Description

Technical Field

[0001] This utility model relates to the technical field of dust removal equipment for steelmaking furnaces, and in particular to a high-temperature resistant dust removal equipment for steelmaking furnaces. Background Technology

[0002] During the steelmaking process, steelmaking furnaces generate a large amount of smoke and dust due to various factors such as fuel combustion, metal melting, and chemical reactions. The particulate matter in the smoke and dust can remain suspended in the air for a long time, reducing atmospheric visibility, affecting environmental quality, and posing a threat to human health. Therefore, it is essential to provide a high-temperature resistant dust removal device for steelmaking furnaces.

[0003] In existing technologies, steelmaking furnaces generate a large amount of smoke and dust during the steelmaking process due to various factors such as fuel combustion, metal melting, and chemical reactions. This smoke and dust is often accompanied by high temperatures. When the excessively high-temperature smoke and dust gas enters the dust removal equipment, although the current dust removal equipment can handle the high-temperature smoke and dust gas, the excessively high temperature of the smoke and dust gas will still affect the service life of the dust removal equipment to a certain extent. Furthermore, existing dust removal equipment cannot cool down the high-temperature smoke and dust gas before dust removal, resulting in a shortened service life of the dust removal equipment. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing dust removal equipment cannot cool down high-temperature flue gas before dust removal, which leads to a shortened service life of the dust removal equipment. Therefore, this invention proposes a high-temperature resistant dust removal equipment for steelmaking furnaces.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-temperature resistant dust removal device for steelmaking furnaces, comprising a cooling mechanism, wherein a support mechanism is fixedly sleeved on the outer wall of the cooling mechanism;

[0006] The cooling mechanism includes a support frame, with two pipe supports fixedly connected to the top of the support frame. A front-end dust pipe is movably inserted between the inner walls of the two pipe supports. A water-cooling pipe is movably fitted onto the outer wall of the front-end dust pipe. One end of the water-cooling pipe is fixedly connected to a first water storage tank, and the other end of the water-cooling pipe is fixedly connected to a water pump. A second water storage tank is fixedly connected to one side of the outer wall of the water pump. A dust collection head is fixedly connected to one side of the outer wall of the front-end dust pipe, and a protective shell is fixedly fitted onto the outer wall of the front-end dust pipe.

[0007] Preferably, a rear dust duct is fixedly connected to one side of the outer wall of the front dust duct, a dust collection box is fixedly connected to one end of the rear dust duct, and a dust collection hopper is fixedly connected to the bottom of the dust collection box.

[0008] Preferably, an ash discharge valve is fixedly installed at the bottom of the ash collection hopper, a blower is fixedly connected to the outer wall of the dust collector, and an exhaust pipe is fixedly connected to one side of the outer wall of the blower.

[0009] Preferably, the support mechanism includes a support ring plate.

[0010] Preferably, the bottom of the support ring plate is fixedly connected to four support legs.

[0011] Preferably, the bottom of each of the four support legs is fixedly connected to a foot support plate.

[0012] Preferably, the outer wall of the dust collector is fixedly inserted into the inner wall of the support ring plate, and the bottom of the blower is fixedly connected to the top of the support ring plate.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, under the action of the cooling mechanism, the cooling water inside the second water storage tank is transported to the water-cooling pipe by a water pump. At the same time, the high-temperature gas containing a large amount of dust generated by the steelmaking furnace enters the front dust pipe from the dust collection head. After being cooled by the cooling water in the water-cooling pipe, the temperature of the dust gas is greatly reduced, and then it enters the dust removal box from the rear dust pipe for dust filtration. The cooling water heated by the dust gas is transported to the first water storage tank for recycling. In this way, the high-temperature dust gas generated by the steelmaking furnace is effectively cooled, thereby protecting the entire dust removal equipment, reducing the impact of high temperature on the internal structure of the equipment, improving the service life of the dust removal equipment, and reducing equipment maintenance costs.

[0015] 2. In this utility model, under the action of the support mechanism, the dust collector and the ash collection hopper are supported and connected by the support ring plate. At the same time, four support legs are evenly arranged at the bottom of the support ring plate, so that the support ring plate can evenly support the dust collector, which strengthens the support performance of the dust removal equipment and improves the stability of the entire equipment.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1, as Figures 1-4 As shown, this utility model provides a high-temperature resistant dust removal device for steelmaking furnaces, including a cooling mechanism 1, and a support mechanism 2 is fixedly sleeved on the outer wall of the cooling mechanism 1.

A blower 114 is fixedly connected to the outer wall of the dust collection box 111. An exhaust pipe 115 is fixedly connected to one side of the outer wall of the blower 114.

[0027] The overall effect of Embodiment 1 is as follows: under the action of the cooling mechanism 1, two pipe supports 102 are fixedly connected to the top of the support frame 101 to support the front-end flue gas pipe 103. A water-cooling pipe 104 is movably sleeved on the outer wall of the front-end flue gas pipe 103. At the same time, one end of the water-cooling pipe 104 is fixedly connected to the water pump 106. The outer wall of the water pump 106 is connected to a second water storage tank 107. When the blower 114 starts, the high-temperature flue gas enters the interior of the front-end flue gas pipe (103) from the flue gas collection head 108. The water-cooling pipe 104 movably sleeved on the outer wall of the front-end flue gas pipe 103 flows with cooling water under the action of the water pump 106. After absorbing the heat of the high-temperature flue gas, the cooling water flows into the first water storage tank 105. Through continuous cooling water circulation, the high-temperature flue gas is effectively cooled. A protective shell 109 is fixedly fitted on the outer wall of the front-end dust duct 103 to protect the water-cooling pipe. A rear-end dust duct 110 is fixedly connected to one side of the outer wall of the front-end dust duct 103. After being cooled, the dust flows through the rear-end dust duct 110 and enters the dust collector 111 for dust removal. A dust collection hopper 112 is fixedly connected to the bottom of the dust collector 111.

In this way, the high-temperature dust gas generated by the steelmaking furnace is effectively cooled, thereby protecting the entire dust removal equipment, reducing the impact of high temperature on the internal structure of the equipment, improving the service life of the dust removal equipment, and reducing the equipment maintenance cost.

[0028] Example 2, as Figures 2-4As shown, the support mechanism 2 includes a support ring plate 201, four support legs 202 are fixedly connected to the bottom of the support ring plate 201, and foot support plates 203 are fixedly connected to the bottom of each of the four support legs 202.

The outer wall of the dust collection box 111 is fixedly inserted into the inner wall of the support ring plate 201, and the bottom of the blower 114 is fixedly connected to the top of the support ring plate 201. In this way, the support performance of the dust collection equipment is strengthened and the stability of the entire equipment is improved.

When the blower 114 starts, the high-temperature flue gas enters the interior of the front-end flue gas pipe 103 from the flue gas collection head 108. The water-cooling pipe 104, which is movably fitted on the outer wall of the front-end flue gas pipe 103, flows with cooling water under the action of the water pump 106. The cooling water absorbs the heat of the high-temperature flue gas and flows into the first water storage tank 105. Through continuous cooling water circulation, the high-temperature flue gas is effectively cooled. A protective shell 109 is fixedly fitted on the outer wall of the 3 to protect the water-cooled pipe 104.
