Description

Technical Field

[0001] The present invention relates to the technical field of heat exchangers, in particular to a short-term cooling device for a thermal storage incinerator. Background Art

[0002] Regenerative incinerators for chemical environmental protection equipment operate at an optimal operating condition, where a certain concentration of organic waste gas maintains the equipment's self-combustion. When the waste gas concentration is low, additional natural gas combustion is required to increase the temperature and maintain a high temperature to decompose pollutants. When the waste gas concentration is high, fresh air is introduced to reduce the concentration.

[0003] There are many different types of business production. Some small businesses face limited capital and unstable orders at the start-up stage, leaving many production lines unfinished. Therefore, environmental protection equipment is initially designed with a lower capacity, minimizing both investment and operating costs. As a business grows and orders increase, the production line generates more exhaust gas. Depending on the production process, if the regenerative incinerator draws in fresh air to reduce exhaust gas concentration, the fresh air volume of the production line will decrease. However, increased exhaust gas concentration in the production line will affect product performance. This creates a dilemma: reducing production lines or causing high temperatures in the regenerative incinerator, which could compromise equipment safety. Even if a new, larger-capacity regenerative incinerator is built, production will be halted, investment will increase, and the existing site will need to be redeveloped, a burden the business faces. Even if a new, larger-capacity regenerative incinerator is built, it will require production halts and increased investment, requiring redevelopment of the existing site, a burden the business cannot afford. Even if the new facility is built, orders will fluctuate periodically, and production lines will undergo regular maintenance cycles. When production lines are underutilized and exhaust gas concentrations are low, the large-capacity regenerative incinerator will likely require natural gas combustion, increasing production costs. The existing regenerative incinerator, which utilizes waste heat, cannot be used in the production line until summer. This means that multiple factors, combined to cause the regenerative incinerator to overheat, are a rare occurrence. Activating the emergency discharge valve to reduce the temperature would damage the chimney's environmental monitoring equipment. Therefore, a new, cost-effective solution to these technical issues was urgently needed. Summary of the Invention

[0004] To address the aforementioned issues, the present invention discloses a short-term cooling device for a regenerative incinerator. The device comprises a cooling pool, within which a heat exchange mechanism is located. One end of the heat exchange mechanism is fixedly connected to a piping structure, and the other end of the heat exchange mechanism is fixedly connected to a fan pipeline. Specifically, water is stored in the cooling pool, and one end of the piping structure is fixed to indoor equipment. High-temperature gas from the indoor equipment enters the heat exchange mechanism, where it is cooled in the cooling pool.

[0005] The heat exchange mechanism includes a tapered outlet pipe and a tapered inlet pipe. These pipes are connected to a plurality of heat exchange tubes. The smaller end of the tapered outlet pipe is connected to the fan pipeline, while the smaller end of the tapered inlet pipe is connected to the pipeline structure. The heat exchange tubes exchange heat with the water in the cooling pool, achieving cooling.

[0006] Preferably, the heat exchange mechanism further comprises a second bracket, and the second bracket supports and fixes the heat exchange tube, and the side wall of the tapered outlet pipe is fixedly connected with a sewage pipe. The first bracket is used to support and fix the heat exchange tube, and the sewage pipe is used to drain away the stains inside the heat exchange mechanism.

[0007] Preferably, an expansion joint is provided between the tapered inlet pipe and the pipeline structure. Due to the phenomenon of thermal expansion and contraction, the dimensions of components such as pipes change, and the expansion joint balances this change to ensure the normal operation of the device.

[0008] Preferably, the cooling pool includes a pool body, an upper side wall of the pool body is fixedly connected to a water inlet pipe, and one end of the water inlet pipe is fixedly connected to a float valve. During the cooling process, since water inside the pool body evaporates continuously, the water inlet pipe is provided, and the float valve is provided to achieve automatic water replenishment.

[0009] Preferably, the pipeline structure includes a pipe, one end of the pipe is connected to the tapered inlet pipe, the lower part of the pipe is fixedly connected to the first bracket, and the other end of the pipe is fixedly connected to the indoor equipment.

[0010] Preferably, the side wall of the pipeline is covered with a thermal insulation layer, a high-temperature valve is provided on the pipeline, and a water baffle is also provided on the side wall of the pipeline, the water baffle is located above the cooling pool to prevent water vapor from wetting the thermal insulation layer.

[0011] The beneficial effects of the present invention are as follows:

[0012] 1. The modification of existing regenerative incinerator equipment is small, the production line needs to be shut down for a short time, and at the same time, it does not require a large amount of investment from the enterprise. It can solve the high temperature problem of the regenerative incinerator and improve the safety of equipment operation. It also has low manufacturing and installation costs, few moving parts, and low maintenance costs.

[0013] 2. The waste gas can be discharged without pollution after high-temperature treatment, and the temperature of the waste gas discharge can be reduced to avoid damage to the environmental monitoring equipment on the chimney. BRIEF DESCRIPTION OF THE DRAWINGS
