JPS591159Y2 - Pumping amount control device for bubble pump boiler - Google Patents

Description

[Detailed description of the invention] This invention uses the steam bubbles generated in the generator and the warm water inside the generator to form a gas-liquid mixed layer, and uses the so-called bubble pump action to connect the gas-liquid rising pipe to the separator above the generator. A water pumping amount control device in a boiler generator of a natural circulation type hot water heating system that pumps water through a boiler generator and forms a hot water circulation flow path using a water head between the separator, radiator, and generator, in other words, the water pumping amount control device The present invention relates to a circulating water amount control device for adjusting the amount of water, etc.

In the above-mentioned natural circulation type hot water heating system that does not use a circulation pump, the method of adjusting the room temperature by controlling the circulating hot water is to turn the heating source ON/OFF or adjust the heating capacity using a room temperature sensor. You can change the hot water temperature by
One way to do this is to change the circulation flow rate, that is, the amount of pumped water, but in this type of boiler, if you change the combustion capacity of the burner, which is the heating source, in order to change the hot water temperature, the amount of pumped water will also change accordingly. Therefore, the control of heating temperature was very rough.

Therefore, the present invention enables more accurate and detailed control of heating temperature by making it possible to individually control hot water temperature and water pumping amount.

To explain the following with reference to the drawings, reference numeral 1 denotes a generator, and a gas-liquid rising pipe 3 connected to a gas-liquid separator 2 located above the generator mixes hot water in the generator into gas-liquid. The water is pumped to the separator in layers.

A water receiving tank 4 is connected to the generator 1 through a conduit 5 and is also connected to the separator 2 through a pressure equalization pipe 6.

Reference numerals 7 and 8 denote hot water outgoing pipes and return pipes that connect the separator 2 to a radiator and a water receiving tank 4 (not shown).

The generator 1 has a burner 9 disposed below and forms a water jacket (la) around the outer periphery, and a baffle 10 is installed in the combustion gas passage in the generator to replenish the combustion heat of the burner.
is provided.

However, the baffler 10 is supported by a suitable holder 11 so that its installation position can be freely adjusted.

Since the present invention is constructed as described above, by adjusting the position of the baffler 10, for example, by positioning the baffler 10 near the connection part of the gas-liquid riser pipe 3 of the generator 1, the amount of steam bubbles generated in the iron part will increase. In other words, the bubble pump action becomes active and the amount of pumped water can be increased.

Moreover, if the baffler 10 is located away from the gas-liquid riser pipe connection part, contrary to the above, the amount of steam bubbles generated at the iron part will increase, but the bubble pumping action will be performed before reaching the gas-liquid riser pipe connection part. Since the energy is weakened, water cannot be pumped as much as described above.

In other words, the amount of pumped water will decrease relatively.

An increase or decrease in the amount of pumped water changes the amount of liquid stored in the separator and changes the flow rate to the radiator, so the amount of heat radiated by the radiator is controlled.

At this time, if the heating amount of the burner is also adjusted, the hot water temperature and the amount of pumped water can be controlled separately, making it possible to easily and accurately obtain the desired heating temperature.

As described above, the present invention consists of a generator in which a vine burner is placed below to adjust the amount of heating and a jacket is formed around the outer periphery, and an air bubble is provided in the upper part to pump hot water inside the generator. In a natural circulation hot water heating system in which water is pumped to a liquid separator, a hot water circulation path is formed between the separator, a radiator, a water tank, and a generator, a burner is installed in the combustion gas passage in the generator. By installing a baffle that replenishes the combustion heat and adjusting its installation position on the same night, it is possible to increase or decrease the amount of water pumped by the bubble pump, making the structure simpler, easier, and more accurate without using any mechanical control device. A device with excellent practical effects such as being able to control heating temperature can be provided.
