Abstract
Description
Technical Field
[0001] This utility model relates to the field of gas analysis technology in oil and gas exploration and development, specifically to a gas analyzer for oil and gas exploration and development. Background Technology
[0002] “In the process of oil and gas exploration and development, the composition analysis of oil and gas (including associated gases) is an important link to ensure production safety and environmental friendliness. As a key device for this analysis, the performance of the gas analyzer directly affects the reliability of the analysis results and the rationality of subsequent processing. Currently, most gas analyzers on the market process the analyzed gas by direct emission after completing the composition analysis of the mixed gas. However, oil and natural gas (including associated gases) often contain a variety of harmful / flammable and explosive components such as hydrogen sulfide, carbon monoxide, and methane. Direct emission of these harmful gases into the working environment will not only pollute the surrounding air and damage the ecological environment, but also seriously threaten the health of on-site workers and even cause safety accidents such as poisoning, posing a great challenge to the safety management of oil and natural gas exploration and development. In addition, although some gas analyzers attempt to treat exhaust gases in a simple way, they have obvious shortcomings in structural design: for example, the filter components used to filter harmful components are mostly fixed installations. When the filtration effect declines and needs to be replaced, the operation is cumbersome and time-consuming, affecting the continuous working efficiency of the equipment. At the same time, the lack of an effective gas collection and sealing structure makes it difficult to achieve centralized and safe transfer of treated gas, and there is still a risk of harmful gas leakage.

[0010] Preferably, the connecting pipe has a connecting plug with a valve and a corresponding one-way valve on the side near the negative pressure tank.
[0011] Compared with the prior art, the beneficial effects of this utility model are: By setting up a filter element composed of activated carbon filter cotton, harmful substances in the gas can be effectively adsorbed, significantly reducing the risk of harmful gases to the environment and personnel, and making the emitted gas safer and more environmentally friendly. The first and second slot plates are connected by an insertion mechanism. Combined with the threaded fixing method of the insertion rod and the sleeve, when the filter element needs to be replaced, simply remove the nut on the outer wall of the insertion rod and pull the second slot plate to the left to separate it from the first slot plate. The filter element can then be easily removed for replacement. The operation is simple and efficient, saving maintenance time. Equipped with a negative pressure tank made of high-strength pressure-resistant metal as a collection component, it can reliably collect filtered gas. The negative pressure tank is detachable and connected to the connecting pipe through a one-way valve. When separated, the one-way valve automatically seals to ensure that the gas does not leak during transportation, making it easy to transport it to a sparsely populated location for discharge and preventing harmful gases from accumulating in the work area. The first slot plate is made of wear-resistant and well-sealing engineering plastic. The second slot plate is adapted to the left slot size of the first slot plate. The positions of the insertion rod and the sleeve are corresponding, and the inner diameter of the sleeve is slightly larger than the diameter of the insertion rod, ensuring that the second slot plate can be accurately connected and fixed to the first slot plate. At the same time, the connection between the connecting pipe and the bottom end of the second slot plate is sealed with sealant to effectively prevent gas leakage and ensure the stability and reliability of the equipment in the gas analysis and processing process.

A first slot plate 2 is fixed on one side of the top of the gas analyzer 1. The gas analyzer 1 has a rectangular slot structure and is made of wear-resistant and well-sealed engineering plastic. A second slot plate 3 is inserted into the left side of the first slot plate 2. The size of the second slot plate 3 is adapted to the slot on the left side of the first slot plate 2. The interior is hollow and used to place a filter element 4. The interior of the second slot plate 3 is provided with a filter element 4 for filtering the gas. Insert rods 5 are fixed on both sides of the second slot plate 3. The insert rods 5 are symmetrically fixed on both sides of the second slot plate 3 and their positions correspond to the sleeves 6 on the first slot plate 2, ensuring that the second slot plate 3 can be accurately connected and fixed to the first slot plate 2. A sleeve 6 is fitted onto the outer wall of the insertion rod 5. The inner diameter of the sleeve 6 is slightly larger than the diameter of the insertion rod 5, allowing the insertion rod 5 to pass through smoothly. The outer wall of the sleeve 6 is connected to the side wall of the first slot plate 2. Sliding components are provided on both sides of the second slot plate 3. A connecting pipe 9 is fixed to the bottom end of the second slot plate 3. One end of the connecting pipe 9 is fixedly connected to the bottom end of the second slot plate 3, and the connection is sealed with sealant to prevent gas leakage. The other end is provided with a structure for connecting to the collection component, and is located near the negative... One side of the pressure tank 10 is machined with a valve and a corresponding one-way valve 11. The end of the connecting pipe 9 away from the second slot plate 3 is provided with a collection component for collecting the filtered gas. The outer wall of the insertion rod 5 is machined with threads. After the insertion rod 5 passes through the sleeve 6, it can be fixed by the nut to seal the first slot plate 2 and the second slot plate 3. The right side of the first slot plate 2 is connected to the gas outlet of the gas analyzer 1 through a hose. The filter element 4 is composed of activated carbon filter cotton and can filter the gas discharged from the gas analyzer 1.
[0016] The sliding assembly includes a slide rail 7, which is fixed to the top of the gas analyzer 1. A slider 8 is slidably connected inside the slide rail 7, and the inner side of the slider 8 is connected to the second slot plate 3. The collection assembly includes a negative pressure tank 10, which serves as a container for collecting filtered gas. It is made of high-strength pressure-resistant metal and has a sealing cap connected to one end via a thread for easy subsequent gas discharge.

A valve and a corresponding connecting plug for connecting the one-way valve 11 are machined on the side of the connecting pipe 9 near the negative pressure tank 10.
[0017] Working Principle: When a gas analyzer for oil and gas exploration and development is first used, gas enters the analyzer 1 through its inlet. The analyzer then analyzes the gas. The analyzed gas enters the sealed space formed by the first and second trough plates 2 and 3, connected by a hose to the exhaust port. After entering, the gas passes through an internal filter 4, which adsorbs harmful substances and reduces their concentration. The filtered gas then enters the negative pressure tank 10 through a connecting pipe 9. Once all the gas has entered the negative pressure tank 10, the user... Pull the negative pressure tank 10 to the right to separate it from the connecting pipe 9. When separated, the one-way valve will automatically seal. Then, the user can transport the negative pressure tank 10 to a sparsely populated location and open the sealing cover on the side wall of the negative pressure tank 10 to release the internal gas. After the harmful gas is adsorbed by the filter element 4, the released gas can effectively reduce the harm to the environment or personnel. When the filter element 4 needs to be replaced, the user can remove the nut on the outer wall of the plug rod 5 and then pull the second groove plate 3 to the left. When pulled, it will separate from the first groove plate 2. After separation, the user can take out the filter element 4 for replacement.
