Compensation positive pressure drying system

Abstract

The invention discloses a compensation positive pressure drying system comprising an air circulating system, a water discharging system and a control system. The air circulating system comprises a compensation dehumidifying host and an air distribution pipeline, wherein the compensation dehumidifying host consists of a first-grade dehumidifying machine, a second-grade dehumidifying machine, a dehumidifying machine air inlet and a dehumidifying air outlet; the air distribution pipeline is formed by an air inlet pipe and an air outlet pipe; and the air inlet pipe is formed by an air inlet main pipe, an air inlet mother pipe and a plurality of sets of air inlet branch pipes. The water discharging system comprises a first-grade water receiving tank, a second-grade water receiving tank, a first-grade water discharging pipe, a seconded-grade water discharging pipe and a water storage tank. The control system is formed by a first-grade humidity sensor and a second-grade humidity sensor. The compensation positive pressure drying system is simply structured and convenient to use; no other changes are conducted to a dehumidifying target expect for the air through holes and the circulating pipelines; second-grade dehumidifying through dry air can be conducted to the dehumidifying target via positive pressure, so humid air can be discharged; and condensation in the dehumidifying target can be dried, so purposes of dehumidifying and condensation elimination can be achieved.

Description

Technical field [0001] The invention relates to a drying system, in particular to a compensation type positive pressure drying system. Background technique [0002] At this stage, there are many methods for dehumidification of switch cabinets. There are dehumidifiers installed in the high-pressure room, the traditional heating and dehumidification in the cabinet, and the semiconductor dehumidifier, but the effect is not obvious, because it simply depends on the external environment of the high-pressure cabinet. Installing dehumidification equipment in the high-voltage room, or placing a heater in the switch room, or using special thermoelectric semiconductor materials according to the Peltier effect, manufacturing semiconductor refrigeration devices for dehumidification, can’t effectively prevent the moisture in the high-voltage cabinet from passing over and forming condensation. dew. To solve the problem of excessive humidity and condensation in the switch cabinet, the problem ...

[0002] At present, there are many ways to dehumidify the switchgear. There are dehumidifiers installed in the high-voltage chamber, traditional heating and dehumidification in the cabinet, and semiconductor dehumidifiers, but the effect is not obvious, because simply relying on the external environment of the high-voltage cabinet is enough. Installing dehumidification equipment in the high-voltage chamber, or placing a heater in the switch chamber, or using special thermoelectric semiconductor materials to manufacture semiconductor refrigeration devices for dehumidification according to the Peltier effect cannot effectively prevent the moisture in the high-voltage cabinet from passing through and form condensation. dew
