The invention relates to an asphalt pre-moulding energy-saving environmental-protection cooling technology, and a device. The device comprises an asphalt storage tank, an asphalt transfer pump, an asphalt falling film vaporization cooler, an inner ring steam pipe, an inner ring water pipe, and a liquidometer; hot asphalt in the asphalt storage tank is pumped into a tube pass of the lower part of the asphalt falling film vaporization cooler using the asphalt transfer pump for cooling with hot water; hot water is vaporized into steam after absorption of heat energy of hot asphalt; the steam is introduced into a shell pass of the upper part of the asphalt falling film vaporization cooler through the inner ring steam pipe for heat exchange with circulating cooling water, is condensated and cooled into hot water, and flows into a shell pass of the lower part of the asphalt falling film vaporization cooler through the inner ring water pipe, so that self circulation is formed; hot asphalt inthe tube pass of the lower part of the asphalt falling film vaporization cooler is cooled to a temperature of about 30 DEG C higher than the asphalt softening point with hot water so as to obtain lowtemperature asphalt, discharging is realized under nitrogen pressure, and deasphalting moulding is realized. The beneficial effects are that: equipment number is low; occupied space area is large; investment is low; and environment protection effect is excellent.
Description
technical field [0001] The invention relates to an asphalt cooling forming process in the technical field of coal coking, in particular to an energy-saving and environment-friendly cooling process and device before asphalt forming. Background technique [0002] With the rapid development of the coal coking industry, the asphalt processing industry has been paid more and more attention by people, especially in recent years, the price of asphalt has risen unprecedentedly, and the asphalt processing industry is also booming. As an important process in the asphalt processing industry - asphalt cooling and forming process, it also needs to constantly introduce new ones. Chinese patent 201810081534.X discloses "a cooling process and system before asphalt molding, including a falling film cooler, a steam air cooler, a condensate tank, and a condensate pump; The liquid asphalt conveying pipeline is connected, and the outlet of the lower tube side is connected with the asphalt formi...
