Embodiment Construction

[0017] Attached below figure 1 The method for using the VOCs zero-emission device of the oil storage tank breathing valve of the present invention will be described in detail below.

[0018] Invented oil storage tank breathing valve VOCs zero emission device, including: oil storage tank 1, breathing valve 2, breathing valve cover 3 barrels, soft bag 4, compressor 5, condenser 6, chiller 7, storage tank 8, oil pump 9 , Shut-off valve 10.

[0019] The exhalation port of the breathing valve 2 is opened, and the exhaled VOCs organic waste gas enters the soft bag 4 through the breathing valve cover tube 3, and the gas pressure in the soft bag 4 increases. When the pressure is greater than the set value of the soft bag 4, the compressor 5 is turned on, VOCs organic waste gas enters the compressor 5 to be compressed, and the compressed VOCs waste gas enters the condenser 6 to condense, and the condensed VOCs gas-liquid mixture enters the storage tank 8 for storage. In the storage ta...

Abstract

The invention discloses an oil storage tank breather valve VOCs zero-emission device. The device comprises an oil storage tank, a breather valve, a breather valve cover cylinder, a soft bag, a compressor, a condenser, a water cooling machine, a storage tank, an oil pump and a stop valve, wherein the breather valve cover cylinder is arranged outside the breather valve and connected with the soft bag, the soft bag is connected with the compressor, the compressor is connected with the condenser, the condenser is connected with the storage tank, and the storage tank is connected with the soft bagand the oil storage tank separately. When pressure of the storage tank rises, the breather valve is opened, VOCs enter the soft bag, when pressure of the soft bag is larger than a set value, the compressor is started, and the VOCs enter the condenser to be condensed into liquid to enter the storage tank to be stored; and when pressure of the oil storage tank is low, the VOCs in the soft bag are sucked back into the oil storage tank through the cover cylinder and the breather valve, meanwhile, the stop valve is opened, the VOCs in the storage tank are supplemented into the soft bag, the pressure of the soft bag is increased to a set value, and the valve is closed. The device realizes zero emission of VOCs of the breather valve of the oil storage tank, and is an energy-saving and environment-friendly VOCs treatment technology.

Description

technical field [0001] The invention relates to the field of VOCs emission control of oil storage tanks, in particular to a VOCs zero emission device for a breather valve of an oil storage tank. Background technique [0002] As one of the most basic auxiliary production facility units in industrial production, oil storage tanks will generate a large amount of VOCs emissions during operation. Improper disposal will cause a series of problems such as waste of resources, environmental pollution, and health damage. In addition, the VOCs produced by the emission are mixed with air, which is easy to form an explosive mixture, and is prone to explosion accidents. [0003] The storage discharge of the oil storage tank is divided into static discharge (small breath) and working discharge (big breath). The breathing valve in the oil storage tank relies on the weight of the valve disc itself, and controls the valve to take off according to the pressure in the tank. It is the main VOCs...
