Abstract

The embodiment of the invention discloses a chemical plant water circulation control method and equipment, and the method comprises the steps that: controlling a circulating oil pump to operate based on the temperature of a solar heat collector, so that heat conduction oil circularly flows between the solar heat collector and a heat exchanger, and water in a steam generator is heated through the heat exchanger to generate steam; steam in the steam generator is conveyed to a workshop section needing to use the steam through a steam pipeline; the used steam is collected and condensed through a condenser, and condensate water in the condenser is conveyed into a cooling tower; based on the temperature in the cooling tower, a first water pump is controlled to operate, so that cooling water in the cooling tower is conveyed into industrial equipment needing water; wastewater generated by the industrial equipment needing water is collected into the wastewater treatment device through a pipeline to be treated; and the treated wastewater is conveyed into the steam generator through the second water pump. The technical problems that an existing chemical plant water circulation system wastes energy and is single in control mode are solved.

Description

technical field [0001] The present application relates to the field of automatic control, in particular to a method and equipment for controlling water circulation in a chemical plant. Background technique [0002] There are a large number of water-using equipment and heat-consuming sections in chemical plants, so the demand for water resources and heat energy in chemical plants is very high. In particular, superheated steam is widely used in the production of chemical plant workshops. The production of desulfurization section, ammonium sulfate section and other sections, as well as the heating of each section have a great demand for superheated steam. In order to save water resources, each chemical plant has its own water circulation system to recycle waste water. [0003] In the actual production process, steam boilers generally use natural gas, fuel oil, and electric heating to provide heat, but these energy sources are high in cost and have certain pollution to the envi...
