[0004] The technical scheme has the following deficiencies: first, when the dust remover removes waste gas, the air inlet is arranged below the air outlet, and the nozzles are arranged at the middle position between the air inlet and the air outlet, so that the air inlet directly rises to the air outlet position after being sprayed once, resulting in low contact frequency of gas and water droplets, and the dust particles in the gas cannot fully contact with the water droplets, thereby causing incomplete cleaning of dust particles; second, the water flow directly falls down, and the time of staying in the air is short, resulting in insufficient contact time with dust particles, and also resulting in poor cleaning effect of dust particles.

DETAILED DESCRIPTION

[0022] The technical scheme in the embodiments of the utility model will be clearly and completely described below in combination with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0023] As Figs. 1 to 3 Shown, a dust remover is used spray device, including the shell 1, the water supply assembly 2 is installed on the top of shell 1, the air inlet assembly 3 is set up in one side of shell 1, two water blocking layers 4 are installed in the inside of shell 1, two water blocking layers 4 are in the vertical direction and are in the state of bending in sequence, the oblique water passing groove 5 is uniformly arranged in the middle of water blocking layer 4, the water collecting cavity 6 is set up in the bottom of shell 1, the continuous bending air passing piece 7 is set up between the bottom water blocking layer 4 and the bottom surface in the inside of shell 1, the air outlet pipe 8 is set up in one side of shell 1, the water outlet pipe 9 is installed in the bottom of water collecting cavity 6.

[0024] It needs to be explained that the shell 1 side is provided with three observation windows 10, for observing the inside dust cleaning situation, so as to carry out the outside air supply and water supply control, the shell 1 away from the three observation windows 10 side is provided with a movable door (not shown), for opening and closing the shell 1, convenient for disassembling and repairing each pipeline, also convenient for cleaning the accumulated mud in the water collecting cavity 6 regularly; preferably, the adjacent water passing grooves 5 can be installed with compressed cotton, which strengthens the water retention capacity of the device.

[0025] The water supply assembly 2 includes a main water inlet pipe 21, and the main water inlet pipe 21 is fixedly connected with three branch water pipes 22 on one side, and three nozzles 23 are uniformly installed on the bottom surface of each branch water pipe 22, and each nozzle 23 extends to the inside of the shell 1 through the top of the shell 1.

[0026] The air inlet assembly 3 includes a main air inlet pipe 31, and the main air inlet pipe 31 is fixedly connected with three branch air pipes 32 on one side, and each branch air pipe 32 extends to the inside of the shell 1 through the shell 1 and is located above the top water blocking layer 4, and the air outlet direction of the branch air pipe 32 is perpendicular to the water spraying direction of the nozzle 23.

[0027] It needs to be explained that after the main water inlet pipe 21 obtains water supply, the water flow is divided to each branch water pipe 22, and then is delivered to each nozzle 23 by each branch water pipe 22, and finally is sprayed to the upper space in the inside of the shell 1 by the atomizing nozzle hole on the nozzle 23, because multiple nozzles 23 are used and are uniformly distributed, so that the atomized water droplets are uniformly arranged in the entire space in the inside of the shell 1, at the same time, the gas to be treated with dust particles is evenly divided to each branch air pipe 32 through the main air inlet pipe 31, and then is delivered to the inside space of the shell 1 full of water droplets by each branch air pipe 32, and the air inlet direction is perpendicular to the water spraying direction, so that the contact rate of water droplets and dust particles is effectively improved in the process of mutual collision, and the cleaning effect of dust particles is improved.

[0028] The topmost water blocking layer 4 is higher on the side close to the branch air pipe 32 than on the side away from the branch air pipe 32, and the adjacent two water blocking layers 4 are in the shape of "eight", and the inclination direction of the water blocking layer 4 is the same as the inclination direction of the water passing groove 5 in the inside thereof.

[0029] It should be noted that the water blocking layer 4 is arranged in a slope direction, which is conducive to the water droplets to drop layer by layer by gravity potential energy, so as not to cause water droplet accumulation while slowing down the water droplets; meanwhile, the water blocking layer 4 is arranged in a slope direction, which also separates the water droplets and the gas to be treated, so that the water droplets and the dust particles in the gas are in contact for a short period of time, thereby reserving a certain combination time for dust removal; the multi-layer water blocking layer 4 prolongs the total time of combination of the water droplets and the dust particles; further, since the inclination directions of the adjacent water blocking layers 4 are different, and the direction of the water passing groove 5 in the water blocking layer 4 is different from the inclination direction of the water blocking layer 4, the gas and the water droplets are forced to change direction when passing through the water passing groove 5 of each layer, and the change direction process weakens the inertia of the water droplets and the gas, and reduces the movement speed, thereby prolonging the combination time between the water droplets and the gas, so as to prolong the dust removal combination time and improve the dust removal effect.

[0030] The inner bottom surface of the shell 1 is inclined on both sides of the top of the water collecting cavity 6, and the bottom surface of the water collecting cavity 6 is inclined downward and converges, and the water outlet pipe 9 is installed at the bottom end of the water collecting cavity 6; the water flow is guided to the convergence of the water collecting cavity 6 through the inclined slope surfaces on both sides, and the convergent bottom of the water collecting cavity 6 also facilitates the water flow with dust to flow more conveniently to the water outlet pipe 9, thereby delaying the generation of accumulated mud in the water collecting cavity 6, which is conducive to reducing the cleaning frequency of the accumulated mud.

[0031] The air passing member 7 is arranged on one side of the water collecting cavity 6, and the bottom water blocking layer 4 is in a flat plate shape, the air passing member 7 includes a plurality of partitions 71 fixedly connected to the bottom water blocking layer 4 and the inner bottom surface of the shell 1, and a continuous S-shaped air passing channel 72 is arranged between the partitions 71, and the air outlet pipe 8 is installed on one side of the air passing member 7.

[0032] It should be noted that the flat plate-shaped water blocking layer 4 is used to prevent water droplets from entering the air passing member 7, and the air passing member 7 is also arranged on one side of the water collecting cavity 6, that is, the air passing member 7 performs gas discharge after the water flow is cleaned, and the plurality of partitions 71 are used to block the internal water droplets from entering the air outlet pipe 8, thereby improving the cleanliness of the air outlet pipe 8.

[0033] The above describes one embodiment of the present application in detail, but the above description is only a preferred embodiment of the present application, and cannot be considered as limiting the scope of the present application. Any equivalent changes and improvements made within the scope of the present application should still belong to the patent coverage of the present application.
