specific Embodiment

[0044]Set 6 first through holes with a diameter of 30mm in the furnace cover, and adopt a threaded structure. The lower end of the outlet pipe is a smooth straight cylinder, and the furnace is a ceramic fiber furnace. The size of the furnace is 650mm long × 450mm wide × 400mm high. The appearance size is: length 950mm×width 750mm×height 800mm, and the height of the bracket is 200mm.

[0045] There are 6 tank bodies, which are cylindrical in shape and made of high temperature resistant carbon silicon material. There is a tank cover on the upper part of the tank body, and the tank cover and the tank body can be fixed into a closed space with nuts. The air inlet pipe is installed on the bottom of the side of the tank, and the air outlet pipe is installed on the sealing cover. The air inlet pipe and the air outlet pipe of each tank can extend to the outside of the furnace through the first through hole on the furnace cover, so as to prepare for gas collection and flow into the tank...

Abstract

The invention provides a coal spontaneous combustion high-temperature program heating device and a testing method using the same. The coal spontaneous combustion high-temperature program heating device comprises a furnace body, tank bodies, a temperature measuring assembly and a temperature control panel. A furnace lid is arranged on the upper portion of the furnace body, when the furnace lid covers the upper portion of the furnace body, the furnace body and the furnace lid form a hearth, a carbon steel layer is arranged outside the hearth, and a stainless steel layer is arranged outside the carbon steel layer. Gaps are both formed between the hearth and the carbon steel layer and between the carbon steel layer and the stainless steel layer. The tank bodies are placed inside the hearth, heating units are arranged both the side wall and the bottom of the furnace body, the temperature measuring assembly used for monitoring the temperature inside the hearth is arranged on the side wall of the furnace body, and the heating units and the temperature measuring assembly are both connected with the temperature control panel. By means of the coal spontaneous combustion high-temperature program heating device and the testing method using the same, the temperature of a coal spontaneous combustion program temperature rising experiment can be raised to 1,000 DEG C, high-temperature program heating can be conducted on coal samples through the experimental device, a relevant coal spontaneous combustion model is established, and good guidance can be provided for fire prevention in coal fields.

Description

technical field [0001] The invention belongs to the technical field of experimental test devices, and in particular relates to a coal spontaneous combustion high-temperature programmed temperature rise device and a test method using the device. Background technique [0002] Coalfield fire is a global disaster, which seriously threatens human health, natural environment and coal mine safety production, and causes huge resource loss and environmental pollution. The formation and evolution process of coalfield fire areas is complex, with long burning time, wide range, hidden high-temperature fire source, and difficult control, which has become a problem that needs to be solved urgently. There are many experimental devices for testing the characteristic parameters of coal spontaneous combustion, mainly including large-scale coal spontaneous combustion test bench and coal spontaneous combustion low-temperature programmed temperature rise test device. However, these two test benc...
