Abstract

A disinfecting and cleaning system for the inner surface of water pipeline in building is disclosed, and features the use of ozone. The ozone pipeline of ozone generator has check valve, ozone feading outlet and ozone drive out port. A venturi tube is arranged between the said ozone feeding outlet and building. The ozone is mixed with water to generate a lot of air bubbles and very high pressure, which can remove the deposit and dregs on the inner surface of water pipeline and eliminate the bacteria and viruses.

Description

System for disinfecting and cleaning inner wall of water pipe by using ozone and air bubbles

The invention belongs to a water pipe disinfecting and cleaning system.

At present, after the cold and hot water pipes and heating pipelines of buildings such as apartments, office buildings, houses, factories and the like are used for a period of time, bacteria, deposited water scales and the like can grow in the water pipes, and the water pipes are gradually attached to the inner walls of the water pipes and corrode the pipelines, so that the water quality is influenced, the smoothness of water flow is hindered, and inconvenience is brought to the health and life of people.

The invention aims to disinfect and clean cold and hot water pipes and heating pipelines of buildings such as apartment office buildings, houses, factories and the like by injecting ozone and air bubbles into water pipes, remove stink, bacteria and viruses generated in the pipelines, remove sediments and residues of the stink, the bacteria and the viruses, and provide clean water resources for people.

The present invention is characterized in that check valves 11, 11a and ozone pushing outlets 7, 7a are provided in ozone pipes 10, 10a between an ozone generator 2 and ozone inlets 8, 8a,

venturi tubes

13, 13a are provided in a cold water pipe 5 and a hot water pipe 6 between the ozone inlets 8, 8a and a building 1, a check valve 11b is provided between the venturi tube 13a on the hot water pipe 6 and a boiler 12, and the boiler 12 is communicated with an underground water storage tank 3.

The invention is further described below:

the underground of the building 1 is an underground water storage tank 3, the roof is an upper water storage tank 4, an ozone generator 2 is arranged at a proper position, and ozone generated by the ozone generator 2 is added into a cold water pipeline 5 and a hot water pipeline 6 through ozone input ports 8 and 8 a.

In the ozone pipes 10 and 10a, ozone can be diffused in the cold water pipe 5 and the hot water pipe 6 through check valves 11 and 11a, ozone push-out ports 7 and 7a, ozone input ports 8 and 8a, and

venturi tubes

13 and 13a, and a large amount of air bubbles can be input in the process, motor pumps 9 and 9a capable of smoothly flowing water are installed in the upper water storage tank 4 and the underground water storage tank 3, a boiler 12 supplies hot water to the hot water pipe 6, and a check valve 11b is installed between the boiler 12 and the venturi tube 13 a.

The invention has the advantages that the ozone and the air bubbles are adopted to disinfect and clean cold and hot water pipes and heating pipelines of buildings such as apartments, office buildings, houses, factories and the like, so as to remove stink, bacteria and viruses generated in the pipelines and remove sediments and residues of the pipelines, thereby ensuring clean water supply and smooth water channels.

The attached drawing is a connection system of the present invention.

Wherein, 1 building, 2 ozone generator, 3 underground water storage tank, 4 upper water storage tank, 5 cold water pipeline, 6 hot water pipeline, 7a ozone push outlet, 8a ozone input port, 9a motor pump, 10a ozone pipeline, 11a, 11b check valve, 12 boiler, 13a venturi tube, 14 outlet, 15 water tank connecting pipe.

Embodiments of the invention are provided below with reference to the accompanying drawings:

venturi tubes

The underground water storage tank 3 under the ground of the building 1 is connected to a hot water pipe 6 via a motor pump 9a, a boiler 12, and a check valve 11b, an ozone inlet 8a is connected to the hot water pipe 6, and ozone generated by the ozone generator 2 is injected into the ozone inlet 8a via an ozone pipe 10a, a check valve 11a, an ozone outlet 7a, and a venturi tube 13a to form air bubbles at the ozone inlet 8a, and the air bubbles are injected at a very high pressure. In addition, in the cold water pipe 5 connected to the motor pump 9 in front of the upper water storage tank 4 installed on the roof of the building 1, ozone generated from the ozone generator 2 passes through the ozone pipe 10, the check valve 11, and the ozone outlet 7, and air bubbles are formed at the ozone inlet 8 and the venturi tube 13 and are introduced into the ozone inlet.

Ozone injected into the cold water pipe 5 and the hot water pipe 6 is diffused at a very high pressure when passing through the

venturi tubes

13 and 13a between the ozone push-out ports 7 and 7a and the cold and

hot water pipes

5 and 6, and is injected into the ozone push-out ports so as to be easily mixed with water and hit the inner walls of the cold and

hot water pipes

5 and 6, thereby strongly pushing the residue forward. In this state, the drain port 14 of the building 1 is opened, and ozone water is supplied at a concentration of about 10PPM, and after about 20 minutes, red-black floating matter is generated, and after 30 to 40 minutes, the outflow of clear water is confirmed, and then ozone water at a concentration of 1PPM is supplied.

The disinfection and cleaning principle of the invention is described as follows from the chemical point of view:

ozone O₃The molecular weight was 48, the melting point was-251.5 ℃, the boiling point was-11.2 ℃ and the weight was 1.7. The structure of ozone is equilateral triangle, its binding force is very weak, in three atoms, the 3 rd atom is very easy to decompose, can form the foul smellCompared with chlorine and hydrogen peroxide, the oxygen of the oxygen generator has the characteristics of extremely strong oxidizing power and no bacteria residue effect compared with ozone, can remove various bacteria such as stink, bacteria and viruses in a water pipeline, removes sediments and prevents corrosion.

Addition of iron (raw Rust iron) Fe (OH) to water₂Injecting ozone O₃The following reaction takes place:

at this time, if 12Fe (OH) is reduced₃Temporarily changed to 6Fe₂O₃Later on, automatically become 4Fe₃O₄And (3) not only:

primary reduction: 6Fe₂O₃+66H₂O+15O₂

And (3) secondary reduction: 4Fe₃O₄+66H₂O+16O₂

The reduced product Fe₃O₄The bonding performance of the composite material is very strong, other reactions cannot be generated, and a film is formed on the pipe wall to play a role in corrosion prevention.

The causes of deposits and bacteria in water pipes vary with the attachment of organisms and the environment. Organic matter and bacteria are easy to concentrate and combine, the bacteria adhered to the surface of the solid are multiplied by a certain inducement, and if the bacteria are inhibited in a sprouting state, biological attachment can be eliminated; if the water contains iron and manganese, odor can be generated and the water is colored, in this case, the water channel is easily closed and is red due to the increase of bacteria in the water channel, and the manganese is bitter, so the flow of the pipeline is reduced.
