Abstract
The invention discloses a temperature controlled type hot-blast stove which is mainly composed of a combustion chamber, a heat exchange chamber, a hot-blast pumping machine, heat exchange tube sets, an air inlet tube, a hot-blast feeding tube, a fan, a controller and a temperature sensor. Hot air in the combustion chamber is pumped by the hot-blast pumping machine to the heat exchange chamber, the heat exchange tube sets are arranged in the heat exchange chamber, the air inlet tube is connected with air inlets in the heat exchange tube sets, the hot-blast feeding tube is connected with exhaust outlets in the heat exchange tube sets, and the fan is arranged on the air inlet tube. The temperature sensor is arranged in the hot-blast feeding tube, the controller receives temperature information, transmitted by the temperature sensor, in the hot-blast feeding tube, and conducts opening and closing control over the hot-blast pumping machine according to the temperature information, and the controller is a PLC. The plurality of heat exchange tube sets are adopted, heat exchange tubes with fins are adopted, the heat exchange time is prolonged, the heat exchange area is increased, and therefore the heat energy utilization rate is greatly improved. An automatic temperature control device is added, therefore, the heat energy utilization rate is further improved, and energy resources are saved.
Description
Technical field
The present invention relates to a kind of agricultural product processing machinery, specifically a kind of Temperature Control Type hot-blast stove.
Background technology
Blast funnace hot blast stove can be divided into two kinds of heat accumulating type and heat exchange types by operation principle, regenerative hot blast stove, press the heat storage bulb separation formula hot-blast stove (being called for short the ball stove) of hot-blast stove inside and the hot-blast stove of employing checker brick, can be divided into top ignition by combustion system, internal combustion type, external-burnings etc. are several, and improving the hot air furnace hot air temperature is the key technology of intensification of smelting process in BF.How improving wind-warm syndrome, is the direction that the insider studies for a long period of time.Way commonly used is the multifuel combustion high heating value gas, or increases the heat exchange area of stove fillings, or changes material, the density of checker brick, or changes the shape (as heat-storing sphere) of heat storage, and by various methodologies by coal gas and combustion air preheating.Heat accumulating type checker brick hot-blast stove is current modern blast furnace, the most frequently used hot-blast stove form of especially large blast furnace.Advantage: heat-exchange temperature is high, heat utilization efficiency is high, the work air quantity is large, is suitable for large blast furnace need of production.Shortcoming: volume is large, and floor space is large, and acquisition cost is high.The heat exchange type hot-blast stove, the master is that the high temperature resistant heat exchanger of use is core component, these parts can not be used the metal material heat exchanger, can only use the refractory ceramics heat exchanger, blast furnace gas is fully burning in combustion chamber, and the hot-air after burning, through heat exchanger, heat is given to fresh cold air, can make more than the fresh air temperature reaches 1000 degree.Advantage: heat-exchange temperature is high, and heat utilization efficiency is high, and volume is little, and acquisition cost is low.The modern hot blast that uses preheating furnace to carry out the combustion air preheating.Shortcoming: heat-exchange temperature is high less than heat accumulating type, and the use scale is less.
There is following defect in existing heat exchange type hot-blast stove: the one, and heat exchange area is little, and heat utilization rate is low; The 2nd, do not have automatic temperature to control, therefore wasted the energy.
Summary of the invention
The purpose of this invention is to provide the Temperature Control Type hot-blast stove that a kind of heat utilization rate is high.
For achieving the above object, the technical solution adopted in the present invention is:
The Temperature Control Type hot-blast stove, it mainly by burner hearth, Heat Room, take out air-heater, set of heat exchange tubes, blast pipe, send warm-air pipe, blower fan, controller and temperature sensor to form, hot-air in burner hearth is taken out air-heater suction Heat Room, described set of heat exchange tubes is located in Heat Room, blast pipe is connected with the air inlet of set of heat exchange tubes, send warm-air pipe to be connected with the exhaust outlet of set of heat exchange tubes, blower fan is located on blast pipe; Described temperature sensor is located at and send in warm-air pipe, and controller receives the temperature information in warm-air pipe that send of temperature sensor transmission, and carries out switch control according to this temperature information to taking out air-heater.
Described controller adopts the PLC controller.
The described blower fan of taking out air-heater employing frequency conversion type.
Described set of heat exchange tubes is to be formed in parallel by a plurality of heat exchanger tubes, and the surface of each heat exchanger tube is intervally distributed with a plurality of fins along the direction of tube hub line.
Described set of heat exchange tubes is provided with four, and four set of heat exchange tubes are connected in series mutually.
Described set of heat exchange tubes is to be made by aluminum alloy materials.
Beneficial effect of the present invention: owing to having adopted a plurality of set of heat exchange tubes, and adopt the heat exchanger tube with fin, therefore extended heat-exchange time, increased heat exchange area, thereby greatly improved heat utilization rate; Increase the attemperating unit of automation, thereby further improved heat utilization rate, saved the energy.
