Problems solved by technology
At present, when the furnace is shut down due to an emergency, the cold oil replacement valve is usually opened to replace the hot oil in the furnace with the cold oil in the high level tank, or the emergency oil pump is turned on to allow the medium to circulate in the furnace, but the two modes are not effective Controlling the rise of the temperature of the organic heat carrier medium often causes the medium in the furnace to deteriorate due to overtemperature, and cannot provide effective emergency protection for the heat carrier medium.

Embodiment Construction
[0018] In order to make the content of the present invention easier to understand clearly, the present invention will be described in further detail below based on specific embodiments in conjunction with the accompanying drawings
[0019] Such as figure 1 As shown, an organic heat carrier furnace emergency protection system includes a medium circuit, a cooling water passage and a medium cooling tank 8, the cooling water passage communicates with the medium cooling tank 8, and injects cooling water into the medium cooling tank 8, and the medium The circuit includes a section of coil pipe 10, which is fixedly installed in the medium cooling tank 8, so that the medium flowing through the coil pipe 10 can exchange heat with the cooling water injected into the medium cooling tank 8, and the inlet end pipeline of the medium circuit An oil pump 5 driven by a diesel generator is installed, which can be started by an independent power supply. A water supply electric valve 13 is instal...

The invention discloses an emergency protection system for an organic heat carrier furnace. The emergency protection system comprises a medium loop, a cooling water passage and a medium cooling tank. The cooling water passage is communicated with the medium cooling tank and used for injecting cooling water into the medium cooling tank. The medium loop comprises a coiled pipe. The coiled pipe is fixedly installed in the medium cooling tank so that heat exchange can be conducted on media flowing through the coiled pipe and the cooling water injected into the medium cooling tank. An oil pump is installed in a pipeline at the inlet end of the medium loop, and a water supplement electric valve is installed in a pipeline of the cooling water passage. The emergency protection system can be used for effectively cooling the media, thereby protecting the media against high-temperature deterioration.
Description
technical field [0001] The invention relates to an emergency protection system for an organic heat carrier furnace, which belongs to the technical field of heating furnaces. Background technique [0002] When the organic heat carrier furnace is in normal operation, if there is a sudden power failure or emergency shutdown, etc., the organic heat transfer medium in the boiler should be immediately cooled to prevent the medium in the furnace from being overheated and carbonized and deteriorated. At present, when the furnace is shut down due to an emergency, the cold oil replacement valve is usually opened to replace the hot oil in the furnace with the cold oil in the high level tank, or the emergency oil pump is turned on to allow the medium to circulate in the furnace, but the two modes are not effective Proper control of the temperature rise of the organic heat transfer medium often causes the medium in the furnace to deteriorate due to overtemperature, and cannot effectively...
