Description

Technical Field

[0001] The present invention relates to the technical field of groundwater collection, and particularly to a device for collecting waste liquid and waste gas of groundwater. Background Art

[0002] Groundwater is stored in the subsurface voids below the vadose zone, including rock pores, fractures, and karst caves. Groundwater is one of the most important and widely distributed water resources on the earth. It is necessary to sample and monitor the water quality of groundwater to understand the pollution distribution and types, which is beneficial to the treatment of groundwater.

[0003] In existing collection devices, especially in the sampling of waste gas, most store the waste gas in the form of gas, using the method of storing gas bags. There are not only problems of air leakage, but also large space occupation and difficult transportation. Summary of the Invention

[0004] To solve the above problems, the present invention discloses a device for collecting waste liquid and waste gas of groundwater, including a housing. The interior of the housing is divided into upper and lower layers, and a water storage tank is arranged in the lower layer. A water pump is arranged obliquely above the water storage tank, and the output end of the water pump is communicated with the water storage tank. The input end of the water pump is fixedly connected with a water suction pipe. When the water pump works, water is pumped into the water storage tank.

[0005] An electric heating structure is arranged inside the water storage tank. An adsorber is arranged in the middle of the upper layer of the housing. The adsorber is composed of multiple pipe fittings with adsorption fillers arranged side by side. Both the upper and lower parts of the adsorber are provided with matching blocks, and the matching block located below is fixedly connected to the housing. Channels are arranged on the matching blocks to realize the series connection and communication of the pipe fittings. A negative pressure pump is arranged below the adsorber. The output end of the negative pressure pump is fixedly connected with an air delivery pipe, and the other end of the air delivery pipe is connected to the matching block located below. The input end of the negative pressure pump is fixedly connected with an air suction pipe, and the other end of the air suction pipe is fixedly connected to the upper part of the water storage tank. The water in the water storage tank is heated, and the negative pressure pump works to form a negative pressure in the water storage tank, so as to desorb the waste gas or organic waste gas pollutants in the groundwater, and then send the desorbed organic matter into the adsorber, where it is absorbed by the resin or activated carbon therein. Using this method can avoid using gas storage containers. Relatively speaking, the volume used for sample storage is smaller.

[0006] Furthermore, since the cost of waste gas pollution in groundwater is unknown, the adsorber adopts multiple pipe fittings, and different resins with different characteristics are filled in the pipe fittings to adsorb and store different types of organic pollutants.

[0007] Preferably, a first drawer is provided at the upper part of the front surface of the housing, and the negative pressure pump is located behind the first drawer. Electrical chambers and battery compartments are respectively provided on both sides of the upper layer of the housing. The first drawer is used to store the related appliances for collection, while the electrical chamber is for placing electronic components such as circuit boards.

[0008] Preferably, a storage chamber is provided in the lower layer of the housing. A second drawer is provided in the middle of the storage chamber, and a sleeve is provided outside the second drawer. The storage chamber is used to store the water suction pipe, and the water suction pipe is wound around the sleeve. The second drawer has the same function as the first drawer and is used to store appliances.

[0009] Preferably, a drain pipe is fixedly connected to one side of the water tank, and a water valve is provided on the drain pipe. When the water pump works, the water valve is opened in advance to drain the groundwater pumped horizontally. After stabilization, the water valve is closed. Similarly, when it is necessary to store water samples, the water valve can be opened to introduce the water into a storage container. The container can be stored in the first drawer or the second drawer.

[0010] Preferably, a groove is provided at the upper end of the housing, and the mating block located above is located in the groove. A cover plate is provided to cover the upper part of the groove. Bolts are inserted through both sides of the cover plate, and the bolts are threadedly connected to the housing. By loosening the bolts and removing the cover plate, the mating block located above can be removed, and then the adsorber can be taken out or put in.

[0011] Preferably, feet are fixedly connected to the four corners of the lower end of the housing, and a handle is fixedly connected to the upper end of the housing. The feet and the handle facilitate the use of the device.

[0012] Preferably, a zeolite counterweight is fixedly connected to one end of the water suction pipe, and a float and a tight hoop are provided on the water suction pipe. The zeolite counterweight ensures the vertical state of the water suction pipe and can also provide a filtering function. The tight hoop is clamped on the water suction pipe, and the position of the tight hoop can be set on the water suction pipe. The float is sleeved on the water suction pipe, and the tight hoop cannot pass through the float. Therefore, under this setting, by setting the position of the tight hoop, the pumping work of different water layers can be realized.

[0027] The present invention will be further illustrated below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and not to limit the scope of the present invention. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the accompanying drawings, and the terms "inner" and "outer" refer to the directions towards or away from the geometric center of a specific component, respectively. Embodiment 1

[0028] As Figures 1 to 4 shown, a waste liquid and waste gas collection device for groundwater includes a housing 1. The overall structure of the housing 1 is a cuboid. The interior of the housing 1 is divided into upper and lower layers. A partition is provided in the middle, and a water sump 17 is provided in the lower layer for temporarily storing groundwater and separating the waste gas in the groundwater or the organic waste gas pollutants adsorbed therein. An inclined upper part of the water sump 17 is provided with a water pump 15, and the output end of the water pump 15 is communicated with the water sump 17. The input end of the water pump 15 is fixedly connected with a water suction pipe 14. When the water pump 15 works, groundwater is pumped into the water sump 17 through the water suction pipe 14.

[0029] An electric heating structure is provided inside the water sump 17. The electric heating structure is an element that generates heat when electrified, such as an electric heating wire or an electric heating plate. Its purpose is to heat the groundwater to separate the organic substances in the groundwater. In the middle of the upper layer of the housing 1, an adsorber 20 is provided. The adsorber 20 adsorbs and stores the organic pollutants separated from the groundwater by wind force. The adsorber 20 is formed by arranging a plurality of pipe fittings with adsorption fillers inside side by side. Here, the adsorption filler is resin or activated carbon. Since the types of organic pollutants are different and their physical and chemical properties exist, if only one kind of adsorption filler is used, not all organic pollutants can be adsorbed and stored as much as possible. Both the upper and lower parts of the adsorber 20 are provided with mating blocks 19, and the mating block 19 located below is fixedly connected to the housing 1. The mating block 19 is provided with a channel to realize the series connection and communication of the pipe fittings. A negative pressure pump 13 is provided below the adsorber 20. The output end of the negative pressure pump 13 is fixedly connected with an air delivery pipe 12, and the other end of the air delivery pipe 12 is connected to the mating block 19 located below. The input end of the negative pressure pump 13 is fixedly connected with an air suction pipe 16, and the other end of the air suction pipe 16 is fixedly connected to the upper part of the water sump 17.

[0030] When the negative pressure pump 13 works, a negative pressure is generated in the water sump 17. In combination with the electric heating structure, the desorption of the organic pollutants in the groundwater is promoted, and under the suction of the negative pressure pump 13, the organic pollutants are introduced into the adsorber 20 for adsorption and storage treatment. After the collection at the current collection point is completed, the adsorber 20 is taken out of the housing 1, and the upper and lower ends of the adsorber 20 are covered with a sealing cover 21.

[0031] At the upper part of the front of the housing 1, a first drawer 2 is provided. The first drawer 2 is used to store the chamber adsorber 20 or a container for storing water samples. And the negative pressure pump 13 is located behind the first drawer 2. On both sides of the upper layer of the housing 1, an electrical chamber 10 and a battery compartment 11 are respectively provided. The electrical chamber 10 is used to place electronic components such as circuit boards for the control of the device, and the battery compartment 11 is for storing the storage battery, which is used for the power supply of the device.

[0032] At the lower layer of the housing 1, a storage chamber 8 is provided. The storage chamber 8 is for storing the water extraction pipe 14. In the middle of the storage chamber 8, a second drawer 9 is provided. The second drawer 9 has the same function as the first drawer 2. And a sleeve is provided on the outside of the second drawer 9. The sleeve is used to support and seal the second drawer 9. And with the use of the sleeve, the water extraction pipe 14 is wound on it, which is conducive to storage and arrangement.

[0033] One side of the water tank 17 is fixedly connected with a drain pipe 7, and a water valve 6 is provided on the drain pipe 7. When the water pump 15 works, groundwater is pumped into the water tank 17 through the water extraction pipe 14. At the same time, the water valve 6 is opened to discharge the extracted groundwater. After stable operation, the water valve 6 is closed. When there is a need to store water samples, the groundwater is introduced into the storage container through the drain pipe 7. When adsorption treatment is required, the water valve 6 needs to be closed.

[0034] At the upper end of the housing 1, a groove is provided, and the upper mating block 19 is located in the groove. Concave structures are provided on both sides of the upper mating block 19, which is convenient for pinching and taking out the mating block 19. Below it is the adsorber 20. A cover plate 5 is provided to cover the upper part of the groove. Removing the cover plate 5 exposes the upper mating block 19. Bolts 4 are inserted through both sides of the cover plate 5, and the bolts 4 are threadedly connected with the housing 1. The bolts 4 are used for fixing the cover plate 5.

[0035] At the four corners of the lower end of the housing 1, feet 18 are fixedly connected, which is convenient for placing the device. At the upper end of the housing 1, a handle 3 is fixedly connected, which is conducive to lifting and transferring the device. Embodiment 2

[0036] Based on Embodiment 1, as Figure 5 shown, the following structure is added in this example. One end of the water extraction pipe 14 is fixedly connected with a zeolite counterweight 22, and the zeolite counterweight 22 has the ability to filter. A float 23 and a tight hoop 24 are provided on the water extraction pipe 14.

[0037] It should be noted here that this embodiment is used for underground pumping or extraction of surface water underground. The tightening hoop 24 is provided to be adjustable in position on the water extraction pipe 14. The float 23 is sleeved on the water extraction pipe 14. At the same time, the float 23 is located between the zeolite counterweight 22 and the tightening hoop 24, and the float 23 cannot pass through the tightening hoop 24. This setting is that after the position of the tightening hoop 24 is set, the zeolite counterweight 22 is put into the water, and under the action of the zeolite counterweight 22, the water extraction pipe 14 maintains a vertical state. And under the block of the tightening hoop 24, the zeolite counterweight 22 can only reach the specified water depth. Therefore, water samples at a specified depth can be obtained in this way. Embodiment 3

[0038] Based on Embodiment 1, as Figure 6 shown, this example adds the following structure: The end of the water extraction pipe 14 is fixedly connected with an insertion rod 27 for inserting the insertion rod 27 into the ground. A limiting pedal 26 is fixedly connected to the insertion rod 27, and the position of the limiting pedal 26 can be adjusted on the insertion rod 27. The lower end of the insertion rod 27 is sharpened to facilitate the insertion of the insertion rod 27 into the ground, and a water inlet hole 25 is provided on the side wall near the end for water inlet. The internal filtering structure of the insertion rod 27 is realizing filtration.

[0039] It should be noted here that this example is used for the extraction operation of shallow underground water. The provided limiting pedal 26 facilitates the driving of the insertion rod 27 into the ground. At the same time, the position of the limiting pedal 26 is adjustable. Under the block of the limiting pedal 26, the insertion rod 27 inserted into the ground can be controlled, which is beneficial to the extraction of groundwater at different depths.
