Description
Technical Field
The utility model relates to a useless cobalt molybdenum hydrogenation catalyst retrieves and recycles technical field, specifically is a useless cobalt molybdenum hydrogenation catalyst retrieves and recycles pickling device.
Background
It is well known that catalysts are at the heart of the chemical industry and that greater than 90% of industrial processes use catalysts. Among them, the hydrotreating catalyst is an important supported metal catalyst, which is widely used in the oil refining industry, with annual output of 15-17 ten thousand tons and average annual growth rate of about 5.6%. The activity of the hydrogenation catalyst is reduced in the using process and finally the hydrogenation catalyst is deactivated, but the amount of the catalyst capable of recovering the activity by a regeneration technology is less than 50 percent of the total amount of the deactivated catalyst, and the nonrenewable catalyst can cause a series of environmental hazards to the surrounding soil, water and atmosphere if being randomly stacked without being treated. The technology for recovering, treating and utilizing the spent hydrogenation catalyst at home and abroad mainly comprises landfill, cement raw material and metal recovery. The landfill occupies land and has high cost, the added value of the prepared cement raw material is low, secondary pollution is easy to generate, and the waste catalyst is used as the raw material to carry out the integral recycling of all metal elements, so that the treatment cost can be reduced, the environmental hazard is reduced, and the requirement of the reduction, reutilization and resource recycling for the development of the circular economy is met.
In the recovery, an acid leaching device is required, and acid leaching (acid leaching) refers to a mineral leaching process using an aqueous solution of an inorganic acid as a leaching agent. It is one of the most commonly used leaching methods in chemical ore dressing. Sulfuric acid, hydrochloric acid, nitric acid, sulfurous acid, hydrofluoric acid, aqua regia and the like can be used as the leaching agent, wherein the most widely used is sulfuric acid. The dilute sulfuric acid is weak oxidizing acid, can be used for treating mineral raw materials containing a large amount of reducing components (such as organic matters, sulfides, ferrous oxide and the like), is low in cost and easy to obtain, the corrosion prevention problem of equipment is easy to solve, the sulfuric acid solution has a high boiling point, and a high leaching temperature can be adopted under normal pressure. Hot concentrated sulfuric acid is a strong oxidant, and can convert most of sulfide minerals into corresponding sulfates. The reaction capability of the hydrochloric acid is stronger than that of the sulfuric acid, and the oxysalt minerals which cannot be leached by the sulfuric acid can be leached out, but the hydrochloric acid has higher price, is volatile, has poorer labor conditions, and has higher corrosion resistance requirement than the sulfuric acid. Nitric acid is a strong oxidizing acid, has high price and high corrosion resistance requirement of equipment, and is not used as a leaching agent and is often used as an oxidizing agent.
Because acid leaching requires a highly corrosive acid leaching agent, and the corrosivity of the acid leaching agent can seriously damage metals, most of the existing acid leaching devices adopt corrosion-resistant metal materials, but the acid leaching devices need to be heated when in acid leaching, the higher the temperature is, the higher the corrosivity is, the more corrosion-resistant metals are needed, as is well known, the higher the price of the more corrosion-resistant metals is, the higher the production cost is, the higher the price is, and in order to ensure that the acid leaching devices have certain heat preservation performance so as to reduce the loss of heat, some acid leaching devices are also provided with heat preservation layers, although the heat preservation performance is increased, the acid leaching devices still have certain temperature after discharging liquid, and the temperature can be reduced for a long time, so that the liquid remained in the acid leaching devices and some corrosive gases volatilized can continuously corrode the acid leaching devices, although the corrosiveness and the corrosiveness during acid leaching are weakened, the acid leaching device still has certain corrosiveness, and the service life of the acid leaching device is shortened.
