Description

Evaporative condenser and detachable maintenance type box plate thereof

Technical Field

The utility model relates to the field of heat exchangers, in particular to an evaporative condenser and a detachable maintenance type box plate thereof.

Background

The evaporative condenser is a main heat exchange device in a refrigeration system, and structurally comprises an evaporation coil part, a lower box part, an air system part and a water system part. The working process is as follows: high-temperature and high-pressure medium gas enters the condensing coil, cooling water is pumped into the spraying device above the evaporating coil by the circulating water pump, and then is uniformly sprayed on the surface of the condensing coil by the nozzle to form a water film, the medium in the coil exchanges heat with water and air outside the coil, and the cooling water outside the coil evaporates and absorbs heat released by the medium in the coil through condensation. The axial flow fan forces air to pass through the condensing coil pipe, and the damp and hot air is discharged out of the equipment in time. The moisture contained in the hot and humid air is trapped and separated in a dehydrator. The cooling water which is not evaporated falls into the water tank, and is continuously circulated by the circulating water pump, and the water lost by evaporation is automatically supplied by the ball float valve.

In the long-term operation process of the spray water system of the evaporative condenser, external dust and impurities enter the evaporative condenser and gradually accumulate on the heat exchange coil and the water collector to form a scale layer, and the heat exchange thermal resistance is increased. The shower nozzle is easily blocked after the spray water enters the sundries, so that the spray water is unevenly sprayed, and dry spots appear on the heat exchange coil. The factors greatly influence the heat exchange capability of the equipment, so that the equipment fails in advance; the evaporative condenser requires periodic cleaning of its interior. However, in order to prevent the cooling water from leaking during the use of the evaporative condenser, the sealing performance of the box body needs to be ensured, so that the box body of the existing evaporative condenser needs to be sealed, and the above-mentioned periodic cleaning requirement cannot be met.
