Embodiment

[0025] The present invention adopts following optimization mode:

[0026] Step 1: After determining the treatment process of "ultrafiltration + reverse osmosis + first-stage desalination + mixed bed" according to the optimization calculation of boiler feed water, the interval between using "ion exchange" units as backup is an average of 15 for each bed type. With the feature of once-a-day regeneration, there is no need to set up emergency plan equipment; Huashui main building is equipped with ultrafiltration reverse osmosis and ion exchange equipment across the water treatment workshop. The channel drains directly to the waste water storage tank.

[0027] The second step: cancel the reverse osmosis water tank and the reuse water pump in the circulating water sewage desalination system, and directly discharge it to the hydraulic reuse water pool through the pipeline.

[0028] The third step: cancel the clean water tank and clean water pump in the industrial wastewater treatmen...

Abstract

Provided is an intensive layout structure of a large-scale thermal power plant water center. The large-scale thermal power plant water center includes a joint building, an outdoor structure and a wastewater treating area; a ground floor of the joint building includes a water treating workshop, a comprehensive pump house, a laboratory building, a pump compartment, a power distribution room, a control room, a fire-pump room and a dosing room, wherein a second floor is arranged above the comprehensive pump room and the laboratory building, and all laboratories, experimenter offices, a storage room, a lime powder bin and a dehydrator room are arranged on the second floor; the outdoor structure includes water tanks at all levels, desalting water tanks and various pools; a wastewater treating pool of the wastewater treating area is arranged beside the outdoor structure, the top of the wastewater treating pool is provided with a wastewater pump, and a series of wastewater treating devices arearranged beside the wastewater treating pool; the joint building is an L-shaped building composed of a horizontally arranged main building and an annex building which is vertically connected with themain building, wherein the ground floor of the main building mainly includes the laboratory building and the comprehensive pump room, and the annex building mainly includes the water treating workshop.

Description

technical field [0001] The present invention relates to an intensive layout structure of a large-scale thermal power plant water center, which is a layout structure that organically optimizes and integrates various related systems of power plant chemistry and hydraulic technology to achieve an intensive layout effect. Background technique [0002] At present, my country's central and eastern coastal areas are developing rapidly. In order to meet the requirements of economic development in this area and improvement of people's living standards, the country needs to invest huge sums of money in the construction of power plants. Land is a limited natural resource and a non-renewable scarce resource. Reasonable land use and land conservation are a basic national policy. Based on the support of advanced science and technology, considering the rationality and advancement of the process, the purpose of saving land through intensive layout is the focus of current power plant design....
