Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the description is intended to be illustrative only and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.
Fig. 1 is a schematic structural diagram of a boiler slurry waste heat recovery system according to an embodiment of the present invention.
A schematic structural diagram of a system according to an embodiment of the invention is shown in fig. 1. Fig. 1 is not drawn to scale, with certain details exaggerated and possibly omitted for clarity. The shapes of various regions, layers, and relative sizes and positional relationships therebetween shown in the drawings are merely exemplary, and deviations may occur in practice due to manufacturing tolerances or technical limitations, and a person skilled in the art may additionally design regions/layers having different shapes, sizes, relative positions, as actually required.
As shown in fig. 1, the slurry waste heat recovery system of the boiler comprises: a desulfurizing tower 1, a flash evaporator 3 and a heat pump 4; a sprayer 3-1 is arranged in the flash evaporator 3; the desulfurizing tower 1 is respectively communicated with the spray thrower 3-1 and the evaporation chamber in the flash evaporator 3 to form a slurry circulation loop; the steam outlet of the flash evaporator 3 is communicated with the heat pump 4, and the steam flowing out of the steam outlet exchanges heat with the refrigerant in the heat pump 4, so that the steam is condensed to form condensed water. Wherein, the slurry is positioned at the bottom of the flash evaporator 3, and the sprayer 3-1 is positioned at the middle upper part of the flash evaporator 3.
In a preferred embodiment, the boiler slurry waste heat recovery system further comprises: and the liquid blocking layer 3-2 is arranged in the flash evaporator 3 and is positioned between the sprayer 3-1 and the steam outlet, and is used for absorbing moisture in steam in the flash evaporator 3 and preventing slurry from entering a heat exchange tube in the heat pump to cause problems of deposition, scaling and the like.
Preferably, the liquid barrier layer 3-2 is a baffled liquid barrier. The liquid-blocking layer 3-2 may be provided in one or more layers, and may have a shape of a "herringbone" shape or a "Z" shape.
In a specific embodiment, the heat pump 4 includes an evaporator 4-1 and a condensate drain 6; a pipeline for steam to flow is arranged in the evaporator 4-1, and a refrigerant is accommodated in the evaporator 4-1 and outside the pipeline; one end of the pipeline is communicated with the steam outlet, and the other end of the pipeline is communicated with the condensed water drain pipe 6.
Specifically, the evaporator 4-1 is of a shell-and-tube structure, water vapor flows inside the tubes of the evaporator 4-1, and refrigerant flows inside the shell outside the tubes of the evaporator, so that the water vapor exchanges heat with the refrigerant. After the water vapor is cooled by the heat pump 4, the water vapor is condensed in the tube of the evaporator and is finally discharged through the condensed water discharge pipe 6, and the obtained condensed water can be reused.
In one embodiment, the heat pump 4 is a dead steam type heat pump, so that the resistance of the heat exchange pipe is low. The exhaust heat pump is characterized in that the heat exchange pipes are arranged along the width direction of the heat pump, compared with a common heat pump (the heat exchange pipes are arranged along the length direction of the heat pump), when the gas pressure is lower, the volume is larger under the same mass, and if a flow path of the common heat pump is adopted, on one hand, a circulation channel is short, and the flow speed is large; the high flow rate causes large resistance; meanwhile, along the length direction, the gas flow channel is long, and the resistance is also large. Since the pressure of the exhaust steam is low, if the resistance is too large, the flow is not smooth. Therefore, the dead steam type heat pump adopting the transverse flow has short flow channel on one hand and large flow area on the other hand, so that the resistance of the gas in the heat pump is small. Therefore adopt exhaust steam type heat pump to make the utility model provides an among the waste heat recovery system, at the heat transfer in-process of vapor and refrigerant, do not reduce the grade of waste heat, boiler slurry waste heat recovery system's cost is lower relatively, the use on a large scale of being more convenient for.
In a particular embodiment, a vacuum pump 5 is also included; a vacuum pump 5 is in communication with the vapor line for reducing the pressure in the evaporator 4-1. The flash evaporator 3 and the vacuum pump 5 are positioned at two sides of the evaporator 4-1.
It should be noted that, since evaporator 4-1 is in communication with flash evaporator 3, vacuum pump 5 actually reduces the pressure in evaporator 4-1 and flash evaporator 3 to facilitate rapid movement of water vapor within the system in the direction of evaporator 4-1. Vacuum pump 5 allows the pressure in the evaporator to be slightly lower than the pressure in the flash evaporator, allowing vapor to flow continuously into evaporator 4-1. In addition, the vacuum pump 5 can also be arranged to pump out non-condensable gas in the flash evaporator 3, so that new steam cannot enter the evaporator 4-1 due to the non-condensable gas.
In an optional embodiment, the above-mentioned boiler slurry waste heat recovery system further includes: and the spray pump 2 is arranged on a pipeline connecting the desulfurizing tower 1 and the sprayer 3-1 and is used for conveying the slurry in the desulfurizing tower 1 to the sprayer 3-1.

And compared with the prior art, the process is simple, low in cost and widely applicable.
Further, above-mentioned boiler thick liquid waste heat recovery system still includes: the first pressure pump 9 is arranged on a pipeline communicated with the desulfurization tower 1 and the flash evaporator 3 and is used for conveying the slurry in the flash evaporator 3 to the desulfurization tower 1; alternatively, the bottom surface of the flash evaporator 3 is higher than the liquid level of the slurry in the desulfurization tower 1.
It should be noted that, since the vacuum pump 5 is used to reduce the pressure in the flash evaporator 3, the pressure in the flash evaporator 3 is relatively low. The slurry return pipe 8 may be similar to a vacuum chamber, and the liquid in the slurry return pipe 8 is difficult to flow into the desulfurization tower 1, so that the measures are required to discharge the condensed water in the slurry return pipe 8.
Further, the boiler slurry waste heat recovery system further comprises a second pressure pump 10; the second pressure pump 10 is disposed on the condensed water discharging pipe 6, and is used for discharging the condensed water in the condensed water discharging pipe 6.
It should be noted that, since the vacuum pump 5 is used to reduce the pressure in the flash evaporator 3 and the evaporator 4-1, the pressure in the flash evaporator 3 and the evaporator 4-1 is relatively low. And the condensed water drain pipe 6 is communicated with a pipeline for steam flowing in the evaporator 4-1, the condensed water drain pipe 6 is probably similar to a vacuum cavity due to the action of the vacuum pump 5, and liquid in the condensed water drain pipe 6 is difficult to flow into the normal pressure, so that the measures are needed to be adopted, condensed water in the condensed water drain pipe 6 is discharged, or the position of the condensed water drain pipe 6 is higher than the ground, and the condensed water is discharged by the action of gravity.
It should also be noted that the terms "first", "second" and "third" in the description of the present invention are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

The water vapor passes through the liquid blocking layer 3-2 under the action of the vacuum pump 5 and then enters the evaporator 4-1 of the heat pump 4. The evaporator 4-1 is a shell-and-tube structure, water vapor flows in the tube of the evaporator 4-1, and the outside of the tube is the refrigerant cooling side of the heat pump. Through the refrigeration of the heat pump, steam is condensed in the pipe to obtain condensed water, and the condensed water is discharged through the condensed water discharge pipe 6 and then is recycled.
