Description

A prefabricated protective device and layout method for intercepting pollution from benzene series chemicals

technical field

The invention relates to the field of river course interception, in particular to an assembled protective device and a layout method for intercepting pollution from benzene series chemicals.

Background technique

Chemicals are pure substances and mixtures of various elements, whether natural or man-made. For example, benzene series chemicals, which are an organic compound and the simplest aromatic hydrocarbon with a chemical formula of C ₆ H ₆ , are colorless and transparent liquids with carcinogenic toxicity and a strong aromatic smell. It is slightly soluble in water and easily soluble in organic solvents. There are many kinds of benzene series chemicals, such as benzene and toluene, both of which are hydrocarbons, and their density is lower than that of water.

The situation of water pollution is urgent, and one of the emergencies that cause river water pollution is the leakage of chemical transport ships in sensitive water body road sections. In order to adapt to such emergencies, the large logarithm adopts emergency measures to first intercept the river water upstream of the accident point, and then isolate the polluted river section to prevent the river water from spreading and polluting to prevent greater losses.

In the prior art, for example, in the "Treatment and Disposal Methods for Leakage of Benzene Substances" released on July 1, 2020, it is recorded that the treatment method for benzene-based chemicals is that when benzene-based substances with a density lower than water leak, when the leakage Use absorbent materials to collect spills when they are small, and use anti-dry skimmers or anti-suction pumps to transfer spills when they are large.

However, in the patent document whose application number is CN201910413833.3, it discloses a prefabricated river chemical emergency treatment system. The mortise structure is connected into the top beam of the dam, and the gaps are blocked and fixed by sandbags. The sandbags contain adsorbents. This design is easy to use, and it is convenient to absorb and recycle the leaked chemicals. Hazardous chemicals leak into sensitive water bodies, causing pollution and damage to water bodies and the environment. Regardless of whether the pollutants are floating pollutants, soluble pollutants, or insoluble pollutants that can sink to the bottom of the water, the interception dam body of this structure can perform filtration, adsorption and recovery according to its unique structure.

However, the above method has limitations when encountering flowing water with a faster flow rate, because when the benzene-based chemicals leak to the water surface, due to the faster flow speed of the flowing water, the benzene-based chemicals on the water surface will also flow quickly when they are pulled by the flowing water. As a result, when the chemicals are subsequently intercepted, it is easy to happen that the interception point has not been completed yet, and a large amount of chemicals are taken away by the rapid flow of water, that is, due to the high flow rate of the water, the driving force on the chemicals is also large, resulting in The interception point has low interception efficiency.

The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

As shown in Figures 1 to 8, the present invention provides an embodiment of a prefabricated protective device and a layout method for intercepting pollution from benzene series chemicals.

Specifically, the prefabricated protective device for intercepting pollution from benzene series chemicals is suitable for building river dams upstream to guide clean water to bypass pollutants, including

Multiple pairs of energy-dissipating rods 1, all of which are fixed in the river channel by objects preset at the bottom of the river and used as counterweights, and the plane of the central axis of each pair of energy-dissipating rods 1 is parallel to the water flow flow direction;

At least two partition strips 2, each partition strip 2 is connected with each pair of energy dissipation rods 1 in one-to-one correspondence, the partition strips 2 can separate the water flow in the river channel to form a plurality of energy dissipation channels 4;

Wherein, both ends of each energy dissipation flow channel 4 are provided with energy dissipation baffles 3, and the energy dissipation baffles 3 are suspended in the flowing water of the river channel and limit the velocity of the flowing water flowing into the energy dissipation flow channel 4;

Each energy dissipation flow channel 4 is provided with an interception frame 5, the surface of the interception frame 5 is provided with a converging surface for converging pollutants entering the energy dissipation flow channel 4, and the interception frame 5 is provided with an underwater part and a water surface part, intercepting The water surface portion of the frame 5 is provided with an intercepting head 6, which can collect pollutants floating on the water surface;

When the energy-dissipating baffle 3 limits the speed of the water entering the energy-dissipating flow channel 4 , the converging surface gathers the pollutants entering the energy-dissipating flow channel 4 and collects them through the intercepting head 6 .

The present invention can realize the separation of the water flow of the river through the multiple cooperation of the separation bag strip 2, the energy dissipation baffle 3 and the interception frame 5, and improve the interception efficiency of pollutants by reducing the flow velocity of the water after the separation. The bladder strip 2 separates the water flow to form a plurality of energy dissipation channels 4, so that the large stream of water flow is divided into multiple small streams of water flow, and then through the energy dissipation baffle 3, the small water flow entering the energy dissipation flow channel 4 is eliminated. The speed limit operation of the water flow prevents the water flow from quickly taking away the pollutants, and while the flow speed is limited, the pollutants entering the energy dissipation flow channel 4 can also be collected through the converging surface of the interception frame 5 and carried out through the interception head 6. charged so that pollutants are intercepted more efficiently.

It can be seen from the whole of the present invention that when intercepting pollutants, the flow is diverted first to reduce the impact force of large streams of water to prevent the interception frame 5 from being washed away, and then flow into the energy dissipation channel 4 from the water through the energy dissipation baffle 3 The speed of the water flow is limited so that the pollutants can flow normally, but the flow velocity of the water flow entering the energy dissipation channel 4 is slowed down, so that the water flow velocity impacting on the intercepting frame 5 is further removed, and the intercepting head 6 absorbs the pollutants There will be no situation where the suction speed cannot keep up with the water flow rate.

Specifically, the length of the energy-dissipating baffle 3 in the present invention is at least 1/2 of the length of the intercepting frame 5, so that the velocity of the water flow impacting on the converging surface is relatively low.

In the present invention, the structure of the energy-dissipating baffle 3 can refer to FIG. 2 , which can be made of rubber material, and the whole is soft and rectangular. At the same time, the distance between the position and the water surface should be at least 4 cm.

The assembling method of the separation bag strip 2 should be fast and convenient. Therefore, a pair of insertion holes 7 are provided on the separation bag strip 2, and each insertion hole 7 corresponds to each energy-dissipating rod 1 respectively, and the separation bag strip 2 can be installed inside Fix it on a pair of energy-dissipating rods 1 after filling with fluid;

The side wall of the energy-dissipating rod 1 is provided with a step for limiting the separation of the bag bar 2 .

After all the energy-dissipating rods 1 are fixed in the river channel by the items preset at the river bottom and used for counterweight, the two insertion holes 7 separating the bladder strips 2 are respectively one-to-one corresponding to the two energy-dissipating rods 1 Socketing, to realize the initial fixation of the partition strip 2, and then inject fluid (gas or liquid) into the partition strip 2, so that the partition strip 2 expands, to be expanded to the position shown in Figure 1 or Figure 3 and Figure 4 At this time, the inner wall of the insertion hole 7 is close to the side wall of the energy-dissipating rod 1, which can prevent the separation of the separation bag 2 from falling off. Limiting, and in order to prevent sliding on the separation bag bar 2, it can be bound by ropes.

In order to enable the intercepting head 6 to fully collect the pollutants gathered on the converging surface, so that the interception efficiency of the pollutants is high, it is preferred that the intercepting head 6 is arranged at the center of the converging surface of the intercepting frame 5 along the water flow direction area, the bottom edge sidewall of the intercepting head 6 is provided with an entry square hole 8, and the intercepting head 6 is provided with a liquid suction head that can float on the water surface and suck liquid, and the liquid suction head includes a counterweight that is slidably connected in the interception head 6 Section 9 and suction section 10, suction section 10 is arranged on the top of counterweight section 9, and counterweight section 9 can take suction section 10 to sink along intercepting head 6 inner wall until the working head on the suction section 10 is flush with the water surface.

Specifically, the converging surface in the present invention is preferably arc-shaped, and may also be in other shapes, as long as the purpose of converging the pollutants entering the energy-dissipating flow channel 4 is satisfied.

After the partition strip 2 is installed, the interception frame 5 and the energy dissipation baffle 3 can be fixed by ropes (the partition strip 2, the interception frame 5 and the energy dissipation baffle 3 are provided with hooks for fixing the ropes) , the final fixed state can refer to Figure 1 and Figure 2.

After the installation of all components is completed, the water flow flowing along the river will be separated by the partition strip 2 to form multiple energy dissipation flow channels 4, so that the large water flow is divided into multiple small water flows, and then passed through the energy dissipation channel 4. The energy baffle plate 3 performs a speed-limiting operation on the small stream of water entering the energy dissipation channel 4 from the water flow to prevent the water flow from quickly taking away pollutants, and then the pollutants on the water surface flow to the intercepting frame 5 along with the water flow.

At this time, the water flow floats the counterweight section 9, so that the working head on the suction section 10 is flush with the water surface, and then, start the vacuum pump and other pumping devices, and the pollutants on the water surface will enter the working head on the suction section 10 through the square hole 8 , and then drawn into the vacuum pump through the hose.

In the present invention, arranging the liquid suction head in the intercepting head 6 can limit the position of the liquid suction head, prevent the liquid suction head from shaking randomly, and at the same time prevent debris from blocking the liquid suction head.

In order to realize the collection operation of pollutants, therefore, an embodiment is provided for the intercepting frame 5, so that all the intercepted pollutants will not accumulate in the area where the converging surface is located.

The intercepting frame 5 includes a frame body 11 floating on the water surface. The frame body 11 is located in the energy dissipation flow channel 4. The converging surface is arranged on the side of the frame body 11 facing the flow direction of the water flow. There is a liquid storage bag 12, the liquid storage bag 12 can receive the liquid sucked by the pipette head, the bottom of the frame body 11 is provided with a sealing plate 13 fixedly connected with the liquid storage bag 12, the sealing plate 13 is located in the underwater part and can be pushed The liquid storage bag 12 enters the containing cavity, and the top of the frame body 11 is provided with an insulating plate 30 .

After the pollutants are sucked into the vacuum pump and other devices, they can be directly passed into the accommodation chamber through the hose. Afterwards, as the pollutants entering the accommodation chamber increase, the sealing plate 13 will sink into the water, and during the sinking process of the sealing plate 13 During the process, the liquid storage bag 12 will be straightened gradually (the liquid storage bag 12 is placed in the holding chamber before being straightened), so that the holding chamber can store more pollutants.

In this embodiment, air vents can be provided on the insulating plate 30, so that the vacuum pump and other devices will not expand the containing chamber when evacuating. Contaminants can be pumped all the way to the shore to prevent tipping of the reservoir bladder 12 when it fills up.

In order to prevent the sinking sealing plate 13 from being tilted by the water flow, it is preferred that the side wall of the frame body 11 is provided with a limiting head 14; the side wall of the sealing plate 13 is connected with a limiting rod 15 through a rotating shaft at the position corresponding to the limiting head 14, The restricting rod 15 can be limited by the restricting head 14 , and a slide groove 16 is opened on the surface of the restricting rod 15 corresponding to the restricting head 14 .

Referring to Fig. 8, the sealing plate 13 fixes one end of the limiting rod 15 through the rotating shaft, so when the sealing plate 13 sinks, the sealing plate 13 will slide down together with the limiting rod 15, and when the limiting rod 15 slides, due to the restriction head 14 and the sliding groove 16 cooperate, so the limiting rod 15 can only slide along the side wall of the frame body 11, so that the sealing plate 13 can only vertically descend, and there will be no phenomenon that the sealing plate 13 is driven by the water flow to tilt.

In order to realize the collection operation of pollutants, on the basis of the above-mentioned embodiments, a second embodiment is provided for the interceptor frame 5:

In order to intercept pollutants at the edge of the river, it is preferred that the intercepting frame 5 also includes an arresting frame 17 that is arranged on the frame body 11 away from the end of the partition bag bar 2. The blocking frame 17 is provided with a movable chamber 18, and the blocking frame 17 and the frame The body 11 is detachably connected; the blocking frame 17 includes a fixed section 19 and a flexible section 20 that are fixedly connected. When the blocking frame 17 is connected to the intercepting frame 5, the flexible section 20 fits with the end of the frame body 11 through deformation to guide the blocking frame 17 The water-facing surface is flush with the converging surface.

In the second embodiment, the blocking frame 17 provided can be used independently or in conjunction with the frame body 11 in the first embodiment. When used independently, it is suitable for a smaller area. When used with the frame body 11 in the first embodiment, it is equivalent to The width of the entire converging surface is lengthened, so that the converging surface can collect a wider range of pollutants, which can be used in areas near the shore.

The following will be described in conjunction with the use of the frame body 11 in Embodiment 1:

Before use, the blocking frame 17 and the frame body 11 need to be installed, that is, when the blocking frame 17 is connected to the frame body 11, the flexible section 20 is pushed to be close to the frame body 11. Fit the upper part to guide the blocking frame 17 to be flush with the converging surface, and then connect the frame body 11 to the fixed section 19 with bolts on the back of the frame body 11 through the fixing plate, that is, the assembly of the blocking frame 17 and the frame body 11 is completed .

In order to prevent the flexible section 20 from being pushed and deformed by the water flow, it is preferable that a guide rail bar 21 is installed on the inner wall of the movable chamber 18 and the corresponding area of the fixed section 19, and a push block 22 is slidably connected to the guide rail bar 21, and the push block 22 is close to One end sidewall of the flexible section 20 is equipped with a pair of shaping pieces 23, and when the flexible section 20 fits with the end of the frame body 11 through deformation, the pair of shaping pieces 23 presses against the inner wall of the flexible section 20 to force the flexible section 20 to contact the intercepting frame. 5. The ends are tightly fitted; one end of the top of the blocking frame 17 is provided with a stepped plate 24 fixedly connected to the fixed section 19, and the surface of the stepped plate 24 is provided with an arc-through groove 25, and the arc-through groove 25 is slidingly provided with a push block 22 The push column 26 that is fixedly connected.

After completing the assembly of the blocking frame 17 and the frame body 11, due to the existence of the flexible section 20, the flexible section 20 is easily bent and deformed when the water flow impacts, so the push column 26 can be directly pushed to make it move along the inner wall of the arc slot 25. After sliding, the sliding push post 26 will slide along the guide rail bar 21 with the push block 22, and the sliding push block 22 will simultaneously push the two shaping pieces 23 to press on the inner wall of the flexible section 20 to force the flexible section 20 to intercept The ends of the frame 5 are closely fitted (that is, the flexible section 20 is shaped, refer to FIG. 7 for details), and then the nuts and other components are pressed against the surface of the step plate 24 to limit the position of the push column 26 .

In this embodiment, the flexible section 20 can be a pouch made of rubber.

In order to increase the amount of pollutants absorbed so that the pollutants will not slip away from the edge of the converging surface, it is preferable that the side wall of the insulating plate 30 is provided with an accommodation groove 27, and an elastic rod 28 is installed in the accommodation groove 27 to absorb the pollutants. The side wall of the liquid head is equipped with a liquid suction pipe 29 that passes through the square hole 8 and is connected with the elastic rod 28. The liquid suction pipe 29 can introduce water surface pollutants into the liquid suction head. When the suction section 10 is not floated by the water surface, The counterweight section 9 pulls the suction section 10 down and pulls the elastic rod 28 to bend and deform; direction movement.

When there is no pollutant in the accommodation cavity, the suction section 10 is not floated by the water surface at this time, so the counterweight section 9 will pull the suction section 10 down and pull the elastic rod 28 to bend and deform;

As the pollutants continue to enter the accommodation chamber, the frame body 11 will gradually be driven underwater, and when the frame body 11 sinks toward the water, due to the buoyancy of the suction section 10, the suction section 10 will be under the action of water. It rises downward, that is, the suction section 10 is floated by the water surface, and then the suction pipe 29 is driven up by the suction section 10, so that the degree of bending deformation of the elastic rod 28 is reduced, that is to say, the elastic rod 28 will reset and force the suction pipe. 29 moves in a direction away from the insulation panel 30.

In general, the suction section 10 descends and pulls one end of the suction pipe 29 to drop, so that the elastic rod 28 bends, and the suction section 10 rises so that the end of the liquid suction pipe 29 also rises, the bending degree of the elastic rod 28 decreases, and the elastic rod 28 bends. 28 straightening, will move toward the direction away from insulation plate 30 with suction pipe 29, can install suction head on this liquid suction pipe 29, and can install air bag on this water suction head, make this water suction head float on the water surface all the time, Once the suction pipe 29 absorbs water, the water can be sent into the suction section 10 by the water suction head, and then sent into the accommodating chamber by the suction section 10 (the water suction head is used in conjunction with the working head on the suction section 10). 29 moves away from the insulation board 30, the water suction head will also move away from the insulation board 30, that is, the scope of the water suction head to absorb liquid increases. (The water suction head is not shown in the figure, and the conventional setting means in the prior art can be selected, as long as the purpose of the water suction head floating on the water surface and being able to absorb the liquid on the water surface is satisfied).

In the present invention, components with greater buoyancy should be arranged on the frame body 11, such as airbags or floating bodies similar to those used in oil booms.

The present invention is in use (adopting the mode explanation of embodiment two to cooperate embodiment one):

All the energy-dissipating rods 1 are fixed in the river channel through the items preset at the river bottom and used for counterweight, and then the two insertion holes 7 separating the bladder strips 2 are respectively set one-to-one with the two energy-dissipating rods 1 connected to realize the initial fixation of the partition strip 2, and then inject fluid (gas or liquid) into the partition strip 2, so that the partition strip 2 expands to be expanded as shown in Fig. 1 or Fig. 3 and Fig. 4 The state is enough, and now the inner wall of the insertion hole 7 is close to the side wall of the energy-dissipating rod 1, which can prevent the separating bag strip 2 from detaching.

Then according to the width of the river channel, the blocking frame 17 is installed on some frame bodies 11 to increase the length of the converging surface. Specifically, when the blocking frame 17 is connected with the frame body 11, the flexible section 20 is pushed to be close to the frame body 11. The flexible section 20 fits the end of the frame body 11 through deformation to guide the water-facing surface of the blocking frame 17 to be flush with the converging surface, and then pushes the push column 26 to slide along the inner wall of the arc slot 25. After that, the sliding push The column 26 will slide along the guide rail bar 21 with the push block 22, and the sliding push block 22 will simultaneously push the two shaping pieces 23 to press against the inner wall of the flexible section 20 to force the flexible section 20 to closely fit the end of the intercepting frame 5 (That is to shape the flexible section 20, see Figure 7 for details), then press the nuts and other parts on the surface of the step plate 24 to limit the position of the push column 26, and finally pass the fixing plate on the back of the frame body 11. The frame body 11 is fixedly connected with the fixing section 19 , that is, the assembly of the blocking frame 17 and the frame body 11 is completed.

After the partition strip 2 is installed, the intercepting frame 5 and the energy dissipation baffle 3 can be fixed by ropes, and the final fixed state can refer to Fig. 1 and Fig. 2 .

After the installation of all components is completed, the water flow flowing along the river will be separated by the partition strip 2 to form multiple energy dissipation flow channels 4, so that the large water flow is divided into multiple small water flows, and then passed through the energy dissipation channel 4. The energy baffle plate 3 performs a speed-limiting operation on the small stream of water entering the energy dissipation channel 4 from the water flow to prevent the water flow from quickly taking away pollutants, and then the pollutants on the water surface flow to the intercepting frame 5 along with the water flow.

At this time, the water flow floats the counterweight section 9, so that the working head on the suction section 10 is flush with the water surface, and then, start the vacuum pump and other pumping devices, and the pollutants on the water surface will enter the working head on the suction section 10 through the square hole 8 , and then drawn into the vacuum pump through the hose.

After the pollutants are sucked into devices such as vacuum pumps, they can be directly passed into the holding chamber through the hose. Afterwards, as the pollutants entering the holding chamber increase, the sealing plate 13 will sink into the water, and the sealing plate 13 will sink into the water.
