Description

[Detailed explanation of the invention] This invention relates to an improvement in a heating system that uses exhaust heat from combustion in a combustor to generate hot water and circulates this hot water to a radiator installed at the desired location. be.

By the way, the applicant had previously filed Utility Application No. 58-121586.
As shown in Fig. 1, an exhaust heat utilization pipe 3' having a water chamber 6' is connected to the middle of the exhaust pipe 2' extending from the combustor 1', and the hot water heated by the exhaust heat is radiated. We have proposed a heating device that circulates heat to the container 21' via a pump 20'.

However, this conventional heating system had a water inlet 11' for replenishing water at the top of the water chamber 6' and an air vent hole 12' for smooth water injection, so the combustor was used alone. If all the water is drained from the water chamber 6' and the product is heated dry, the characteristic odor of dry heating will be emitted into the guide from the inlet 11' and air vent hole 12', and the disadvantage is that it may be caused by long-term use. This has the drawback that foul odors are emitted into the room due to the evaporation of dirty or putrid water or hot water, and also the evaporation of antifreeze solution injected with water to prevent freezing.

This invention focuses on this point and aims to exhaust the bad odor from the inside of the exhaust stack to the outdoors by using the draft generated by combustion in the combustor. In the case where an exhaust heat utilization tube 3 having a water chamber 6 in the middle is connected, a substantially hat-shaped odor guide tube 13 is attached to the upper end of the exhaust heat utilization tube 3, and a body 15 of the odor guide tube 13 is attached. has a larger diameter than the inner shell 4 of the exhaust heat utilization cylinder 3, and a flow path 16 is formed between the two, and the exhaust pipe 2 is connected to the upper part of the odor guide pipe 13, so that the bad odor in the water chamber is removed from the inside of the exhaust pipe. It has the characteristic that it is prevented from being sucked in and emitted outdoors and emitting bad odors indoors.

Next, an embodiment of this invention will be described.The basic structure is almost the same as the conventional example, and 1 is a combustor that uses oil or gas as fuel, and is equipped with a combustion burner (not shown) etc. inside. The exhaust pipe 2 is extended from the exhaust port.

Reference numeral 3 denotes an exhaust heat utilization cylinder which is connected to the middle of the exhaust pipe 2 and generates hot water by exchanging heat between exhaust gas and water. The outer shell 5, which has a larger diameter than the inner shell 4, forms a water chamber 6 for storing water therein, and a coil-shaped heat exchanger 7 is installed inside the inner shell 4, and the heat exchanger is inserted into the inner shell 4. Mizuguchi 8
is connected to the water chamber 6 so as to communicate with the water outlet 9.
penetrates the water chamber 6 and protrudes from the outer body 5, and a partition plate 10 at the top of the water chamber 6 has a water inlet 1 for injecting water.
1 and an air vent hole 12 for smooth water injection.

Reference numeral 13 denotes a headless odor guide cylinder with an open head and a substantially hat-like shape, and the lower part has an outer peripheral edge extending from a flat surface that rises upward and then bends downward to form a fitting part 14. The outer diameter of the body 15, which stands upright from the flat surface, is smaller than the outer diameter of the inner shell 4 of the exhaust heat utilization cylinder 3. The upper part of the body 15 has a smaller diameter than the inner body 4 and forms a connecting part 17 into which the exhaust pipe 2 fits, and a water inlet 18 is provided on the flat surface. It is open and a dust intrusion prevention net 19 is attached to the back side.

Reference numeral 19 indicates a return pipe opening, 20 indicates a pump that circulates hot water between the water chamber 6 and a radiator 21 such as a floor heating device, and 22 and 23 indicate circulation pipes.

Next, the operation will be described. The combustor 1 starts combustion by a well-known combustion operation, and the water previously stored in the water chamber 6 is heated by exhaust gas to a predetermined temperature.

If the pump 20 is started at the same time, the hot water in the water chamber 6 is circulated to the radiator 21 to perform heating.

When this hot water rises in temperature, a portion of it evaporates and tries to be discharged from the water chamber 6 into the room through the water inlet 11 and the air vent hole 12. However, a draft is generated inside the inner shell 4 due to combustion. Therefore, steam is sucked from the flow path 16 and discharged from the exhaust pipe 2 to the outdoors.

As a result, dirty or putrid water, as well as vapors such as antifreeze that cause odor, are discharged outdoors, so no odor is emitted indoors.

Of course, even when the combustor is used alone and the water chamber is empty, no foul odor will be emitted into the room in the same way as described above.

As described above, this invention is based on an exhaust heat utilization pipe 3 which has a water chamber 6 in the middle of the exhaust pipe 2 extending from the combustion chamber 1.
In this case, a substantially hat-shaped odor guide tube 13 is attached to the upper end of the exhaust heat utilization tube 3, and the body 15 of the odor guide tube 13 has a diameter larger than the inner body 4 of the exhaust heat utilization tube 3. Since a flow path 16 is formed between the two and an exhaust pipe 2 is connected to the upper part of the odor guide pipe 13, bad odors caused by any cause are discharged outdoors and the interior can be kept clean. .
