Description
Technical field
The invention belongs to textile dyeing and finishing technical field, and in particular to a kind of for the automatically controlled hydrophobic of steam baking tube equipment of printing and dyeing
Device.
Background technology
At present, printing and dyeing enterprise carries out drying belt water fabric using steam baking tube in a large number, and the condensed water of steam baking tube and sky
The incoagulable gas such as gas can all affect heat exchanger effectiveness, accordingly, it would be desirable to discharge it the thermal effect that could improve gas utilization unit in time
Rate, so as to steam saving, reduces fuel consumption.For this purpose, must be equipped with Automatic steam trap Trap using steam-heated equipment（Also known as
Steam trap）, the condensate of continuous generation is automatically drained out, and prevents steam from leaking.
In the prior art, the steam baking tube of printing and dyeing enterprise discharges condensate using two kinds of different modes：1. by using
Automatic steam trap Trap is discharged, but steam in drain valve and incoagulable gas can not be discharged by Automatic steam trap Trap well in time
When, easily form vapour (gas) lock phenomenon；2. the presence of the electrical control steam drain valve with temperature detection cannot arrange temperature return difference, cause
Valve body is frequently opened, is closed near the temperature set-point so that valve body is fragile and service life is short.
So-called vapour (gas) is locked, and is referred to as vapor lock by what steam caused, is referred to as air by what the incoagulable gas such as air caused
Lock.The mechanism of both phenomenons is similar to, and is to be introduced into drain valve due to steam or incoagulable gas before condensate, makes to dredge
Water valve cuts out so that steam baking tube is locked in steam baking tube by vapour (gas) due to the condensate that heat exchange is produced, it is impossible to logical
Cross drain valve discharge.Cause, full of condensate in steam baking tube, so easily to form water hammer, aggravate tube wall, valve and connector
Abrasion, increases maintenance cost and downtime；And in drying cylinder, water accumulation amount causes drying cylinder deadweight to increase, and during high-speed rotation, produces
Raw potential safety hazard；Condensate row do not go out, and affects drying cylinder heat transfer effect, increased drying time, and steam economy is big, energy profit
Low with rate, operation costs increase, impact production capacity lifting.
Content of the invention
It is an object of the invention to provide a kind of formation that can be prevented effectively from vapour lock, and the steam baking tube of efficient energy-saving is automatically controlled

In technique scheme, also include water conductivity transmitter, the water conductivity transmitter is located at drain pipe
On pipeline, and water conductivity transmitter is electrically connected with the controller.
In technique scheme, the water conductivity transmitter is located at the temperature transmitter on the pipeline of drain pipe and control
Between valve processed.
In technique scheme, the controller is digitial controller, or industrial computer.
In technique scheme, when the control valve is electromagnetic valve, the control valve is directly or indirectly electric with controller
Connection.
In technique scheme, when the control valve is pneumatic operated valve, the control valve is electrically connected indirectly with controller.
The good effect that the present invention has is：After the automatically controlled steam trap connection of the steam baking tube of the present invention, due to this
Bright also include temperature transmitter, control valve, drain pipe and controller；The drain pipe is connected with the drain port of steam swivel joint
Logical, and the pipeline of drain pipe is provided with temperature transmitter and control valve, the temperature transmitter is electrically connected with the controller, the control
Valve processed is directly or indirectly electrically connected with controller；According to the data of temperature transmitter detection and the data of controller setting
Control return difference discharges solution deaeration with being more accurately controlled the incoagulable gas such as air and condensate（Gas）Lock；Avoid existing product
Cannot design temperature control point control return difference, valve body frequent movement, the drawbacks of affect its working life；The controller according to
The data that temperature transmitter real-time detection is arrived, the analysis to saturated-steam temperature and saturated vapour pressure, it becomes possible to control in time
The break-make of control valve, solves deaeration lock in time, and accurately hydrophobic, Measure Precision is higher, is greatly enhanced hydrophobic efficiency, while carrying significantly
High steam utilization so as to efficient energy-saving.
