Operation process of heat-conducting oil flue gas heating device for pyrolysis gasifier

Abstract

The invention discloses an operation process of a pyrolysis gasifier heat-transfer oil fume heating device. According to the operation process, a saturated fume inlet is arranged at the lower part of the tower body of a heating furnace; an unsaturated fume outlet is arranged at the top of the tower body of the heating furnace; a heat-transfer oil pipeline is arranged in the tower body of the heating furnace; one end of the heat-transfer oil pipeline is connected with the outlet of an oil pump A; the other end of the heat-transfer oil pipeline is divided into two branches for connection; one branch is connected with the inlet of an oil pump B; the outlet of the oil pump B is communicated with the upper part of a clamping sleeve; the other branch is connected into a heat-transfer oil tank through a valve B; the heating device is arranged in the heat-transfer oil tank; the lower part of the heat-transfer oil tank is connected with the inlet of the oil pump A through a pipe I; and the upper part of the heat-transfer oil tank is connected with the lower part of the clamping sleeve through a pipeline II, a valve A and a pipeline III in sequence. The operation process provided by the invention is reasonable in structure, solves the problem that the bag-type dust remover of a conventional pyrolysis gasifier is subjected to bag blockage due to the entrainment of water in fume during a quenching deacidification process, improves the stability and reliability of equipment operation, and has good economic and social benefits in popularization and application.

Description

technical field [0001] The invention belongs to the technical field of garbage pyrolysis gasification incineration, and in particular relates to an operation process of a heat conduction oil flue gas heating device of a pyrolysis gasification furnace. Background technique [0002] The existing pyrolysis gasifier has the problem that after the flue gas is quenched to remove acid, the water vapor entrained in the flue gas will easily cause the bag to stick to the bag, the flue gas cannot pass through the bag filter smoothly and the negative pressure of the bag is not enough, and the operation of the equipment is unstable; while cooling The flue gas in the flue at the furnace outlet is discharged with heat, and the waste heat cannot be effectively utilized, which wastes energy. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned technical problems. [0004] The object of the present invention is achieved in the following way...
