Caustic soda recycling device for chemical machinery

Abstract

The invention discloses a caustic soda recycling device for chemical machinery. The caustic soda recycling device comprises a first tank body and a second tank body, wherein a feed pipe is arranged inside the first tank body; another feed pipe is fixed above the feed pipe; an auxiliary material pipe penetrates through the inner wall of the left side of the first tank body; a heating ring is arranged at the bottom of the interior of the first tank body, and a through pipe penetrates through the lower side of the right wall of the first tank body; a valve is arranged on the outer side of the through pipe; a partition plate is fixed on the inner wall of the second tank body; and the second tank body is positioned on the right side of the through pipe. According to the caustic soda recycling device for chemical machinery, due to the arrangement of the feed pipe, raw materials containing caustic soda can be smoothly added into the first tank body, and the materials are uniformly dispersed due to an inclined plate and a semicircular mesh arranged in the feed pipe, so that the materials are scattered; chemical reaction additives are introduced into the auxiliary material pipe and are usedfor reducing and purifying the caustic soda; and due to the arrangement of a first ring pipe, a second ring pipe and a third ring pipe, the addition range area of the additives is enlarged.

Description

technical field [0001] The invention relates to the technical field of caustic soda recycling and processing devices, in particular to a caustic soda recycling and processing device for chemical machinery. Background technique [0002] Sodium hydroxide, the chemical formula is NaOH, commonly known as caustic soda, caustic soda, and caustic soda, is a strong corrosive alkali, generally in the form of flakes or blocks, easily soluble in water (heat release when dissolved in water) and It forms an alkaline solution, and it is also deliquescent, and it is easy to absorb water vapor (deliquescence) and carbon dioxide (deterioration) in the air. It can be checked for deterioration by adding hydrochloric acid. In modern industrial production, the amount of caustic soda used is very large, but the used Not all of the caustic soda is used in production, which leads to the waste of caustic soda. If the caustic soda is not treated, it will not only cause waste of enterprise costs, but ...

Problems solved by technology

[0004] The object of the present invention is to provide a kind of caustic soda recovery processing device for chemical machinery, to solve the problem that the modern caustic soda recovery processing device proposed in the above background technology is not high in the treatment level of caustic soda purity, and the caustic soda recovery processing device equipped in general factories They are all basic treatment devices, that is, the reduction purity of caustic soda is not high, and at the same time, caustic soda is prone to chemical reaction and deterioration when it encounters air, which leads to a certain degree of irrationality in the recovery process of caustic soda, and caustic soda is in the process of purification and recovery. , especially when taking it, it is necessary to conduct an instant, fast and convenient purity test, and this aspect is also a relatively lacking problem at present
