TECHNICAL FIELD
[0001] The present application relates to the field of waste incineration disposal, in particular to a waste pool ventilation and deodorization system and a regulation method thereof. BACKGROUND
[0002] Waste incineration disposal is an important part of improving the ecological environment quality of towns and improving the level of urban public services, and is also the mainstream technology of waste resource and harmlessness disposal in countries at present. After years of development, waste incineration disposal technology in China has gradually developed from being able to burn and burn well to clean burning. For clean burning of waste, in addition to how to prevent and control atmospheric pollution and ash pollution generated in the process of waste incineration, it is also necessary to focus on how to prevent and control the diffusion of episodic odor pollutants brought about by waste incineration disposal, which is also one of the fundamental reasons for the "avoidance of neighbors" problem of waste incineration plants. Although the current waste incineration plants are equipped with odor pollutant removal systems, there are widespread problems such as poor deodorization effect, high cost, and poor safety performance in actual operation. Therefore, the prevention and control of episodic odor pollutants in the process of waste incineration disposal is still one of the key problems that need to be solved in the process of clean waste incineration disposal.
[0003] The waste pool, as the main source of odor gas, is a key factor in the control of episodic odor pollution in waste incineration plants, and reasonable ventilation design is a necessary means to prevent odor pollutants from diffusing into the environment. The collected odor gas from the waste pool can be treated by the primary air intake of the boiler, which can effectively remove the odor gas through incineration while ensuring the negative pressure of the waste pool and preventing the diffusion of odor gas. At the same time, in order to prevent the leakage of odor gas from the waste pool and the explosion caused by the over-standard flammable and explosive gas in the waste pool, the waste pool needs to maintain a certain stable negative pressure through effective ventilation design. At this time, reasonable ventilation and deodorization system design, effective waste pool negative pressure control system, prevention of the formation of ventilation stagnation area and odor gas leakage are the key to the design of the waste pool.

[0038] The beneficial effects of the present application are: the garbage raw materials enter the unloading hall from the feeding mechanism and then enter the solid-liquid separation mechanism, which is beneficial to dry-wet separation of the garbage raw materials, the leachate in the garbage raw materials enters the liquid collecting mechanism for treatment, and meanwhile, the air guiding mechanism and the air outlet mechanism can uniformly collect and treat the odor in the whole system, which is beneficial to reducing the odor generated in the subsequent garbage incineration process.
[0039] Preferably, as shown in Figure 2 The solid-liquid separation mechanism 1 further comprises a plurality of skylights 101, a plurality of garbage discharge outlets 104, a plurality of heaters 106 and a pressure gauge 107. The skylights 101 are arranged at the top end of the garbage pool 108. The garbage discharge outlets 104 are through holes arranged on the side wall of the garbage pool 108. The heaters 106 are arranged on the inner wall at the bottom end of the garbage pool 108. The pressure gauge 107 is arranged on the inner side wall of the garbage pool 108.
[0040] The beneficial effects of the above preferred scheme are: the solid-liquid separation mechanism is beneficial to dry-wet separation of the garbage raw materials and preliminary reduction of the odor in the garbage raw materials. The skylights are beneficial to discharging the odor in the garbage pool when the garbage pool cannot timely discharge the odor or the odor discharge port is blocked or damaged, avoiding gas explosion. The odor discharge port is beneficial to discharging the odor in the garbage pool to the external incinerator for treatment. The emergency exhaust port is convenient for adjusting the air pressure in the garbage pool when the garbage incinerator is overhauled. The garbage discharge outlet is beneficial to discharging the solid garbage in the garbage pool, which has been separated from the leachate, to the external incinerator for incineration. The negative pressure air blower cooperates with the pressure gauge to be beneficial to adjusting the air pressure in the garbage pool and discharging the odor. The heaters are beneficial to heating the garbage raw materials, thereby realizing solid-liquid separation.
[0041] Preferably, as shown in Figure 2 and Figure 3 The liquid collecting mechanism 2 comprises a leachate channel 21, an odor detection probe 22, a leachate pool 23, a leachate drainage port 24, an overhauling channel 25, a safety guardrail 26 and a liquid collecting chamber 27. The liquid collecting chamber 27 is a closed space connected with the side wall of the garbage pool 108. The leachate channel 21 is a groove-shaped structure arranged on the inner wall at the bottom end of the liquid collecting chamber 27 and close to the end of the solid-liquid separation mechanism 1. The odor detection probe 22 is arranged on the inner side wall of the liquid collecting chamber 27. The leachate pool 23 is a shell structure with an open top end. The leachate pool 23 and the leachate channel 21 are connected through. The leachate drainage port 24 is a through hole arranged on the side wall of the leachate pool 23. The overhauling channel 25 is arranged on the inner wall at the bottom end of the liquid collecting chamber 27 and away from the end of the leachate channel 21. The safety guardrail 26 is arranged between the leachate channel 21 and the overhauling channel 25.
[0042] The beneficial effects of the above preferred scheme are that the liquid collecting mechanism is conducive to collecting the leachate separated from the solid-liquid separation mechanism. Among them, the leachate channel cooperates with the leachate pool and the leachate drainage port to facilitate the collection and drainage treatment of leachate with odor, reducing the odor generated by subsequent garbage incineration; the odor detection probe cooperates with the maintenance channel and the safety guardrail to facilitate the regular entry of workers into the liquid collecting chamber for maintenance and repair of each component.
[0043] Preferably, as shown in Figure 1 and Figure 2 , the air induction mechanism 4 is a tubular structure, and the bottom end of the air induction mechanism 4 and the top end of the liquid collecting chamber 27 are connected through.
[0044] Preferably, as shown in Figure 1 and Figure 2 , the air outlet mechanism 5 is a hollow columnar structure with openings at the bottom and the side wall, the bottom end of the air outlet mechanism 5 and the top end of the liquid collecting chamber 27 are connected through, and the side wall of the air outlet mechanism 5 and the side wall of the garbage pool 108 are connected through.
[0045] Among them, it needs to be understood that: because the functions of the air induction mechanism 4 and the air outlet mechanism 5 are to send the odor of the leachate in the liquid collecting chamber 27 into the garbage pool 108, and then sent to the external incinerator for treatment, and at the same time, the side walls of the liquid collecting chamber 27 and the garbage pool 108 are connected, therefore, in other embodiments, the air induction mechanism 4 can be a through hole connecting the external atmosphere and the liquid collecting chamber 27, and the air outlet mechanism 5 can be a through hole connecting the liquid collecting chamber 27 and the garbage pool 108.
[0046] The beneficial effects of the above preferred scheme are that the air induction mechanism is conducive to introducing external air into the liquid collecting chamber, and then sending the odor in the liquid collecting chamber into the garbage pool through the air outlet mechanism, and then into the external incinerator for odor treatment.
[0047] Preferably, as shown in Figure 4 , the feeding mechanism 9 includes a first air curtain 91, a second air curtain 92, and a feeding passage 93, the feeding passage 93 is a tubular structure connected through the end of the unloading hall 3 away from the solid-liquid separation mechanism 1, the first air curtain 91 and the second air curtain 92 are plate-shaped structures adapted to the inner circle cross section of the feeding passage 93, and the first air curtain 91 and the second air curtain 92 are arranged at both ends of the feeding passage 93.
[0048] The advantages of adopting the above-mentioned preferred scheme are: the unloading hall, in conjunction with the feeding mechanism, facilitates the entry of external waste materials into the unloading hall via the feeding mechanism, and then into the solid-liquid separation mechanism from the unloading hall. Specifically, the first and second air curtains help prevent the odor emitted from the waste materials within the unloading hall from spreading into the external atmosphere, thus reducing air pollution.
[0049] Preferred, such as Figure 5 As shown, a garbage pit ventilation and deodorization system also includes a garbage workshop 10, which is an enclosed space. The solid-liquid separation mechanism 1, the liquid collection mechanism 2, the unloading hall 3, the exhaust fan mechanism 4, the exhaust fan mechanism 5, the staircase 6, the unloading port 7, the leachate outlet 8, and the feeding mechanism 9 are all located in the garbage workshop 10.
[0050] The beneficial effects of adopting the above-mentioned preferred scheme are: the waste deodorization workshop is the main place for waste deodorization and feeding, and the incineration workshop is the main place for odor treatment and waste incineration. Separating deodorization and odor treatment is conducive to modular treatment of odor and improves the efficiency of waste odor treatment.
[0051] Preferred, such as Figure 5 As shown, a garbage pit ventilation and deodorization system further includes a vestibule area 12 and an air extraction pump 13. The vestibule area 12 is an enclosed space located between the garbage workshop 10 and the incineration workshop 11. Both ends of the vestibule area 12 are connected to the garbage workshop 10 and the incineration workshop 11 through each other. The air extraction pump 13 is located on the side wall of the vestibule area 12.
[0052] The advantages of adopting the above-mentioned preferred scheme are: the vestibule area provides the necessary passage for the connection between the waste workshop and the incineration workshop, facilitates the daily work of the staff, and at the same time, the gas in the waste workshop and the incineration workshop is continuously connected to the outside through the air pump, which helps to prevent the odor treated in the incineration workshop from flowing back to the waste workshop.
[0053] It is important to understand that in the odor control system for a garbage pit described in this invention, the flow of odor is as follows: When a garbage truck transports garbage materials through the first air curtain 91, the feeding channel 93, and the second air curtain 92 into the unloading hall 3, the garbage materials enter the garbage pit 108 from the unloading port 7. Under the heating action of the heater 106, leachate containing odor will flow from the leachate outlet 8 into the leachate channel 21. The leachate flows along the leachate channel 21 into the leachate pool 23 for storage, and finally is diverted to the outside for treatment through the leachate inlet 24. When the odor concentration in the collection chamber 27 is too high, external air is introduced into the collection chamber 27 through the exhaust fan 4. The external air carries the odor and enters the garbage pit 108 from the exhaust fan 5. Finally, all the odor enters the odor and garbage treatment equipment located in the incineration workshop 11 from the odor emission port 102 for treatment.
[0054] like Figure 6 As shown, a method for controlling a ventilation and deodorization system for a garbage dump includes the following steps:
[0055] S1: Adjust the negative pressure in the garbage pit 108 according to the air volume of the negative pressure fan 105 and the opening and number of the unloading port 7, so that the negative pressure in the garbage pit 108 is within the standard range.
[0056] S2: Confirm whether the quantity of unloading port 7 has increased or decreased;
[0057] S3: Confirm whether the liquid collection mechanism 2 needs maintenance;
[0058] S4: Confirm whether incineration workshop 11 needs maintenance.
[0059] Preferred, such as Figure 6 As shown, in step S2, if the number of unloading ports 7 increases or decreases, it is confirmed whether the negative pressure in the waste pool 108 is within the standard range. If the negative pressure in the waste pool 108 is not within the standard range, the operation of step S1 is repeated. If the number of unloading ports 7 does not increase or decrease, the process proceeds to step S3. If the liquid collection mechanism 2 needs maintenance, the induced draft mechanism 4 and the exhaust mechanism 5 are adjusted to ensure that the negative pressure in the liquid collection mechanism 2 is within the standard range. If the liquid collection mechanism 2 does not need maintenance, the process proceeds to step S4. If the incineration workshop 11 needs maintenance, the odor emission port 102 is closed, the emergency exhaust port 103 is opened, and the negative pressure in the waste pool 108 is confirmed again to be within the standard range. If the negative pressure in the waste pool 108 is not within the standard range, the operation of step S1 is repeated.
[0060] It is important to understand that the negative pressure in the waste pool 108 and the liquid collection mechanism 2 is generally between -60Pa and -10Pa within the standard range.
[0061] In step S1, observe the value of pressure gauge 107. If the value of pressure gauge 107 is between -60Pa and -10Pa, proceed to step S2. If the value of pressure gauge 107 is greater than -10Pa, reduce the air volume of negative pressure induced draft fan 105. If the value of pressure gauge 107 is between -60Pa and -10Pa after reducing the air volume of negative pressure induced draft fan 105, proceed to step S2. If the value of pressure gauge 107 is still greater than -10Pa, reduce the opening of discharge port 7. If the value of pressure gauge 107 is between -60Pa and -10Pa after reducing the opening of discharge port 7, proceed to step S2. If the value of pressure gauge 107 is still greater than -10Pa, reduce the number of discharge ports 7 until the negative pressure in garbage pit 108 is between -60Pa and -10Pa. If the value of pressure gauge 107 is less than -60 Pa, the air volume of negative pressure induced draft fan 105 is increased. If the value of pressure gauge 107 is between -60 Pa and -10 Pa after increasing the air volume of negative pressure induced draft fan 105, then proceed to step S2. If the value of pressure gauge 107 is still less than -60 Pa, the opening of discharge port 7 is increased. If the value of pressure gauge 107 is between -60 Pa and -10 Pa after increasing the opening of discharge port 7, then proceed to step S2. If the value of pressure gauge 107 is still less than -60 Pa, then the number of discharge ports 7 is increased until the negative pressure in garbage pit 108 is between -60 Pa and -10 Pa.
[0062] The beneficial effects of this invention are: by adjusting the air pressure in the waste pit and the liquid collection mechanism to the standard range of negative pressure, it is beneficial to utilize atmospheric pressure to prevent the odor in the waste pit and the liquid collection mechanism from spreading to the outside due to the random movement of gas molecules, thereby reducing the "neighborhood avoidance" phenomenon of waste incineration plants.
