Description

Technical Field

[0001] This utility model relates to the field of phenolic resin production, specifically an energy-saving multi-stage condensation device for phenolic resin production. Background Technology

[0002] Condensation equipment is a crucial component of the phenolic resin production process, primarily used to condense the vapors and volatile substances generated during the reaction into liquids. Existing equipment typically has only one condensation stage, which may result in some volatile organic compounds in the vapor not being completely condensed, thus reducing recovery efficiency and leading to a significant environmental impact from the emitted gases. Furthermore, precise temperature control is difficult to achieve with a single condenser, especially when handling mixtures with different boiling points, potentially resulting in some components not being completely condensed. Additionally, condensing vapor in a single stage consumes relatively large amounts of energy. Therefore, overcoming these technical problems and shortcomings is a key issue that needs to be addressed. Utility Model Content

An intake fan is fixedly installed on the outer wall of the equipment housing, and the exhaust end of the intake fan is connected to the jet chamber. Heat is dissipated through the gas through the heat dissipation pipes, achieving pre-cooling of the steam.

[0008] In the above-mentioned energy-saving multi-stage condensation device for phenolic resin production, the cooling module includes a radiator fixedly installed inside the cooling chamber. One bottom end of the radiator is connected to the air outlet pipe of the heat dissipation pipe, and the bottom of the radiator on the opposite side of the air outlet pipe is connected to the storage tank through a drain pipe.

[0009] In the aforementioned energy-saving multi-stage condensation device for phenolic resin production, the cooling module further includes a water tank fixedly mounted on the side of the equipment housing. The cooling chamber is connected to the water tank via a drainage channel at its bottom. A spray chamber is fixedly mounted at the top of the cooling chamber, and multiple spray heads are installed at the bottom of the spray chamber. The spray chamber is connected to the water tank via a water supply pipe at its end. A liquid pump connected to the water supply pipe is installed inside the water tank.

[0023] See Figures 1-3This embodiment of the energy-saving multi-stage condensation device for phenolic resin production can gradually reduce the temperature of steam through multiple stages, ensuring complete condensation. Compared to a single condensation process, multi-stage condensation improves overall thermal efficiency, reduces cooling water requirements, lowers energy consumption, and helps reduce environmental impact due to reduced cooling water usage. In this embodiment, it mainly includes a housing 1, inside which are interconnected pre-cooling chambers 2 and 3. The pre-cooling chambers 2 and 3 are arranged sequentially from top to bottom, and a connecting hole 7 is provided between them. This ensures a constant pressure inside the 3 cooling chambers and allows for the dissipation of internal heat. A baffle 8 is horizontally installed at the top of the pre-cooling chamber 2 to achieve gas-liquid separation and prevent liquid from spraying onto the interior or other equipment. The housing 1 is also equipped with a liquid recovery storage tank 6 for convenient subsequent liquid recycling.

[0024] To achieve pre-cooling of the steam. See also Figure 2 and Figure 3 In this embodiment, the precooling chamber 2 is equipped with a heat dissipation module 4 for preliminary cooling of steam. The heat dissipation module 4 includes a horizontally arranged heat dissipation pipe 41 inside the precooling chamber 2. The heat dissipation pipe 41 is a mature existing technology and will not be described in detail here. The heat dissipation pipe 41 has a serpentine structure, and its air inlet 42 penetrates through the side wall of the equipment housing 1 and connects to the outside. The serpentine structure of the heat dissipation pipe 41 extends the time the steam spends inside the precooling chamber 2, facilitating cooling of the steam through the heat dissipation pipe 41. A heat dissipation port 43 is opened at the top of the precooling chamber 2, from which hot air is discharged, allowing for connection to other equipment for heat utilization. The heat dissipation module 4 also includes a jet chamber 44 fixedly installed inside the precooling chamber 2 below the heat dissipation pipe 41. Multiple sets of gas nozzles 45 are installed at the top of the jet chamber 44. An intake fan 46 is fixedly installed on the outer wall of the equipment housing 1, and the exhaust end of the intake fan 46 is connected to the jet chamber 44. The intake fan 46 is controlled to blow gas into the pre-cooling chamber 2 and onto the heat dissipation pipe 41 for heat dissipation, thereby achieving pre-cooling of the steam.

[0025] To achieve complete condensation of the steam, in this embodiment, see... Figure 2 and Figure 3The cooling chamber 3 is equipped with a cooling module 5 capable of completely cooling steam. The cooling module 5 includes a radiator 51 fixedly installed inside the cooling chamber 3. The radiator 51 is a mature existing technology and will not be described in detail here. One bottom end of the radiator 51 is connected to the exhaust pipe 52 of the heat dissipation pipe 41. The bottom of the radiator 51 on the opposite side of the exhaust pipe 52 is connected to the storage tank 6 via a drain pipe 60. The cooling module 5 also includes a water tank 53 fixedly installed on the side of the equipment housing 1. The cooling chamber 3 is connected to the water tank 53 via a drain trough 54 at its bottom. A spray chamber 55 is fixedly installed at the top of the cooling chamber 3. Multiple spray heads 56 are installed at the bottom of the spray chamber 55. The spray chamber 55 is connected to the water tank 53 via a water supply pipe 57 at its end. A pump 58 connected to the water supply pipe 57 is installed inside the water tank 53. The liquid pump 58 is controlled to operate, spraying liquid through the spray head 56 onto the radiator 51 to cool the steam inside. The water tank 53 is also equipped with a condenser 59, which is a mature existing technology and will not be described in detail here. The condenser 59 is used to cool the liquid inside the water tank 53.

[0026] The method of using the energy-saving multi-stage condensation device for phenolic resin production of this utility model is as follows: First, steam enters the heat dissipation pipe 41 through the air inlet 42. At this time, the air intake fan 46 is controlled to work, blowing gas into the pre-cooling chamber 2 and onto the heat dissipation pipe 41. The steam is pre-cooled by the gas flow, which facilitates the subsequent cooling operation. During this process, the serpentine structure of the heat dissipation pipe 41 prolongs the time the steam stays in the pre-cooling chamber 2, facilitating the cooling of the steam through the heat dissipation pipe 41, and the hot air is discharged from the heat dissipation outlet 43. The pre-cooled steam enters the radiator 51 through the air outlet 52 of the heat dissipation pipe 41. At this time, the liquid pump 58 is controlled to work, spraying liquid onto the radiator 51 through the water supply pipe 57 and the spray head 56 to cool the steam inside. The steam is condensed into liquid and discharged into the storage tank 6 through the drain pipe 60 for recycling, reducing the emission of harmful substances. During this process, hot air rises and enters the pre-cooling chamber 2 through the connecting hole 7. It then passes through the baffle plate 8 and exits through the heat dissipation port 43 along with the hot air inside the pre-cooling chamber 2, simultaneously maintaining a constant pressure inside the cooling chamber 3. Meanwhile, the liquid sprayed onto the radiator 51 flows through the drain trough 54 into the water tank 53, forming a circulation. During this process, the condenser 59 cools the liquid inside the water tank 53.
