Steam heat accumulator heat charging and discharging device

Technical Field

The utility model belongs to the technical field of the heat accumulator, concretely relates to steam heat accumulator charge and discharge device.

Background

Energy conservation and emission reduction, and green development are the essential way for the development of modern industry. The thermodynamic system is one of the most common power systems in the industry, and due to the change of working conditions, the load fluctuation of the thermodynamic system cannot be avoided, so that the capacity of equipment (such as a steam boiler, a feed pump, a blast induced draft fan and the like) is increased to meet the high-load thermodynamic demand, and the efficiency of the thermodynamic system is low. The steam heat accumulator can realize 'peak clipping and valley filling', balance steam load, realize reasonable configuration of equipment and improve the overall efficiency of the steam thermodynamic system; the steam heat accumulator can collect and store the waste heat generated by the production system for production or other uses, such as the recovery and utilization of converter vaporization cooling steam. Direct heat storage (i.e. the heat storage medium and the heat transfer medium are the same medium), and variable pressure (i.e. the internal pressure of the heat accumulator increases or decreases with the progress of the heat charging and discharging processes) heat accumulators are most widely used. The heat accumulator has the defects of poor heat filling effect, layered water temperature or vibration due to unreasonable design of the heat filling device, so that the heat accumulation effect is influenced, and even the safety of the pressure container is endangered. Except for the effective heat storage volume, the heat charging and discharging pressure difference and the evaporation area of the heat accumulator, the technical measure for determining the heat storage effect (heat storage amount and steam quality) of the heat accumulator is the heat charging device in the heat accumulator and guaranteeing the steam dryness.

The utility model discloses a theory of operation does:

the heat-charging steam enters the heat-charging piping 2 through the inlet 3, enters the heat-charging steam injection device 5, is redistributed to the heat storage medium (water) injected into the heat accumulator from the assembly nozzle 501, under the action of kinetic energy of the injected steam, the heat storage medium (water) in the medium diversion circulation device 6 flows along the steam injection direction, the medium in the medium diversion circulation device 6 is driven to rapidly flow from bottom to top under the action of steam injection, and the medium outside the medium diversion circulation device 6 enters the circulation cylinder from the bottom, so that the circulation of the heat storage medium is realized. In the spraying process, the heat storage medium is continuously circulated, and the sprayed steam is gradually balanced with the water temperature in the container (steam pressure, temperature reduction, medium temperature and pressure rise) to become (higher-pressure) saturated water, so that effective heat filling is realized. When the pressure of the heat release pipeline is reduced (namely the heat accumulator is needed to supplement steam), the pressure of the container space is reduced, saturated water in the heat accumulator is superheated and flashed, flash steam firstly enters the steam homogenizing device 4 from a large space (a heat accumulator evaporation space) to be flashed, fine water drops fall off, and the steam enters the inlet 3 through small holes and steel mesh for secondary expansion.
