Description

Technical Field

[0001] This utility model relates to the field of gas odorization technology, and in particular to a gas odorization device. Background Technology

[0002] As a widely used clean energy source, natural gas is colorless and odorless, making leaks difficult to detect and easily leading to serious safety accidents such as explosions and poisoning. To solve this problem, odorants with strong odors are usually injected into the natural gas so that leaks can be identified by personnel in time. Traditional odorizing equipment mostly uses mechanical or pressure-driven methods to inject odorants.

[0003] Currently, although there are some odorization devices on the market, some devices have problems such as complex structure, inconvenient operation, and inaccurate control of odorization amount. Some devices are difficult to guarantee a stable quantitative output when extracting odorant, resulting in uneven odorization and affecting the effectiveness of gas leak detection. Therefore, it is necessary to install a gas odorization device. Utility Model Content

[0004] The purpose of this invention is to provide a gas odorization device to solve the problems existing in the prior art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A gas odorization device includes a support frame and further includes:

[0007] A liquid storage tank is fixedly installed on the top of a bracket. The liquid storage tank is used to store odorant, and a filling port is provided at the top of the liquid storage tank.

[0008] A pressure testing pipeline, one end of which is connected to the top of the inside of the liquid storage tank, and the other end of which is an odor inlet, which is connected to a first shut-off valve;

[0009] An odorizing pump unit is provided, which is located at the bottom of the pressure measuring pipe, and one end of the odorizing pump unit is connected to the pressure measuring pipe.

[0010] The liquid outlet pipe has one end connected to the bottom of the storage tank and the other end connected to the other end of the odor pump unit.

[0011] By adopting the above technical solution, the odorant in the storage tank flows out from the bottom of the storage tank, flows through the outlet pipe to the odor pump unit, and the odor pump unit is used to quantitatively extract the odorant in the storage tank, and then stably and reliably inject the odorant into the gas pipeline through the first shut-off valve, adding odorous gas to the gas, making it easier to identify the gas leak.

[0012] In a further embodiment, a first ball valve and a Y-type filter are spaced apart on the liquid outlet pipe. The first ball valve is located at the end of the liquid outlet pipe closer to the storage tank, and the Y-type filter is located at the end of the liquid outlet pipe farther from the storage tank. Both the first ball valve and the Y-type filter are connected to the liquid outlet pipe.

[0013] By adopting the above technical solution, the first ball valve is opened, and the odorizing pump unit draws odorant from the storage tank. The drawn odorant will pass through a Y-type filter before reaching the odorizing pump unit. Because there may be tiny impurities in the odorant, the Y-type filter is needed to filter out the tiny impurities to prevent them from entering the metering pump unit and causing wear or blockage, thus protecting the odorizing pump unit and the downstream valves.

[0014] In a further embodiment, a second shut-off valve, a needle valve, a pressure gauge, a straight-through level gauge, and a check valve are spaced apart on the pressure measuring pipe. The second shut-off valve, needle valve, straight-through level gauge, and check valve are sequentially connected to the storage pipe from the end of the pressure measuring pipe near the storage tank to the end of the pressure measuring pipe away from the storage tank. The pressure gauge is detachably installed on the top of the needle valve.

[0015] By adopting the above technical solution, the second shut-off valve is closed, isolating the pressure measuring pipeline into a first pipeline and a second pipeline. The first pipeline is at the top of the second ball valve, and the second pipeline is at the bottom of the needle valve. This allows the pressure gauge to monitor the pipeline pressure in the second pipeline after adjustment by the needle valve in real time. The needle valve is used to control the flow rate of the odorant in the second pipeline. By observing the pressure gauge reading, the operator can determine whether the odor pump unit is working properly. The operator can also fine-tune the opening of the needle valve to ensure that the odorant is injected into the gas pipeline within a suitable and stable pressure range. At the same time, when it is necessary to disassemble or replace the pressure gauge, the needle valve can be closed first, so that the operator can safely remove the pressure gauge without releasing system pressure or affecting system operation. The check valve can prevent high-pressure gas from flowing back into the odorizing device. The operator can observe the liquid flow through the straight-through level gauge to confirm whether the equipment is operating.

[0016] In a further embodiment, the odorizing pump unit is disposed between the needle valve and the straight-through level gauge. The odorizing pump unit includes a first pump assembly and a second pump assembly. The second pump assembly is spaced apart at the left end of the first pump assembly. The first pump assembly and the second pump assembly have the same structure. The first pump assembly includes a solenoid valve metering pump, a third shut-off valve, and a fourth shut-off valve. The inlet end of the third shut-off valve is connected to the end of the outlet pipe away from the storage tank. The outlet end of the third shut-off valve is connected to the inlet end of the solenoid valve metering pump. The outlet end of the solenoid valve metering pump is connected to the inlet end of the fourth shut-off valve. The outlet end of the fourth shut-off valve is connected to the middle section of the pressure measuring pipe.

[0017] By adopting the above technical solution, the solenoid valve metering pump quantitatively extracts the odorant. The third and fourth shut-off valves are used to isolate the solenoid valve metering pump from the liquid outlet pipeline and the pressure measuring pipeline. When maintenance, replacement of the solenoid valve metering pump or cleaning of the Y-type filter is required, the third and fourth shut-off valves are closed.

[0018] In a further embodiment, a drain pipe is provided at the bottom of the liquid storage tank, one end of which is connected to the interior of the liquid storage tank, and the other end of which is connected to a second ball valve.

[0019] By adopting the above technical solution, impurities or moisture that may accumulate at the bottom of the storage tank can be discharged through the sewage pipe and the first ball valve.

[0020] In a further embodiment, a magnetic level gauge is provided on one side of the storage tank.

[0021] In a further embodiment, the top of the storage tank is connected to one end of an adsorption pipe, the other end of the adsorption pipe is connected to one end of a flame arrester, and the other end of the flame arrester is connected to an activated carbon adsorption tank.

[0022] In a further embodiment, an explosion-proof box is also included, which is fixedly connected to the bracket.

[0023] In summary, this utility model has the following beneficial effects:

[0024] 1. The odorant in the storage tank flows out from the bottom of the storage tank and flows through the outlet pipe to the odor pump unit. The odor pump unit is used to quantitatively extract the odorant in the storage tank and then reliably and safely inject the odorant into the gas pipeline through the first shut-off valve, adding odorous gas to the gas and making it easier for personnel to identify when there is a gas leak.

[0033] A first ball valve 8 and a Y-type filter 9 are provided at intervals on the liquid outlet pipe 7. The first ball valve 8 is located at the end of the liquid outlet pipe 7 close to the liquid storage tank 2, and the Y-type filter 9 is located at the end of the liquid outlet pipe 7 away from the liquid storage tank 2. Both the first ball valve 8 and the Y-type filter 9 are connected to the liquid outlet pipe 7.

[0034] The pressure measuring pipe 3 is provided with a second shut-off valve 10, a needle valve 11, a pressure gauge 12, a straight-through level gauge 13 and a check valve 14 at intervals. The second shut-off valve 10, needle valve 11, straight-through level gauge 13 and check valve 14 are connected to the storage pipe in sequence from the end of the pressure measuring pipe 3 near the storage tank 2 to the end of the pressure measuring pipe 3 away from the storage tank 2. The pressure gauge 12 is detachably installed on the top of the needle valve 11.

[0035] Odor-adding pump unit 6 is located between needle valve 11 and straight-through level gauge 13. Odor-adding pump unit 6 includes a first pump assembly 61 and a second pump assembly 62. The second pump assembly 62 is spaced apart at the left end of the first pump assembly 61. The structures of the first pump assembly 61 and the second pump assembly 62 are identical. The first pump assembly 61 includes a solenoid valve metering pump 611, a third shut-off valve 612 and a fourth shut-off valve 613. The solenoid valve metering pump 611 is fixedly installed on the top of the support block. The inlet end of the third shut-off valve 612 is connected to the end of the outlet pipe 7 away from the storage tank 2. The outlet end of the third shut-off valve 612 is connected to the inlet end of the solenoid valve metering pump 611. The outlet end of the solenoid valve metering pump 611 is connected to the inlet end of the fourth shut-off valve 613. The outlet end of the fourth shut-off valve 613 is connected to the middle section of the pressure measuring pipe 3.

[0036] The bottom of the storage tank 2 is equipped with a drain pipe, one end of which is connected to the interior of the storage tank 2, and the other end of which is connected to a second ball valve 15; a magnetic float level gauge 16 is installed on one side of the storage tank 2; one end of the adsorption pipe 17 is connected to the top of the storage tank 2, and the other end of the adsorption pipe 17 is connected to one end of the flame arrester 18, and the other end of the flame arrester 18 is connected to the activated carbon adsorption tank 19, which is fixedly installed at the bottom of the vertical support; it also includes an explosion-proof box 20, which is fixedly connected to the top of the vertical support.

[0037] Specific implementation process: At the start of the odorization process, the first ball valve 8 on the outlet pipe 7 is opened, at which point the odorization pump unit 6 starts, drawing odorant from the bottom of the storage tank 2. The drawn odorant first passes through the Y-type filter 9, which effectively intercepts tiny impurities in the odorant, preventing them from entering the odorization pump unit 6 and causing wear or blockage, thus protecting the normal operation of the equipment. Subsequently, the odorant flows into the odorization pump unit 6, which includes a first pump assembly 61 and a second pump assembly 62. Taking the first pump assembly 61 as an example, the solenoid valve metering pump 611 quantitatively draws the odorant. During odorization, the odorant enters the solenoid valve metering valve through the third shut-off valve 612. Pump 611 then enters the pressure testing pipeline 3 through the fourth shut-off valve 613. On the pressure testing pipeline 3, the second shut-off valve 10 is closed to isolate the pressure testing pipeline 3 into two sections. The pressure gauge 12 can monitor the pipeline pressure after adjustment by the needle valve 11 in real time. The operator can judge whether the odorizing pump unit 6 is working properly by observing the reading of the pressure gauge 12, and fine-tune the opening of the needle valve 11 to ensure that the odorant is injected into the gas pipeline within a suitable and stable pressure range. At the same time, the check valve 14 can prevent high-pressure gas from flowing back into the odorizing device. Finally, the odorant is safely injected into the gas pipeline through the first shut-off valve 4 to complete the odorization, providing a reliable guarantee for gas leak detection.
