INSTALLATION vapor recovery from the tank OIL TANKS AND MACHINES FOR REFUELING

摘要

The invention relates to a device for collecting oil vapor and can be used in the petrochemical and other petroleum products industries. The solution of this object is achieved in that the breathing valves of tanks at filling stations are equipped with system of pipelines connected to the main steam pipe connected to the underground tanks with low octane component, which is equipped with a receiver and a shaft for rotation of the centrifugal wheel, wherein the main steam line passes cooling system comprising a heat exchanger , pump and a container with a cooling mixture. And also the fact that the pair of tanks machine unit through a dual distributing sleeve and a portion of steam pipe is pumped into a separate tank equipped with check valves with different pressures the opening, wherein the pressurized working oil vapors unit accumulate in the tank and periodically via a check valve the pressure-fed into the main steam line with the cooling system, and then to the reservoir for further absorption. The utility model is as follows. After draining device oil is supplied into the tank. With increasing pressure rises vent valve plate and a pair of open piping system, the check valve to enter the main pipeline connected with an additional tank equipped with a receiving device. Vapors pass heat exchanger with the pumped fluid that is supplied from the vessel via conduit a cooling system with a pump. The main part of the gaseous hydrocarbons as a result of cooling in the heat exchanger passes into the liquid state, and the pairs are not passed into the liquid, stratified two partitions with holes of different diameters and absorbed nizkooktanovoj component. Undissolved portion of gaseous hydrocarbons at the outlet from the reservoir is collected filter-absorber. Ingress of vapor in the tank prevents the check valve. Vapors from the vehicle tank during refueling petroleum product being replaced. By using bi-arm unit through the low pressure steam line portion and a non-return valve pairs fall into the tank for collecting vapors. In this tank to accumulate pairs reverse pressure-valve opening pressure. When reaching the opening pressure of the check valve gauge through a communication line and the relay includes an electric motor, which starts to rotate the shaft with centrifugal wheels for spraying low octane components throughout the tank volume. Also through the communication line relay includes a pump for supplying coolant mixture through the heat exchanger. After opening the pairs of the pressurized oil return valve fed by the steam line to the heat exchanger with the fluid cooling mixture. Then, the vapor mixture with the liquid petroleum product is supplied to the receiving device and into the tank to a rotational shaft of the centrifugal wheel. The tank is absorbed oil vapor is sprayed over the entire volume of low octane component. After closing the pressure-check valve operator opens the valve, and a pair of oil pressure due to the increased similarly fed into the reservoir and absorbed by the low-octane component.
