Description

Technical Field

[0001] The utility model relates to the technical field of molten salt heat storage tanks, in particular to a molten salt heat storage tank. Background Art

[0002] As is known to all, the molten salt heat storage tank is a scientific instrument used in the field of energy science and technology, which has the characteristics of high temperature, high pressure and corrosion resistance. When the molten salt heat storage tank in the prior art is preheated, the preheated air cannot completely reach the bottom, and the cold air is deposited at the bottom of the tank body, resulting in the bottom of the tank body being unable to be preheated effectively in time, thereby causing uneven heating in the tank, resulting in local overheating in the tank. In order to solve this problem, the China Patent Network discloses a molten salt heat storage tank with a publication number of CN219757083U, including a heat storage tank body, wherein a preheating gas pipe is arranged inside the heat storage tank body, and a serpentine pipe is fixedly connected to one side of the preheating gas pipe. The jet assembly includes an air outlet seat, an air guide pipe, an exhaust through-hole and a sealing cover plate; the preheating air supply pipe and the serpentine pipe cooperate to achieve uniform preheating of the bottom of the heat storage tank body, and the preheating air supply pipe and the air outlet seat cooperate with each other to achieve synchronous jetting at different positions inside the heat storage tank body to improve the uniformity of jet preheating, and the air guide pipe and the exhaust through-hole cooperate so that the air guide pipe is in an open state during exhaust to ensure the exhaust effect, and when not exhausting, the air guide pipe is reset with the cooperation of an external spring, and the sealing cover plate cooperates with the air outlet seat to achieve shielding and blocking of the air guide pipe and the air outlet seat to prevent molten salt from entering the inside of the air outlet seat during preheating without exhaust, thereby ensuring the stability of gas supply through the preheating air supply pipe.

[0003] However, although the molten salt heat storage tank in the prior art makes the heating inside the tank more uniform and solves the problem of local overheating in the tank during preheating, since the air outlet seat is directly fixed to the preheating gas pipe and the spring inside the air outlet seat for controlling the sealing cover plate is arranged inside, it causes inconvenience when the spring needs to be replaced due to deformation after long-term telescopic use, which is not conducive to the stable use of the preheating system in the tank. For this reason, we propose a molten salt heat storage tank. Utility Model Content
