Embodiment Construction

[0024] The present invention will be further described below in conjunction with accompanying drawing.

[0025] Such as figure 1 As shown, the first subject of the present invention is an on-line sampling device for high-temperature corrosive powder, which includes a high-temperature silo 1 for accommodating the powder. The bottom of the high-temperature silo 1 is provided with a sampling port, and the sampling port is connected to one end of the discharge pipe 2 , the other end of the discharge pipe 2 is a discharge port, and two valves are arranged at intervals on the discharge pipe 2, and the two valves are respectively a first valve 3 and a second valve 4.

[0026] The high-temperature silo 1 is used to accommodate high-temperature corrosive powder, such as hot titanium tailings. The sampling port at the bottom of the high-temperature silo 1 is the passage for the material to enter the discharge pipe 2, for example, the sampling port of the high-temperature silo 1 is a ro...

Abstract

The invention discloses an online high-temperature corrosive powder sampling device and method, relates to the field of chemical industry, and solves the problems of high environmental pollution and high safety risk due to online sampling of high-temperature, fine-granularity and strong-corrosivity powder in a conventional sampling mode. According to the technical scheme, the online high-temperature corrosive powder sampling device comprises a high-temperature material bin; a sampling hole is formed in the bottom of the high-temperature material bin; the sampling hole is connected with a discharging pipe; and at least two valves are arranged on a discharging pipe. According to the online high-temperature corrosive powder sampling method, before sampling, a valve, closest to the sampling hole, on the discharging pipe is closed; during sampling, a valve which is second closest to the sampling hole is closed, the valve closest to the sampling hole is opened, and materials enter the discharging pipe; and a valve of a pipe section containing the materials in the discharging pipe is closed, and a valve, close to one side of a discharging hole, of the pipe section is opened until the materials flow out of the discharging hole. The sampling device and method are suitable for online sampling the high-temperature corrosive powder.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a device for on-line sampling of high-temperature, fine-grained, and highly corrosive powders, such as hot titanium tailings, and a sampling method through the sampling device. Background technique [0002] Panzhihua Iron and Steel Group discharges about 6-7 million tons of titanium-containing blast furnace slag every year, of which the content of titanium dioxide in blast furnace slag is between 20 and 26%. Outfit. The process has completed the construction of the demonstration line and is running stably. However, after extracting the titanium resources in the blast furnace slag by this process, a large amount of chlorinated tailings will be produced, and the chlorinated tailings are the titanium extraction tailings. In order to achieve the goal of the process as a "green ecological" process, the tailings of titanium extraction must be utilized on a large scale. [0003] The ...
