Abstract
Description
Technical Field
[0001] The present application relates to the technical field of boiler slag discharge equipment, and in particular to a sandwich shell water-cooled boiler slag discharge machine. Background Art
[0002] The slag discharger water tank not only plays the role of cooling and transporting ash, but also forms a water seal to prevent air from entering the furnace through the slag discharge equipment. However, the cooling and heat exchange function of the existing water tank is poor. The environmental humidity in coastal areas is high. When the weather is cold and wet, the high-temperature slag of the boiler and some unburned garbage fall into the water tank of the slag discharger, resulting in a high water temperature in the cooling water tank of the slag discharger. When the water temperature is high, a large amount of water vapor evaporates outward, and when the high-temperature slag is pushed out of the furnace after absorbing water, it still evaporates water vapor outward. In special weather, due to the temperature difference between the inside and outside of the slag pit, the water vapor cannot be discharged, which will lead to high humidity in the slag pool environment and poor equipment operating environment. When operating the crane, it is easy to be covered by a large amount of water vapor. For this reason, the utility model proposes a sandwich shell water-cooled boiler slag discharger.

[0023] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.
[0025] Unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0026] This application provides an embodiment of a sandwich shell water-cooled boiler slag discharger. Figure 1 .
[0027] The sandwich shell water-cooled boiler slag discharger in this embodiment includes: a slag discharger body 1, the slag discharger body 1 includes an inner shell 2 and an outer shell 3, a hollow layer 4 is formed between the inner shell 2 and the outer shell 3, a plurality of guide plates 5 are arranged in the hollow layer 4, and the hollow layer 4 is divided into a one-way fluid channel by the guide plates 5, and a water inlet 6 is arranged at one end of the one-way fluid channel, and a water outlet 7 is arranged at the other end.
[0028] It should be noted that: this sandwich shell water-cooled boiler slag discharger is achieved by adding a shell (outer shell 3) on the basis of the original slag discharger shell (inner shell 2), and a one-way fluid channel is formed between the inner shell 2 and the outer shell 3 by separating them with a guide plate 5. A water inlet 6 is provided at one end of the one-way fluid channel, and a water outlet 7 is provided at the other end. When in use, external cooling water can be introduced to flow in the one-way fluid channel. Since the one-way fluid channel is in direct contact with the boiler slag discharger, the heat of the cooling water tank of the slag discharger can be taken away, thereby improving the cooling and heat exchange effect of the cooling water tank of the boiler slag discharger, reducing the generation of water vapor, and improving the operating environment and operating vision of the slag pit equipment.
[0029] The above is the first embodiment of a sandwich shell water-cooled boiler slag discharger provided in the embodiment of the present application. The following is the second embodiment of a sandwich shell water-cooled boiler slag discharger provided in the embodiment of the present application. For details, please refer to Figure 1 .
[0030] The sandwich shell water-cooled boiler slag discharger in this embodiment includes: a slag discharger body 1, the slag discharger body 1 includes an inner shell 2 and an outer shell 3, a hollow layer 4 is formed between the inner shell 2 and the outer shell 3, a plurality of guide plates 5 are arranged in the hollow layer 4, and the hollow layer 4 is divided into a one-way fluid channel by the guide plates 5, and a water inlet 6 is arranged at one end of the one-way fluid channel, and a water outlet 7 is arranged at the other end.
[0031] It is understandable that the thickness of the hollow layer 4 can be determined according to the model and specifications of the boiler slag discharger, and is not limited here.
[0032] Preferably, the one-way fluid channel may be a serpentine fluid channel.
[0033] The water inlet 6 is connected to an external cooling water inlet pipe, and the water outlet 7 is connected to an external cooling water return pipe, so that the heat inside the slag machine is carried away by the cooling water.
[0034] Valves are provided at the water inlet 6 and the water outlet 7 .
[0035] The water inlet 6 and the water outlet 7 are respectively located at two ends of the outer shell 3 .
[0036] The outer shell 3 is connected to the inner shell 2 by riveting. It can be understood that the sandwich shell water-cooled boiler slag tapping machine can add an outer shell 3 by riveting on the outer shell of the slag tapping machine body 1 (i.e., the inner shell 2) without changing the overall external dimensions and installation dimensions of the boiler slag tapping machine.
[0037] The outer shell 3 may also be formed integrally with the inner shell 2 .
[0038] The material of the outer shell 3 can be Q235 carbon steel.
[0039] The thickness of the outer shell 3 may be 3-5 mm. Preferably, the thickness of the outer shell 3 is 4 mm.
[0040] The heat exchange principle of this sandwich shell water-cooled boiler slag discharger is as follows: the heat in the cooling water tank of the slag discharger is transferred to the hollow layer 4 through the inner shell 2 of the slag discharger. The hollow layer 4 is divided into a one-way fluid channel by the guide plate 5, which guides the fluid to flow in the channel between the hollow layers 4. The contact points between the fluid and the shell form a large number of heat conduction paths. At the same time, the turbulence of the fluid also increases the efficiency of convective heat transfer. Therefore, during operation, the valve switches of the water inlet 6 and the water outlet 7 are opened to introduce external cooling water to flow in the hollow layer 4, which can take away the heat from the cooling water tank of the slag discharger, thereby improving the cooling and heat exchange effect of the cooling water tank of the boiler slag discharger, thereby effectively reducing the generation of water vapor.
[0041] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
