The invention discloses a device for removing hydrogen sulfide in coal gas through desulfurization and regeneration integration. The device comprises a coal gas cooling unit, wherein a coal gas outletof the coal gas cooling unit is connected to a coal gas inlet of a coal gas purification unit; the coal gas outlet of the coal gas purification unit is connected with the coal gas inlet of a coal gasdesulfurization and regeneration unit; the coal gas desulfurization and regeneration unit comprises a desulfurization section located at the lower part and a regeneration section located at the upperpart; a sulfur foam generation groove is mounted at the lower part of the regeneration section; the bottom of a sulfur foam generation groove is connected to a sulfur foam storage groove through a pipeline; an outlet of the sulfur foam storage groove is connected with a sulfur melting kettle; the sulfur melting kettle is used for processing sulfur foam into sulfur and conveying the sulfur to a subsequent procedure. According to the device disclosed by the invention, desulfurization and regeneration are integrated, so that the land area is reduced; a spraying device is utilized and air is self-sucked into the regeneration section through desulfurization liquid power of the regeneration section; a compressor is not needed so that the energy consumption is saved.
