Description
Technical field
The present invention relates to a kind of heating system loop and improve, particularly one makes the skyscraper high low area adopt same heating water system.Skyscraper direct connection heating self-pressurization unit.Promptly high district heating system part high pressure backwater supplies water through the low district's heating of water ejector injection outer net, supplies water to skyscraper direct connection heating unit suction pipeline section.
Background technology
Skyscraper is on the increase.Realize directly being connected heating round skyscraper heating system and urban heating network and developed many skyscraper direct connection heating units.First kind is low the district by municipal heating network heat supply, and high district establishes cutout by the force (forcing) pump pressurization on the total return pipe of building top layer, and rotary stop apparatus is installed in the return pipe lower end, by overflow elimination pressure of return water, makes the high low area of skyscraper realize directly being incorporated into the power networks; Second kind is to reduce pressure of return water by pressure-reducing valve, adopts compressed air to control the unit that quick isolating valve, makes system's open and close; The third is to reduce pressure of return water by pressure-reducing valve, adopts the skyscraper heating districting equipment of solenoid control backwater open and close; The 4th kind is to adopt block device to reduce pressure of return water and control backwater open and close equipment.But all there is a common defects in they, and all by having consumed of inactions such as cutout, pressure-reducing valve, block device, the high pressure of return water of distinguishing does not make full use of high district backwater potential energy, does not meet energy-conservation requirement.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of backwater potential energy that utilizes, and solves the unit of higher temperature water outer net to lower temperature water heating system or geothermal heating system direct heating.Kao Gao district heating part high pressure backwater supplies water through the low foreign network of water ejector injection, supply water to skyscraper direct connection heating unit suction hose, improve the dynamic head that skyscraper direct connection heating unit suction hose supplies water, reduce skyscraper direct connection heating unit water pump power consumption, but saves energy 50～70%, prepare the required hot water of heating operating mode simultaneously, satisfy the heating requirement.Owing to establish check-valves at low district's water supply pipeline section, pressure can not be delivered to low district heating system, makes the heating system safe operation.
In order to solve the problems of the technologies described above, the present invention has adopted following technical scheme: this skyscraper direct connection heating self-pressurization unit, form by water ejector, check-valves and piping; Water inlet segment is arranged before the check-valves, can link to each other with the feed pipe of municipal heating network, the water outlet pipeline section behind the check-valves can link to each other with the suction hose of skyscraper direct connection heating unit by water ejector; The water ejector water inlet segment is connected with the height district total return pipe of heating system high pressure of adjustable throttle amount, and the water outlet pipeline section can be connected with skyscraper direct connection heating unit suction hose.Be respectively equipped with block valve on the water inlet segment of water ejector and the water outlet pipeline section; Check-valves water outlet pipeline section and water ejector water outlet pipeline section are provided with the bypass pipe block valve, and the tube connector of check-valves water outlet pipeline section and water ejector is provided with block valve.The water ejector water inlet segment is provided with the pressure increase and opens auto hydraulic backwater control valve, and water outlet pipeline section relief tube is provided with pressure and increases the hydraulic control valve of closing.Water pump water outlet pipeline section pressure increases when skyscraper direct connection heating startup of unit, and hydraulic pressure control valve pressure increases opens waterpower backwater control valve, and hydraulic pressure control valve pressure increases the hydraulic control valve of closing simultaneously on the relief tube.Skyscraper direct connection heating unit suction pressure is improved and the mixed heating hot water that meets working condition requirement of making.Make full use of high district heating system backwater potential energy, play the effect of supplying water and pressurizeing, realize that potential energy is transformed into kinetic energy to the heating of height district.
Height district heating part high pressure backwater with potential energy supplies water through the low district's heating of water ejector injection, and the dynamic head that the suction pipeline section of raising skyscraper direct connection heating unit supplies water reduces skyscraper direct connection heating unit power consumption.Realize mixing water and regulate temperature.In order to move conveniently, on water ejector inlet tube and outlet tube and check-valves outlet pipe, be equipped with block valve, between the water ejector inlet tube and outlet tube, be provided with bypass pipe and block valve, when skyscraper direct connection heating self-pressurized system breaks down, can close the block valve of block valve on the water ejector inlet tube and outlet tube and check-valves outlet pipe water inlet injector pipeline section, open the block valve on the bypass pipe, make the circulation of heating system water, skyscraper direct connection heating unit is normally operation still.
The present invention compared with prior art has following advantage, and saves energy is safe and reliable, keeps in repair easyly, and cost is low, is convenient to popularize, for skyscraper and the big building area of the physical features discrepancy in elevation adopt city high-temperature water outer net direct heating to bring great convenience.
