A desulfurization regeneration tower

Abstract

The invention relates to a desulfuration regeneration tower. Coal gas and a desulfurizing liquid are subjected to mass transfer in a filling material to remove hydrogen sulfide in coal gas, the desulfurizing liquid reaches an upper regeneration section through a desulfurizing liquid conveying pipe, and the coal gas is regenerated by utilization of air under the action of a catalyst, and returns to a lower desulfuration section to be subjected to desulfuration. The desulfuration regeneration tower is divided into the lower desulfuration section and the upper regeneration section, wherein the lower desulfuration section comprises a coal gas inlet, a coal gas outlet, a coal gas distributor, a filling material, a mist collecting filling material, a filter, a cyclone separator and a desulfurizing liquid outlet; the upper regeneration section comprises a bubble separator, an inclined conical section, a foam outlet, a regenerated air outlet and a gas distributor. According to the desulfuration regeneration tower, an HPF wet oxidation process desulfuration technology is adopted, so that the desulfurizing liquid and air can be better mixed, the contact time is prolonged, the influence on desulfurizing liquid temperature by environmental temperature is reduced, meanwhile space is saved, lots of materials are saved, the desulfuration efficiency is improved by utilization of self structural advantages, and the environmental pollution of a coking plant is reduced.

Description

technical field [0001] The invention relates to an HPF desulfurization regeneration tower. It is specifically used in the desulfurization device in the coking industry to remove hydrogen sulfide in the gas. Background technique [0002] As a large coal and steel country, my country has a large number of coking enterprises throughout the country, and the gas produced by these coking enterprises is rich in hydrogen sulfide. Regardless of whether the gas is used for industrial or civil purposes, it is necessary to desulfurize the gas. At present, the commonly used desulfurization process in China is mainly wet desulfurization. In the conventional wet desulfurization process, many equipment such as desulfurization towers, regeneration towers, mist traps, desulfurization liquid circulation pumps, etc. need to be arranged, and a large number of process pipelines need to be arranged. invest. In addition, if the operation is not good, it is difficult to guarantee the desulfurizat...

Problems solved by technology

In this patent, the gas directly leaves the tower body from the upper part of the desulfurization section, and the desulfurization liquid is entrained in the gas, so the purification of the gas is not complete
