Well type furnace is mainly composed of outer cover, inner tube, convection pipe, burner, bottom stirring circulating fan, strong cooling fan, methanol cracking furnace, etc. The common well type furnace has the well type tempering furnace, the well type quenching furnace, the well type annealing furnace.
The shell is composed of steel plate shell, furnace lining top suspension beam. The shell is the structural support of the whole furnace body. The lower part has a pair of guide rings to cover the guide pillars with different heights on both sides of the hearth to ensure that the center line of the cover the hearth coincides.
2. Inner cylinder
The function of the inner cylinder is to separate the flue gas flow space the controllable atmosphere flow space of the workpiece, it is also the heat exchange surface in the heat transfer process. The inner cylinder has good sealing performance, high temperature resistance, oxidation resistance proper rigidity, which can increase heat exchange area, reduce deformation prolong service life.
3. Convection tube
The function of the convection cylinder is to ensure that the material to be processed is separated the inner cylinder provide a controlled atmosphere for the convection channel. The hot air flow first rises along the annulus between the convection cylinder the inner cylinder, then descends into the material pile. The velocity of gas in the annulus is very high remains constant, which is conducive to the heat transfer between the gas flow the inner cylinder.
4. Bottom mixing fan
A stirring fan is installed in the middle of the furnace bottom. During heating, the controlled atmosphere circulates through the annular gap between the convection tube the inner tube, the heat is obtained the inner tube transferred to the workpiece. The fan runs in the whole cooling stage forms strong convection in the loading space. The controlled atmosphere takes heat away the workpiece transfers it to the inner cover. The mixing fan adopts frequency conversion motor, which can adjust the motor speed according to the temperature in the furnace. It has the characteristics of accurate speed, convenient use maintenance.
The combustor system consists of burner, fan, pipe system exhaust pipe. Two rows of 8 burners are distributed along the tangential direction of the furnace shell, which is conducive to uniform furnace temperature reduce local overheating of the inner shell. It directly heats the inner cylinder is the heating source of pit furnace.
6. Methanol cracking furnace
The methanol cracking furnace uses the CO produced by methanol pyrolysis at high temperature enters the well furnace as mixed gas to realize the corresponding heat treatment process. It is composed of feed system, gasification chamber, heat exchanger temperature control system, which plays an important role in process stability.
