Description

Technical Field

[0001] The invention relates to the field of condensate collection in chimneys, and in particular to a condensate collection device inside a titanium steel chimney. Background Art

[0002] The hazards of condensate in chimneys are as follows: 1. Corrosive damage Acid corrosion: Sulfur oxides in flue gas ( ), nitrogen oxides ( ) combines with water vapor to form strong acids such as sulfuric acid and nitric acid, which corrode the inner wall of the metal chimney, causing the material to become thinner, perforated, and even structural failure.

[0003] Material Degradation: Concrete or brick chimneys may suffer chemical attack from acidic liquid penetration, reducing durability.

[0004] 2. Structural damage risk Liquid load: Condensate accumulation increases the weight of the chimney, which may cause deformation or cracks in the long term; ice expansion in winter further increases structural pressure.

[0005] Thermal stress cracks: The alternating action of condensate and high-temperature flue gas causes the material to expand and contract, resulting in fatigue cracks.

[0006] 3. Decreased emission efficiency Airflow obstruction: Liquid accumulation hinders the flow of flue gases, increases back pressure, reduces the efficiency of combustion equipment (such as boilers), wastes fuel, and may cause the retention of harmful gases such as carbon monoxide.

[0007] Temperature reduction: Condensation releases latent heat, which reduces chimney draft, affects smoke exhaust effects, and in severe cases causes smoke backflow.

[0008] 4. Environmental pollution Toxic leaks: Leakage of condensate containing acidic substances or heavy metals may contaminate soil and groundwater, violate environmental regulations, and lead to legal disputes.

[0009] Secondary emissions: When accumulated liquid evaporates, pollutants may be released again, increasing the difficulty of air treatment.

[0010] 5. Increased maintenance costs Frequent cleaning: accumulated fluid and corrosion products need to be removed regularly, increasing maintenance costs.

[0011] Equipment replacement: Corrosion-damaged components (e.g., linings, sensors) need to be replaced more frequently, increasing operating expenses.

[0012] Therefore, a chimney internal condensate collecting device is urgently needed. Summary of the Invention

[0031] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0032] The present invention provides a device for collecting condensate inside a titanium steel chimney. Figures 1-6 As shown, the titanium steel chimney is provided with multiple chimney platforms 1 spaced apart from each other, and the condensate collecting device inside the titanium steel chimney includes: A condensate collecting tank 2, wherein the condensate collecting tank 2 is installed inside the titanium steel chimney; A drain pipe 3, wherein the drain pipe 3 is installed on the chimney inner wall 6 of the titanium steel chimney and is connected to the condensate collecting tank 2; The chimney drain pipe 5 is arranged at the bottom of the titanium steel chimney.

[0033] Preferably, a flue drainage baffle 4 is provided above the water inlet of the chimney drain pipe 5 .

[0034] Preferably, the condensate collecting tank 2 is divided into several components, and the several components are spliced ​​on site.

[0035] Preferably, the mounting assembly is installed at an inclination angle of 5°.

[0036] Preferably, a titanium plate connector 21 is provided at an angle of 8° along the circumferential direction of the titanium steel chimney; Preferably, the condensate collecting tank 2 is also made of titanium plate, and the drain pipe 3 is also made of titanium plate.

[0037] Preferably, the drain pipe 3 is formed by the chimney inner wall 6, two titanium plates 1 31 and one titanium plate 2 32.

[0038] The beneficial effects of the above technical solution are: This device collects condensate from the chimney's inner wall and diverts it to the chimney's base for discharge. Made of pure titanium, it can be installed inside a titanium steel chimney, eliminating the need for an external drain pipe. It offers strong corrosion and expansion resistance, effectively collecting condensate and rainwater from the chimney and discharging it to the chimney's base for recovery. The condensate collection tank 2 provided inside the titanium steel chimney can intercept the liquid water formed by the condensation of the flue gas, thereby preventing the condensate from flowing directly along the inner wall of the chimney and causing corrosion of the inner wall.

[0039] The collection tank is installed at an inclination angle of 5°, using gravity to accelerate the flow of condensate and prevent liquid accumulation; the drain pipe is surrounded by titanium plates to form a diversion channel, ensuring that the liquid quickly flows into the bottom drain pipe to reduce the risk of corrosion.

[0040] The condensate collection tank 2 and the drain pipe 3 are both made of titanium plates. Titanium has strong corrosion resistance, especially in the flue gas. 、 Compared to ordinary steel, titanium can extend equipment life and reduce maintenance costs. Titanium can maintain stable performance in high-temperature and high-humidity flue gas environments, avoiding failures such as collection tank damage and drainage pipe blockage caused by material corrosion.

[0041] The condensate collecting tank 2 is assembled on site from several components, which is convenient for transportation and installation, and does not require lifting of the entire piece.

[0042] Titanium plate connectors are set every 8° along the circumference of the chimney to firmly connect the collection tank to the inner wall of the chimney, enhance the vibration resistance (such as shaking caused by flue gas flow) and prevent the collection tank from falling off.

[0043] Example 2, based on Example 1, further includes: The first collecting device is used to collect the current flue gas parameters at the flue gas inlet of the titanium steel chimney, including: flue gas temperature and flue gas moisture content; The second collecting device is used to collect the condensate collected by the condensate collecting device; The third collecting device is used to collect the flue gas parameters at the chimney outlet of the titanium steel chimney; A chimney air intake flow control device, wherein the chimney air intake flow control device is electrically connected to the first acquisition module, the second acquisition module, the third acquisition device, and the early warning device respectively; the flue gas intake flow control device controls the operation of the flue gas flow regulating device and the early warning device based on the first acquisition device, the second acquisition device, and the third acquisition device; the flue gas flow regulating device is used to regulate the flue gas flow at the flue gas inlet of the titanium steel chimney.

[0044] The chimney air inlet flow control device includes: A first acquisition module: used to acquire data collected by the first acquisition device, the second acquisition device, and the third acquisition device; The second acquisition module is used to obtain the target air intake flow range of the current titanium steel chimney corresponding to the current flue gas exhaust demand, and to obtain the maximum allowable condensation amount per unit time of the current condensing device; The first control module is used to control the actual air intake flow rate of the current titanium steel chimney to be the first flow rate (selected according to the preset flow rate interval) within the target air intake flow rate range for a first preset time period, and determine the detection results of the first collection device and the third collection device during each first preset time period; A first calculation module is configured to periodically calculate a first ratio of an actual amount of condensation per unit time of flue gas to a theoretical amount of condensation per unit time; the actual amount of condensation per unit time of flue gas is determined based on the amount of condensate collected per unit time, and the theoretical amount of condensation per unit time of flue gas is calculated based on a condensation per unit time model; when the first ratio is less than a preset ratio, the early warning device issues an alarm; A second calculation module is used to calculate the first unit time condensation amount corresponding to each first flow rate based on the detection results of the first collection device and the third collection device during each first preset time period and a unit time condensation amount model (which can use an existing model or the following model); A third calculation module is used to determine the actual evaluation value of each first flow rate based on the first unit time condensation amount corresponding to each first flow rate and the first ratio within the second preset time period before the current time; Determination module: used to determine the average value of the three smallest actual evaluation values ​​whose actual evaluation values ​​are greater than the preset evaluation values ​​as the target flow rate; The second control module is used to control the actual air intake flow rate of the current titanium steel chimney to the target flow rate for continuous smoke exhaust during the current smoke exhaust operation of the current smoke producing equipment.

[0045] The third calculation module is based on the following formula: ; The actual evaluation value of the i-th first flow; is the maximum allowable condensation capacity per unit time of the current condensing device; is the condensation amount per unit time corresponding to the i-th first flow rate; n is the total number of first ratios within the second preset time period before the current one; The nth first ratio value among the first ratio values ​​within the second preset time period before the current one; is the kth first ratio value among the first ratio values ​​within a second preset time period before the current one; is the k-1th first ratio value among the first ratio values ​​within the second preset time period before the current one ( The detection time is After the detection time); The total smoke exhaust time of the current smoke-generating equipment during the current operation; is the ideal calculation time interval of the third calculation module (can be based on and determination of exhaust fluctuating state); ; is the condensation amount per unit time corresponding to the i-th first flow rate; is the i-th first flow, is the average moisture content of the flue gas collected by the first collection device during the first preset time period corresponding to the i-th first flow rate; is the average moisture content of the flue gas collected by the third collection device during the first preset time period corresponding to the i-th first flow rate; The saturated moisture content corresponding to the flue gas temperature collected by the third collection device during the first preset time period corresponding to the i-th first flow rate; min represents the minimum value.

[0046] The target air flow rate range is based on the rated exhaust volume of the flue gas generating equipment (e.g., if the boiler's designed exhaust volume is 5,000-5,100 m³ / h at its current secondary operating capacity, the target range could be set at 5,000-5,100 m³ / h). This range is pre-set by the equipment manufacturer or process engineer, along with the maximum allowable flow rate of the titanium steel chimney (limited by chimney diameter and material compressive strength).

[0047] The maximum allowable condensation capacity per unit time for a condensing unit is determined based on the unit's design parameters (e.g., collection tank volume, drain pipe diameter, and drainage pump flow rate). The maximum processing capacity (e.g., 500 L / h) provided by the equipment manufacturer should be considered. A safety margin (e.g., 80% of the design value) should be included to prevent condensate overflow or equipment overload.

[0048] The first preset time length can be 30 minutes; the second preset time length can be 30 minutes; The beneficial effects of the above technical solution are: By collecting inlet / outlet flue gas parameters and condensation volume, combined with the dual constraints of "target flow range + maximum allowable condensation volume", the adaptive flow rate is dynamically screened (for example, according to the exhaust requirements of the smoke-producing equipment, the chimney air intake can be precisely controlled).

[0049] Intelligent optimization: Traverse the target flow range, calculate the condensation effect and system stability under different flow rates, and ultimately lock in the target flow with the "optimal actual evaluation value" to ensure that the smoke exhaust efficiency matches the condensing device load.

[0050] Real-time verification: Compares the ratio of "actual condensation volume" to "theoretical condensation volume" and issues an immediate warning if there is any deviation, allowing for prompt detection of problems such as condensation device blockage and equipment failure (e.g., dust accumulation in the condensate collection tank leading to abnormal collection volume, which can be quickly located and repaired).

[0051] Model-driven: Calculate theoretical condensation capacity based on inlet and outlet flue gas moisture content, temperature, and saturated moisture content, accurately quantify the condensation effect, and provide data support for optimizing the condensation device (such as adjusting the collection tank inclination angle and drain pipe layout).

[0052] Through "multi-flow test + preset time detection", the impact of sudden flow rate changes on the condensing device can be avoided (for example, a large increase in flow rate may cause a sudden surge in condensate, causing backflow of the drain pipe); the actual evaluation value calculation incorporates the "historical ratio fluctuation" factor.

[0053] Full-process monitoring: The data collection device covers the entire process of "inlet-condensation-export", and the flow control device links adjustment and early warning to build a closed-loop control system to reduce unplanned downtime (for example, timely early warning can avoid increased chimney corrosion due to condensation failure).

[0054] The selected target flow rate can reduce the energy consumption of equipment such as fans (such as avoiding redundant power consumption under high flow rates) while meeting the smoke exhaust requirements; combined with dynamic adjustment of condensing efficiency, it can reduce ineffective operation.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
