The invention discloses a safe and environment-friendly gas mixing heat energy expansion device and a construction method. The device and method are used for mainly solving the problems that existinggas blasting is unsafe to use and severe in pollution. The device is characterized by comprising a gas tank (1) and an ignition mechanism (2); a depressurizing port (12) and inlets (11) connected withan oxygen source are formed in the gas tank; an accommodating cavity (12) communicating with the inlets and the depressurizing port is formed in the gas tank; and the ignition mechanism comprises anignition head (21) which is arranged in the accommodating cavity. According to the safe and environment-friendly gas mixing heat energy expansion device and the construction method provided by the invention, on one hand, the expanding gas is oxygen, no traditional heating device is needed, pollution is small, on the other hand, the depressurizing port is formed, if blasting fails, staff only needto wait until the high-purity oxygen dissipates from the depressurizing port, and the device is safe and reliable.

The invention discloses a horizontal enhanced vapor injection compressor with an asymmetric extension angle scroll plate, and relates to the technical field of scroll compressors, in particular to a horizontal enhanced vapor injection scroll compressor. A scroll extension angle on a fixed scroll plate and a scroll extension angle of a movable scroll plate form an asymmetric structure; a compression cavity A1 is formed between the scroll inner side of the fixed scroll plate and the scroll outer side of the movable scroll plate; a compression cavity B1 is formed between the scroll inner side of the movable scroll plate and the scroll outer side of the fixed scroll plate; during the enhanced vapor injection communication gas supply period, gas mixing between the compression cavity A1 and the compression cavity B1 is avoided through an enhanced vapor injection communication hole; and in the enhanced vapor injection communication air supply period, air mixing between each of the compression cavity A1 and the compression cavity B1 and a pressure tapping hole is avoided. Only one part of the end face of the fixed scroll plate is provided with an enhanced vapor injection communication hole.
