Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, specifically to an automatic analysis device for condensate recovery. Background Technology

[0002] The main drying methods for dicalcium phosphate are airflow drying and steam drying. Airflow drying uses coal as a heat source, which is neither environmentally friendly nor cost-effective. For dicalcium phosphate production enterprises with sulfuric acid production sections, using saturated steam generated from sulfuric acid for drying the finished product is a better choice. However, saturated steam from sulfuric acid contains a certain concentration of sulfur dioxide gas. Therefore, after drying dicalcium phosphate with this steam, a large amount of condensate will be generated during cooling. Undoubtedly, the sulfur dioxide dissolved in the steam will continue to dissolve in the condensate. This cooling water is a strong acid and has a certain degree of corrosiveness, posing a certain hazard to human health and equipment. The traditional approach is to analyze the water quality to determine whether the condensate is up to standard and can be directly recycled. However, this method is inefficient and cannot provide real-time feedback on the quality of the condensate. Furthermore, errors can occur due to manual operation, resulting in low efficiency in condensate recycling. Summary of the Invention

[0003] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide an automatic analysis device for condensate recovery.

[0004] According to the technical solution provided in the embodiments of this application, an automatic analysis device for condensate recovery includes a housing with a condensate inlet pipe connected to a condensate collection tank inside the housing. The outlet pipe of the condensate collection tank is connected to a condensate detection tank located inside the housing via a switch valve. A level gauge and a conductivity meter installed on the condensate detection tank work in concert with a three-way valve on the condensate outlet pipe of the condensate detection tank through a control system to achieve real-time detection, recovery, and recycling of condensate.

[0005] Furthermore, the condensate detection tank is located directly below the condensate collection tank, which facilitates the flow of condensate from the condensate collection tank into the condensate detection tank.

[0006] Furthermore, cooling water pipes are wound around the outer end faces of the condensate collection tank and the condensate detection tank to achieve tank cooling.

[0007] Furthermore, the enclosure is equipped with a circulating water cooling device, and the cooling water pipes are connected to the circulating water cooling device, so that the cooling water can be recycled and energy is saved.

[0008] Furthermore, the circulating water cooling device includes a cooling water tank, cooling tower plates, and circulating water inlet pipes. Several cooling tower plates are placed sequentially from top to bottom in the upper part of the cooling water tank. The circulating water inlet pipes are fixed on the top surface of the cooling water tank above the cooling tower plates. The circulating water cooling device is connected to the cooling water pipes through the circulating water inlet pipes. The cooling tower plates are conical plates with multiple holes.

[0009] Furthermore, both the condensate collection tank and the condensate detection tank are equipped with thermometers to monitor the temperature inside the tanks in real time.

[0010] Furthermore, the enclosure is equipped with heat dissipation holes and a control panel to facilitate heat dissipation and ease of operation.

[0011] In summary, the beneficial effects of this application are as follows: This device has the following advantages: 1. The device in this application uses advanced sensing and intelligent control technology through a control system to monitor and analyze the water quality of condensate in real time, determine the recycling and reprocessing of condensate, which can greatly reduce the time spent on manual detection and judgment, greatly improve production efficiency, and provide strong support for the efficient production and operation of enterprises. 2. The device of this application has cooling water pipes on the outer end face of both the condensate collection tank and the condensate detection tank, which can effectively reduce the temperature of the condensate and prevent sulfuric acid water from splashing out and corroding the equipment; 3. The device in this application is equipped with a circulating water cooling system, which can greatly reduce water consumption and lower operating costs. Attached Figure Description

Detailed Implementation

[0014] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0015] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0016] An automatic analysis device for condensate recovery, such as Figure 1 As shown, the upper part of the box 1 is provided with a condensate inlet pipe 2, the upper surface of the box 1 is provided with heat dissipation holes, the front surface is provided with a control panel, and the bottom part of the box 1 is provided with a three-way valve 44. like Figure 1 and Figure 2 As shown, the condensate inlet pipe 2 passing through the box 1 is connected to the upper part of the condensate collection tank 3 inside the box 1. The box 1 directly below the condensate collection tank 3 is equipped with a condensate detection tank 4, and the lower end face of the condensate collection tank 3 is equipped with a water outlet pipe. The water outlet pipe is equipped with a switch valve connected to the condensate detection tank 4. In this way, the condensate in the condensate collection tank 3 can flow into the condensate detection tank 4 by the gravity of the water, without the need for external power, thus saving energy consumption. A level gauge 41 and a conductivity meter 42 are installed in the condensate detection tank 4 to detect the level and quality of the condensate in the condensate detection tank 4. The condensate outlet pipe of the condensate detection tank 4 passes through the box body 1 and is connected to the three-way valve 44. A serpentine cooling water pipe 5 is wound around both the condensate collection tank 3 and the condensate detection tank 4, and the cooling water pipes 5 on the condensate collection tank 3 and the condensate detection tank 4 are connected to the circulating water inlet pipe 63 at the upper part of the circulating water cooling device 6. like Figure 3 and Figure 4 As shown, the circulating water inlet pipe 63 is fixed on the upper surface of the cooling water tank 61, and the outlet of the circulating water inlet pipe 63 is located directly above the cooling tower plate 62. The three cooling tower plates 62 are fixed in the upper part of the cooling water tank 61 from top to bottom. The cooling tower plate 62 is a conical plate with holes. The cooling water tank 61 below the cooling tower plate 62 is provided with an inlet, and the cooling water tank 61 is provided with an outlet at the lower end. A water pump is provided at the outlet to facilitate pumping the water in the cooling water tank 61 into the cooling water pipe 5 to cool the condensate collection tank 3 and the condensate detection tank 4.

[0017] Since both the condensate collection tank 3 and the condensate detection tank 4 are equipped with thermometers, the temperature inside the tanks can be monitored in real time.

[0018] The thermometer, switch valve, level gauge 41, conductivity meter 42, three-way valve 44, water pump, etc. on the condensate collection tank 3 and condensate detection tank 4 are all connected to the control system.

[0019] In use, the condensate inlet pipe 2 is connected to the steam cooling pipe in industrial production. The steam is cooled into water and flows directly into the condensate collection tank 3. At this time, the control system opens the switch valve on the outlet pipe of the condensate collection tank 3, allowing the condensate in the condensate collection tank 3 to flow into the condensate detection tank 4 due to its own gravity. When the level gauge 41 in the condensate detection tank 4 detects that the liquid level in the tank exceeds 50%, the switch valve is closed. At this time, since the conductivity meter 42 can detect the ion status in the tank in real time, when the ion concentration in the tank is greater than the recovery standard, the condensate in this tank is returned to the boiler deaerator to remove acidic gases from the condensate through the control of the three-way valve 44. When the ion concentration in the tank is lower than the recovery standard, the condensate in this tank is recovered and reused through the control of the three-way valve 44, realizing a cycle.

[0020] During the collection and testing of condensate, if the temperature inside the tank is detected to be greater than 50 degrees Celsius, the water pump on the outlet of the cooling water tank 61 is turned on to pump the cooling water in the cooling water tank 61 into the cooling water pipe 5. Since the cooling water pipe 5 is wrapped around the outer end face of the condensate detection tank 4 and the condensate collection tank 3, the tank body can be cooled down, thereby reducing the temperature inside the tank and causing the steam to completely condense into liquid for easy testing. The cooled water will flow through the circulating water inlet pipe 63 at the upper part of the cooling water tank 61 to the cooling tower plate 62. The conical design of the cooling tower plate 62 can increase the contact area between water and air to achieve cooling. Finally, the cooled water flows back into the cooling water tank 61 and can be circulated back into the cooling water pipe 5 by the water pump to cool the condensate detection tank 4 and the condensate collection tank 3.

[0021] The above description is merely a preferred embodiment of this application and an explanation of the technical principles and solutions employed. Furthermore, the scope of the invention involved in this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above-described features with (but not limited to) technical features with similar functions disclosed in this application.
