Problems solved by technology

[0005] In an open system, because the internal circulation of the pipe network is in direct contact with the atmosphere, the water supply pressure of the water supply pump will drop to zero relative to the atmospheric pressure when it enters the return pipe and the pool, resulting in waste of energy for the water supply pump in the circulation operation; a large amount of water At the same time as evaporation, the concentration of salt in the circulating water increases, and the pollutants in the atmosphere enter the circulating water system, and the water quality in the pipe network is polluted; when the polluted water is treated, the amount of sewage discharged is large, which causes great pollution to the environment

Embodiment 1

[0032] like figure 1 As shown, a glass industry water circulation system includes glass industry water equipment 1, heat exchange equipment 2, water storage tank 3 and water supply pump 4 connected in sequence through a closed circulation pipe network. Circulation refers to pumping water in the water storage tank 3 through the water supply pump 4 and then transporting it to the glass industry water equipment 1 through the pipeline. After the water is returned to the water storage tank, the water supply pump 4 is used to draw and circulate again. Closed means that during the whole circulation process, the circulating water in the pipe network is never in direct contact with the external atmosphere.

[0033] There are generally three types of industrial water in glass industry water equipment 1: (1) In the float glass industry: for the joint workshop, including the water bag and cooling equipment in the melting section, the water bag and equipment in the forming section (the ed...

Embodiment 2

[0042] like figure 2 As shown, the glass industry water circulation system in the second embodiment of the present invention includes glass industry water equipment 1 , heat exchange equipment 2 , water storage tank 3 and water supply pump 4 sequentially connected through a closed circulation pipe network.

[0043] The water circulation system for the glass industry also includes a water supply unit connected to the water storage tank. The water supply unit includes a water supply tank 5 and a filtering device 6 and a softening device 7 connected between the water supply tank 5 and the water storage tank.

[0044] The water storage tank 3 is also communicated with a gas storage tank 9 for filling the water storage tank 3 with nitrogen or inert gas filled in the gas storage tank 9 .

[0045] The difference from Embodiment 1 is that the glass industry water circulation system in Embodiment 2 does not need to be equipped with a dosing device, but the water supply pump 4 is conne...

Embodiment 3

[0047] like image 3 As shown, the present invention also provides a water circulation system for glass industry, which includes glass industry water equipment 1, heat exchange equipment 2, and water supply pump 4 connected in sequence through a closed circulation pipe network, and also includes water supply pumps connected to heat exchange equipment 2 and water supply pump. 4, the water supply unit on the pipe network; the water supply unit includes a water supply tank 5 and a filter device 6 and a softening device 7 connected to the water supply tank 5 . The cooling water is transported to the glass industry water equipment 1 through pipelines. The temperature of the used water is high, and then transported to the heat exchange equipment 2 through pipelines for cooling. The cooled water is drawn back by the water supply pump 4 for recycling. But in order to ensure the uninterrupted operation of industrial production, its water supply pump 4 needs to increase standby power, s...

Abstract

The invention discloses a water circulating system for glass industry. The water circulating system for the glass industry comprises a glass industrial water consumption device, a heat exchanging device, a water storing box and a water supply pump which are sequentially connected through a closed pipe network. According to the water circulating system for the glass industry, circulating cooling water does not directly contact with the atmosphere to be evaporated and cooled, so that the water loss is reduced, the floor space is reduced, and meanwhile, zero emission is basically reached, the water supply pressure and the water quality are stabilized, and the stability of the production process is improved; the market competition and viability of an enterprise are greatly improved, the energy combination and reasonable utilization are realized, the environmental pollution is reduced, the maintenance cost of a device is decreased, and the applicability is wide; in terms of long-term development, high economic benefit and environmental benefit are brought, the industrial application prospect is wide, and the popularization and application are easily carried out.

Description

technical field [0001] The invention relates to an industrial water circulation system, in particular to a closed water circulation system applied in the glass industry, including the float glass production industry, flat drawn glass production industry and glass deep processing industry. Background technique [0002] The quantity and quality of drinking water are not only closely related to the daily life of each of us, but also play a great role in restricting or promoting the development of the national economy. my country is the most populous country in the world. Although the total water resources are relatively abundant, the per capita water resources are only 1 / 4 of the world average. For our country, water resources are very scarce and precious. [0003] At the same time, with the continuous improvement of my country's industrialization level, people's living standards are getting higher and higher, and engineering construction is also developing accordingly, and th...
