Description

A new type of micro-pollution water purification equipment

technical field

The utility model relates to a novel slightly polluted water purification device. It relates to a novel household micropollution water purification device.

Background technique

Nowadays, the drinking water of Chinese residents is mainly tap water, and some remote villages and towns may directly drink ground water or relatively clean surface water. Because tap water is susceptible to secondary pollution during water supply network transportation, groundwater and relatively clean surface water are easily affected by environmental pollutants, so the tap water, ground water and relatively clean surface water consumed by residents may become micro-polluted water. Slightly polluted water often contains heavy metal ions such as manganese, zinc, aluminum, and lead, as well as harmful substances such as rust, residual chlorine, and a large number of microorganisms. If these slightly polluted water is directly drunk by residents, the harmful substances in the water can cause residents to suffer from diarrhea, abdominal distension, coma and convulsions, etc. Long-term drinking may even cause residents to suffer from diseases such as liver cancer or kidney cancer. In addition, attention should be drawn to the fact that residents’ health will also be affected when bathing in slightly polluted water; bathing in a closed bathroom will produce a large amount of water vapor, and harmful substances such as residual chlorine and heavy metals in the water vapor will be released with time. As the temperature of the bath water increases, the concentration increases, and they can be quickly absorbed by the human body through the expansion of sweat pores; the harmful substances absorbed by the body of residents once bathed are often several times higher than the usual intake of drinking water , or even dozens of times; these harmful substances will not only make the skin dry, itchy, and hair loss, but more seriously, the capillaries will lose their elasticity. Therefore, it is urgent to remove harmful substances such as heavy metal ions, microorganisms and residual chlorine in household slightly polluted water, to ensure the safety of residents' bathing water and drinking water, and to comprehensively improve the quality of life of residents. At present, household water purifiers basically only provide purified drinking water, but not safe and high-quality bathing water, and there are usually multiple filter tubes in the current water purifier, and when the treated water flows through each filter tube in turn The pollutants in it are removed by contacting with the filter material (mainly activated carbon); the filter tube of this filtration process is long, and the filter tube is required to be filled with enough filter material to ensure that the treated water has sufficient contact with the filter material ; This leads to problems such as large consumption of filter material, easy waste, frequent replacement, and high purification cost in household water purifiers. Therefore, it is of great practical significance to develop a new type of micro-polluted water purification equipment to effectively remove pollutants in micro-polluted water, reduce the cost of equipment filter materials, and achieve quality water supply for drinking water and bathing water.

A new micro-polluted water purification equipment process of the present utility model, the process includes a preliminary purification stage, a deep filtration and classified storage stage, and a drinking water repurification stage; through the combined application of these three stages, a new type of purification process of the present utility model can be realized The effective treatment of micro-polluted water by micro-polluted water purification equipment and the purpose of providing drinking water and bathing water quality water supply. In the initial purification stage, the initial purification stage of the equipment is carried out by the combination of a new type of circulating filtration method and a microwave non-polar ultraviolet light method; after the slightly polluted water is filled with the turnover water tank, it starts to flow and flows through the natural zeolite filter tube, silicon carbon doped The hydroxyapatite filter tube flows back to the turnover water tank through the connecting pipe, completes a filtration, and then flows out from the turnover water tank and flows through the natural zeolite filter tube, the silicon-doped hydroxyapatite filter tube, and the flow through the connecting pipeline. Return to the turnover water tank to complete another filtration, and then complete the rest of the cyclic filtration process depending on the water quality of the slightly polluted water; during this cyclic filtration process, the microwave electrodeless ultraviolet lamp is turned on at the right time, and the slightly polluted water is always in the ultraviolet sterilization environment; preliminary After the purification stage, the microbial removal rate in the slightly polluted water is as high as 99.9%, and the heavy metal content is also greatly reduced (iron<2mg/L, manganese<0.05mg/L, lead removal rate is over 99%); the slightly polluted water is purified after this stage It can be directly used as bathing water, or as source water for in-depth filtration treatment for the subsequent provision of drinking water for residents; under normal circumstances, the initially purified slightly polluted water has reached the standard for bathing water, and the preliminary purification detected by the water quality probe I When the water meets the bathing water standard requirements, it can be used directly as bathing water, or as source water for deep filtration treatment for the subsequent supply of drinking water for residents; however, if the initial purification stage lasts for 10 minutes or more, the water quality probe I will detect If the preliminary purified water has not reached the bathing water standard, the signal will be sent to the PLC, and the PLC will issue a warning requesting people to replace the fillers in the natural zeolite filter tubes and silicon-doped carbon hydroxyapatite filter tubes or for the microwave electrodeless ultraviolet lamp Wait for other equipment to be overhauled (regular maintenance of equipment, generally this will not happen). In the stage of deep filtration and classified storage, after the preliminary purification stage, the PLC controls the electromagnetic valve b and the microwave electrodeless ultraviolet lamp to close; the water after preliminary purification has two storage places: bathing water storage tank and drinking water storage tank; when bathing water When the water storage tank is short of water, the pressure (P2) measured by the water pressure sensing device of the bathing water storage tank is less than the minimum value (P2min) of the specified water pressure range limit, the PLC will open the electromagnetic valve c, start the water pump, and the water after preliminary purification The water enters the bath water storage tank driven by the water pump; when the bath water storage tank is full, the pressure (P2) measured by the bath water storage tank water pressure sensing device is greater than the maximum value (P2max) of the specified water pressure range limit , the PLC will close the electromagnetic valve c and the water pump; the use of pre-purified water can effectively avoid the damage of residual chlorine and heavy metals in micro-polluted water to the human body through the pores of the skin, ensuring the health of residents and improving the quality of life of residents. When the drinking water storage tank is short of water, the pressure (P1) measured by the water pressure sensing device of the drinking water storage tank is less than the minimum value (P1min) of the specified water pressure range limit, the PLC will open the electromagnetic valve d to start the water pump, after preliminary purification Driven by the water pump, the water flows into the drinking water storage tank through the viscose-based activated carbon fiber filter tube and becomes deeply purified water; under normal circumstances, the deeply purified water has reached the standard of drinking water, and the deeply purified water detected by the water quality probe II has reached the level of drinking water. When the water standard requires, it can be used as drinking water (it can be used as drinking water and kitchen water); but if the deeply purified water detected by the water quality probe II does not meet the standard of drinking water, the signal will be sent to the PLC, and the PLC will give a warning to ask people Replace the filler in the viscose-based activated carbon fiber filter tube or perform other equipment maintenance (regular maintenance of equipment, generally this situation will not occur); when the drinking water storage tank is full, the water pressure sensing device of the drinking water storage tank will measure If the pressure (P1) is greater than the maximum value (P1max) of the specified water pressure range limit, the PLC controls the water pump to stop running, and closes the electromagnetic valve d, and the equipment enters the standby state to reduce energy consumption. When the bathing water storage tank and the drinking water storage tank are short of water at the same time, the PLC defaults to give priority to water supply to the drinking water storage tank. Viscose-based activated carbon fiber is fibrous activated carbon, which is the third generation of new carbonaceous functional adsorption material after powdery and granular activated carbon; viscose-based activated carbon fiber woven from cellulose has a large specific surface area, rich micropores and Narrow distribution, easy contact with adsorbate, fast adsorption rate, single structure, good toughness, good biocompatibility, low cost and no toxic side effects, but it has the disadvantages of relatively expensive and complicated regeneration. Placing the viscose-based activated carbon fiber filter tube after circulation filtration can not only deeply purify the primary purified water flowing through, remove a small amount of residual pollutants in the primary purified water, and ensure the quality of drinking water, but also due to micro-pollution After the water is purified many times in the circulating filtration stage, the content of harmful substances in the water is reduced, so the service life of the activated carbon fiber is greatly extended and the use cost is saved. In the drinking water repurification stage, when the deeply purified water (drinking water) stored in the drinking water storage tank has not been used for 12 hours, the PLC will automatically open the electromagnetic valve f, and the deeply purified water in the drinking water storage tank is Under the action of gravity, it flows into the turnover water tank; after the deeply purified water (drinking water) in the drinking water storage tank flows into the turnover water tank, the pressure (P3) in the turnover water tank measured by the water pressure sensing device of the turnover water tank will be greater than the specified water pressure range The maximum value of the limit (P3max), the PLC will close the electromagnetic valve f, start the water pump, and the equipment will re-purify and filter the deeply purified water; but when the electromagnetic valve a has not been opened for more than 24 hours, that is, the re-purified water When the drinking water is stored again in the drinking water storage tank for more than 12 hours, the PLC will directly open the electromagnetic valve g, so that the drinking water flows into the bathing water storage tank as the reserve water for washing and bathing.

The utility model relates to a novel micro-polluted water purification equipment process, which includes a preliminary purification stage, a deep filtration and classified storage stage, and a drinking water repurification stage. In the initial purification stage, the initial purification stage of the equipment adopts a new type of circulation filtration method combined with a microwave stepless ultraviolet light method, which can initially remove harmful substances in slightly polluted water (including heavy metal ions such as manganese, zinc, aluminum, lead, rust, residual chlorine and microorganisms, etc.). The circulating filtration method is to make the slightly polluted water circulate with the water in the filter tube when it circulates between the turnover water tank (2), the natural zeolite filter tube (5) and the silicon-doped carbon hydroxyapatite filter tube (6) of the utility model equipment. The filter material is in constant contact, and harmful substances (including manganese, zinc, aluminum, lead and other heavy metal ions, rust, residual chlorine, etc.) are continuously absorbed and filtered by the filter material to remove harmful substances in micro-polluted water; During the circulating filtration period, the PLC (20) will turn on the microwave electrodeless ultraviolet lamp (4) in good time to irradiate the slightly polluted water, so as to kill and remove microorganisms. The combined application of the new circulating filtration method and microwave stepless ultraviolet light method can preliminarily remove harmful substances in slightly polluted water (including heavy metal ions such as manganese, zinc, aluminum, lead, rust, residual chlorine and microorganisms, etc.). The specific equipment operation process at this stage is as follows: press the start button (32) on the PLC (20) to start the equipment, and the slightly polluted water flows into the turnover water tank (2) through the water inlet pipe 1 (26). When the slightly polluted water is full of the turnover water tank (2), the internal pressure (P3) of the turnover water tank (2) measured by the water pressure sensing device (3) of the turnover water tank will be greater than the maximum value (P3max) of the specified water pressure range limit, and the PLC (20) will close the electromagnetic valve a(1), open the electromagnetic valve b(8), and start the water pump (7) and the microwave electrodeless ultraviolet lamp (4); due to the rapid rotation of the impeller of the water pump (7), the slightly polluted water starts to flow and flows through the natural zeolite in turn The filter tube (5), the silicon-doped carbon hydroxyapatite filter tube (6), flow back to the turnover water tank (2) through the connecting pipe, complete a filtration, and then flow out from the turnover water tank (2) and flow through the natural The zeolite filter tube (5), the silicon-doped carbon hydroxyapatite filter tube (6), flow back to the turnover water tank (2) through the connecting pipe, and complete another filtration, and then complete the remaining circulating filtration depending on the water quality of the slightly polluted water process, when the preliminary purified water detected by the water quality probe I (33) meets the preset bath water standard requirements, the electromagnetic valve b (8) is closed to stop the circulation filtration process; during this circulation filtration process, the microwave electrodeless ultraviolet lamp (4 ) is turned on, and the slightly polluted water is always in the ultraviolet sterilization environment.

When the water pollution degree of the slightly polluted water is slightly higher, the PLC prolongs the filtering time and the circulating filtering process time is slightly extended; but when the circulating filtering time exceeds 10 minutes, the water quality probe I ( 33) When the detected preliminary purified water still does not meet the water quality requirements, the signal will be sent to the PLC (20), and the PLC (20) will give a warning to ask people to replace the natural zeolite filter tube (5) and silicon-doped carbon hydroxyapatite filter Filling in the tube (6) or maintenance of other equipment such as the microwave electrodeless ultraviolet lamp (4) (the equipment is regularly maintained, and this situation generally does not occur); after the preliminary purification stage, the microbial removal rate in the slightly polluted water is as high as 99.9% , the content of heavy metals is also greatly reduced (iron<2mg/L, manganese<0.05mg/L, lead removal rate above 99%); after this stage of purification, the slightly polluted water can be directly used as bathing water or as a follow-up supply for residents Source water for deep filtration treatment of drinking water.

In the stage of deep filtration and classified storage, after the preliminary purification stage, the PLC (20) controls the solenoid valve b (8) and the microwave electrodeless ultraviolet lamp (4) to close; the water after preliminary purification has two storage places: the bath water storage tank (17) and drinking water storage tank (13); when the bathing water storage tank (17) was short of water, the pressure (P2) measured by the bathing water storage tank water pressure sensing device (18) was less than the specified water pressure range limit value Minimum value (P2min), PLC (20) will open electromagnetic valve c (9), start water pump (7), and the water after preliminary purification enters bathing water storage tank (17) under the drive of water pump (7); When the water storage tank (17) is filled up, the pressure (P2) measured by the water pressure sensing device (18) of the bath water storage tank (18) is greater than the maximum value (P2max) of the specified water pressure range limit, and the PLC (20) will turn off the electromagnetic Valve c (9) and water pump (7); the use of pre-purified water can effectively avoid the damage of residual chlorine and heavy metals in micro-polluted water to the human body through the pores of the skin, ensuring the health of residents and improving the quality of life of residents . When the drinking water storage tank (12) is short of water, the pressure (P1) measured by the water pressure sensing device (13) of the drinking water storage tank (13) is less than the minimum value (P1min) of the specified water pressure range limit, and the PLC (20) will open The electromagnetic valve d (10) starts the water pump (7), and the preliminarily purified water flows into the drinking water storage tank (12) after being driven by the water pump (7) through the viscose-based activated carbon fiber filter tube (11) to become deeply purified water Under normal circumstances, the deeply purified water has reached the standard of drinking water, and when the deeply purified water detected by the water quality probe II (34) reaches the requirements of the drinking water standard, it can be eaten as drinking water; but if the water quality probe II (34) detects If the deeply purified water does not reach the standard of drinking water, then the signal will be sent to PLC (20), and PLC (20) will give a warning to require people to replace the filler in the viscose-based activated carbon fiber filter tube (11) or do other equipment maintenance; When the water storage tank (12) is filled up, the pressure (P1) measured by the water pressure sensing device (13) of the drinking water storage tank (13) is greater than the maximum value (P1max) of the specified water pressure range limit, and the PLC (20) controls the water pump ( 7) Stop running, and close the electromagnetic valve d (10), and at the same time, the equipment enters a standby state to reduce energy consumption. When the bathing water storage tank (17) and the drinking water storage tank (13) were short of water simultaneously, the PLC (20) defaulted to giving priority to the water supply to the drinking water storage tank (12); It is necessary to manually change the priority water supply sequence. Viscose-based activated carbon fiber is fibrous activated carbon, which is the third generation of new carbonaceous functional adsorption material after powdery and granular activated carbon; viscose-based activated carbon fiber woven from cellulose has a large specific surface area, rich micropores and Narrow distribution, easy contact with adsorbate, fast adsorption rate, single structure, good toughness, good biocompatibility, low cost and no toxic side effects, but it has the disadvantages of relatively expensive and complex regeneration. Placing the viscose-based activated carbon fiber filter tube (11) after circulating filtration can not only carry out deep purification of the water after preliminary purification, remove a small amount of residual pollutants in the water after preliminary purification, and ensure the quality of drinking water, but also Since the micro-polluted water has been purified many times in the circulating filtration stage, the content of harmful substances in the water is reduced, so the service life of the activated carbon fiber is greatly extended and the use cost is saved.

In the drinking water repurification stage, when the electromagnetic valve d (10) has not been opened for more than 12 hours, that is, when the deeply purified water (drinking water) stored in the drinking water storage tank (12) has not been used for 12 hours, the PLC (20) The electromagnetic valve f (15) will be opened automatically, and the water after the depth purification in the drinking water storage tank (12) flows into the turnover water tank (2) under the effect of gravity; the water after the depth purification in the drinking water storage tank (12) After all (drinking water) flows into the turnover water tank (2), the pressure (P3) in the turnover water tank (2) measured by the turnover water tank water pressure sensing device (3) will be greater than the maximum value (P3max) of the specified water pressure range limit, PLC (20) will close the electromagnetic valve f (15), start the water pump (7), and the equipment will perform preliminary purification and advanced filtration on the water after deep purification; but when the electromagnetic valve a (1) has not been opened for more than 24 hours, it will restart When the purified drinking water is stored again in the drinking water storage tank (12) for more than 12 hours, the PLC (20) will directly open the electromagnetic valve in order to prevent the microorganisms in the drinking water from being irradiated by ultraviolet rays for multiple times to cause genetic mutations and cause harm. g (16), drinking water is made to flow into the bathing water storage tank (17) as the reserve water for washing and bathing.
