Problems solved by technology

Although this method can meet the requirements of transportation or users for the use of asphalt temperature, because the liquid asphalt is in a high temperature state for a long time, it is easy to oxidize or volatilize in large quantities, which will reduce its quality characteristics

Embodiment Construction

[0015] Embodiments of the present invention: The present invention is mainly equipped with an asphalt storage tank (1), a heat conduction oil pipe (2), a heater (3), an asphalt circulation pump (4), an asphalt delivery pump (5), and an asphalt valve (6). The heater (3) is mainly composed of heat-conducting oil tube bundles, and high-temperature heat-conducting oil can be introduced into the heat-conducting oil tubes to heat the asphalt. Electric heating is usually not used to avoid coking of the asphalt. The heater (3) is movably installed in the asphalt storage tank (1), and can be drawn out for cleaning when needed. The asphalt discharge port (7) to the user is generally set at the corresponding position of the lower end of the heater, so as to meet the requirements of the transportation or the user for the asphalt temperature. The heat-conducting oil pipes (2) usually contain 2-4, and are evenly distributed on the inner wall of the asphalt storage tank (1), so as to meet th...

Abstract

The invention discloses a low-temperature storage technique of liquid tar, which comprises the following parts: tar storage groove (1), heat conductivity oil pipe (2), heater (3), tar circulating pump (4), tar transmission pump (5) and tar valve (6), wherein the heater is set on the bottom of tar storage groove to heat bottom tar, which keeps most of tar at low-temperature state; several heat conductivity oil pipes are set in the tar storage groove from up to down, which drains water outsides and avoids overflow accident of tar. The invention can stew liquid tar for a long time, which prevents tar from oxygenizing and volatilizing effectively.

Description

Technical field: [0001] The invention relates to a low-temperature storage device for liquid asphalt, in particular to a device for storing liquid asphalt for a long time. Background technique: [0002] Liquid asphalt often needs to be stored in asphalt storage tanks for a period of time. When stored under high temperature conditions, it will react with air in the atmosphere to oxidize or volatilize a large amount of asphalt and reduce its quality characteristics. In order to meet the requirements of transportation or users for asphalt temperature, heat conduction oil coils are usually arranged around the asphalt storage tank from top to bottom, and the mechanical stirring device installed on the top of the storage tank is used to increase the heat transfer efficiency. Although such a method can meet the requirements of transportation or users for the use of asphalt temperature, because the liquid asphalt is in a high temperature state for a long time, it is easy to oxidize ...
