The invention discloses a method for visualizing equipment information based on equipment map, which comprises the following steps: utilizing JAVA to compile a Web program capable of displaying, selecting or editing plant structure layout map, equipment layout map and equipment account information, and accessing the Web program through a browser; drawing the layout map of the factory building structure according to the scale and upload the layout map to the server; on the map of plant structure layout, the map of plant equipment layout being drawn in the map of plant structure layout and uploaded to the server according to the scale; associating equipment account information with plant structure layout maps and equipment layout maps. The invention has the advantages that: the method solvesthe problem that the dispersed equipment is difficult to manage, realizes the digitalization, visualization and centralization of the equipment management, can remotely monitor the running state of the equipment, and utilizes JAVA to compile the Web program, so that the method is low in cost, low in difficulty, convenient to access, and can implement the monitoring of the running state of the equipment.

The invention discloses an alkali preparing process for wetly decomposing and evaporating alkali halide containing NaHCO3, which comprises the following steps: adding purified brine in the refining process into a clear liquid storage tank; successively adding the brine into a first effective wet decomposition evaporator, a second effective wet decomposition evaporator, a third effective evaporator and a fourth effective crystallizer after the brine is sent to a primary preheater, a secondary preheater and a tertiary preheater in sequence by using a purified brine pump; and obtaining a crystal in the fourth effective crystallizer; and then sending the crystal to the filtering process. Primary steam used by the first effective wet decomposition evaporator adopts back pressure steam of 0.45MPa (absolute pressure); condensed water generated after being preheated by a primary clear liquid preheater is returned to a boiler; secondary steam generated by each effective evaporator is used asa next effective heat source; and secondary steam generated during the fourth effective evaporation process is emptied after passing through a surface condenser. By adopting the production technologyof the wet decomposition and evaporation process, the process flow of natural alkali preparing pure alkali is shortened, the production cost is reduced, the problem of environmental pollution in the traditional art is solved, and the production of the pollution-free natural alkali preparing pure alkali is achieved.
