[0001] The invention relates to the field of condensers, in particular to a corrosion-resistant horizontal shell-and-tube condenser. Background Art

[0002] Horizontal shell and tube condenser is a common heat exchange equipment, mainly used to cool gas or steam and condense it into liquid. Its structural feature is the horizontal layout. There are multiple tubes in the outer shell. The cooling medium flows in the shell, and the gas or steam to be cooled flows in the tube. Its main function is to cool the gas or steam to its saturation temperature and condense it into liquid. It is often used in refrigeration, air conditioning and chemical processes. Horizontal shell and tube condenser plays an important role in many industrial applications and can effectively improve the heat exchange efficiency and the overall performance of the system.

[0003] However, the traditional horizontal shell and tube condenser has the problem that it is not easy to clean the inside of the condenser, which causes dirt, sediment and scale to easily accumulate inside the condenser, which will reduce the heat exchange efficiency and thus cause the system performance to decline. In addition, long-term dirt accumulation and improper cleaning methods may cause corrosion and damage to the condenser material, thereby shortening the service life of the equipment.

[0004] Therefore, those skilled in the art provide a corrosion-resistant horizontal shell and tube condenser to solve the problems raised in the above background technology. Summary of the invention

[0027] (III) Beneficial effects

[0028] The present invention provides a corrosion-resistant horizontal shell-and-tube condenser, which has the following beneficial effects:

[0029] 1. The present invention provides a corrosion-resistant horizontal shell and tube condenser. Compared with the traditional horizontal shell and tube condenser, the tube body used in the horizontal shell and tube condenser consists of a tube cover, an upper tube body and a lower tube body. The tube bodies are fixed together by bolts. Under the action of the tube cover, the fixed position of the tube body is further limited, so that the user can separate the tube body by removing the bolts, thereby maintaining and cleaning the guide plate and the inner wall inside the condenser, thereby more effectively removing dirt and sediments and maintaining heat exchange efficiency. When used in conjunction with the corrosion-resistant material of the tube body itself, it is more effective to prevent corrosion and damage of the condenser, extend the service life of the condenser, thereby improving the corrosion resistance and service life of the condenser, reducing the replacement frequency, and also reducing the difficulty of maintenance, reducing labor and time costs, thereby reducing the overall maintenance cost.

[0030] 2. The present invention provides a corrosion-resistant horizontal shell and tube condenser, which is provided with a delivery pipe. By clamping with a fixed baffle, a first guide plate and a second guide plate, an upper tube body is relatively firmly and tightly restricted on a lower tube body, thereby further limiting and fixing the upper tube body and the lower tube body, and by the cooperation between a fastening nut and a positioning block, the condenser is relatively firmly fixed on the lower tube body, thereby reducing the possibility of the condenser tube body being accidentally opened, so that the condenser is easy to maintain and safe to use, and the user can quickly repair the delivery pipe blocked by dirt and sediment by replacement, thereby reducing the length of time for maintenance and the impact on the condenser.

[0031] 3. The present invention provides a corrosion-resistant horizontal shell and tube condenser, in which the sealing block and the sealing groove are clamped together. Under the action of the rubber sealing block and the rubber sealing strip, the condenser tube body has a structure that is easy to disassemble and has a relatively good sealing effect. Users can reduce the damage to the sealing effect caused by multiple disassembly, maintenance and cleaning by replacing the rubber sealing block and the rubber sealing strip, thereby ensuring the safety of maintenance of the condenser.
