Description

Technical Field

[0001] This utility model relates to the field of combustion furnace technology, specifically to a flow guide for a regenerative combustion furnace. Background Technology

[0002] A regenerative thermal oxidizer (RTO) is a waste gas treatment device. When used, waste gas is introduced into the furnace body and heated. Once the waste gas reaches a certain high temperature, it decomposes into carbon dioxide and water. The high-temperature gas then passes through a heat storage medium inside the furnace body for heat storage. The heat-stored gas is then discharged through the waste gas outlet. The heated heat storage medium then heats subsequent incoming waste gas. The high-temperature waste gas discharged from the furnace needs to be guided to the heat storage medium structure via a flow guide structure.

[0003] In practical applications, the flow guiding structure is mostly a straight cylindrical tube. However, the high-temperature exhaust gas discharged from the combustion furnace often contains a large amount of dust particles. When the exhaust gas containing dust particles flows through the flow channel of the heat storage body, it can easily cause blockage, thereby affecting the heat storage effect of the heat storage body. Utility Model Content

[0006] Preferably, a conical hood is connected to the top surface of the horizontal shell near the outer end, a discharge hopper is connected to the bottom surface of the horizontal shell opposite the position of the conical hood, and an axial flow fan is fixedly installed at the opening at the top of the conical hood.

[0007] Preferably, the outer edge of the outer port of the horizontal housing is provided with a rectangular ring plate, an end plate is fixedly connected to the outer side of the rectangular ring plate, the piston cylinder of the telescopic cylinder is fixed on the outer wall of the end plate, and the center of the end plate is provided with a sleeve hole for sliding engagement with the piston rod of the telescopic cylinder.

[0010] Preferably, the support body has weight-reducing grooves on its front and rear sides away from the middle of one end face of the vertical cylinder.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. The flow guide of the regenerative combustion furnace disclosed in this utility model can intercept dust particles in the exhaust gas through a filter screen when guiding the exhaust gas, so as to avoid the problem of easy blockage of the flow channel in the regenerative body.

[0013] 2.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4 This utility model provides a technical solution: a flow guide for a regenerative combustion furnace, wherein the shell base 1 includes a vertical cylinder 1.1 and a horizontal shell 1.2 radially connected to one side of the vertical cylinder 1.1. The outer edge of the outer port of the horizontal shell 1.2 is provided with a rectangular ring plate 1.7; connecting rings 1.3 are fixed to the outer edges of the top and bottom ends of the vertical cylinder 1.1; an annular groove 1.6 is provided on the inner circumferential wall of the vertical cylinder 1.1 at a position opposite to the horizontal shell 1.2; a conical cover 1.4 is connected to the top surface of the horizontal shell 1.2 near its outer end, and a discharge hopper 1.5 is connected to the bottom surface of the horizontal shell 1.2 at a position opposite to the conical cover 1.4.

[0026] Two connecting pipes 2 are respectively connected to the top and bottom ends of the vertical cylinder 1.1. Among them, the connecting pipes 2 are fixedly connected to the connecting ring 1.3 through flanges.

[0027] The movable filter element 3 includes a support body 3.1 and a filter screen 3.2 that are slidably fitted inside the horizontal housing 1.2. A cylindrical groove 3.1.1 is provided between the top and bottom surfaces of the support body 3.1. The outer edge of the filter screen 3.2 is fixedly connected to the inner peripheral wall of the cylindrical groove 3.1.1. One end of the support body 3.1 corresponding to the vertical cylinder 1.1 is an arc-shaped end, and the arc-shaped end of the support body 3.1 is engaged and matched with the annular groove 1.6.

[0028] The end plate 5 is fixedly connected to the outside of the rectangular ring plate 1.7 with bolts, and the center of the end plate 5 is provided with a sleeve hole 5.1 for sliding connection with the piston rod of the telescopic cylinder 6.

[0029] The piston cylinder of the telescopic cylinder 6 is fixed to the outer wall of the end plate 5, and the piston rod of the telescopic cylinder 6 is slidably sleeved with the sleeve hole 5.1. The end of the piston rod is fixedly connected to the middle of the end face of the support body 3.1 away from the vertical cylinder 1.1. The piston rod can be connected to the end face of the support body 3.1 by means of threaded connection or other methods.

[0030] The axial flow fan 4 is installed at the opening at the top of the conical cover 1.4. That is, when the telescopic cylinder 6 pulls the support body 3.1 to a position directly opposite the conical cover 1.4 and the discharge hopper 1.5, the axial flow fan 4 can back-blow and clean the filter screen 3.2.

[0031] In summary, the bottom connecting pipe 2 is connected to the high-temperature exhaust gas outlet of the combustion furnace, and the top connecting pipe 2 is connected to the air inlet of the heat storage structure. That is, the high-temperature exhaust gas discharged from the combustion furnace flows to the heat storage structure through the connecting pipe 2 and the vertical cylinder 1.1. During this process, the filter screen 3.2 traps and adsorbs dust particles in the high-temperature exhaust gas to prevent dust particles from clogging the flow channels within the heat storage structure.

[0032] After the filter screen 3.2 has been used for a period of time, the movable filter element 3 is pulled by the telescopic cylinder 6 to a position directly opposite the conical cover 1.4 and the discharge hopper 1.5. The axial flow fan 4 is then started to back-blow the filter screen 3.2, causing the dust particles trapped and attached to the filter screen 3.2 to be blown off and discharged from the discharge hopper 1.5. To prevent dust particles from spreading into the surrounding air, a collection bag or similar structure can be connected to the bottom of the discharge hopper 1.5.

[0033] In order to reduce the weight of the movable filter element 3, the support body 3.1 is provided with weight reduction grooves 3.1.2 on the front and rear sides of the end face away from the middle of the vertical cylinder 1.1.
