Description

Technical Field

[0001] The utility model relates to the technical field of condensers, in particular to an energy-saving countercurrent evaporative condenser. Background Art

[0002] The countercurrent evaporative condenser is the main heat exchange equipment in the refrigeration system. Its working principle is: the superheated high-pressure refrigerant gas discharged from the compressor in the refrigeration system passes through the condensation exhaust pipe in the evaporative condenser, so that the high-temperature gaseous refrigerant exchanges heat with the spray water and air outside the exhaust pipe, that is, the gaseous refrigerant enters the exhaust pipe from the top and is gradually condensed into liquid refrigerant from top to bottom.

[0003] However, when the existing countercurrent evaporative condenser is in use, the spray water continuously exchanges heat with the air. At the same time, when the spray water drips onto the condenser, the condenser is exposed to the air. Therefore, the spray water will bring the air and dust on the condenser into the water tank. If the water is not treated in time, the spray water will carry impurities, which will affect the heat exchange efficiency and easily cause blockage in the pipeline. Therefore, we propose an energy-saving countercurrent evaporative condenser. Utility Model Content

When the existing countercurrent evaporative condenser is in use, since the spray water continuously exchanges heat with the air, and when the spray water drips onto the condenser tube, the condenser tube is exposed to the air, the spray water will bring the air and dust on the condenser tube into the water tank. If the water is not treated in time, the spray water will carry impurities, which will affect the heat exchange efficiency and easily cause blockage in the pipeline.

[0010] As a preferred solution of the utility model, the detachable dust removal assembly includes a middle section pipe, and both sides of the two middle section pipes are connected to fixed pipes.

[0011] The technical effect of adopting the above further solution is that the middle section pipe can be disassembled, thereby facilitating disassembly between the two fixed pipes, and facilitating replacement or cleaning of the filter element inside the middle section pipe.

[0012] As a preferred solution of the utility model, connecting flanges are fixedly connected to the inner sides of the two fixed pipes and the two side walls of the middle pipe, and the middle pipe and the fixed pipe are connected and fixed by bolts of the connecting flanges.

[0013] The technical effect of adopting the above further solution is that when replacing, it is only necessary to remove the bolts at the middle section pipe and the fixed pipe, and the rear middle section pipe can be removed as a whole.

[0014] As a preferred solution of the utility model, a limiting plate is further provided inside the middle section tube, and a filter element is provided on the limiting plate and inside the middle section tube.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] In the utility model, when spraying water, water will reach the detachable dust removal component from the water tank, the detachable dust removal component will filter the water inside the pipe, and then the filtered water will be pressurized for a second time by a pressure pump and sent to the spray system. At the same time, the detachable dust removal component adopts a detachable structure, so that the internal filter element can be replaced and cleaned, avoiding the problem that some countercurrent evaporative condensers are constantly exchanging heat with the air when in use, and the condenser is exposed to the air when the spray water drips onto the condenser. Therefore, the spray water will bring the air and the dust on the condenser into the water tank. If the water is not treated in time, the spray water will carry impurities, which will affect the heat exchange efficiency and easily cause blockage in the pipe. BRIEF DESCRIPTION OF THE DRAWINGS
