Abstract

The utility model discloses an air energy paper drying system, which comprises a drying table, a drying channel, paper, condensation tubes, a compressor, a liquid storage tank, a filter, a capillary tube, an evaporimeter, a fan and an evaporimeter air inlet, wherein condensation tubes are arranged below the drying table, and the evaporimeter and the evaporimeter air inlet are arranged at the tail end of the drying channel. With adoption of the scheme of the utility model, the defects of high cost and environmental contamination of a small-sized paper mill in drying paper by combusting coal are overcome, therefore, the drying system is particularly suitable for medium and small sized paper manufacture enterprises.

Description

A kind of air can the paper drying system

Technical field

The utility model relates to a kind of paper drying system, particularly a kind of when the compressor operating system of condenser liberated heat oven dry paper machine moist paper out.

Background technology

At present, general paper machine paper out is very wet, need to dry with a large amount of heats, small-sized paper mill generally adopts coal to dry paper as fuel now, because energy prices generally go up, coal combustion produces heat oven dry paper high expensive and contaminated environment, has had a strong impact on the profit of papermaking enterprise.

The utility model content

In order to overcome the small-sized shortcoming that causes factory to burn the high and contaminated environment of coal oven dry paper cost, the utility model provides a kind of air energy paper drying system to address this problem, and its good effect is that the use air can be as thermal source, make the paper drying course both save cost, free from environmental pollution again.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of air energy paper drying system of the present utility model, formed by drying station, drying channel, paper, condenser pipe, compressor, fluid reservoir, filter, capillary, evaporimeter, fan, evaporimeter air inlet, employing is furnished with condenser pipe below drying station, be furnished with the technology of evaporimeter and evaporimeter air inlet at the end of drying channel, substitute the system of burning coal oven dry paper.

Description of drawings

Below in conjunction with accompanying drawing, the utility model is further illustrated.

Fig. 1 is the utility model principle schematic.

1. drying stations in figure, 2. drying channel, 3. paper, 4. condenser pipe, 5. compressor, 6. fluid reservoir, 7. filter, 8. capillary, 9. evaporimeter, 10. fan, 11. evaporimeter air inlets.

The specific embodiment

In the embodiment in figure 1, we can the paper drying system further illustrate the utility model as example to implement a kind of air:

In Fig. 1, drying station 1 use metallic plate is made, copper coin and aluminium sheet can, for good heat-conducting effect being arranged and reducing costs, aluminium sheet is good selection; The cuboid passage that drying channel 2 is comprised of drying station and top cover plate; Paper 3 is paper machine wet paper out, is pulled through from drying station 1; Condenser pipe 4 is the condenser of air-energy dryer, is arranged in the below of drying station 1; Compressor 5, fluid reservoir 6, filter 7, capillary 8,, evaporimeter 9, fan 10 be air energy drying system critical piece, operation principle is identical with air-source water heater, difference is exactly the difference that heat is used for hot water and oven dry paper, evaporimeter 9 is arranged in the end of drying channel 2, is provided with evaporimeter air inlet 11 at the drying channel end.

The operation principle of native system is: when the paper machine wet paper with large quantity of moisture was out dragged drying station, the heat that the condenser pipe 4 of drying system gives out is dried paper, the evaporimeter air inlet is constantly extracted the humid air in drying channel 2 out, damp-heat air flows through evaporimeter 9 simultaneously, reclaimed partial heat energy, the drying efficiency of native system is improved greatly.

In the specific implementation, calculate the great compressor horsepower of needs according to the heat energy of oven dry needs, determine again the miscellaneous part of drying system, its technology can be with reference to the manufacturing technology of air-source water heater, because the length of drying channel 2 may be longer, the system that one compressor forms may not realize drying fully, can adopt multiple compressors, a plurality of condenser, a plurality of evaporator bank COST system, the condenser pipe 2 of a plurality of condensers is evenly arranged in below drying station 1, and a plurality of evaporimeters are arranged in the end of drying channel 2.

Adopted scheme of the present utility model, can save a large amount of energy, according to according to a preliminary estimate, a small-sized paper mill will be used 1.5 tons of matchmakers in one day, by 1000 yuan/tons of calculating, need 1500 yuan/day, if use the air energy drying system instead, adopt the compressor of 50 altogether, one day 300 yuan of left and right of the electricity charge, 1200 yuan can be saved, 430,000 yuan can be saved in 1 year, and free from environmental pollution, certainly also there is shortcoming in this system, disposable input is higher, but the expense of the saving of a year is enough to invest this equipment of cover, so still more feasible.

Claims

1. an air can the paper drying system, formed by drying station (1), drying channel (2), paper (3), condenser pipe (4), compressor (5), fluid reservoir (6), filter (7), capillary (8), evaporimeter (9), fan (10), evaporimeter air inlet (11), it is characterized in that: be furnished with condenser pipe (4) below drying station (1), be furnished with evaporimeter (9) and evaporimeter air inlet (11) at the end of drying channel (2).
