Description

Heat exchanger

The present invention relates to a heat exchange device, and more particularly, to a heat exchange device for effectively recovering heat in a device that generates a high temperature, such as a scrubber.

In general, semiconductors, LEDs, LCDs, solar cells, and the like are manufactured at high temperature using gas such as hydrogen (H2) group, silane (SiH4) -based gas such as monosilane, disilane, ammonia (NH3), and the like. At this time, the waste gas such as ignitable gas and toxic gas contained in the combustion process of hydrogen group, silane gas and ammonia are discharged without filtration into the atmosphere, which has a significant adverse effect on human body and air pollution. Problems have emerged.

Accordingly, various types of treatment methods have been provided to treat waste gases such as pyrophoric and toxic gases emitted during semiconductor manufacturing. As a representative example, there is a method using a wet method or a dry method scrubber, and if necessary, a separate filter or an adsorption layer may be provided before and after the scrubber to increase treatment efficiency.

Wet-type scrubber is a structure that cleans and cools toxic gas using water, and has a relatively simple configuration. Dry scrubber is a structure that burns the burner such as air burner or oxygen burner directly to allow toxic gas to pass through, or to indirectly burn by forming a high temperature chamber using heat source and let toxic gas pass at high speed. In addition, there is an excellent effect in the treatment of the flammable gas.

Such scrubbers are generally operated to cool the hot gases rapidly to lower them to a post-treatable temperature. Therefore, the scrubber installation is generally designed and operated in the form of heat dissipation to the surroundings without considering insulation.

Here, if the energy of the high-temperature fluid generated from the scrubber and the energy radiated from the facility are recovered, the energy consumed by the scrubber can be substantially reduced.

On the other hand, the heat exchange device is widely used throughout the industry as a facility that can control the temperature, recovery of energy through the heat exchange between the high temperature fluid and the low temperature fluid.

In a process having a wide temperature range, such a heat exchanger is generally operated in a plurality of series by appropriate temperature ranges, rather than a single heat exchanger. However, the heat exchanger connected in series as described above has a problem in that the space occupying itself and the separate duct space for fluid connection with each other are required.
