Description

Four sections of thermal cycle kelp drying units

Technical field

The present invention relates to thermal cycle drying technology, and in particular to the application of a main laminaria drying unit, belongs to thermal energy ladder Utilize field.

Background technology

Kelp particle is dried, and commonly used boiler heats air, using hot air kelp particle, by the water in particle Point evaporated, thermal energy among hot wind just discharges it only by once utilizing, and hot-air humidity increases on a small quantity, but simultaneously Not up to saturation, the drying of hot wind blow-through are the significant wastages to the energy.

The content of the invention

Four sections of thermal cycle kelp drying unit heat sources are combustion gas, and the heat that fuel gas buring produces is in two ways to kelp Grain is dried, and is heat radiation drying and heated-air drying respectively.Heated-air drying is divided into three, is waste heat drying materials, heat respectively Radiate return air drying, gas hot-air drying.Radiative oven dry is Gas Infrared heating plate, by infrared radiation heating steel plate, to heat Material is dried in radiant drying case.

Combustion gas produce heat in different humidity with being utilized under temperature conditionss, using the heat finally discharged to sea Band material is preheated, and the kelp after preheating is sent into level-one return air drying chamber by carrier chain and carries out secondary drying, after drying Hot wind is once heated to entering the combustion-supporting air of fuel chamber, makes the air themperature higher into fuel chamber, improves combustion gas combustion Temperature is burnt, by gas infrared radiation plate heating radiation drying chamber, the kelp particle on carrier chain is dried three times, is dried Being used containing water gas as level-one return air drying chamber hot wind afterwards, the high-temperature discharge gas in fuel gas buring room is by filtering, note Enter to gas hot-air drying chamber, gas emission gas temperature is high, for still containing amount of heat after drying, then is changed by air Hot device, reheating is carried out to entering the indoor air that burns.

It is of the invention to be for technical scheme applied to solve the technical problem：

1st, four sections of thermal cycle kelp drying units are divided into hot-air seasoning, and two parts are dried with radiant heat, need to pass through kelp Pre-heating drying, micro humid air hot-air seasoning, radiant heat drying, gas emission hot air seasoning, four-stage is handled, to heat Circulation ladder can be carried out to utilize.

2nd, using the hot gas of front and rear hot air drying box twice, after being heated to air, still possess certain temperature, pass through this portion Hot wind is divided to preheat raw material, as one section of drying.

3rd, heat radiation drying baker is when carrying out radiative oven dry, and the vapor contained in inner air and not up to saturation, are Drying effect is improved, it is necessary to this partial air be extracted out, the air containing a large amount of thermal energy, the kelp for just entering device is carried out Two sections of drying.

4th, heat radiation drying baker is converted for combustion gas by infrared radiation panel, makes the more targeted release of heat, is heated Drying baker, gas-fired infrared radiative oven dry are the 3rd section of drying.

5th, the exhaust gas produced after fuel gas buring be high temperature, low humidity, be pipelined to filter, it is right after impurity screening Kelp particle carries out the 4th section of hot-air seasoning.

6th, gas emission gas is filtered, avoid burning caused by dust kelp particle is polluted.

7th, heat radiation heating can concentrate heat, improve combustion gas directly acting on to drying object, reduce scattering and disappearing for heat.

The beneficial effects of the invention are as follows：

1st, make heat obtain circulation ladder to utilize, reduce gas consumption.

2nd, pair the air with combustion gas mixing heats, and improves ignition temperature.
