Description

Technical Field

[0001] The utility model relates to the technical field of harmful gas treatment, in particular to a harmful gas treatment device for environmental protection engineering. Background Art

[0002] Harmful gases refer to those gases that have an adverse impact on the health of humans or animals, or even if they do not have a direct impact on health, they may cause discomfort or affect comfort. Harmful gases can be further classified into toxic gases, flammable gases, and asphyxiating gases. They can be divided into primary pollutants and secondary pollutants. The emission of harmful gases into the atmosphere will cause air pollution and affect the overall air quality. Therefore, before emission, harmful gases need to be treated.

[0003] A patent with the patent authorization announcement number CN218421618U discloses a harmful gas treatment device, including a vertical air inlet pipe. A plurality of openings one are provided below the side wall of one side of the air inlet pipe, and a plurality of openings two are provided above. Filter mechanisms are respectively inserted into the openings one, and adsorption mechanisms are respectively inserted into the openings two. Although the above patent can continuously treat harmful gases by setting a plurality of filter mechanisms and adsorption mechanisms when cleaning the filter screen and replacing the activated carbon plate, there are still deficiencies in actual use. For example, when there is a large amount of dust in the harmful gas, the dust will accumulate on the filter screen and the activated carbon plate, easily causing the filter screen and the activated carbon plate to be quickly blocked. This not only reduces the utilization rate of the filter screen and the activated carbon plate, but also increases the cleaning and replacement frequency of the filter screen and the activated carbon plate.

[0004] Therefore, there is a particular need for a harmful gas treatment device for environmental protection engineering to solve the problems existing in the prior art. Summary of the Utility Model

[0013] The utility model realizes the dust reduction of harmful gases by setting a dust reduction mechanism. When the water pump operates, water is transported into the atomizing nozzle, and the water is atomized into water mist by the atomizing nozzle and sprayed into the intake pipe.

[0023] Embodiment: A harmful gas treatment device for environmental protection engineering, as shown in Figures 1-5 Figure [not provided in the original, assume it's a reference figure number], which includes an intake pipe 1, a filtration chamber 3, a U-shaped connecting plate 40, an activated carbon filter plate 41, bolts 42, a spray chamber 5, a liquid storage tank 60, a piston 61, a liquid pump 62, a connecting pipe 63, an annular water pipe 64, a solenoid valve 65, a gas-liquid separator 7, an exhaust pipe 80, and a protective net 81. A flange is provided on the front side of the intake pipe 1 to assist in connecting the exhaust pipe of harmful gases. The filtration chamber 3 is connected to the rear side of the intake pipe 1. A plurality of activated carbon filter plates 41 evenly spaced and distributed in a straight line are inserted into the filtration chamber 3. The upper end of the activated carbon filter plate 41 is clamped with a U-shaped connecting plate 40, and the U-shaped connecting plate 40 is fixed to the upper end of the activated carbon filter plate 41 by symmetrically distributed bolts 42. A handle for assisting extraction is provided at the upper end of the U-shaped connecting plate 40. The rear side of the filtration chamber 3 is connected to the spray chamber 5. The upper left side of the spray chamber 5 is connected to the liquid storage tank 60 by bolts. A piston 61 is plugged into the upper part of the liquid storage tank 60. The center position on the right side of the liquid storage tank 60 is connected to the liquid pump 62 by bolts. The liquid pump 62 is connected to the connecting pipe 63 on the right side. The annular water pipes 64 distributed left and right are connected to the inside of the spray chamber 5 by bolts. The lower part of the connecting pipe 63 is divided into two ends respectively connected to the two annular water pipes 64. A plurality of water outlets distributed circumferentially are provided on the annular water pipe 64 to evenly spray the oxidant into the inside of the spray chamber 5. The solenoid valves 65 distributed left and right are connected to the inside of the spray chamber 5 by bolts. The two annular water pipes 64 are located between the two solenoid valves 65. Another piston 61 is plugged into the lower part of the spray chamber 5. The piston 61 is made of sealing rubber and has a relatively slow compression stress, which can achieve a good sealing effect. The right side of the spray chamber 5 is connected to the gas-liquid separator 7. The top of the gas-liquid separator 7 is connected to the exhaust pipe 80 by bolts. A protective net 81 for preventing foreign dust or objects from entering is butted inside the upper end of the exhaust pipe 80. It also includes a dust removal mechanism, and a dust removal mechanism for removing dust from harmful gases is provided inside the intake pipe 1.

[0024] As shown in Figure 1 and Figure 2 It should be noted that the reference figure number in the translation of item is assumed as the original text doesn't provide it. You may need to correct it according to the actual figure number in the original patent document.As shown in the figure, the dust-removing mechanism includes a water pump 20, an atomizing nozzle 21, a guiding frame 22, a lifting plate 23 and a return spring 24. The upper part of the intake pipe 1 is connected with the water pump 20 by bolts. The upper side of the water pump 20 is provided with a water inlet. The atomizing nozzle 21 is connected to the lower side of the water pump 20 by bolts and is located in the upper part of the intake pipe 1. The lower part of the intake pipe 1 is connected with the guiding frame 22 by welding. The lifting plate 23 is slidably connected to the guiding frame 22. The circular side edge of the lifting plate 23 is closely attached to the inner wall of the lower part of the intake pipe 1. The outside of the guiding frame 22 is sleeved with symmetrically distributed return springs 24. The two ends of the return spring 24 are respectively connected with the lifting plate 23 and the guiding frame 22.

[0025] It should be noted that the staff should grasp the control time of the solenoid valves 65 on both sides to ensure that the harmful gases enter the spray chamber 5 in batches for purification treatment, effectively improving the treatment quality of the harmful gases.

[0026] First, the staff pulls up the upper piston 61 to open the liquid storage tank 60 and pours the oxidant into the liquid storage tank 60. After the pouring is completed, the upper piston 61 is pushed back downward to close the liquid storage tank 60. Then, the external water supply pipe is connected to the water inlet of the water pump 20, and then the water pump 20 is turned on. The water pump 20 runs to transport water to the atomizing nozzle 21, so that the water is atomized into water mist through the atomizing nozzle 21 and sprayed into the air intake pipe 1. Then, the harmful gas discharge pipe is connected to the air intake pipe 1 to transport the harmful gas into the air intake pipe 1. At this time, the atomizing nozzle 21 continuously sprays water mist to contact the dust in the harmful gas to achieve dust reduction of the harmful gas. The harmful gas after dust reduction enters the filter chamber 3, passes through multiple activated carbon filter plates 41 for filtration and purification, and then controls the left electromagnetic valve 65 to open the spray chamber, so that the filtered harmful gas enters the spray chamber. After an appropriate amount of harmful gas enters the spray chamber, the left electromagnetic valve 65 is controlled to close the spray chamber, and the liquid pump 62 is turned on. The liquid pump 62 runs to transport the oxidant in the liquid storage tank 60 from the connecting pipe 63 to the annular water pipe 64, and then evenly sprays it from the annular water pipe 64 to the spray chamber to contact the harmful gas, thereby performing secondary purification on the harmful gas. After the purification is completed, the right electromagnetic valve 65 is controlled to open the spray chamber. The purified gas enters the gas-liquid separator 7 to separate the residual oxidant, which is discharged from the discharge pipe, and the separated oxidant flows back into the spray bin. During the treatment process, the water formed by the water mist gathers at the lower part of the inlet pipe 1 and is received by the lifting plate 23. When more and more water accumulates, the lifting plate 23 moves downward under the weight of the water to open the water inlet pipe, and the return spring 24 is compressed accordingly. After the water is discharged, the return spring 24 returns to its original state, prompting the lifting plate 23 to move upward to close the water inlet pipe. In this way, the water accumulated in the water inlet pipe is discharged intermittently, and the lifting plate 23 will not open the water inlet pipe too much to avoid The harmful gas in the water inlet pipe leaks, and the used oxidant gathers in the spray chamber. After the harmful gas is treated, the harmful gas discharge pipe is disconnected from the air inlet pipe 1, and the external water supply pipe is disconnected from the water inlet of the water pump 20. Then, the lower piston 61 is pulled downward to open the spray chamber and recover the oxidant. After the recovery is completed, the lower piston 61 is pushed upward to close the spray chamber. When the activated carbon filter plate 41 needs to be replaced, the activated carbon filter plate 41 is pulled out from the filter chamber 3, the bolts 42 are unscrewed, and the activated carbon filter plate 41 is replaced. After the replacement is completed, the bolts 42 are screwed back and the activated carbon filter plate 41 is inserted back into the filter chamber 3.
