The drawings are different, and the corresponding positional relationship may be changed, so that the scope of protection cannot be understood.
In the present invention, the terms "mounted," "connected," "fixed," and the like are to be construed broadly, and may be, for example, fixedly connected or detachably connected, integrally connected or mechanically connected, electrically connected or communicable with each other, directly connected or indirectly connected through an intermediate medium, or communicated between two components, or an interaction relationship between two components. The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art according to the specific circumstances.
Examples:
the invention provides a compound modularized laboratory waste liquid treatment tail gas purifier, the structure of which is shown in figure 1, comprising: the device comprises a filter plate 1, a filler supporting frame 2, a filler 3, a filler box 4, a gasket 5, a first support 6, a second support 7, a box body 8, an access door 81, an ash collecting device 9 and an ash blowing pipe 10.
The box 8 is formed by surrounding four side plates, the top is used as a tail gas inlet, the bottom is used as a tail gas outlet, an access hole is reserved on one side plate, and an access door 81 is arranged outside the access hole.
The inner wall of the box body 8 is fixedly connected with a plurality of groups of supports at intervals; the support close to the tail gas inlet end is a first support 6, and the rest supports which are arranged at intervals are second supports 7; the first support 6 is provided with a filter plate 1; the upper surface of the filter plate 1 is not lower than the lowest end of a connecting port of the box body 8 and the ash collecting device 10; a blowing pipe 10 is connected above one side of the filter plate 1; the side plate of the box body, which is opposite to the blowing pipe 10, is connected with an ash collecting device 9; placing a stuffing box 4 on the second support; the stuffing box 4 is filled with stuffing 3.
In order to stabilize the filler and improve the air permeability of the filler 3, a filler supporting frame 2 is movably arranged in the filler box 4; the stuffing 3 is filled in the stuffing box 4 and takes the stuffing support frame 2 as a support framework;
in order to increase the tightness a gasket 5 is placed between the first support 6 and the filter plate 1, a gasket 5 is placed between the stuffing box 4 and the second support 7, and the width of the gasket 5 extends at least to the side plates of the box 8. This prevents the exhaust gas from entering the next stage directly through the gap between the stuffing box 4 and the second support 7, instead of through the stuffing box 4. The gasket 5 is made of a heat-resistant nonmetallic material.
Preferably, the width of the gasket 5 extends at least to the side plate of the box 8 and is bent upwards to fit the side plate of the box 8, forming an L-shaped structure. One side of the gasket 5 of the L-shaped structure is attached to the side plate of the box body 8, and the other side is positioned between the first support 6 and the filter plate 1 or between the second support 7 and the stuffing box 4. The gasket 5 with such a structure can further ensure the passing path of the exhaust gas.
The functions and detailed structures of the components are as follows:
1. filter plate 1, dust collecting device 9 and dust blowing pipe 10
The filter plate 1 is made of metal or nonmetal materials and is resistant to high temperature. The filter 1 is arranged on the first support 6 near the inlet end of the tail gas, so that the tail gas generated by waste liquid treatment can be ensured to enter the box 8 and then be filtered by the filter 1, and part of dust in the tail gas can be filtered out and deposited on the surface of the filter 1.
By introducing compressed air into the ash blowing pipe 10, ash deposited on the surface of the filter plate 1 is blown into the opposite ash collecting device 10 under the driving action of the air, and is discharged through an ash discharge port at the bottom of the ash collecting device 10.
Soot blowing may be performed periodically.
2. Stuffing box 4
The stuffing boxes 4 are of a modular structure, and each stuffing box 4 can be filled with the same stuffing or different stuffing.

The stuffing box 4 consists of four side plates and a bottom plate, the upper surface of the stuffing box is opened, and a plurality of holes are formed in the bottom plate for tail gas circulation. The width B1 of the void depends on the size of the packing, ensuring that the packing cannot leak out of the stuffing box 4. Meanwhile, the distance B2 between the two gaps satisfies the following conditions: B2-B1=5-20 mm, and ensures that the bottom plate has sufficient exhaust gas flow area.
The height H of the stuffing box 4 is determined according to the nature of the stuffing and is typically 20-200 mm. The transverse and longitudinal dimensions of the stuffing box 4 are smaller than the corresponding dimensions of the box body, thereby being convenient for taking and placing the stuffing box 4 and fully utilizing the space of the box body 8.
2. A first support 6 and a second support 7
The first support 6 is used for supporting the filter plate 1 and is fixed on a side plate of the box body 8, and the upper surface of the upper filter plate 1 is not lower than the lowest end of a connection port of the box body 8 and the ash collecting device 10;
the second supports 7 are used for supporting the stuffing box 4 and are fixed on the side plates of the box body 8 at intervals, and the two supports can be of the same structure, and as shown in fig. 3, the stuffing box is composed of four section steel.
The width a of the support 6 is not less than 20mm, preferably a=20 to 50mm, to ensure a certain strength and rigidity of the support 6, capable of supporting the weight of the stuffing box 4 and the stuffing.
3. Filler support frame 2
The packing support frame 2 is movably arranged in the packing box 4, and the packing support frame 2 serves as a framework, so that the packing is supported, the packing is prevented from moving, and the air permeability of the packing can be increased.
The packing support frame 2 is constructed as shown in fig. 4, and includes a lattice frame formed by interlacing a plurality of longitudinal bars and transverse bars arranged at intervals, and vertical bars fixed to interlacing points of the lattice frame.
The filler supporting frame 2 can be made of a profile, such as a round tube or round steel.
According to the invention, a plurality of second supports 7 and stuffing boxes 4 are arranged in one box body at intervals, so that a plurality of stuffing materials with different functions can be filled in one purifier according to requirements, and different harmful components in the flue gas can be treated. When the packing fails, the access door 7 is opened, the packing box 4 is taken out integrally, a new packing is replaced, and the packing box 4 is filled back integrally.
According to the packing box, the packing support frame 2 is movably arranged in the packing box 4, so that the packing is supported, the packing is prevented from moving, and the air permeability of the packing can be increased.
The purifier of the invention can be used independently or can be used by combining a plurality of purifiers with different functions.
