Problems solved by technology

[0002] Volatile oils such as benzene, alcohol, washing oil, etc. have strong volatility, and the internal pressure increases due to the volatility during storage, which requires higher pressure-bearing performance of the storage equipment, which greatly increases the storage cost. At the same time, the high internal pressure causes the storage equipment to be easily broken, which has a strong safety hazard, and the volatile oil gas is flammable and highly toxic. Once leaked, it will easily cause environmental pollution and explosive safety accidents

Embodiment 1

[0032] A VOCs zero-emission storage system for organic material storage tanks, comprising N storage tanks 1, a dry gas cabinet 2, a pressure balance main pipe 3, N pressure balance branch pipes 4, and a purification recovery device. The dry gas cabinet 2 has a high position limiting device and a pressure safety valve. The storage tank 1 is provided with a liquid level gauge for displaying its liquid level. The storage tank 1 has a feed port, a discharge port and an exhaust port. N storage tanks 1 pass through the pressure balance branch pipe 4 and the pressure balance main pipe 3. One end is connected, and the other end of the pressure balance main pipe 3 is connected with the dry gas cabinet 2. The dry gas cabinet 2 has a pressure balance pipe interface, a recycle gas inlet and a recovery gas outlet. A nitrogen replenishment pipe can also be externally connected to the connecting pipe of the circulating gas inlet.

[0033] The purification recovery device includes an adsorp...

Embodiment 2

[0039] A zero-emission storage method for VOCs in an organic material storage tank:

[0040] S1. Sealed connection: connect the storage tank to the pressure balance main pipe through the pressure balance branch pipe, and then connect the pressure balance main pipe to the dry gas cabinet;

[0041] S2. Initial phase setting: Set the constant pressure value of the dry-type gas holder according to the storage capacity of the storage tank. When the storage tank is completely empty, the internal pressure connected between the storage tank and the dry-type gas holder is at the lowest position, which is the initial position , the gauge pressure inside the dry-type gas holder is zero at this time;

[0042] S3. Gas protection: before the storage tank enters the material, the internal air is replaced by a circulating gas discharge system, so that the inner cavity of the storage tank is completely filled with circulating gas, and the inner cavity of the tank forms an oxygen-free environme...

Abstract

The invention discloses an organic material storage tank VOCs zero emission storage system which comprise N storage tanks, a dry gas cabinet, a pressure balance main pipe, N pressure balance branch pipes and a purifying recycling device. Each storage tank is provided with a feeding port, a discharging port and an exhaust port. The N storage tanks are connected with one end of the pressure balancemain pipe through the pressure balance branch pipes, and the other end of the pressure balance main pipe is connected with the dry gas cabinet. The dry gas cabinet is provided with a pressure balancepipe connector, a circulation gas inlet and a recycled gas outlet. The purifying recycling device comprises an adsorption device and a condensation heat exchanger. By means of the organic material storage tank VOCs zero emission storage system, due to the fact that the dry gas cabinet is connected with the storage tank, volatile gas of easily-volatile oils is buffered through the dry gas cabinet,the pressure intensity is increased, the storage danger is greatly lowered, the storage cost is low, maintenance is easy and convenient, and running is safe, reliable and durable.

Description

technical field [0001] The invention relates to the technical field of organic material storage equipment, in particular to a VOCs zero-emission storage system and method for an organic material storage tank. Background technique [0002] Volatile oils such as benzene, alcohol, washing oil, etc. have strong volatility, and the internal pressure increases due to the volatility during storage, which requires higher pressure-bearing performance of the storage equipment, which greatly increases the storage cost. At the same time, the high internal pressure causes the storage equipment to be easily broken, which has a strong safety hazard, and the volatile oil gas is flammable and highly toxic. Once leaked, it will easily cause environmental pollution and explosive safety accidents. Contents of the invention [0003] The object of the present invention is to provide a VOCs zero-emission storage system and method in an organic material storage tank to solve the above-mentioned t...
