Tunnel roasting kiln can be divided into straight tunnel kiln (with kiln car) and mobile rotary tunnel kiln (without kiln car). Straight tunnel kilns can be further divided into masonry tunnel kilns and prefabricated tunnel kilns in terms of construction methods. The mobile rotary tunnel kiln belongs to the assembled tunnel kiln.
Straight Tunnel Kiln:
(1) Main products: sintered bricks, common bricks, porous bricks, hollow bricks/blocks, roof tiles, hollow wall panels.
(2) According to the different output, the inner width of the tunnel kiln is divided into the following types:
① the inner width is 3.6 and 3.7 meters, suitable for daily output of 150,000-200,000 blocks, and annual output of 50-66 million (common bricks)
② the inner width is 4.6 and 4.8 meters, suitable for daily output of 210,000-250,000 blocks, and annual output of 69-82 million (common bricks)
③ the inner width is 5.4 and 5.6 meters, suitable for daily production of 260,000-300,000 pieces, and annual output of 85-100 million (common bricks)
④ the inner width is 6.9 and 7.2 meters, suitable for daily output of 310,000-400,000 blocks, and annual output of 102-132 million (common bricks)
⑤ the inner width is 9.2 and 9.4 meters, suitable for daily output of 600,000-620,000 pieces, and annual output of 165-200 million (common bricks)
(3) Kiln Body Structure
Assembly Type Tunnel Kiln
The kiln wall and kiln roof are factory processed into different units and spliced on site. The structural form of kiln wall is non-sintered clay refractory concrete wall panel + high-strength heat-resistant stainless-steel component + refractory fiber module + steel structure + enclosure pressure steel plate. The structural form often used on the kiln roof: light mullite plate + high-strength heat-resistant stainless-steel components + aluminum silicate refractory fiber blanket + steel structure.
(4) Firing temperature: 950-1050℃
(5) Firing cycle: 26-40h
(6) Length of tunnel kiln: 110-170m
(7) Length and size of kiln car: It is determined according to the size of the billet stack and the internal and external combustion method. The length and size of the commonly used kiln car are: 3600mm, 3900mm, 4100mm, 4200mm, 4350mm, 4800mm, etc.
(8) Firing method: all internal combustion roasting; all external combustion roasting; combined internal and external combustion roasting.
(9) The roasting kiln is often equipped with a smoke exhaust system, a combustion system, a waste heat system, a backburning system, a cooling system, and a bottom pressure balance system. Each system consists of fans, pipes and regulating valves. The kiln has a large section, high output, small temperature difference between sections, and good thermal insulation performance. Computer automatic monitoring and control system to ensure the stability of thermal parameters and roasting quality.
- Q: What is the best drying equipment?
- In the traditional horizontal fan-type dryer, the air flow only in the material surface flow, the drawback is the low heat transfer coefficient, poor heat utilization, material drying time is long.
- Q: The working principle of belt dryer
- For dehydrated vegetables, the general use of three devices in series, the formation of early dry section, the middle section and the final section. In the early dry section, due to high water content of materials. Poor ventilation, so the use of a smaller thickness of the shop material, faster running speed and higher drying temperature. In the early dry section, the dry gas temperature can be as high as 120oC or more. The length of the material in the final section is 3-6 times of the initial dry section, and the thickness of the material is 2-4 times of the initial dry section.
- Q: What are the basic types of common drying equipment?
- (4) hollow paddle dryer (leaf dryer) hollow paddle dry dryer, also known as leaf dryer, mainly by the jacket with the W-shaped shell and two hollow blade shaft and transmission components. A hollow blade is arranged on the shaft and a rotary joint with a heat medium inlet is provided at the shaft end. The heat required to dry the moisture is conducted to the material by the inner wall of the W-shaped groove with the jacket and the hollow leaf wall.
- Q: What are the common drying methods?
- Is the use of moisture to remove gas, liquid, solid material in a small amount of water, due to moisture dehumidifier dehumidification capacity is limited, only used to remove trace moisture in the material, so the production of very little.
- 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
- Hygroscopic materials can absorb moisture from the surrounding environment, non-hygroscopic materials can not absorb moisture from the environment.
- Q: The development prospects of the dryer
- Compared with the adsorption dryer, the cold and dry machine is relatively energy efficient in its applicable field. But the cold and dry machine in the small load operation also exists "big horse car" energy waste phenomenon. People want the cold and dry power consumption can follow the load changes and adjust themselves to achieve the best energy saving effect,
- 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?
- The main body of the rotary drum dryer is a slightly tilted and rotatable drum, and the wet material is fed from one end thereof and passes through the inside of the drum and is dried in contact with the hot air or the heated wall in the cylinder. , Chemical industry, metallurgy, building materials and other industries have a wide range of applications. Rotary drum drying and other drying equipment compared to the production capacity, continuous operation and simple structure, easy operation and less trouble, low maintenance costs
- Q: What is a combination of drying equipment?
- As we all know, each dryer there are some shortcomings, through the same or two or more models in series, using their own advantages, often play a single device can not achieve the purpose.
