Description

Technical field:

[0001] The invention belongs to the field of industrial furnace fume treatment, and in particular relates to a spark catcher. Background technology:

[0002] Industrial furnace flue gas dust removal refers to the process of purifying the flue gas containing a large amount of particulate matter and harmful gases generated by industrial furnaces during the production process, aiming to reduce the emission of pollutants in the flue gas. If the untreated flue gas is directly discharged into the atmosphere, it will cause a series of serious environmental and safety problems. Therefore, flue gas dust removal is an indispensable environmental protection link in industrial production.

[0003] At present, bag filters are recognized as the preferred and efficient equipment for industrial kiln flue gas dust removal, but they face two major challenges in actual application. First, the flue gas may contain spark-like high-temperature particles, which can easily cause bag damage and even cause fire; second, the flue gas may contain large solid particles or droplets, which often cause filter bags to wear or stick. Therefore, it is particularly important and of great practical value to develop an effective and reliable spark capture device to pre-treat the kiln flue gas before sending it to the bag filter for dust removal.

[0004] The patent with announcement number CN210145351U discloses a spark trap flame arrester. Although the patent can pre-collect flammable dust, it uses a filter partition to separate the flame arrester to form a circuitous gas flow channel to achieve the effect of blocking sparks. Although this design can effectively block impurities such as sparks, due to the open nature of the channel, impurities may not be fully and efficiently filtered out, which has certain limitations. Summary of the invention:

[0005] In order to overcome the problem that when bag dust collectors are used to remove dust from industrial furnaces, smoke carrying high-temperature spark particles often causes bag damage and causes leakage of solid particles or liquid droplets in the smoke, the present invention proposes an efficient spark catcher that can effectively intercept smoke containing sparks, large solid particles or liquid droplets, thereby ensuring the safe operation of subsequent key equipment such as bag dust collectors.

[0006] The technical solution adopted by the present invention to solve its technical problems is: a spark catcher, including a smoke inlet, a shell, a smoke outlet, an ash discharge port, a capture plate, and an inclined plate; the smoke inlet and the smoke outlet are respectively arranged on both sides of the shell, the capture plate is arranged inside the shell, the inclined plate is horizontally arranged inside the shell and respectively connects the lowest point of the capture plate and the shell, and the ash discharge port is located at the bottom of the shell.

[0007] Furthermore, the lower half of the shell is a cone bucket, and the inclination angle of its wall plate is greater than the accumulation angle of the dust.

[0008] Furthermore, the capture plates are arranged in multiple layers, and there is a gap between the bottom of the capture plates and the cone bucket.

[0009] Furthermore, the capture plate comprises profile layers, plate layers, mesh layers and fabric layers arranged at intervals, and the profile layers, plate layers, mesh layers and fabric layers are arranged randomly and are all made of non-combustible materials.

[0010] Furthermore, the inclined plate is composed of multiple layers of non-combustible plates which are inclined and arranged in parallel.

[0011] Furthermore, the ash discharge port is provided with a discharge valve.

[0012] The beneficial effects of the present invention are:

[0013] (1) Significantly extend the service life of the bag filter: Through the pre-treatment mechanism of the spark catcher, the flue gas carrying high-temperature spark particles and large-sized solid particles and liquid droplets is effectively blocked from entering the bag filter, effectively avoiding the problem of bag breakage and bag sticking, thereby greatly extending the service life of the bag filter.

[0014] (2) Significantly improved dust removal performance: With the multi-level and flexible configuration of the capture plate and the inclined plate, as well as the innovative design using non-combustible materials, the spark catcher can accurately capture various impurities in the flue gas, significantly enhancing the dust removal effect and ensuring that the flue gas emitted by industrial furnaces strictly complies with environmental protection standards.

[0015] (3) Effectively avoid ash accumulation: The scientific design of the inclination angle of the cone bucket wall ensures that ash will not accumulate at the bottom of the shell, ensuring the smooth operation of the ash discharge port and reducing the maintenance cost of the equipment.

[0016] (4) Ensure safe and stable production: The discharge valve installed at the ash discharge port tightly isolates the smoke leakage during the ash discharge operation, ensuring the smooth operation of the collector and its subsequent dust removal equipment. Description of the drawings:

[0023] The utility model is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0024] [Example 1]

[0025] The present invention is a spark catcher, which is arranged on the flue before the bag filter and can effectively catch sparks and solid particles with larger particle size, liquid droplets, etc. Figure 1 As shown, the present invention comprises a smoke inlet 1, a shell 2, a smoke outlet 3, an ash outlet 4, a cone hopper 5, a capture plate 6, and an inclined plate 7. The smoke inlet 1 and the smoke outlet 3 are respectively arranged on both sides of the shell 2, and the ash outlet 4 is located at the bottom or side of the shell 2 to collect captured sparks, particles or droplets, etc. The capture plate 6 is arranged inside the shell 2, and the inclined plate 7 is arranged in parallel and connects the lowest part of the capture plate 6 and the shell 2.

[0026] The core component of the spark catcher is the catch plate 6, which has the ability to be flexibly configured from single layer to multiple layers, and the size of each layer of the catch plate 6 is customized according to the vertical height of the shell 2 to ensure the best fit. A reasonable gap space is carefully set between the bottom of the catch plate 6 and the cone hopper 5 to ensure the smooth discharge of ash and liquid droplets and avoid accumulation and blockage.

[0027] Each layer of the capture plate 6 adopts a diversified structural design, which is a profile and plate arranged at intervals, and its structure can be mesh or filamentary. These capture plates 6 can be installed vertically or arranged at a specific angle to the vertical line according to actual needs. The capture plates 6 are all made of high-performance non-combustible materials to meet high standards of fire safety requirements. In the process of smoke passing through the capture plate 6, impurities such as sparks, large-sized solid particles and droplets will be efficiently intercepted. This process relies on the precise filtering and capture mechanism of the capture plate 6, thereby ensuring that the smoke dust removal effect reaches the expected goal.

[0028] The inclined plate 7 is composed of multiple layers of non-combustible plates arranged in parallel and inclined to capture impurities such as sparks, large-size solid particles and liquid droplets in the flue gas that may escape through the gap at the bottom of the capture plate 6.

[0029] The flue gas flow area inside the shell 2 is significantly larger than that of the flue gas inlet 1, which effectively reduces the flow rate of the flue gas when it flows through the shell 2. The cone hopper 5, as a key part of the shell 2, is arranged at the bottom area of ​​the shell 2. The accumulation angle of ash refers to the angle formed when ash and other particles are naturally accumulated on the plate wall. The inclination angle of the wall plate of the cone hopper 5 is greater than the accumulation angle of ash, which can effectively prevent the accumulation and retention of ash inside the cone hopper 5, and ensure that the ash can be discharged smoothly through the ash discharge port 4.

[0030] [Example 2]

[0031] The working process of the spark catcher described in the present invention is as follows:

[0032] The flue gas emitted by the industrial kiln first enters the shell 2 through the flue gas inlet 1. In the shell 2, the flue gas velocity gradually decreases due to the expansion of the flow area. Then, the flue gas passes through the capture plate 6 area. The capture plate 6 and its connected inclined plate 7 work together to efficiently intercept impurities such as sparks, large solid particles and droplets in the flue gas. These trapped impurities then slide down the cone 5 and finally gather at the ash discharge port 4. The impurities are safely discharged through the discharge valve installed at the ash discharge port 4. After dust removal, the gas is smoothly discharged from the flue gas outlet 3 through the gap between the capture plate 6 and the inclined plate 7.

[0033] The above-described embodiments are only preferred embodiments of the present invention, but not all feasible embodiments of the present invention. For those skilled in the art, any obvious changes made thereto without departing from the principles and spirit of the present invention should be considered to be included in the scope of protection of the claims of the present invention.
