Description
Technical field
It is especially a kind of to be used for flue gas purification system waste heat the present invention relates to a kind of flue gas purification system valve controling circuit
The valve controling circuit of recovery.
Background technology
Equipment for dyeing and finishing is for example：Forming machine, air compressor machine, tank steaming machine etc., are all by oil heating, steam heating, gas heating
Or a kind of in the mode such as electrical heating natural air is heated after the drying room of equipment for dyeing and finishing is sent into by blower fan, then inside drying room
The gas of heating is sprayed onto fabric face, such iterative cycles by tuyere.And the flue gas that equipment is produced then typically enters through heat exchanger
Row waste heat recovery, current residual neat recovering system is that waste heat directly is used for into the water such as bathroom, but due to different in production process
The waste heat supply temperature of equipment source differs, and waste heat supply temperature of the same equipment among one day is also more big changes, and waste heat is made into single
, often there is the water temperature after waste-heat and change greatly so that there is inconvenience when using in the recycling of one purposes.
The content of the invention
The purpose of the present invention is to overcome the deficiencies in the prior art electric there is provided a kind of flue gas purification system Valve controlling
The work on road, rationally control water pump and valve body, abundant recovered flue gas cleaning system waste heat.
The technical scheme provided according to the present invention, the flue gas purification system valve controling circuit, it is characterized in that：Including with
The temperature controller T and relay KA1 of power supply connection, the coil of temperature controller T the first contact portion time relay sj 2, temperature controller T
The second contact difference Connection Time relay SJ1 coil and relay KA2 coil；The time relay sj 1 and when
Between relay SJ2 normally opened contact be connected in parallel, the normally opened contact two ends difference of time relay sj 1 and time relay sj 2
Connect relay KM1 and relay KA1 contact；The normally opened contact of the relay KA2 and time relay sj 1 and time after
Electrical equipment SJ2 normally opened contact is in parallel, and relay KA2 normally opened contact two ends connect relay KA1 contact and relay respectively
Y。
The coil two ends of the relay KA1 connect dc source respectively.
Flue gas purification system valve controling circuit of the present invention, can rationally control the work of water pump and valve body, fully
Recovered flue gas cleaning system waste heat.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Embodiment
With reference to specific accompanying drawing, the invention will be further described.
As shown in Figure 1：The flue gas purification system valve controling circuit includes temperature controller T, relay KA1, relay
KA2, time relay sj 1, time relay sj 2, relay KM1, relay Y etc..
As shown in figure 1, the present invention includes the temperature controller T and relay KA1 being connected with power supply, temperature controller T the first contact
Distinguish the coil and relay of Connection Time relay SJ1 in Connection Time relay SJ2 coil, temperature controller T the second contact
KA2 coil；The normally opened contact of the time relay sj 1 and time relay sj 2 is connected in parallel, the He of time relay sj 1
The normally opened contact two ends of time relay sj 2 connect relay KM1 and relay KA1 contact respectively；The relay KA2's
Normally opened contact is in parallel with the normally opened contact of time relay sj 1 and time relay sj 2, relay KA2 normally opened contact two ends
Relay KA1 contact and relay Y is connected respectively.
The coil two ends of the relay KA1 connect 24V dc sources respectively, for receiving flue gas purification system operation
Signal.
The operation principle of the present invention：When flue gas purification system is run, relay KA1 coil receives signal energization,
The relay KA1 closing of contact, so that temperature controller T is operated.
When the temperature that temperature controller T probe is detected is less than a certain numerical value t, temperature controller T first closing of contact, time
After relay SJ2 coil electricity, the contact timing closing of time relay sj 2, the closing of contact of time relay sj 2, after
Electrical equipment KM1 energization work, relay KM1 is used to control pump working.
When the temperature that temperature controller T probe is detected is higher than a certain numerical value t, temperature controller T second closing of contact, time
Relay SJ1 and relay KA2 coil electricity, the relay KA2 closing of contact, the contact delay of time relay sj 1 are closed
Close, relay Y power control electromagnetic valve works, relay KM1 control water pump delay workings.
