Hybrid steam discharge retracting device

Art

The utility model relates to a kind of hybrid steam discharge retracting device, and especially a kind of thermal power generation station-service pipeline that is applied to is to the hybrid steam discharge retracting device reclaiming heat energy and water during airborne release steam.

Background technology

In each Thermal Power Station therrmodynamic system, due in startup, stoppage in transit, normal operation and incident processing procedure, each valves leakage and the discharge of the working medium required by production technology in system.Working medium in therrmodynamic system all contains the water of a large amount of heat energy and high-quality in unit starting process to the later stage of stopping transport, and is generally to enter dilatation cooling in hydrophobic development unit, and its steam directly enters air by pipeline.Wherein, the exhaust of oxygen-eliminating device generally directly enters air.This method of operation causes the thermal pollution of environment on the one hand, is that a large amount of high-quality water and heat energy spill into air waste on the other hand, the make-up water percentage of power plant and coal consumption is raised, reduces the economy of full factory.In existing Steam Recovery technology, its system complex is huge, and operate cumbersome, cost is high, there are certain requirements installation site.

Utility model content

For solving the deficiency that steam directly discharges air and overcomes existing recovery technology, the steam that Thermal Power Station's production process and incident processing procedure can be discharged by the utility model, temperature condensation is on demand recycled.

The utility model is achieved through the following technical solutions: hybrid steam discharge retracting device, comprises shell, spray system, recover, air deflector.Described shell one end is connected with vapour-discharge tube, steam is by air deflector access to plant, the cooling agent condensation by mixing sprayed out with spray system, condensate water is got rid of to outer casing inner wall under inertia and Action of Gravity Field, flow to the recover being positioned at outer casing underpart, drawn by the recovery tube of recover bottom and reclaim.A small amount of incoagulable gas is discharged by the blast pipe of the shell other end.The cooling agent that spray system uses can be water and cryogenic gas, when using water, can be condensate water, closed-up water, demineralized water, optional one of recirculated water 4 systems, and can be for subsequent use each other.According to recovered temperature requirement, the spray volume of controlled cooling model agent, can obtain the water of uniform temperature.Preferred cooling agent is closed-up water, secondary blanking salt solution, condensate water, and cryogenic gas is continued to employ as one is optional, can switching for subsequent use each other between cooling agent.

Above-mentioned spray system, is made up of the spray equipment of more than a group, and is fixed on shell, and mouth spray is portion in the enclosure.Described spray equipment is single or multiple by more than one spray unit is one group, and there is the flow of Valve controlling cooling agent its front end.Described spray unit refers to nozzle and has the hole of disperse function and the jet pipe to surrounding spray, and single group spray equipment can have the combination of jet pipe and nozzle.Described spray system, coolant inlet pipeline is provided with valve, has multichannel cooling agent to originate in front of the door optional.According to difference and the congealing property of quantity of steam, the flow direction of steam progressively arranges different spray equipments, use different valve opening and closings, with accurate controlled cooling model agent, reach the object controlling water temperature, the control range of valve can be single and multiple spray unit, also can be whole one group of spray equipment.

Above-mentioned recover, is connected with shell, forms the matrix container of a upper shed with another side; The bottom of container has more than one irrigating gate to be connected with pipeline.Above-mentioned air deflector, the plate in opposite directions by more than and steam flow with the 0.1-90 degree deviation angle forms.Described plate can be plane, also can be the plate with certain curve, arranges by vapor flow direction, to guide vapor flow.Described plate, shares with recover, forms the spout that an import large outlet is little; Described spout can be regular limit, also can be other shapes such as screw type, to change the flow direction and the flow velocity of steam, cooling agent is fully mixed with steam, and gets rid of to shell under inertia and Action of Gravity Field.Described plate, can be located at below spray equipment, steam inlet place, for a change steam flow and prevent condense water fall beyond recover by steam inlet, it can be straight for meeting steam inlet face, also can be circular arc type, and the height point of circular arc is towards steam.

Compared with prior art, the utility model has advantage and beneficial effect: the utility model can be applied in the hydrophobic development unit of therrmodynamic system, the hydrophobic development unit particularly in Thermal Power Station; Energy recovery is discharged into the steam in air because of a variety of causes and approach, make full use of existence conditions in Thermal Power Station, reduces the manufacturing cost and use cost of vapour-recovery unit; Condensate water can be reclaimed by the temperature of setting, improve the utilization rate of heat energy, improve economy of power plant, reach and reduce heat energy and water resource waste, the object of cleaner production.
