[0002] Municipal sludge is the sediment produced in the process of urban sewage treatment. It is a mixture of suspended solids, microorganisms, organic matter, inorganic matter, heavy metals, etc. in sewage. With the continuous improvement of industry and human living standards, the amount of sludge will continue to increase. However, in order to solve the adverse factors brought by urban sludge and realize the utilization rate of sludge, urban sludge treatment plants will first use deep dehydration and incineration treatment to treat it, and then crush, screen and grade the generated ash to screen out ash particles of the required size for use.

[0003] In the existing technology, the existing urban sludge deep dehydration and incineration treatment system can solve the problems caused by urban sludge in actual use, and can also assist power generation equipment in power generation operations to generate electricity resources. At the same time, it can also crush the generated ash and sieve out ash particles of the required size for use. However, it does not have the function of killing pathogens in urban sludge before incineration. That is, during the process of filtration, reception, storage and transportation of urban sludge, pathogens will be dispersed in the air. If the staff works in this environment for a long time, they will develop diseases due to the pathogens, thereby affecting their health, which not only reduces the use effect of the urban sludge deep dehydration and incineration treatment system, but also reduces the use efficiency of the urban sludge deep dehydration and incineration treatment system.

Multiple groups of shells 211 are fixed on the outer surface of the rotating rod 210. One side of the placement rack 201 A concave block 212 with a hole is fixed, a motor 213 and a fan 214 are installed on the top of the concave block 212 with a hole, a controller 215 is installed on the front surface of the concave block 212 with a hole, a generator 216 and a gas storage tank 217 are placed at the bottom of the inner wall of the concave block 212 with a hole, a second electric valve 218 is installed at the gas outlet end of the gas storage tank 217, a one-way valve 219 is installed at the gas inlet end of the gas storage tank 217, a sensor 220 is installed at the gas outlet end of the second electric valve 218, an inlet pipe 221 is installed at both the gas inlet end and the gas outlet end of the generator 216, an outlet pipe 222 is installed at the gas outlet end of the fan 214, and the rotating rod 210 is movable. The housing 211 is sleeved inside the cylinder 204, and the number of each housing 211 is three. The bottom of the concave block 212 with holes and the bottom of the placement rack 201 are on the same horizontal plane. The output end of the motor 213 is installed with one end of the rotating rod 210. The inlet end of one of the air inlet pipes 221 is connected to the outlet end of the sensor 220, and the outlet end of the other air inlet pipe 221 is movably sleeved inside the through hole on the top of the inner wall of the concave block 212 with holes. The outlet end of the air inlet pipe 221 is connected to the inlet end of the fan 214, and the outlet end of the air outlet pipe 222 is connected to the inlet end of one of the first electric valves 206. The three first electric valves 206 are connected to each other. The movable valve 206, the motor 213, the fan 214, the second electric valve 218, the generator 216 and the sensor 220 are all electrically connected to the controller 215. Each cylinder cover 203 is squeezed and fixed between the inside of each fixed seat 208 and the inside of each auxiliary seat 209. Each shell 211 is located inside the cylinder 204. A plurality of arc frames 202 are fixed inside the placement rack 201. The inner wall arc surfaces of the plurality of arc frames 202 are in contact with the outer wall of the cylinder 204. The feed end of the first electric valve 206 in the middle is installed with the first feed pipe 207. The controller 215 is electrically connected to the control box 106.

[0041] In this embodiment, when the municipal sludge is transported to the interior of the first feed pipe 207, the controller 215 is used to open the middle first electric valve 206. At this time, the municipal sludge transported to the interior of the first feed pipe 207 will be directly transported to the interior of the space composed of the two cylinder covers 203 and the cylinder body 204 under the cooperation of the opened middle first electric valve 206 and the corresponding circular tube 205. When the interior of the space is injected with an appropriate amount of preliminarily treated municipal sludge, the above-mentioned operation steps are stopped, and then the controller 215 is used to close the opened middle first electric valve 206, and then the controller 215 is used to start the generator 216 and the fan 214, and the second electric valve 218 and one of the first electric valves 214 are opened. 06 and flow sensor 220, at this time, the oxygen in the gas storage tank 217 will be directly transported to the interior of the generator 216 through the cooperation of the opened second electric valve 218, the flow sensor 220 and the corresponding air inlet pipe 221. When the oxygen enters the interior of the generator 216, the activated generator 216 will convert the oxygen into ozone.

At the same time, the controller 215 also compares the flow rate value received each time with the flow rate threshold value set in advance by the controller 215. When the flow rate value received by the controller 215 is lower than the flow rate threshold value set in advance by the controller 215, the controller 215 will not close the second electric valve 218, the generator 216, the fan 214 and one of the first electric valves 206. On the contrary, the controller 215 will first close the second electric valve 218, then close the generator 216, then close the fan 214, and then close one of the first electric valves 206. Then, the controller 215 will start the motor 213. At this time, the started motor 213 will cooperate with the sealing bearing and the rotating rod 210. All the shells 211 are driven to rotate inside the space formed by the two cylinder covers 203 and the cylinder body 204. At this time, all the rotating shells 211 will stir the urban sludge inside the space (the space formed by the two cylinder covers 203 and the cylinder body 204) together, so that the urban sludge is fully in contact with the ozone gas, that is, the cell membrane and internal structure of microorganisms such as bacteria and viruses in the urban sludge are oxidized by the ozone gas to make them inactive, thereby killing pathogens such as bacteria, viruses, and fungi. When the urban sludge has completed the pathogen killing operation, the controller 215 is first used to open another first electric valve 206. At this time, the disinfected urban sludge will directly cooperate with the opened other first electric valve 206 and the corresponding round tube 205.The sewage is guided out of the space formed by the two cylinder covers 203 and the cylinder body 204. When there is no municipal sludge discharged from the discharge end of the opened other first electric valve 206, the motor 213 and the other first electric valve 206 are directly closed by the controller 215.

[0042] Embodiment 2: According to Figure 1 , Figure 4-Figure 6 and Figure 9-14 As shown, the processing mechanism 1 includes a cement platform 101, the bottom of the placement rack 201 is in contact with the top of the cement platform 101, an ultra-high pressure laminated filter press 102 is placed on the top of the cement platform 101, a low-temperature belt dryer 103 is placed on the top of the cement platform 101, a sludge incinerator 104 is placed on the top of the cement platform 101, an ash grading processor 105 is placed on the top of the cement platform 101, and a control box 106 is placed on the top of the cement platform 101. The ultra-high pressure laminated filter press 102, the low-temperature belt dryer 103, the sludge incinerator 104 and the ash grading processor 105 are all electrically connected to the control box 106, and the controller 215 is electrically connected to the control box 106.

[0043] In this embodiment, when it is necessary to perform filter pressing operation on the disinfected urban sludge, the prepared waste gas treatment equipment (the treatment principle corresponds to Fig.11 ) and wastewater treatment equipment (treatment principle corresponds to Fig.10 ) are connected to the ultra-high pressure laminate filter press equipment, and then the prepared wastewater treatment equipment (treatment principle corresponds to Fig.10 ) is also connected to the low-temperature belt dryer 103, and then the waste gas treatment equipment (treatment principle corresponds to Fig.11 ) is also connected to the low-temperature belt dryer 103, and the heat in the exhaust gas discharged by the low-temperature belt dryer 103 is recovered by using the prepared heat exchanger and applied to the sludge incinerator 104 (the waste heat recovery and the use principle of the sludge incinerator 104 correspond to Fig.12 ), and then prepare the flue gas treatment equipment (treatment principle corresponds to Fig.13) is connected to the sludge incinerator. When everything is ready, the disinfected urban sludge is first placed on the ultra-high pressure laminated filter press 102, and then the control box 106, the ultra-high pressure laminated filter press 102 and the filter press conditioner are used to dehydrate the urban sludge. Then the waste gas generated by the urban sludge is treated by the waste gas treatment equipment, and the waste water generated is also treated by the waste water treatment equipment. Then the mud cake is received by the designated equipment and place, and the received sludge is stored again. When the stored mud cake needs to be dried again, the mud cake is first transported from the storage place to the place where the sludge can be dried, and then the low-temperature belt dryer 103 and the control box 106 are used to dry the sludge. At this time, the waste water generated is treated by the waste water treatment equipment, and the waste gas generated is also treated by the waste gas treatment equipment. Then the dried sludge is placed in the sludge incinerator 104, and then the control box 1 is used to dry the sludge. 06. The sludge incinerator 104 cooperates with the prepared power generation equipment to perform power generation operations. At this time, the flue gas generated by the sludge incineration can be treated by the flue gas treatment equipment. When the ash generated in the above steps needs to be crushed, screened and graded, the ash is directly collected around the ash grading machine 105. Then, the ash placed in the ash grading machine 105 can be crushed by the cooperation of the ash grading machine 105 and the control box 106. Then, ash particles of the required size can be obtained by screening. The deep dehydration and incineration of the sludge can effectively reduce the thermal drying of the sludge. At the same time, the sludge adopts the ultra-high pressure laminated filter pressing method under the physical state of room temperature, which can make the water filtered out without the thermal energy loss of latent heat of vaporization, that is, the current sludge drying technology before incineration is not mature. The pure drying and water removal technology allows the water in the sludge to be removed at a high temperature, increasing the thermal energy loss of latent heat of vaporization, reducing the calorific value of the sludge and reducing the subsequent power generation efficiency.

[0046] The effect and working principle of the whole mechanism are as follows: when it is necessary to process the urban sludge, the discharge end of the discharge pipe 309 is first connected to the feed end of the first feed pipe 207, and then the control box 106 is connected to the external power supply through a cable, and then the discharge ends of the two conveying pipes conveying the urban sludge (liquid sludge) are respectively aligned with the two circular holes on the double-hole plate 304, and then the discharge ends of the two conveying pipes are connected to the double-hole plate 304, and then the power distribution unit inside the control box 106 is used to power the controller 215, and then the controller 215 is turned on, and the flow rate threshold (the total amount of gas passing through it) and the basic usage procedures are set, and finally the one-way valve 219 is used. In cooperation, an appropriate amount of oxygen is injected into the interior of the gas storage tank 217. When everything is ready, the urban sludge conveying pipe is first used to convey the urban sludge into the space composed of the double-hole plate 304, the V-shaped filter plate 303 and the placement shell 301. When the urban sludge is conveyed into the space, under the action of the V-shaped filter plate 303, the larger objects (various larger garbage) mixed in the urban sludge can be filtered out, and then the filtered urban sludge will flow directly to the surface of the inclined plate 307. At this time, the controller 215 is used to start the plunger pump 302. At this time, the started plunger pump 302 will absorb the urban sludge reaching the surface of the inclined plate 307 under the cooperation of the second feed pipe 306 and the connecting pipe 308, and then convey it to the inside of the discharge pipe 309 , and then transported to the inside of the first feeding pipe 207. When the urban sludge is transported to the inside of the first feeding pipe 207, the controller 215 is used to open the middle first electric valve 206. At this time, the urban sludge transported to the inside of the first feeding pipe 207 will be directly transported to the inside of the space composed of the two cylinder covers 203 and the cylinder body 204 under the cooperation of the opened middle first electric valve 206 and the corresponding round tube 205. When the space is injected with an appropriate amount of preliminarily treated urban sludge, the above-mentioned operation steps are stopped at this time, and then the controller 215 is used to close the opened middle first electric valve 206, and then the controller 215 is used to start the generator 216 and the fan 214, and the second electric valve 21 is opened. 8. One of the first electric valves 206 and the flow sensor 220. At this time, the oxygen in the gas storage tank 217 will be directly transported to the inside of the generator 216 through the cooperation of the opened second electric valve 218, the flow sensor 220 and the corresponding air inlet pipe 221. When the oxygen enters the inside of the generator 216, the activated generator 216 will convert the oxygen into ozone. The subsequently generated ozone will be transported to the inside of the space composed of the two cylinder covers 203 and the cylinder body 204 under the cooperation of the activated fan 214, the corresponding air inlet pipe 221, the air outlet pipe 222, the opened one of the first electric valves 206 and the corresponding round tube 205. At the same time, the flow sensor 220 will also monitor the amount of oxygen passing through it at all times.The values ​​obtained from each monitoring are transmitted to the controller 215 in the form of electrical signals. At the same time, the controller 215 will also compare the flow value received each time with the flow threshold value set in advance by the controller 215. When the flow value received by the controller 215 is lower than the flow threshold value set in advance by the controller 215, the controller 215 will not close the second electric valve 218, the generator 216, the fan 214 and one of the first electric valves 206. On the contrary, the controller 215 will first close the second electric valve 218, then close the generator 216, then close the fan 214, and then close one of the first electric valves 206. Then, the controller 215 will start the motor 213 again. At this time, the started motor 213 will drive all the shells 211 to rotate inside the space composed of the two cylinder covers 203 and the cylinder body 204 with the cooperation of the sealed bearing and the rotating rod 210. At this time, all the rotating shells 211 will stir the space (composed of the two cylinder covers 203 and the cylinder body 204) together. The municipal sludge inside the space formed by the two cylinder covers 203 and the cylinder body 204 is brought into full contact with the ozone gas, that is, the ozone gas is used to oxidize the cell membrane and internal structure of microorganisms such as bacteria and viruses in the municipal sludge, so that they lose their activity, thereby killing pathogens such as bacteria, viruses, and fungi. After the municipal sludge has completed the pathogen killing operation, the controller 215 is used to open the other first electric valve 206. At this time, the disinfected municipal sludge will be directly guided out of the space formed by the two cylinder covers 203 and the cylinder body 204 with the cooperation of the opened other first electric valve 206 and the corresponding circular pipe 205. When there is no municipal sludge discharged from the discharge end of the opened other first electric valve 206, the controller 215 is directly used to close the motor 213 and the other first electric valve 206. When it is necessary to perform a filter press operation on the disinfected municipal sludge, the prepared waste gas treatment equipment (corresponding to the treatment principle, Fig.11 ) and wastewater treatment equipment (treatment principle corresponds to Fig.10 ) are connected to the ultra-high pressure laminate filter press equipment, and then the prepared wastewater treatment equipment (treatment principle corresponds to Fig.10 ) is also connected to the low-temperature belt dryer 103, and then the waste gas treatment equipment (treatment principle corresponds to Fig.11 ) is also connected to the low-temperature belt dryer 103, and the heat in the exhaust gas discharged by the low-temperature belt dryer 103 is recovered by using the prepared heat exchanger and applied to the sludge incinerator 104 (the waste heat recovery and the use principle of the sludge incinerator 104 correspond to Fig.12 ), and then prepare the flue gas treatment equipment (treatment principle corresponds to Fig.13) is connected to the sludge incinerator. When everything is ready, the disinfected urban sludge is first placed on the ultra-high pressure laminated filter press 102, and then the control box 106, the ultra-high pressure laminated filter press 102 and the filter press conditioner are used to dehydrate the urban sludge. Then the waste gas generated by the urban sludge is treated by the waste gas treatment equipment, and the waste water generated is also treated by the waste water treatment equipment. Then the mud cake is received by the designated equipment and place, and the received sludge is stored again. When the stored mud cake needs to be dried again, the mud cake is first transported from the storage place to the place where the sludge can be dried, and then the low-temperature belt dryer 103 and the control box 106 are used to dry the sludge. At this time, the waste water generated is treated by the waste water treatment equipment, and the waste gas generated is also treated by the waste gas treatment equipment. Then the dried sludge is placed in the sludge incinerator 104, and then the control box 1 is used to dry the sludge. 06. The sludge incinerator 104 cooperates with the prepared power generation equipment to perform power generation operations. At this time, the flue gas generated by the sludge incineration can be treated by the flue gas treatment equipment. When the ash generated in the above steps needs to be crushed, screened and graded, the ash is directly collected around the ash grading machine 105. Then, the ash placed in the ash grading machine 105 can be crushed by the cooperation of the ash grading machine 105 and the control box 106. Then, ash particles of the required size can be obtained by screening. That is, the cooperation of sludge deep dehydration and incineration can effectively reduce the thermal drying of sludge. At the same time, the sludge adopts the ultra-high pressure laminated filter pressing method under the physical state of room temperature, which can make the water filtered out without the heat energy loss of latent heat of vaporization, that is, the current sludge drying technology before incineration is not mature. The pure drying and water removal technology allows the water in the sludge to be removed at a high temperature, increasing the heat energy loss of latent heat of vaporization, reducing the sludge calorific value and reducing the subsequent power generation efficiency.

[0047] Among them, sealed bearings are commonly used parts in reality.

[0048] Among them, the generator 216 is electrically connected to the controller 215, which is mainly reflected in the electrical connection between the control board inside the generator 216 and the controller 215, and the controller 215 is electrically connected to the control box 106, which is mainly reflected in the electrical connection between the controller 215 and the power distribution unit inside the control box 106.

[0049] Among them, one of the three first electric valves 206 is located closest to the motor 213 , the middle first electric valve 206 is located closest to the plunger pump 302 , and the other first electric valve 206 is located closest to the cement platform 101 .

[0050] Ultra-high pressure laminated filter press 102 adopts the integrated technology of "surface activation wall breaking" + "mechanical filtration deep dehydration". Its working principle and process are as follows:

[0051] Sludge modification: The sludge after primary dehydration and the sludge modifier are mixed quickly and evenly in the sludge modification mixer. The main function of the modifier (using one of polyaluminium chloride, polyacrylamide, ferric chloride and aluminium chloride) is to destroy the cell wall and destabilise the colloid, thereby reducing the water holding capacity of the sludge, converting the bound water into "destabilised water", and making the sludge "granular" and "porous", which is beneficial to the water distribution and dehydration in the subsequent deep dehydration stage.

[0052] High-pressure dehydration: The modified sludge is transported to the continuous deep dehydration press to achieve sludge dehydration under high pressure and intensive force. The main principle is to repeatedly and multiple times press the modified sludge under high pressure to form 5-10mm porous flakes to ensure that the water is fully squeezed out after demoulding. The moisture content of the sludge after deep dehydration can reach 60%, the water holding capacity is greatly reduced, and the porosity of the mud cake is large. The moisture content of the sludge will continue to decrease after being placed and solidified.

[0053] The sludge incinerator 104 utilizes high temperature oxidation to convert organic matter in the sludge into carbon dioxide, water vapor and heat energy. This process is usually carried out in a closed incinerator. By controlling the temperature and oxygen supply in the furnace, it is ensured that the organic matter in the sludge can be fully burned. The working principle of the fluidized bed incinerator is: the furnace is lined with refractory materials, and the combustion chamber is formed by the air distribution plate below. The combustion chamber is divided into an upper dilute phase zone (suspension section) and a lower dense phase zone. There is a large amount of inert bed material (such as coal ash or sand, etc.) in the bed layer of the dense phase zone, which has a large heat capacity and can meet the heat required for evaporation of sludge water, thermal decomposition and combustion of volatiles. The air sent to the dense phase zone by the air distribution device makes the bed layer in a good fluidized state, and the temperature in the bed is uniformly and stably at 800℃-900℃, which is conducive to the decomposition and combustion of organic matter. The flue gas produced after incineration carries a small amount of solid particles and unburned organic matter into the dilute phase zone. The high-speed air flow sent in by the secondary air forms a rotating tangential circle in the center of the furnace, which makes the disturbance strong and the mixing sufficient, so that the unburned components can continue to burn.

[0054] The main working parts of the ash classifying machine 105 are two crushing rollers installed in parallel. Each crushing roller is arranged with a certain number of crushing teeth (tooth plates) along the axial direction, and rotates inward or outward according to the properties and parameters of the crushed materials. After the mixed material enters the crushing area, the material is discharged between the two teeth and between the comb plates on the side walls, but no oversized particles are discharged. Subsequently, the ash particles of the required size are screened out by the cooperation of the vibrating screen.

[0055] Among them, the ultra-high pressure laminated filter press 102, the low-temperature belt dryer 103, the sludge incinerator 104 (fluidized bed incinerator), the ash grading machine 105, the control box 106, the first electric valve 206, the motor 213, the fan 214, the controller 215 (PLC controller), the sensor 220 (gas flow sensor), the generator 216 (ozone generator), the second electric valve 218, the one-way valve 219 and the plunger pump 302 are all existing technologies, and their working principles are all public technologies. Their models can be selected according to actual conditions, and no excessive explanation is given here.
