Embodiment Construction

[0027] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0028] refer to figure 1 , The invention discloses a multi-purpose tube furnace, which mainly consists of four major parts: a fixed frame 1, a furnace 2, a furnace tube 3 and accessories 4. Such as figure 1 As shown, the furnace tube is installed in the furnace, and the fixing frame is fixed on the bottom surface, respectively connecting the furnace and the furnace tube, and the relative position of the furnace tube and the furnace can be changed, and the accessories are connected with the furnace tube.

[0029] refer to figure 2 , the key of the present invention is furnace pipe 3, and it comprises metal pipe 3-1, flange 3-2, gaseous phase pipe 3-3, sampling pipe 3-4, air guide pipe 3-5, charging pipe 3-6, thermoelectric Couple 3-7, pressure gauge 3-8, check valve 3-9, cooler 3-10 and thermal resistance 3-11.

Abstract

The invention discloses a mechanism test method of a multipurpose tube furnace, which includes a preparation stage and a test stage; the test stage includes: rotating the furnace to directly below the furnace tube, quickly inserting the furnace tube downward into the constant temperature area of ​​the furnace, and waiting for the temperature After stabilization, record the reaction start time; fine-tune the back pressure valve so that the first pressure gauge indicates the specified pressure; when the first thermal resistance shows that the temperature exceeds the threshold, slightly open the water inlet valve of the cooler to maintain the temperature at the threshold temperature Below; when the reaction time is close to the end, stop heating, cut off the power supply, prepare the water bucket, open the furnace door, rotate the furnace, and stagger with the furnace tube, put the water bucket directly under the furnace tube, and raise it as high as possible, quickly turn the furnace The tube is submerged in the bucket; after a cooling period, the bucket is removed, the gas is stopped, the pressure is released, the flange is opened, and the sample is taken out. The method of the present invention is applicable to high temperature and high pressure, and the temperature can be strongly lowered at any time, and the high temperature oil gas is not easy to flow back to the reaction material.

Description

technical field [0001] The invention relates to a test method for a tube furnace, more specifically, a mechanism test method for a multipurpose tube furnace. Background technique [0002] There are many tube furnaces on the market, but what they all have in common is that the scope of use is relatively limited and the specificity is strong. [0003] List several tube furnaces in the prior art below: [0004] The patent "multi-temperature zone tube furnace", CN 103115491 A, which solves the disadvantage that most of the furnace space is idle and wasted; [0005] The patent "A Multifunctional Tube Furnace", CN 102778036 A, solves the defect that traditional heating furnaces cannot heat multiple media; [0006] The patent "A Tube Furnace", CN 104197699 A, focuses on the heating and cooling rate; [0007] The patent "vacuum variable temperature tube furnace", CN 102607270 A, focuses on solving the problem of temperature field uniformity. [0008] When carrying out experiment...
