Description

Technical Field

[0001] The utility model relates to the technical field of boiler waste heat recovery structures, in particular to a boiler waste heat recovery structure. Background Art

[0002] A boiler is an energy conversion device. The energy input to the boiler includes chemical energy in the fuel and electrical energy. The boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of thermal energy. The original meaning of "pot" refers to a water container heated on fire, and "furnace" refers to the place where fuel is burned. A boiler consists of two major parts: the pot and the furnace. The hot water or steam produced in the boiler can directly provide the required thermal energy for industrial production and people's lives, or can be converted into mechanical energy through a steam power device, or the mechanical energy can be converted into electrical energy through a generator. A boiler that provides hot water is called a hot water boiler, which is mainly used for daily life and also has a small number of applications in industrial production. A boiler that produces steam is called a steam boiler, often simply referred to as a boiler, and is mostly used in thermal power plants, ships, locomotives and industrial and mining enterprises.

[0003] Existing boiler shells are mostly cylindrical in design. When the boiler heats the internal liquid, heat often overflows into the surrounding environment. This heat overflow wastes energy and the waste heat cannot be used to preheat the raw liquid.

[0004] The existing patent (publication number: CN220417686U) discloses a structure for recovering and utilizing waste heat of a boiler, which belongs to the technical field of waste heat utilization of boilers. The key points of its technical solution include a furnace shell and a support frame, a liquid storage tank is installed on the outside of the furnace shell, the liquid storage tank is in an arc shape, the upper part of the liquid storage tank is movably connected with an inlet pipe, the lower part of the liquid storage tank is installed with a water pump and a transmission pipe, the side of the liquid storage tank away from the furnace shell is fixedly connected with a connecting block, and both ends of the lower side of the connecting block are fixedly connected with support legs. This structure for recovering and utilizing waste heat of a boiler, by arranging an arc-shaped liquid storage tank, can first load the raw liquid into the liquid storage tank before heating the raw liquid inside the furnace shell. Since the heating of the furnace shell will dissipate waste heat, the waste heat will heat the liquid storage tank at this time, and then preheat the raw liquid inside the liquid storage tank, so as to achieve the recovery and utilization of the waste heat emitted by the furnace shell, and achieve the effect of environmental protection and energy saving. This device is suitable for cylindrical furnace shells.

[0005] In response to the above problems, existing patents have provided solutions. In the process of recovering boiler waste heat, most existing boilers utilize the heat of the boiler by installing a heat-conducting structure on the surface of the boiler. However, due to the presence of multiple layers of partitions between the heat-conducting structure and the boiler, heat is lost during the conduction process, resulting in low efficiency.

[0006] Therefore, a boiler waste heat recovery structure is proposed. Utility Model Content

[0007] The purpose of the utility model is to provide a boiler waste heat recovery structure, which can solve the problem that in the process of recovering the waste heat of the boiler, most existing boilers utilize the heat of the boiler by adding a heat-conducting structure on the surface of the boiler. However, due to the multi-layer partition between the heat-conducting structure and the boiler, heat is lost during the conduction process, resulting in low efficiency.

[0008] To achieve the above-mentioned object, the present invention provides the following technical solution: a boiler waste heat recovery structure, comprising a boiler body, a recovery component sheathed on the surface of the boiler body, a filter component connected to the rear side of the recovery component, and a protective cover clamped on the top of the boiler body;

[0009] The recovery assembly includes an electronic valve body, a connecting pipe is connected to the top of the electronic valve body, and a circular sleeve is connected to the side of the connecting pipe away from the electronic valve body. The circular sleeve is bolted to the surface of the boiler body, and a cavity sleeve is bolted to the bottom of the circular sleeve. The bottom of the connecting pipe passes through the circular sleeve and is connected to the inner wall of the cavity sleeve. The rear side of the cavity sleeve is connected to a connecting pipe used in conjunction with the filter assembly. The right side of the circular sleeve is fixedly connected to the water pump body, the bottom of the water pump body is connected to a first pipe, and the side of the first pipe away from the water pump body is connected to the inner wall of the circular sleeve. The top of the water pump body is connected to a second pipe, and the side of the second pipe away from the water pump body is connected to the top of the boiler body. The rear side of the circular sleeve is connected to a filling pipe, and a sealing gasket is clamped inside the filling pipe. The rear side of the circular sleeve is fixedly connected to the temperature detector body. A hole is opened on the right side of the circular sleeve. Two fixed blocks are fixedly connected to the right side of the circular sleeve, and a shielding door is rotatably connected to the opposite side of the two fixed blocks.

[0010] Preferably, the side of the connecting tube away from the cavity sleeve is connected to a frame, the frame is bolted to the rear side of the circular sleeve, two filter racks are clamped to the rear side of the frame, an activated carbon storage box is clamped to the rear side of the frame, and the top of the frame is connected to a smoke exhaust pipe.

[0011] Preferably, a top cover is clamped on the top of the smoke exhaust pipe, and a protective net is fixedly connected to the inside of the top cover.

[0012] Preferably, the rear sides of the two filter racks and the activated carbon storage box are fixedly connected with adjustment handles, and the material of the adjustment handles is stainless steel.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. This application, by setting up a recovery component, can achieve the effect of efficiently recovering the waste heat of the boiler. The electronic valve body guides the smoke inside the boiler into the connecting pipe. The high-temperature smoke increases the temperature of the connecting pipe, and then transfers the heat to the liquid material inside the circular sleeve, thereby realizing the utilization of the waste heat. Compared with the traditional method of using a heat-conducting structure with multiple layers of partitions, this method of directly utilizing the heat of the smoke reduces heat loss and improves the waste heat recovery efficiency. There is a filling pipe on the rear side of the circular sleeve, which can guide the liquid material requiring waste heat into the circular sleeve. After the temperature reaches the standard, the water pump body extracts the liquid material inside the circular sleeve through the first pipe, and then guides it back to the boiler body through the second pipe, thereby realizing the recycling of the liquid material, making full use of the waste heat and saving resources.

[0019] 2. This application can achieve the effect of effectively filtering the boiler smoke by setting up a filter component. When the smoke enters the frame through the connecting pipe, the two filter racks connected to the back side of the frame can filter out larger particles of impurities in the smoke, and the activated carbon storage box can absorb harmful gases and some tiny particles in the smoke, thereby making the discharged smoke cleaner and reducing pollution to the environment.
