Description
Technical field
This utility model relates to a kind of air cleaner, particularly to for the air cleaner between down-hole or mining area working environment Middle pressure draught fan and anti-dust respirator.
Background technology
At present, in down-hole or mining area working environment, operating personnel breathes air used, it purifies and mainly solves by system ventilation, namely at down-hole or mining area, pressure fan is installed to be pressed into by air, after decompressor reduces pressure, is connected to anti-dust respirator supply operating personnel's breathing of operating personnel either directly through rubber hose.
But, from the air that pressure fan is pressed into out, containing more impurity, abnormal flavour and moisture, it does not have directly feed operating personnel through purified treatment and breathe use, bring great hidden danger to the health of operating personnel. Therefore it provides a kind of air filtration and purification apparatus, it it is a problem demanding prompt solution.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of air filtration and purification apparatus, effectively purify and resupply down-hole after removing impurity contained from pressure fan air out, abnormal flavour and moisture and mining area operating personnel breathes, ensure the health of operating personnel.
The purpose of this utility model is achieved through the following technical solutions:
A kind of air filtration and purification apparatus, including interconnective coarse filter device and fine filtering apparatus, described coarse filter device is provided with air inlet and gas outlet, described gas outlet is connected to fine filtering apparatus, the gas outlet place of described coarse filter device is provided with one way pressure-reducing valve, and the outfan of described fine filtering apparatus is connected to anti-dust respirator by rubber tube. Gas pressure fan transported out by coarse filter device and fine filtering apparatus performs twice at effective purification, removes the impurity contained by gas, abnormal flavour and moisture. One way pressure-reducing valve had both played decompressing effect, was possible to prevent again gas backstreaming.
Preferably, described coarse filter device includes a main body vertically placed, the inner chamber of described main body is separated into left chamber and right chamber by dividing plate, described left chamber is connected with the lower end of right chamber, described left chamber upper end connects with air inlet, and described right chamber upper end connects with gas outlet, is placed with gaseous impurity adsorbent on the top of described left chamber and right chamber, bottom is placed with desiccant, described desiccant be arranged below screen cloth. Gas is by air inlet to the flow process of gas outlet, through twice gaseous impurity adsorption process and twice dry run, good purification in left chamber and right chamber.
Further, separated by screen cloth between described adsorbent and desiccant.
Further, described main body is arranged below outlet, and outlet is provided with valve. Outlet is easy to get rid of in time the moisture that desiccant absorbs, and closes valve and be possible to prevent air to overflow from water outlet after draining.
Preferably, described gaseous impurity adsorbent is activated carbon, and described desiccant is quick lime. Activated carbon and quick lime are common materials, draw materials easily, and with low cost.
Preferably, described fine filtering apparatus includes body and inside sets gradually curved pipe and check-valves, air flows through curved pipe and check-valves successively, and described curved pipe is internally provided with activated carbon. Curved pipe can increase the haul distance that air flows through, and increases the time of contact of air activated carbon, further up to the purpose purified. Check-valves is possible to prevent the gas backflow that operating personnel breathes out to enter in curved pipe.
Preferably, described curved pipe is serpentine shape or spiral-shaped.
The beneficial effects of the utility model: compared with prior art, the gas that pressure fan is transported out by this utility model by coarse filter device and fine filtering apparatus effectively purifies, resupply down-hole after removing the impurity contained by gas, abnormal flavour and moisture and mining area operating personnel breathes, ensure the health of operating personnel. This utility model simple in construction, easy to make, cost is low, it is simple to is promoting and application.
Accompanying drawing explanation
