Problems solved by technology
[0002] In the waste heat recovery industry, the structure is often designed as a smoke tube, so that the waste heat flue gas flows from the heat exchange management of the smoke tube, and the outside of the heat exchange tube is used for heat exchange. In the waste heat flue gas, there are often a lot of harmful substances that are viscous. It is corrosive, and it is easy to block and rot the heat exchange tube, which will have a great impact on the operating life of the heat exchange equipment and increase the operating cost

The invention relates to the technical field of waste heat recovery, in particular to a water-pipe-type waste heat steam boiler. The water-pipe-type waste heat steam boiler comprises a steam drum, thetwo sides of the steam drum are fixedly connected with convection banks in a sleeved mode correspondingly, the convection banks on the two sides are each internally provided with a left membrane walland a right membrane wall, and the ends, away from the steam drum, of the convection banks are fixedly connected with a lower right collecting box and a lower left collecting box correspondingly. According to the water-pipe-type waste heat steam boiler, waste heat smoke is pumped into the steam drum, water is injected into the convection banks from a water inlet, the waste heat smoke transfers heat to the water in the convection banks, and thus the function of recovering the heat in the waste heat smoke is achieved; and the steam boiler transfers the heat of the waste heat smoke from the outside of a pipeline into the pipeline, a method that the heat smoke is pumped into the pipeline is abandoned, thus debris in the smoke is prevented from adhering to the inner wall of the pipeline, dredging of the pipeline is guaranteed, damage to the pipeline is reduced, and the operating cost is lowered.
Description
technical field [0001] The invention relates to the technical field of waste heat recovery, in particular to a water tube type waste heat steam boiler. Background technique [0002] In the waste heat recovery industry, the structure is often designed as a smoke pipe, so that the waste heat flue gas flows from the heat exchange management of the smoke pipe, and the outside of the heat exchange tube is used for heat exchange. In the waste heat flue gas, there are often a lot of harmful substances that are viscous. It is corrosive, and it is easy to block and rot the heat exchange tube, which has a great impact on the operating life of the heat exchange equipment, and at the same time increases the operating cost. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a water tube waste heat steam boiler, which solves the problems raised in the background art above. [0004] In order to achieve the above object, the pre...
