Problems solved by technology

[0011] Problems of thermal analysis: 1. The gas generated during the analysis process is unsafe and difficult to dispose of, especially for the heating of powdered coke. The gas generated by the reaction is high-temperature water vapor containing adsorbed substances
2. The thermal analysis reaction temperature is high, and the powdered coke has high reactivity, which is easy to react with substances in the external environment, resulting in adverse effects on the hazard analysis effect and operation safety
3. Low heat transfer efficiency
Low heat exchange efficiency caused by excessive air volume caused by uneven air distribution

Embodiment Construction

[0030] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0031] Such as figure 1 As shown, in order to monitor and maintain a certain material level with a material level meter (not shown in the figure) for the feeding of the lower hopper 1 during analysis, to prevent gas leakage in the tower, the lower hopper 1 itself includes a feed pipe, Or between the lower hopper and the feeding screw feeder, a powdered coke feeding pipe for connection is separately provided. The feeding pipe should have a certain length or height so that the lower hopper 1 and the feeding screw feeder The feeding port 2 of 3 is at a certain height. At the same time, a certain level of material needs to be maintained in the lower hopper to seal the gas in the analysis device and prevent the gas in t...

Abstract

The invention provides a powdery coke desorption device. The powdery coke desorption device comprises an unloading cabin (1), an inlet material screw feeder (3), a rotary desorption tower (9), a rotary motor (7), and an outlet material screw unloading machine (14). The unloading cabin (1) is connected to a material inlet (2) of the inlet material screw feeder (3) by a feeding pipe. The rotary desorption tower (9) comprises a heat exchange tube (8) combined with the tower body. The inlet material screw feeder (3) installed on an upper part of the rotary desorption tower (9), the outlet material screw unloading machine (14) installed on a lower part of the rotary desorption tower (9), and the rotary desorption tower (9) are arranged in a housing filled with nitrogen. Joints of the rotary desorption tower (9), and the inlet material screw feeder (3) and the outlet material screw unloading machine (14) are sealed by high temperature-resistant seal rings (6, 12). The rotary motor (7) is connected to the exterior of the tower body of the rotary desorption tower (9).

Description

technical field [0001] The invention relates to an analysis device and analysis method, in particular to an analysis device and analysis method for powdered coke. Background technique [0002] Activated coke dry desulfurization technology is often used in flue gas purification of industrial coal-fired boilers, and is also used in the purification of gas in absorption towers in the fields of chemical industry, metallurgy, glass, and pharmaceuticals. Due to its physical characteristics, powder coke is superior to cylindrical coke, and its desulfurization effect is relatively ideal. But its analysis is difficult and the recovery rate is low. Choosing an economical and reasonable analysis device can have a positive effect on the promotion of powder coke desulfurization technology. [0003] <Development of activated coke desulfurization technology> [0004] Activated coke desulfurization technology was developed in the 1960s. It is a dry desulfurization and denitrificati...
