Description

Technical Field

[0001] The utility model belongs to the technical field of tail gas treatment, and in particular relates to a self-cleaning device for a tail gas processor. Background Art

[0002] During the continuous production process of the machine, when the machine processes the exhaust gas of the dry pump, the exhaust gas can be processed into wastewater that can be treated by the factory. However, there are often dust particles and other material components in the exhaust gas. When the exhaust gas is treated into liquid wastewater, dust particles and other materials often appear. The conversion into solid products will cause the products to block the pipeline at the exhaust gas inlet during the actual operation, which is more difficult to handle.

[0003] In view of the above problems, the traditional solution is to frequently dismantle the pipeline to clean the products. This method reduces the use time of the corresponding machine, reduces production efficiency, and seriously affects the production level of the enterprise. It is necessary to design a processing device that can promptly dispose of these products without dismantling the pipeline, so as not to affect the normal use of the pipeline. Utility Model Content

[0004] In order to solve the technical problem in the background technology that dust particles mixed in the exhaust gas will form products that block the pipeline and are difficult to clean, the purpose of the utility model is to provide a self-cleaning device for an exhaust gas processor to solve the above problem.

[0005] The technical solution for achieving the purpose of the utility model is: a self-cleaning device for an exhaust gas processor, comprising an exhaust gas exhaust pipe and a spray device, wherein the spray device is installed in the exhaust gas exhaust pipe and is used to clean dust products that clog the exhaust gas exhaust pipe.

[0006] In the machine processing the exhaust gas of the dry pump, we will use other spray devices to convert the exhaust gas into wastewater, and then discharge it from the exhaust gas emission pipe. However, the dust and other particulate impurities usually contained in the exhaust gas will form dust products in the exhaust gas emission pipe. After blocking the exhaust gas emission pipe, the exhaust gas and the converted wastewater cannot be discharged normally. In this scheme, a spray device is installed in the exhaust gas emission pipe, and water or other liquids containing chemical components can be sprayed through the spray device, and the dust products will be dissolved by the sprayed water to solve the problem of pipe blockage. The wastewater generated after dissolution is discharged from the exhaust gas emission pipe. Compared with the traditional problem of dismantling the pipe to clean the dust products, the added spray device has a simple structure, and spraying water on the dust products can solve the problem of pipe blockage, which greatly improves the processing efficiency and the overall production efficiency.

[0007] Furthermore, the spray device includes a spray pipe and a spray head, the spray pipe extends into the exhaust pipe, and the spray head is installed at the end of the spray pipe. One end of the spray pipe is connected to a water source, and the other end is installed with a spray head for spraying water. The spray head can form a strong spray of water onto the dust products. It can be foreseen that not only can the dust products be dissolved by water, but also the spray force formed by the spray head can directly destroy the dust products, thereby solving the problem of pipeline blockage.

[0008] Furthermore, the nozzle is directed toward the top of the exhaust pipe, that is, when the exhaust gas is discharged from the exhaust pipe from top to bottom, the water sprayed from the nozzle arranged in the opposite direction to the exhaust gas discharge is sprayed from bottom to top in the exhaust pipe. Such an arrangement can prevent dust products from clogging the top of the exhaust pipe, a problem that cannot be solved by the nozzle arranged downward; it can also prevent the problem of dust products adhering to the spray pipe.

[0009] Furthermore, the spray pipe is located in the upper middle part of the exhaust pipe, which further solves the problem that when the dust products are blocked in the upper part of the exhaust pipe and the spray device is located in the lower part of the exhaust pipe, water cannot be sprayed on the dust products.

[0010] Furthermore, a control water valve is provided on the spray pipe. When it is necessary to remove dust products in the exhaust pipe, the control water valve is opened, and the nozzle sprays water upward to dissolve the dust products, thereby solving the pipe blockage problem; when cleaning is not required, the control water valve is closed to save water.

[0011] Furthermore, it also includes a solenoid valve, which is connected to the control water valve through an air pipe and is used to control the opening and closing of the control water valve. The solenoid valve is used to automatically control the opening and closing of the control water valve. For example, when the machine pressure difference is greater than (-15MPA) pressure, an alarm electrical signal 24V will be sent directly to the solenoid valve. After the solenoid valve is energized, air is supplied to the control water valve, and the control water valve is opened to spray water in the exhaust pipe.

[0012] Furthermore, the nozzle is slidably arranged in the spray pipe. When not spraying water, the nozzle can be slid into the spray pipe and hidden, so that the product will not adhere to the nozzle and cause nozzle clogging.

[0013] Furthermore, the bottom of the exhaust pipe is connected to a water tank, and wastewater converted from exhaust gas, wastewater after dust products are dissolved, and water sprayed by the spraying device all fall into the water tank and can be reused after storage, thus saving water resources.

[0014] By adopting the above technical solution, the utility model has the following beneficial effects:

[0015] (1) A spray device is installed in the exhaust pipe connected to the machine. When the exhaust pipe is blocked by dust products, the dust products can be cleaned without dismantling the pipe;

[0016] (2) The spraying device includes a nozzle for spraying water. The sprayed water can dissolve the dust products. The nozzle has a certain spray force and can also directly break up and remove the dust products by water force;

[0017] (3) The nozzle is directed toward the upper part of the exhaust pipe to prevent the problem that dust generated above the nozzle cannot be removed;

[0018] (4) The spray device is located in the upper middle part of the exhaust pipe, which further prevents the problem that the dust generated is located above the exhaust pipe and cannot be removed by spraying water;

[0019] (5) The control water valve is automatically controlled by means of a solenoid valve, and the system is automatically controlled, thereby improving the degree of automation of the entire dust generation removal system. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Example:

[0024] like Figure 1As shown, this embodiment provides a self-cleaning device for an exhaust gas processor, including an exhaust gas discharge pipe 1 and a spray device, wherein the spray device is installed in the exhaust gas discharge pipe 1, and is used to clean the dust products 8 blocked in the exhaust gas discharge pipe 1. In the machine processing the exhaust gas of the dry pump, we will use other spray devices to convert the exhaust gas into wastewater, and then discharge it from the exhaust gas discharge pipe 1. However, the particulate impurities such as dust usually contained in the exhaust gas will form dust products 8 in the exhaust gas discharge pipe 1, and after blocking the exhaust gas discharge pipe 1, the exhaust gas and the converted wastewater cannot be discharged normally. In this scheme, a spray device is installed in the exhaust gas discharge pipe 1, and water or other liquids containing chemical components can be sprayed by the spray device, and the dust products 8 will be dissolved by the sprayed water, solving the problem of pipe blockage, and the wastewater generated after dissolution is discharged from the exhaust gas discharge pipe. Compared with the traditional method of dismantling the pipeline to clean the dust products 8, the added spray device has a simple structure and can solve the problem of pipeline blockage by spraying water on the dust products 8, which greatly improves the processing efficiency and the overall production efficiency.

[0025] Preferably, the spray device comprises a spray pipe 2 and a spray head 3, wherein the spray pipe 2 extends into the exhaust pipe 1, and the spray head 3 is installed at the end of the spray pipe 2. One end of the spray pipe 2 is connected to a water source, and the other end is installed with a spray head 3 for spraying water. The spray head 3 can be used to spray water onto the dust product 8 with force. It can be foreseen that the dust product 8 can be dissolved not only by water, but also directly destroyed by the spray force formed by the spray head 3, thereby solving the problem of pipeline blockage.

[0026] Preferably, the nozzle 3 is directed toward the top of the exhaust pipe 1, that is, when the exhaust gas is discharged from the exhaust pipe 1 from top to bottom, the water sprayed from the nozzle 3 arranged in the opposite direction to the exhaust gas discharge is sprayed from bottom to top in the exhaust pipe 1. Such an arrangement can prevent the dust products 8 from being blocked above the exhaust pipe 1, a problem that the nozzle 3 arranged downward cannot solve; it can also prevent the dust products 8 from adhering to the spray pipe 2.

[0027] Preferably, the spray pipe 2 is located in the upper middle part of the exhaust pipe 1, further solving the problem that when the dust product 8 is blocked in the upper part of the exhaust pipe 1 and the spray device is located in the lower part of the exhaust pipe 1, water cannot be sprayed onto the dust product 8.

[0028] Preferably, a control water valve 4 is provided on the spray pipe 2. When it is necessary to remove the dust products 8 in the exhaust pipe 1, the control water valve 4 is opened, and the nozzle 3 sprays water upward to dissolve the dust products 8, thereby solving the pipe blockage problem; when cleaning is not required, the control water valve 4 is closed to save water.

[0029] Preferably, it also includes a solenoid valve 5, which is connected to the control water valve 4 through an air pipe 7 and is used to control the opening and closing of the control water valve 4. The solenoid valve 5 is used to automatically control the opening and closing of the control water valve 4. For example, when the machine pressure difference is greater than (-15MPA) pressure, an alarm electrical signal 24V will be sent directly to the solenoid valve 5. After the solenoid valve 5 is energized, air is supplied to the control water valve 4, and the control water valve 4 opens to spray water in the exhaust pipe 1.

[0030] Preferably, the nozzle 3 is slidably arranged in the spray pipe 2. When water is not sprayed, the nozzle 3 can be slid into the spray pipe 2 and hidden, so that the product will not adhere to the nozzle 3 and cause the nozzle 3 to be blocked. Specifically, a telescopic motor and a sliding track can be arranged in the spray pipe 2. The telescopic motor can drive the nozzle 3 to slide in the spray pipe 2 along the sliding track. When water needs to be sprayed, the nozzle 3 slides to the end of the spray pipe 2.

[0031] Preferably, the bottom of the exhaust pipe 1 is connected to a water tank 6, and wastewater converted from exhaust gas, wastewater after dust products 8 are dissolved, and water sprayed by the spraying device all fall into the water tank 6 and can be reused after storage, thus saving water resources.

[0032] Working principle: After the dust product 8 in the exhaust pipe 1 blocks the pipe, the solenoid valve 5 controls the control water valve 4 to open, and the nozzle 3 sprays water upward, and the water dissolves the dust product 8 into liquid and then falls into the water tank 6 below for reuse. It should be noted that the nozzle 3 sprays water upward, and the entire spray device is located in the middle and upper part of the exhaust pipe 1. This is to prevent the dust product 8 from being located in the upper part of the exhaust pipe 1 and the spray device from not spraying water in place and failing to remove the dust product 8.

[0033] The specific embodiments described above further illustrate the purpose, technical solutions and beneficial effects of the present invention. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
