[0022] Example

[0023] The waste gas purification device described in this embodiment is suitable for environmental protection engineering construction. Figure 1 As shown, it comprises a first box body 1, the front side wall of the first box body 1 is in an active state, the left side of the front side wall can be hinged to the first box body 1 through a pivot or a hinge, and the right side of the front side wall can be locked to the first box body 1 through a lock; therefore, the front side wall of the first box body 1 can be opened by opening the lock;

[0024] like Figure 1 and Figure 3 As shown, a support assembly for propping up the first box body 1 is provided at the bottom thereof; the support assembly may be two support plates 17 arranged left and right, and the top of the support plate 17 is fixed to the bottom of the first box body 1, thereby achieving the purpose of supporting the first box body 1;

[0025] In a specific implementation process, the support assembly can also be four support rods, which are distributed in a rectangular shape, and the tops of the four support rods are fixed to the bottom of the first box body 1, so as to achieve the purpose of supporting the first box body 1;

[0026] like Figure 1 As shown, an air inlet pipe 2 for discharging exhaust gas thereinto is arranged on the left side wall of the first box body 1, and an air outlet pipe 13 for discharging treated exhaust gas is arranged on the right side wall thereof; when the air inlet pipe 2 and the air outlet pipe 13 are specifically installed, mounting holes communicating with each other inside and outside are opened on the left and right side walls of the first box body 1, the air inlet pipe 2 is installed in the mounting hole on the left side of the first box body 1, and the air outlet pipe 13 is installed in the mounting hole on the right side of the first box body 1; when in use, the exhaust gas to be treated is discharged from the air inlet pipe 2 into the first box body 1, and then the purified exhaust gas is discharged through the air outlet pipe 13;

[0027] like Figure 1 As shown, an activated carbon net 18 for purifying the exhaust gas is vertically arranged in the first box 1. The activated carbon net 18 is a known product. The activated carbon net 18 is widely used to treat various organic gases and odorous gases, such as benzene, phenols, esters, alcohols, aldehydes, etc.; it can adsorb, concentrate and purify the exhaust gas, so that the treated exhaust gas can be directly discharged;

[0028] like Figure 1 As shown, an air intake cover 19 is fixed to the outlet end of the air intake pipe 2. As can be seen from the figure, a funnel-shaped structure is formed between the air intake cover 19 and the air intake pipe 2, wherein the inner diameter on the left side is smaller than the inner diameter on the right side. Therefore, through the design of the air intake cover 19, the exhaust gas can be blown onto the activated carbon net 18 more concentratedly;

[0029] like Figure 1 and Figure 2 As shown, a second box body 5 without a bottom is fixed on the top of the first box body 1, a connecting plate 8 is horizontally arranged in the second box body 5, and two limit plates 9 arranged left and right are fixed on the bottom of the connecting plate 8. A through hole for the limit plate 9 to penetrate into the first box body 1 is opened on the top of the first box body 1; the limit plate 9 is vertically arranged, and the top of the limit plate 9 is fixed to the bottom of the connecting plate 8; the through hole is connected from top to bottom, so through the design of the through hole, the limit plate 9 can move from the through hole into the first box body 1, thereby moving from the second box body 5 into the first box body 1;

[0030] like Figure 1 and Figure 2 As shown, a cylinder 7 is arranged between the connecting plate 8 and the inner top of the second box body 5, the rear cylinder head of the cylinder 7 is fixed to the inner top of the second box body 5, and the piston rod of the cylinder 7 is fixed to the top of the connecting plate 8; this section of the scheme as a whole constitutes a driving component for driving the limit plate 9 to move into the first box body 1; compared with the electric actuator, the cylinder 7 can work reliably under harsh conditions, and the operation is simple, and it can basically be maintenance-free; the cylinder 7 is good at reciprocating linear motion, and stable speed control can be simply achieved by simply adjusting the one-way throttle valve installed on both sides of the cylinder, which has also become the biggest feature and advantage of the cylinder drive system; because the piston rod of the cylinder 7 is fixed on the connecting plate 8, it can drive the connecting plate 8 to move up and down, and at the same time, the connecting plate 8 drives the limit plate 9 to move up and down. In the process of moving up and down, the limit plate 9 can be moved into the second box body 5 or into the first box body 1 through the action of the cylinder 7;

[0031] In the specific implementation process, the cylinder 7 in the driving assembly can also be replaced with a hydraulic cylinder. The effect of the hydraulic cylinder is similar to that of the cylinder 7. It converts hydraulic energy into mechanical energy and is a hydraulic actuator that performs linear reciprocating motion (or swinging motion). It has a simple structure and reliable operation. When it is used to achieve reciprocating motion, a deceleration device can be omitted, and there is no transmission gap and the motion is smooth. Therefore, it is widely used in the hydraulic systems of various machines. Therefore, when the hydraulic cylinder moves up and down, it can also drive the connecting plate 8 and the limit plate 9 to move up and down, thereby driving the limit plate 9 to slide into the first box body 1.

[0032] like Figure 1 and Figure 2 As shown, when the limit plate 9 moves into the first box body 1, the activated carbon net 18 is located between the two limit plates 9; Figure 2 It can be seen from the orientation in that after the limit plate 9 moves into the first box body 1, the limit plate 9 on the left is located on the left side of the activated carbon net 18, and the limit plate 9 on the right is located on the right side of the activated carbon net 18;

[0033] like Figure 1 and Figure 2 As shown, a water pump 4 is arranged in the second box body 5, and the water pump 4 is installed on the top of the first box body 1, and the water inlet end of the water pump 4 is connected to the water inlet pipe 3 communicating therewith, and a through hole communicating inside and outside is opened on the second box body 5, and the water inlet end of the water inlet pipe 3 passes through the through hole and is located on the outside of the second box body 5; the water outlet end of the water pump 4 is connected to the water outlet pipe 6 communicating therewith, and the water outlet end of the water outlet pipe 6 is fixed on the right side wall of the left limit plate 9, and the water outlet pipe 6 is connected to a branch pipe communicating therewith, and the water outlet end of the branch pipe is fixed on the left side wall of the right limit plate 9; the water outlet end of the water outlet pipe 6 and the water outlet end of the branch pipe are both installed with a plurality of nozzles 10 for spraying the activated carbon net 18; this section of the scheme as a whole constitutes a cleaning assembly for cleaning the activated carbon net 18; because the limiting plate 9 can be moved to the left and right sides of the activated carbon net 18 under the action of the driving assembly, and The water outlet pipe 6, the branch pipe and the nozzle 10 are arranged on the limit plate 9, so that when the limit plate 9 moves downward, the nozzle 10 can be driven to move to the left and right sides of the activated carbon net 18; when in use, the water inlet end of the water inlet pipe 3 is connected to the external water source, and then the water pump 4 is turned on. The water pump 4 discharges the water source through the water outlet pipe 6 and the branch pipe, and finally sprays it out through the nozzle 10. When spraying, the nozzle 10 can spray to the left and right sides of the activated carbon net 18, so as to clean the activated carbon net 18; therefore, after the limit plate 9 is driven by the driving component to move into the first box body 1, the cleaning component can be opened to clean the activated carbon net 18, so that there is no need to take the activated carbon net 18 out of the first box body 1 for cleaning, thereby improving the cleaning efficiency during the cleaning of the activated carbon net 18, and saving time and effort in operation;

[0034] In a specific implementation process, the nozzle 10 in the cleaning assembly can be replaced with a high-pressure nozzle, thereby improving the cleaning efficiency;

[0035] like Figure 1 and Figure 3 As shown, a first drain pipe 16 is provided on the first housing 1, and the first drain pipe 16 is connected to two second drain pipes 15 communicating therewith; drainage holes communicating with each other are provided at the bottom of the first housing 1 on both sides of the activated carbon net 18, and a water inlet end of one second drain pipe 15 is installed in the drainage hole on the left, and a water inlet end of another second drain pipe 15 is installed in the drainage hole on the right; this scheme as a whole constitutes a drainage assembly for discharging used wastewater; according to Figure 1 It can be seen that the second drain pipe 15 and the first drain pipe 16 form a "Y"-shaped structure, wherein the upper end of one second drain pipe 15 is located on the left side of the activated carbon net 18, and the other second drain pipe 15 is located on the right side of the activated carbon net 18. After the two second drain pipes 15 are installed, the second drain pipes 15 are both installed with switch valves; when in use, the switch valves on the second drain pipes 15 are opened, and the used waste water is discharged from the two second drain pipes 15 respectively, and finally collected in the first drain pipe 16. The first drain pipe 16 discharges the discharged waste water into a specified container, and then treats the waste water with harmful substances before discharging it into the environment;

[0036] In the specific implementation process, only one second drainage pipe 15 may be provided in the drainage assembly, and its position is preferably located on the left side of the activated carbon net 18, and then the wastewater on the right side of the activated carbon net 18 flows through the activated carbon net 18 to the left side of the activated carbon net 18, and then is discharged through the second drainage pipe 15;

[0037] like Figure 1 and Figure 2 As shown, a scraper 12 is provided in each through hole and is fitted with the hole wall, and the scraper 12 is fixed to the bottom of the corresponding limiting plate 9; because the limiting plate 9 is in two pieces, there are two through holes on the left and the right; so one of the scrapers 12 is located in the left through hole and is fixed to the bottom of the left limiting plate 9, and the other scraper 12 is located in the right through hole and is fixed to the bottom of the right limiting plate 9; when the scraper 12 is in use, because the scraper 12 is fixed to the bottom of the limiting plate 9, when the limiting plate 9 moves into the first box body 1, the scraper 12 will also move into the first box body 1, and the scraper 12 will contact the activated carbon net 18 during the downward movement, so that the scraper 12 can scrape off the stains on the surface of the activated carbon net 18, thereby achieving the purpose of simultaneous rinsing and scraping, and improving the cleaning efficiency; through the design of the scraper 12 fitting with the hole wall of the through hole, when the cleaning component is not in use, the scraper 12 can block the position of the through hole to avoid exhaust gas leakage from the position of the through hole as much as possible;

[0038] like Figure 1 As shown, a hot air blower 11 for drying the activated carbon net 18 is installed on the top of the first box body 1. When the hot air blower 11 is specifically installed, an air inlet pipe is installed at its air inlet end, and an air outlet pipe is installed at its air outlet end; when the air inlet pipe and the air outlet pipe are specifically installed, holes that communicate with the inside and outside are opened on the right side wall of the second box body 5 and the top of the first box body 1, the air inlet pipe is installed in the hole on the right side wall of the second box body 5, and the air outlet pipe is installed in the hole on the top of the first box body 1; when in use, turn on the hot air blower 11, and the hot air blower 11 can blow hot air into the first box body 1 through the air outlet pipe, so as to achieve the purpose of drying the activated carbon net 18. The activated carbon net 18 can be regenerated by drying, and it is ensured that the restored activated carbon net 18 meets the standard purification requirements;

[0039] like Figure 1 and Figure 2 As shown, the top and bottom of the activated carbon net 18 are both installed with a clamping strip 14, and the top and bottom of the first box body 1 are provided with a slide groove for the clamping strip 14 to slide forward and backward, and the clamping strip 14 and the slide groove are in a forward and backward sliding cooperation; because the clamping strip 14 is fixed on the activated carbon net 18, when the clamping strip 14 slides forward and backward in the slide groove, the activated carbon net 18 can be driven to move, and by taking the clamping strip 14 out of the slide groove, the activated carbon net 18 can be driven to be taken out of the first box body 1, so when the activated carbon net 18 is damaged and needs to be replaced later, it is convenient to replace it;

[0040] During specific use: first, the exhaust gas is injected from the air inlet pipe 2, and the exhaust gas is purified through the activated carbon net 18, and the purified exhaust gas is discharged through the exhaust pipe 13; when the activated carbon net 18 needs to be cleaned after being used for a period of time, the driving component is used to drive the limit plate 9 to move to the left and right sides of the activated carbon net 18, and then the cleaning component is opened to clean the left and right sides of the activated carbon net 18, and the waste water after cleaning is discharged through the drainage component; in this use process, the design that the activated carbon net 18 can be directly cleaned is used to avoid the problem of cumbersome operation caused by taking the activated carbon net 18 out of the first box body 1 for cleaning, and the cleaning efficiency is improved in the process of cleaning the activated carbon net 18, which reduces the burden on the staff.
