Description

Technical Field

[0001] The utility model relates to the field of titanium slag furnace equipment, in particular to a degassing device for a closed circulating water system of a titanium slag furnace. Background Art

[0002] In existing technology, degassing devices are crucial components of closed-loop water circulation systems for titanium slag furnaces. They require high degassing efficiency, high safety and reliability, and easy maintenance. During normal operation, these systems generate gas within the pipes. Excessive gas can accumulate in the upper pipes, impacting the water pressure stability within the pipes and ultimately shortening the service life of the titanium slag furnace equipment. Utility Model Content

[0003] The purpose of the utility model is to provide a degassing device for a closed circulating water system of a titanium slag furnace in order to address the above-mentioned deficiencies, thereby improving the degassing rate of the closed circulating water system of the titanium slag furnace and ensuring the overall stability of the closed circulating water system of the titanium slag furnace.

[0004] The technical solution of the utility model is: a degassing device for a closed circulating water system of a titanium slag furnace, including a closed circulating water pipeline, which is composed of a small-diameter pipeline changing to a large-diameter pipeline along the flow direction, a water distributor on the small-diameter pipeline, and a water distributor and a degassing tank connected in sequence on the large-diameter pipeline. It is characterized in that a first composite exhaust valve is arranged on the large-diameter pipeline at the place where the small-diameter pipeline changes to the large-diameter pipeline, and a second composite exhaust valve is arranged on the degassing tank.

[0005] The advantages of this utility model are: 1. Higher degassing efficiency. In the past, the degassing efficiency of the closed circulating water system of the titanium slag furnace was approximately 80%. This device increases the degassing efficiency of the entire set of equipment to 90% to 95%. 2. Improves the stability of the water pressure in the pipeline. This device can quickly remove the gas generated during normal operation in the pipeline, reducing the accumulation of gas in the pipeline. 3. Improves the service life of the equipment in the entire closed circulating water system of the titanium slag furnace. If there are accidents such as power outages and pump stoppages, negative pressure will appear in some pipelines. At this time, the exhaust valve reserved in this device can take in a large amount of air to ensure the safety of the equipment. 4. Easy maintenance. The newly added composite exhaust valve in this device can be easily disassembled from the closed circulating system of the titanium slag furnace for maintenance.

[0006] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0007] Figure 1 This is a simplified structural diagram of the utility model. DETAILED DESCRIPTION

[0008] See also Figure 1The names of the parts are as follows: small diameter pipeline 1, large diameter pipeline 2, water distributor 3, second water distributor 4, degassing tank 5, first compound exhaust valve 6, second compound exhaust valve 7, reducing pipe 8, flow direction 9.

[0009] See also Figure 1 The degassing device of the closed circulating water system of the titanium slag furnace includes a closed circulating water pipeline. The pipeline is composed of a small-diameter pipeline 1 that changes to a large-diameter pipeline 2 in the flow direction. There is a water distributor 3 on the small-diameter pipeline 1, and a second water distributor 4 and a degassing tank 5 connected in sequence on the large-diameter pipeline 2. A first composite exhaust valve 6 is provided on the large-diameter pipeline 2 where the small-diameter pipeline 1 changes to the large-diameter pipeline 2, that is, it is provided at the rear of the reducer 8. When the gas passes through the reducer, the pressure in the pipeline changes, causing the gas dissolved in the water to overflow. The first composite exhaust valve 6 is provided here to discharge the gas in the system in time to prevent the gas from accumulating too much in the pipeline and affecting the overall stability of the system. A second composite exhaust valve 7 is provided on the degassing tank 5, which is the highest point in the system. The installation of the second composite exhaust valve 7 here is conducive to discharging the gas accumulated in the system and improving the degassing effect of the entire system. By adding a first composite exhaust valve 6 to the rear section of the reducer 8 and a second composite exhaust valve 7 to the top of the degassing tank 5, the addition of two composite exhaust valves improves the degassing efficiency of the titanium slag furnace's closed circulating water system and enhances the stability of the water pressure within the pipeline, thus resolving the low degassing efficiency previously associated with titanium slag furnaces. This device has been applied in titanium slag furnace projects, significantly enhancing degassing effectiveness.

[0010] The working principle of a compound exhaust valve is that gas within the system moves upward along the pipeline and eventually converges at the highest point in the system. The compound exhaust valve is generally installed at this point. When gas enters the upper portion of the compound exhaust valve, as the gas inside the valve increases and the pressure rises, the gas causes the water level inside the valve to drop. The internal float drops along with the water level, allowing the gas to be discharged through the exhaust hole. Once the gas is exhausted, the water level rises, the internal float rises, and the exhaust hole closes. Conversely, when the internal pressure is negative, the gas in the air enters the compound exhaust valve cavity through the exhaust hole, ensuring stable pressure within the system.

[0011] The above description is only a specific implementation of the present invention, and various examples do not limit the essential content of the present invention.
