Abstract

PURPOSE:To obtain the space heating device of an electric sauce unnecessity by a method wherein a control tank consisting of a liquid chamber and a steam chamber is provided on the upper side of a trap tank and a valve communicating the liquid chamber and the steam chamber by a level detecting means is provided in the device. CONSTITUTION:A generator 2 is provided on the way of an exhaust path. Working liquid 8 of the latent medium becomes a high temperature and high pressure by exhaust gas, the pressure of the trap tank 4 rises and the high temperature working liquid 8 is discharged to a heat exchanger for radiation 3. The low temperature working medium 8 due to radiation enters in the liquid chamber 7. A float 6 rises by rising of the level whereby the valve 5 is pushed up and the liquid chamber 7 is communicated to the steam chamber 9, thereafter, the steam of the working liquid 8 enters into the steam chamber 9 while the pressure of the trap tank 4 almost equals to the pressure of the liquid chamber 7. Accordingly, the working liquid 8 of the liquid chamber 7 drops by tare weight to the trap tank 4 through a check valve 14. When the level of the working liquid 8 falls at the liquid chamber 7, the valve is closed and the low temperature working liquid 8 flows into the liquid chamber 7. Heat of a exhaust chimney 1 is transferred to the heat exchanger for radiation 3 due to the flowing of the working liquid 8 and the floor heating or the like may be effected in the room.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a heating device that safely utilizes exhaust heat from exhaust gas from a combustor for floor heating or the like without power.

2. Description of the Related Art As shown in FIG. 2, a conventional heating device of this type includes a generator 2 installed inside an exhaust vent 1, a heat radiation heat exchanger 3, and an expansion pump 4 connected in series. The working fluid 6 was circulated, and the heat in the generator 2 was transferred to the heat exchanger 3 for heat radiation, and the exhaust heat was used for heating.

Problems to be Solved by the Invention However, with the above configuration, the pump 5 stops in the event of a power outage, but if the combustion in the combustor does not stop, the working fluid 6 in the expansion tank 4 may boil, or if an earthquake occurs. In this case, high-temperature water may dissipate due to a fall, the hydraulic fluid 6 may evaporate during long-term use, resulting in dry firing, the vibration noise of the pump 5 may become harsh as it is used indoors, or the power supply may be disconnected. It had a number of problems, such as being unable to be used in places without.

The present invention 811 solves the problems of the conventional technology, and aims to provide a heating device that is safe and noiseless and can utilize waste heat without using a power source.

Means for Solving the Problems In order to solve the above problems, the heating device of the present invention includes a generator installed internally or externally in the exhaust vent, a liquid storage tank above the generator, and a liquid storage tank. A control tank is provided above the storage tank, and a heat exchanger for heat radiation is provided below the generator.The inside of the control tank consists of a lower liquid chamber and an upper vapor chamber. A valve is provided for communicating the liquid chamber and the steam chamber by means of means. In addition, the piping that connects each element equipment includes an outgoing pipe that connects the generator and the heat exchanger for heat radiation, a return pipe that connects the heat exchanger for heat radiation and the liquid chamber of the control tank, and a pipe that connects the liquid chamber of the control tank and the liquid reservoir. It consists of a rib that connects the tank via a check valve, and a communication pipe that connects the liquid storage tank and the control tank vapor chamber.

Effect of the present invention With the above-described configuration, the working fluid of the latent heat medium heated by the generator evaporates and the pressure increases, but since the valve in the control tank is open, it is not pushed out to the heat exchanger for heat radiation. After dissipating heat, it becomes low temperature and flows into the liquid chamber at the bottom of the control tank through the return pipe.

When a liquid level detection means detects that a certain amount of working fluid has been stored in the liquid chamber and the valve is opened, high-pressure steam in the liquid storage tank is introduced from the steam chamber into the liquid chamber, so it is activated by its own weight. The liquid flows from the liquid chamber into the liquid storage tank.

As described above, the heat of the generator can be transferred downward without requiring any power source.

EXAMPLE An example of the present invention will be described below with reference to the accompanying drawings. In FIG. 1, reference numeral 1 denotes an exhaust outlet of a combustor, and a generator 2 is disposed inside the exhaust passage, and a heat exchanger 3 for heat radiation such as floor heating is provided below the generator. A liquid storage tank 4 is provided at the upper outlet of the generator, and further above there is a liquid chamber 7 in which a float 6, which is a liquid level detection means for opening and closing a valve 5, is installed, and a steam chamber in which the vapor of the working liquid 8 is stored. A control tank 10 consisting of nine capacitors is provided. The generator 2 and the heat exchanger 3 for heat dissipation are connected by an outgoing pipe, and the heat exchanger 3 for heat dissipation and the liquid chamber 7 of the control tank 10 are connected by a return pipe 13 via the first check valve 12. ing. In addition, the liquid chamber 7 and the liquid storage tank 4
The upper part of the liquid storage tank 4 and the steam chamber 9 of the control tank 4 are connected by a communication pipe 16.

In the above configuration, the exhaust gas from the combustor heats the generator 2 in its flow path, so the internal latent heat medium working fluid 8 becomes high temperature and high pressure, and the pressure inside the liquid storage tank 4 also rises, causing high temperature operation. The liquid 8 is pushed out to the heat exchanger 3 for heat radiation. Working fluid 8 that has become low temperature due to heat dissipation in heat exchanger 3 for heat dissipation
is introduced into the liquid chamber 7 through the return pipe 13. When the liquid level of the working liquid 8 in the liquid chamber 7 rises, the float 6 also rises, pushing up the valve 5 and communicating the liquid chamber 7 and the steam chamber 9. Therefore, the vapor of the working liquid 8 in the liquid storage tank 4 communicates with each other. It is introduced into the steam chamber 9 of the control tank 10 through the pipe 16, and the liquid/sump tank 4
(!-The pressure in the liquid chamber 7 becomes approximately the same value.

Therefore, the hydraulic fluid 8t/i in the fluid chamber 8 is dropped into the fluid storage tank 4 through the counter rib 15 and the second check valve 14 due to its own weight. When the level of the hydraulic fluid 8 in the fluid chamber 7 decreases, the float 6 also decreases, the valve 5 becomes closed, and the low-temperature hydraulic fluid 8 flows into the fluid chamber 7 through the return pipe 13 again. As described above, due to the flow of the working fluid 8, the heat in the exhaust vent 1 is carried into the heat radiating heat exchanger a, so that floor heating or the like can be performed.

Effects of the Invention As described above, the heating device of the present invention provides the following effects.

(1) The circulation of the hydraulic fluid is a completely sealed, non-powered system that utilizes steam pressure, so unlike electric pump systems, the hydraulic fluid may cause bumping during a power outage, or high-temperature fluid may fall over during an earthquake. It is safe as an indoor heating device because it does not scatter indoors.

(2) Since it is a completely sealed system, there is no need for evaporation of the working fluid, dry firing, and rinsing like in the past, and no need for fluid replenishment, so there is no need for maintenance.

(3) A device with a built-in pump as an indoor heating device K
However, since it does not have high-speed rotating parts, no noise is generated, making it a comfortable indoor heating device.

(4) If the combustion device does not require a power source, exhaust heat recovery can be performed for floor heating, etc. even in places without a power source, dramatically expanding the degree of freedom in installation.

(5) In the conventional system, scale was generated inside the generator, significantly impairing the heat exchange performance, but since the present invention is a closed system, reliability can be ensured throughout the long stem.
