The carrier equipment of the green brick in the secondary dryer is a drying car. The bricks are stacked on the drying car by the racking system. After drying, the drying car is unloaded by the lowering system, and then the bricks are stacked on the kiln car by the racking system. This operation adopts a single layer drying method, which is suitable for raw materials with high moisture content, because each green brick is fully dried, and the drying efficiency is high.
The drying medium is generally provided by the waste heat of the roasting kiln and is supplemented by the burner when the heat is insufficient. The drying room is equipped with a hot air supply system, a moisture exhaust system and a temperature and humidity monitoring system. By monitoring and adjusting the system, the supply air temperature and air volume can be controlled to ensure the drying quality of the bricks.
The structure of the secondary dryer is a multi-channel brick-concrete structure or a multi-channel frame structure without partition walls to adapt to different drying requirements.
- Q: What is the best drying equipment?
- Through the filter to make hot air purification, and then by the left shunt plate to the layers, so that the average hot air through each layer of dry material.
- Q: The working principle of belt dryer
- Drying process is a hot air flow through the material layer, complete the process of heat and mass transfer, the upper cavity connected by the duct and the fan inlet. Most of the gas circulation, part of the lower temperature of the larger moisture content of the gas as exhaust gas through the drainage tube, regulating valve, drain fan discharge. The next cycle of the unit, the fan out of the wind into the upper cavity, down through the heat exchanger heating, through the material layer into the lower chamber, the lower chamber by the side duct and return air duct connected to the fan, most of the gas circulation, Part of the discharge. Up and down the cycle unit according to user needs can be flexible equipment, the number of units can also be selected according to need.
- Q: What are the common types of dryers?
- Roller scraper dryer is through the rotation of the cylinder, in a heat conduction way, will be attached to the outer wall of the cylinder liquid material or ribbon material, dry a continuous operation of equipment to be dry treatment of liquid from the high
- Q: What are the common drying methods?
- Drying method Drying is the process of removing moisture from various materials. Various materials can be solid, liquid or gas, solid and can be divided into large pieces of material, fiber material, pellets, fine powder and so on, Is the moisture in the material, it can be other solvents. In this water for the object. Drying equipment, there are three ways to dry: (1) mechanical dehydration
- Q: How to solve the dryer a series of failures
- The moisture absorption capacity of the dryer is limited, so the moisture it adsorbs must be removed by regeneration. The process is: when the ambient air is inhaled, through a filter into the blower, and then be sent to a group of heaters. The heated air passes through the machine. When the temperature of the dryer rises, the adsorbed moisture is released. When the hot air to absorb water vapor to saturation, it was discharged into the atmosphere. The high temperature regenerative dryer must be cooled before returning to the dry loop to restore the moisture absorption function of the dryer.
- Q: How to choose the right drying equipment and drying technology
- For non-hygroscopic materials, the moisture present in any environment remains on the surface and becomes "surface moisture" and is easily removed.
- Q: The development prospects of the dryer
- performance, the use of compact heat exchangers, such as plate fin heat exchangers, is promising. (The current difficulties may still be in terms of price). Promotion of the use of green ring-type refrigerant R134a, including cold and dry machines, including all the direction of development of refrigeration equipment, technically there is no insurmountable obstacles. But this is a great social engineering, an industry, a separate action of a business in addition to some commercial publicity significance, the overall goal of the macro is not much practical effect. In the final analysis, this is a government action, the need for the introduction of policies by the state to define a unified time limit.
- Q: Frozen sublimation drying equipment which consists of several systems
- refrigeration system: refrigeration unit and freeze-drying chamber, the condenser inside the evaporator and other components. Chillers can be independent of two sets, that is, a set for the freeze-drying room, a set for the condenser, can also be combined with a set of freezer.
- Q: What are the characteristics of the drum dryer?
- According to the dry material is heated, the current rotary drum dryer can be divided into five types, that is, direct Heating dryer, indirect heating dryer, compound heating dryer, steam calcining dryer, spray granulation drying machine.
- Q: What is a combination of drying equipment?
- Combination drying equipment is a combination of two or more dry forms, the main material, mainly in series, that is, when the material has been through the drying equipment, two or more drying equipment, combined dry mainly to meet a The need for a drying process.
