Abstract
A method for treating waste gas containing inorganic acid is disclosed. The method includes the following steps: (a) forming a mixture of inorganic acidic gas and a nebulized alkaline solution wherein the nebulized alkaline solution can be produced continuously or periodically; (b) forcing the mixture to pass through an adsorbent bed; and (c) releasing the treated gas. An apparatus for treating the inorganic acid gas with the method illustrated above is also disclosed here. The method can regenerate poisoned adsorbents online, and save time, space and cost simultaneously.
Claims11
A regenerative de-acid apparatus for inorganic acidic gas, comprising:
- a tank having an gas inlet and an exhaust outlet;
- at least one adsorbent bed having one adsorbent, wherein the adsorbent bed is received inside the tank;
- at least one alkaline solution supply unit placed inside the tank and providing at least one alkaline solution to the at least one adsorbent bed;
- and
- at least one washing solution supply unit, positioned inside the tank and providing a solution for washing the said at least one adsorbent;
- wherein the alkaline solution supply unit is placed between the adsorbent bed and the gas inlet.
A regenerative de-acid system for inorganic acidic gas, comprising:
- a piping having plurality of branch pipe each with an opening;
- and
- a plurality of regenerative de-acid apparatuses for inorganic acidic gas, wherein each regenerative de-acid apparatus comprises:
- a tank having an gas inlet and an exhaust outlet;
- at least one adsorbent bed, which is received inside the tank and includes an adsorbent;
- at least one alkaline solution supply unit, which is received inside the tank and provides at least one alkaline solution to the at least one adsorbent bed;
- and
- at least one washing solution supply unit, which is received inside the tank and provides a solution for washing the at least one adsorbent;
- wherein the alkaline solution supply unit is positioned between the adsorbent bed and the gas inlet;
- and
- each gas inlet of the tank connects to a respective opening of the branch pipe.
