Oil-gas separation device and method of hot oil circulation system

Abstract

The invention discloses an oil-gas separation device of a hot oil circulation system. The oil-gas separation device comprises an oil-gas separation device body. The oil-gas separation device body comprises an oil-gas separation box. A first division plate is included in the oil-gas separation box and divides an inner cavity of the oil-gas separation box into a left cavity and a right cavity. The lower end of the first division plate is connected with the box bottom of the oil-gas separation box. A liquid overflow channel is arranged between the upper end of the first division plate and the boxtop of the oil-gas separation box. When liquid in the left cavity reaches the upper end of the first division plate, the liquid can overflow into the right cavity. A second division plate is furtherincluded and obliquely divides the left cavity into an oil inlet cavity and a transition cavity. The oil-gas separation device is simple in structure, an overflow type first division plate semi-division structure is adopted, the effect of bubble overflow is achieved, and the function of stopping precipitate is also achieved.

Description

technical field [0001] The invention belongs to the field of boilers, and in particular relates to an oil-gas separation device of a thermal oil circulation system and a method thereof. Background technique [0002] The gas-fired hot 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, and then transfers the heat energy to the heat-consuming equipment and then returns to the heating furnace for reheating. , Air bubbles are easy to form in the pipeline. If the bubbles are not overflowed in time, the pressure in the pipeline will increase and the equipment will be damaged. A large amount of heat is not utilized in the flue gas discharged from the boiler. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides an oil-gas separation device and method for a thermal oil circulation system. [0004]...
