Slag evaporating system for extracting turpentine oil from molten slag

Abstract

The invention discloses a slag evaporating system for extracting turpentine oil from molten slag. The system comprises a slag evaporating machine, a cooler and a recovering tank which are communicated in sequence, wherein the slag evaporating machine comprises a first slag evaporating tank (11) and a second slag evaporating tank (12) which are arranged crossly; communication pipes (13) and (14) are arranged to communicate the first slag evaporating tank (11) and the second slag evaporating tank (12); the lower end of the first slag evaporating tank (11) is provided with a slag inlet (15); the communication pipe (14) is provided with a slag outlet; each slag evaporating tank is coated with a tank sleeve; an enclosed steam cavity is formed between the tank sleeve and the outer wall of each slag evaporating tank; the lower section and the upper section of the tank sleeve are provided with a water discharging hole and a steam inlet hole respectively; a shaft with a spiral impeller is arranged in each slag evaporating tank; and the tank wall is provided with a turpentine oil outlet. The system has the advantages of skillful and reasonable structural design, high specificity, special design for extracting turpentine oil from molten slag, full evaporation and boiling of turpentine slag, high recovering rate of turpentine oil and the like. The molten slag is recovered, so that waste is changed into treasure, the resource is saved, the enterprise cost is lowered, and the economic benefit of an enterprise is increased.

Description

technical field [0001] The invention belongs to the field of industrial technology, and in particular relates to a slag steaming device used in the processing of rosin. Background technique [0002] Rosin can be processed into rosin and turpentine. Rosin has the properties of moisture resistance, anticorrosion, insulation, emulsification, and adhesion. It is an important chemical raw material and is widely used in papermaking, paint, medicine, printing and dyeing, coatings, textiles and other industries; It is a volatile oil widely used in industries such as paint and tanning. It is used as an antidote, skin stimulant in medicine, and can also be used to make spices. In the process of turpentine processing, first put the rosin into the melting pot to melt, the turpentine evaporated during the melting process is recovered through the condenser, and the melted fat liquid enters the high-level pot and the clarification pot for the next step of extraction and recovery, after bei...

AI Technical Summary

Problems solved by technology

In fact, there is still a lot of turpentine stuck in these pine slags, which are only melted in one step in a melting pot, and it is not completely evaporated. The source of turpentine as a raw material is very limited, and the pine slag is simply discarded, which is not only a waste of resources , also cause environmental pollution
