Embodiment Construction
[0037] In the existing pickling system, a mixer is used to accelerate the dissolution of solid sulfamic acid, which increases the complexity of the pickling system, and also increases the production cost of the pickling system.
[0038] In view of this, the present invention provides a kind of pickling system, has reduced the stirrer that is used for accelerating the dissolving of solid sulfamic acid, utilizes acid adding pump as the power source that accelerates dissolving sulfamic acid, makes the flow out from the acid liquid preparation circulation pipe The pickling solution impacts and stirs the sulfamic acid solid to accelerate the dissolution of the sulfamic acid solid; thereby simplifying the structure of the pickling system and reducing the production cost of the pickling system.
[0039] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the embodiments of the present invention will be described in detail ...

The invention relates to the technical field of sea water desalinization, and in particular to a pickling system. The pickling system is used for simplifying the structure thereof and reducing the manufacture cost thereof. The invention discloses the pickling system, which comprises a pickling liquor box, an acid adding pump communicated with the pickling liquor box, an acid adding pipe with one end communicated with a liquid outlet of the acid adding pump, a pickling liquid feeding device communicated with the other end of the acid adding pipe and enabling the pickling liquid to enter a low-temperature multiple-effect sea water desalinization system, a pickling liquor preparation circulation pipe communicated with the liquid outlet of the acid adding pump, wherein one end of the pickling liquor preparation circulation pipe stretches into the pickling liquor box, an acid adding valve arranged on the acid adding pipe, and a pickling liquor preparation circulating valve arranged on the pickling liquor preparation circulating pipe. According to the invention, a stirrer is omitted; and the structure of the pickling system is simplified, so that the manufacture cost of the pickling system is reduced.
Description
technical field [0001] The invention relates to the technical field of seawater desalination, in particular to a pickling system. Background technique [0002] During the operation of the low-temperature multi-effect seawater desalination system, seawater evaporates and concentrates on the surface of the heat exchange tubes of each effect evaporator, which is prone to fouling, thereby reducing the heat exchange efficiency between seawater and steam; therefore, it is necessary to remove the Fouling on the surface of the heat exchange tubes. [0003] At present, the pickling system is generally used to inject pickling liquid into each effect evaporator in the low-temperature multi-effect seawater desalination system to remove the dirt on the surface of the heat exchange tube of the evaporator. Because the heat exchange tube material of the evaporator is mostly aluminum brass or aluminum alloy, in order to reduce the corrosion of the heat exchange tube of the evaporator by the...
