Abstract
The utility model relates to a chemicals is respiratory device for reservoir, including a communicating pipe, communicating pipe's one end link up with reservoir, and the other end is the gas vent, the gas vent disposes the end cover that can open or close this gas vent, is being close to be provided with an air intake branch on the communicating pipe body of gas vent, filtration structure or filtration filler have been arranged in the air intake branch. As hazardous chemicals reservoir's breathing mouth, can in time release the pressure that produces in the container, perhaps, at the flowing back in -process or the container negative pressure that temperature fluctuations caused in because of the container, can prevent the dangerous condition to supplying uncontaminated air in the container.
Description
Technical field
The utility model relates to a kind of breather apparatus be arranged on chemical storage container, improves the safety in utilization of reservoir vessel.
Background technology
Chemical class storage container, especially there is certain danger in the storage of hazardous chemical category, such as hydrogen peroxide has slowly volatilization and decomposes depositing in process, and can heat be supervened in decomposable process, when the container inner pressure caused because of thermal release can not get timely release, maybe will set off an explosion Peril Incident.
In addition, in container discharge opeing process, the timely air inlet of container need makes up the container vacuum that discharge opeing causes, if pure air then need not process, when can be containing heavy metal in the air supplemented into, then the fission of hydrogen peroxide be probably caused to cause blast.
Utility model content
Technical problem to be solved in the utility model provides a kind of breather apparatus for above-mentioned prior art, be arranged on reservoir vessel, the reservoir vessel of especially dangerous liquid chemical, the pressure in container can be discharged in time, and, clean air can be supplemented in discharge opeing process, prevent dangerous situation in container.
The technical scheme in the invention for solving the above technical problem is: a kind of chemical storage container breather apparatus, comprise a connecting pipe road, one end and the reservoir vessel of described connecting pipe are through, the other end is exhausr port, described exhausr port is configured with the end cap that can open or close this exhausr port, connecting pipe body near described exhausr port is provided with an air intake branch, in described air intake branch, is furnished with air filtration structure or air filtration weighting material.
Preferably, described exhausr port is that angular cutouts can close described exhausr port in the mode of deadweight naturally to realize end cap, guarantees that end cap closes exhausr port all the time, entering of preventing pollution thing under non-exhaust decompression state.
Preferably, described air filtration weighting material is acticarbon, and active carbon can adsorb the impurity such as heavy metal, floating dust in air, purifies the air entered in container.
More conveniently arranging is that the corresponding mouth of pipe that described connecting pipe and reservoir vessel connect is designed to flange arrangement.
Usually, described connecting pipe is integrally moulded of PVC or PE, without metal parts, is particularly suited for the pneumostome in the reservoir vessel under the free pressure reservoir of chemical that is inflammable as major part, explosive, that have corrosion, carrys out the pressure inside and outside equalizing reservoir.
The principle of work of the chemical class reservoir vessel breather apparatus of said structure: when chemical liquid causes internal pressure higher than external pressure at reservoir vessel inside generation pressure, the end cap of exhaust ports is backed down, Exhaust Open, hold-off pressure.When container external and internal pressure reaches state of equilibrium, end cap is because close the state of exhausr port from recondition, prevent the pollutantss such as outside heavy metal and dust from entering in container by exhausr port, effectively prevention is brought out the chemical reaction of storage and causes the accident because pollutants enters in container.When chemical liquid discharge and the internal pressure that causes because of temperature traverse are lower than external pressure, air is by entering in container with the admission port of filtration or filtration pack, supplement the vacuum because negative pressure produces, through filtered air hardly with heavy metal and dust, eliminate potential safety hazard.
This device can be used alone, also can according to container size, store size and quantity that the pressure intensity of variation of chemical carry out selecting arrangement, the mode of Flange joint is more convenient for installation and repairing.
Come again, without the need to duty personnel when this device uses, as long as determine to change filtration pack as the frequency of activated carbon adsorbent according to the heavy metal and dust content that store place, within regular situation 3 ~ 6 months, change once.
Compared with prior art, the utility model has the advantage of: provide a kind of breather apparatus, for being arranged on dangerous chemical reservoir vessel, the pressure produced in container can be discharged in time; Or the container negative pressure caused in discharge opeing process or because of temperature fluctuation in container, can supplement clean air, prevent dangerous situation in container.

Fig. 2 is the birds-eye view of breather apparatus in the utility model embodiment;
Fig. 3 is the lateral plan of breather apparatus in the utility model embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
As shown in Figure 1 to Figure 3, chemical storage container breather apparatus in the present embodiment, comprises a connecting pipe road 1, and one end and the reservoir vessel of described connecting pipe 1 are through, and the corresponding mouth of pipe that connecting pipe 1 and reservoir vessel connect is designed to flange arrangement, be convenient to change, overhaul.The other end of connecting pipe 1 is exhausr port a, and exhausr port a is configured with the end cap 2 that can open or close this exhausr port, and exhausr port a is that angular cutouts can close this exhausr port a in the mode of deadweight naturally to realize end cap 2.Connecting pipe 1 body near exhausr port a is provided with an air intake branch 3, in air intake branch 3, is furnished with air filtration weighting material 4.
In the present embodiment, air filtration weighting material 4 is acticarbon, and acticarbon can adsorb the impurity such as heavy metal, floating dust in air, purifies the air entered in container.
Connecting pipe 1 is integrally moulded of PVC or PE, and without metal parts, not easily burn into not easily chemical reaction occurs, and is especially suitable as the pneumostome of the reservoir vessel under the free pressure reservoir of major part chemical that is inflammable, explosive, that have corrosion.
The principle of work of the chemical class reservoir vessel breather apparatus of said structure: when chemical liquid causes internal pressure higher than external pressure at reservoir vessel inside generation pressure, the end cap 2 at exhausr port a place is backed down, and exhausr port a opens, hold-off pressure.When container external and internal pressure reaches state of equilibrium, end cap 2 is because close the state of exhausr port a from recondition, prevent the pollutantss such as outside heavy metal and dust from entering in container by exhausr port a, effectively prevention is brought out the chemical reaction of storage and causes the accident because pollutants enters in container.When chemical liquid discharge and the internal pressure that causes because of temperature traverse are lower than external pressure, air is by entering in container with the admission port of filtration or filtration pack, supplement the vacuum because negative pressure produces, through filtered air hardly with heavy metal and dust, eliminate potential safety hazard.
In addition to the implementation, the utility model also includes other embodiments, the technical scheme that all employing equivalents or equivalent substitute mode are formed, within the protection domain that all should fall into the utility model claim.
