Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention The present invention relates to a hot water boiler that can supply hot water at a predetermined temperature by burning organic fuel.

Conventional technology and problems In conventional hot water boilers, firewood, coal, etc. are input through the fuel input port and burned, ash is taken out from the outlet at the bottom, and water is heated with the combustion heat of the fuel. Sometimes, a large amount of ignition occurs suddenly, so the necessary amount of air cannot flow in, resulting in black smoke. Also, when fuel with a high moisture content is injected, a large amount of smoke and water vapor are generated.
Since the temperature does not rise, there is a drawback that efficiency decreases.

Therefore, the amount of shrines that could be used as fuel was limited.

Moreover, when the amount of hot water used is large, there is a drawback that the water temperature decreases.

Purpose of the Invention The present invention provides a method for treating organic wastes such as wooden sheds, chip parks, etc.
Uses firewood, garbage, rubber, tires, waste cardboard, etc. as fuel,
The purpose is to enable complete combustion, control combustion according to water temperature, and supply hot water at a predetermined temperature. Examples will be described in detail below.

Embodiment of the Invention FIG. 1 is a schematic sectional view of an embodiment of the invention, and FIG. 2 is a top view. ■ is a lid, 2 is a fuel injection tube, and the lid 1 has a hinge structure on one side at the top of the fuel injection tube 2 for opening and closing.
il, and is configured to be completely airtight when closed. The fuel injection cylinder 2 is composed of an outer cylinder 2a and an inner cylinder 2b made of stainless steel or the like, and a plurality of slits 2C are formed in the lower part of the inner cylinder 2b. This slit 2c is intended to increase the convection effect of the gas generated from the fuel and to prevent the fuel from expanding outward due to the heat generated by the fuel and falling downward, thereby preventing the formation of a fuel shelf. Further, 3 is a hot water tank, and it is preferable to provide a heat-insulating exterior plate (not shown) on the outside.

Above this hot water tank 3 (ILS has a water inlet 17 and a hot water inlet 18)
is established. The pipe communicating with the water supply port 17 is extended to -1: (1%) of the hot water tank 3, and the hot water supply port 1B is configured to supply hot water from two parts of the hot water 4 (13).

A combustion chamber 5 and a dust chamber 7 are formed by the partition plate 4 and the gas guide plate 6, and an exhaust pipe 8 is provided in the dust chamber 7, and the gas burned in the combustion chamber 5 passes through the dust chamber 7 along the path indicated by the arrow. As a result of the reduction in the flow velocity and flow path conversion of the exhaust gas that passes through the exhaust pipe 8 and enters the dust chamber 7, the dust in the exhaust gas is deposited in the dust chamber 7.

The ignition port 9 and the discharge port 10 are always sealed with airtight lids, and after putting fuel into the fuel injection cylinder 2, the lid of the ignition port 9 is opened to light the fuel, and after igniting, the fuel is sealed with the lid. . Further, the ash remaining after the fuel is burned can be taken out from the ignition port 9. Further, the dust accumulated in the dust chamber 7 is discharged from the discharge port 10.

The blow pipe 11 has a large number of holes formed therein and blows out air from the blower 15 through the holes. A gap is formed between the tip of the blow pipe 11 and the outer cylinder 2a through which gas generated from the fuel can flow out into the combustion chamber 5. ing. A plate I3 is provided on top of the injection pipe 11 to prevent the holes in the injection pipe 11 from being blocked by fuel, thereby making it possible to form a large bag. Also, the blow pipe 12 that supplies air from the blower 15 to the combustion chamber 5 is the blow pipe 11.
is located at the bottom of the. Further, a balanced damper 14 is provided to prevent air from naturally flowing in from the blower 15 side when the blower 15 is stopped. Also blower I5
is driven by a motor 16, and the motor I6 is driven according to the operation of thermostats 1-19 installed in the hot water tank 3. For example, water is supplied from the water supply port 17 and the water inside the hot water tank 3 is heated. When the temperature drops, the thermostat 19
When the temperature reaches 1 V, the motor 16 is driven, and when the temperature reaches a predetermined temperature or higher, the motor 16 is stopped. Such control can be performed by known means.

FIG. 3 is a perspective view of the main parts of the blow pipe 11 and the blow pipe 12. The blow pipe 11 has a plurality of holes formed therein, and a plate 13 is provided with
A gap is formed between the tip of the blowing pipe 11 and the outer cylinder 2a, as shown by the arrow, through which gas generated from the fuel can flow out.

The blow pipe 12 is for directly supplying air to the baking chamber 5.

The lid 1 is opened, organic fuel is poured into the fuel injection cylinder 2, and the lid 1 is closed to create a hermetically sealed state. Next, a flammable piece of paper or the like is ignited from the ignition port 9, and the ignition port 9 is sealed. In this case, it is preferable to install a catalyst number in the blowing pipe 11. When the blower 15 is not driven, only a very small amount of leaked air from the ignition port 9 etc. is supplied to the fuel injection tube 2, so the combustion state is such that a flame is generated and the timing is not stable. , the fire becomes buried. The heat of the buried fire causes the fuel to dry, generate gas, and carbonize. This force fills the fuel injection cylinder 2, and the water in the hot water tank 3 around the fuel injection cylinder 2 has a G temperature of, for example, about 60 to 80°C.

The water supply port 17 is directly connected to the water supply, and the valve is opened and closed according to the water level in the hot water tank 3, and the hot water supply port 18? When hot water starts to be supplied through the connected piping, low temperature water is supplied into the hot water tank 3, so the water temperature drops, and the thermostat 19 detects the drop in water temperature and applies voltage to the motor 16 from the power supply.

As a result, air from the blower 15 is supplied by opening the damper 14, and is ejected from the hole of the blow pipe 11 into the fuel injection cylinder 2.

It is also supplied to the combustion chamber 5 from the blast pipe 12 . Fuel injection canister 2
The buried fuel starts to burn due to the air supplied into the combustion chamber 5, generating a large amount of heat, and gas flows into the combustion chamber 5. Since air is supplied to the combustion chamber 5 through the blast pipe 12, the gas is completely combusted and a large amount of heat is generated.

The burned gas rises in the combustion chamber 5, flows into the dust chamber 7 from the upper part of the gas guide plate 6, descends toward the lower part of the dust chamber 7, and flows into the exhaust pipe 8 from the lower part of the gas chamber 7. and is discharged to the outside.

Combustion in the fuel injection cylinder 2 and &, l in the combustion chamber 5
Due to the heat generated by the combustion, the temperature of the water in the hot water tank 3 rises rapidly. Further, when the temperature inside the hot water tank 3 reaches a predetermined temperature or higher, the thermostat 19 detects the temperature and stops driving the motor 16. As a result, the supply of air into the fuel injection tube 2 and the combustion chamber 5 is stopped, and the fuel near the blowing pipe 11 becomes buried, which reduces heat generation and prevents the temperature rise in the hot water tank 3. It will be suppressed. Therefore, even if hot water supply is started, hot water at a predetermined temperature can be supplied.

By carbonizing and dry distilling the fuel charged into the fuel injection tube 2 and generating gas, complete combustion of the fuel becomes possible when forced air is blown by the blower 15.
Any organic material can be used as the fuel. In addition, the fuel may form a shelf due to sintering within the inner cylinder 2b, but the formation of the slit 2C makes it easier for the lower part of the cylinder 2b to expand, and before the fuel shelf is formed. Since the fuel falls on the ground, it is possible to prevent the occurrence of fuel shelves. Further, convection of generated gas occurs between the inner cylinder 2b and the outer cylinder 12a through the slit 2C, and it is possible to generate gas from the fuel and maintain the water temperature while maintaining the buried state. The slope 13 prevents the fuel from getting cold in the hole of the blowing pipe 11 and forms a fire bag around the blowing pipe 11. When the blower 15 is driven, the air ejected from the hole of the blowing pipe 12 As the pressure inside the fuel injection tube 2 increases, the gas filling the fuel injection tube 2 flows out from the gap between the tip of the blowing pipe 12 and the outer tube 2a, causing a buried fire or Since there is a layer of fire in a convulsive state, it is blown out in an ignited state, and the combustion chamber 5
It is completely burned out by the air from the blower pipe 12 inside.

Also, during a power outage, the blower 15 cannot be driven.
In that case, by opening the ignition port 9, air will naturally flow in, making it possible to burn fuel and gas and obtain a calorific value of about 60% culm, even if the calorific value is less than when the blower 15 is operated. be able to.

Further, in the above-mentioned embodiment, the fuel injection tube 2 and the hot water tank 3 have a cylindrical shape, but it goes without saying that they can have any shape such as a rectangular tube shape. The thermostat I9 can also be replaced by another temperature detector, and any configuration can be adopted as long as it has a detection capability that can maintain the water temperature in the hot water tank 3 within a predetermined range. I can do everything. In addition, various changes may be made without being limited to the above-mentioned embodiments.

It is possible.

Achievements of the Invention As explained above, in the present invention, since fuel can be selected arbitrarily, waste can be used, and fuel costs can be significantly reduced. Furthermore, even if a large amount of hot water is used, the amount of heat generated is increased due to the direct combustion of the fuel and the combustion of gas generated by carbonization and dry distillation.
A predetermined temperature can be maintained. Furthermore, since the sleeve I- is formed in the inner cylinder 2b, it is possible to promote gas convection and prevent the formation of fuel shelves. Further, the plate 13 on the blowing pipe 11 can form a large fuel bag, which can promote complete combustion of the fuel. In addition, the amount of heat generated is increased by forced air blowing by the blower 15, and when the water temperature in the hot water tank 3 rises, simply by stopping the blower 15, it is possible to shift to a buried fire state and reduce the amount of heat generated. It has the advantage of being able to automatically adjust the water temperature, making it possible to always supply hot water at an appropriate temperature.
