Description
Technical field
The utility model relates to energy-saving combustion system device technique field, particularly relates to a kind of BH stove energy-saving combustion control system.
Background technology
PCB, as the carrier of electronic product, moves ahead at a quick pace along with the develop rapidly of electronics and information industry.Data show, the PCB output value output of China occupies first place in the world position.And electronic-grade glass fiber cloth is as one of PCB substrate, also in development at full speed, but want to make industry value chain, environment protection treating, energy-saving and emission-reduction become the problem that current whole industry is badly in need of solving.
Simultaneously because energy resource is more and more nervous, its price grows to even greater heights, and energy-conservation cry is more and more higher.In the production of electronic-grade glass fiber cloth, postprocessing working procedures is the rich and influential family of energy resource consumption, for the consumption of natural gas, again based on batch destarch of hot destarch process.BH desizing furnace, in electronic-grade glass fiber cloth destarch production process, is in one " intensification--constant temperature-intensification-constant temperature " process.Under different temperatures different conditions, body of heater is different to heat demand, is therefore also different to the demand and supply of natural gas and oxygen.Existing BH stove combustion control system, its combustion air is constant under fan action passing in burner, and natural gas intake is directly controlled by in-furnace temperature and furnace pressure, and this process controls inaccuracy to natural gas infeed amount, can cause a large amount of wastes.
Utility model content
The purpose of this utility model is to provide a kind of BH stove energy-saving combustion control system, which solves the technical problem of the combustion-supporting and constant energy waste caused of throughput of current BH stove.
For achieving the above object, the technical scheme that the utility model proposes is:
A kind of BH stove energy-saving combustion control system of the present utility model, it comprises: a PLC, temperature sensor, and described temperature sensor sends temperature information to described PLC; One air gas ratio adjusting valve, described air gas ratio adjusting valve is controlled by PLC; One combustor, passes into natural gas in described combustor, and the input quantity of natural gas is controlled by described air gas ratio adjusting valve; One ratiomotor, described ratiomotor is controlled by PLC; One combustion fan, the throughput of described combustion fan is controlled by described ratiomotor, and one for closing down the stop valve of BH stove.
Preferably, a circulating fan for driving BH gas stream in the stove to circulate also is comprised.
Compared with prior art; a kind of BH stove energy-saving combustion control system of the present utility model; by PLC, intelligence conveying is carried out to combustion-supporting gas and the amount of natural gas passing into burning; improve efficiency of combustion; furnace temperature is more constant; the discharge of decreasing pollution thing, effectively protects environment, decreases waste simultaneously.
Accompanying drawing explanation
Fig. 1 is the structured flowchart of the utility model BH stove energy-saving combustion control system.
Detailed description of the invention
Below with reference to accompanying drawing, elaboration is further given to the utility model.
Refer to Fig. 1, in the present embodiment, a kind of BH stove energy-saving combustion control system of the present utility model, it comprises: a PLC 1, temperature sensor 2, air gas ratio adjusting valve 3, combustor 4, ratiomotor 5, combustion fan 6 and a stop valve 7.
Wherein, temperature information is sent to described PLC 1 by described temperature sensor 2; Described air gas ratio adjusting valve 3 is controlled by PLC 1, described PLC according to the data of internal preset, Real-Time Monitoring BH in-furnace temperature value, and in time change the intake of natural gas by adjustment air gas ratio adjusting valve 3.Combustor 4, passes into natural gas in described combustor 4, and the input quantity of natural gas is controlled by described air gas ratio adjusting valve 3, and namely described air gas ratio adjusting valve 3 is installed in natural-gas transfer pipeline, controls the size of the input of natural gas.One ratiomotor 5, described ratiomotor 5 is controlled by PLC 1; Combustion fan 6, the throughput of described combustion fan 6 is controlled by described ratiomotor 5, in order to realize the efficient combustion of natural gas, improve its utilization rate, therefore, according to the amount passing into natural gas as far as possible, adapt to change the amount passing into combustion-supporting gas, namely described ratiomotor 5 designs for this reason.And one for closing down the stop valve 7 of BH stove.This stop valve 7, for when closing down BH stove, cuts off all breather lines.Wherein, described stop valve 7 can adopt hand, also can be self-action.
Preferably, in order to keep stable constant in stove, in body of heater, be also provided with a circulating fan for driving BH gas stream in the stove to circulate.By circulating fan by hot and cold air mixing in stove, thus keep constant without difficulty.
More specifically, in the data that the utility model in-furnace temperature is provided by temperature sensors some on body of heater by PLC and program, setting value judges, then the aperture of passing ratio motor 5 auto-control air gas ratio adjusting valve, control the intake of combustion air, the change of air intake, the variation of air pressure can be caused, and then by the intake of air gas ratio regulating valve auto-control natural gas, finally reach and auto-control is carried out to the flame of burner, in order to coordinate the temperature value of actual demand to the lifting amplitude of temperature.
Pressure in stove is the regulation and control by being vented frequency converter, the rotating speed adjustment of air exhauster is guaranteed to the pre-set value of furnace pressure; On blast pipe, increase a damper regulator on the other hand cause thermal loss to prevent stack effect from naturally discharging.
Foregoing; be only preferred embodiment of the present utility model; not for limiting embodiment of the present utility model; those of ordinary skill in the art are according to central scope of the present utility model and spirit; can carry out corresponding flexible or amendment very easily, therefore protection domain of the present utility model should be as the criterion with the protection domain required by claims.
