Solid-liquid separation device and method for producing Hopcalite

Abstract

The invention discloses a solid-liquid separation device and a method for producing Hopcalite, relating to the field of solid-liquid separation devices of chemical reaction products and catalyst preparation. The device comprises a sealed tank, wherein a feed opening is formed in the top of the sealed tank, a filtering layer is arranged at the lower middle part in the sealed tank, a rotating shaft is arranged on the outer side of the sealed tank, and the rotating shaft is a hollow shaft and is connected with a power overturning device; the upper side of the filtering layer in the sealed tank is connected with an air compressor through the rotating shaft and an air compression pipeline; a drain valve and a drain pipeline are arranged at the bottom of the sealed tank, the other end of the drain pipeline is connected with a gas-liquid separator, the top of the gas-liquid separator is connected with a vacuum pump through a vacuum pipeline, and a liquid outlet is formed in the bottom of the gas-liquid separator; the air compression pipeline is connected with the drain pipeline through a pipeline, and valves, liquid inlet valves and air compression valves are respectively arranged on the pipeline, the drain pipeline and the air compression pipeline. The device is good in solid-liquid separation effect and is high in production efficiency; when the device is used for producing Hopcalite, the cost is low, the production cycle is short, potassium sulfate and sodium sulfate can be respectively recovered, and thus the potassium sulfate and the sodium sulfate can be recycled.

Description

technical field [0001] The invention relates to the technical field of preparation of a chemical reactant solid-liquid separation device and a catalyst. Background technique [0002] Hopcalate agent is a catalyst product for filtering carbon monoxide, its main component is a mixture of manganese oxide and copper oxide. Produced by a chemical reaction, accompanied by sulfate ions such as sodium sulfate and potassium sulfate, it is a substance harmful to hopcalate products, and it is necessary to remove sulfate ions from hopcalate to produce qualified Hopcalla agent. [0003] Hopcalate agent is a kind of solid, insoluble in water, and sulfate ion is easy to dissolve in water, and the production process device of traditional hopcalate agent is as figure 2 Shown, comprise the following steps: 1, water is added reactor, add the vitriol oil, as the medium solution of reaction; 2, add manganese sulfate in reactor, dissolve; Add potassium permanganate reaction, generate manganese ...

AI Technical Summary

Problems solved by technology

The production technology of traditional hopcalate agent has the following disadvantages: 1, the sulfate ion discharged is the mixture of potassium sulfate and sodium sulfate, which cannot be recycled; 2, the production cost is high, and the usage amount of soda ash is large (generating basic carbonic acid The copper process will use a large amount of soda ash to neutralize dilute sulfuric acid and convert it into sodium sulfate); 3. The production efficiency is low, and it usually takes 8 days to complete
