A multi-stage heating heat transfer oil circulation system and method thereof

Abstract

The invention discloses a multi-stage heating heat conduction oil circulating system. The multi-stage heating heat conduction oil circulating system comprises a heat conduction oil heating unit, a cold heat conduction oil inlet pipe, a heat using unit, a hot heat conduction oil outlet pipe, a first oil-gas separation device and a circulating pump. The cold heat conduction oil outlet end of the heat using unit is connected with the oil inlet end of the cold heat conduction oil inlet pipe. The oil outlet end of the cold heat conduction oil inlet pipe is connected with the cold heat conduction oil inlet end of the heat conduction oil heating unit. The hot heat conduction oil outlet end of the heat conduction oil heating unit is connected with the oil inlet end of the hot heat conduction oil outlet pipe. The oil outlet end of the hot heat conduction oil outlet pipe is connected with the hot oil inlet end of the heat using unit. The multi-stage heating heat conduction oil circulating systemis simple in structure; and a pre-combustion chamber structure is arranged in a furnace core and matched with an external main combustion chamber structure to achieve sextuple heating of incoming heat conduction oil, so that the heating efficiency of a heating pipe is effectively improved.

Description

technical field [0001] The invention belongs to the field of heat-conducting oil heating, and in particular relates to a multi-stage heating heat-conducting oil circulation system and a method thereof. Background technique [0002] The heat-conducting oil boiler uses heat-conducting oil as the medium, and uses the hot oil circulating oil pump to force the medium to circulate in liquid phase, transfer the heat energy to the heat-consuming equipment and then return to the heating furnace for reheating, and deliver the heat energy to the heat-consuming equipment before returning to the heating furnace for reheating , with high working temperature under low pressure, and high-precision control of medium operation; however, the existing boiler body is mostly a single combustion chamber furnace body, in which the flame often flows from One end is sprayed to the other end, the flame near the flame nozzle has a high temperature due to sufficient oxygen and fuel, and the flame temper...

[0002] The heat-conducting oil boiler uses heat-conducting oil as the medium, and uses the hot oil circulating oil pump to force the medium to circulate in liquid phase, transfer the heat energy to the heat-consuming equipment and then return to the heating furnace for reheating, and deliver the heat energy to the heat-consuming equipment before returning to the heating furnace for reheating , with high working temperature under low pressure, and high-precision control of medium operation; however, the existing boiler body is mostly a single combustion chamber furnace body, in which the flame often flows from One end is sprayed to the other end, the flame near the flame nozzle has a high temperature due to sufficient oxygen and fuel, and the flame temperature far away from the flame nozzle is relatively low, and the unevenness of the front heat and the rear cooling is obvious, and it is a single combustion chamber, which is easy to burn. Insufficient combustion is a waste of resources. At the same time, due to the existing ordinary cylindrical combustion chamber, the heating efficiency of the heating tube is not high, and a lot of energy escapes through the flue gas. If it is not separated in time, it will cause uneven local heating of the heating pipeline and the risk of damage to the equipment
