Description

Energy-conservation supercharging heating plant

Affiliated technical field

The utility model belongs to carbonated drink exchange heat supply process, mainly proposes a kind of energy-conservation supercharging heating plant.

Background technology

The heat supply with vapour, water heat exchanger (heating, hot water) device in using now, its structural design is very unreasonable, as does not have the recirculated water actuating mechanism, and when steam pressure did not reach predetermined value, water can't circulate in the whole device; Do not design check-valves, water easily flows backwards, and produces easily that water hangs down and pipe vibration, does not design relief valve, in case hydraulic pressure too highly has only the draining of shutdown, lack the moisturizing function during for heating, the pipeline lack of water has only shutdown.Because whole device unreasonable allocation causes fluctuation of service, whole in addition device can not be realized control automatically and regulate in the existing heating plant.

Summary of the invention

The purpose of this utility model promptly is to propose a kind of energy-conservation supercharging heating plant, makes its structural design more be tending towards reasonable and practical, thereby the assurance device reliability service remedies the existing existing deficiency of heating plant.

The utility model is finished the technical scheme that its invention task takes: heating plant mainly comprises Cold water supply pipeline, steam suppling tube road, steam-water heat exchanger and water return pipeline; Parallel connection starts water pump on the pipeline of heat exchanger water side, and in the water side that starts water pump check-valves is set; Start water pump and flow, assist heat exchanger to start in order to injection water; Return water temperature is too high, steam pressure is crossed and made water normal circulation in the device when hanging down, and is the device water filling.Setting is by the check-valves of the stop valve water side of water pump and water pump water inlet end, the water compensation mechanism that stop valve is formed, and it is attempted by on the inlet pipeline of heat exchanger and with the water source and is communicated with; Think timely moisturizing when the device lack of water.On water return pipeline and put safety relief valve, so that whole device normally moves.Enter at steam stop valve and check-valves are set on the pipeline, finish this device work and circulation, and anti-sealing adverse current.

The PLC programmable controller is set in the device, to be arranged on the stop valve that stop valve, steam on the water return pipeline enters on the pipeline simultaneously and adopt motor-driven valve, the Pressure gauge that Pressure gauge, the steam that is arranged on the water return pipeline is entered on the pipeline adopts electric node manometer, the thermometer that thermometer, the steam that is arranged on the water return pipeline is entered on the pipeline adopts the electrical nodes thermometer, stop valve on the Cold water supply pipeline is adopted electromagnetic valve structure, switch board control by mainly being made of the PLC programmable controller constitutes intelligent automatic heating plant.

The energy-conservation supercharging heating plant that the utility model proposes, its overall structure is comparatively scientific and reasonable, and whole device reliability of operation is further improved, and can effectively overcome the existing existing above-mentioned defective of heating plant.

The specific embodiment

The accompanying drawing that provides is in conjunction with the embodiments further specified its structure:

As shown in Figure 1, it mainly comprises Cold water supply pipeline, steam suppling tube road, steam-water heat exchanger and water return pipeline; Stop valve 2 and check-valves 20 are set on the Cold water supply pipeline,, pollution discharging filter 21, thermometer 5, Pressure gauge 11, stop valve 1 and check-valves 20 are set on the water return pipeline in case the water adverse current in the locking apparatus is gone into the Cold water supply pipeline; The effect of thermometer 5 is to detect return water temperature, when temperature is high, makes to start water circulating pump 10 startups, and the stop valve 8 that turns off steam simultaneously and enter pipeline does not allow steam enter.When return water temperature hangs down, reopen stop valve 8, steam is entered, start water pump 10 and start.The effect of Pressure gauge 11 is to detect pressure of return water, when pressure of return water is high, makes safety relief valve 12 pressure releases.When pressure of return water hangs down, make the water compensation mechanism moisturizing.Steam enters Pressure gauge 15 is set on the pipeline, detects steam pressure, and pressure-reducing valve 22 is set, and steam pressure is regulated, and stop valve 8 is set, so that close when pressure of return water is high, stops steam to enter, and is convenient to the maintenance use.Check-valves 20 is set, enters vapour system to prevent water.The thermometer 24 that detects vapor (steam) temperature is set, (does not comprise pressure) when steam reaches predetermined temperature, heat exchanger 26 is not worked, and starts water pump 10, finishes the circulation of water in device.Water inlet end at heat exchanger 26 is provided with Pressure gauge 23, in order to detect the heat exchanger intake pressure.In the water side of heat exchanger 26 thermometer 16 is set,, and stop valve 7 and check-valves 20 is set, prevent that hot water from passing back into heat exchanger 26 in order to the detection hot water temperature.Parallel connection starts water pump 10 on heat exchanger 26 outlet pipelines, and at the water inlet end that starts water pump 10 stop valve 3 is set, and the water side is provided with stop valve 4 and check-valves 20.On heat exchanger 26 outlet pipelines, Pressure gauge 6 is set, detects water pressure,, make the heat outputting water pressure obtain adjusting by adjusting heat exchanger 26.The energy-conservation pressurization heat exchanger of the utility model patent ZL01239678.8 that heat exchanger 26 can adopt the applicant formerly to propose constitutes energy-conservation supercharging heating plant.The water compensation mechanism that is provided with is made of stop valve 18, the check-valves 20 of water side, the stop valve 19 of water pump 17 and water pump water inlet end, and water compensation mechanism is attempted by on the inlet pipeline of heat exchanger 26.

The utility model work, start-up course:

open stop valve

1,2,3,4,7, starting water pump 10 opens to the device water filling, observe Pressure gauge 5,6, fill with to setting water, valve-off 2 is opened valve 8, steam enters heat exchanger 26, observe Pressure gauge 23, close startup water pump 10 in setting, device is operation normally.

Running: when heat exchanger 26 leaving water temperature table 16 displays temperatures are too high or too low, adjustable valve door 8 apertures.Pressure gauge 5 shows hypertonia or crosses when hanging down safety relief valve 12 pressure releases or water compensation mechanism moisturizing.The holding device pressure stability.Thermometer 11 displays temperatures are crossed when low, open valve 8, close and start water pump 10, can save electricity, vapour.

Stopped process: close stop valve 8 earlier, close stop valve 1 again, other stop valve is Close All in no particular order.

Embodiment 2, and as shown in Figure 2, its agent structure is substantially the same manner as Example 1.The PLC programmable controller is set, and serve as the main switch board 14 that constitutes with it, to be arranged on the stop valve 8 that stop valve 1, steam on the water return pipeline enters on the pipeline simultaneously and adopt motor-driven valves, the Pressure gauge 15 that Pressure gauge 5, the steam that is arranged on the water return pipeline is entered on the pipeline adopts electric node manometers; With being arranged on thermometer 11 on the water return pipeline, being arranged on the thermometer 24 that steam enters on the pipeline and adopting the electrical nodes thermometers, the stop valve on the inlet pipeline 2 is adopted magnetic valves, constitute intelligent automatic heating plant, its whole process such as embodiment 1.Mainly the switch board 14 that is made of the PLC programmable controller is existing mature technology, and in many device widespread usage, does not do too much explanation at this.Among Fig. 1,2, water inlet and the water outlet in the heating system inserted at A, B two ends respectively.
