Its advantages are less investment and high safety and reliability.

Description

Skyscraper is adopted dim partitioning device

The invention belongs to a kind of heating equipment.

The skyscraper heating system is because pressure of equipment abilities such as thermal source pressure limit and radiator can not be too high, and there are two kinds of forms in the system of present common application.A kind of is the isolation type system, promptly adopts heat-exchange apparatus to carry out the secondary exchange of heat, this mode equipment investment operating cost height, and heat loss is big in the heat transfer process; Another kind of mode is direct-connected double-water-tank system, but because water tank is an open type, and systemic circulation water directly contacts with air, easily makes air enter system, causes the system equipment corrosion.

The purpose of this utility model provides a kind of simple in structure, and equipment investment is few, the operational efficiency height, and backwater decompression when directly heating agent being pressurizeed makes high district be the heating districting device for high-rise buildings of closed circulation system.

The technical measures of the invention are as follows: heating districting device for high-rise buildings is made up of supply channel and water return pipeline, it is characterized in that: (A → B) inlet is installed thermometer (13) to supply channel successively, Pressure gauge (6), electronic isolating valve, (3), stop valve (8), pressurized circulation water pump (1), stop valve (8), check-valves (7) Pressure gauge (6), (C → D) is setting pressure table (6) successively for water return pipeline, stop valve (8), pressure-reducing valve (2), stop valve (8), electronic isolating valve, (3), Pressure gauge (6), thermometer (13), pressure pump electric cabinet (5) is contained in the pressure sensor (4) on the return pipe with pressurized circulation pump (1) respectively and two electronic isolating valve,s (3) of being contained on the water supply return pipe are connected, extra feed tank (12), stop valve (8), make-up pump (9), stop valve (8) and check-valves (7) constitute water pipe and link on the water return pipeline, make-up pump electric cabinet (11) is connected with pressure sensor (10) and make-up pump (9) respectively, has promptly constituted heating districting device for high-rise buildings.

Description of drawings:

Fig. 1 is the heating districting device for high-rise buildings schematic diagram;

1-pressurized circulation water pump wherein, 2-pressure-reducing valve, the electronic isolating valve, of 3-, 4-pressure sensor, 5-pressure pump electric cabinet, the 6-Pressure gauge, 7-check-valves, 8-stop valve, 9-make-up pump, the 10-pressure sensor, 11-make-up pump electric cabinet, 12-extra feed tank, 13-thermometer.

Fig. 2 is a skyscraper heating system schematic diagram;

Wherein (E → F) is low district heating system, and (A → D) is the high rise zone heating system, and G (ABCD) is a heating districting device for high-rise buildings in the II district in the I district.

This device running is as follows:

At first by electric cabinet 5 controls electronic isolating valve, 3 is opened, started simultaneously pressurized circulation water pump 1, will hang down recirculated water A point hydraulic pressure P in district's heat supply network_AThe required pressure P of the required recirculated water B point of the paramount district heating system of pressurizeing_B High district's heating backwater is during to the C point, by pressure-reducing valve 2 with C point pressure P_CNear D point hydraulic pressure P_D, pressurization and pressure relief value are high district heating system hydrostatic pressure reduction H. So just Realized the confession of high district, pressure of return water P_AAnd P_DWith low district's confession, pressure of return water P_EAnd P_FIdentical. That is to say that this device of application can reach high district heating system and form in parallel with the low pressure heating system Form. If during operation, pressure-reducing valve breaks down, when not having depressurization, for guaranteeing not Connected with low sound zone system in high district, cause low district device damage, this device is provided with pressure sensor, When above-mentioned situation occurring, when pressure sensor surpasses setting pressure, signal is reached electric cabinet 5, Close then circulation force (forcing) pump 1 and electronic isolating valve, 3, thus make high district with low separate disconnected. Subtract Pressure valve adopts mechanical spring formula pressure loading valve, but decompression pressure reduction manual adjustment is set. When adopting be Unite when out of service, out of service by electric cabinet control pressurized circulation pump 1, electronic partition simultaneously Valve 3 cuts out. Make high sound zone system B point to the C point and hang down the sound zone system partition, form independent closed system. For keeping the independent closed system in high district, hydrostatic pressure does not descend, and this device is established pressure sensor, Dang Gao district hydrostatic pressing drops under the setup pressure value prescribes a time limit, and adopts frequency conversion automatically to control by electric cabinet Make-up pump is high sound zone system moisturizing, and pressurization sets on the force value when pressure sensor reaches In limited time, make-up pump 9 cuts out automatically. Extra feed tank 12 is independent open tank. Pressure gauge 6, Thermometer 13 is artificial measuring instrument, and stop valve 8 is the usefulness of artificial cutting out pipeline.

According to above explanation, referring to accompanying drawing, introduce an embodiment of certain heating districting device for high-rise buildings, its main equipment selection is as follows:

Pressurized circulation pump (1) IRG65-160 (I) AQ=44m ³/ hH=28mH ₂ON=5.5KW; Pressure-reducing valve (2) Y410 type DN100; Electronic isolating valve, (3) ZDF series multifunctional magnetic valve DZ100; Pressure sensor (4) PMC133 type; Pressure pump electrical control cubicles (5) PCM1 type; Pressure gauge (6) Y40 type D _N≤ 1.6MP _aCheck-valves (7) H41T-16 DN100; Stop valve (8) J41T-16 DN100; Make-up pump (9) 32LG-15 * 4 Q=6m ³/ h H=60mH ₂O N=2.2KW; Pressure sensor (10) PMC133 type; Make-up pump electric cabinet (11) PCM2 type; Water supply tank (12) 2m ³Length * wide * height=1200 * 1800 * 1200 (mm) are selected from national water supply-drainage discipline standard collective drawings S151 (); Thermometer (13) glass liquid thermometer.

The good effect of heating districting device for high-rise buildings is, is example with certain high level (14) layer building, and area is 22000 square metres, total height is 48 meters, and heating system one to eight floor is low district, and nine to 14 floor are high district, high district construction area is 9500 square metres, thermic load be 731500 kilocalories/hour.This building and heating heating agent is 95～70 ℃ a hot water.(1) disposable apparatus is thrown few.Compare with the isolation type system and to have saved plate type heat exchanger, dirt separator has only increased pressure-reducing valve, and only equipment investment is saved 180,000 yuan, because of having cancelled heat exchanger, keeps high district heating medium parameter still to be 95～70 ℃, and fin reduces 20%, can reduce investment outlay 5～60,000 yuan again.(2) energy savings.Because cancelled the heat exchange link, also just stopped meaningless heat energy loss.(3) the automaticity height is safe and reliable to operation, convenient management.(4) heating equipment is few, and floor space is little, has saved investment for the user again.Adopt this skyscraper partitioning device, can receive extraordinary social benefit and economic benefit, China's heating is vast in territory, and skyscraper is ten hundreds of, and promoting for this device provides vast market.
