Description

Technical Field

[0001] The utility model relates to the technical field of oil and gas monitoring, in particular to an oil and gas recovery detector. Background Art

[0002] Oil and gas recovery refers to the process of refueling at a gas station, in which the oil and gas volatilized from the gasoline transported from the tanker or oil storage tank to the refueling gun is recovered back to the tanker or oil storage tank to reduce the emission of air pollutants. The oil and gas recovery detector is used for gasoline oil and gas emission management at existing gas stations, as well as environmental impact assessment, design and post-construction oil and gas emission management of new, modified and expanded gas station projects.

[0003] The existing oil and gas recovery detector mainly includes an oil gun holder, a detection instrument and a tank body for storing gasoline. However, the tank body and the detection instrument are separate. When in use, the oil gun holder needs to be fixed at the oil inlet of the tank body, and then the oil gun is inserted into the oil gun holder. Since the oil gun holder cannot stably fix the oil gun, the inspector needs to hold the oil gun all the time when starting the inspection until the inspection is completed, which makes the inspection process more laborious; secondly, since the existing tank body generally has an oil drain hose installed at the bottom, when the inspection is completed, the tank body needs to be lifted to discharge the gasoline along the bottom hose, so it is easy to have incomplete oil drainage. Therefore, the utility model proposes an oil and gas recovery detector. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes an oil and gas recovery detector.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an oil and gas recovery detector, including a base plate, an oil storage tank is fixedly installed on the upper surface of the base plate, an oil inlet pipe is fixed on the top of the oil storage tank, an oil gun seat is fixedly connected to the top of the oil inlet pipe, an oil and gas detector is installed on the oil gun seat, a clamping assembly for fixing the oil gun is installed on the top of the oil gun seat, an oil drain pipe is fixedly connected to the bottom of the oil storage tank, and the outlet of the oil drain pipe extends upward, an exhaust pipe is fixedly connected to the top wall of the oil storage tank, an air pump is fixed to the upper surface of the base plate, and the air pump outlet is fixedly connected to the air inlet pipe, and the other end of the air inlet pipe is fixedly connected to the top of the oil storage tank.
