1. ;

  • a kind of measurement pyrolysis furnace COT antiscour anti-coking special electric thermo-couple;

    comprise terminal box (1);

    last protection tube (2);

    armoured thermocouple (3);

    joint flange (4);

    under protect eccentric pipe (5) and measuring junction (6);

    the lower end of wherein said terminal box (1) is connected with the upper end of last protection tube (2);

    fixedly connected with joint flange (4) by flange-interface spare (7) in described lower end of going up protection tube (2);

    fixedly connected with protecting eccentric pipe (5) down in the bottom of described joint flange (4);

    protect the lower end of eccentric pipe (5) to fixedly connected down with measuring junction (6);

    one end of described armoured thermocouple (3) is fixedly connected in the terminal box (1);

    the other end passes protection tube (2) and protects eccentric pipe (5) to be inserted in the measuring junction (6) down;

    it is characterized in that;

    anti-interior neglected loading also is housed between described upward protection tube (2) and the flange-interface spare (7) puts (8);

    heat insulation support column (9) also is equipped with in the outside of described armoured thermocouple (3);

    described heat insulation support column (9) upper end is fixed in the joint flange (4);

    the lower end is passed down and is protected eccentric pipe (5) to fixedly connected with measuring junction (6);

    be provided with thermofin (10) in the space between heat insulation support column (9) lateral wall and following protection eccentric pipe (5) madial wall;

    described measuring junction (6) comprises temperature measuring head (11) and protection body (12);

    accommodate armoured thermocouple (3) in the described temperature measuring head (11);

    described protection body (12) is arranged on a side of temperature measuring head (11);

    it has an anti-mask (13) of master that becomes the α

    angle with surface level;

    described master prevents the width of mask (13) and highly is slightly larger than temperature measuring head (11) that main anti-mask (13) is provided with the wearing layer (14) of antiscour anti-coking.
