Embodiment

[0025] Taking one of the 150MW CCPP units of Maanshan Iron and Steel as an example, according to figure 1 In the existing process shown, the production of EP wastewater is about 20 to 25 tons / hour, and the annual treatment cost is nearly 10 million yuan; adopting the above-mentioned process of the present invention, after the system transformation, the production of phenol cyanide wastewater in CCPP unit is greatly improved. The reduction is only about 5 tons per hour, which can save about 7 million yuan in the annual treatment cost of EP wastewater, which greatly reduces the production and operation expenses; at the same time, due to the The role of the agent can effectively slow down the corrosion and scaling of the gas cooling water.

Abstract

The invention discloses a CCPP unit industrial gas dedusting water combined treatment process, relates to the technical field of gas-steam combined cycle generator set, and aims to solve the problem of high waste water treatment cost of gas-steam combined cycle generator set; the invention includes a gas cooler , EP dust collector, gas cooling water well, EP waste water pit, gas cooling water cooler, gas cooling water pump, EP waste water pump, EP circulating water pump, EP circulating water tank and high-efficiency clarifier tank, the water outlet of the gas cooler is connected to the gas cooling The water well and the EP circulating water tank, the water inlet of the EP circulating water pump is set at the lower part of the EP circulating water tank, the water outlet of the EP circulating water pump is connected to the water inlet of the EP dust collector, and the water outlet of the EP dust collector is connected to the high-efficiency clarifier. The two water outlets of the high-efficiency clarifier are respectively connected to the EP circulating water tank and the EP waste water pit; the invention can greatly reduce the waste water output, thereby reducing the cost of waste water treatment.

Description

technical field [0001] The invention relates to the technical field of gas-steam combined cycle power generation units, in particular to a combined treatment process for industrial gas dedusting and water for CCPP units. Background technique [0002] In order to realize efficient utilization of gas resources, gas-steam combined cycle power generation units (CCPP for short) are widely used in metallurgical enterprises. Its main technological process is as follows: after the industrial gas is dedusted by the gas electric precipitator, it enters the gas compressor for compression, and then enters the low-nitrogen combustion chamber for combustion. Steam turbines generate electricity. [0003] figure 1 It is a schematic diagram of the process flow of the existing gas cooling and dust removal system, in which the cooling water used for the gas cooler is directly cooled and then returned to the gas cooling water pit, pressurized by the pump to the plate heat exchanger for coolin...
