Description

Technical Field

[0001] This utility model relates to the field of alkane recovery technology, specifically to a highly safe alkane recovery device. Background Technology

[0002] Alkane recovery equipment is an environmentally friendly device for treating alkane waste gas. It extracts alkane substances or gases from waste gas through various processes such as adsorption and condensation for recycling and reuse. This can effectively reduce the emission of volatile organic compounds and industrial pollution. At the same time, alkane materials can be recycled and reused, thereby reducing raw material consumption. It is widely used in chemical, new energy and other industries.

[0003] For example, the insoluble alkane volatile waste gas condensation and recovery device disclosed in announcement number CN213286239U includes a condensation absorption tower, an oil-water separator, an organic solvent storage tank, a circulating water pump, a heat exchanger, and a liquid flow meter. This utility model uses low-temperature water to condense and recover insoluble alkane volatile waste gas. The water in this device can be recycled after being cooled by heat exchanger, saving water resources and avoiding the problem of a large amount of solid waste generated by the activated carbon adsorption method.

[0004] Most of the aforementioned existing technologies improve the overall structure. However, in the operation of existing alkane recovery equipment, the inside of the recovery device is mostly filled with natural air. When oxygen in the air comes into contact with some alkane gases, it can easily form an explosive mixture, thereby increasing the risk factor and reducing the safety of the device during use. Utility Model Content

[0005] The purpose of this invention is to provide a highly safe alkane recovery device to solve the problem mentioned in the background art that most existing alkane recovery devices are filled with air.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a highly safe alkane recovery device, comprising a protective component and two adsorption components installed inside the protective component. Each adsorption component has an exhaust pipe fitted at its upper end. A guide pipe is installed inside the protective component, and a storage component is provided at the rear end of the protective component. A gas pre-filling component is provided below each adsorption component, enabling the conversion of the gas inside each adsorption component into an inert gas before use. Each exhaust pipe has a gas guiding component inside, enabling the guidance of different gases to different pipes when different gases are released onto the adsorption components.

[0007] Furthermore, the protective assembly includes a protective housing inside, a top cover is slidably installed on the top of the protective housing, and a front baffle is slidably installed on the front end of the protective housing.

[0008] Furthermore, an inspection door is rotatably installed inside the front baffle, and an operation panel is fixedly installed inside the front baffle.

[0009] Furthermore, each of the adsorption components includes an adsorption tower inside, and three support legs are fixedly installed at the lower end of each adsorption tower, while a first connecting pipe is fixedly installed at the side end of each adsorption tower.

[0010] Furthermore, each of the gas prefilling components includes a one-way valve, a second connecting pipe is fixedly installed on the side end of each one-way valve, an air pump is installed at the lower end of each one-way valve, the upper part of each one-way valve is connected to the opening at the bottom of the adsorption tower, and the lower part of each one-way valve is connected to the upper output shaft of the air pump.

[0011] Furthermore, each of the second connecting pipes is equipped with the same third connecting pipe at its side end. The outer surface of the third connecting pipe is fitted with a second guide valve, and a heater is fixedly installed at the side end of the second guide valve.

[0012] Furthermore, the storage assembly includes an air storage tank, the side end of which is connected to a heater, and the interior of which is connected to the interior of a third connecting pipe.

[0013] Furthermore, a drying filter tube is fitted onto the outer surface of the guide tube, and a first guide valve is fitted onto the side end of the guide tube. The output ports on both sides of the first guide valve are connected to the first connecting tube.

[0014] Furthermore, each of the gas guiding components includes an exhaust pipe, a collection pipe is fixedly sleeved on the outer surface of each exhaust pipe, a blocking plate is rotatably installed inside each collection pipe, a servo motor is fixedly installed on the outer surface of each collection pipe, and the side end of each blocking plate is connected to the output shaft of the servo motor via a spline.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This highly safe alkane recovery equipment uses a gas pump and a one-way valve to extract inert gas from the storage tank and introduce it into the adsorption tower for storage. Then, the gas is discharged through a guide pipe to facilitate adsorption operations inside the adsorption tower. This allows the air inside the device to be replaced with inert gas during use, thereby preventing the formation of an explosive mixture between alkane and air and maintaining the safety of the device.

[0017] Furthermore, by opening or closing the servo motor to adjust the angle of the baffle plate inside the exhaust pipe, the direction of gas flow inside the device can be adjusted. This allows for convenient adjustment of the gas flow direction during use, facilitating the extraction of different gases and improving the efficiency of the device. Attached Figure Description

[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] Example 1: Please refer to Figures 1-6A highly safe alkane recovery device is disclosed to address the safety hazard caused by internal gases easily inducing alkane reactions during operation in existing alkane recovery devices. The device comprises a protective component 1 and two adsorption components 2 installed inside the protective component 1. Each adsorption component 2 has an exhaust pipe 35 fitted at its upper end. A guide pipe 27 is installed inside the protective component 1, and a storage component 3 is located at the rear end of the protective component 1. A gas pre-filling component is located below each adsorption component 2, which converts the internal gas of each adsorption component 2 into an inert gas before use. Each exhaust pipe 35 has a gas guiding component inside, which guides different gases released onto the adsorption component 2. For operations inside different pipelines, each gas pre-filling assembly includes a one-way valve 24. A second connecting pipe 25 is fixedly installed on the side end of each one-way valve 24. An air pump 26 is installed at the lower end of each one-way valve 24. The upper part of each one-way valve 24 is connected to the bottom opening of the adsorption tower 21. The lower part of each one-way valve 24 is connected to the upper output shaft of the air pump 26. The side end of each second connecting pipe 25 is equipped with the same third connecting pipe 34. A second guide valve 33 is sleeved on the outer surface of the third connecting pipe 34. A heater 32 is fixedly installed on the side end of the second guide valve 33. The interior of the storage assembly 3 includes a gas storage tank 31. The side end of the gas storage tank 31 is connected to the heater 32. The interior of the gas storage tank 31 is connected to the interior of the third connecting pipe 34.

[0027] Before using the device, the user first operates the control panel 15 to start the air pump 26, and simultaneously adjusts the second guide valve 33 so that it connects only to the second connecting pipe 25 on one side inside the protective housing 11. When the air pump 26 starts, in conjunction with the internal structure of the one-way valve 24, it can draw inert gas stored in the gas storage tank 31 through the second connecting pipe 25 and the one-way valve 24, and introduce it into the adsorption tower 21 to replace the air in the adsorption tower 21. Then, the user connects the delivery pipe to the guide pipe 27 to deliver the gas to be treated. The gas is introduced into the guide tube 27 and passes through the drying filter tube 28 as it moves within the guide tube 27. The desiccant in the drying filter tube 28 dries the gas and removes the moisture contained in the gas. Then, the first guide valve 29 is operated to guide the material gas in the guide tube 27 into the adsorption tower 21 containing inert gas. Adsorption and separation operations are carried out in the adsorption tower 21 to recover alkanes. The gas with the alkanes removed is continuously pushed by the bottom gas pump 26 and enters the exhaust pipe 35.

[0028] Example 2: Figures 1-6The technical solution shown, based on Embodiment 1, further discloses the following to address the problem that existing alkane recovery equipment is inconvenient for recovering alkane gas filtered from the device: Each adsorption component 2 includes an adsorption tower 21, with three support legs 22 fixedly installed at the lower end of each adsorption tower 21, and a first connecting pipe 23 fixedly installed at the side end of each adsorption tower 21. The protective component 1 includes a protective housing 11, with a top cover 12 slidably installed on the top of the protective housing 11, and a front baffle 13 slidably installed on the front end of the protective housing 11. A maintenance access panel is rotatably installed inside the front baffle 13. The door 14 and the front baffle 13 are fixedly installed with an operation panel 15. The outer surface of the guide tube 27 is fitted with a drying filter tube 28. The side end of the guide tube 27 is fitted with a first guide valve 29. The output ports on both sides of the first guide valve 29 are connected to the first connecting pipe 23. Each gas guide assembly includes an exhaust pipe 35. The outer surface of each exhaust pipe 35 is fixedly fitted with a collection pipe 36. The inside of each collection pipe 36 is rotatably installed with a blocking plate 37. The outer surface of each collection pipe 36 is fixedly installed with a servo motor 38. The side end of each blocking plate 37 is connected to the output shaft of the side end of the servo motor 38 through a spline.

[0029] When the gas to be discharged enters the exhaust pipe 35, the servo motor 38 is not started. The blocking plate 37 will be perpendicular to the inner wall of the collecting pipe 36, thereby blocking the side opening. Then the gas continues to move upward to the discharge device. When the adsorption tower 21 is saturated, the user first adjusts the second guide valve 33 to introduce the inert gas into another adsorption tower 21 in the same way. Then, the user adjusts the first guide valve 29 to change the material gas delivery direction and introduce the material gas into another adsorption tower 21 to continue the reaction. Then the user starts the heater 32 to... The third connecting pipe 34 is heated, causing the gas temperature inside the third connecting pipe 34 to rise. After reaching the preset temperature, the second guide valve 33 changes again, introducing the heated inert gas into the previously saturated adsorption tower 21. The heated temperature desorbs the gas inside the adsorption tower 21. At this time, the servo motor 38 is started, and the servo motor 38 drives the blocking plate 37 to rotate and cooperate with the upper blocking of the exhaust pipe 35 to block the upper opening of the exhaust pipe 35, so that the gas can be discharged from the internal opening of the collection pipe 36, thereby facilitating the recovery of alkane gas in the material.
