Description

Technical Field

[0001] The utility model belongs to the technical field of boiler flame observation, and in particular relates to a boiler combustion flame observation device. Background Art

[0002] In order to protect the environment and public health, people are paying more and more attention to the emission of harmful gases after combustion in coal-fired boilers, gas-fired boilers and fluidized bed boilers. This requires relevant staff to not only conduct a detailed analysis of the gas products after combustion, but also conduct statistical analysis of various parameters and phenomena in the combustion process, including the observation of the combustion flame. Usually, observers will observe the color, size and rising status of the flame through the flame observation window of the furnace at fixed or random time intervals to determine whether the combustion temperature, air-to-fuel ratio are appropriate and whether the combustion is complete, and take pictures of the flame through the observation window for subsequent comparison.

[0003] However, when observing the burning flame, sometimes due to factors such as extremely cold weather, too fine coal powder, and excessive furnace pressure, the glass of the flame observation window may crack or blur, making it impossible for the observer to observe the state of the flame in the furnace in time and take clear flame photos. Since the glass of the flame observation window cannot be replaced during the observation process, if replaced, it will cause external cold air to enter through the window of the observation window, affecting the combustion and the quality of the exhaust gas. Therefore, the observer can only replace the glass of the observation window before the boiler starts to burn or after the boiler is completely cooled down, or directly set up brushes and other components to clean the glass. However, since the brush is not resistant to high temperature and is easily damaged, and the brush is too large to block the flame image, it is not conducive to the observer to observe the flame. Therefore, a boiler combustion flame observation device that can quickly and conveniently replace the glass during the process of observing the furnace combustion flame is now needed. Utility Model Content

[0004] The utility model aims to provide a boiler combustion flame observation device, which can quickly and conveniently replace glass sheets according to needs during the process of observing the combustion flame in the furnace, and effectively prevent external cold air from entering the furnace and affecting the flame combustion during the process of replacing the glass sheets.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A boiler combustion flame observation device comprises a plurality of observation pipes arranged along the height direction of the furnace and horizontally penetrating the side wall of the furnace, and a glass sheet which can be radially inserted into the observation pipe and adapted to the shape of the inner wall thereof; a plurality of sockets adapted to the glass sheet are evenly spaced along the length direction of the observation pipe on the side wall thereof, and a sealing component adapted to the glass sheet is movably arranged on the socket.

[0007] A further improvement of the technical solution of the utility model is that the closing component is an outward-turned cover plate arranged on one side or both sides of the socket through a pin shaft. When the cover plate is arranged on one side of the socket through the pin shaft, the cover plate overlaps with the other side of the socket; when the cover plates are respectively arranged on both sides of the socket through the pin shaft, the two cover plates overlap with each other.

[0008] A further improvement of the technical solution of the utility model is that the observation pipe is a rounded rectangular tube, and the sockets on the observation pipe include a first socket arranged close to the furnace and a plurality of second sockets arranged on one side of the first socket, the width of the second sockets is smaller than the first sockets and at least three sockets are arranged.

[0009] A further improvement of the technical solution of the utility model is that the glass sheet comprises an observation glass sheet adapted to the second socket and a shooting glass sheet adapted to the first socket, and the shooting glass sheet is a water-filled glass sheet.

[0010] A further improvement of the technical solution of the utility model is that an annular component is arranged on the upper end of the glass sheet.

[0011] Due to the adoption of the above technical solution, the technical progress achieved by the utility model is: the observation device of the utility model can quickly and conveniently replace the glass piece according to the needs during the process of observing the burning flame in the furnace, and effectively avoid the external cold air from entering the furnace and affecting the flame combustion during the process of replacing the glass piece.

[0012] The utility model adopts a plurality of observation pipes which are arranged horizontally through the furnace side wall along the furnace height direction, and the plurality of observation pipes are distributed in the upper, middle and lower parts of the furnace, so that observers can observe and study the combustion conditions of the flame in the furnace more comprehensively.

[0013] The utility model adopts a method of evenly opening a plurality of sockets adapted for glass pieces on the observation pipe, so that the glass pieces can be replaced from far to near during the observation process. That is, when the glass piece in the farthest socket is damaged, a new glass piece is first put into the adjacent socket and then the damaged glass piece is taken out, and so on, thereby effectively preventing external cold air from entering the furnace and affecting flame combustion during the process of replacing the glass piece.

[0014] The utility model adopts a first socket adapted for a shooting glass sheet arranged near the furnace, which is convenient for observers to shoot the flame in the furnace at close range through the shooting glass sheet. The shooting glass sheet adopts a water-filled glass sheet with good heat insulation effect, which can effectively prevent the camera from being damaged due to being close to the furnace with excessively high temperature.

[0015] The observation pipe adopted by the utility model is a rounded rectangular pipe and the glass piece is adapted to its shape, so that the glass piece and the observation pipe can withstand greater compressive stress, and at the same time, it is more economical than the common round glass piece and pipe.

[0022] The present invention is further described in detail below in conjunction with the embodiments:

[0023] Embodiment 1:

[0024] like Figure 1-Figure 3 As shown, this embodiment discloses a boiler combustion flame observation device, including a plurality of observation pipes 2 arranged along the height direction of the furnace 1 and a glass sheet 5 that can be radially inserted into the observation pipe 2. The observation pipe 2 is made of the same metal or alloy as the furnace 1, so that the thermal conductivity is balanced to avoid uneven distribution of thermal stress on the glass sheet 5. The observation pipe 2 is a rounded rectangular tube with a length of more than 15 cm, which horizontally penetrates the side wall of the furnace 1 to facilitate the observer to observe and study the combustion of the flame in the furnace 1.

[0025] The glass piece 5 is adapted to the shape of the inner wall of the observation pipe 2, that is, a rectangular structure with four rounded corners. The size of the rounded corners is related to the length and cross-sectional area of ​​the observation pipe 2, so that the glass piece 5 can withstand greater compressive stress while saving economic costs. A plurality of sockets adapted to the glass piece 5 are provided on the side wall of the observation pipe 2 along its length direction, so that the glass piece 5 can just be inserted into the inside of the observation pipe 2 through the sockets. The plurality of sockets are evenly spaced according to the length of the observation pipe 2, and each socket is movably provided with a sealing component adapted thereto, and the sealing component can open or close the socket.

[0026] like Figure 4As shown, the closing component is an outwardly turned cover plate 7 arranged on one side of the socket through a pin shaft 6, the cover plate 7 is adapted to the size of the socket, and the cover plate 7 overlaps with the other side of the socket. The function of the cover plate 7 is to close or open the socket. When a glass sheet 5 is placed in the socket, the cover plate 7 is in an open state, and when no glass sheet 5 is placed in the socket, the cover plate is in a normally closed state.

[0027] The sockets on the observation pipe 2 include a first socket 3 provided at one end of the observation pipe 2 close to the furnace 1 and a plurality of second sockets 4 provided on one side of the first socket 3. The width of the second socket 4 is smaller than that of the first socket 3 and at least three of them are provided. The glass sheet 5 includes an observation glass sheet adapted to the second socket 4 and a shooting glass sheet adapted to the first socket 3. In order to take clear flame photos, the camera needs to be attached to the glass sheet when shooting close to the furnace. Therefore, the shooting glass sheet is selected as a thicker water-filled glass sheet with good heat insulation effect, which effectively prevents the camera from being damaged by high temperature when close to the furnace. The observation glass sheet is selected as a thinner ordinary glass sheet. The upper end of the glass sheet 5 is provided with a ring component 5-1 for easy access.

[0028] When observing the flame, you need to first put the observation glass into the second socket 4 farthest from the furnace 1. If the observation glass is damaged during the flame observation process, put a new observation glass into the adjacent second socket 4 from far to near, and then take out the damaged old observation glass, and so on. This operation can effectively prevent external cold air from entering the furnace and affecting the flame combustion during the replacement of the glass.

[0029] Embodiment 2:

[0030] like Figure 5 As shown, a boiler combustion flame observation device disclosed in this embodiment has the same structure of each component and the connection method between each component except the structure of the closing component, except that:

[0031] The closing component is an outwardly turned cover plate 7 which is respectively arranged on both sides of the socket through a pin shaft 6. The two cover plates 7 are assembled to match the size of the socket, and the two cover plates 7 are overlapped with each other.
