Abstract
The utility model provides a high-temperature variable frequency heat pump heating-based drying system, which consists of a heat pump device, an air inlet duct, a material drying chamber and an air outlet duct, wherein the heat pump device consists of an evaporator, a gas-liquid separator, an air compressor, a condenser and a throttle valve; valves a and b are arranged on the air inlet duct; valves c and d are arranged on the air outlet duct; an electric heater is also arranged on the air inlet duct; a motor is arranged at the lower end of the air inlet duct. According to the drying system, the air inflow and the air outflow are controlled through the valves to realize variable frequency heat pump control; a heat pump technology is adopted, so that energy resources are effectively saved; a heat pump is controlled based on a variable frequency control technology, as a result, remarkable energy-saving effects are achieved.
Description
Technical field
The utility model belongs to technical field of heat pumps, is specifically related to a kind of drying system based on the heating of high temperature frequency conversion heat pump.
Background technology
Along with national economy develops rapidly and the raising of living standards of the people, heating, air-conditioning, domestic hot-water's etc. energy demand is increasing, is the major part of common civil buildings thing energy-consuming.In flourishing city, the energy that summer air-conditioning, winter heating and heat supply consume has accounted for 40～50% of building total energy consumption.The drying system using in industry, is sent to heat energy the oven dry of carrying out material in baking box, and the high temperature heat in baking box is outdoor along with exhaust outlet is discharged into, and the utilization rate of the heat energy of reduction increases the consumption of the energy, causes environmental pollution.
Utility model content
The problem that the utility model exists for above technology, a kind of drying system based on the heating of high temperature frequency conversion heat pump is provided, this system adopts heat pump techniques to heat drying materials chamber, in blast pipe and exhaust duct, valve is set, by valve control air intake and air output, realize frequency conversion heat pump control, adopt heat pump techniques effectively to save the energy, by frequency conversion control technique control heat pump, make energy-saving effect remarkable.
A kind of drying system based on the heating of high temperature frequency conversion heat pump that the utility model provides, this system is made up of heat pump assembly, intake stack, drying materials chamber and wind pipe, described heat pump assembly is made up of the evaporimeter connecting successively, gas-liquid separator, air compressor, condenser and choke valve, valve a and valve b are set on described intake stack, valve c and valve d are set on described wind pipe, on described intake stack, be also provided with electric heater, described intake stack lower end arranges motor.
Described valve a is arranged on the porch of intake stack, controls the inlet of new wind by valve a, and described valve b is arranged on the exit of intake stack, controls the hot blast rate that enters drying materials chamber by valve b.
Described condenser is arranged on intake stack inside, is positioned at the below of electric heater.
Described valve c is arranged on the air inlet of wind pipe, controls the hot blast discharge rate of drying materials chamber, and described valve d is arranged on the air outlet of wind pipe, controls the concentration that contains explosion gas in toxic emission by valve d.
New wind enters intake stack by the porch of intake stack, control intake by valve a, in heat pump assembly, evaporimeter absorbs heat, by gas-liquid separator and air compressor, thermal energy transfer is arrived to condenser, reject heat in intake stack and heat by condenser, hot blast enters into drying materials chamber by valve b under the effect of motor, by valve c, discharge hot blast rate is controlled, control the concentration that contains explosion gas in the waste gas of discharge by valve d, this technology adopts electrical heating to combine with heat pump techniques, be heated to be master with heat pump techniques, by the opening degree of VFC valve, control intake and exhaust air rate number, effectively carry out the saving of the energy.
Accompanying drawing explanation
Accompanying drawing is system construction drawing of the present utility model.
The specific embodiment
A kind of drying system based on the heating of high temperature frequency conversion heat pump the utility model proposes, as shown in the figure, this system is made up of heat pump assembly, intake stack 6, drying materials chamber 10 and wind pipe 14, described heat pump assembly is made up of the evaporimeter 1 connecting successively, gas-liquid separator 2, air compressor 3, condenser 5 and choke valve 4, valve a7 and valve b9 are set on described intake stack 7, valve c11 and valve d13 are set on described wind pipe 14, on described intake stack 6, be also provided with electric heater 12, described intake stack 6 lower ends arrange motor 8.
