The utility model discloses a kind of hot desorption tail gas back burning device, it is related to soil remediation and waste gas processing technical field, including back burning device ontology, the inside of the back burning device ontology is provided with first air mixing section, ignition combustion section and second air mixing section, tail gas inlet is set in the side above the back burning device ontology, fresh air inlet is provided in the other side above the back burning device ontology.The utility model is extracted by hot desorption to organic waste gas and is sent to combustion chamber incineration, so that it does not need to use conventional adsorption, oxidation and so on to process organic pollution waste gas, so as to not produce secondary pollution, and some combustible organic pollutants combustion can produce heat value, which is just available to provide for the contaminated soil to be repaired heating, can reduce the use amount of natural gas or liquefied petroleum gas, more efficient and energy saving.

The application discloses a multi-return stroke gas boiler and relates to the technical field of gas boilers; the multi-return stroke gas boiler comprises a furnace cylinder, front and rear smoke boxes riveted to the two sides of the furnace cylinder, a furnace bellow arranged in the furnace cylinder, and a back burning chamber fixedly connected to the right side of the furnace bellow; first and second return stroke pipes are movably connected between the back burning chamber and the front smoke box and between the front and rear smoke boxes, respectively; a igniter is movably connected to the left side of the front smoke box; and the front and rear smoke boxes are internally provided with a heat uniformity assembly for assisting smoke flow and increasing the heating uniformity of the return stroke pipes; the capsule extrusion provides power for the smoke, ensures the smooth flow of the smoke in the second return stroke pipe, and drives the driving cylinder to move synchronously when the push plate reciprocates left and right, the driving cylinder drives the sliding block to slide in the sliding groove, thereby driving the first and second return stroke pipes to rotate, so that the hot area of the return stroke pipe is in contact with the cold water area of the soft water, the contact area of the return stroke pipe and the soft water is increased, and the heating efficiency of the soft water is improved.
