The invention provides an organic-polymer waste material treating device. The organic-polymer waste material treating device is mainly composed of a flue gas circulation system, a poor oxygen circulation de-chain device, an oil-gas separation system and a waste residue collecting system. The poor oxygen circulation de-chain device is divided into inner cavities and outer cavities; low-temperature poor oxygen gas is delivered by the flue gas circulation system to enter the inner cavities and subjected to a de-chain reaction, high-temperature flue gas is delivered by the flue gas circulation system and subjected to auxiliary heating through the outer cavities to newly enter the flue gas circulation system, waste is subjected to a poor oxygen de-chain reaction to be reacted in the inner cavities to enter the oil-gas separation system and the waste residue collecting system respectively, and efficient separation of oil, gas and residues is formed. According to the organic-polymer waste material treating device, an oxygen-free or poor oxygen de-chain reaction mode is adopted, a polymer is discomposed, then harmful substances are precipitated and collected, and are not discharged into atmosphere to influence the ecological environment, flue gas is recycled in a multichannel mode, the beneficial effects of saving energy and reducing emission are achieved, and the organic-polymer waste material treating device meets the scientific development concept.

The invention discloses a single-and-double-stage switchable heat pump and belongs to the field of heat pump systems. The heat pump comprises a low-pressure system, a high-pressure system and a main heat exchanger connected in parallel between the low-pressure system and the high-pressure system. A first compressor and a first heat exchanger are arranged in the low-pressure system and connected in series with a left side pipeline of the main heat exchanger. A second compressor and a second heat exchanger are arranged in the high-pressure system and connected in series with a right side pipeline of the main heat exchanger. According to the single-and-double-stage switchable heat pump, the low-pressure system and the high-pressure system are formed by single-stage heat pump bodies and connected in parallel through the main heat exchanger, single-stage heat pump refrigerating / heating circulation can be performed as long as the first compressor in the low-pressure system is independently turned on, and cascade heat pump heating operation can be achieved as long as the second compressor is firstly turned on and the first compressor is turned on afterwards. The heat pump system can be freely switched between the single-stage heat pump mode and the cascade heat pump mode, and therefore the purposes of fully utilizing the advantages of both the modes and effectively saving energy and reducing emissions are achieved.

The invention provides a spray pipe for generating power through turboshaft engine tail gas. The spray pipe comprises a spray pipe outer culvert casing (1), a spray pipe inner culvert casing (2), a piston (6), a spring (8), a spring support (7), a permanent magnet (3), a connecting rod (13) and a pressure adjustment valve (11). An outer culvert channel is formed between the spray pipe outer culvert casing and the spray pipe inner culvert casing, wherein the tail gas is guided to be discharged out of a turboshaft engine through the outer culvert channel. The piston is arranged between the spraypipe inner culvert casing and the spring support and can perform reciprocating linear motion. The spring is mounted between the piston and a linear electric generator and is in the compressed state.The permanent magnet is fixed to the spray pipe inner culvert casing and generates attraction force for the piston. The connecting rod is used for enabling the piston to be connected with the linear electric generator, and thus mechanical energy generated through linear reciprocating motion of the piston is transmitted to the linear electric generator so that the linear electric generator can generate power. The pressure adjustment valve is used for conducting pressure adjustment on the tail gas of the turboshaft engine and controllably discharging the tail gas into the outer culvert channel.
