Description

Steam generating unit and include the system of this steam generating unit
Technical field
The present invention relates to steam generator technical field, specifically, relate to a kind of steam generating unit and include this steaming The system of vapour generating unit.
Background technology
Steam generator is the important component part of Steam Power Equipment, is that the heat energy utilizing fuel or other energy is water It is heated as the plant equipment of hot water or steam.
Existing steam generator generally uses boiler form, and the boiler of this kind of form is when heating, in order to reduce thin-walled The thermal stress of the commissure between pipe and thick wall shell and tube sheet is concentrated, it is necessary to heating boiler slowly, this allows for Existing boiler starts to steam output needs from cold pot and takes a substantial amount of time (at least 40 minutes), and this brings for user Great inconvenience.
The patent document of Publication No. " CN201513874U " discloses a kind of flash steam generator, although it can By the way of coil pipe heats, it is greatly promoted the speed that steam produces, but its defect is the most obvious, specifically includes that
1, its internal combustor is closely to be offseted by coil spring shape coil pipe 5 to constitute, in order to ensure to spray at combustor Flame preferably the bottom of coil device can be heated and burnt after high-temperature flue gas can be preferably to coil pipe Device top is heated, and should use with regard to the fuel at demand combustor and can possess bigger specific flame spread when burning The high-grade fuel at angle, this is just greatly improved operating cost;It addition, coil spring shape coil pipe 5 closely offsets, it is being heated Time can expand, this has just buried serious potential safety hazard;
2, the inside of its heat exchanger 1 is whole connection, and the most operationally, heat exchanger 1 is whole is a high pressure coil pipe, And the volume of heat exchanger 1 is the biggest, the internal hydraulic pressure upper limit that can reach of heat exchanger 1 is the biggest and pressure is also more difficult to carry out fast The regulation of speed, this just considerably increases the risk of heat exchanger 1 blast.
Summary of the invention
The invention provides a kind of steam generating unit, it can preferably overcome explosive the lacking of existing steam generator Fall into.
According to the steam generating unit of the present invention, it includes that what the two ends being located in a closed housing body were all in communication with the outside adds The passage of heat, adds the passage of heat and is sequentially provided with first in import to the direction of outlet by hot cell, second single by hot cell and preheating Unit;First by hot cell, second by being equipped with water stream channel in hot cell and preheating unit, preheating unit, first by hot cell Be sequentially communicated by the internal water flow passages of hot cell with second, preheating unit and first by between hot cell the most successively pipeline connect have Pressure-regulating valve and check-valves.
In the steam generating unit of the present invention, check-valves can preferably by preheating unit and first by hot cell, second Being cut off by hot cell, this makes in the case of the overall operation constancy of volume, and only first is heated list by hot cell and second High pressure can be there is in the inside of unit;Reduction due to high pressure section volume so that first by hot cell and second by can in hot cell The upper pressure limit reached also can reduce accordingly, and first also is able to comparatively fast by the pressure at hot cell by hot cell and second Be adjusted so that the probability considerably increasing safety in utilization, reducing blast.It addition, the setting of pressure-regulating valve makes Pressure of supply water at preheating unit can preferably be adjusted so that preferably to reduce and cause first to be subject to because of the fluctuation of pressure of supply water Hot cell and second is by the force value in hot cell extremely.
Present invention also offers a kind of steam generating system, it includes above-mentioned steam generating unit.Wherein, preheating unit Water stream channel and a water system pipeline connect, second by water stream channel and the Steam heating systems pipeline company of hot cell Connect.
As preferably, preheating unit and first is provided with water pump by between hot cell or between water system and preheating unit.Water pump Preferably liquid medium can be pumped into first by hot cell and second by hot cell, and medium can be subject to first Hot cell and second is by forced flow in hot cell such that it is able to is prevented effectively from thermal stress and concentrates so that first by hot cell and Second will not be damaged so that destroying because of temperature abrupt change by hot cell.
