Abstract

The invention relates to a dehumidifier, in particular to a structure improvement of a dehumidifier capable of recycling a cooled heat source of coal gas. The dehumidifier comprises a shell as well as a pre-cooling heat exchanger (2), a cold water cooler (3), a brine cooler (4) and a recuperative heater (5) which are arranged inside the shell and connected in sequence. The dehumidifier is characterized in that the internal medium of the pre-cooling heat exchanger (2) and the internal medium of the recuperative heater (5) are connected through a recycling pipe (6). Therefore, the dehumidifier provided by the invention has the advantages of satisfying a basic dehumidifying function, realizing residual-heat utilization inside a system and reducing operation cost by flexibly using the two-level dehumidifier comprising the cold water cooler and the brine cooler in operation.

Description

technical field [0001] The invention relates to a dehumidifier, in particular to an improved structure of a dehumidifier capable of recovering gas cooling heat sources. Background technique [0002] At present, many iron and steel enterprises produce a large amount of gas during the blast furnace smelting process. In order to effectively use this energy, most of them use gas turbines as prime movers to drive generators to generate electricity. Before the gas enters the gas turbine, pretreatment such as dust removal, cooling and dehumidification is required to meet the gas quality requirements of the gas turbine. Contents of the invention [0003] The present invention mainly solves the technical problems of high dehumidification process cost in the prior art and cannot realize waste heat utilization inside the system; it provides a method that satisfies the basic dehumidification function and realizes waste heat utilization inside the system, A dehumidifier that flexibly ...
