Problems solved by technology

The heat exchange equipment is partition wall heat exchange, that is, the hot and cold fluids flow through the two sides of the wall respectively. Since the water is violently vaporized in the pipe, it is easy to cause damage to the heat exchange pipe. If the damage leaks, the cooling water enters the reactor. would cause heavy losses

Embodiment 1

[0012] A heat pipe used in ammoxidation reaction. The heat pipe is composed of an evaporation section and a condensation section. The evaporation section is in contact with a high-temperature fluid, and the condensation section is in contact with a low-temperature channel. The heat pipe is equivalent to a heat pipe reactor for secondary partition heat exchange. A group of heat pipes Installed into the ammoxidation reactor, the heat pipe divides the reactor into two parts. One side of the reactor is the high-temperature fluid in production, and the other side is the low-temperature channel. The high-temperature flue gas in the reactor is discharged from the left channel, and the discharged The high-temperature flue gas washes the evaporation section of the heat pipe. When the flue gas temperature is greater than 35°C, the heat pipe is activated and automatically transfers heat to the right condensation section. At this time, the temperature of the high-temperature flue gas flows ...

Abstract

The invention relates to a heat pipe applied to amino oxidation reaction. The heat pipe consists of an evaporation section and a condensation section, wherein the evaporation section is contacted with high-temperature fluid, and the condensation section is communicated with a low-temperature passage; and a set of heat pipe is arranged in an amino oxidation reactor to divide the reactor into two parts, the high-temperature fluid discharged in the reactor flushes the evaporation section of the heat pipe, the heat pipe flushed by the high-temperature fluid transfer the heat to the condensation section, the low-temperature gas flows in the opposite direction along the condensation section to flush the heat pipe for absorption, and the waste heat is reclaimed in the heat pipe. Compared with the prior art, the heat pipe transfers the heat by adopting a reclaiming mode, has high efficiency and good safety performance, and effectively prevents the cooling liquid leaked due to the damage of the heat pipe from entering the reactor; and the reclaimed waste heat can be reused.

Description

technical field [0001] The invention relates to a heat pipe, in particular to a heat pipe applied to an ammoxidation reaction. Background technique [0002] Ammoxidation technology is the most convenient chemical reaction for converting a methyl group on a benzene ring or a benzene-like ring into a cyano group. The reaction is an exothermic reaction, and the heat of reaction is usually removed by installing a cooling water pipe in the reactor. By passing hot water into the cooling water pipe, the heat is taken out by vaporization to obtain steam. The heat exchange equipment is partition wall heat exchange, that is, the hot and cold fluids flow through the two sides of the wall respectively. Since the water is violently vaporized in the pipe, it is easy to cause damage to the heat exchange pipe. If the damage leaks, the cooling water enters the reactor. would cause heavy losses. Contents of the invention [0003] The object of the present invention is to provide a heat pi...
