Embodiment 1

[0028] Embodiment one is basically as attached Figures 1 to 3 Shown:

[0029] A dust collection device for a boiler, comprising a frame 1, a box 2 is fixedly connected to the frame 1 by bolts, an exhaust port 3 is opened on the box 2, a cloth bag 4 is fixed inside the box 2, and the bottom of the box 2 It is connected with an ash hopper 5, and the bottom of the ash hopper 5 is provided with a dust outlet 6, and a valve 7 is installed on the dust outlet 6, and an air inlet 8 inclined downward along the inner wall of the ash hopper 5 is opened on the side wall of the ash hopper 5, and the The number of air inlets 8 is an odd number greater than one, and the air inlets 8 are distributed in a circular array on the inner wall of the ash hopper 5 . In this embodiment, the number of air inlets 8 is three.

[0030] The frame 1 is provided with a cooling mechanism and a fire extinguishing mechanism. The cooling mechanism includes a cooling tube 9 communicated with the air inlet 8. Th...

Embodiment 2

[0032] Embodiment two is basically as attached Figure 4 Shown:

[0033] The difference between this embodiment and Embodiment 1 is that the cooling mechanism also includes a plurality of nozzles 17 arranged in the box body 2. The nozzles 17 are located below the cloth bag 4 and are distributed in a circular array on the side wall of the box body 2. The box body 2 is fixedly connected with a water tank 18, and a conduit is connected between the water tank 18 and the nozzle 17, and a one-way valve is installed on the conduit to conduct one-way to the tank 2, and a water pump is installed in the water tank 18, which can pump the water in the water tank 18 into In the conduit, water is sprayed from the shower nozzle 17. A water guide pipe 19 is connected between the water tank 18 and the water outlet 14, and a three-way valve 20 is installed on the water guide pipe 19. The box body 2 is fixed with a first filter net 21 and a second filter net 22 by bolts, the cloth bag 4 is loc...

Embodiment 3

[0036] Embodiment three is basically as attached Figure 5 Shown:

[0037] The difference between the present embodiment and the second embodiment is that a temperature sensor 23 is installed on the side wall of the ash hopper 5 close to the air inlet 8, and a controller (not shown) is fixedly connected to the frame 1 by bolts. The water pump, the temperature sensor 23 and the controller form an electrical connection. In this embodiment, the temperature sensor 23 and the controller are both existing in the prior art, and will not be repeated here.

[0038] During specific implementation, the temperature of the gas entering the ash hopper 5 is detected by the temperature sensor 23. When the temperature is too high, the controller controls the water pump to start, and the water in the water tank 18 is introduced into the shower nozzle 17 for spraying to cool down; When it is high, the water pump will not start. The range of this temperature is determined according to the actua...

Abstract

The invention relates to the technical field of dust purification, and particularly discloses a boiler dust collection device. The boiler dust collection device comprises a rack, wherein a box body isfixedly connected to the rack; an exhaust port is formed in the box body; a cloth bag is fixedly connected into the box body; an ash hopper is communicated with the lower part of the box body; air inlets are formed in the ash hopper; the number of the air inlets is an odd number larger than 1; the air inlets are distributed in the inner wall of the ash hopper in a circular array mode; a cooling mechanism and a fire extinguishing mechanism are arranged on the rack; the cooling mechanism comprises a cooling cylinder communicating with the air inlets; a cooling channel and a cavity surrounding the cooling channel are formed in the cooling cylinder; a water inlet and a water outlet are formed in the cavity; the fire extinguishing mechanism comprises a fire extinguishing cylinder; the fire extinguishing cylinder communicates with the cooling cylinder and the air inlets; and a spraying pipe used for spraying a fire extinguishing agent is arranged in the fire extinguishing cylinder. According to the scheme, the problem that in the prior art, the dust removal effect is poor due to the fact that the temperature of dust-containing gas of a bag-type dust collector is too high is solved.

Description

technical field [0001] The invention relates to the technical field of dust purification, in particular to a boiler dust collection device. Background technique [0002] At present, the boiler usually uses a bag filter for dust removal during use. Its working principle is that after the dusty gas enters the bag filter, the dust with large particles and high specific gravity will settle down due to the action of gravity and fall into the ash hopper, containing The gas with finer dust is filtered when it passes through the bag, so that the dust is blocked and the gas is purified. However, the temperature of the dust-laden gas just out of the boiler is generally high, and some even contain sparks, which can easily cause certain damage to the bag, and even cause the bag to catch fire, resulting in a decrease in the filter accuracy of the bag and a shortened service life. The dust removal effect is poor, and the gas with dust is discharged into the atmosphere, causing pollution ...
