Description

A kind ofly be applicable to the unpowered emergent water purifier shaking rear disaster area
Technical field
The invention belongs to water-treatment technology field, be specifically related to a kind of unpowered emergent water purifier being applicable to shake rear disaster area.
Background technology
After earthquake, the water-supply systems of severely afflicated area are in complete state of paralysis substantially, and the waterworks of surrounding cities also can be subject to damage in various degree.Emergency works repairing work often needs time a couple of days, stop leakage in the roof rush to repair impaired water supply line process in, how to be even more important for the victims of the disaster provide water facilities or tap water to seem temporarily.
The safe drinking water of earthquake-stricken area lacks problem to be caused primarily of following three reasons.
(1) earthquake causes original running water pipe explosion, damages thus waterworks is paralysed.
(2), in seismic process, a large amount of magazine that causes of large-area building collapsing and rubble flow outflows;
(3) road traffic suffers great destruction, makes relief goods be difficult to send to disaster area in time and cannot supply water to disaster area continuously simultaneously.
Earthquake-stricken area drinking water safety emergency water supply measure mainly contains bottled water, waterwheel send water, dispersion water intaking three kinds of emergency schedules.But bottled water cost is high, transport difficult, waterwheel is by road conditions restriction finite capacity, and the water quality safety of dispersion water intaking can not ensure completely.Therefore, these emergency water supply measures all have some limitations, can not be complementary well.
After earthquake, the suspended solids in water source, colloid, dissolved organic matter, microorganism etc. can increase relatively, therefore, rational filtering and cleaning technique must be adopted to ensure effluent quality safety.The water purification product that can be applicable to earthquake-stricken area in the market has following several:
(1) " life suction pipe " (lifestraw)
This kind of product is the outdoor water purifier be made up of yarn fabric, iodine, gac, and advantage is that volume is little, portable, and shortcoming only relies on iodine to kill bacteriophage, and effluent quality is difficult to ensure.
(2) emergent water purifying plant
The reverse osmosis water purifying plant provided for disaster area by water purification company, self-powered, but quality is comparatively large, and advantage is that effluent quality is good, and shortcoming is transport difficult.
(3) filer element type water purifier
What this water purifier adopted is filter cartridge construction, and according to different demands, different filter core of can arranging in pairs or groups, advantage is that price comparison is cheap, and shortcoming is that filter element life is shorter, and cleaning water is lower.
Summary of the invention
The object of the invention is to provide a kind of tap water problem both solving the victims of the disaster by purification water source, disaster area, does not need power consumption again, and conveniently transports the unpowered emergent water purifier carried.
What the present invention proposed is applicable to the unpowered emergent water purifier shaking rear disaster area, comprises pressure pot 2, inflator pump 1, micro-filtration web filter 5 and film filter 8, wherein:

Embodiment
The present invention is further illustrated by reference to the accompanying drawings below by embodiment.
Embodiment 1: as shown in Figure 1, described device is connected to form by pipeline and valve by pressure pot, inflator pump, micro-filtration web filter and film filter, wherein:
Inflator pump 1 is cylindrical, is made up of pull bar, plastic casing and escape pipe, and the mouth of pipe of escape pipe is connected with the inlet pipe at the top of pressure pot 2;
Pressure pot 2 is in elliposoidal, be connected by plastic casing, plastic roof, inlet pipe and rising pipe 3, it is inner that inlet pipe enters pressure pot 2 through plastic roof, and it is inner that rising pipe 3 gos deep into pressure pot 2 by plastic roof, leaves a part of gap bottom rising pipe 3 bottom the mouth of pipe and pressure pot 2;
Micro-filtration web filter 5 top is cylindrical, bottom is truncated cone-shaped, be made up of micro-filtration net filter core 6, back flush valves 11 and metal shell, water inlet pipe and rising pipe lay respectively at left end and the right-hand member of strainer 5, micro-filtration net filter core 6 is positioned at middle part, be connected with the top of metal shell, its right-hand member is connected to rising pipe, and back flush valves 11 is positioned at the bottom of metal shell;
Film filter 8 is cylindrical, and be made up of hollow-fibre membrane 9, outfall sewer 10 and stainless steel casing, hollow-fibre membrane 9 is fixed on the top of film filter 8, and is connected with rising pipe 10, leaves certain space between stainless steel casing and hollow-fibre membrane 9.
The operation of this device can be divided into raw water filtration and back flushing two processes:
(1) raw water filtration
Pressure pot 2 is one in the plastic cylinder of elliposoidal, and it is inner that inlet pipe enters pressure pot 2 through plastic roof, and it is inner that rising pipe 3 gos deep into pressure pot 2 by plastic roof.During operation, open the plastic roof on top, can pour in pressure pot 2 in the past former water to be filtered with, add appropriate Powdered Activated Carbon, in bucket, former water answers the bottom mouth of pipe of submergence rising pipe 3 simultaneously.Promote the pull bar of inflator pump 1, gas compression is inner to pressure pot 2, and barrel internal gas pressure is increased, and the pressure reduction formed makes the former water in pressure pot 2 be flowed out by rising pipe 3.Opened filter inlet valve 4, former water enters micro-filtration web filter 5.The operation scheme of micro-filtration web filter 5 is left end water inlet, right-hand member water outlet.Current flow into rising pipe water outlet after the filtration of micro-filtration net filter core 6.Micro-filtration net filter core 6 can retain the Powdered Activated Carbon in current, forms layer of active carbon inverted filter, removes the most of particulate matter in water.Opened filter inlet valve 7, current enter film filter 8, utilize pressure reduction, current carry out ultrafiltration by hollow-fibre membrane 9, the macromolecular substance such as the colloid in water, bacterium, virus can be removed, by the last water outlet of outfall sewer 10 after ultra filtration, complete whole Water treatment.
(2) cleaning of device
When filtration is constantly carried out, Powdered Activated Carbon and impurities in water are also constantly trapped in micro-filtration net filter core 6 surface by Cumulate Sum, affect the discharge capacity of micro-filtration web filter 5.Therefore, suitably should clean according to service condition.During cleaning, the shell of micro-filtration web filter 5 is screwed off, micro-filtration net filter core 6 is placed in bucket and cleans; In addition, the upper casing of film filter 8 is screwed off, simply rinse with the clear water after filtering.
