What are the technical advantages of belt dryer operation?

Desiccant, as the name implies, is a chemical substance that prevents food from getting wet. The dryer can also be explained by name, and the explanation is a kind of mechanical equipment that prevents some kind of damp.

The application of belt dryers in sludge treatment is very common. Whether it is municipal construction, industrial production, or domestic sewage sludge treatment, the shadow of the sludge dryer can be seen. So, what is the role of the pharmaceutical sludge dryer in daily life? Why do we need to dry the sludge?

Since various chemical sludges contain a large amount of heavy metals, if they are dumped in the coastal cities, they will have a great impact on the marine ecological environment. At the same time, fish and shrimp in the sea and other creatures return to people's table, which greatly endangers people's physical and mental health. In addition, improper treatment of sludge landfill will also allow concentrated sewage to penetrate underground and form secondary pollution to groundwater.

When we simply fill land or open piles of sludge with high water content, easy and odor, it is easy to cause serious damage to the soil. For example, some chemical components in the sludge can kill microorganisms in the soil, thereby destroying the soil structure and losing soil fertility and vitality. Moreover, after the harmful substances in the sludge are absorbed by the plants, they will return to the food chain, which is very harmful to the human body.

In the past, medical wastewater dryers for agricultural products were mainly used to spread the products on the field for a few days or a few hours. The advantage of this natural drying method is that it does not consume conventional energy, as long as there is sufficient production area and a certain amount of manpower. There is almost no cost. However, the disadvantages of this drying method are also obvious. If the drying temperature is low, the time required is long, the drying conditions are uncontrollable, and the quality of drying is difficult to ensure. Some agricultural products are also susceptible to moisture at night due to the slow drying speed.

In this open-air environment, there may be rats and sandstorms, which are very attacked and deteriorated. If there is a sudden rainstorm, it will be urgently robbed. It will cause more waste of manpower and material resources. Therefore, artificial drying has occurred, but time The energy problem is becoming more and more prominent, the conventional energy will eventually end, and the environmental pollution will be caused by a large amount of burning resources. At this time, the development and utilization of unconventional green energy has become a research hotspot. It has a long-term significance for China's sustainable development and the benefit of mankind, so the emergence of solar drying has become an important development direction.

Belt dryers are not an uncommon machine. Dryers are important in large enterprises, and it is estimated that we don't know even if we see them. The dryer is not a large-scale machine. It can only be said to be medium and small mechanical equipment. Most of the dryers should be used in the south. This equipment is rarely seen in the north because the north is relatively dry and the south is relatively moist.

The main working principle of the belt dryer is to use a mechanical device that can reduce moisture for drying an object. The dryer is heated by a certain pipe in the machine to evaporate the water in the material to obtain the specified substance. In fact, the main purpose of the zuizui dryer is to further process the use of certain substances.

Belt dryers can be said to be an indispensable small mechanical device in the future machinery factory!

What are the advantages of belt dryers?

1. Well-designed adsorption tower body.

2. High performance activated alumina adsorbent.

3. Imported pneumatic controller with two characteristics of high power and durability.

4. Regenerative gas regulating valve that can precisely adjust the flow rate

According to the heating method, the dryer is divided into a convection type, a conduction type, a radiation type, a dielectric type and the like. The convection dryer, also known as the direct dryer, uses a hot drying medium to directly contact the wet material to transfer heat in a convective manner and take away the generated steam. The conductive dryer is also called an indirect dryer, and the conduction method is used. The heat source transfers heat to the wet material through the inter-metal wall, and the generated wet steam can be removed by vacuum suction, a small amount of purge gas or condensation on the surface of a separately disposed cryogenic condenser. This type of medical wastewater dryer does not use drying medium, has high thermal efficiency, and the product is not polluted, but the drying capacity is limited by the heat transfer area of ​​the metal wall, the structure is also complicated, and it is often operated under vacuum; the radiant dryer utilizes each The radiator emits electromagnetic waves of a certain wavelength range, and is selectively absorbed by the surface of the wet material and then converted into heat for drying; the dielectric dryer uses a high-frequency electric field to cause a thermal effect inside the wet material to be dried.

Advantages of medical wastewater dryer:

1 High-performance evaporator, large heat exchange area, small heat transfer temperature difference, more stable evaporator air temperature

2 Adopt high-efficiency gas-water separation structure, high oil-water separation efficiency;

When we simply fill land or open piles of sludge with high water content, easy and odor, it is easy to cause serious damage to the soil. For example, some chemical components in the sludge can kill microorganisms in the soil, thereby destroying the soil structure and losing soil fertility and vitality. Moreover, after the harmful substances in the sludge are absorbed by the plants, they will return to the food chain, which is very harmful to the human body.

As a important equipment for the rational disposal of sludge, the pharmaceutical sludge dryer will inevitably have various problems in the process of use. Once the sludge dryer equipment fails, it will affect the smooth operation of the drying operation, thus reducing the final output of Zui. Here, we will give a brief summary of the common problems in the use of sludge dryer equipment.

1. The filtrate is cloudy. When we use the sludge dryer to treat the sludge, if the filtrate is turbid, it is likely that the seam of the filter belt is unreasonable, or the joint is damaged, or the filter bag is aged. For this situation, Zui's good solution is to repair the filter belt in time, or replace the new filter belt.

2. The filter belt is clogged. In the case where the concentrated sludge dryer is not thoroughly washed, the filter belt tension is too large, the fine particle sediment content in the mud is too much, and the dehydrating agent is excessively added to make the sludge viscosity too large, the filter belt is likely to be serious. Block the filter belt. Therefore, when using the sludge dryer, we should regularly flush the equipment, adjust the belt speed, strengthen the sewage sedimentation, and reduce the dosage.

3. The filter belt slips. If the sludge load of the chemical sludge dryer is too large, the tension of the filter belt is too small, or the roller is damaged, we need to reduce the amount of mud, increase the tension of the filter belt, and replace the damaged roller in time.

4, the filter belt runs off. Under normal circumstances, the reasons for the deviation of the filter belt are uneven mud amount, local wear of the roller cylinder, and insensitivity to the correcting measures. The solution to this situation is to adjust the mud inlet or flat mud device, periodically check the roller cylinder to replace the damage in time, and check the repair and correction device.
