AI Technical Summary
Existing vapor recovery systems for gasoline vapors are complex, expensive, and fail to effectively prevent inhalation of vapors during refueling, necessitating a more cost-effective and efficient solution.
A device using a directed airflow from an uncontaminated source to displace gasoline vapors from the refueling area, comprising an external air intake, air ducts, fans, and a control system to manage airflow, activated by a sensor during refueling.
Effectively reduces gasoline vapors in the breathing zone by displacing them away from the refueling area, ensuring no direct contact and minimal maintenance.
Abstract
Description
1. Title of the invention:
[0001] "Device for displacing gasoline vapors during refueling of a vehicle by means of an external directed air supply and thus a change in the airflow" 2. Technical field:
[0002] The invention relates to a device for reducing the inhalation of harmful gasoline vapors during refueling. It uses an airflow supplied from a remote, uncontaminated source to displace the vapors from the breathing zone of the person refueling. 3. State of the art:
[0003] Known solutions are primarily based on vapor recovery systems that extract gasoline vapors and return them to the gas station's storage tank. These systems are technically complex and expensive. Nevertheless, gasoline vapors still occur in the breathing zone of the person refueling. This invention can be used to significantly reduce the amount of gasoline vapors in the breathing zone. No devices are currently known that utilize a targeted supply of air from a remote, uncontaminated environment to effectively displace the gasoline vapors. 4. Object of the invention:
[0004] The invention is intended to provide a cost-effective, energy-efficient and low-maintenance way to displace gasoline vapors from the breathing zone of the person refueling by: - Fresh air is supplied from an unpolluted environment, - the solution can be retrofitted to existing gas stations, - the device works automatically and - no direct contact of the airflow with the gasoline vapors is required. 5. Solution to the task:
[0005] The invention comprises a device (hair dryer system) that generates a directed flow of fresh air to displace gasoline vapors from the person's breathing area when refueling vehicles, The device consists of: - At least one external air intake opening located away from the fuel pump in an uncontaminated environment, - Air ducts that direct uncontaminated fresh air to the gas station, - One or more fans that generate the airflow and direct it specifically into the area around the vehicle and the person refueling, - A sensor that detects the refueling process and activates the device, - A control unit that regulates the direction and intensity of airflow.
[0006] The fresh air displaces the gasoline vapors in a direction where they can dissipate freely or be vented through existing exhaust systems.
Claims
[1] Device for displacing petrol vapors during refueling of a vehicle comprising: a) at least one air inlet opening located in an uncontaminated environment, b) a duct system that directs the supplied fresh air from the air inlet opening to the tank area, c) at least one fan that directs fresh air towards the tank area, d) a control unit that regulates the airflow depending on a refueling process, e) a sensor that detects the start of a refueling process and activates the device. [2] Device according to claim 1, wherein the air inlet opening is mounted higher to ensure better air quality. [3] Device according to claim 1 or 2, wherein the piping system consists of flexible or rigid pipes. [4] Device according to one of the preceding claims, wherein the control unit adjusts the airflow intensity depending on the outside temperature and wind direction. [5] Device according to one of the preceding claims, wherein the airflow is directed such that it displaces the gasoline vapors laterally or downwards from the breathing area of the person refueling.
