Description

Technical Field

[0001] This utility model relates to the field of industrial waste gas treatment technology, and in particular to a high-efficiency counter-current microchannel condenser. Background Technology

[0002] With the development of environmental protection and energy-saving technologies, in the process of industrial waste gas treatment and waste heat recovery, it is necessary to quickly cool and purify high-temperature and high-humidity waste gas, and at the same time recover heat to reduce energy consumption. This requires the use of condensers.

[0003] In practical use, condensers with similar structures still have many defects. For example, traditional condensers mostly adopt co-current heat exchange or unidirectional heat exchange modes, with small gas-liquid contact area and short heat exchange time, resulting in insufficient heat recovery. At the same time, traditional condensers lack efficient filtration and flow guidance design for condensate, which can easily lead to impurities entering the cooling system, causing pipe blockage and scale deposition. Therefore, it is necessary to design a high-efficiency counter-current microchannel condenser. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a high-efficiency counter-flow microchannel condenser.

[0005] This utility model is achieved using the following technical solution: a high-efficiency counter-current microchannel condenser, comprising a condensation assembly, the condensation assembly including a condensation chamber, the outer surface of the condensation chamber having an exhaust gas inlet, the interior of the condensation chamber having a sedimentation chamber and a cooling chamber, a circulating water pump fixedly connected to the outer surface of the condensation chamber, an inlet pipe fixedly connected to the input end of the circulating water pump, a delivery pipe fixedly connected to the output end of the circulating water pump, a spray pipe fixedly connected to the bottom of the delivery pipe, and a fan fixedly connected to the top of the condensation chamber, further comprising:

[0006] A coolant assembly, the coolant assembly including a first connecting plate threaded to the outer surface of a condenser, the inner wall of the first connecting plate being fixedly connected to a circulation pipe via a connecting seat;

[0007] The purification component includes a collection hopper fixedly connected to the inner wall of the condensation box, and an installation groove is provided on the outer surface of the condensation box, with a second filter screen installed inside the installation groove.

[0008] As a further improvement to the above solution, a first filter screen is fixedly connected to the top of the inner wall of the condenser box, and a fan fixedly connected to the top of the first filter screen is provided on the top of the condenser box.

[0009] Through the above technical solution, the first filter screen intercepts large particulate impurities in the exhaust gas, preventing impurities from directly entering the cooling chamber. At the same time, through the flow equalization effect of the mesh, the exhaust gas is evenly distributed, reducing uneven heat exchange caused by local airflow concentration.

[0010] As a further improvement to the above scheme, the spray pipe is located inside the cooling chamber, and the liquid inlet pipe is located inside the sedimentation chamber.

[0011] With the above technical solution, the spray pipe is located directly in the cooling chamber, and the coolant does not need to be transported over long distances, which reduces heat loss in the pipeline. At the same time, the atomized spray can quickly cover the exhaust gas flow path and improve heat exchange efficiency.

[0012] As a further improvement to the above solution, a refrigerant inlet is fixedly connected to one side of the outer surface of the circulation pipe, and a refrigerant outlet is fixedly connected to the other side of the outer surface of the circulation pipe.

[0013] Through the above technical solutions, the counter-current design keeps the temperature gradient between the refrigerant and the exhaust gas at a high level, improves the driving force of heat transfer, and avoids the problem of decreased heat exchange efficiency in the later stages of the co-current design.

[0014] As a further improvement to the above solution, a partition is fixedly connected to the bottom of the collection hopper, and a second connecting plate is slidably installed inside the mounting groove.

[0015] Through the above technical solution, the guiding effect of the collection bucket ensures that all the condensate flows into the sedimentation chamber, thus avoiding waste of water resources.

[0016] As a further improvement to the above solution, the second connecting plate has ventilation holes inside, and an operating handle is fixedly connected to the outer surface of the second connecting plate.

[0017] As a further improvement to the above solution, a second filter screen is fixedly connected to the inner wall of the second connecting plate, and the second filter screen is disposed at the bottom of the partition.

[0018] Through the above technical solution, the second filter screen and the first filter screen form a stepped filtration, which further intercepts suspended particles in the condensate and prevents impurities from entering the cooling system.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] This invention uses a circulating water pump to pump coolant from the sedimentation chamber to the spray pipe. The coolant is atomized and sprayed into tiny droplets, which evenly cover the inner wall of the cooling chamber. At the same time, refrigerant enters the circulation pipe from the refrigerant inlet and flows counter-currently along the pipe wall under the support of the connecting seat, forming a reverse heat exchange path with the exhaust gas. The fan forcibly draws in the exhaust gas, allowing it to fully contact the coolant in the cooling chamber, accelerating heat exchange. The atomized spray increases the contact area between the coolant and the exhaust gas, and the counter-current design extends the heat exchange time between the refrigerant and the exhaust gas. The synergistic effect of both makes the heat exchange efficiency much higher than that of traditional co-current or unidirectional heat exchange modes.

[0021] This invention utilizes the principle that water droplets condensed in the cooling chamber fall into the sedimentation chamber under gravity. The collection hopper, fixed to the inner wall of the condenser, guides the condensate to the bottom of the sedimentation chamber. Simultaneously, the second connecting plate in the mounting slot can be slidably adjusted via an operating handle. A second filter screen fixed to its outer surface intercepts suspended particles in the water, while internal vents allow gas to pass through. The filtered condensate is diverted by a partition and returns to the sedimentation chamber, forming a closed-loop water circulation. The second filter screen intercepts suspended particles in the water, preventing impurities from entering the cooling system and reducing the risk of pipe blockage. Attached Figure Description

Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0030] Example:

[0031] Please combine Figure 1-5This embodiment of a high-efficiency counter-current microchannel condenser includes a condensation assembly 1, which includes a condensation chamber 101. The outer surface of the condensation chamber 101 has an exhaust gas inlet. The interior of the condensation chamber 101 has a sedimentation chamber 102 and a cooling chamber 103. A circulating water pump 105 is fixedly connected to the outer surface of the condensation chamber 101. An inlet pipe 104 is fixedly connected to the input end of the circulating water pump 105, and a delivery pipe 106 is fixedly connected to the output end of the circulating water pump 105. A spray pipe 107 is fixedly connected to the bottom of the delivery pipe 106. A fan 109 is fixedly connected to the top of the condensation chamber 101. The condenser also includes:

[0032] Coolant assembly 2 includes a first connecting plate 201 threadedly connected to the outer surface of condenser 101, and a circulation pipe 204 fixedly connected to the inner wall of the first connecting plate 201 via a connecting seat 202.

[0033] Purification component 3 includes a collection hopper 301 fixedly connected to the inner wall of condenser box 101. An installation groove 303 is provided on the outer surface of condenser box 101, and a second filter screen 306 is provided inside the installation groove 303.

[0034] A first filter screen 108 is fixedly connected to the top of the inner wall of the condenser box 101, and a fan 109 is fixedly connected to the top of the first filter screen 108.

[0035] The spray pipe 107 is located inside the cooling chamber 103, and the liquid inlet pipe 104 is located inside the sedimentation chamber 102.

[0036] The circulating water pump 105 pumps coolant from the sedimentation chamber 102 to the delivery pipe 106 through the inlet pipe 104, and then sprays it into the cooling chamber 103 in an atomized form through the spray pipe 107.

[0037] A refrigerant inlet 203 is fixedly connected to one side of the outer surface of the circulation pipe 204, and a refrigerant outlet 205 is fixedly connected to the other side of the outer surface of the circulation pipe 204.

[0038] A partition plate 302 is fixedly connected to the bottom of the collecting hopper 301, and a second connecting plate 304 is slidably installed inside the mounting groove 303.

[0039] The second connecting plate 304 has a vent 305 inside, and an operating handle 307 is fixedly connected to the outer surface of the second connecting plate 304.

[0040] The inner wall of the second connecting plate 304 is fixedly connected to a second filter screen 306, which is located at the bottom of the partition plate 302.

[0041] The second connecting plate 304 inside the mounting slot 303 can be slidably adjusted in position by operating the handle 307. The vent 305 inside allows gas to pass through, while the second filter screen 306 fixed on the outer surface intercepts suspended particles in the water. After the condensate is filtered by the second filter screen 306, it returns to the sedimentation chamber 102 through the diversion effect of the partition 302, forming a closed-loop water circulation.

[0042] The implementation principle of a high-efficiency counter-flow microchannel condenser in this embodiment is as follows: A circulating water pump 105 draws coolant from the sedimentation chamber 102 to the delivery pipe 106 through the inlet pipe 104, and then sprays it into the cooling chamber 103 in an atomized form through the spray pipe 107. Simultaneously, refrigerant enters the circulation pipe 204 from the refrigerant inlet 203, flows along the circulation pipe 204 under the support of the connecting seat 202, absorbs the heat from the exhaust gas in the cooling chamber 103, and then exits from the refrigerant outlet 205. The exhaust gas is drawn in by the fan 109 through the first filter 108 at the top of the condenser 101, causing it to come into countercurrent contact with the coolant in the cooling chamber 103, accelerating heat exchange. The atomizing spray of the spray pipe 107 and the refrigerant countercurrent design of the circulation pipe 204 significantly improve the gas-liquid contact area and heat exchange efficiency. At the same time, the forced convection of the fan 109 ensures that the heat in the exhaust gas is fully recovered, avoiding the problem of local overheating caused by uneven airflow distribution in traditional condensers.

[0043] During the cooling process, water vapor in the exhaust gas condenses into water droplets in the cooling chamber 103 and falls into the sedimentation chamber 102 under gravity. The collection hopper 301 is fixed to the inner wall of the condensation box 101, and its bottom is connected to the sedimentation chamber 102 to guide the condensate into the sedimentation chamber 102. At the same time, the second connecting plate 304 in the mounting groove 303 can be slidably adjusted in position by operating the handle 307. The vent 305 inside allows gas to pass through, while the second filter screen 306 fixed on the outer surface intercepts suspended particles in the water. After the condensate is filtered by the second filter screen 306, it returns to the sedimentation chamber 102 through the diversion effect of the baffle 302, forming a closed-loop water circulation. Through the guidance of the collection hopper 301 and the interception of the second filter screen 306, the condensate is efficiently recovered to the sedimentation chamber 102, while avoiding impurities from entering the cooling system with the water flow. The diversion design of the baffle 302 further optimizes the water flow path, reduces the risk of scale deposition, and improves the long-term operational stability of the system.

[0044] When the second filter screen 306 needs to be cleaned or replaced, the operator can pull the second connecting plate 304 through the operating handle 307, causing it to slide outward along the mounting groove 303, exposing the filtration area below the partition 302. After cleaning, the second connecting plate 304 is pushed back to its original position to restore the filtration function. The sliding design of the second connecting plate 304 and the user-friendly operation of the operating handle 307 simplify the filter screen maintenance process and reduce downtime. At the same time, the adjustable design of the vent 305 allows for flexible adjustment of the filtration intensity according to the exhaust gas flow rate or particle concentration, avoiding the problem of increased energy consumption due to excessive filtration resistance.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
