Dry-wet combined dual-cooling multi-condition cross-flow closed cooling tower and regulating method for running mode of cooling tower

Abstract

The invention provides a dry-wet combined dual-cooling multi-condition cross-flow closed cooling tower and a regulating method for the running mode of the cooling tower, and belongs to the technical field of cooling by circulating water. The cooling tower comprises a tower body, draught fans, water absorbers, a finned tube bundle heat exchanger, a plain tube bundle heat exchanger, a water spraying system, air inlets, a filler, a water collecting tank, a make-up floating ball valve and a drain valve, wherein the inner cavity of the tower body is divided by the water absorbers into two parts: a left cavity and a right cavity; the draught fans are mounted at the top of the left cavity; a first spraying row tube, the finned tube bundle heat exchanger, a second spraying row tube, a plain tube bundle heat exchanger, the filler and the water collecting tank are arranged in the right cavity from top to bottom; and the first air inlet, the second air inlet and the third air inlet are formed in the right wall of the right cavity from top to bottom. The cooling tower provided by the invention has the advantage that the dry-wet combined dual-cooling multi-condition flexible conversion can be achieved by regulating the number of the draught fans which need to start up, the air inlets, the water amount and the water spraying tow tubes according to changes in the outdoor environment and those in the heat dissipating capacity of cooling water, thereby fulfilling the energy-saving, water-saving and efficient cooling purposes.

Description

technical field [0001] The invention belongs to the technical field of circulating water cooling, and relates to a dry-wet combined double cooling multi-working condition cross-flow closed cooling tower and an adjustment method for its operation mode, in particular to a dry-wet cooling tower adopting air cooling and evaporative cooling. Combined dual cooling and multi-working condition cross-flow closed cooling tower and its operation mode adjustment method. Background technique [0002] As a new type of circulating water cooling and heat dissipation equipment, the cross-flow closed cooling tower has been widely used in more and more fields because of its advantages of high efficiency, energy saving, water saving, and water quality that is not easily polluted. In the existing cross-flow closed cooling tower, the water flow is sprayed vertically downward from the upper part of the tower body, and the air horizontally sweeps the heat exchange tube bundle and the water spray fi...
