Description

Technical Field

[0001] The utility model belongs to the technical field of cooling devices, and in particular relates to a cooling device for producing plant charcoal. Background Art

[0002] At present, the production equipment of plant charcoal is diversified, and the cooling of the charcoal that can be produced mostly adopts conventional water spray cooling and then natural cooling. This method not only pollutes the environment, but is also limited by natural conditions. For this reason, a new type of plant charcoal production cooling device is adopted. The cooling device consists of a cooling material box and a cooling water tank. The cooling material box is composed of double-layer materials. There is a certain gap between the double layers, and the two layers are fully enclosed. There is circulating cooling water inside, so that the four walls and the bottom of the cooling material box are cooling surfaces. A cooling circulation pipe is placed in the cooling material box, so that the middle part of the cooling material box also has a cooling effect. The plant charcoal to be cooled in the cooling material box is aerobically cooled for a very short period of time just after entering the box. As the plant charcoal flows into the covering Cover, the cooling of plant charcoal is mostly anaerobic cooling, which ensures the quality of plant charcoal. At the same time, because the cooling device is forced cooling and mostly anaerobic cooling, the temperature of the charcoal to be cooled can be appropriately increased (30-50℃ higher than normal temperature cooling), thereby reducing the amount of water for water spray cooling. Moreover, the high charcoal temperature is conducive to the evaporation of water, so the moisture content of the charcoal can be controlled by adjusting the water spray amount of the charcoal to be cooled and the cooling time in the box. The cooling water tank is made of single-layer material and is filled with cooling circulating water. The auger is immersed in water, thereby realizing secondary anaerobic cooling of the plant charcoal. The exhaust device on the cooling material box effectively discharges the water vapor generated by the water spray to extinguish the plant charcoal and the harmful substances volatile from the plant charcoal.

[0003] The existing cooling device for plant charcoal production has the following defects in use:

[0004] (1) In the existing cooling device for producing plant charcoal, cooling circulating water is delivered to the corresponding cooling pipe position through the water inlet to achieve charcoal cooling. However, during the cooling process of the cooling circulating water, impurities contained in the cooling circulating water enter the cooling pipe of the device. During the energy conversion cooling process, the impurities adhere to the inner wall of the pipe to form scale, causing the cooling pipe wall to become thicker and affect the cooling effect. At the same time, the impurities also cause the sprinkler nozzle to be blocked, thus affecting the cooling effect. For this reason, we propose a cooling device for producing plant charcoal.
