Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
Referring to fig. 1 and 2, the vertical tube furnace for inspecting the burning behavior of hazardous waste material of the present invention includes a heating box 8 and a furnace tube 5 disposed in the heating box 8; wherein the content of the first and second substances,
a vertical observation window 9 is arranged on the heating box body 8, and scale marks are printed beside the observation window 9;
a feed inlet is arranged in the center of the top plate of the furnace tube 5, and a cooling air inlet tube 2 is inserted in the feed inlet; a feeding air inlet pipe 1 is coaxially inserted into the cooling air inlet pipe 2;
an annular partition plate 50 is arranged at the top of an inner cavity of the furnace tube 5, an inner hole of the partition plate 50 is hermetically sleeved at the lower end of the cooling air inlet tube 2, the partition plate 50 and a top plate of the furnace tube jointly form a cooling water tank 6, and a cooling water inlet 3 and a cooling water outlet 4 which are communicated with the cooling water tank 6 are also arranged on the top plate of the furnace tube 5, so that water in the cooling water tank 6 is circulating water;
a cooling sleeve 10 made of quartz is arranged at the outlet at the lower end of the furnace tube 5.
The utility model discloses a vertical tube furnace for examining danger waste material burning behavior, at the during operation, boiler tube 5 comprises two way air intakes, respectively from the feeding air that feeding air-supply line 1 got into and the cooling air that gets into from cooling air-supply line 2.
