Description

Technical Field

[0001] The invention relates to the technical field of flue gas purification equipment, in particular to a high temperature and high humidity resistant incineration smoke emission treatment device. Background Art

[0002] Hot smoke generally refers to smoke produced in a high temperature environment, which comes from a variety of different processes.

[0003] The existing patent with publication number CN108654308A discloses a factory smoke emission purification treatment device, including a fixed bottom ring, a first elastic band, a second elastic band, a first fixed ring, a second fixed ring, a first snap ring, a second snap ring, a first shell, a second shell, a third shell, a water sponge layer, a fiber adsorption layer, an exhaust fan, a dust net, a sealing rubber pad, and a sealing ring. The fixed bottom ring is connected with the first fixed ring above, the first elastic band and the second elastic band are connected above the first fixed ring, the first shell is arranged above the first elastic band and the second elastic band, the first shell is arranged inside the water sponge layer, the first shell is connected above the second shell, the second shell is arranged inside the fiber adsorption layer, and the polluted gas adsorption layer is arranged behind the fiber adsorption layer; the invention can be installed at the smoke emission place, effectively filters harmful gases and reduces environmental pollution.

[0004] However, the factory smoke emission purification treatment device disclosed in the above patent has a serious deformation of the filter structure when treating high-temperature smoke due to the insufficient heat resistance of the material, which affects the filtering effect of the high-temperature smoke, and the air discharged into the atmosphere still contains particulate matter. The dust collectors with the best heat resistance on the market are bag pulse dust collectors and ceramic dust collectors. Bag pulse dust collectors use pulse blowing to clean dust. By adjusting the frequency and intensity of the blowing pulses, the permeability of the bag can be maintained and the filtering efficiency can be improved. However, the scope of application is limited to low-humidity smoke treatment. When facing humid smoke, it will cause dust to form inside the bag. The adhesive blocks the filter holes and affects the filtering effect. Ceramic dust collectors have excellent filtering performance and reliability when dealing with high-temperature and high-humidity flue gases and can remove fine particles. However, ceramic dust collectors are very prone to damage during transportation, which increases transportation costs. After long-term use, a large amount of dust and dirt will accumulate inside the ceramic dust collector, which makes it difficult to clean the inside of the ceramic dust collector, which increases cleaning costs. At the same time, high-temperature smoke also causes great damage to the vacuum cleaner itself, requiring the high-temperature flue gas to be cooled, but ordinary ceramic dust collectors cannot cool the high-temperature flue gas.

[0005] Therefore, the existing demand cannot be met. Therefore, the present invention proposes a high temperature and high humidity resistant incineration smoke emission treatment device. Summary of the invention

DETAILED DESCRIPTION

[0050] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0051] Embodiment 1

[0052] See also Figure 1-Figure 10 This embodiment provides a high temperature and high humidity resistant incineration smoke emission treatment device, comprising:

[0053] The smoke exhaust heat exchange mechanism 100 comprises a box 101, a smoke exhaust pipe 102, a first water cooling component and a second water cooling component;

[0054] The smoke exhaust pipe 102 is connected to the box 101 and is used to discharge the filtered smoke. The first water cooling component is used to cool the smoke that enters the box 101 for filtering. The second water cooling component is used to cool the smoke that enters the box 101 for secondary cooling.

[0055] The pre-heat exchange mechanism 200 includes a heat exchange cylinder 201, a cold air pipe 202, a smoke inlet pipe 203 and an air cooling component;

[0056] The cold air pipe 202 and the smoke inlet pipe 203 are respectively connected to the heat exchange tube 201 . The smoke inlet pipe 203 is used to introduce smoke into the heat exchange tube 201 for heat exchange treatment. The air cooling component is used to cool the smoke introduced by the smoke inlet pipe 203 .

[0057] As can be seen from the above, the high-temperature flue gas is first subjected to preliminary air cooling treatment through the preheat exchange mechanism 200. The high-temperature flue gas enters the heat exchange cylinder 201 of the preheat exchange mechanism 200 from the smoke inlet pipe 203. At this time, the cold air introduced by the cold air pipe 202 exchanges heat with the high-temperature flue gas in the heat exchange cylinder 201. In this process, the cold air absorbs the heat in the flue gas, so that the temperature of the flue gas is initially reduced. The air cooling method not only effectively reduces the heat of the flue gas, but also creates favorable conditions for subsequent cooling treatment. The temperature of the flue gas after air cooling treatment by the preheat exchange mechanism 200 has been reduced, but further treatment is still required to meet the emission standards. Subsequently, these flue gases that have undergone preliminary cooling are introduced into the box 101 of the exhaust heat exchange mechanism 100. Inside the box 101, the flue gas first encounters the first water-cooling cooling component. This component exchanges heat with the flue gas through water or other coolants, transfers the heat in the flue gas to the coolant, and further reduces the temperature of the flue gas. If the cooling effect of the first water-cooling component is not enough to meet the requirements, the second water-cooling component is used as an auxiliary to continue cooling the flue gas. The coordinated work of the two water-cooling components ensures that the flue gas can reach the required temperature standard before being discharged. The first water-cooling component, as the main cooling means, undertakes most of the cooling tasks; while the second water-cooling component is used as a supplement to provide additional cooling capacity when the cooling effect of the first water-cooling component is not good. This design not only ensures the cooling effect, but also improves the flexibility and reliability of the system.

[0058] The first water-cooling component includes a filter element 1011, and a mounting plate 1013 and a bottom plate 1012 are fixedly disposed at both ends of the filter element 1011, respectively. The filter element 1011, the bottom plate 1012 and the mounting plate 1013 form a filter part, and each of the filter parts is provided with a heat exchange groove connected from top to bottom, and a heat exchange pipe 1041 is provided in the heat exchange groove;

[0059] The filter parts are provided in multiple and are distributed in a rectangular array. The heat exchange tubes 1041 correspond to the filter parts one by one. A connecting tube is provided between two adjacent heat exchange tubes 1041. The multiple heat exchange tubes 1041 and the connecting tube form a main heat exchange part 104. The upper and lower ends of one side of the main heat exchange part 104 are respectively provided with a water inlet pipe and a water outlet pipe.

[0060] The second water-cooling component includes an auxiliary heat exchange part 103, and the auxiliary heat exchange part 103 includes a spray pipe 1032 arranged at the bottom of each filter part, each of the spray pipes 1032 is connected through a first connecting pipe, and a plurality of the spray pipes 1032 and the first connecting pipe form a spray part, a valve pipe 1033 is provided on one side of the spray part, and each of the spray pipes 1032 is provided with a clamping groove;

[0061] The auxiliary heat exchange part 103 also includes a connecting pipe 1031 arranged at the top of each filter element 1011, and multiple connecting pipes 1031 are connected through a second connecting pipe. Each of the connecting pipes 1031 can be extended and a clamping piece is provided at the port facing the lower end of each connecting pipe 1031. Multiple connecting pipes 1031 and the second connecting pipe form an assembly component, and a valve pipe 1033 is provided on one side of the assembly component.

[0062] The valve pipe 1033 connected to the spraying element and the valve pipe 1033 connected to the assembly element are connected through a hose, so as to enable the second water cooling component to re-assist water cooling or not to assist water cooling of the filter element 1011 .

[0063] The air cooling component includes a temperature reduction and flow limiting component movably arranged in the heat exchange cylinder 201 for limiting the flow rate of smoke entering the box body 101 and cooling the smoke, and a driving component for driving the temperature reduction and flow limiting component to reduce temperature and limit flow.

[0064] The temperature reduction and flow limiting member comprises a disc 2014 slidably arranged on the heat exchange cylinder 201, the disc 2014 is provided with a plurality of smoke holes 2015, the disc 2014 is also provided with a plurality of smoke blocking plates 2016, the smoke holes 2015 and the smoke blocking plates 2016 correspond one to one, and the plurality of smoke holes 2015 are evenly distributed in a circle along the center of the disc 2014, and each of the smoke blocking plates 2016 is hinged to the disc 2014;

[0065] A sleeve 2012 is provided at the center of the lower end surface of the disk 2014 , and a plurality of stirring plates 2013 are evenly provided on the circumference of the sleeve 2012 .

[0066] The driving member includes a motor 2011 and a rotating shaft 20121 arranged in and connected to the sleeve 2012, one end of the rotating shaft 20121 is powered by the output end of the motor 2011, a rotating disk 20122 and a sleeve 20123 are sequentially sleeved on the circumference of the rotating shaft 20121 from top to bottom, the rotating disk 20122 is rotatably connected to the rotating shaft 20121, a first bevel gear 20124 rotatably connected to the sleeve 20123 is provided on the lower end surface of the rotating disk 20122, a second bevel gear 20125 is rotatably provided at one end of the sleeve 20123, the first bevel gear 20124 and the second bevel gear 20125 are vertically distributed and meshed with each other, a limiting column 20126 is provided on one side of the second bevel gear 20125, a slide groove is obliquely provided on the inner side of the heat exchange cylinder 201, and the limiting column 20126 is slidably connected to the heat exchange cylinder 201 through the slide groove.

[0067] As can be seen from the above, first, the high-temperature flue gas enters the heat exchange cylinder 201 of the pre-heat exchange mechanism 200, and performs preliminary heat exchange with the cold air introduced through the cold air pipe 202. At this time, the driving member in the pre-heat exchange mechanism 200 is started, and the motor 2011 drives the rotating shaft 20121 to rotate, thereby driving the disc 2014 to rotate in the heat exchange cylinder 201. The smoke holes 2015 and the smoke blocking plate 2016 on the disc 2014 dynamically adjust the opening with the rotation, limit the amount of smoke passing through, and increase the contact time and area between the smoke and the cold air, so as to promote the rapid transfer of heat. At the same time, a plurality of spoilers are intermittently distributed in the heat exchange cylinder 201 toward one end of the box 101, and at the same time, the stirring plate 2013 at the lower end of the disc 2014 rotates with the disc 2014 to stir the cold air and the flue gas, further improving the pre-cooling effect, and ensuring that the flue gas is pre-cooled to below 80 degrees Celsius before entering the exhaust heat exchange mechanism 100. Subsequently, the flue gas whose temperature drops below 80 degrees Celsius enters the housing 101 of the smoke exhaust heat exchange mechanism 100. In the housing 101, the flue gas is first further cooled by the first water-cooling cooling component. The first water-cooling cooling component is composed of a main heat exchange part 104 consisting of a filter element 1011 and a heat exchange tube 1041. The cooling water circulates in the heat exchange tube 1041 and performs heat exchange with the flue gas passing through the filter element 1011 to reduce the flue gas temperature. In this process, the filter element 1011 not only plays a filtering role, but also serves as a medium for heat exchange. As time goes by, the cooling efficiency of the first water-cooling cooling component will gradually decrease. At this time, the system automatically starts the second water-cooling cooling component as a supplement. Through the quick cooperation of the clamping member and the clamping groove, the spray pipe 1032 and the connecting pipe 1031 form an auxiliary heat exchange part 103 to perform secondary heat exchange on the filter element 1011. When the main heat exchange unit 104 has a good heat exchange effect on the filter element 1011, the spray pipe 1032 sprays cooling water to the filter element 1011, directly sprays and cleans the flue gas in the filter element 1011, and the flushing water is collected and sprayed through the sewage pipe and recycled. In this way, the second water-cooling and cooling component effectively supplements the cooling capacity of the first water-cooling and cooling component, ensuring the continuous decrease in the flue gas temperature. Finally, in order to maintain the filtering efficiency and heat exchange performance of the filter element 1011, the filter element 1011 needs to be cleaned regularly. During the cleaning process, the operation of the smoke exhaust heat exchange mechanism 100 can be suspended, and the filter element 1011 can be quickly disassembled and taken out for cleaning or replacement. After cleaning, the filter element 1011 is reinstalled back into the box 101, and the system resumes normal operation.

[0068] Embodiment 2

[0069] Based on Example 1, please refer to Figure 1-Figure 10The high temperature and high humidity resistant incineration smoke emission treatment device further comprises a processor, the processor is configured with a central control system for controlling the temperature according to the smoke temperature conditions in the smoke exhaust heat exchange mechanism 100 and the pre-heat exchange mechanism 200, the central control system is equipped with a sensor module, a data processing module and a control module;

[0070] The sensor module includes an air cooling unit and a water cooling unit. The air cooling unit obtains the smoke temperature in the pre-heat exchange mechanism 200 and generates air intake information. The water cooling unit is used to obtain the smoke temperature in the exhaust heat exchange mechanism 100 and generate smoke information, and obtain the particle size information of the smoke in the exhaust heat exchange mechanism 100.

[0071] The data processing module includes a preprocessing unit, a cooling unit and a filtering unit. The preprocessing unit is configured with a comparison strategy. The filtering unit is configured with a purification strategy. The comparison strategy is used to obtain intake information, compare it with a first temperature threshold and generate control information, and control the motor 2011 based on the control information. The cooling unit is configured with a water cooling strategy. The water cooling strategy is used to obtain smoke information and control the first water cooling component to water cool the filter element 1011. The purification strategy includes smoke logic and granularity logic. The smoke logic is used to obtain smoke information, compare it with a second temperature threshold and generate purification information, and determine whether to perform auxiliary cooling through a second water cooling component based on the purification information. The granularity logic includes obtaining granularity information, comparing it with the granularity threshold and generating cleaning information, and controlling the second water cooling component to clean the filter element 1011 based on the cleaning information.

[0072] The specific steps of controlling the motor 2011 based on the comparison strategy include:

[0073] If the comparison strategy detects that the temperature information in the intake air information is lower than the first temperature threshold, a standby instruction is generated, and the standby instruction is used to control the drive shaft of the motor 2011 not to rotate;

[0074] If the comparison strategy detects that the temperature information in the intake air information is higher than the first temperature threshold, a startup instruction is generated, and the startup instruction is used to control the motor 2011 to drive the shaft to rotate, thereby disturbing the flue gas and cold air in the pre-heat exchange mechanism 200 to make them fully mixed;

[0075] If the comparison strategy detects that the temperature information in the intake air information is lower than the first temperature threshold after air cooling, a uniform speed instruction is generated, and the uniform speed instruction is used to control the drive shaft of the motor 2011 to rotate at a uniform speed;

[0076] If the comparison strategy detects that the temperature information in the intake air information is still higher than the first temperature threshold after air cooling, an acceleration instruction is generated, and the acceleration instruction is used to control the motor 2011 to drive the shaft to rotate faster, thereby further cooling the flue gas in the pre-heat exchange mechanism 200.

[0077] If purification information is obtained but cleaning information is not obtained, an auxiliary instruction is generated, and based on the smoke information, the smoke temperature in the smoke information is compared with the second temperature threshold. If the smoke temperature is higher than the second temperature threshold, the b channel is connected through a hose, and the spray component and the assembly component are controlled to be connected to each other to form a second water cooling component, and the filter element 1011 is auxiliary cooled by water;

[0078] If the purification information is not obtained and the cleaning information is obtained, a second auxiliary instruction is generated. Based on the particle size information, when the particle size concentration in the particle size information is compared with the particle size threshold, if the particle size concentration is higher than the particle size threshold, the a channel is connected through the hose, and the spray element is controlled to rinse the filter element 1011;

[0079] For the filter element 1011 flushed by the spray element, the particle size information is reacquired at this time, and the particle size concentration in the particle size information is compared with the particle size threshold. If the particle size concentration is still higher than the particle size threshold, an enhancement signal is generated, and the enhancement signal is used to increase the water flow of the spray element.

[0080] As can be seen from the above, after the central control system is started, the sensor module first performs real-time detection of smoke temperature and smoke particle concentration at key locations such as the pre-heat exchange mechanism 200 and the smoke exhaust heat exchange mechanism 100. These data are quickly transmitted to the data processing module and compared with the internal preset thresholds.

[0081] When the sensor module detects that the smoke temperature in the pre-heat exchange mechanism 200 is higher than the set temperature threshold, the data processing module marks this information and transmits it to the data processing module.

[0082] The data processing module issues precise instructions to adjust the speed of the motor 2011 according to the received signal. By changing the speed of the motor 2011, the rotation speed of the disc 2014 can be adjusted, thereby controlling the opening of the smoke blocking plate 2016 and the stirring effect of the stirring plate 2013 on the cold air and smoke, thereby achieving precise control of the pre-cooling process.

[0083] The sensor module continuously monitors the temperature of the filter element 1011 in the smoke exhaust heat exchange mechanism 100. When the data processing module finds that the temperature after being processed by the main heat exchange unit 104 is lower than the temperature threshold, the central control system will maintain the current operating state.

[0084] If the temperature is still higher than the threshold but has not reached the emergency alarm level, the central control system will first try to perform preliminary flushing and cooling through the spray pipe 1032. The ball valve 10331 rotates the connecting valve pipe 1033 through the connecting shaft 10332. At this time, the data processing module issues a rotation command to control the rotation of the ball valve 10331, and the upper valve pipe 1033 is connected to the lower valve pipe 1033 through the hose to form a channel a. Figure 5 The middle arrow indicates the direction of water flow. The water flows from the upper valve tube 1033 through the first a channel, the hose and the second a channel in sequence and is sprayed out through the spray pipe 1032. The spray pipe 1032 starts to flush the filter element 1011.

[0085] During the flushing process, the sensor module continues to monitor the smoke particle concentration in the filter element 1011. If the concentration drops below the threshold, the data processing module will mark and instruct the data processing module to increase the water flow rate of the spray pipe 1032 to further improve the flushing effect.

[0086] If the temperature of the filter element 1011 is still higher than the threshold after the initial flushing, the central control system will start the secondary water cooling heat exchange process. The data processing module sends a rotation command to control the ball valve 10331 to continue to rotate, and controls the connecting pipe 1031 to descend and connect with the spray pipe 1032 through the connecting piece and the connecting groove, and connects the upper valve pipe 1033 with the lower valve pipe 1033 through the hose to form channel b. Figure 5 In the embodiment, water flows from the upper valve pipe 1033 through the first b channel, the connecting pipe 1031, the spray pipe 1032 and the second b channel in sequence and is discharged through the second b channel. The water cools the filter element 1011 according to this flow process. At this time, the spray pipe 1032 and the connecting pipe 1031 work together to cool the filter element 1011 more efficiently.

[0087] If the temperature of the filter element 1011 is still higher than the temperature threshold after dual processing by the main heat exchange unit 104 and the auxiliary heat exchange unit 103, or the smoke particle concentration continues to exceed the standard, the data processing module will mark this emergency situation and immediately transmit a signal to the alarm module, which is set on the box 101.

[0088] Based on these emergency signals, the data processing module issues instructions to control the alarm module to sound an alarm, prompting the operator to intervene. At the same time, the central control system automatically adjusts to a safe mode, reduces the smoke flow or temporarily shuts down some functions to prevent damage to the device or further safety accidents.
