Problems solved by technology
[0004] In nuclear waste treatment, the acid gas generated by material separation needs to be purified by acid mist using an acid absorption tower; the acid gas in nuclear waste treatment has a high temperature and high heat, and the use of neutralizing liquid will also generate heat, further The gas temperature is increased. Excessive gas temperature wastes heat on the one hand, and affects the life of the equipment on the other hand.

The invention provides an acid absorption tower for nuclear waste material separation. The acid absorption tower comprises a tower body, filler and a sprayer, wherein the filler and the sprayer are mounted in the tower body; a liquid storage tank and an air inlet are formed in the lower part in the tower body, an exhaust port is formed in the upper part in the tower body, and the liquid storage tank is used for storing a neutralizing liquid; the sprayer is used for spraying the neutralizing liquid onto the filler; the filler is arranged on the upper portion of the liquid storage tank, the filler is in a plate shape and internally provided with a flow channel, and the flow channel is used for being connected with an external cooling pipe. The flow channel is arranged in the filler, the cooling liquid is introduced into the flow channel, the cooling liquid absorbs heat in the body and conveys the heat to other places with heat requirements for use, on one hand, heat recycling is achieved, and heat waste is reduced; on the other hand, the temperature in the tower body can be prevented from being too high to accelerate corrosion and loss of equipment and affect the service life of the equipment.
Description
technical field [0001] The invention relates to the technical field of an acid absorption tower for nuclear waste treatment, in particular to an acid absorption tower for separating nuclear waste materials. Background technique [0002] The acid absorption tower, also known as the acid mist purification tower, is generally made of glass fiber reinforced plastics and used to remove acidic substances present in the gas. It can handle sulfuric acid mist, hydrochloric acid mist, chromic acid mist, nitric acid mist, phosphoric acid mist, hydrofluoric acid mist, hydrogen chloride, hydrogen fluoride, hydrogen sulfide and hydrogen cyanide in the gas. [0003] The acid absorption tower can use sodium hydroxide solution as the neutralizing liquid for acid absorption to purify the exhaust gas. The gas that needs to be purified is sent into the tower by a fan, and is absorbed by the neutralizing liquid while flowing in the tower, and the gas after absorption and purification reaches va...
