Description

Technical Field

[0001] The utility model relates to the technical field of cooling equipment, in particular to a cooling equipment capable of being cleaned online. Background Art

[0002] Cooling equipment such as sealed cooling towers utilizes tubular heat exchangers within the tower, ensuring effective cooling through heat exchange between circulating air and spray water and the chemical medium. Due to the closed-loop system, various sediments are present in various chemical media, particularly heat treatment, quenching fluids, and oil-water. In actual production, impurities in the chemical medium can cause precipitation within the tubular heat exchanger tubes, blocking the pipes, increasing thermal resistance, and reducing the thermal performance of the tube bundle. Prolonged cleaning can render the cooling tower useless, necessitating regular cleaning of the tubular heat exchanger tubes.

[0003] The existing technology usually involves manually cleaning tubular heat exchangers, but there are multiple groups of tubular heat exchangers (for example, there are 40 groups of tubular heat exchangers in the machine body). During cleaning, the cooling equipment must be stopped, which affects production. In addition, manual cleaning is inconvenient and requires a lot of labor costs. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] The present invention provides an online-cleanable cooling device, comprising a housing 1, a water inlet pipe, a water outlet pipe, a first cleaning pipe 2, a second cleaning pipe 3, a plurality of first three-way valves 4, a plurality of second three-way valves 5, and a plurality of tubular heat exchangers 6. The plurality of tubular heat exchangers 6 are disposed within the housing 1, with one end of each tubular heat exchanger 6 connected to a first three-way valve 4, and the other end of each tubular heat exchanger 6 connected to a second three-way valve 5. Each first three-way valve 4 is also connected to the water inlet pipe and the first cleaning pipe 2, and each second three-way valve 5 is also connected to the water outlet pipe and the second cleaning pipe 3. It is understood that the number of first three-way valves 4 and second three-way valves 5 is the same as the number of tubular heat exchangers 6.

[0025] Preferably, the present invention further includes a cleaning tank 7 and a cleaning pump 8, disposed outside the housing 1. The outlet of the cleaning tank 1 is connected to the inlet of the cleaning pump 8, which is in turn connected to the inlet of the first cleaning pipe 2, which is in turn connected to the first three-way valve 4. The inlet of the second cleaning pipe 3 is connected to the second three-way valve 5, and the outlet of the second cleaning pipe 3 is connected to the inlet of the cleaning tank 7. The cleaning tank 7 stores a cleaning medium such as cleaning liquid or rubber balls for cleaning the interior of the tubular heat exchanger 6. The cleaning pump 8 is used to better deliver the cleaning medium in the cleaning tank 7 into the tubular heat exchanger 6 to enhance the cleaning effect.

[0026] It can be understood that the working principle of the online cleaning cooling device of the present invention is as follows: (1) When the cooling device is running, the first three-way valve 4 is rotated to the water inlet pipe passage so that one end of the tubular heat exchanger 6 is connected to the water inlet pipe, and the second three-way valve 5 is rotated to the water outlet pipe passage so that the other end of the tubular heat exchanger 6 is connected to the water outlet pipe, so that the chemical medium can enter the tubular heat exchanger 6 from the water inlet pipe for heat exchange, and the chemical medium is finally discharged from the water outlet pipe. (2) If the tubular heat exchanger 6 needs to be cleaned, it is only necessary to rotate the first three-way valve 4 and the second three-way valve 5 to the cleaning pipe passage so that one end of the tubular heat exchanger 6 is connected to the first cleaning pipe 2 and the other end of the tubular heat exchanger 6 is connected to the second cleaning pipe 3. At this time, the cleaning medium such as cleaning liquid or rubber balls is sent into the tubular heat exchanger 6 through the first cleaning pipe 2 by the cleaning pump 8, and the cleaning medium is finally discharged from the second cleaning pipe 3, thereby achieving the cleaning of a single group of tubular heat exchangers 6. (3) Since the cooling equipment is provided with multiple groups of tubular heat exchangers 6, taking 40 groups of tubular heat exchangers as an example, when cleaning is required, 5 groups of tubular heat exchangers can be cleaned first according to the above cleaning process. Among them, during the cleaning process of the 5 groups of tubular heat exchangers, the remaining 35 groups of tubular heat exchangers are in normal operating state. After the cleaning of the 5 groups of tubular heat exchangers is completed, the normal operating state can be restored by rotating the three-way valve accordingly. Then, the cleaning of the other 5 groups of tubular heat exchangers is carried out in the same way until the cleaning of all the tubular heat exchangers is completed. In the above manner, the present invention can realize online cleaning without stopping the operation of the cooling equipment as a whole, and the cleaning is convenient and quick, and can be carried out without professional cleaning personnel. Of course, the number of tubular heat exchangers to be cleaned each time can also be set according to the specific cleaning needs, and there are no excessive restrictions here.

[0027] Preferably, the outlet of the first cleaning pipe 2 is connected to each first three-way valve 4 via a first connecting member 9, and the inlet of the second cleaning pipe 3 is connected to each second three-way valve 5 via a second connecting member 10. In addition, the present invention further includes a third connecting member 11, a fourth connecting member 12, a first flange 13, and a second flange 14. The first flange 13 and the second flange 14 are spaced apart on the outer wall of the body 1. The water inlet pipe is connected to each first three-way valve 4 via the first flange 13 and the third connecting member 11, and the water outlet pipe is connected to each second three-way valve 5 via the second flange 14 and the fourth connecting member 12. It can be understood that the first connecting member 9, the second connecting member 10, the third connecting member 11, and the fourth connecting member 12 are each provided with multiple connection ports for connecting to each first three-way valve 4 or each second three-way valve 5, respectively.

[0028] The present invention may also include a spray assembly and a spray pump 15. The spray assembly is arranged in the body 1 and above the tubular heat exchanger 6. The spray pump 15 is connected to the spray assembly, wherein the spray assembly includes a spray pipe and a spray head. Water is sprayed to the tubular heat exchanger 6 through the spray assembly for heat exchange.

[0029] In addition, preferably, the body 1 is provided with an air inlet 16 and an air outlet, so that the circulating air enables the tubular heat exchanger 6 to achieve heat exchange. Further, the air inlet 16 is located on the front side of the body 1, and the air outlet is located on the upper side of the body 1, and a fan 17 is provided at the air outlet.

[0030] Compared with the prior art, the present invention provides a cooling device that can be cleaned online, which has the following beneficial effects: the present invention connects a first cleaning pipe and a second cleaning pipe to the two ends of the tubular heat exchanger through a three-way valve. When the equipment is running, the three-way valve is rotated to the water inlet pipe path, allowing the chemical medium to enter the tubular heat exchanger from the water inlet pipe and finally exit from the water outlet pipe; if the tubular heat exchanger needs to be cleaned, it is only necessary to rotate the three-way valve to the cleaning pipe path, allowing cleaning liquid or a cleaning medium such as a rubber ball to enter the tubular heat exchanger through the first cleaning pipe for cleaning and finally exit from the second cleaning pipe, thereby achieving the cleaning of a single group of tubular heat exchangers. The present invention solves the cleaning problem of the tubular heat exchanger by providing a three-way valve to achieve switching between cleaning and use at any time, thereby solving the problem of cleaning the tubular heat exchanger. There is no need to stop the cooling equipment for cleaning, which can better ensure the normal operation of the cooling equipment. Cleaning is convenient and can be performed without the need for professional cleaning personnel, which can reduce labor costs.
