Description

Technical Field

[0001] The utility model relates to the technical field of energy-saving and environmental protection equipment, in particular to a secondary steam recovery energy-saving and environmental protection device. Background Art

[0002] Steam contains a large amount of heat. Direct discharge will cause heat loss and subsequent waste. Therefore, it is generally necessary to utilize and store the excess heat to achieve the purpose of energy saving and environmental protection.

[0003] The utilization of steam is generally achieved through a heat exchanger. A spiral gas guide pipe is set in the heat exchange box, and the steam is introduced into the gas guide pipe. The heat emitted from the gas guide pipe is used to heat the liquid in the heat exchange box, thereby achieving the purpose of heat recovery. However, this method has certain shortcomings. First, there is a pipe separating the steam and the liquid, and the liquid cannot be directly heated, which reduces the heating effect. Secondly, the steam is directly discharged in the guide pipe and cannot fully contact the liquid. The contact time is short and the heat in the steam cannot be fully absorbed. Therefore, the current energy-saving device has the defects of low energy-saving efficiency and subsequent waste of energy consumption, and needs to be improved. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example

[0023] like Figure 1 , Figure 2 and Figure 3As shown, a secondary steam recovery energy-saving and environmental protection device proposed in one embodiment of the utility model includes an insulated box 1, a steam inlet pipe 12 is connected to the bottom of one side of the insulated box 1, and a first horizontal guide plate 5 and a second horizontal guide plate 6 are fixedly connected to the inner side of the insulated box 1, a first horizontal guide gap 7 is opened on one side of the first horizontal guide plate 5, a second horizontal guide gap 3 is opened on the side of the second horizontal guide plate 6 away from the first horizontal guide gap 7, and a first vertical guide plate 4 and a second vertical guide plate 10 are fixedly arranged between two adjacent first horizontal guide plates 5 and second horizontal guide plates 6, a first vertical guide gap 2 is opened on one side of the first vertical guide plate 4, and a second vertical guide gap 9 is opened on the side of the second vertical guide plate 10 away from the first vertical guide gap 2.

[0024] It should be noted that the heat preservation box 1 is the external protection part of the device. By arranging a steam inlet pipe 12 on one side of the heat preservation box 1, there is water vapor in the steam inlet pipe 12, and the steam is discharged into the inner side of the heat preservation box 1 through the steam inlet pipe 12, so as to realize the heating of the water inside the heat preservation box 1 and recover the heat of the steam. By arranging the first transverse guide plate 5 and the second transverse guide plate 6 at intervals on the inner side of the heat preservation box 1, the layered arrangement can extend the transmission path of the steam and improve the utilization rate of the steam heat. By arranging the first transverse guide notch 7 on one side of the first transverse guide plate 5 and the second transverse guide notch 3 on one side of the second transverse guide plate 6, the steam can pass through the first transverse guide notch 7 and the second transverse guide notch 6. The guide gap 3 is transmitted to the upper layer to realize the transmission and movement of steam. By arranging the first vertical guide plate 4 and the second vertical guide plate 10 between the two first horizontal guide plates 5 and the second horizontal guide plates 6, the discharge of steam can be further delayed, the contact time between steam and water can be increased, and then the heat in the steam can be absorbed as much as possible to improve the heat recovery efficiency. By arranging the first vertical guide gap 2 on one side of the first vertical guide plate 4 and the second vertical guide gap 9 on one side of the second vertical guide plate 10, the arrangement of the first vertical guide gap 2 and the second vertical guide gap 9 can realize the transmission of steam, so that the steam is transmitted between different first vertical guide plates 4 and second vertical guide plates 10 in turn.

[0025] like Figure 1 and Figure 2 As shown, in some embodiments, a guide area is formed between the first vertical guide plate 4, the first transverse guide plate 5, the second transverse guide plate 6 and the second vertical guide plate 10, and equidistantly distributed orifice plates 8 are arranged in the guide area, and array-distributed guide holes 11 are opened on the orifice plates 8.

[0026] It should be noted that the steam is transmitted in the guide area. By arranging a perforated plate 8 in the guide area, the perforated plate 8, on the one hand, supports the first vertical guide plate 4, the first transverse guide plate 5, the second transverse guide plate 6 and the second vertical guide plate 10. Secondly, the perforated plate 8 can disperse the steam bubbles through the guide holes 11, so that the steam is evenly in contact with the water, and then effectively absorbs the heat in the steam.

[0027] like Figure 1 As shown, in some embodiments, a guide cavity is formed between the inner wall of the heat preservation box 1 and the first vertical guide gap 2 , the second transverse guide gap 3 , the first transverse guide gap 7 and the second vertical guide gap 9 .

[0028] It should be noted that the steam is transmitted through the guide cavity in sequence, so as to realize the transmission of steam in different guide areas and the transmission between different layers of the first transverse guide plates 5 and the second transverse guide plates 6, so as to realize the transmission of steam from bottom to bottom.

[0029] like Figure 1 and Figure 3 As shown, in some embodiments, the upper portion of the heat preservation box 1 is connected to an exhaust pipe 16 , and a protective cap 15 is fixed to a bracket disposed on the top of the exhaust pipe 16 .

[0030] It should be noted that the steam transmitted from bottom to top is discharged through the exhaust pipe 16 , and a protective cap 15 is provided on the upper part of the exhaust pipe 16 to prevent foreign matter from entering the exhaust pipe 16 .

[0031] like Figure 1 and Figure 3 As shown, in some embodiments, an upper portion of one side of the insulated box 1 is connected to a water inlet pipe 17, and a bottom portion of the insulated box 1 located between the first vertical guide plate 4 and the first horizontal guide plate 5 is connected to a water outlet pipe 13, on which a valve 14 is installed.

[0032] It is explained that high-temperature steam enters one side of the first vertical guide plate 4 through the steam inlet pipe 12, and is then transmitted along the guide cavity and the guide area in sequence, and is finally discharged through the exhaust pipe 16. Water enters the upper inner part of the insulated box 1 through the water inlet pipe 17, and the flow direction of the water is opposite to the flow direction of the steam, which can accelerate the contact between water and steam, and then accelerate the recovery of steam heat. By arranging a water outlet pipe 13 at the bottom of the insulated box 1, the water after absorbing heat is discharged through the water outlet pipe 13, and the setting of the valve 14 can realize the water outlet control of the water outlet pipe 13.

[0033] like Figure 1 As shown, in some embodiments, a heat preservation layer is provided on the inner wall of the heat preservation box 1.

[0034] It should be noted that the provision of the heat-insulating layer can achieve heat-insulating treatment of the heat-insulating box 1 and prevent heat from dissipating.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
