Problems solved by technology

[0003] However, because the silt layer has been fermented for a long time, it generally contains a lot of toxic gases, such as hydrogen sulfide, ammonia and methane, so the dredging workers first need to separate a certain distance from the top of the culvert before dredging. Set up exhaust fans and blowers to ventilate the interior of the culvert before dredging can be carried out, and during the dredging work, dredging workers also need to wear gas masks
[0004] The above-mentioned existing technical solutions have the following defects: dredging workers need to stir the mud layer when dredging, so that a large amount of toxic gas hidden in the mud layer is emitted into the space inside the culvert, and then the inside of the culvert The content of toxic gases in the air has been greatly increased. Although there are ventilation measures and the dredging workers wear gas masks, but the dredging workers have been in the air environment with high levels of toxic gases for a long time, which is still very dangerous, so it needs to be improved.

Embodiment 1

[0038] Embodiment one, with reference to figure 1 and figure 2 , is a system for air treatment in the culvert disclosed by the present invention, which can first turn the silt in the culvert 1 before the dredging work, so that the toxic gas in the silt layer can be diffused and discharged , so that less toxic gas is discharged from the sludge layer when the dredging work is in progress, and the safety of the dredging work is improved. Fans 3 are arranged at intervals and communicate with the outside world respectively, and also include a dump truck 4 for turning the mud layer and a winch 5 for driving the dump truck 4 to move in the hidden culvert 1. There are two winches 5, and two Hoist 5 is respectively located in the both sides of dumping car 4.

[0039] refer to figure 1 and figure 2, before the dredging workers carry out the dredging work, first put two winches 5 and a dredger 4 into the hidden culvert 1, and the dumper 4 is between the two hoists 5, the puller on ...

Embodiment 2

[0050] Embodiment two, refer to figure 1 and figure 2 , a method for air treatment in implied meaning 1, comprising the following steps:

[0051] S1. Put the hoist 5 and the silt turning vehicle 4 into the hidden culvert 1, and set the two hoisting machines 5 at intervals, the silting turning vehicle 4 is between the two hoisting machines 5, and the drag cables 51 on the two hoisting machines 5 are connected with the two hoisting machines 5 respectively. The square frame 411 on the dump truck 4 is fixedly connected;

[0052] S2. Set two round hole-shaped ventilation holes at intervals on the top of the culvert 1, the upper port of the ventilation hole is connected with the outside world, and a blower 2 is installed in one ventilation hole, and an exhaust fan 3 is installed in the other ventilation hole. Make the air inside the culvert 1 form an outward-flowing airflow under the action of the blower 2 and the exhaust fan 3;

[0053] S3. Afterwards, the two winches 5 are sta...

Abstract

The invention relates to a system and method for air treatment in a buried culvert. The system comprises an air feeder and an exhaust fan, wherein the air feeder and the exhaust fan are arranged at the top positions of the buried culvert, and the air feeder and the exhaust fan are arranged in a spaced manner and communicate with the outside world separately. The system further comprises a silt turning trolley used for turning over the silt layer and two winches used for driving the silt turning trolley to move in the buried culvert, and the two winches are located on the two sides of the siltturning trolley separately. The system and method can reduce the content of poisonous gas in the silt layer before desilting work is carried out, thus reducing the risk of the desilting work.

Description

technical field [0001] The present invention relates to the technical field of air treatment, in particular to a system and method for air treatment in an undercover. Background technique [0002] Hidden culverts are culverts with a soil depth greater than 50 cm. Generally, there are round pipe culverts, stone arch culverts, box culverts, etc. The main function of hidden culverts is to drain water, and the water flowing through hidden culverts generally contains many impurities. Yes, it is easy to form a silt layer at the bottom of the culvert, so in order to maintain a good drainage effect of the culvert, it is generally necessary to regularly clean the silt layer inside the culvert. [0003] However, because the silt layer has been fermented for a long time, it generally contains a lot of toxic gases, such as hydrogen sulfide, ammonia and methane, so the dredging workers first need to separate a certain distance from the top of the culvert before dredging. Set exhaust fan...
