Abstract
The utility model discloses a chlorine dioxide storage tank with an inner floating cover. A chlorine dioxide solution liquid inlet pipeline is arranged on the lower portion of a cylinder body, an anti-explosion cover plate, a pressure limiting hole and an exhaust pipe are arranged at the top of the cylinder body, the exhaust pipe is connected with a tail gas absorption tower, an exhaust fan is arranged on the exhaust pipe, an inner floating cover device is arranged above the liquid level in the cylinder body, the inner floating cover device is formed by a plurality of fan-shaped plates, small round inner connection plates and floating tubes. The fan-shaped plates are connected onto the outside of the small round inner connection plates in clamping mode in parallel to form the round flat plate shape. A floating tube is fixedly connected with the lower portion of each fan-shaped plate. The chlorine dioxide storage tank stores chlorine dioxide with high density, so that volatilization loss of the chlorine dioxide is minimum.
Description
Technical field
The utility model relates to chlorine dioxide storage facilities field, specifically a kind of chlorine dioxide storage tank with inner floating roof.
Background technology
Chlorine dioxide is a kind of strong oxidizer, and stable chlorine dioxide has been classified by the World Health Organigation (WHO) as the A1 level is efficient, the safe disinfection agent, also is good papermaking bleaching agent.From 1830s, begin to carry out suitability for industrialized production, in North America and Europe more than 1000 chlorine dioxide production factory arranged at present.
Chlorine dioxide is extremely unstable, heating or easily decomposition under illumination, and reaction equation is:
Because this reaction is the reaction that a gas molecula number increases, and is the chain reaction of heat release, so when its concentration was slightly high, because the increase of chain is very fast, volume can expand rapidly and set off an explosion.When its dividing potential drop surpasses 100mmHg (namely concentration reaches more than 14% under 1 barometric pressure), (temperature only need reach more than 45 ℃) will set off an explosion under irradiation or when heating, so its dividing potential drop of General Requirements can not surpass 100mmHg.This just determined chlorine dioxide can not resemble adopt compression or liquefaction other gas method caching in high pressure vessel, and, preparation or with the time also need to dilute with air or other unreactable gas such as nitrogen, carbon dioxide, require to make minute being pressed in below the 100mmHg of chlorine dioxide.
Chlorine dioxide is water-soluble, becomes yellow-green soln, and its solubility in water depends on the dividing potential drop of temperature and chlorine dioxide.Because the dividing potential drop of chlorine dioxide in gas phase generally can not surpass 100mmHg, at normal temperatures in the aqueous solution of chlorine dioxide concentration of chlorine dioxide below 10g/L, namely below 1%.And this solution is not only volatile, and also extreme difference of its chemical inertness, be heated by light and very easily decomposes, and has so just greatly limited the application of chlorine dioxide.Reduce the volatilization of chlorine dioxide by the transformation and optimization to the chlorine dioxide holding vessel, improve chlorine dioxide concentration, become common recognition.
The utility model content
Technical problem to be solved in the utility model provides a kind of chlorine dioxide volatilization that reduces, and improves the chlorine dioxide storage tank of concentration.
The utility model solves the problems of the technologies described above with following technical scheme:
The utility model is with the chlorine dioxide storage tank of inner floating roof, its tank body lower part is provided with the ClO 2 solution input duct, the tank body top is provided with explosion-proof covering board, pressure limiting hole and connects the freeing pipe of tail gas absorber, freeing pipe is provided with air suctiton ventilator, the liquid level top is provided with Inner Floating Roof Device in the tank body, Inner Floating Roof Device is made of fishplate bar and floating drum in polylith quadrant, the small circular, the outside side by side clamping several piece quadrant of fishplate bar is tabular to form circular flat in the small circular, and the below of every quadrant is connected with a floating drum.
The utility model is with the chlorine dioxide storage tank of inner floating roof, and described floating drum is arranged by the laterally radiation of tank body center.
The utility model is with the chlorine dioxide storage tank of inner floating roof, and described ClO 2 solution input duct stretches into the uniform hole, circular side that has on the interior pipeline of tank body.
The utility model is with the chlorine dioxide storage tank of inner floating roof, and fishplate bar and floating drum are made by the PVC resistant material in the quadrant of described Inner Floating Roof Device, the small circular.
The utility model is simple in structure, adopts the utility model to store chlorine dioxide, and its chlorine dioxide concentration is high, and it is minimum that air loss can reach.
Description of drawings
Fig. 1 is the structural representation of the utility model chlorine dioxide storage tank.
Fig. 2 is the schematic top plan view of Inner Floating Roof Device 5 among Fig. 1.
The specific embodiment
As shown in Figure 1 and Figure 2, tank body 1 bottom of storage chlorine dioxide is provided with ClO 2 solution input duct 7, and ClO 2 solution input duct 7 stretches into the uniform hole 6, circular side that has on the interior pipeline of tank body; The tank body top is provided with explosion-proof covering board 2, pressure limiting hole 4 and the freeing pipe 11 that connects tail gas absorber, freeing pipe 11 is provided with air suctiton ventilator 3, by with air suctiton ventilator 3 gas of tank top being pumped to tail gas absorber, be in micro-vacuum state in the holding tube, tank body 1 interior liquid level top is provided with Inner Floating Roof Device 5, Inner Floating Roof Device 5 is by polylith quadrant 8, fishplate bar 9 and floating drum 10 consist of in the small circular, fishplate bar 9 is spliced by three blocks of PVC plates in the small circular, its outer side edges quadrant 8 that clamping 12 block sizes are identical side by side is tabular to form circular flat, the below of every quadrant 8 is connected with a floating drum 10, several floating drums 10 are arranged by the laterally radiation of tank body center, the quadrant 8 of Inner Floating Roof Device, fishplate bar 9 and floating drum 10 are made by the PVC resistant material in the small circular.
During work, carry the high dense ClO 2 solution of coming to pass in the tank body 1 through input duct 7 from the absorption tower, diffuse into tank body behind the circular other hole 6 on the input duct 7, the impulse force when having disperseed ClO 2 solution to enter storage tank keeps the interior ClO 2 solution of tank stable.Along with ClO 2 solution in the storage tank is on the increase, Inner Floating Roof Device 5 constantly rises under the effect of buoyancy, and keeps Inner Floating Roof Device 5 to seal mutually with inner tank wall, reduces volatilization and the leakage of chlorine dioxide.The chlorine dioxide of a small amount of volatilization is sent into tail gas washing tower by air suctiton ventilator 3 extractions and is carried out double absorption.When the Inner Floating Roof Device 5 top pressure of tank body 1 inside too hour, a small amount of air just enters in the tank from pressure limiting hole 4, the balance inner and outer air pressure ensures safety in production.More when tank body 1 interior chlorine dioxide volatilization decomposition, when causing Inner Floating Roof Device 5 top pressure too large, explosion-proof covering board 2 can be upspring automatically, the balance external and internal pressure.
