Detailed Description
The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and the scope of the present invention can be more clearly and clearly defined.
As shown in fig. 1 to 2, the dust removing device for petroleum coke conveying system of the present invention comprises a spray scrubber 2 for preliminarily treating dusty gas, an induced draft fan 3 and a washing tank 5, wherein the induced draft fan 3 is connected with the exhaust port of the spray scrubber 2 and introduces the preliminarily treated dusty gas into the washing tank 5. The conveying pipeline of the dust-containing gas is provided with a dust-gas valve 1.
The middle part of the washing tank 5 is provided with a clapboard 51, and an exhaust tube 4 is arranged above the washing tank 5. The bottom of the washing tank 5 is provided with a drain pipe L3, the washing tank 5 is provided with a circulating water interface L1 and a tap water interface L2, the tap water interface L2 is connected with an urban tap water source through a second valve K2, the urban tap water source is connected with the spray washer 2 through a first valve K1, and the circulating water interface L1 is connected with the spray washer 2 through a pair of circulating water pumps 6 and a filter 7 which are arranged in parallel.
The filter 7 is provided with a fourth valve K4 and a fifth valve K5 at two ends thereof, and a bypass valve K3 is provided at two ends of the fourth valve K4 and the fifth valve K5. The filter 7 is made of stainless steel, and a 60-mesh filter screen is arranged in the filter 7.
The spray scrubber 2 is a vertical scrubber. The spray washer 2 is provided with a detachable spray head 21, and the spray direction of the spray head 21 is opposite. Of course, the spray head 21 may be installed according to the actual situation, for example, in a cross-spraying manner, as long as the dust in the dust-containing gas can be washed away.
The whole dust removing device is operated as follows: the dust-containing gas firstly enters the spray scrubber 2 through a dust-gas valve 1, and the spray scrubber 2 is a vertical scrubber, so that the dust-containing gas flows from bottom to top from the bottom of the scrubber for improving the washing effect, and the treated gas is introduced into the washing tank 5 through the induced draft fan 3. In the washing tank 5, the dust-containing gas impacts the water body to generate bubbling, so that the dust content in the dust-containing gas can be further reduced. The dust-containing gas treated by the scrubbing tank 5 is finally discharged from the exhaust funnel 4.
Because the washing tank 5 is provided with the circulating water interface L1, when the water quality in the washing tank 5 is good, the circulating water pump 6 can be started, and the water in the washing tank 5 is taken as circulating water and returns to the spray washer 2 through the filter 7 for spraying, thereby greatly saving the water source. When the water quality in the washing tub 5 is poor or the water level is low, the second valve K2 may be opened to introduce city tap water into the washing tub 5. Alternatively, the user may directly introduce city tap water into the spray washer 2 through the first valve K1 to spray.
In addition, since the filter 7 needs to be replaced or repaired after a long time use, the user may close the fourth valve K4 and the fifth valve K5 and open the bypass valve K3.
The dust removal device has higher dust collection rate and dust removal efficiency, and after the dust removal transformation, the dust concentration of the post is ensured to be less than 10mg/Nm3The discharge concentration of the dust removal system is less than 50 mg/Nm3。
The design idea of the present invention is described above with only one embodiment, and the present invention can be expanded to connect more function modules externally at the same time when the system allows, thereby expanding the functions thereof to the maximum.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that are not thought of through the creative work should be covered within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope defined by the claims.
