Description

Technical Field

[0001] The utility model relates to the general field of heat exchange technology, in particular to a wet heat exhaust gas condenser. Background Art

[0002] During heat exchange, the hot and humid waste gas enters from the waste gas inlet of the top head. After heat exchange in the tube, the condensed waste water is discharged from the bottom head by gravity, and the non-condensable gas flows out from the waste gas outlet at the other end of the top head. The circulating cooling water enters from the shell inlet, and after heat exchange, it flows out from the shell outlet. The waste gas inlet and outlet of the top head are separated by a middle partition. Insufficient points in production:

[0003] 1. Due to the high dust content in the exhaust gas, the tubes in the tube bundle are easily clogged. Once the clog is serious, the equipment cannot achieve the condensation and heat exchange function, and the condenser cannot be cleaned online. It is necessary to stop production and open the holes for manual cleaning;

[0004] 2. After the humid and hot exhaust gas is condensed, the volume flow rate is significantly reduced. The partition is in the middle position, which will cause the gas flow rate to be too fast and affect the heat exchange effect. Utility Model Content

[0005] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art and to provide a humid heat exhaust gas condenser which can solve the problem that the condenser needs to be manually cleaned only after production is stopped and holes are punched, and the partition is in the middle position which affects the heat exchange effect.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a humid heat exhaust gas condenser, comprising tubes;

[0007] A cleaning assembly for facilitating cleaning of the array tubes is arranged in the array tubes, the cleaning assembly comprises a flushing pipe interface and a flushing pipe, the flushing pipe interface is adhered to the array tubes, and a part of the flushing pipe is arranged outside the array tubes, and the flushing pipe is welded to the surface of the flushing pipe interface;

[0008] A partition is welded inside the tube array, which divides the inside of the tube array into two parts, namely the air inlet cavity and the air outlet cavity. The two ends of the flushing pipe are respectively inside the two parts of the tube array divided by the partition, and the interface between the flushing pipe and the partition is connected by welding.

[0009] Preferably, a cylinder is mounted on the lower surface of the tube array by screws.

[0010] Preferably, a wet hot exhaust gas inlet pipe is welded to the surface of the tube array, and an exhaust gas outlet pipe is welded to the surface of the tube array.

Clean water is injected into the flushing pipe interface. After diversion through the flushing pipe, the tubes can be directly cleaned to avoid blockage of the tubes in the tube bundle caused by excessive dust in the exhaust gas.

[0025] See also Figure 1-2 , the utility model provides a technical solution: a humid heat exhaust gas condenser, comprising a tube array 10;

[0026] A cleaning assembly for facilitating cleaning of the array tubes is arranged in the array tubes 10, and the cleaning assembly includes a flushing pipe interface 2 and a flushing pipe 6, the flushing pipe interface 2 is adhered to the array tubes 10, and a part of it is arranged outside the array tubes 10, and the flushing pipe 6 is welded to the surface of the flushing pipe interface 2;

[0027] A partition 5 is welded inside the tube array 10, which divides the interior of the tube array 10 into two parts, namely an air inlet chamber and an air outlet chamber. The two ends of the flushing pipe 6 are respectively inside the two parts of the tube array 10 divided by the partition 5, and the interface between the flushing pipe 6 and the partition 5 is connected by welding.

[0028] The cylinder 7 is mounted on the lower surface of the tube array 10 by screws.

[0029] A wet hot exhaust gas inlet pipe 1 is welded to the surface of the tube array 10 , and an exhaust gas outlet pipe 3 is welded to the surface of the tube array 10 .

[0030] The wet hot exhaust gas inlet pipe 1 and the exhaust gas outlet pipe 3 are symmetrically distributed along the tube array 10 .

[0031] Two inspection pipes 4 are welded on the surface of the tube array 10 , and the two inspection pipes 4 are symmetrically distributed along the tube array 10 .

[0032] Covers 9 are screwed onto the surfaces of the two inspection pipes 4 , and handles 8 are welded onto the backs of the two cover 9 .

[0033] It should be noted that the partition 5 in the existing hot and humid exhaust gas condensation pipe is arranged inside the tube array 10. Figure 1 As shown, the tubes 10 are arranged in the center; and the partition 5 of the utility model is arranged in the position as shown Figure 2 As shown, the partition plate 5 is located closer to the exhaust gas outlet pipe 3.

[0034] When heat exchange is performed, the wet hot exhaust gas enters the interior of the tube array 10 through the wet hot exhaust gas inlet pipe 1 , and after heat exchange in the tube flow, the non-condensable gas flows out of the interior of the tube array 10 from the exhaust gas outlet pipe 3 .

[0035] When it is necessary to clean the array tube 10, first, clean water is injected into the inside of the flushing pipe interface 2. The clean water flows through the flushing pipe interface 2 to the inside of the flushing pipe 6 and then flows into the two parts of the array tube 10 divided by the partition 5 to clean the inside of the array tube 10.

[0036] In the sludge thermal drying process, after the wet sludge is heated in the dryer (indirect heat exchange with the heat source), the moisture is carried out of the dryer along with the carrier gas. Since the evaporated hot and humid exhaust gas has a high temperature and humidity and contains some dust, in order to facilitate pipeline transportation to the terminal device for collection and treatment, we need to use a condenser to cool and condense the hot and humid exhaust gas.

[0037] By providing a flushing pipe interface 2 and a flushing pipe 6 with a diversion function in the cleaning component, clean water is injected into the flushing pipe interface 2. After diversion through the flushing pipe 6, the tube array 10 can be directly cleaned to avoid clogging of the tube array in the tube bundle due to excessive dust in the exhaust gas. In addition, there is no need to stop production and drill holes during cleaning, making it more convenient to clean the tube array 10.

[0038] By setting the spacer 5 with offset position, as Figure 2 As shown, compared to Figure 1 The position of the middle partition 5 is adjusted to increase the volume of the air inlet cavity, reduce the gas flow rate, and improve the condensation effect of the condenser on the wet and hot exhaust gas.

[0039] Working principle: When heat exchange is performed, the hot and humid exhaust gas enters the interior of the tube array 10 through the hot and humid exhaust gas inlet pipe 1. After heat exchange in the tube flow, the non-condensable gas flows out of the interior of the tube array 10 from the exhaust gas outlet pipe 3.

[0040] When it is necessary to clean the array of tubes 10 , first, clean water is injected into the flushing pipe interface 2 . The clean water flows through the flushing pipe interface 2 to the inside of the flushing pipe 6 , and then flows into the two parts of the array of tubes 10 divided by the partition 5 .

[0041] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
