Description

Technical Field

[0001] This utility model relates to the field of air heat exchange technology for fresh air systems, specifically a cooling atomizer based on an ethylene glycol heat recovery system. Background Technology

[0002] Heat recovery in a fresh air system is a form of heat recovery set between the fresh air unit and the exhaust air unit. It utilizes the temperature difference between outdoor fresh air and indoor exhaust air, and drives the heat exchange medium to circulate between the fresh air heat exchanger and the exhaust air heat exchanger through a circulating pump, thereby realizing the recovery of exhaust air energy and achieving the purpose of energy saving and consumption reduction.

[0003] In summer, the ethylene glycol heat recovery system discharges cold air from the room through the exhaust side of the fresh air system. The discharged cold air passes through the heat exchange tubes on the exhaust side of the ethylene glycol heat recovery system. The ethylene glycol heat exchanger flowing inside the heat exchange tubes on the exhaust side of the ethylene glycol heat recovery system releases heat and cools down. Driven by the circulation pump, it circulates to the fresh air side of the fresh air system for heat exchange. The high-temperature gas on the fresh air side exchanges heat with the low-temperature ethylene glycol heat exchanger on the fresh air side of the ethylene glycol heat recovery system, thereby reducing the temperature of the fresh air and delivering it to the room.

[0004] In the summer, when the ethylene glycol heat recovery system is used for heat exchange and cold recovery, the heat exchange tubes on the exhaust side of the system rely solely on simple air contact for heat exchange. The heat exchange efficiency is not improved by the assistance of other media that accelerate heat exchange (such as water evaporation). The heat exchange effect needs to be further improved.

[0031] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0032] As Figures 1 to 9 shown, a cooling atomizer based on a glycol heat recovery system, comprising a connection frame 11 and a main pipeline 21, the main pipeline 21 is transitionally connected with the connection frame 11 through a supporting rod 12, the main pipeline 21 is hinged on the supporting rod 12, a plurality of branch pipelines 22 are also communicatively arranged on the main pipeline 21, a plurality of atomizing nozzles 23 are uniformly arranged on the branch pipeline 22.

[0033] In use, the main pipe 21 is connected to an external water source, such as a pressurized water pipe, and the external water source can be pressurized by a booster pump and introduced into the main pipe 21. The main pipe 21 is provided with a water inlet 221, and the external water source enters the main pipe 21 through the water inlet 221. The water flow enters the branch pipe 22 and the atomizing nozzle 23 in turn after passing through the main pipe 21, and is finally atomized and sprayed by the atomizing nozzle 23 towards the heat exchange pipe 51 on the exhaust side of the glycol heat recovery system. The evaporation of water further reduces the surface temperature of the heat exchange pipe 51 on the exhaust side of the glycol heat recovery system, thereby increasing the refrigeration effect.

[0034] In the prior art, the outer side of the heat exchange pipe 51 is often provided with fins 52 to increase the overall heat conduction performance of the heat exchange pipe 51 and improve the heat exchange efficiency. The heat exchange pipe 51 and the fins 52 are integrated and installed as a whole by a mounting plate 53, and the mounting plate 53 is open at the extension direction of the fins 52 to form an air duct for air to pass through, thereby facilitating air flow through the heat exchange.

[0035] In this embodiment, the connecting frame 11 is fixed to the mounting plate 53 and located at one end of the air inlet of the air duct.

[0036] As a specific embodiment, as shown in Figure 4 The outer side of the support rod 12 is sleeved with a sliding sleeve 31, the sliding sleeve 31 is slidingly arranged on the outer side of the support rod 12, and the main pipe 21 is rotatably arranged on the sliding sleeve 31. By adjusting the position of the sliding sleeve 31, the distance between the main pipe 21 and the connecting frame 11 can be further adjusted, so as to adjust the distance between the atomizing nozzle 23 and the connecting frame 11. The connecting frame 11 is used to connect with the heat exchange pipe 51 on the exhaust side of the glycol heat recovery system, so that the distance between the atomizing nozzle 23 and the heat exchange pipe 51 can be adjusted. Through the above distance adjustment, the spraying effect of the atomized water can be adjusted. When the distance is short, the spraying area is concentrated, and when the distance is far, the spraying area is spread. The distance can be adjusted to a suitable distance where the atomized water can be sprayed to the heat exchange pipe 51 completely according to the actual shape of the heat exchange pipe 51.

[0037] In this embodiment, the sliding sleeve 31 is provided with a positioning bolt 33, and the sliding sleeve 31 is fixed on the support rod 12 by tightening the positioning bolt 33. Therefore, when the position of the sliding sleeve 31 needs to be adjusted, the positioning bolt 33 is loosened, and the specific position of the sliding sleeve 31 can be adjusted. When the position of the sliding sleeve 31 does not need to be adjusted, the positioning bolt 33 is tightened to fix the sliding sleeve 31 relative to the support rod 12.

[0038] As a specific embodiment, as shown in Figure 5 The sliding sleeve 31 is provided with an axle seat 32, and the main pipe 21 is rotatably arranged on the axle seat 32 through an axle (not shown in the figure).

[0039] Preferably, the main pipe 21 is vertically arranged, and the upper and lower ends of the main pipe 21 are correspondingly provided with support rods 12 and sliding sleeves 31, and the upper and lower ends of the main pipe 21 are respectively rotationally connected with the corresponding sliding sleeves 31 through rotating shafts.

[0040] Preferably, as shown in Figures 6 to 9 the main pipe 21 is arranged on both sides of the connecting frame 11 in a symmetrical manner, and the two main pipes 21 are fixedly connected through limiting members between the horizontally corresponding branch pipes 22.

[0041] As a specific embodiment, the limiting member includes a limiting hoop 41 and a limiting head 42, the limiting hoop 41 and the limiting head 42 are respectively fixed on the two horizontally corresponding branch pipes 22, and the limiting head 42 is clamped in the corresponding limiting hoop 41.

[0042] Specifically, the limiting hoop 41 includes a first sleeve head 411 and a clamping hoop part 412, and the limiting hoop 41 is sleeved on the corresponding suspended end of the branch pipe 22 through the first sleeve head 411; the limiting head 42 includes a second sleeve head 421, and the limiting head 42 is sleeved on the corresponding suspended end of the branch pipe 22 through the second sleeve head 421; the top end of the first sleeve head 411 is provided with the clamping hoop part 412, the top end of the second sleeve head 421 is provided with a plug part 422, and the plug part 422 is inserted into the inside of the clamping hoop part 412.

[0043] Specifically, the plug part 422 is arranged in a cylindrical structure, the clamping hoop part 412 is arranged in a pincer structure, the inside of the clamping hoop part 412 includes an accommodating cavity part 413 with the same diameter as the plug part 422, one side of the accommodating cavity part 413 is provided with an entrance part 414 arranged in an open manner and communicating with the accommodating cavity part 413, and a limiting part 415 is arranged between the accommodating cavity part 413 and the accommodating cavity part 413. The plug part 422 enters the accommodating cavity part 413 through the entrance part 414 and the limiting part 415 in sequence, and the space at the limiting part 415 is slightly smaller than the diameter of the plug part 422, so that the plug part 422 is inserted into the corresponding accommodating cavity part 413 after the deformation of the limiting part 415 caused by external force, and the corresponding limiting part 415 is clamped and fixed after the plug part 422 is inserted into the accommodating cavity part 413, thereby forming a fixed connection between the two horizontally corresponding branch pipes 22. Similarly, the plug part 422 can also be pulled out of the accommodating cavity part 413 by external force, thereby canceling the fixed connection between the two horizontally corresponding branch pipes 22. After the fixed connection between the corresponding branch pipes 22 is canceled, the main pipe 21 can be rotated and the branch pipes 22 can be moved away from the heat exchange pipes 51 (as shown in Figure 2 ). In this way, the branch pipes 22 will not block the heat exchange pipes 52 and the fins 52, thereby facilitating the maintenance and cleaning of the heat exchange pipes 52 in the later stage.

[0044] It will be apparent to those skilled in the art that the application is not limited to the details of the above-exemplified embodiments and that the application can be implemented in other particular forms without departing from the spirit or essential characteristics of the application. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the application being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. No feature of the application is considered critical unless it is expressly stated in the claims.
