Abstract: A method and apparatus for removing pollutants from organic solid waste by pyrolysis coupled with chemical looping combustion are provided. The apparatus includes: an air reactor, a fuel reactor, and a pyrolysis gasifier. The pyrolysis gasifier is sleeved outside the fuel reactor, and the air reactor is connected with the fuel reactor. A top end of the air reactor is connected with a top delivery pipe; the top delivery pipe is connected with a first cyclone separator; and the first cyclone separator is connected with an oxygen carrier refeeder provided at a top end of the fuel reactor. The apparatus forms a two-stage reaction unit of pyrolysis and chemical looping combustion by decoupling the pyrolysis process from the chemical looping combustion, which avoids the contact between the complex ash of organic solid waste and the oxygen carrier, thereby improving the service life of the oxygen carrier.

Abstract: A reciprocating linear/rotational motion conversion device has a main shaft, a linear motion guiding mechanism, a sector gear and a rack frame. The sector gear is fixedly connected with the main shaft. A rack pair is arranged on the inner wall of the rack frame. The rack pair comprises a first gear rack and a second gear rack separately arranged on both sides of the sector gear. The reciprocating linear/rotational motion conversion device further includes a reversing mechanism fixedly connected with the main shaft. A cylinder device contains the reciprocating linear/rotational motion conversion device, connecting rods, pistons and cylinder bodies. The cylinder body is sleeved on the piston, and a cylinder head is arranged on one end of the cylinder body.
