Example 1:
in order to solve the problems that dust is generated in the sintering process in the prior art, because the components are complex, the electric dust cannot be effectively removed, and if the bag dust is used, the number of filters for the bag dust is increased, or the number of the bag dust collectors is increased to improve the dust removal efficiency, the occupied area is increased, and the construction and maintenance cost is increased; therefore, in contrast, there is a problem that the efficiency of using a single bag-type dust collector is low, and the flue gas dust removal device for sintering process provided in embodiment 1 of the present utility model, as shown in fig. 1, includes: the dust collecting box comprises a box body 1 for supporting and protecting, an ash bucket 2 for receiving dust, an air inlet pipeline 3 for inlet air and an air outlet pipeline 4 for outlet air, wherein the box body 1 comprises a first air purifying chamber 11 and a second air purifying chamber 12; the first air-purifying chamber 11 is separated from the second air-purifying chamber 12 by a partition 13; the partition 13 is provided with an opening 131 for communicating the first air purifying chamber 11 and the second air purifying chamber 12; the first air purifying chamber 11 is communicated with the air inlet pipeline 3; the second air purifying chamber 12 is communicated with the air outlet pipeline 4; a plurality of electrode plates 111 are arranged in the first air purifying chamber 11; a plurality of filters 121 are arranged in the second air purifying chamber 12; an ash bucket 2 is respectively arranged below the first air purifying chamber 11 and the second air purifying chamber 12 in a communicating way.
When the flue gas dust removal device for the sintering process provided by the embodiment 1 of the utility model works, waste gas of the sintering process enters the first air purifying chamber 11 through the air inlet pipeline 3, and primary dust fall is carried out through the electrode plate 111 electrified in the first air purifying chamber 12 (the electrode plate electrified to adsorb dust is in the prior art); after primary dust fall, the waste gas flows into the second air purifying chamber 12 from the opening 131 on the partition plate 13, and secondary dust fall is carried out through the filter 121 in the second air purifying chamber 12; the first air purifying chamber 11 forms an electric dust removing space, the second air purifying chamber 12 forms a bag type dust removing space, the waste gas passes through the first air purifying chamber 11, part of dust in the dust-removing waste gas can be efficiently and quickly removed through electric dust removing, and the waste gas carries dust and part of residues which cannot be removed by the electric dust removing to enter the second air purifying chamber 12 for complete dust removing treatment; the dust finally falls into the dust hopper 2, and the waste gas after twice dust fall leaves the box 1 from the air outlet pipeline 4. Wherein, the partition 13 is to prevent the exhaust gas from entering the case 1, and then directly moving towards the filter 121 without being dusted by the electrode plate 111, so as to cause the load operation of the second air purifying chamber 12 to damage the filter 121; in this embodiment, the electric dust collection in the first air purifying chamber 11 is performed with high efficiency and fast dust collection, so that dust in the waste gas is reduced, the net gas strength requirement of the bag dust collection in the second air purifying chamber 12 is reduced, and the bag dust collection of the second air purifying chamber 12 can perform comprehensive secondary dust collection on the waste gas generated by primary dust collection, so that compared with the direct use of the bag dust collection, the floor area is reduced, and the combination of the electric dust collection and the bag dust collection achieves the technical requirements of high efficiency and wide dust collection.
The flue gas dust removal device for the sintering process provided by the embodiment 1 of the utility model solves the problem that single dust generated in the sintering process adopts bag type dust removal and has low efficiency; the embodiment of the utility model comprehensively utilizes the advantages of electric dust removal and bag type dust removal, mutually compensates the defects, and achieves the dust removal effect with higher efficiency and wide range.
For guiding the exhaust gas into the tank 1 to be discharged, in the present embodiment, a negative pressure fan 5 is further included; the negative pressure fan 5 is communicated with the air outlet pipeline 4; the negative pressure fan 5 can suck out the gas in the second gas purifying chamber 12 to the outside of the box body 1. After the waste gas enters the box body 1, the waste gas is blocked by the partition plate 13 and the filter 121 and remains in the box body 1, and the negative pressure fan 5 is arranged at the air outlet pipeline 4 to continuously suck the gas in the box body 1, (the waste gas flows to the air outlet pipeline 4 after passing through the filter 121), so that the outflow of the waste gas can be quickened, the flow of the waste gas is quickened, and the waste gas purifying efficiency is improved.
After the dust is adsorbed by the electrode plate 111, the dust on the electrode plate needs to be cleaned at regular time to ensure the normal operation of the electrode plate 111, and in the embodiment, the ceramic blowing pipe 6 and the air bag 7 are also included; the ceramic blowing pipe 6 is arranged in the first air purifying chamber 11; the ceramic blowing pipe 6 includes a plurality of nozzles 61 for blowing air toward the electrode plate 111 and an air inlet 62; the air inlet 62 is communicated with an air bag 7. The ceramic blowing pipe 6 made of the ceramic insulating material can prevent the circuit influence from being generated in the blowing process of the electrode plate 111; the specific operation is as follows: by controlling the air bag 7 to blow towards the air inlet 62, air flow is sprayed out from the nozzle 61, the electrode plate 111 is blown to clean dust, and the dust falling from the electrode plate 111 finally falls into the dust hopper 2.
In order to better utilize the characteristics of electric dust removal and bag dust removal in combination, the size of the opening 131 in the partition 13 is adjustable in this embodiment, due to the uncertainty of the composition of the flue gas produced by the sintering process.
