Abstract
The utility model relates to a water preheating apparatus for a boiler, which is provided with a water tank (1) and a water pump (9), wherein a water inlet (7) and a water outlet (8) are arranged on the water tank (1); the water inlet (7) is connected with a water source; the water outlet (8) is connected with the inlet of the water pump (9); the outlet of the water pump (9) is connected with a water supplying port of the boiler; a heating steam pipe (2) is accessed in the water tank. The water preheating apparatus for a boiler of the utility model can utilize steam tail gas which is usually discharged for preheating supplied water for the boiler; thereby, the utilization rate of heat energy can be increased; the utility model is good environmental protection product.
Description
Technical field
The utility model relates to a kind of preheating device, particularly a kind of preheating device that utilizes the hot exhaust gas Steam Heating boiler feed water of iron.
Background technology
At present, woollen milol, the clothing factory utilizes boiler heating water generates steam, when steam through the iron pressing of scalding on the platform, iron must have an air inlet pipe and a blast pipe, air inlet pipe is the steam from boiler, steam steams clothes through the iron ejection and scalds, blast pipe will be to run into the water discharge that low temperature generates in the iron with in the pipeline, will put some gas when draining could discharge water, and common this steam also is waste gas in tail gas, so frequent discharging tail gas can cause the significant wastage of energy.
And simultaneously, above-mentioned boiler water-filling replenishes through water pump by its water tank, and the water that is replenished is normal-temperature water, normally 10-20 ℃ of temperature, cause one side tail gas to waste like this, and boiler need more heat that water is heated on the other hand, produces steam.Will cause the waste of energy like this
Summary of the invention
The purpose of this utility model provides a kind of tail gas steam that rationally utilizes, and particularly the tail gas steam of iron discharge carries out the boiler feed water preheating device of preheating to boiler water-filling, thereby can overcome the defective of energy dissipation in the prior art.
In order to achieve the above object, a kind of boiler feed water preheating device of the present utility model, be provided with water tank, water pump, water inlet and delivery port are set on described water tank, and water inlet is connected with the water source, and delivery port is connected with the water pump import, the outlet of water pump is connected with the additional mouth of a river of boiler, connects the heating steam pipe in described water tank.
The import of described steam pipe is connected with the iron blast pipe.
Boiler feed water preheating device of the present utility model can be used for the steam tail gas of discharging usually the supplementing water that preboiler is used, thereby has improved the utilization rate of heat energy.Can utilize woollen milol especially, the supplementing water that the tail gas preboiler that clothing factory's iron is discharged is used can be energy-conservation, and consumption reduction is extraordinary environment-friendly products.
Description of drawings
Fig. 1 represents the structural representation of the utility model embodiment.
The specific embodiment
With reference to accompanying drawing, will be described in detail the specific embodiment of the present utility model.
Of the present utility modelly can utilize the existing water tank 1 of boiler, as shown in Figure 1, be connected to heating steam pipe 2 on the water tank 1 of boiler, middle logical heating steam is heated the water in the water tank 1.Heating steam is the steam tail gas of using from the tail gas of iron blast pipe or other equipment, and this heating steam steam pipe 2 of flowing through injects the water in the water tank, with process that water contacts in water is heated.
For augmentation of heat transfer, described steam pipe 2 preferably inserts below the water tank 1 interior water surface.
Because common existing boiler feed water case 1 and water pump 9 are supporting with boiler, water tank 1, water pump 9 can not tolerate too high temperature, if and the temperature in the water tank is too high, may damage water tank, water pump, and water tank can be uncovered equipment, the steam of its top is too big, also not really safe, so control the temperature in the water tank, on the boiler feed water preheating device, be provided with temperature controller 4, liquid level in water tank 1 is to have temp probe 3, the output of temp probe 3 is connected with the input of temperature controller 4, on the inlet tube 5 of steam pipe 2 magnetic valve 6 is installed, and described magnetic valve 6 is connected with the output of temperature controller 4, accept the instruction of temperature controller 4, the input by magnetic valve 6 control steam with close.When temperature was higher than setting value, magnetic valve 6 was closed in temperature controller 4 indications automatically, and when temperature was lower than setting value, magnetic valve 6 was opened in temperature controller 4 indications automatically, begins heating.Desired temperature can determine that preferably temperature is controlled at less than 100 ℃ according to the appointed condition of concrete water tank 1 and water pump 9.
Described magnetic valve 6 can be two mouthfuls of commercially available two magnetic valves, its structure as shown in Figure 1, be shaped on valve import 22, valve outlet port 23, described valve outlet port 23 is bent upwards, the upper end has osculum 24, the upper end of osculum 24 is provided with spool 20, described spool 20 outer most surrounding coils, the sealing gasket 21 of described spool 20 bottoms is relative with described osculum, when magnetic valve 6 is opened, spool 20 is risen by magnetic attraction, the sealing gasket 21 of spool 20 bottoms breaks away from osculum 24, and valve import 22 is connected with valve outlet port 23, the beginning air feed; Otherwise when closing magnetic valve 6, spool 20 falls after rise, closes osculum, stops heating.Because the temperature of tail gas is higher,, and need make with resistant to elevated temperatures materials such as silica gel so the material of sealing gasket 21 can not be used conventional rubber.
Boiler feed water preheating device of the present utility model can be used for the steam tail gas of discharging usually the supplementing water that preboiler is used, thereby has improved the utilization rate of heat energy.
