The detection instrument can only ensure the accuracy and reliability of the detection data within a specific temperature range. The high temperature of the waste gas will cause measurement deviation of the detection instrument, reduce its sensitivity, and even cause damage to the internal precision components, seriously affecting the normal development of the detection work. The existing waste gas cooling device has unsatisfactory cooling effect on the waste gas with high water content, and problems such as condensate accumulation and pipeline blockage are prone to occur, which is difficult to meet the current requirements for efficient and stable cooling of waste gas, and affects the subsequent detection accuracy.

[0012] In the diagram: 1 Outer cylinder, 2 Inner cylinder, 3 Air inlet pipe, 4 Air outlet pipe, 5 Water inlet pipe, 6 Water outlet pipe, 7 Drain pipe, 8 Water seal pipe, 9 Drain valve, 10 Pall ring packing. Detailed Implementation
[0013] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0014] like Figure 1 As shown, this embodiment of a sleeve-type exhaust gas cooling device includes an inner cylinder 2, through which an outer cylinder 1 passes, both arranged coaxially, with the top and bottom of the inner cylinder 2 protruding from the outer cylinder 1. The inner cavity of the inner cylinder 2 serves as an exhaust gas flow channel. The bottom of the inner cylinder 2 is connected to an inlet pipe 3, and the top of the inner cylinder 2 is connected to an outlet pipe 4. The inlet pipe 3 and the outlet pipe 4 are respectively connected to the exhaust gas flow channel. A cooling water channel is formed between the inner wall of the outer cylinder 1 and the outer wall of the inner cylinder 2. One end of the inlet pipe 5 is connected to the top of the outer cylinder 1, and one end of the outlet pipe 6 is connected to the bottom of the outer cylinder 1. The inlet pipe 5 and the outlet pipe 6 are respectively connected to the cooling water channel, and the other ends of the inlet pipe 5 and the outlet pipe 6 are respectively connected to a cooling water supply device. The inner cavity of the inner cylinder 2 is filled with Pall ring packing. When exhaust gas with a high moisture content enters the inner cylinder from bottom to top through the inlet, the exhaust gas rises through the Pall ring packing and exchanges heat with the inner cylinder wall and the Pall ring packing 10. At this time, cooling water enters the cooling water channel through the inlet pipe. The cooling water flowing downwards in the cooling water channel absorbs the heat transferred from the inner cylinder, causing the exhaust gas temperature to gradually decrease. The condensate produced during the cooling process flows down the inner cylinder wall. The cooled exhaust gas is discharged from the outlet pipe for subsequent treatment or testing operations, and the cooled water after heat exchange flows into the cooling water supply device through the outlet pipe.
[0015] The aforementioned Pall ring packing has multiple inward or outward extending blades on its annular surface. This structure can effectively increase the turbulence of the exhaust gas during the flow process, allowing the exhaust gas to have more sufficient contact with the Pall ring packing, greatly improving the heat transfer efficiency, and thus significantly enhancing the cooling effect.
[0016] The inner cylinder bottom end is provided with a discharge port, the discharge port is connected with a discharge pipe 7, and the discharge pipe 7 is provided with a discharge valve 9. The discharge pipe 7 is connected with a U-shaped water seal pipe 8, and the water seal pipe 8 stores a certain amount of water. The water seal pipe can effectively prevent outside air from flowing into the inner cylinder, thereby avoiding interference with waste gas composition detection. After the equipment is operated for a period of time, if the inner cylinder needs to be cleaned and maintained, the waste gas supply can be stopped first, then the discharge valve is opened, and the condensed water and impurities in the inner cylinder are discharged. Due to the water sealing effect of the water seal pipe, waste gas can be effectively prevented from leaking to the outside environment. After cleaning, the discharge pipe valve is closed, and the equipment can be restored to normal operation.
[0017] The outer cylinder is wrapped with a cold insulation layer, which can be made of high-quality cold insulation materials such as polyurethane foam and rock wool. The cold insulation layer reduces the heat exchange between the outer cylinder and the outside environment, effectively reduces the heat loss of the cooling water during circulation, maintains the low temperature of the cooling water, improves the cooling efficiency and reduces energy consumption.
[0018] The application is convenient to operate, and the temperature of the waste gas with high water content is reduced by circulating cooling water, thereby avoiding the influence of high-heat waste gas on the environment and the harm to the health of workers, providing good conditions for subsequent treatment and detection of waste gas.
[0019] In addition to the above embodiments, the utility model also includes other implementation manners, and any technical solution formed by equivalent transformation or equivalent replacement shall fall within the protection scope of the utility model claim.
