Description

An intelligent digestion and cooling all-in-one machine

technical field

The invention relates to the technical field of environmental protection equipment, and more specifically relates to an intelligent digestion and cooling integrated machine for pretreatment of water samples.

Background technique

In recent years, with the deepening of reforms, increased basic investment, large-scale transformation of infrastructure and upgrading of industrialization, domestic and industrial water consumption has continued to increase, and wastewater discharged to rivers, lakes and seas has gradually increased, causing varying degrees of damage to the environment and ecology. Destruction, coupled with weak supervision in some areas, and brutal mining, resulting in serious deterioration of water quality, CODcr, ammonia nitrogen, total phosphorus, heavy metals, etc. seriously exceeded the standard. With the improvement of living standards, people's requirements for the quality of life are getting higher and higher. At the same time, the government pays more and more attention to the control and supervision of environmental pollution, especially the supervision of water quality. Indexes to evaluate water quality can no longer fully reflect the quality of water bodies. For key pollution sources, surface water, river sections, sewage treatment plants, etc., the state uses multi-parameter monitoring instruments to form a "water quality online automatic monitoring system" to monitor water quality online in real time and record changes in water quality. The data is transmitted to the monitoring center, monitoring station, and related functional departments, and the sampled water will be pretreated in the work of water quality testing.

Water pretreatment is the preliminary treatment before the water refining treatment, so as to achieve good results and improve water quality when the water is treated. Because natural water has a lot of impurities, such as sediment, clay, organic matter, microorganisms, mechanical impurities, etc., the existence of these impurities seriously affects the water quality and treatment effect of refined water, so some impurities must be reduced or removed before fine treatment , which requires preprocessing, sometimes called preprocessing.

When the sample water is pretreated, the sample water will be digested. At present, the air-cooled reflux mode is used in the digestion process of the standard sample. When cooling, it is usually used to increase the air cooling system to save the cooling time. However, due to the increased cooling The system thus increases the noise, which brings shortcomings in the environmental protection of the instrument, and the air cooling will cause uneven cooling. There is also a water-cooled reflux mode for cooling. Although it can also improve the cooling efficiency, it also brings waste of water resources and energy consumption. Adding a water-cooling system increases the structure of the instrument at the same time, which is not conducive to the compact design of the instrument and high cost. . In addition, the equipment for digestion and cooling of water samples is now separated. During the experiment, it is inevitable that there will be errors due to too many equipment. Therefore, an intelligent digestion and cooling all-in-one machine is designed to solve the above problems.
