Pure steam is produced by a steam generator and then transported to the end-user by the system. The quality of pure steam affects the quality and safety of back-end process products. Therefore, it is very important to ensure the quality of pure steam. Sampling devices are generally set up at multiple locations to sample and test pure steam at different locations.

[0003] In the related art, the pure steam sampling device includes a vertically arranged cooler and a cold water tank, and the top of the cooler is connected to the cold water tank through a pipeline. A pure steam inlet pipe is provided at the top of the cooler, and a sampling pipeline is connected to the bottom of the cooler. In actual use, the staff introduces pure steam into the inlet pipe at the top of the cooler, and the pure steam flows from top to bottom along the cooler for cooling.

[0004] With respect to the above-mentioned related technologies, the cooling efficiency of the vertically arranged cooler is low, and the staff may be scalded by the pure steam flowing out of the sampling pipeline when taking samples. Summary of the invention

[0005] In order to improve the cooling efficiency and safety of the sampling equipment, the present application provides a pure steam sampling vehicle.

[0008] By adopting the above technical solution, in actual work, the liquid pump allows the coolant to circulate continuously in the cooling passage, and the staff introduces pure steam into the condenser through the inlet pipe. The pure steam and the coolant exchange heat, and the pure steam condenses into liquid and flows out from the outlet pipe. The staff opens the sampling valve, and the condensed pure steam flows out. The horizontally arranged condenser helps to reduce the possibility of pure steam flowing out of the outlet pipe due to gravity. The staff can ensure that the condensed pure steam gathers at the outlet pipe by delaying the opening of the sampling valve, thereby helping to reduce the possibility of pure steam gas flowing out of the outlet pipe. At the same time, the horizontally arranged condenser helps to prolong the time that the pure steam stays in the condenser, thereby helping to improve the working efficiency of the condenser.

[0009] Preferably, a shell is provided on the frame, and the shell includes a door panel that can be opened or locked.

This method can further reduce the possibility of staff being scalded by pure steam. The excess condensed pure steam falls into the water collection tank through the porous plate, which helps to reduce the pollution to the production workshop.

[0013] Preferably, a discharge pipe is connected to the water collecting tank, and a discharge valve is connected between the discharge pipe and the water collecting tank.

[0018] By adopting the above technical solution, the staff can replace the coolant in the cooling box through the replenishing pipe and the drain pipe, which helps to improve the working efficiency of the condenser.

[0019] Preferably, a temperature meter is provided between the condenser and the cooling box.

[0020] By adopting the above technical solution, the staff can monitor the temperature of the coolant flowing out of the condenser and replace the coolant in time, which helps to improve the cooling efficiency of the condenser.

A shell 7 is also covered on the outer side of the frame 1, and a door panel 71 is arranged on both sides of the width direction of the shell 7. Any door panel 71 is hinged to the frame 1, and any door panel 71 is provided with a locking device to lock the door panel 71 with the shell 7. The locking device can be a bolt, a nut, a metal buckle or a magnet. An open port 72 is also opened on one side of the shell 7 in the length direction, and a sampling tube 3 is arranged on the condenser 2 in communication. The sampling tube 3 is arranged vertically, and the sampling tube 3 passes through the shell 7 along its axial direction and is arranged in the open port 72. A porous plate 721 is arranged at the lower side of the open port 72, and the porous plate 721 is fixed on the shell 7. A water collecting tank 74 is also arranged at the lower side of the porous plate 721. Universal wheels 9 are also fixed to the lower side of the housing 7 , and four universal wheels 9 are provided in this embodiment.

[0035] See also Figure 1-2The condenser 2 includes a cooling tube 21, and the axial direction of the cooling tube 21 is horizontally arranged. A plurality of heat exchange tubes 24 are evenly spaced in the cooling tube 21, and the axial direction of any heat exchange tube 24 is parallel to the axial direction of the cooling tube 21. An inner tube sheet 26 is respectively arranged at both ends of the axial direction of the cooling tube 21, and a sealed cooling cavity is formed between the two inner tube sheets 26 and the inner wall of the cooling tube 21. An outer tube sheet 25 is arranged on the side of the two inner tube sheets 26 that are away from each other. Any end of any heat exchange tube 24 passes through the outer tube sheet 25 and the inner tube sheet 26 of the corresponding side in sequence along its axial direction. The horizontally arranged condenser 2 helps to reduce the possibility of pure steam flowing out of the outlet pipe 272 due to gravity, and at the same time helps to prolong the time that pure steam stays in the condenser 2, thereby helping to improve the working efficiency of the condenser 2. The double tube sheet helps to further isolate the coolant and pure steam, reduce the occurrence of mixing of pure steam and coolant, and thus ensure the purity of the sampling.

[0036] The two outer tube sheets 25 are provided with heads 27 on the sides facing away from each other. An inlet pipe 271 is connected to the head 27 on one side, and the inlet pipe 271 passes through the shell 7 along its axial direction, so that the staff can connect the inlet pipe 271 with the pure steam generation or transmission equipment and operate the pure steam sampling vehicle.

[0037] See also Figure 1-Figure 3 , an outlet pipe 272 is also connected to the end cap 27 on the side of the cooling pipe 21 that is away from the inlet pipe 271 in the axial direction, and the outlet pipe 272 is vertically arranged. The sampling pipe 3 is connected to the lower side of the outlet pipe 272, and the sampling pipe 3 is coaxially fixed with the outlet pipe 272. A sampling valve 31 is connected to the lower side of the sampling pipe 3, and the sampling valve 31 is located in the open port 72. The inlet pipe 271, the end cap 27, the heat exchange pipe 24 and the outlet pipe 272 form a steam passage. In actual use, the staff introduces pure steam into the end cap 27 through the inlet pipe 271, and the pure steam exchanges heat with the coolant in the cooling pipe 21 through the heat exchange pipe 24. The pure steam condenses and flows into the end cap 27 on the side where the outlet pipe 272 is provided, and flows into the sampling pipe 3 through the outlet pipe 272. The staff places the sampling cup on the porous plate 721. After a period of time after pure steam is introduced, the staff opens the sampling valve 31, and the condensed pure steam drips into the sampling cup. In this way, it is ensured that the condensed pure steam is gathered at the outlet pipe 272, which helps to reduce the possibility of pure steam gas flowing out of the outlet pipe 272.

[0038] The cooling pipe 21 is connected and fixed with a liquid inlet pipe 22 and a liquid outlet pipe 23, and both the liquid inlet pipe 22 and the liquid outlet pipe 23 are arranged vertically.

The liquid inlet pipe 22 and the liquid outlet pipe 23 are respectively located at the two ends of the axial direction of the cooling pipe 21. The liquid inlet pipe 22, the cooling pipe 21 and the liquid outlet pipe 23 form a cooling passage. The lower side of the liquid inlet pipe 22 is connected with a liquid pump 6, the liquid outlet of the liquid pump 6 is connected to the liquid inlet pipe 22, and the liquid inlet of the liquid pump 6 is connected to the cooling box 4. A pressure gauge 5 is also arranged on the liquid inlet pipe 22, and the sensing part of the pressure gauge 5 is connected to the liquid inlet pipe 22. The staff can monitor the pressure and flow rate of the coolant entering the cooling pipe 21 in real time by monitoring the pressure gauge 5.

[0039] A return pipe 42 is coaxially connected to the liquid outlet pipe 23, and a section of the return pipe 42 away from the liquid outlet pipe 23 is connected to the cooling box 4. A thermometer 43 is fixed between the return pipe 42 and the liquid outlet pipe 23, and the thermometer 43 is a pressure thermometer.

[0040] A liquid infusion pipe 41 is also provided on the upper side of the cooling box 4. The liquid infusion pipe 41 is vertically provided. The upper end of the liquid infusion pipe 41 passes through the housing 7 along its axial direction. The upper end of the liquid infusion pipe 41 is open. A connecting pipe 44 is provided at the bottom of the cooling box 4. A drain pipe 45 is provided at one end of the connecting pipe 44 away from the cooling box 4. A drain valve 46 is provided on the drain pipe 45. The drain valve 46 is a manual ball valve. One end of the drain pipe 45 away from the connecting pipe 44 passes through the housing 7 along its axial direction. One end of the connecting pipe 44 away from the cooling box 4 is also connected to the liquid inlet of the liquid pump 6.

[0041] During the cooling operation, the liquid pump 6 pumps the coolant in the cooling box 4 into the liquid inlet pipe 22, and then into the cooling pipe 21. The coolant flows into the cooling pipe 21 from bottom to top, and then overflows from the cooling pipe 21 from the liquid outlet pipe 23, and returns to the cooling box 4 through the reflux pipe 42. The thermometer 43 facilitates the staff to monitor the temperature of the coolant in real time before it flows out of the condenser tube 2 and returns to the cooling box 4 after the cooling is completed. According to the temperature displayed on the thermometer 43, the staff adds or replaces the coolant through the liquid replenishing pipe 41 and the liquid draining pipe 45, thereby changing the coolant temperature in the cooling box 4, which helps to improve the condensation effect of the condenser tube 2.

The staff can discharge the liquid accumulated in the water collecting tank 74 by opening the discharge valve 81.

[0044] The housing 7 is also provided with a push handle, which is located on the side of the housing 7 in the length direction away from the sampling valve 31. The push handle and the universal wheel 9 facilitate the staff to move the pure steam sampling vehicle.

[0045] The implementation principle of a pure steam sampling vehicle in the embodiment of the present application is as follows: the staff connects the inlet pipe 271 to the pure steam generating device or the transmission pipeline, and the pure steam flows into the heat exchange tube 24 through the one side end cap 27. The liquid pump 6 pumps the coolant in the cooling box 4 into the inlet pipe 22, and the coolant enters the cooling tube 21 from top to bottom, and heat exchange occurs between the coolant in the cooling tube and the pure steam in the heat exchange tube 24. After the pure steam is condensed, it flows along the heat exchange tube 24 into the other side end cap 27, and then flows out from the outlet pipe 272. The staff places the sampling cup on the porous plate 721, opens the sampling valve 31, and the condensed pure steam drips into the sampling cup.
