Description

Waste gas recovery heat exchange device of boiling machine Technical Field The utility model relates to the technical field of heat recovery, in particular to a waste gas recovery heat exchange device of a boiling machine. Background The waste heat recovery device uses a heat exchanger as a main component, and transfers the surplus heat generated by one device to another device for heating or energy conversion, so that the waste heat recovery device is economical and environment-friendly. The heat in the steam drainage waste steam of the boiling machine utilizes the heat exchanger to heat tap water filled in the hot water barrel, but the top of the existing heat exchanger is open, in the production environment, the heat exchanger is positioned on the ground, and objects falling from the upper part can impact the heat exchange net, so that the heat exchange net is easy to damage. In view of this, we propose a waste gas recovery heat exchange device of a boiler. Disclosure of utility model The utility model aims to overcome the defects of the prior art, adapt to the actual needs, and provide the waste gas recovery heat exchange device of the boiling machine, so as to solve the technical problems that the current heat exchanger is positioned on the ground, and objects falling from the upper part can strike a heat exchange net, so that the damage is easy to cause. In order to achieve the aim of the utility model, the technical scheme adopted by the utility model is that the waste gas recovery heat exchange device of the boiling machine is designed and comprises an end box and a heat exchanger main body, wherein the heat exchanger main body is arranged between the two end boxes, and the waste gas recovery heat exchange device also comprises a protection structure; The protective structure is arranged above the heat exchanger main body; the protective structure comprises a cover plate and side plates; A cover plate is arranged above the heat exchanger body; the two side plates are respectively arranged at the front end and the rear end of the cover plate. Preferably, two end tank top ends have set firmly the baffle respectively, the apron is arranged in two between the baffle, apron side end with end tank top end supports the cooperation. Preferably, the inner side of the top end of the baffle plate is provided with an inclined plane. Preferably, two ends of the side plate are respectively connected with the cover plate through a plurality of connecting components; The connecting component comprises a connecting rod, a limiting block and a spring; The connecting rod is arranged in the hole at the end part of the side plate in a penetrating way; wherein the inner end of the connecting rod is fixedly connected with the cover plate; The limiting block is fixedly arranged at the outer end of the connecting rod; the spring is sleeved on the connecting rod between the limiting block and the side plate.
