4. During actual operation, the steam injection solenoid valve 28 can be used to control the steam injection pipe 4 to inject high-temperature and high-pressure steam into the sterilization chamber 1. A heating device is installed in the sterilization chamber 1. During actual operation, the sterilization chamber 1 is electrically heated, or external steam can be connected through the steam injection pipe 4 to operate with saturated steam as the fungicide, with a temperature range of up to 134°C to 137°C and a pressure of up to 2.5 MPa (absolute pressure of 3.5 MPa). An indication and control module is provided outside the sterilization chamber 1. The main state parameters of the operating mode, temperature and pressure, are controlled and displayed on the indication and control module, and important information can be printed.

[0029] The control system is electrically connected to the three-way pneumatic angle valve 7, the three-way valve 9, the first waste gas collection automatic valve 10, the second waste gas collection automatic valve 14, the first pressure gauge 12, the second pressure gauge 16, the dial thermometer 18, the waste water collection automatic valve 25, the waste collection automatic valve 20, the drive motor, the steam injection solenoid valve 28, the heating device and the indication and control module respectively to achieve automatic control of the equipment operation process.

[0030] In the present invention, the operating modes of the verifiable high-temperature and high-pressure animal carcass and residue harmless treatment equipment include an automatic sampling mode and a manual sampling mode:

[0031] Automatic sampling mode: Before the automatic sampling mode is turned on, the control system first checks that the first waste gas collection manual valve 11, the second waste gas collection manual valve 15, the waste water collection manual valve 26, and the waste collection manual valve 21 are in the open state to ensure that the system can perform automatic sampling. At this time, the three-way pneumatic angle valve 7, the three-way valve 9, the first waste gas collection automatic valve 10, the second waste gas collection automatic valve 14, the waste water collection automatic valve 25, and the waste collection automatic valve 20 are in the closed state; when automatic waste gas sampling is required, the control system controls the three-way pneumatic angle valve 7 to open, opens the gas path between the three-way valve 9 and the first waste gas collection branch pipe 30, and slowly opens the first waste gas collection automatic valve 10. When the first pressure gauge 12 detects that the pressure is close to internal and external balance, the first waste gas collection automatic valve 10 is closed, the gas path between the three-way valve 9 and the second waste gas collection branch pipe 31 is opened, and the second waste gas collection automatic valve 14 is slowly opened. When the second pressure gauge 16 detects that the pressure is close to internal and external balance, the second waste gas collection automatic valve 14 is closed, and finally the three-way pneumatic angle valve 7 is closed to complete the secondary automatic sampling of the waste gas. The second waste gas collection bottle 17 is taken off and sent to a qualified department to detect the sterilization effect and tissue content of the sample. The first waste gas collection bottle 13 is discarded after being taken off because it contains a small amount of air and impurities; when automatic waste sampling is required, the control system controls the waste collection automatic valve 20 to open, and then drives the motor to drive the crushing knife 2 to rotate at a high speed. The centrifugal force generated during the rotation of the crushing knife 2 is used to convey the crushed waste into the waste collection bottle 22, and then the waste collection automatic valve 20 is closed; when automatic waste water sampling is required, the control system controls the waste water collection automatic valve 25 to open. When the water level in the waste water collection bottle 27 reaches the sampling water level, the waste water collection automatic valve 25 is automatically closed.

When manual waste gas sampling is required, the operator first slowly opens the first waste gas collection manual valve 11. After the control system detects that the first waste gas collection manual valve 11 is opened, the three-way pneumatic angle valve 7 automatically opens, and automatically opens the gas path between the three-way valve 9 and the first waste gas collection branch pipe 30. When the first pressure gauge 12 detects that the pressure is close to internal and external balance, the first waste gas collection manual valve 11 is manually closed. After the control system detects that the first waste gas collection manual valve 11 is closed, it automatically switches to open the gas path between the three-way valve 9 and the second waste gas collection branch pipe 31. The operator slowly opens the second waste gas collection manual valve 15. When the second pressure gauge 16 detects that the pressure is close to internal and external balance, the operator manually closes the second waste gas collection manual valve 15, and the system controls the three-way pneumatic angle valve 7 to automatically close; when manual waste sampling is required, the control system detects that the waste collection manual valve 21 is opened, and the control system automatically turns on the drive motor to drive the crushing knife 2 to rotate at a high speed. The centrifugal force generated during the rotation of the crushing knife 2 is used to convey the crushed waste into the waste collection bottle 22, and then the waste collection manual valve 21 is manually closed; when manual waste water sampling is required, the operator manually opens the waste water collection manual valve 26. When the water level in the waste water collection bottle 27 reaches the sampling water level, the waste water collection manual valve 26 is manually closed.
