Abstract
The utility model relates to the technology field of a ventilation system of a containment vessel in a nuclear power station, and particularly discloses a four-side coil pipe type circulating cooling unit of the containment vessel to maintain the containment vessel at an atmospheric environment temperature. The circulating cooling unit comprises a casing, coil pipes and a fan, wherein the coil pipes are disposed in four vertical sides of the casing in counter flow, the casing is provided with the fan positioned at the lower reaches of the coil pipes, air cooled by the coil pipes is fed into an air duct by the fan and distributed by the air duct to each area of the containment vessel. The four-side coil pipe type circulating cooling unit of the containment vessel has the advantages that developed equipment parts are adopted to ensure the unit reliability as far as possible; and a four-side coil pipe type arrangement is adopted in the unit, air treatment capacity is large, effect is obvious, unit structure is compact, and occupation space is small.
Description
Technical field
The utility model belongs to nuclear power plant containment shell ventilating system technical field, is specifically related to a kind of four sides coil-type containment circulating cooling unit of keeping the containment atmospheric temperature.
Background technology
Containment plays preventing that radiomaterial is diffused into the effect in atmospheric environment as the isolation boundary of reactor and external environment.According to nuclear power station design experiences in the past, in containment, atmospheric temperature need be maintained within a certain range, and enters demand to satisfy equipment working temperature demand and personnel.
Due to generation amount of heats such as reactor core reactions, in containment, atmospheric temperature continues to raise, and needs the cooling mode of dependence mechanical ventilation to reduce atmospheric temperature in containment.Containment circulating cooling unit provides air after cooling processing for atmospheric environment in containment, and containment each zone is lowered the temperature, and guarantees that in containment, atmospheric temperature is in setting range.
Summary of the invention
The purpose of this utility model is to provide a kind of four sides coil-type containment circulating cooling unit, can provide air-treatment ability than Wind Volume with less taking up room, and improves cooling effect.
The technical solution of the utility model is as follows: a kind of four sides coil-type containment circulating cooling unit, this circulating cooling unit comprises casing, coil pipe and blower fan, wherein, casing along vertical axes to four faces in counter-flow arrangement coil pipe is arranged, be provided with blower fan on casing, be located at the downstream of coil pipe, make by the cooled air of coil pipe, send into airduct by blower fan, and be dispensed to containment each zone by airduct.
Described casing adopts hot-strip to make, and adopts channel-section steel, angle steel or square steel as the casing web frame.
Described cabinet panel adopts the combustion-proof glass fiber heat-insulation layer to carry out insulation.
Described casing has the hinge sealing manhole of sufficient size in place.
Described coil pipe is the fin tube type of chuck mode, and its at right angle setting can connect from casing the opposite side dismounting of side in casing.
Described blower fan is the double speed axial flow blower, and Blower Housing adopts heavy carbon steel to make, and fan blade adopts die casting to make, and material is stainless steel, and the fan blade angle adjustable.
Remarkable result of the present utility model is: a kind of four sides described in the utility model coil-type containment circulating cooling unit adopts ripe part of appliance, to guarantee as far as possible unit reliability; Simultaneously, this unit adopts the four sides coil-type to arrange, the air-treatment amount is large, successful, and set structure is compact, takes up room little.
Description of drawings
