In order to protect the environment, manufacturers will install and use dust removal devices at the flue gas outlet. After the boiler exhaust gas enters the equipment, it first passes through the dust removal part and uses physical methods such as filtration and centrifugal separation to remove particulate matter in the exhaust gas. Then, the equipment uses the waste heat recovery system to recycle the waste heat in the exhaust gas.

When the flow rate changes, especially when the flow rate drops due to blockage of the primary filter component 401, the remote controller 4021 determines whether an alarm needs to be issued based on a preset threshold value. If the flow rate is lower than the set value, the remote controller 4021 controls the alarm 4023 to issue a warning signal to alert the operator. If the situation is serious, the alarm 4024 is controlled to sound an alarm so that the operator can remove and replace the top frame 4011 in time. At the same time, the bottom frame 4011 works normally, thereby ensuring the stability of the exhaust gas flow rate and improving the stability of purification and dust removal.

[0050] like Figure 5As shown, the exhaust component 403 includes a suction pipe 4031 connected to the bottom right side of the box body 2, and a fan 4032 is bolted to the left side of the top of the bottom plate 1, the suction end of the fan 4032 is connected to the right side of the suction pipe 4031, and the output end of the fan 4032 is connected to the exhaust pipe 4033.

[0052] Brief description of the use process: First, after the high-temperature boiler exhaust gas enters the box 2 from the air inlet pipe 3, the primary filter 4014 inside the frame 4011 takes effect first, intercepting larger particulate matter, such as larger dust and soot, the middle filter 4013 further filters smaller particles, and the carbon mesh 4012 absorbs some odors and harmful gases. Through these three levels of filtration, most of the larger particulate matter in the exhaust gas is effectively removed, reducing the burden of subsequent filtration. In this process, the hot wire wind speed sensor 4022 on the left side of the box 2 monitors the flow rate of the exhaust gas in the box 2 in real time and transmits the data to the remote controller 4021. When the flow rate changes, especially when the flow rate decreases due to blockage of the primary filter component 401, the remote controller 4021 determines whether an alarm needs to be issued based on a preset threshold value. If the flow rate is lower than the set value, the remote controller 4021 controls the alarm 4023 to issue a warning signal to remind the operator to pay attention. If the situation is more serious, the alarm 4024 is controlled to sound an alarm so that the operator can promptly check the top frame 401 1 is taken out and replaced. At the same time, the frame 4011 at the bottom carries various filters to work normally, thereby ensuring the stability of the exhaust gas flow rate and improving the stability of purification and dust removal. Then, the fan 4032 on the left side of the top of the bottom plate 1 generates negative pressure through the suction pipe 4031 to extract the preliminarily filtered exhaust gas from the box 2. The fan 4032 overcomes factors such as pipeline resistance to ensure that the exhaust gas can flow smoothly in the system and quickly transport the exhaust gas to the heat exchange box 4041. The heat exchange box 4041 receives the exhaust gas from the fan 4032. Gas, low-temperature water or other heat exchange medium flows in the hot water exchange pipe 4043 inside the heat exchange box 4041. When the high-temperature exhaust gas passes through the heat exchange box 4041, the heat is transferred to the medium in the hot water exchange pipe 4043 through heat exchange, thereby realizing waste heat recovery. The recovered waste heat can be used for heating, hot water supply or other industrial production processes, thereby improving energy utilization efficiency and reducing the exhaust gas temperature, thereby creating better conditions for subsequent purification treatment.

[0060] Brief description of the use process: First, after the exhaust gas after heat exchange enters the tower body 5 through the delivery pipe 4042, the water pump 7011 located on the top right side of the bottom plate 1 starts to work. The water pump 7011 extracts the filtered purified liquid from the bottom of the tower body 5 and delivers it to the spray head 7013 through the water delivery pipe 7012. The spray head 7013 sprays the purified liquid, such as alkali liquid or water, to the exhaust gas entering the tower body 5. The purified liquid reacts chemically with the harmful substances in the exhaust gas to absorb or neutralize the harmful substances, thereby achieving preliminary purification of the exhaust gas. During the process, after the purified liquid falls, it first passes through the bearing net 7022 set in the bearing frame 7021 on the right side inside the tower body 5. The bearing net 7022 intercepts larger impurities and solid particles. The filtrate net 7023 bolted at the bottom of the bearing net 7022 further filters the fine particles in the purified liquid. The purified liquid after filtration can be recycled, which reduces the purification cost. Then the filter membrane plate 7032 can filter the tiny particles and some harmful substances in the purified liquid, and the adsorption net 7033 removes specific harmful substances in the purified liquid through adsorption, further improving the purification effect of the purified liquid. Then the exhaust gas continues to flow after preliminary purification by spraying. Subsequently, the exhaust gas passes through the ULPA filter and the activated carbon layer net 7043 set in the frame 7041 on the right side inside the tower body 5. The frame 7041 provides support for the ULPA filter and the activated carbon layer net 7043. The ULPA filter can filter out most of the tiny particles, and the filtration efficiency of particles with a diameter of 0.1-0.3 microns is usually above 99.999%, which can effectively remove In addition to the fine particles in the exhaust gas, the activated carbon layer net 7043 absorbs the odor and harmful gases in the exhaust gas, making the exhausted exhaust gas cleaner and odorless. Finally, the exhaust gas after odor removal reaches the top side of the tower body 5. The electric heating tube 7051 heats the exhaust gas to remove moisture in the exhaust gas and realize the drying function. The support blocks 7052 on both sides of the top side of the tower body 5 are fixed with ultraviolet sterilization lamp panels 7053. The ultraviolet sterilization lamp panels 7053 emit ultraviolet rays to sterilize and disinfect the exhaust gas, thereby improving the air quality of the exhausted exhaust gas.
