Description

Technical Field

[0001] The utility model belongs to the technical field of waste gas treatment, and particularly relates to an RTO multi-chamber regenerative thermal oxidation combustion treatment device. Background Art

[0002] RTO is a device for purifying organic waste gas (VOCs) through thermal incineration method, called a regenerative thermal oxidizer. When the VOC in the waste gas reaches a certain concentration (usually ≥ 2000mg / m 3 、According to the different calorific values and concentrations of the waste gas), without supplementary heat, only relying on the VOCs themselves can achieve thermal incineration, keeping the temperature in the RTO at 800 - 850 °C. However, in actual production, the concentration of the waste gas often changes. When the concentration of VOCs in the waste gas becomes smaller and cannot reach self-equilibrium, the RTO cannot maintain a temperature above 800 °C by the waste gas itself, and then the burner configured on the RTO needs to be ignited to maintain the cracking temperature of the waste gas. In the process of treating waste gas by the existing RTO combustion treatment equipment, most are set as single combustion chambers. During the treatment process, the combustion temperature is relatively high, and the service life of the equipment is relatively short. Therefore, an RTO multi-chamber regenerative thermal oxidation combustion treatment device is needed to solve the above problems. Summary of the Utility Model

[0003] The purpose of the utility model is to provide an RTO multi-chamber regenerative thermal oxidation combustion treatment device.

Specific implementation manners

[0021] In order to enable those skilled in the art to better understand the present utility model, the technical solutions of the present utility model will be further described below in conjunction with the drawings and embodiments.

[0022] As Figures 1-6 shown, an RTO multi-chamber regenerative thermal oxidation combustion treatment device of the present utility model includes a base 1, several regenerative chambers 10 and a combustion chamber 11. The several regenerative chambers 10 are linearly arranged on the upper side of the base 1, the combustion chamber 11 is fixedly installed on the upper side of the several regenerative chambers 10, the combustion chamber 11 is in communication with the several regenerative chambers 10, several square tubes 12 matching the regenerative chambers 10 are installed on the upper side of the base 1, ventilation tubes 13 communicating with each other are fixedly provided on the front and rear sides of the middle square tube 12 and the square tubes 12 on both sides, an air inlet tube 14 is fixedly provided on the side wall of the square tube 12 on the right side, two baffle plates 15 symmetrically distributed front and rear are fixedly provided on the lower sides of the several regenerative chambers 10, the several baffle plates 15 are all matched with the square tubes 12, ventilation holes 16 are opened in the several baffle plates 15, cover plates 17 matching the ventilation holes 16 are installed on the front and rear sides inside the several square tubes 12, and control components matching the cover plates 17 are provided on the front and rear sides inside the several square tubes 12;

[0023] A control main board is installed in the present utility model, and the control main board is electrically connected to the control components, so that the six cover plates 17 operate independently, the cover plates 17 on the front and rear sides are alternately closed and opened, ensuring that the incoming waste gas can flow through the regenerative chamber 10 and the combustion chamber 11, and at the same time enabling the six cover plates 17 to be used alternately, extending the service life of the cover plates 17;

[0024] When the utility model is in use, the exhaust gas first enters the square tube 12 on the right side from the air inlet 14, and under the control of the control component, the two staggered cover plates 17 are opened, and the exhaust gas enters from the ventilation hole 16 on the front side, and then goes up to the heat storage chamber 10 for preheating. After the preheating is completed, it goes up to the combustion chamber 11 for combustion treatment. The treated gas flows to the heat storage chamber 10 corresponding to the rear cover plate 17, and then flows downward from the cover plate 17 opened on the rear side to the square tube 12 on the rear side, and then flows to the left from the square tube 12 on the rear side to be discharged. Under the control of the cover plate 17 of the control component, several heat storage chambers 10 are used alternately. When the exhaust gas after the combustion treatment in the combustion chamber 11 passes through the heat storage chamber 10, there will be residual heat. When the newly entered exhaust gas passes through the heat storage chamber 10, the exhaust gas is preheated to facilitate the exhaust gas to reach the required combustion temperature;

[0025] Furthermore, the utility model is equipped with cooling pipes, which are respectively connected to a plurality of square tubes 12, and the used square tubes 12 are cooled by blowing air through the cooling pipes, thereby reducing the temperature of the cover plate 17 and the side wall of the square tube, and extending the service life of the cover plate 17;

[0026] Furthermore, during the use of the utility model, when the exhaust gas is burned, oil impurities will remain at the bottom of the heat storage chamber 10. During the air blowing cooling process of the cooling pipe, the oil impurities fall off due to the cold and hot stimulation, and are discharged from the device, ensuring that the exhaust gas enters the heat storage chamber 10 normally.

[0027] The utility model blows exhaust gas into the interior of the device through an air inlet tube, and under the control of a separate control component, the cover plates on the front and rear sides slide independently, so that the ventilation holes for air intake and exhaust in the combustion chamber are continuously replaced, so that six cover plates are used alternately, and at the same time, a plurality of heat storage chambers are used alternately, thereby extending the service life of the cover plates and the heat storage chambers.

[0028] The control assembly includes a support plate 20 fixedly provided on the side wall of the square tube 12, a driving rod 21 is rotatably mounted on the upper side of the support plate 20, the driving rod 21 is fixedly connected to the cover plate 17 concentrically, a motor 22 is installed on the upper side of the support plate 20, the output shaft of the motor 22 is transmission-connected to the driving rod 21, two electric telescopic rods 23 symmetrically distributed on the upper side of the support plate 20 are installed, a mounting seat 24 is fixedly provided on the side wall of the motor 22, and the output ends of the two electric telescopic rods 23 are fixedly connected to the mounting seat 24;

[0029] During the use of the present utility model, when it is necessary to move the cover plate 17, the output end of the electric telescopic rod 23 drives the mounting seat 24 to move. The mounting seat 24 drives the motor 22 to move. The motor 22 drives the driving rod 21 to move. The driving rod 21 drives the cover plate 17 to move. The motor 22 synchronously drives the driving rod 21 to rotate. The driving rod 21 synchronously drives the cover plate 17 to rotate. Thus, the cover plate 17 rotates and closes at the same time, making the cover plate 17 tightly abut against the ventilation holes 16, preventing waste gas from flowing into through the ventilation holes 16 closed by the cover plate 17, and ensuring the normal use of the device.

[0030] On the side of the baffle 15 away from the motor 22, a connecting seat 30 matching the driving rod 21 is fixedly provided. On the side of the connecting seat 30 away from the motor 22, a number of first rollers 31 matching the driving rod 21 are installed. On the inner side wall of the square tube 12, a fixing seat 32 matching the driving rod 21 is provided. On the side of the fixing seat 32 away from the motor 22, a number of second rollers 33 matching the driving rod 21 are installed.

[0031] When the present utility model is in use, when the motor 22 and the electric telescopic rod 23 synchronously drive the cover plate 17 to move through the driving rod 21, the driving rod 21 abuts against the first rollers 31 and the second rollers 33 while rotating and moving, reducing the friction between the driving rod 21 and the fixing seat 32 and the connecting seat 30, facilitating the rotation and movement of the driving rod 21 at the same time, and ensuring the smooth use of the device.

[0032] A blower 34 is installed on the upper side of the base 1. An air inlet pipe 35 is installed between the blower 34 and the air inlet tube 14; increasing the intake of waste gas into the air inlet tube 14 and improving the waste gas treatment efficiency of the device.

[0033] A filter 36 is installed on the upper side of the base 1. A connecting pipe 37 is installed between the filter 36 and the blower 34; filtering the waste gas entering the device, preventing larger impurities, etc. from entering the interior of the device, and ensuring the normal use of the device.

[0034] A heat exchange chamber 38 communicating with the left square tube 12 is installed on the upper side of the base 1. A chimney 39 is installed on the upper side of the base 1. An exhaust pipe 40 is installed between the chimney 39 and the heat exchange chamber 38; during the use of the present utility model, when the processed exhaust gas passes through the heat exchange chamber 38, heat exchange occurs. The heat exchange chamber 38 cools the processed exhaust gas, preventing the temperature of the chimney 39 from being too high during the discharge process and extending the service life of the chimney 39. At the same time, the hot air in the heat exchange chamber 38 flows back into the heat storage chamber 10 to preheat the incoming waste gas, making full use of the heat during the waste gas treatment process.

[0035] Further, a number of evacuation valves are installed in the device. When the temperature of the combustion chamber 11 is too high, the high-temperature flue gas is discharged to ensure the normal use of the combustion chamber 11. At the same time, the discharged high-temperature flue gas exchanges heat through the heat exchange chamber 38.

Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present invention should still be covered by the claims of the present invention.
