Description

Technical Field

[0002] A boiler is an energy conversion device that uses fuel to produce high-temperature steam, hot water and other easily usable energy sources. The boiler will produce flue gas during use. In order to reduce pollution to the environment, it is necessary to use a cooling and exhaust device to treat the flue gas, thereby reducing harm to the environment. The traditional boiler exhaust cooling device consists of a smoke inlet pipe, a cooling device and an exhaust pipe. The flue gas in the pipe is cooled by the cooling device and finally discharged from the exhaust pipe. However, the high-temperature flue gas will corrode the pipe, and the particles brought by the flue gas will adhere to the inner wall of the pipe, which to a certain extent affects the service life of the device. In order to solve the shortcomings of the existing technology, we propose a boiler exhaust cooling device. Utility Model Content

[0020] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0021] As attached Figure 1 To the attached Figure 4 The embodiment of the utility model provides a boiler exhaust cooling device, comprising a base 1, a smoke inlet pipe 2 is provided above the base 1, a smoke exhaust pipe 3 and a cooling assembly 4 are provided below the smoke inlet pipe 2, and the smoke exhaust pipe 3 is located on the right side of the cooling assembly 4, and an auxiliary assembly 5 is provided on one side of the cooling assembly 4;

[0022] The cooling assembly 4 includes a cooling box 41, which is fixedly mounted on the top surface of the base 1. A connecting pipe 42 is fixedly mounted on the inner wall of the cooling box 41. A connecting box 43 is fixedly mounted on the top of the connecting pipe 42. A nozzle 44 is fixedly mounted on the top of the inner cavity of the connecting box 43. A water pump 45 is fixedly mounted on the top of the cooling box 41. The water outlet of the water pump 45 is fixedly connected to a water pipe 46. The water inlet of the water pump 45 is fixedly connected to a water pipe 2 47. The water pump 45 is connected to the nozzle 44 through the water pipe 1 46, and the water pump 45 is connected to the inner cavity of the cooling box 41 through the water pipe 2 47. The inner cavity of the cooling box 41 is provided with a filter screen 48. The top of the filter screen 48 is fixedly connected to a handle 1 49, and the handle 1 49 is detachably mounted on the top of the cooling box 41.

[0023] Among them, the connecting box 1 43 is fixedly connected to the smoke inlet pipe 2, and the connecting pipe 42 and the water pipe 2 47 are respectively located on the left and right sides of the filter 48;

[0024] The water source in the inner cavity of the cooling box 41 is pumped to the nozzle 44 through the water pump 45 and the water pipe 2 47, and the water can be sprayed into the connecting box 1 43 and the connecting pipe 42. After the flue gas enters the connecting pipe 42 from the smoke inlet pipe 2, the sprayed water source will be preliminarily cooled. At the same time, the sprayed water source continuously cleans and cools the inner wall of the connecting pipe 42.

[0025] The inner cavity of the cooling box 41 is filled with water, and the end of the connecting pipe 42 away from the connecting box 43 is immersed in the water in the inner cavity of the cooling box 41. The filter 48 divides the inner cavity of the cooling box 41 into two left and right areas.

[0026] As the flue gas emerges from the bottom of the connecting pipe 42, the water source will directly absorb some of the harmful substances and impurity particles in the flue gas, and the filter 48 can block the impurity particles on the left side of the cooling box 41 cavity, allowing the water pipe 2 47 to draw cleaner water from the right side of the cooling box 41 cavity.

[0027] Among them, the auxiliary component 5 includes a connecting box 2 51, which is fixedly installed on the top surface of the base 1, and the side of the connecting box 2 51 is fixedly connected to the exhaust pipe 52, and the inner wall of the exhaust pipe 52 is provided with a connecting box 3 53, and the inner wall of the connecting box 3 53 is slidably connected to the filter box 54, and the top surface of the filter box 54 is fixedly connected to the handle 2 55, and the handle 2 55 is detachably installed on the top of the connecting box 3 53, the inner wall of the connecting box 2 51 is rotatably connected to the hollow cylindrical frame 56, and the top of the hollow cylindrical frame 56 is fixedly connected to the handle 57, and the outer wall of the hollow cylindrical frame 56 is provided with a circular hole 58, and the bottom of the cooling box 41 is fixedly connected to the drain outlet 59, and the drain outlet 59 is located on the left side of the handle 1 49.

[0028] The inner cavity of the filter box 54 is used to place adsorbent to purify the flue gas. The end of the exhaust pipe 52 away from the second connection box 51 is used to discharge the flue gas and inject new water. The exhaust pipe 3 is fixedly connected to the right side of the cooling box 41. The second connection box 51 is connected to the right area of ​​the inner cavity of the cooling box 41 through the exhaust pipe 3.

[0029] The filter box 54 can further absorb harmful substances in the flue gas, thereby reducing pollution to the environment. The used water source can be discharged through the drain port 59 for easy disposal. New water source is poured into the exhaust pipe 52 to clean and cool the exhaust pipe 52, the smoke exhaust pipe 3 and the inner cavity of the cooling box 41.

[0030] There are two exhaust pipes 52, two connection boxes 53, two filter boxes 54 and two handles 55, which are symmetrically distributed on the front and back sides of the connection box 51.

[0031] By rotating the handle 57 to change the direction of the circular hole 58, the circular hole 58 can be switched between the two exhaust pipes 52, so that when the filter box 54 of one exhaust pipe 52 needs to be replaced, the discharge of smoke does not need to be stopped.

[0032] The working process of this utility model is as follows:

[0033] First, start the water pump 45, and extract the water source in the right area of ​​the inner cavity of the cooling box 41 through the water pipe 2 47, and transport the extracted water source to the nozzle 44 through the water pipe 1 46. When the smoke enters the connecting pipe 42 from the smoke inlet pipe 2, the nozzle 44 sprays water to preliminarily cool the smoke and clean the inner wall of the connecting pipe 42. When the smoke emerges from the bottom end of the connecting pipe 42, it will be cooled by the water source in the inner cavity of the cooling box 41 and absorb harmful substances and foreign particles. At the same time, under the filtration of the filter 48, foreign particles are prevented from entering the right area of ​​the inner cavity of the cooling box 41. At the same time, the filter 48 can be removed by removing the handle 1 49. Clean or replace, and then the smoke is discharged from the smoke exhaust pipe 3. When the smoke reaches the inner cavity of the connecting box 2 51, turn the handle 57 to drive the hollow cylindrical frame 56 to rotate, so that the circular hole 58 is aligned with one of the exhaust pipes 52. At this time, the smoke is discharged from one of the exhaust pipes 52 and is absorbed by the filter box 54 to reduce the content of harmful substances. When the filter box 54 needs to be replaced, turn the handle 57 to switch the direction of the circular hole 58, and discharge the waste water in the cooling box 41 from the drain port 59. At this time, new water can be poured into the exhaust pipe 52, and the exhaust pipe 52, the smoke exhaust pipe 3 and the inner cavity of the cooling box 41 are cleaned and cooled at the same time.
