Description

Novel connect liquid stand to pass through entirely device

Technical Field

The utility model relates to an interior floating roof storage tank floating plate sealing field, in particular to novel connect liquid stand entirely to pass through device.

Background

In the process of oil product storage and turnover, high-concentration oil gas can be formed in a storage tank by medium evaporation, so that explosion accidents, environmental pollution, energy loss and other hazards are caused. In recent years, the problem of oil volatilization is solved by adopting a full liquid-receiving floating disc, the total loss of a floating roof tank is indicated to comprise peripheral loss, wall-hanging loss, accessory loss and disc seam loss according to the 'inspection working guide for VOCs pollution sources in petrochemical industry' 2015-104, the accessories such as a negative pressure eliminating device, a manhole device and a sampling device are all sealed in an immersion liquid manner to reduce the loss of VOCs, the opening condition of the side wall of a storage tank stand column is generally sealed by a wrapping type telescopic bag sleeve, oil gas emitted from the opening position of the stand column is always wrapped in the telescopic bag sleeve and cannot be discharged into the outside air to cause harm, but the problem of how to solve the dynamic sealing between the stand column and the floating disc becomes the primary problem in the case of no opening of the side wall of the stand column.

The traditional upright post passes through the device and only uses fluororubber or nitrile rubber sealing tape to carry out surface sealing at the upper end of the Harvard port, and the full liquid-receiving design is not reached (as shown in figure 1), so that an oil-gas space of about 241.25mm exists between the top of the Harvard port and the liquid level. A large amount of oil gas is volatilized in the operation process of the storage tank, so that the treatment effect of the VOCs is poor, and safety accidents such as fire disasters and explosions can be caused if the VOCs are badly led out in case of static electricity or in case of thunderstorm weather.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a novel connect liquid stand entirely and pass through the device, reach the source and administer the VOCs theory, when restraining that oil gas is volatile, increased the security of storage tank.

The novel full-liquid-receiving upright post passing device comprises a half port module, a sealing system and an upright post, wherein the sealing system comprises a sealing bag and an anti-turnover hook;

a flange ring is arranged at the upper end of the half port module, one end of the sealed bag is fixed to the flange ring through a fastening bolt, the other end of the sealed bag is vertically downward, an anti-turnover hook used for fixing the sealing system is installed inside the sealed bag, the other end of the sealed bag is arranged in a U shape around the stand column and is fixed to the flange ring at the upper end of the half port module to form a closed loop; and irregular sealing sponge is filled in the sealing bag.

Preferably, each half die block is provided with two anti-turnover hooks.

Preferably, the sealed bag and the haven module are fastened through a sealed pressing plate, so that a closed circular ring is formed by a sealing effect.

Preferably, the sealing system is tightly attached to the haversian module and the upright column, so that the floating disc is always immersed below the liquid level of the liquid storage when ascending or descending.

Preferably, the sealing bag is made of fluororubber, nitrile rubber, ethylene propylene diene monomer rubber or other materials suitable for storing liquid.

Preferably, the sealing sponge is polyurethane sponge or other materials capable of meeting the sealing requirement.

Preferably, the anti-turnover hook, the fastening bolt and the sealing pressure plate are all made of S30408 stainless steel.

The beneficial effects of the utility model are that:

the utility model is applied between the storage tank upright post and the floating disc dynamic seal, the sealing system is directly contacted with the liquid storage, thereby ensuring no oil gas space in the sealing area, reducing the volatilization of VOCs and simultaneously improving the operation safety of the storage tank; the sealing material has no corrosion to the product, no reaction and no pollution to the stored liquid; the service life is as long as 10 years, and the practicability and the economy are improved; the reliability of the sealing device is ensured by the irregular sealing sponge in the sealing bag.
