Description
Technical field
The utility model is related to the energy conserving system of the industries such as pharmacy, chemical industry, food, more particularly to a kind of granulation drying energy saving
System.
Background technology
With the continuous social and economic development, human society is to the demand more and more higher of the energy, but resource is limited
It is not inexhaustible, the contradiction of the increasingly increased energy resource consumption of the mankind and waste and the continuous reduction of the energy is more and more sharp,
For the long-term stability of human society, people constantly explore the development and utilization for attempting new energy, while increasing income also more
Focus on throttling, also constantly explore the efficient utilization of the energy, social resources can significantly be saved by improving energy utilization rate, according to system
The development in science and technology degree using energy source level difference according to various countries is counted, the energy for having 43%~70% is mainly lost in the form of used heat
Lose, the energy that this explanation also has 30% even with horizontal highest country is wasted, and in the low country of utilization rate, is then connect
Nearly 60% energy is slatterned in the form of used heat, thus, how to improve energy utilization rate is a urgent problem to be solved,
In existing pharmaceutical industry, chemical industry and the widely used granulation drying equipment of food service industry, fluid bed, spraying granulation etc. are included
A series of equipment, supply air system form is all-fresh air air system, and wind pushing temperature is high, and temperature of outgoing air is big, and air draft dust is very
Many, traditional heat recovery technology can not realize the recuperation of heat of this part air draft energy.
Summer and spring and autumn transition season, system is using 7 DEG C of (inlet water temperature)/12 DEG C (exit water temperature) cooling water systems pair
Fresh air carries out dehumidification by condensation, after being heated to more than 90 DEG C through steam in feeding granulation drying equipment.Due to empty after cooling and dehumidifying
Temperature degree is relatively low (14 DEG C), is again heated to more than 90 DEG C, there is the using energy source contradiction for first cooling down reheating, and system energy consumption is non-
Chang Gao.And system temperature of outgoing air is up to more than 60 DEG C, energy waste is serious.
Under winter condition, fresh air humiture is low need not to open cooling water system dehumidifying, directly utilize steam pipe coil by fresh air
Feeding granulation drying equipment after more than 90 DEG C is heated to, heating amount is bigger, equally, and temperature of outgoing air is more than 60 DEG C, this part heat
Amount is all emitted into air, causes great energy waste.
The content of the invention
The purpose of this utility model is to overcome the shortcomings of that prior art dries section there is provided a kind of granulation for saving the energy
Can system.
To reach above-mentioned purpose, the utility model uses following technical proposals：
A kind of granulation drying energy saving system of the present utility model, including be sequentially connected blast pipe, dehumidifying section, preheating section,
Bringing-up section, granulation drying equipment, heat-recovery section and exhaust duct, described preheating section and heat-recovery section uses heat pipe, described
Heat pipe circulation pipe is connected between heat-recovery section and preheating section, cycle power device is installed on described heat pipe circulation pipe,
Described blast pipe, dehumidifying section, preheating section, bringing-up section, granulation drying equipment, heat-recovery section and exhaust duct is set to fresh air successively
By blast pipe, dehumidifying section, preheating section, bringing-up section, granulation drying equipment, heat-recovery section and exhaust duct, described fresh air is pre-
Hot arc and heat-recovery section and the media for heat exchange in heat pipe.
The beneficial effects of the utility model are：
Drying equipment heel row of pelletizing is put to the heat slatterned to recycle to greatest extent, energy-saving effect is reached.This practicality
The new heat pipe used is a kind of heat transfer element with very high thermal conductivity, and it passes through the liquid in Totally enclosed vacuum pipe
Evaporation transmits heat with condensing.The big hundred times of the metal such as heat and speed ratio silver, copper that heat pipe can be transmitted.Heat pipe by shell,
Liquid-sucking core and end cap composition, appropriate refrigerant is filled with by being pumped into pipe after negative pressure.When the heated refrigerant evaporation vaporization in one end of heat pipe,
Steam flows to other end releasing heat under small pressure difference and condenses into liquid, and liquid leans on the effect of capillary force along porous material again
Flow back to evaporator section.So circulation, heat reaches the other end by one end of heat pipe.The utility model is used in granulation for the first time
The field of drying, increases by one section of heat exchange coil arranged by heat pipe as preheating section in air inlet, heat pipe coil pipe is arranged in exhaust outlet
The heat-recovery section of composition, then be connected by heat pipe circulation pipe, using the high-termal conductivity of heat pipe, by the heat recovery of exhaust outlet, profit
Before air inlet bringing-up section, as the preheating of air intake, heat recovery, the effect of energy saving are reached.
System is entered by air inlet using the system cold wind, by preheating section, winter after summer is by the section dehumidifying that dehumidifies
It is directly entered preheating section season, preheating section is formed by the heat pipe arrangement of high-termal conductivity, and preheating section is connected with heat pipe circulation pipe, passes through heat
Pipe circulation pipe improves the temperature that the heat of recovery is used for cold wind, then by bringing-up section, air themperature is adjusted to granulation drying
More than 90 DEG C of temperature needed for equipment work.Hot blast then passes through heat by being changed into more than 60 DEG C of hot blast after drying equipment of pelletizing
Exhausting section reclaims the heat in hot blast.Heat-recovery section equally arranges the new heat pipe of high-termal conductivity, and the heat of recovery passes through heat
Pipe circulation pipe, in the presence of cycle power device, preheating section is returned by heat transfer.By using the used heat in air draft to entering
The cold wind of system is preheated, so as to reduce the heat consumption of bringing-up section, reaches the purpose of energy-conservation.
