Abstract
The utility model discloses a device for preheating boiler replenishing water by using heat energy of power equipment. A cooling water outfall sewer a of the power equipment is respectively communicated with a cooling tower and a cooling water inlet of a heat exchanger; a cooling water outlet of the heat exchanger is respectively communicated with the cooling tower and a softened water tank through a cooling water outlet pipe g; the cooling tower is communicated with the softened water tank through a first water pipe j, and the softened water tank is communicated with the power equipment through a second water pipe n; and a softened water inlet pipe d is communicated with a softened water inlet of the heat exchanger, and a softened water outlet of the heat exchanger is communicated with a deoxidization tank through a softened water outlet pipe e. According to the device, the heat exchanger exchanges heat between high-temperature cooling water discharged by the power equipment and low-temperature softened water, then high-temperature softened water is discharged and deoxidized, and the deoxidized water is supplied to a boiler, so that the temperature of the softened water used by the boiler can be effectively raised, the used amount of steam during deoxidization can be reduced, and the energy consumption is reduced.
Description
Technical field
The utility model relates to a kind of device with the moisturizing of power-equipment heat energy preboiler.
Background technology
Equipment operations such as the power-equipment of tobacco enterprise such as refrigeration machine, vavuum pump, air compressor machine can be supervened heat, and these heat need utilize cooling water to take away, and power-equipment is cooled off.Generally about 35 ℃, because cooling water temperature is not very high, its energy that carries seldom utilizes the cooling water leaving water temperature.Be lost in the air through the heat of cooling tower with cooling water, cooling water temperature is dropped to about 25 ℃ from about 35 ℃, cooling water comes back to power-equipment the used heat that power-equipment produces is taken away, and so moves in circles.Boiler heating power just can reach good deaerating effect except that oxygen demand is heated to 104 ℃ with demineralized water, and general thermoplastic water is used Steam Heating, will consume a large amount of steam like this, wastes energy.
The utility model content
The purpose of the utility model provides a kind of device with the moisturizing of power-equipment heat energy preboiler, effectively utilizes power-equipment cooling water heat, reduces energy resource consumption.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of device with the moisturizing of power-equipment heat energy preboiler; The cooling water outfall sewer a of power-equipment is communicated with cooling tower and heat exchanger cooling water inlet respectively, and the heat exchanger cooling water outlet is communicated with cooling tower and softening pond respectively through cooling water outlet pipe g; Cooling tower is communicated with softening pond through the first water pipe j, and softening pond is communicated with power-equipment through the second water pipe n; Demineralized water water inlet pipe d is communicated with heat exchanger demineralized water water inlet, and heat exchanger demineralized water delivery port is communicated with deaeration pump through demineralized water outlet pipe e.
Be connected with the bypass pipe that has valve between described demineralized water water inlet pipe d and the demineralized water outlet pipe e.
In the utility model; The high-temperature cooling water and the low temperature softening water that utilize heat exchanger that power-equipment is discharged carry out heat exchange; The higher demineralized water of discharge temperature carries out deoxygenation and boiler of feeding again to be used; Can effectively improve boiler of feeding use demineralized water temperature, the steam use amount in the time of can reducing deoxygenation cuts down the consumption of energy.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1; A kind of device with the moisturizing of power-equipment heat energy preboiler; The cooling water outfall sewer a of power-equipment 1 is communicated with the cooling water inlet 41 of cooling tower 2 and heat exchanger 4 respectively, and the cooling water outlet 42 of heat exchanger 4 is communicated with cooling tower 2 and softening pond 3 respectively through cooling water outlet pipe g; Cooling tower 2 is communicated with softening pond 3 through the first water pipe j, and softening pond 3 is communicated with power-equipment 1 through the second water pipe n; Demineralized water water inlet pipe d is communicated with the demineralized water water inlet 43 of heat exchanger 4, and the demineralized water delivery port 44 of heat exchanger 4 is communicated with deaeration pump 5 through demineralized water outlet pipe e.Be connected with the bypass pipe f that has valve between demineralized water water inlet pipe d and the demineralized water outlet pipe e, when heat exchanger 4 breaks down, can open the valve on the bypass pipe f, demineralized water will directly get into deaeration pump 5 without heat exchanger 4 and carry out the use of deoxygenation boiler of feeding.
In the utility model, all be provided with valve on each water pipe according to demand.The higher cooling water of the temperature that power-equipment 1 is discharged gets into heat exchanger 4 and carries out heat exchange from the lower demineralized water of the temperature of demineralized water water inlet pipe d through cooling water outfall sewer a; Cooling water after the cooling enters to soften pond 3 (if the cooling water temperature after the cooling is still when higher; Advancing cooling tower 2 carries out getting into power-equipment 1 again behind the reducing temperature twice); Demineralized water after heat exchanger 4 heats up gets into deaeration pump 5 through demineralized water outlet pipe e; Steam gets into deaeration pump 5 through steam pipe k and carries out deoxygenation, and the demineralized water after the deoxygenation gets into the boiler boiler of feeding through the 3rd water pipe m and uses.
