Abstract: The steel structure water storage system is a common form in the water storage industry. The main body of the structure is the cold storage tank. According to the classification of the pressure-bearing form, it is divided into an open tank and a closed tank. Closed tanks are often included in the scope of pressure vessels, one of the major categories of special equipment. They have the characteristics of small volume and large pressure, and most of their volumes are concentrated in the range of 50-300 cubic meters. The closed cold storage tank is divided into vertical and horizontal from the installation method. Its applications are mainly concentrated in data center buildings and projects, and exist as emergency cold sources (redundant disasters). Shenzhen Taiwa Energy Technology Co., Ltd. also undertakes the production and construction of closed cold storage tanks and open cold storage tanks. This content focuses on the introduction of steel structure cold storage tanks and open steel structure water cold storage systems with steel structure cold storage tanks as the main body.

The scope of application of the cold storage tank water storage system:

The first choice, the application of water cooling system and engineering, is mainly concentrated in areas with peak-to-peak and valley electricity price differences, while the steel structure cooling tank water cooling system is mostly used in factories, industrial parks, and large public facilities with abundant land due to its own characteristics. Construction industries and regions such as airports. Due to the ample ground area of the main body of this type of building, it is easier to locate and construct the cold storage tank. For example, industrial parks, energy stations, Shenzhen Airport, Shanghai Hongqiao Airport, Chengdu Tianfu Airport and other large-scale power energy stations are currently in full swing.

The composition of the cold storage tank water storage system: (foundation, main structure, water distribution system, escalator, maintenance platform)

The water cold storage system of the cold storage tank structure mainly includes three parts: the power part of the computer room, the cold storage tank, and the control system. components), and the control system is the monitoring and control system of the entire HVAC energy storage system. The cold storage tank includes the basic platform of the cold storage tank, the main structure of the tank, the water distribution system, the escalator, and the maintenance platform.

The construction process of the cold storage tank:

Construction preparation → plate production and processing → foundation re-measurement and marking → bottom plate assembly welding → top ring wall plate assembly welding → tank roof assembly welding → lifting mast installation → top plate and tank roof overall lifting → the remaining circle wall plates are assembled one by one Welding and lifting → group welding of bottom ring wall plate and bottom plate edge plate → welding of bottom plate middle plate and edge plate → accessories installation → tank bottom sealing inspection → water filling settlement test → tank anti-corrosion treatment → tank body insulation and protection.

The construction focus of the cold storage tank process:

During the construction of the cold storage tank, it is necessary to grasp the connection and sequence between the processes, and to strengthen the management and inspection of the construction for the difficult and difficult parts. The construction of the cold storage tank mainly focuses on the following links. Prefabrication of energy storage tank, welding of tank bottom plate, welding of tank wall plate, lifting and flipping of mast in tank and setting of mast, welding of ring plate, water filling and settlement test of tank body, anti-corrosion and heat insulation, main line of water distribution system Installation, rust removal, corrosion protection and heat preservation of energy storage tanks. The diagram is as follows:

Acceptance of cold storage tank water storage system:

The acceptance of the cold storage tank water storage system is mainly for the acceptance of the power part of the machine room, the acceptance of the cold storage tank, and the acceptance of the control system. The acceptance of the cold storage tank is mainly to accept the performance and parameters of the tank body such as air tightness and flatness through vacuum inspection, non-destructive inspection of welds, water filling test, stability test and other methods. For the acceptance of cans, refer to the corresponding national regulations and standards (details are attached separately)
