Description
technical field:
The utility model relates to a kind of gas purifying equipment, particularly relates to a kind of low-grade fever absorption drier with screw energy recovery.
background technology:
Compressed air carries out dry drying machine roughly two kinds: freezing type drier and absorption drier, freezing type drier utilizes refrigeration principle to make the compressed air cooling steam isolated wherein carry out drying, the system air demand of this drier is 100%, but dew point can only reach 2 DEG C ~ 10 DEG C, if and dew point will reach subzero, absorption drier is unique selection, as shown in Figure 2, absorption drier is made up of regenerator and adsorption tower, two groups of Pneumatic butterfly valves are connected between regenerator with adsorption tower, first group of Pneumatic butterfly valve connects dry gas outlet, second group of butterfly valve circulates for gas, in current absorption drier, the heat of compression has that the air of gas consumption is all direct has directly drained in second group of butterfly valve, do not regather, and the cooler that the employing two groups having part to improve afterwards is large, pipeline connects comparatively complicated and will do heating compensation, need to consume more energy consumption.
summary of the invention:
The technical problem that the utility model solves is to provide the loss of a kind of minimizing heater, and can play a kind of low-grade fever absorption drier with screw energy recovery reducing effect.
The technical scheme in the invention for solving the technical problem is: a kind of low-grade fever absorption drier with screw energy recovery, comprise and being made up of adsorption tower and regenerator, connected by two groups of Pneumatic butterfly valves between adsorption tower and regenerator, first group of Pneumatic butterfly valve includes valve V1 in parallel, valve V2 and valve V3, valve V4, second group of Pneumatic butterfly valve includes valve V5 in parallel, valve V6 and valve V7, valve V8, first group of Pneumatic butterfly valve connects dry gas outlet, second group of Pneumatic butterfly valve is connected in the main inlet ductwork of compressed air, described main inlet ductwork arranges an air compressor, this air compressor connects a heat reclamation device, described heat reclamation device is a screw blower fan, this screw blower fan comprises a gas outlet and an air inlet, gas outlet connects regenerator by a heater, then after valve V9, be connected to dry gas outlet, air inlet is by being connected to dry gas outlet after valve V10.
Further, in order to regulate the thermal energy displaced from adsorption tower, one control valve is also set between described air inlet and valve V10.
Further, in order to reduce the noise of whole equipment, described second group of Pneumatic butterfly valve connects a muffler.
The beneficial effects of the utility model are: this equipment carries out heat exchange by heat reclamation device and regeneration air, promote the temperature of regeneration gas, reduce the consumption of heater, realize energy recovery object.
accompanying drawing illustrates:
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is the schematic diagram of the utility model structure;
Fig. 2 is the structural representation of conventional absorbtion formula drying machine.
In figure: 1, Pneumatic butterfly valve 2, regenerator 3, control valve 4, adsorption tower 5, heater 6, muffler 7, air compressor 8, screw blower fan 8-1, gas outlet 8-2, air inlet.
detailed description of the invention:
A kind of low-grade fever absorption drier with screw energy recovery as shown in Figure 1, comprise and being made up of adsorption tower 4 and regenerator 2, connected by two groups of Pneumatic butterfly valves 1 between adsorption tower 4 and regenerator 2, first group of Pneumatic butterfly valve includes valve V1 in parallel, valve V2 and valve V3, valve V4, second group of Pneumatic butterfly valve includes valve V5 in parallel, valve V6 and valve V7, valve V8, first group of Pneumatic butterfly valve connects dry gas outlet, second group of Pneumatic butterfly valve is connected in the main inlet ductwork of compressed air, described main inlet ductwork arranges an air compressor 7, this air compressor 7 connects a heat reclamation device, described heat reclamation device is a screw blower fan 8, this screw blower fan comprises an a gas outlet 8-1 and air inlet 8-2, gas outlet 8-1 connects regenerator 2 by a heater 5, then after valve V9, be connected to dry gas outlet, air inlet 8-2 is by being connected to dry gas outlet after valve V10.
Further, in order to regulate the thermal energy displaced from adsorption tower, a control valve 3 is also set between described air inlet 8-2 and valve V10.
Further, in order to reduce the noise of whole equipment, described second group of Pneumatic butterfly valve connects a muffler 6.
Operation principle is mainly divided into two parts, some is that absorbed air adsorbs moisture content through V7 valve inflow adsorption tower 4 after air compressor 7 compression cooling, dry air is discharged to gas on-the-spot from V1 valve, for regeneration, it is divided into heating process to another part, this equipment carries out heat exchange by heat reclamation device and regeneration air, promote the temperature of regeneration gas, reduce the consumption of heater, realize energy recovery object.
It is emphasized that, it is more than better implementation column of the present utility model, not any type of restriction is done in appearance to this utility model, every above embodiment is done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
