Description

The present invention automatically decomposes and filters carbon monoxide and other toxins contained in the exhaust gas discharged from the gas water heater, and discharges them after being filtered, preventing users from becoming addicted to inappropriate use. It relates to a device that can.

Accidents in which an ordinary person died from carbon monoxide poisoning using a water heater is because the water heater is installed indoors or the water heater is installed on the veranda, but the aluminum fence or indoor window attached to the veranda is closed or the veranda is installed. This is because there is too much clothing on the bed and the flow of air becomes poor and the water heater causes incomplete combustion, and the carbon monoxide concentration in the room becomes too high, resulting in poisoning. However, in a small house in an urban environment, there is a space limitation and a gas water heater must be installed indoors. Therefore, an indoor gas water heater that exhausts exhaust gas forcibly must be selected. I must. However, although the room-use gas water heater has a function of forcibly exhausting the exhaust gas, if the gas water heater is installed in the room, exhaust gas exhaustion or carbon monoxide leaks 100%. There is no guarantee that it will not happen, and even if carbon monoxide leaks once, important human lives may be lost.

Therefore, the present invention provides a purification device and a filtration device that can eliminate the danger of carbon monoxide poisoning by further decomposing with carbon ozone and other toxins contained in the exhaust gas generated from the gas water heater, followed by filtration. An object is to provide a gas water heater provided.

A gas water heater provided with a purification device and a filtration device according to the present invention is provided with at least one ozone generator and at least one filtration device in an exhaust path of an exhaust pipe connected to the gas water heater. The ozone generator is electrically connected to an electric power system, and at the same time the gas water heater is ignited, the ozone generator is also activated to generate ozone, and the generated ozone enters an exhaust path in an exhaust pipe, and exhaust gas The carbon monoxide and other chemical toxins contained in the gas are decomposed, and then the exhaust gas passes through a filter device and is filtered after impurities are exhausted. For this reason, it is possible to prevent the gas water heater from harming the human body due to carbon monoxide generated by incomplete combustion.

The secret of the effect that ozone decomposes off-flavors is its electrolysis. Oxygen atoms (O) that are constituent atoms of ozone are negatively charged, oxygen molecules (O2) are positively charged, and ozone is negatively charged. When a binding object with positive electricity is found, ozone oxidizes. This type of action is related to electrolysis that exhibits a large deodorizing effect. The bad smell has a lot of positive electricity, and ozone binds to it (ion bond) and then reacts to become another substance, thereby achieving a deodorizing effect. This kind of action is the same as sterilization and is oxidatively decomposed to achieve a deodorizing effect. In other words, it does not hide the bad odor with the unique smell of ozone, but breaks down the odor source material.

Therefore, the present invention is provided with a device for generating ozone having the above-mentioned disinfection and odor decomposition characteristics on the exhaust path of the gas water heater to decompose carbon monoxide and other toxins contained in the exhaust gas. Thus, the amount of toxins contained in the exhaust gas discharged can be reduced, and the user can be prevented from becoming poisoned with carbon monoxide.

The filtering device of the present invention filters exhaust gas using a honeycomb ceramic filter element of a noble metal catalyst. The ceramic filter element is a ceramic monolith in which different raw materials such as magnesium oxide, aluminum oxide, and silicon oxide are mixed and fired according to a predetermined ratio, and has 100 to 200 holes per square inch. One end of the hole is open and the other end is closed. For this reason, exhaust gas cannot pass directly, it must pass through the passage wall, and the passage wall hole gap is about 7-13u, so it can catch 99% or more toxic particles in the exhaust gas. it can. Furthermore, precious metal paint (mixed in different proportions of platinum, palladium, rhodium, titanium, etc.) is baked on the ceramic surface by secondary processing, so that the precious metal attached to the ceramic surface oxidizes or reduces the toxic gas that passes through it. Can exhaust non-toxic air.

It is the block diagram which showed the Example of the gas water heater provided with the purification apparatus and filtration apparatus of this invention.

As shown in FIG. 1, a gas water heater equipped with a purification device and a filtering device according to a preferred embodiment of the present invention is sequentially provided with at least one ozone generator in an exhaust path of an exhaust pipe 11 connected to the gas water heater 1. 2 and at least one filtration device 3. The exhaust gas generated after the gas is burned by the gas water heater 1 flows directly from the exhaust gas inlet 111 of the exhaust pipe 11, passes through the ozone generator 2 and the filtration device 3 in order, and then exhausts from the exhaust gas outlet 112. Is done. The ozone generator 2 is electrically connected to the electric power system, and when the gas water heater 1 is ignited, the ozone generator 2 is also activated to generate ozone, and the generated ozone immediately enters the exhaust pipe 11 to exhaust gas. Mixed with. Then, the ozone decomposes carbon monoxide and other toxic chemical substances into non-toxic substances or substances with low toxicity, and then the impurities are filtered by the filtering device 3 and discharged into the atmosphere. Is done. The power system electrically connected to the ozone generator 2 is electrically connected to a household AC power source by a power cord.

The filtration device 3 in the embodiment of the present invention is a honeycomb ceramic filter element of a noble metal catalyst. When the exhaust gas whose toxicity has been decomposed by ozone passes through the filtration device 3, contaminants contained in the exhaust gas are filtered and discharged by the honeycomb ceramic filter element of the noble metal catalyst. The ceramic filter element is a ceramic monolith that is baked by mixing different raw materials such as magnesium oxide, aluminum oxide, silicon oxide, etc. according to a predetermined ratio, and has 100 holes per square inch, and one end of each hole. Is open and the other end is blocked. For this reason, the exhaust gas cannot pass directly, it must pass through the passage wall, and the clearance of the passage wall hole is about 7-13u, so it can capture 99% or more toxic particles in the exhaust gas. Can do. Furthermore, precious metal paints (for example, platinum, palladium, rhodium, titanium, etc. mixed at different ratios) are baked on the ceramic surface by secondary processing, so that the precious metals attached to the ceramic surface oxidize the toxic gas that passes through. Alternatively, the air that has been reduced and made non-toxic can be discharged.
