Abstract

The embodiments of the present application disclose a method and equipment for controlling water circulation in a chemical plant. The method includes: controlling the operation of a circulating oil pump based on the temperature of the solar heat collector, so that the heat transfer oil circulates between the solar heat collector and the heat exchanger. , to heat the water in the steam generator to generate steam through the heat exchanger; transport the steam in the steam generator to the section that needs to use steam through the steam pipeline; collect the used steam through the condenser and condense, and The condensed water in the condenser is sent to the cooling tower; based on the temperature in the cooling tower, the operation of the first water pump is controlled to send the cooling water in the cooling tower to the industrial equipment that needs water; The waste water produced by the industrial equipment is collected in the waste water treatment device for treatment; the treated waste water is transported into the steam generator through the second water pump. It is used to solve the technical problems that the existing chemical plant water circulation system wastes energy and has a single control mode.

Description

technical field [0001] The present application relates to the field of automatic control, and in particular, to a method and device for controlling water circulation in a chemical plant. Background technique [0002] There are a large number of water equipment and heat-using sections in chemical plants, so chemical plants have very high demand for water resources and thermal energy. 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 and the heating of each section have great demand for superheated steam. To conserve water resources, each chemical plant has its own water recycling system for recycling wastewater. [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 costly and pollute the environment to a certain extent. After the superheat...
