Referring to fig. 1-5, an energy-saving technology utilizing device for an integral natural gas compressor comprises an installation base plate 1, a natural gas engine 2, an output shaft 3 and a compressor 4; the natural gas engine 2, the compressor 4, the generating box 8, the temperature difference generator 13 and the wind driven generator 10 are fixedly arranged on the mounting bottom plate 1; the natural gas engine 2 is connected with a compressor 4 through an output shaft 3, and an air inlet pipe 5 and an air outlet pipe 9 are respectively communicated with two sides of the compressor 4; the air outlet pipe 9 is sealed and penetrates through the two sides of the generating box 8; a convection fan 16 is fixedly arranged in the middle of the lower bottom plate of the generating box 8; an exhaust pipe of the natural gas engine 2 is communicated with a heat dissipation connecting pipe 15, the heat dissipation connecting pipe 15 penetrates through two side plates of the generation box 8, and an air collecting port 11 is fixedly arranged at the tail end of the heat dissipation connecting pipe 15; the wind driven generator 10 is fixedly arranged on the mounting bottom plate 1 opposite to the air accumulation hole; the upper end of the generating cylinder is fixedly provided with a turbine generator 6 through an accumulated air guide cavity 7, the turbine generator 6 is communicated with a condenser pipe 12, the condenser pipe 12 is spirally and fixedly wound on a temperature difference generator 13, and the tail end of the condenser pipe is communicated with a return port 14 of the generating box 8.

The fan blades of the convection fan 16 are porous. The heat exchange between the evaporation liquid in the generation box 8 is accelerated by the convection fan 16, so that the heat dissipation efficiency of the heat dissipation connecting pipe 15 is improved, the liquid resistance in the actual rotation process can be reduced to a great extent by the porous convection fan 16 structure, and a motor with smaller power can be used, so that the purposes of saving energy and fully recycling the waste heat of the natural gas steam are achieved. The air accumulation guide cavity 7 is of a structure with a large lower part and a small upper part, and a turbine generator 6 is fixedly arranged on the upper end surface of the air accumulation guide cavity. The structure with the large lower part and the large upper part can effectively accumulate steam at the air suction inlet of the turbine generator 6, so that the power generation power of the turbine generator 6 is improved.

The gas outlet pipe 9 in the generating box 8 is in a front-back multi-section folded shape, and the multi-section folded shape can effectively reduce the temperature of the gas outlet pipe 9, so that the problem of compressed gas is ensured to a great extent, the safety degree is improved, and in addition, the temperature of compressed natural gas can be effectively utilized to achieve the purpose of energy conservation; the reason that the heat dissipation connecting pipe 15 is folded up and down in the generation box 8 and the heat dissipation connecting pipe 15 is in a multi-section folding shape and is vertically distributed with the air outlet pipe 9 is that because the heat dissipation connecting pipe 15 is in a flat structure, a gap in the middle is needed to be matched with the convection fan 16 to carry out temperature exchange on high-temperature liquid and low-temperature liquid, and the steam power generation efficiency is improved; and the convection fan 16 is fixedly arranged on the bottom plate of the generation box 8 at the middle position of the air outlet pipe 9 and the heat dissipation connecting pipe 15, and convection can be better formed at the middle position.

Wherein, the upper and lower surfaces of the heat-radiating connecting pipe 15 are provided with a plurality of bevel edges 17 which are connected end to end; the contact area with surrounding liquid is increased, the heat conduction efficiency is increased, the power generation efficiency is improved, and the residual heat of the combustion of the natural gas can be fully utilized; and the upper and lower surfaces of the heat dissipation connecting pipe 15 are zigzag. The air trap 11 is in a closed shape, and the size of the end face contacting with the heat dissipation connecting pipe 15 is larger.

It is ensured that the temperature of the heat-dissipating connecting pipe 15 can be sufficiently absorbed.

When in use, the working process of the device is as follows: the natural gas engine 2 combusts natural gas with low density so as to drive the output shaft 3 to rotate, the output shaft 3 transmits power into the compressor 4, and the compressor 4 compresses the low-density natural gas led in from the air inlet pipe 5 and then discharges the compressed low-density natural gas with high temperature through the air outlet pipe 9; meanwhile, the tail gas after the combustion of the natural gas is carried with high temperature and is discharged through the heat dissipation connecting pipe 15; when tail gas passes through the generating box 8, as the contact area of the tail gas and steam liquid is enlarged under the action of the inclined edge 17, high temperature can be quickly absorbed by the steam liquid to cause liquid gasification, a large amount of steam is generated, and the steam drives the turbine generator 6 to generate electricity through the accumulated gas guide cavity 7; the steam after pushing the turbine generator 6 is condensed into liquid through a condensing pipe 12 in contact with a temperature difference generator 13 and then flows into the generating box 8 through a return port 14 for recycling; it should be noted that the steam passing through the condensation pipe 12 still has residual temperature, so the steam will drive the thermoelectric generator 13 to generate electricity through heat transfer.

Further: the exhaust gas discharged from the heat-dissipating connecting pipe 15 is collected through the air collecting port 11, thereby driving the wind power generator 10 to generate electricity. Due to the action of the convection fan 16, the liquid in the generation tank 8 is flowing, the gasification process is balanced, and further, the temperature absorption of the heat radiation connecting pipe 15 and the air outlet pipe 9 is efficient.

The device has simple structure, good energy-saving effect and good market application prospect.
