Description

Technical Field

[0001] This utility model relates to the field of CNG tube bundle vehicle sewage recycling technology, specifically a safe and environmentally friendly tube bundle vehicle sewage discharge device. Background Technology

[0002] Currently, compressed natural gas (CNG) transport vehicles, also known as tube-bundle vehicles, accumulate small amounts of oily wastewater and other fine impurities in their cylinders after a period of transport. If this is not discharged, it can cause ice blockage in the equipment and pipelines of the CNG substation, as well as damage to the equipment filters and check valves. This can lead to incomplete closure of the check valves, pressure buildup due to ice blockage, or even prevent the CNG substation from operating normally. Currently, most hazardous chemical transport companies discharge CNG tube-bundle vehicles arbitrarily and openly without any recovery devices or safety measures. The wastewater is directly discharged on-site after the tube-bundle vehicle's discharge valve is opened. This discharge poses a significant safety hazard. The large amount of natural gas discharged during the discharge can cause fires or even explosions if there is poor ventilation, open flames, or static electricity.

[0003] For CNG tube bundle vehicle wastewater discharge, although existing methods involve temporarily collecting oil sludge during discharge using a receiving box and releasing natural gas at high altitude via a vent pipe, followed by transferring the oil sludge to a hazardous waste disposal site for treatment, these methods have the following shortcomings: The direct and singular release of natural gas into the atmosphere inevitably leads to significant waste with repeated discharges; the lack of a mechanism for separate collection, return, and reuse of natural gas results in poor performance; and direct atmospheric discharge of large quantities at high concentrations poses certain safety hazards. Therefore, this application proposes a safe and environmentally friendly tube bundle vehicle wastewater discharge device to address these problems. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1 to 3 As shown in the figure, the safe and environmentally friendly tube bundle vehicle sewage discharge device proposed in this embodiment includes:

[0027] The sludge collection box 1 has a drain valve 101 fixedly connected to its bottom right side and a sludge inlet pipe 103 fixedly connected to its bottom left side. Its bottom inner wall is set as an inclined surface. Its top is fixedly installed with a cover plate 104 by four screws. Its bottom is fixedly connected with a base plate 105. The bottom of the base plate 105 is rectangular and has four lockable casters installed.

[0028] L-shaped vent pipe 102 is connected and fixed to the top right side of the sludge collection box 1, and an internally threaded pipe cap is screwed onto the outer side of its top end.

[0029] The air filter splash prevention assembly is installed inside the sludge collection box 1 and is in active contact with the bottom of the cover plate 104;

[0030] The natural gas extraction, collection, pressure discharge, and return assembly is installed on top of the cover plate 104 and connected to the inside of the sludge collection tank 1. Both the natural gas extraction, collection, pressure discharge, and return assembly and the sludge collection tank 1 have explosion-proof hoses 100 with threaded connectors at both ends on the left side. The sludge inlet pipe 103 is threadedly connected to the threaded connector at the bottom of the lower explosion-proof hose 100. The lower explosion-proof hose 100 is used to connect to the CNG pipeline vehicle's sludge discharge port, allowing oil to flow into the sludge collection tank 1 when the valve on the CNG pipeline vehicle's sludge discharge port is opened. The gas filter and splash shield assembly is used to shield against oil and filter out rising natural gas. Natural gas extraction... The collection and return assembly is used to extract and collect natural gas from oil spills, and to supply the collected natural gas by pressure discharge when the explosion-proof hose 100 above is connected to the CNG pipeline vehicle inlet or external natural gas storage tank, reducing the waste of natural gas by direct emission into the air; the L-shaped vent pipe 102 is used to connect to the external vent pipe to assist personnel in releasing the gas into a safe space more than three meters away from the ground when it is necessary to release the gas into the air; the sewage discharge valve 101 is installed so that after the sewage is collected on site, the personnel can transfer this device to the hazardous waste disposal site and then discharge the oil spill for hazardous waste disposal.

[0031] In this embodiment, a transparent observation plate 106 is embedded and fixed on the front right side of the sludge collection box 1, which facilitates personnel to directly observe the oil sludge collection status inside the sludge collection box 1; a pressure gauge 3 is fixedly installed on the top right side of the cover plate 104, and the detection end of the pressure gauge 3 extends into the sludge collection box 1. The pressure gauge 3 is used to detect and display the pressure inside the sludge collection box 1, so that personnel can judge the natural gas extraction status by judging its internal pressure; the top of the L-shaped vent pipe 102 has a first external thread that is threaded to connect with the internal threaded pipe cover, and a first sealing ring is bonded and fixed on the inner wall of the top of the internal threaded pipe cover, which is in tight contact with the top of the L-shaped vent pipe 102; the outside of the sludge inlet pipe 103 has a second external thread that is threaded to connect with the threaded connector at the bottom of the explosion-proof hose 100 below, and a second sealing ring is placed inside the threaded connector, and the sludge inlet pipe 103 is in tight contact with the corresponding second sealing ring.

[0032] Furthermore, such as Figure 3 As shown, the air filtration splash prevention assembly includes an annular limiting strip 4, a stainless steel filter screen cover 401, and an abutment block 402. The annular limiting strip 4 is fixedly connected inside the sludge collection box 1. The stainless steel filter screen cover 401 is movably fitted inside the sludge collection box 1 and makes movable contact with the top of the annular limiting strip 4. The abutment block 402 is fixedly connected to the top of the stainless steel filter screen cover 401, and the top of the abutment block 402 makes movable contact with the bottom of the cover plate 104.

[0033] In this implementation scheme, the annular limiting strip 4, the stainless steel filter screen cover 401, and the abutment block 402 work together to prevent oil from entering the sludge collection tank 1, which contains a large amount of natural gas. The stainless steel filter screen cover 401 blocks the oil from splashing upwards, and the gas rises and passes through the filter holes of the stainless steel filter screen cover 401, thus blocking the oil and filtering out the rising natural gas. After the cover plate 104 is removed by loosening the four screws with tools, the abutment block 402 can be pulled upwards to move the stainless steel filter screen cover 401 upwards for cleaning or replacement. This allows the stainless steel filter screen cover 401 to be easily removed and replaced after long-term use.

[0034] Furthermore, such as Figure 1 , 2 As shown in Figure 3, the natural gas extraction, collection, pressure discharge, and return assembly includes a gas storage tank 2, a piston plate 204, two T-shaped guide rods 205, a multi-stage electric telescopic rod 206, a one-way valve 201, an L-shaped pipe 202, a manual valve 203, and an externally threaded pipe head. The gas storage tank 2 is fixedly installed on the top of the cover plate 104. The one-way valve 201 is fixedly installed on the top of the cover plate 104 and communicates with the inside of the sludge collection tank 1. The top of the one-way valve 201 is the outlet and is fixedly connected to the bottom of the gas storage tank 2. The piston plate 204 is sealed and slidably sleeved inside the gas storage tank 2. The multi-stage electric telescopic rod 206 is fixedly installed on the gas storage tank 2. At the top of the gas tank 2, the extended end of the multi-stage electric telescopic rod 206 is fixedly connected to the top of the piston plate 204. Two T-shaped guide rods 205 are fixedly connected to the top of the piston plate 204. The gas tank 2 is slidably sleeved on the two T-shaped guide rods 205. A scale line is provided on the front side of the T-shaped guide rod 205 on the left side. The L-shaped tube 202 is connected and fixed to the bottom left side of the gas tank 2. The manual valve 203 is connected and fixed to the left end of the L-shaped tube 202. The external threaded pipe head is connected and fixed to the left end of the manual valve 203. The threaded connector at the bottom of the explosion-proof hose 100 above is threaded onto the external threaded pipe head.

[0035] In this embodiment, a lithium battery is fixedly installed on the top right side of the cover plate 104, and the multi-stage electric telescopic rod 206 is electrically connected to the lithium battery; a vent hole communicating with the interior of the top left side of the gas storage tank 2 is provided to prevent the piston plate 204 from being blocked and damped from the top when it moves; two vertical guide holes are provided on the top of the gas storage tank 2, which are respectively slidably fitted to the outer side of the corresponding T-shaped guide rod 205, so as to guide the vertical sliding of the T-shaped guide rod 205; three sealing rings are adhesively fitted on the outer side of the piston plate 204, which are in close sliding contact with the inner side of the gas storage tank 2, so as to achieve a sliding seal between the outer side of the piston plate 204 and the inner side of the gas storage tank 2; four support rods are fixedly connected in a rectangle between the bottom of the gas storage tank 2 and the top of the cover plate 104.

[0036] In this implementation plan, through the cooperation of the gas storage tank 2, piston plate 204, two T-shaped guide rods 205, multi-stage electric telescopic rod 206, one-way valve 201, L-shaped pipe 202, manual valve 203, and external threaded pipe head, when natural gas needs to be recovered and collected rather than directly released, during the sewage discharge process, personnel reverse-start the multi-stage electric telescopic rod 206 to drive the piston plate 204 to slide upwards within the gas storage tank 2. The piston plate 204 draws the natural gas floating in the sewage collection tank 1 into the gas storage tank 2 through the one-way valve 201. When the piston plate 204 moves upwards, it also drives the two T-shaped guide rods 205 to move upwards. After connecting the explosion-proof hose 100 above to the CNG pipe bundle vehicle inlet or external natural gas storage tank, personnel judge the degree of upward movement of the piston plate 204 by the scale line on the left T-shaped guide rod 205. When the upward movement is too high, personnel temporarily stop. The process begins with sewage discharge. Then, manual valve 203 is opened, and the multi-stage electric telescopic rod 206 is activated in the forward direction. This drives piston plate 204 downwards, compressing the gas in the gas storage tank 2. Under this pressure, natural gas is sequentially discharged through L-shaped pipe 202, manual valve 203, external threaded pipe head, and the explosion-proof hose 100 above to the CNG pipeline truck inlet or an external natural gas storage tank for reuse. After discharge, personnel close manual valve 203, allowing the sewage discharge process to resume and the multi-stage electric telescopic rod 206 to be activated in the reverse direction for natural gas extraction and collection. This process is repeated to extract and collect natural gas from oil spills during sewage discharge. After collection, the natural gas is returned to the pipeline truck or supplied to an external natural gas storage tank for reuse via compression, reducing the waste of natural gas from direct emissions into the air and improving environmental and usage efficiency.

[0037] It should be noted that the preferred lithium battery is the Lunqu Technology P760S model lithium battery with integrated charge and discharge protection function. This model of lithium battery can provide safe power supply for the multi-stage electric telescopic pole 206. The right side of the multi-stage electric telescopic pole 206 is fixedly equipped with a control switch connected by a flexible wire. This method of establishing a power supply, control and electrical connection controlled by the switch through direct wire connection is a mature and well-known technology of conventional wire control of switch components, and will not be described in detail here.

[0038] The usage method of this embodiment is as follows: When using the safe and environmentally friendly tube bundle vehicle sewage discharge device, the explosion-proof hose 100 below is connected to the CNG tube bundle vehicle sewage discharge interface. When the personnel open the valve on the CNG tube bundle vehicle sewage discharge interface, the oil sludge is allowed to flow into the sewage collection tank 1 through the explosion-proof hose 100 below. After the oil sludge is discharged into the sewage collection tank 1, it contains a large amount of natural gas. The stainless steel filter screen 401 is used to block the upward splashing of the entering oil sludge. The gas rises and passes through the filter holes of the stainless steel filter screen 401 itself, achieving the effect of blocking the oil sludge and filtering out the rising natural gas. The L-shaped vent pipe 102 is used to connect to the external vent pipe to assist personnel in venting to a safe space more than three meters away from the ground when it is necessary to vent to the air.

[0039] When natural gas needs to be recovered and collected instead of directly released, during the sewage discharge process, personnel reverse-start the multi-stage electric telescopic rod 206 to drive the piston plate 204 to slide upwards within the gas storage tank 2. The piston plate 204 draws the natural gas floating in the collection tank 1 into the gas storage tank 2 through the one-way valve 201. As the piston plate 204 moves upwards, it also drives the two T-shaped guide rods 205 to move upwards. After connecting the explosion-proof hose 100 above to the CNG pipeline vehicle inlet or external natural gas storage tank, personnel judge the degree of upward movement of the piston plate 204 by the scale line on the left T-shaped guide rod 205. When the upward movement is too high, personnel temporarily stop the sewage discharge work, then open the manual valve 203 and forward-start the multi-stage electric telescopic rod 206 to drive the piston plate 204 downwards to compress the gas in the gas storage tank 2. Under pressure, natural gas is sequentially discharged through L-shaped pipe 202, manual valve 203, external threaded pipe head, and explosion-proof hose 100 to the CNG tube bundle vehicle inlet or external natural gas storage tank for reuse. After discharge, personnel close manual valve 203, which allows the sewage discharge work to be restarted and the multi-stage electric telescopic rod 206 to be activated in reverse for natural gas extraction and collection. This process is repeated to achieve the effect of extracting and collecting natural gas from oil spills during sewage discharge, and then returning the natural gas to the tube bundle vehicle or supplying it to the external natural gas storage tank for reuse through pressure discharge. This reduces the waste of natural gas by direct emission into the air, improves environmental protection and usage efficiency, and reduces the safety hazards caused by excessive single-time emissions of natural gas into the atmosphere, thus improving usage safety.

[0040] The pressure gauge 3 is used to detect and display the pressure inside the sludge collection box 1, so that personnel can judge the natural gas extraction status by judging its internal pressure. Afterwards, personnel can transfer this device to an external hazardous waste disposal site and open the drain valve 101 to discharge the collected oil sludge for hazardous waste disposal. The temporary collection of sludge in the sludge collection box 1 avoids the phenomenon of direct and random on-site discharge that pollutes the environment.

[0041] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
