Water control equipment for blast furnace gas

Abstract

The invention discloses water control equipment for blast furnace gas, the water control equipment comprises a cooling unit, a first water removal unit and a second water removal unit which are connected in sequence, the cooling unit is provided with a gas inlet and a cooled gas outlet, the first water removal unit is provided with a cooled gas inlet, a first water removal gas outlet and a first water outlet, and the second water removal unit is provided with a second water outlet. And the second dewatering unit is provided with a first water inlet, a second dewatered coal gas outlet and a second water outlet. When the water control equipment is used for treating the blast furnace gas, the blast furnace gas firstly enters the cooling unit, is cooled and then enters the first water removal unit to be continuously and efficiently dehydrated, and gas-containing water obtained by removal periodically enters the second water removal unit to be further subjected to gas-liquid separation, so that gas leakage can be completely eradicated. In addition, the water control equipment is easily integrated with a front-end process tank body, is compact and attractive in structure and small in occupied space, and does not increase resistance to the overall operation of the system.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular, the invention relates to water control equipment for blast furnace gas. Background technique [0002] Domestic blast furnace gas desulfurization work is in its infancy, and various technical processes are mostly in the period of exploration and verification. Taking hydrolysis catalysis plus dry absorption process as an example, it was found in the preliminary laboratory test and later engineering application verification that if there is too much liquid free water in blast furnace gas and is not controlled, it will affect the hydrolysis catalyst and dry water in the gas desulfurization process device. The desulfurization agent produced a relatively significant impact. Most of the existing technologies have no targeted measures, and a small number of systems that have found problems have added mechanical water removal devices. However, because it is not an overall consideration and...

AI Technical Summary

Problems solved by technology

[0003]1. The water removal performance of the water removal equipment is poor;

[0004]2. The equipment occupies a large area;

[0005]3. Active control and expansion control are not allowed;

[0006]4. The drainage structure is unreasonable, there is a risk of gas leakage, and there is a great potential safety hazard

[0007] In summary, the existing water control equipment for blast furnace gas still needs to be improved
