Description
Technical Field
The utility model belongs to the technical field of organic waste gas treatment, and particularly relates to an energy-saving heat storage incineration device.
Background
VOCs is PM2.5And O3The main precursor of the formation of the secondary pollutants, so the emission reduction technology of the VOCs is very important. The printing and packaging industry which belongs to the can making industry is one of the major industries for reducing emission of VOCs (volatile organic compounds), waste gas containing volatile organic compounds is generated in the production processes of bottom printing, color printing, internal coating and the like, and VOCs control measures are required before the waste gas is discharged to the atmosphere so as to meet the requirements of related environmental protection standards and reduce the pollution to the surrounding environment.
The Regenerative Thermal Oxidation (RTO) technology has strong adaptability, high efficiency and no secondary pollution, and gradually becomes the mainstream VOCs treatment technology in the tank making industry. The basic principle is as follows: the organic waste gas is heated to over 760 ℃ by the heat accumulator by utilizing the exchange function of heat storage and release of the heat accumulator system, so that VOCs in the waste gas are oxidized into CO2And H2O, and the high-temperature purified tail gas generated by oxidation flows through anotherA heat accumulator, which heats up the heat accumulator to store heat; after one period (or cycle) is finished, the flow direction of the organic waste gas and the purified tail gas can be changed by switching the valve, the periodic heat absorption/heat release function of the heat accumulator is realized, and the heat recovered from the high-temperature tail gas in the previous period is used for heating the newly-entered organic waste gas, so that the fuel consumption of waste gas temperature rise is saved.
Although the Regenerative Thermal Oxidizer (RTO) has the remarkable advantages of strong adaptability, high efficiency and no secondary pollution to the treatment of organic waste gas in the tank making industry, the following problems still exist in the actual engineering operation:
1) because the heat storage oxidation technology utilizes the heat storage body as a heat exchange medium, in order to save the consumption of natural gas, the recovery efficiency of the heat storage body is usually designed according to 95 percent, so that the consumption of the heat storage body is larger, the system resistance is usually over 3000Pa, and the running power consumption is high. And the organic waste gas contains silicon-containing compounds, silicon dioxide is generated during combustion in the combustion chamber, and after long-term operation, silicon dioxide powder is accumulated in the heat accumulator, so that the system operation resistance is further increased, and the power consumption is further increased.
2) Although the heat recovery efficiency of the heat storage body reaches 95 percent, the content of VOCs in the organic waste gas in the tank making industry is lower, sometimes even lower than 100mg/Nm3The available heat value of the waste gas is low, so that the normal safe and continuous operation of the RTO is maintained, the temperature of a combustion chamber is generally not lower than 760 ℃ according to the standard, the temperature difference of gases at an inlet and an outlet of the RTO is close to 40 ℃, a large amount of natural gas is required to be continuously consumed, and the operation cost is high.
3) Because the RTO needs to switch the valve every few minutes in order to realize the heat accumulation and heat release alternate replacement of the heat accumulator in the operation process, the air pressure at an RTO inlet is greatly fluctuated in the switching process, the normal operation of an upstream can manufacturing production line is influenced, and the phenomenon of toppling of the pop can is caused.

The technical problem to be solved by the utility model is to provide an energy-saving heat storage incineration device, aiming at the defects of the prior art, through arranging a bypass capable of timely adjusting air quantity to operate in cooperation with a heat storage oxidation incinerator (RTO), the total emission requirement is met, meanwhile, the consumption of electric energy and natural gas is reduced, and pressure fluctuation caused by valve switching is relieved.
The technical scheme adopted by the utility model for solving the technical problems is as follows:
an energy-saving heat accumulation incineration device comprises an inlet waste gas main pipe, a heat accumulation oxidation incinerator variable frequency fan, an outlet main pipe and a chimney which are sequentially connected; still including set up in the thermal oxidation burns burning furnace entry and thermal oxidation burns burning furnace frequency conversion fan export between the regulation bypass, be equipped with on the regulation bypass and adjust bypass frequency conversion fan.
In the above scheme, the device further comprises a controller, wherein the variable frequency fan of the thermal storage oxidation incinerator and the variable frequency fan of the regulating bypass are respectively connected with the controller, and the operating frequency of the two variable frequency fans is controlled by the controller.
In the scheme, the inlet waste gas main pipe is provided with a flowmeter and an inlet concentration measuring instrument, the flowmeter and the inlet concentration measuring instrument are respectively connected with the controller, the flow of the inlet waste gas main pipe measured by the flowmeter and the concentration measured by the inlet concentration measuring instrument are used as feedforward signals for adjusting the variable frequency fans of the regenerative oxidation incinerator and the bypass variable frequency fan, and the controller calculates and preliminarily determines the frequencies of the two variable frequency fans according to the feedforward signals.
In the above scheme, be equipped with the manometer on the female pipe of entry waste gas, the manometer with the controller is connected, and the pressure that the manometer measured is as regenerative oxidation and burns burning furnace variable frequency fan and bypass variable frequency fan's feedback control signal.
In the scheme, the outlet concentration measuring instrument is arranged on the outlet main pipe and is connected with the controller, and the outlet main pipe concentration measured by the outlet concentration measuring instrument is used as a feedback adjusting signal of the variable frequency fan and the bypass variable frequency fan of the regenerative oxidation incinerator.
The utility model has the beneficial effects that:
1. according to the utility model, the bypass capable of timely adjusting the gas amount is arranged to be matched with the RTO device for operation, so that when the total emission requirement is met, part of gas does not need to pass through the heat storage incinerator system, but directly passes through the bypass. The bypass resistance is far lower than that of the regenerative incinerator system, and natural gas is not required to be consumed, so that the power consumption and the natural gas consumption of the whole system are reduced, and the energy-saving effect is achieved.
2. Because part of gas can not pass through the heat storage incinerator system, when the RTO valve is switched, the gas generating pressure fluctuation is mixed with the bypass gas, so that the amplitude of the pressure fluctuation is reduced, and the tank-reversing phenomenon of an upstream tank-making production line is relieved.
