Description

A device for collecting scattered mercury beads

technical field

The utility model belongs to the field of cleaning devices, in particular to a collecting device for scattered mercury beads.

Background technique

Although electronic thermometers and electronic sphygmomanometers have been used to a certain extent, mercury (mercury) thermometers and mercury sphygmomanometers are the most common, economical, and accurate for low temperature and blood pressure tests in homes and hospitals. During use, due to carelessness or aging, these mercury-containing products will be broken, and the mercury will flow out to the ground. Mercury does not infiltrate many surfaces such as wooden floors and concrete floors. In addition, due to the high surface tension, the leaked mercury will form a large number of mercury beads on the ground. Mercury is the only metal that is liquid at room temperature and has a very high density of 91.5 _g /cm ³ , which is 91.5 times that of water. Mercury beads in motion have high inertia and will be scattered around under the action of inertia and gravity. Mercury has a large vapor pressure at room temperature, and after being broken into a large number of mercury beads, the specific surface area increases, and it will continue to volatilize into the air until it reaches its saturation concentration at this temperature. Studies have shown that mercury, as a heavy metal element, has high toxicity and its vapor can enter the human body through inhalation and skin, damage the respiratory system and nervous system, and even cause death in severe cases. If the mercury beads are not treated in time, they will eventually completely volatilize and become mercury vapor, which will eventually enter the atmosphere during the ventilation process. On January 1, 2091, the United Nations Environment Program adopted the Minamata Convention, an international convention aimed at controlling and reducing mercury emissions on a global scale. damage. Mercury entering the atmosphere will eventually endanger human health through processes such as dry and wet deposition, methylation, and food chain accumulation.

In summary, scattered mercury beads must be collected immediately and properly sealed before being disposed of as hazardous solid waste. If you use common cleaning tools such as brooms commonly used in households for cleaning, the larger mercury beads will be further broken into fine mercury beads and enter the crevices, and the open environment and larger surface area will cause faster evaporation of mercury . If it is collected with a vacuum cleaner, it will be easier to suck away the mercury beads in the gaps, etc., but during the suction process, it will be pneumatically broken to produce a large number of fine mercury beads and mercury vapor, which will pass through the filter of the vacuum cleaner and be discharged into the indoor air. cause more serious pollution.

As shown in Figure 1, a kind of collecting device of scattered mercury beads comprises shell 1, and described shell 1 is provided with cyclone separator 2, and cyclone separator 2 is provided with air inlet 21, air outlet 22 and ash outlet 23. The air inlet 21 of the cyclone separator 2 is equipped with an air inlet pipe 3 for connecting with the suction nozzle of the vacuum cleaner. The ash outlet 23 of the cyclone separator 2 is connected with a mercury discharge pipe 4, and the other end of the mercury discharge pipe 4 is The mercury bead collection bottle 5 is connected, and the air outlet 22 of the cyclone separator 2 is connected with a mercury vapor adsorption filter 6, which includes a tank body 61, which is provided with a suction hose for connecting with a vacuum cleaner. The connected air outlet pipe 9, the air intake pipe 3, the mercury discharge pipe 4 and the air outlet pipe 9 all pass through the shell 1, and the tank body 61 is provided with an adsorption filter body 7 for adsorbing mercury vapor. The adsorption filter body 7 includes a grid frame and a The cotton wool on the net frame contains mercury-removing activated carbon. The tank body 61 includes an upper tank body and a lower tank body, the upper tank body is detachably connected to the lower tank body, so as to place the adsorption filter body 7 therein.

Preferably, the adsorption filter body 7 is provided with multiple layers to ensure that the mercury vapor is completely absorbed. Because this product is a household type, the amount of mercury in household electronic thermometers or electronic sphygmomanometers is generally not large, so several layers of adsorption filters 7 can be arranged to ensure that the mercury vapor is completely absorbed.

The inner cavity of the part where the air outlet pipe 9 extends out of the shell 1 is provided with metallic mercury color-developing paper 8, and there is elemental sulfur reagent on the metal mercury color-developing paper 8, which can absorb mercury vapor. The air outlet pipe 9 is provided with an observation hole 91 for observing the color change of the metal mercury color paper 8, through which the color change of the metal mercury color paper 8 can be used to confirm whether the mercury vapor is completely absorbed. Color paper 8 can turn black, therefore, metallic mercury color paper 8 can continue to absorb mercury vapor again again.

In addition, an extension pipe 92 is installed at the observation hole 91 of the air outlet pipe 9, and an observation glass 93 is installed in the extension pipe 92. The setting of the observation glass 93 is not only convenient for observing the color of the metallic mercury color paper 8, but also can be used for observation. Hole 91 is sealed to prevent mercury vapor from leaking.

The casing 1 includes an upper casing 11 and a lower casing 12 , and the upper casing 11 is detachably connected to the lower casing 12 so as to put the cyclone separator 2 and the mercury vapor adsorption filter 6 into the casing 1 .

The main function of the collecting device is to collect mercury beads and adsorb mercury vapor.

Mercury bead collection is mainly realized by cyclone separator 2 and mercury bead collecting bottle 5 . When the vacuum cleaner is working, the mercury beads are inhaled from the suction nozzle of the vacuum cleaner and enter the cyclone separator 2 through the air intake pipe 3. Because the mercury beads are in liquid state, they will be separated from the gas in the cyclone separator 2. Under the action of gravity, the mercury beads fall Into the mercury bead collection bottle 5. The mercury bead collection bottle 5 is detachably connected to the mercury discharge pipe 4. After the treatment is completed, the mercury bead collection bottle 5 is removed, and then the mouth of the mercury bead collection bottle 5 is sealed with a sealing plug, and then put into the mercury-containing waste for sealing. bag.
