Description

Technical Field

[0001] The utility model relates to the technical field of aeration treatment devices, in particular to an aeration treatment device for in-situ soil washing liquid. Background Art

[0002] Soil contaminated with volatile organic compounds may need to be treated through in-situ leaching. By injecting leaching fluid into the injection well, the leached groundwater is extracted in the extraction well and sent to the ground treatment system for treatment. After the treatment is completed, an aeration treatment device is required to perform gas-liquid separation on the extracted leached groundwater through aeration.

[0003] In the prior art, when aeration is performed on the extracted groundwater, it is usually necessary to inhale external air through an aeration pipe, use a tower-type gas-liquid separation device to perform gas-liquid separation, and then treat the waste gas through a waste gas treatment device. However, in actual use, the waste gas treatment device needs to replace its filter element after long-term use. When replacing the filter element, it is often necessary to shut down the device for treatment, otherwise it will cause waste gas to overflow, which will cause the gas-liquid separation process to be suspended, affecting the treatment efficiency. Therefore, it is necessary to improve an aeration treatment device for in-situ soil washing liquid to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide an in-situ soil washing liquid aeration treatment device to solve the problems raised in the above background technology.

A baffle shaft is fixedly installed on the back of the drive shaft of the motor to facilitate the zoning treatment of waste gas through the anti-shutdown waste gas treatment mechanism.

[0010] Preferably, holes are provided at corresponding positions of the partition cross plate and the shielding plate shaft, and the shielding plate shaft is rotatably installed inside the hole provided inside the partition cross plate, so as to normally shield the air intake pipe.

[0013] Compared with the prior art, the present invention provides an in-situ soil washing liquid aeration treatment device, which has the following beneficial effects:

[0014] 1. The in-situ soil washing liquid aeration treatment device is provided with an anti-shutdown exhaust gas treatment mechanism. During use, after the exhaust gas enters the interior of the exhaust gas treatment box, it will pass through the air inlet pipe and can enter the interior of the exhaust gas filter element body in four different areas. The partitions set by the partition cross plate are used to prevent the four areas from interfering with each other. The different air inlet pipes are blocked by the rotation of the shielding plate shaft, so that the area will not be exposed to exhaust gas and the exhaust gas will be discharged from other areas. The corresponding exhaust gas filter element body can be replaced without stopping the machine, thereby avoiding affecting the efficiency of gas-liquid separation.

The liquid enters from the bottom and is discharged from the top, and is discharged into the clean water tank through the pipe. The gas can be discharged into the exhaust gas treatment box through the exhaust pipe. The baffle can be used to enhance the disturbance of the liquid and the gas-liquid separation effect, thereby realizing the function of aeration treatment of the in-situ soil washing liquid.

[0027] The anti-shutdown waste gas treatment mechanism 3 includes a partition partition component 31 and a removable filter element component 32, and the removable filter element component 32 is arranged inside the partition partition component 31.

[0028] Furthermore, the partition partition component 31 includes a waste gas treatment box 311, the waste gas treatment box 311 is fixedly installed at one end of the exhaust pipe 25 away from the jet aeration tower 21, an observation glass 312 is arranged on the back of the waste gas treatment box 311, a partition board 313 and a partition cross plate 314 are fixedly installed inside the waste gas treatment box 311, an intake pipe 315 is fixedly installed on the back of the partition board 313, an exhaust pipe 316 and a motor 317 are fixedly installed on the front of the waste gas treatment box 311, and a baffle plate shaft 318 is fixedly installed on the back of the transmission shaft of the motor 317, which is convenient for the waste gas to be partitioned and treated through the anti-shutdown waste gas treatment mechanism 3.

[0029] Furthermore, holes are opened at the corresponding positions of the partition cross plate 314 and the baffle plate shaft 318, and the baffle plate shaft 318 is rotatably installed inside the holes opened in the partition cross plate 314, which is convenient for normally blocking the intake pipe 315.

[0030] Furthermore, the filter element installation assembly 32 includes a threaded inner seat 321, which is fixedly installed on the front of the partition plate 313. The internal thread of the threaded inner seat 321 is installed with a docking threaded tube 322, and the front of the docking threaded tube 322 is fixedly installed with an exhaust gas filter element body 323.

[0031] Furthermore, four external mounting threaded tubes 325 are provided, and the backs of the four external mounting threaded tubes 325 are fixedly mounted to the front of the exhaust gas treatment box 311, so as to facilitate partitioned disassembly under normal conditions.

[0032] Embodiment 2:

[0033] See also Figure 5 , and combined with Example 1, it is further obtained that the gas-liquid separation mechanism 2 includes a jet aeration tower 21, the jet aeration tower 21 is fixedly installed on the right side of the water pipe 1, a baffle 22 is fixedly installed inside the jet aeration tower 21, a pipeline 23 is provided on the right side of the jet aeration tower 21, a clear water tank 24 is provided at one end of the pipeline 23 away from the jet aeration tower 21, and an exhaust pipe 25 is provided on the top of the jet aeration tower 21 to facilitate gas-liquid separation of the groundwater after elution by the gas-liquid separation mechanism 2.
