Abstract
设有热风循环管的木纤维板生产线干燥系统，包括木纤维板生产线干燥系统，它还有热风循环管，热风循环管进口端与木纤维板生产线干燥系统的旋风分离器的排气总管尾端相通，热风循环管设有二个排气出口，其中一个排气出口与木纤维板生产线干燥系统的干燥筒相通，另一个排气出口与木纤维板生产线干燥系统的燃煤锅炉的烟囱相通。优点是由于在旋风分离器的气流出口的排气总管上设有热风循环管，它可将排气总管上内热气流一部分输送至干燥筒内，用于调节干燥系统的气流；另一部分通过燃煤锅炉的烟囱排出。从而可减少排气总管内的热气流，降低排气总管内的温度，避免了排气总管内起火的现象发生。
Wood fiberboard production line drying system with hot air circulation pipe, including wood fiberboard production line drying system, it also has a hot air circulation pipe, the inlet end of the hot air circulation pipe is connected with the tail end of the main exhaust pipe of the cyclone separator of the wood fiberboard production line drying system, and the hot air The circulation pipe is provided with two exhaust outlets, one of which communicates with the drying cylinder of the drying system of the wood fiber board production line, and the other communicates with the chimney of the coal-fired boiler of the drying system of the wood fiber board production line. The advantage is that there is a hot air circulation pipe on the exhaust main pipe of the air outlet of the cyclone separator, which can transport part of the hot air flow on the exhaust main pipe to the drying cylinder for adjusting the air flow of the drying system; Boiler chimney exhaust. Thereby, the hot air flow in the exhaust main pipe can be reduced, the temperature in the exhaust main pipe can be lowered, and the occurrence of fire in the exhaust main pipe can be avoided.
Description
Technical field
The utility model relates to wood-fiber board production line field.Tool drying system body ground is said and is related to a kind of wood-fiber board production line drying system that is provided with the hot air circulation pipe.
Background technology
Existing wood-fiber board production line drying system; Comprise that rotary drying drum, material pipe, selection by winnowing air exhauster, cyclone separator and coal-burning boiler constitute; Material Guan Yiduan communicates with the rotary drying drum discharging opening, and the other end communicates with the cyclone separator import, and the selection by winnowing air exhauster is installed in the material pipe; Air stream outlet at cyclone separator is provided with exhaust main, on exhaust main, is provided with one group of whirly deduster.Its weak point is also to contain a large amount of wood-fibreds in the thermal current in the exhaust main of air stream outlet of cyclone separator, because thermal current is bigger in the exhaust main, temperature is higher, and wood-fibred body on fire often takes place, and influence is produced.
The utility model content
The purpose of the utility model is exactly to frequent fine whose body on fire of wood that takes place in the exhaust main of the air stream outlet of cyclone separator, the deficiency of influence production, and a kind of wood-fiber board production line drying system that is provided with the hot air circulation pipe is provided.
The utility model comprises wood-fiber board production line drying system; It also has the hot air circulation pipe; Hot air circulation pipe entrance point communicates with the exhaust main tail end of the cyclone separator of wood-fiber board production line drying system; The hot air circulation pipe is provided with two air exits, and one of them air exit communicates with the drying of wood-fiber board production line drying system, and another air exit communicates with the chimney of the coal-burning boiler of wood-fiber board production line drying system.
The utility model has the advantages that owing on the exhaust main of the air stream outlet of cyclone separator, be provided with the hot air circulation pipe it can be delivered to a thermal current part on the exhaust main in the drying, is used to regulate the air-flow of drying system; Another part is discharged through the chimney of coal-burning boiler.Thereby can reduce the thermal current in the exhaust main, reduce the temperature in the exhaust main, avoid that phenomenon on fire takes place in the exhaust main.
Description of drawings
Accompanying drawing 1 is the utility model structural representation.
The specific embodiment
Shown in accompanying drawing; The utility model comprises wood-fiber board production line drying system (commercially available prod), comprises that rotary drying drum 3, material pipe 4, selection by winnowing air exhauster 5, cyclone separator 6 and coal-burning boiler 7 constitute, and material pipe 4 one ends communicate with the rotary drying drum discharging opening; The other end communicates with cyclone separator 6 imports; Selection by winnowing air exhauster 5 is installed in the material pipe 4, is provided with exhaust main 2 at the air stream outlet of cyclone separator 6, on exhaust main 2, is provided with one group of whirly deduster 8.It also has hot air circulation pipe 1; Hot air circulation pipe 1 entrance point communicates with exhaust main 2 tail ends of the cyclone separator of wood-fiber board production line drying system; Hot air circulation pipe 1 is provided with two air exits; One of them air exit communicates with the drying of wood-fiber board production line drying system, and another air exit communicates with the chimney of the coal-burning boiler of wood-fiber board production line drying system.
