Description

Technical Field

[0001] The invention belongs to the field of waste gas treatment equipment, and specifically relates to a thermal storage incineration device and a switching method for a valve of the thermal storage incineration device. Background Art

[0002] In the organic waste gas treatment technology, incineration is widely regarded as a direct and effective treatment technology, among which regenerative thermal incineration (RTO) and regenerative catalytic combustion (RCO) technologies are favored due to their high treatment efficiency and heat recovery efficiency. At present, the main structural forms of regenerative thermal incinerators include fixed beds and rotating beds. The key component that affects the treatment efficiency of these two structures is the switching valve (rotary valve), which is responsible for the switching of air intake, air outlet and purge.

[0003] Since the sealing requirements of rotary valves are extremely strict, a gap on the sealing surface that is too large will cause air cross-flow and reduce the processing efficiency of the equipment; while a gap that is too small may cause the rotary valve to get stuck due to temperature fluctuations. In projects that handle large air volumes, the diameter of the rotary valve can reach 3-4 meters. Although the use of different sealing materials may improve the sealing, the processing efficiency is often sacrificed to ensure the smooth operation of the equipment. In addition, the machining cost of the rotary valve is relatively high, and its rotor sealing surface requires high-precision overall processing and assembly, which is difficult to meet on-site. It usually needs to be pre-assembled in the processing workshop, and transportation restrictions limit the processing capacity.

[0004] With the need to replace the sealing material of the rotary valve after long-term operation, the disassembly process is complicated. In addition, the structures and sealing materials of rotary valves produced by different manufacturers are different, resulting in poor versatility of equipment parts, and it is difficult to achieve factory control parameters after on-site reassembly. In order to reduce the leakage rate of the rotary valve, some inventions try to form an air curtain seal through high-pressure wind, but this may lead to waste of instrument air and excessive oxygen content at the exhaust port.

[0005] Since the treatment efficiency of traditional rotary RTO is difficult to guarantee, fixed bed RTO has become an option in projects with strict waste gas emission indicators such as petrochemical in recent years. However, fixed bed RTO occupies a large area. For example, a device that processes 50,000 Nm3 / h requires more than 60m² of space, while a rotary regenerative thermal incinerator can achieve the same treatment capacity within 30m². Therefore, in projects with limited space, users are more inclined to choose rotary incineration equipment.

[0006] There is currently no solution on the market that provides a rotary RTO or a circular RTO in the form of a poppet valve. Summary of the invention

[0007] The purpose of the present invention is to solve the problem that during the air intake, air outlet and purge process of the traditional rotary valve, the sealing surface gap is too large or too small, which will affect the processing efficiency of the equipment, and to provide a thermal storage incineration device and a switching method of the thermal storage incineration device valve. The present invention reduces leakage by lifting the valve assembly, thereby improving the overall air tightness and ensuring that the gas is not easy to cross-flow during the switching process; at the same time, the lifting valve can optimize the gas flow path and reduce unnecessary gas loss, thereby improving the processing efficiency and the lifting valve can be better integrated into the rotary RTO or circular RTO, further reducing the floor space and improving the space utilization of the equipment.

[0056] The valve group box design of the present invention has advantages in transportation and installation. It is divided into two parts (valve group box one and valve group box two) and transported to the site, and connected by riveting and welding. T-welds are used for welding, staggered by 150mm to enhance the connection strength. Long welds can be welded in sections and staggered. The weld length exceeds 500mm, and the sections are 500-800mm to reduce welding deformation. Since the connection surface does not involve the dynamic joint surface, the welding deformation will not affect the leakage rate of the valve body, and only a simple leakage test is required on site. At the same time, the valve group box can be subjected to mechanical leakage tests in the processing plant or a third-party organization, and the rotary valve supporting the rotary RTO cannot be subjected to such tests due to its special structure.

[0057] In terms of processing, the valve group box adopts traditional mechanical processing methods such as laser cutting, plate rolling and welding, which reduces the processing cost and is simpler than the turning process required for the existing rotary valve structure. At the same time, the design reduces the number of wearing parts, and the replacement process is relatively simple. Soft sealing materials (such as silicone rubber or fluororubber) are used, and ordinary workers can complete the replacement through the purge channel without the need for professionals.

[0058] The valve group box is provided with four air inlets, an air outlet and two purge ports, which improves the fault handling capability. During the operation of the equipment, if a valve fails, other valves can still share the load, and the system can continue to operate, reducing environmental accidents caused by shutdown due to failure. In addition, the internal channel of the valve group box does not contact the outside, eliminating the need for insulation materials, and the annular surface can realize heat exchange between the purge air and the intake air, saving energy. At the same time, it solves the problem of large floor space of fixed bed RTO / RCO and improves the space utilization of the equipment. In summary, the present invention exhibits significant advantages in many aspects, improves the reliability and economy of the equipment, and makes positive contributions to environmental protection and energy conservation.

[0059] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
