Embodiment 1

[0036] Such as Figure 1-2 As shown, the present invention provides a comprehensive treatment system for storage tank VOCs, including: a tank body 100 and a floating roof 200; the floating roof 200 is slidably arranged in the tank body 100, and A manhole well 001, a vent valve 002 and a sampling tube 003 are provided, and the outer wall of the sampling tube 003 is covered with a telescopic bag cover 004, and the telescopic bag cover 004 is wrapped on the side wall of the sampling tube 003, and the telescopic bag One end of the cover 004 is fixed on the floating top cover 200, the other end of the telescoping bag cover 004 is fixed on the top of the sampling tube 003, the top of the tank body 100 is fixed with a first diaphragm 400, the first The diaphragm 400 is clamped by two clampable ring-shaped members, and the clampable ring-shaped member is fixed on the top of the inner wall of the tank body 100, and the other end of the first diaphragm 400 is connected to the outer surf...

Embodiment 2

[0044] Such as Figure 3-5 As shown, the lower waist of the first diaphragm 400 is fixedly connected to the upper end of the oil scraper 300, and the first diaphragm 400 located between the oil scraper 300 and the outer ring of the floating roof 200 is tightened; A safety hole 320 is provided on the oil scraper 300; and the safety hole 320 is connected to the annular chamber 410 formed by the first diaphragm 400 and the upper compression plate 210; in short, the safety hole 320 is provided on the oil scraper 300, and The position of the safety hole 320 is higher than that of the sawtooth 310, and the annular chamber 410 only has the safety hole 320 to communicate with the outside world. , the blocking effect of VOCs is reduced, VOCs can pass into the annular chamber 410 through the safety hole 320, the part of the first diaphragm 400 covering the annular chamber 410 can be lifted, can be identified visually, and can detect sealing problems in time.

Abstract

The invention provides a storage tank VOCs comprehensive treatment system. The storage tank VOCs comprehensive treatment system comprises a tank body and a floating roof cover; the floating top cover is arranged in the tank body in a sliding mode, a manhole well, a vent valve and a sampling pipe are arranged on the floating top cover, the outer wall of the sampling pipe is sleeved with a telescopic bag sleeve, the telescopic bag sleeve wraps the side wall of the sampling pipe, one end of the telescopic bag sleeve is fixed to the floating top cover, the other end of the telescopic bag sleeve is fixed to the top of the sampling pipe, and a first diaphragm is fixed to the top of the tank body. The other end of the first diaphragm is fixedly connected with the outer ring of the floating roof cover; an upper compression plate is arranged on the circumferential side wall of the floating roof cover in a surrounding mode, and the outer ring of the upper compression plate is attached to the inner wall of the tank body. The storage tank VOCs comprehensive treatment system further comprises an oil scraping plate, sawteeth with tooth tips facing the bottom of the tank body are arranged on the outer ring of the oil scraping plate, the oil scraping plate is fixed to the upper end of the upper compression plate, the sawteeth are attached to the tank body, and a sensor for measuring the concentration of VOCs is arranged inside or outside the first diaphragm. The floating roof cover and the tank body can be sealed through the upper compression plate and the first diaphragm.

Description

technical field [0001] The invention relates to the field of storage tanks, in particular to a storage tank VOCs comprehensive treatment system. Background technique [0002] Storage tanks are generally used to cooperate with the floating roof to realize the storage of the medium. During the gradual decrease or increase of the medium, the floating roof will always stick to the upper surface of the medium and as the medium descends or rises, it will rise and fall as a whole. In the process of descending, a good sealing effect in the circumferential direction of the floating roof becomes particularly important. In the prior art, an annular seal is generally used to achieve circumferential sealing. [0003] However, this type of sealing cannot deal with the residues on the inner wall of the storage tank, resulting in the overflow of VOCs gas. Therefore, it is necessary to provide a comprehensive VOCs treatment system for storage tanks that can effectively isolate the medium and...
