Problems solved by technology

Traditional cooling towers are mostly used to cool water or steam at higher temperatures, and adopt forced circulation and add spraying devices. The equipment is complex and expensive
For water with a cooling temperature of about 100°C (such as atmospheric reactors, industrial boilers, etc.), the conventional cooling tower design will not be able to meet the requirements of practical industrial applications.
The reasons are mainly manifested in two aspects: First, the heat transfer tubes of conventional air cooling towers are mostly arranged at the bottom of the tower body, and the air side circulation power is to increase the wind speed through power equipment such as fans, and increase the air humidity through spraying to enhance heat transfer , the water side circulation can only provide the dynamic pressure head through the pump. The disadvantage of this design structure is that it not only increases the equipment and thus increases the cost, but also cannot meet the passive characteristic requirements required by the atmospheric pressure reactor; the second is that for normal temperature and pressure As far as the stack is concerned, due to the low temperature of the water, the traditional cooling tower design structure will cause the heat transfer area in the cooling tower to be too large and the volume of the cooling tower will be too large, resulting in high cost and unable to meet the cost requirements of commercial operation

Embodiment Construction

[0014] Such as figure 1 As shown, a full natural circulation air cooling tower includes a tower body and a rising pipe 3 connected to the heat pipe section 10 of the atmospheric pressure reactor secondary circuit arranged in the tower body. The rising pipe 3 is vertically arranged, and the outer side is covered with an insulating layer 9, the thermal insulation layer 9 generally can use thermal insulation cotton. An expansion tank 2 is provided at the top of the riser pipe 3, and the expansion tank 2 is connected to a vertically arranged heat transfer tube 4. The main function of the expansion tank 2 is to distribute water to the heat transfer tube 4 more evenly. In addition, there is a space for nitrogen pressure stabilization on the upper part of the expansion tank 2 to ensure that the pressure of the secondary circuit exceeds the pressure of the primary circuit under any working conditions. According to specific requirements, the pressure can be adjusted by charging and di...

Abstract

Present invention relates to a heat exchanging apparatus, especially an all natural circulation atmospheric cooling tower used for normal pressure nuclear heat supply pile. Said all natural circulation atmospheric cooling tower includes tower body, heat transfer pipe, chimney, normal pressure pile secondary loop heat tube, rising pipe, expansion box, water tank, thermal insulation blanket and fins. Said structure characteristics effectively enlarge waterside natural circulation ability and air side reasonable natural circulation ability for ensuring transferring heat quantity to atmosphere for long time.

Description

technical field [0001] The invention relates to a heat exchange device, in particular to a full natural circulation air cooling tower used in an atmospheric pressure nuclear heat supply reactor. Background technique [0002] With the rapid development of the world economy, the lack of water resources has caused widespread concern in the world, and it is an advisable way to use the inexhaustible seawater resources as a supplement to human water resources for survival. For this reason, countries all over the world have begun to use nuclear energy for seawater desalination research and exploration for many years, but it has not yet been widely used commercially. It is safe to pay high construction and operation costs and expensive seawater desalination facilities using special materials, so that the price of freshwater production cannot compete with the market, which restricts its development. At present, a certain-scale low-temperature multi-effect distillation seawater desal...
