Specific embodiment
In order to make present invention solves the technical problem that, use technical solution, the technical effect of acquirement it can be readily appreciated that below
In conjunction with specific attached drawing, a specific embodiment of the invention is described further.
It should be noted that illustrating only part related to the present invention for ease of description, in attached drawing and not all knot
Structure.
With reference to Fig. 2, wall-hung boiler generally comprises cold water inlet pipe 13 and heating water delivery pipe 15, and air and combustion gas pass through pipeline
Input mixes with air after-combustion in combustion chamber 12, heats to main heat exchanger 9, and the flue gas after burning heats secondary heat exchanger 10,
Cold water is inputted by cold water inlet pipe 13, after secondary heat exchanger 10 carries out primary heating and main heat exchanger 9 carries out reheating, through adopting
Warm water delivery pipe 15 flows out.Heating water delivery pipe can access heating equipment and use for indoor heating, can also be with indoor hot water
Device 12 is connected to, and provides hot water for life, and user is facilitated to wash one's face and rinse one's mouth use.Flue gas can generate when carrying out heat exchange with time heat exchanger 9
Condensed water.In the prior art, the condensed water is by being connected to the condensed water outlet pipe 14 of time 9 lower end of heat exchanger by condensed water itself
Gravity naturally drains, and since water is few, flow velocity is low, will appear drainpipe icing phenomenon in cold weather.
Aiming at the problem that above-mentioned condensation water freezing, the present invention provides it is a kind of can collection to condensed water and discharge carry out
The drainage arrangement of temperature and pressure control, which is used in conjunction with wall-hung boiler, to solve above-mentioned condensation
The problem of water freezing.
Fig. 1 is one embodiment of drainage arrangement of the present invention.The drainage arrangement include a water tank 2, the upper end with it is cold
Condensate drainpipe 1 is connected to, and lower end is equipped with drainpipe 3.Heat-exchanger rig 4 is equipped in water tank 2, which uses coil pipe knot
The water inlet of structure, coil pipe upper end is connected to by pipeline and electronic valve 6 with heating water outlet pipe 5, and the water outlet of coil pipe lower end passes through
Pipeline is directly connected to heating water outlet pipe 5.Drainpipe 3 is equipped with drain valve 7, which can use pressure valve.Water storage
Temperature sensor 8 is additionally provided on tank 2
Electronic valve 6 is used to open or close the channel between the coil pipe of heat-exchanger rig.Heat-exchanger rig 4 acts through introducing
Hot water heats the condensed water of 2 the inside of water tank.The effect of pressure valve is the condensation hydraulic pressure according to 2 the inside of detection water tank
The discharge of power size control condensed water.Temperature sensor 8 is used to detect the water temperature in water tank 2.The effect of water tank 2 is to receive
The condensed water that collection, storage are flowed by condensate draining pipe 1.
Dotted line frame inner part is the schematic diagram of drainage arrangement of the present invention in Fig. 2.When drainage arrangement is connect with wall-hung boiler, only
It needs for the heating water delivery pipe 15 of wall-hung boiler to connect with the heating water outlet pipe 5 of drainage arrangement, then wall-hung boiler condensed water is gone out
Water pipe 14 is connect with the condensate draining pipe 1 of drainage arrangement, and operation is very easy for installation.
The working principle of drainage arrangement: the condensed water that the flue gas and heat exchanger of external wall-hung boiler carry out generation when heat exchange is logical
It crosses condensate draining pipe 1 and flows into storage in water tank 2.8 real-time detection water temperature of temperature sensor on water tank 2, works as water
When temperature is higher than limit value T, electronic valve 6 is in close state；When water temperature is lower than limit value T, there are when icing hidden danger, electronic valve 6
Open valve is introduced in heating hot water to coil pipe from heating water outlet pipe 5, makes water storage by the heat exchange of hot water and condensed water
The temperature of condensed water increases in tank 2, prevents the condensed water in water tank 2 and drainpipe 3 from being influenced to freeze by microthermal climate, guarantees
The normal use of the drainage arrangement and wall-hung boiler connected to it.
When the water temperature in water tank 2 is increased above limit value T, electronic valve 6 is closed, and heating terminates.
With reference to Fig. 3, the control method of drainage arrangement provided by the invention the following steps are included:
Step 1. passes through the water temperature in 8 real-time detection water tank 2 of temperature sensor；
Step 2. closes electronic valve 6 when water temperature is higher than limit value T；When water temperature is lower than limit value T, electronic valve 6 is opened, from
Heating water outlet pipe 5 introduces hot water to coil pipe and heats for condensed water；
Step 3. is when water temperature heating is to when being higher than limit value T, and electronic valve 6 is closed, and heating terminates.
In the embodiment, limit value T is preferably set to 5 degree.
Pressure valve on 2 bottom discharge pipe 3 of water tank can constant testing its hydraulic pressure for being born, when detection hydraulic pressure is big
When setting value, pressure valve is opened, and water tank 2 drains, and when detecting hydraulic pressure less than setting value, pressure valve is closed, and water tank 2 exists
Water stored state.
As shown in figure 4, include: 7 hydraulic pressure of real-time detection drain valve the step of condensed water elimination in water tank 2, when detecting
When hydraulic pressure is greater than the set value, drain valve 7 is opened, and water tank 2 is drained；When detecting that hydraulic pressure is less than setting value, drain valve 7
It closes, water tank 2 carries out water storage.
Above embodiments and attached drawing are only used to illustrate the technical scheme of the present invention, and are not constituted a limitation of the present invention, and are answered
When explanation, those of ordinary skill in the art can modify to technical solution documented by previous embodiment or right
Part of or all technical features are equivalently replaced, and these are modified or replaceed should be included in claims of the present invention
In the range of protection.
