Description

Comprehensive utilization device for preparing pure condensate water and treating water resources in thermal power plant

Technical Field

The invention relates to a pure condensed water preparation device, in particular to a comprehensive utilization device for preparing pure condensed water and treating water resources in a thermal power plant.

Background

Water is a source of all organic compounds and living matters and is a precious resource for human life. The world health organization indicates that: 80% of diseases of human beings are related to water pollution, and people can have no food for three days and can not have no water for one day. With the increasing industrial pollution, the discharge of domestic and industrial sewage, the secondary pollution of water delivery networks and pressurizing equipment, the speed of water pollution treatment is far from the speed of water pollution, the water works add alum, bleaching powder and chlorine gas for water purification to sterilize, and the sterilization medicines become new water pollution sources. The prior production process of bottled pure drinking water is basically prepared by ozone sterilization after membrane filtration. In the method, if the bromide background content in the raw water is higher, the risk of generating bromate is increased, and the bromate is a byproduct generated after a natural water source is disinfected by ozone. The pollutants contained in the mineral water due to rainfall are filtered by the soil for a long time, so that the natural filter layer is saturated, harmful substances exist in the mineral water, and the quality of the natural mineral water is reduced.

It has been shown that healthier drinking water is boiled water. In the field of traditional Chinese medicine, a miraculous prescription, namely Taihe soup, is recorded in Li Shizhen Ben Cao gang mu, namely cold boiled water, can 'help yang qi and move meridians and collaterals', and the traditional Chinese medicine teaches that cold is a source of all diseases, so that cold boiled water is better than raw water. Japanese researches also find that the cold boiled water has the effects of promoting blood circulation, promoting in-vivo purification, edema and constipation, improving skin and the like.

Modern scientific research shows that water is heated and then changed from a large molecular group into a small molecular group, which is beneficial to water passing through cells and accelerating metabolism of human bodies.

Due to the health characteristics of boiled water, the production research of boiled water in the prior art is related, for example, Chinese patent 201510910166.1 adopts a 1500-2500 MHz microwave heating mode to realize the production of 'boiled water' purified water, but the mode has high energy consumption and is not suitable for mass production in factories.

For example, chinese patent CN106186490B, a cold boiled water production process, needs UHT heat sterilization, and introduces degassed clean water into UHT sterilizer for heat sterilization, and because raw water needs to be softened, high salt water must be discharged from natural water, which not only wastes water resources, but also causes pollution of high salt water in river and natural water.

Nowadays, with environmental pollution, it is difficult to introduce a clean and pollution-free water, so that various water layers using water sources as selling points are endless. However, the disposal cost and the transportation cost thereof cause great waste to the country and great economic burden to the consumers. Some water even makes fake and can not reach the safety index for drinking water. This is a common occurrence. Therefore, the unified standard of water is realized, and the materials are obtained nearby.

In a thermal power plant system, a boiler changes water into saturated steam and superheated steam to drive a steam turbine to do work and finally condense the steam into water, and the necessary process is to obtain high-energy small-molecular water, and the process is operated well, so that the disinfection and sterilization effects of the boiler can be fully exerted, no extra energy is consumed, and the existing water treatment is to do energy which must be consumed in a plurality of technological processes for pursuing water quality, and waste unnecessary waste water, so the existing process is eliminated.

The evaporation capacity of a boiler in a power plant is up to hundreds to thousands of tons per hour, however, more than 90-95% of condensed water is recycled by the boiler. In the existing boiler water of a power plant, because the chemical is added, for example, the boiler water needs to be added with ammonia, trisodium phosphate needs to be added, and the oxygen removal needs to be added with hydrazine, which is toxic. Therefore, people have a lot of prejudices on the condensate water of the condenser, but the physicochemical indexes of the condensate water are not understood, and the condensate water of the power plant can not be drunk. Therefore, people still spend high price on producing purified water, mineral water, distilled water and pure condensed water. The method consumes a large amount of energy and wastes a large amount of water resources. When people abandon the prejudice, people will burst after drinking water revolution. The method is an economic and convenient way for developing drinking distilled water by utilizing condensed water of a power plant, only a plurality of further purifying devices and sterile filling workshops need to be added, and the social benefit and the economic benefit are better.

According to stage 3 of "Jiangsu food and fermentation" 1996: the process flow of the paper published by the discussion (author: Nippon) of producing drinking distilled water by using condensed water of a power plant is as follows:

condensed water inspection → mixed bed treatment → fine filtration → sterilization → ultrafiltration → secondary sterilization → filling → capping → lamp inspection → labeling → boxing and warehousing

The process has a problem that when the condensed water is used as drinking distilled water, the condensed water containing ammonia which is originally circulated is used in a large amount without participating in the circulation. Condensate water which originally accounts for 90-95% of boiler water replenishing is intercepted, and the lacking boiler water replenishing is replenished by chemical water treatment, so that the wastewater with extremely high salt content generated by the chemical water treatment is greatly increased. The amount of ammonia contained in the boiler feed water is considerable, which causes a great operating pressure on the mixed bed. When the mixed bed is used for treating water, a large amount of waste acid and waste alkali are discharged, and the displaced ammonia is a nutrient-rich component. Because of the huge amount of wastewater with high salt content and ammonia content, the natural water body can be seriously polluted by rich nutrition and high salt content water, and the recyclable ammonia is wasted. Meanwhile, because a condensed water heat recovery system is not arranged, the energy is greatly wasted, and the energy is not economical. And a large amount of ammonia is discharged into wastewater of chemical water treatment, so that the wastewater discharged by the chemical water treatment is highly eutrophic and has high salt content, and serious eutrophication and high salt-containing pollution can be caused to natural water. This is the root cause of the technology which has been born but has not been successfully popularized yet.

In a thermal power plant system, water is changed into steam, the steam is changed into superheated steam to push a steam turbine to do work, the superheated steam is finally condensed into water, and the necessary process is obtained, and the process is well operated, so that the sterilization and disinfection effects of a boiler can be fully exerted, and no extra energy is consumed. Therefore, how to solve the problem of recycling ammonia in the condensed water and how to solve the problem of zero emission of the high-salinity wastewater of the power plant is the core technical problem of preparing pure drinking condensed water by using the condensed water.

The condensed water is purified by a physical method, and the purified small molecule drinking condensed water can be obtained by further purifying the condensed water, and can be sold after being directly packaged. And the clean functional water can be obtained by filling ozone for sterilization and disinfection. The mineral water with directional nutrient elements can be obtained by carrying out mineralization treatment on the mineral water, the mineral water with directional nutrient elements can be obtained by carrying out mineralization and oxygenation treatment on the mineral water, pure drinking condensed water with a certain degree of mineralization can be obtained, and direct supply of the mineral water can enable each family to obtain direct drinking water.
