Abstract
The utility model provides a smoke pre-cooling device through spraying, comprising at least one nozzle arranged in a bypass flue. The nozzle is connected to a water-supplying pipe for spraying which is provided with an automatic control valve. A signal input end of the automatic control valve is respectively connected to a signal output end of a baffle door for opening and closing a motor and a signal output end of a temperature measuring device arranged in a cleaning flue. The baffle door for opening and closing a motor is connected to a baffle door of the bypass flue at the inlet of the bypass flue. The utility model can efficiently decrease the temperature of the smoke, with simple structure, stable working performance, and wide range of applicable temperature and smoke flow.
Description
Technical field
The utility model provides a kind of flue gas spray precooling treatment device, belongs to chimney anticorrosion flue gas processing technology field.
Background technology
The chimney of wet method fume desulfurizing system connects clean flue and bypass flue respectively, when installing, it need take anti-corrosion measure usually, and the flue gas in the chimney is because the operation of bypass operation and accident condition often is in higher temperature, and high-temperature flue gas easily makes the chimney anticorrosion layer stand high temperature and very fast aging or destroy.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of effective flue gas cool-down spray equipment is provided.
In order to achieve the above object, the technical solution of the utility model provides a kind of flue gas spray precooling treatment device, it is characterized in that, comprise at least one nozzle of being located in the bypass flue, nozzle connects the spray feed pipe, the spray feed pipe is provided with autocontrol valve, the signal input part of autocontrol valve connects baffle door respectively and opens and closes the signal output part of motor and the signal output part of being located at the temperature measuring equipment in the clean flue, and baffle door opens and closes the bypass damper door that motor is connected at the bypass chimney intake.
Spraying cooling device of the present utility model has mainly adopted the design of shower water cooling, and adopts coordinated control system, thereby makes the quick and stable performance of whole system cooling.When the by-pass damper door is opened or the clean gas baffle of desulphurization system behind the door temperature exceed 120-125 ℃ of setting value, or when satisfying above two conditions simultaneously, the by-pass valve control that spray is responsible for will be opened, nozzle begins spraying cooling work; After the damper door is closed fully or the clean gas baffle of desulphurization system behind the door temperature be lower than setting value, or when satisfying above two conditions simultaneously, the by-pass valve control that shower is responsible for is closed, nozzle stops spray.Nozzle can begin spray in order to guarantee to spray valve open, must guarantee certain pressure for a long time with the spray system water pipe connecting.
The utility model can effectively reduce flue-gas temperature, have simple and reasonable, stable work in work, Applicable temperature and the big advantage of flue gas flow scope.
Description of drawings
Fig. 1 is a kind of flue gas spray precooling treatment apparatus structure schematic diagram.
The specific embodiment
Specify the utility model below in conjunction with embodiment.
Embodiment 1
As shown in Figure 1, be a kind of flue gas spray precooling treatment apparatus structure schematic diagram, described flue gas spray precooling treatment device opens and closes motor 4, nozzle 5, bypass flue 6 and spray feed pipe 7 by bypass damper door 2, autocontrol valve 3, baffle door and forms.
The bypass flue 6 that chimney 9 connects clean flue 8 and is located at bypass.Be located at least one nozzle 5 in the bypass flue 6, nozzle 5 connects spray feed pipe 7, spray feed pipe 7 is provided with autocontrol valve 3, the signal input part of autocontrol valve 3 connects baffle door respectively and opens and closes the signal output part of motor 4 and the signal output part of being located at the temperature measuring equipment in the clean flue 8, and baffle door opens and closes the bypass damper door 2 that motor 4 is connected at 6 imports of bypass flue.Spray system adopts metal pipe line, and the spray feed pipe 7 of flue inside adopts corrosion resistant stainless steel to make.
When baffle door switch 4 is opened or the clean gas baffle of desulphurization system behind the door temperature exceed setting value, or when satisfying above two conditions simultaneously, the autocontrol valve 3 that spray is responsible for will be opened, nozzle 5 begins the spraying cooling work; After the damper door is closed fully or the clean gas baffle of desulphurization system behind the door temperature be lower than setting value, or when satisfying above two conditions simultaneously, the autocontrol valve 3 of shower is closed, nozzle 5 stops spray.
