Description

Technical Field

[0001] The utility model relates to the technical field of thermal oxidation furnaces, in particular to a heat storage type thermal oxidation furnace with a full-automatic air reduction and concentration increase system. Background Art

[0002] The regenerative thermal oxidation furnace with a fully automatic air reduction and concentration increase system has high purification efficiency, low energy consumption and good reliability. It is widely used in the treatment of organic waste gas emitted from ovens in the printing, coating and other industries. The regenerative thermal oxidation furnace is also called a regenerative thermal incinerator. Its principle is to heat the organic waste gas to above 760 degrees Celsius, so that the VOC in the waste gas is decomposed into carbon dioxide and water during oxidation. The high-temperature gas produced by oxidation flows through a special ceramic heat storage body, causing the ceramic body to heat up and "store heat". This "heat storage" is used to preheat the subsequent organic waste gas, thereby saving fuel consumption for heating the waste gas.

[0003] The patent of Chinese Patent Publication No. CN214172259U discloses a heat storage thermal oxidation furnace, including a furnace body, the bottom end of the furnace body is connected to a supporting leg, the outer wall of the supporting leg is installed with a controller, a combustion chamber and a ceramic heat storage body are installed inside the furnace body, the ceramic heat storage body is located on one side of the combustion chamber, a burner is installed at the upper end of the furnace body, and the bottom end of the furnace body is symmetrically connected to an air supply branch pipe, and the bottom end of the air supply branch pipe is connected to an air supply main pipe. The utility model adds a filter box and a filter plate. Before the organic waste gas is treated, it is first passed into the filter box and filtered by the filter plate, which can effectively filter out solid impurities in the organic waste gas, which is beneficial to subsequent treatment and can avoid pipeline blockage. In addition, the filter plate is inserted and fixed through the cooperation of the fixing plate and the slot, which is beneficial to its subsequent rapid removal and replacement. Although the filter plate can filter out solid impurities in the organic waste gas, the filter plate needs to be frequently stopped for replacement, which is not conducive to improving the treatment efficiency of the thermal oxidation furnace.

DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] like Figure 1-3 As shown, a heat storage thermal oxidation furnace with a fully automatic air reduction and concentration increase system includes a thermal oxidation furnace 1, a lower air inlet of the thermal oxidation furnace 1 is provided with an air duct 2, one end of the air duct 2 away from the thermal oxidation furnace 1 is connected to the upper air outlet of a filter mechanism 3, and a connecting pipe 4 is provided on the side of the filter mechanism 3 away from the air duct 2.

[0021] In this embodiment, the filtering mechanism 3 includes a fan 303, a cleaning component 304, a filter 305 and a filter box 307. The fan 303 is installed at the lower part of the filter box 307 away from the thermal oxidation furnace 1. The air outlet of the fan 303 is fixedly connected to the air inlet on the side of the filter box 307 away from the thermal oxidation furnace 1. The air inlet of the fan 303 is connected to one end of the connecting pipe 4. The filter 305 is installed in the middle of the side of the filter box 307 close to the thermal oxidation furnace 1. The cleaning component 304 is installed in the upper and middle part of the side of the filter box 307 close to the thermal oxidation furnace 1. An inspection door 302 is installed on one side of the filter box 307. A glass observation window 301 is installed in the middle of the inspection door 302. A sedimentation baffle 306 is installed on the side of the filter box 307 close to the fan 303.

[0022] Specifically, the exhaust gas is introduced into the filter box 307 through the connecting pipe 4 by the fan 303, and then the large particles of dust and impurities in the exhaust gas are precipitated through the sedimentation baffle 306, and then the small particles of dust are filtered through the filter net 305, so that the dust and impurities are trapped in the filter mechanism 3, preventing the dust in the exhaust gas from clogging the ceramic heat storage bed, thereby ensuring the processing efficiency of the thermal oxidation furnace 1.

[0023] In this embodiment, the cleaning component 304 includes a driving component, a support frame 3043, a nozzle 3044, a branch pipe 3045 and a hose 3046. The driving component is installed in the upper and middle part of the filter box 307 close to the thermal oxidation furnace 1, the branch pipe 3045 is installed in the lower part of the driving component, the nozzle 3044 is installed in the lower part of the branch pipe 3045, one end of the hose 3046 is connected to the external air pump, and the other end of the hose 3046 is fixedly connected to one end of the branch pipe 3045. The driving component includes a motor 3041, a reciprocating screw rod 3042, a support frame 3043 and a limit rod 3047. The front and rear ends of the reciprocating screw rod 3042 are rotatably connected to one side of the filter box 307, and the front and rear ends of the limit rod 3047 are fixedly connected to the other side of the filter box 307.

[0024] Specifically, the external air pump transports high-pressure gas to the inside of the branch pipe 3045 through the hose 3046, and sprays it out through the nozzle 3044, thereby cleaning the dust attached to the lower side of the filter 305. At the same time, the motor 3041 drives the reciprocating screw 3042 to rotate. Since the limit rod 3047 limits the support frame 3043 to rotate with the support frame 3043, the reciprocating screw 3042 drives the support frame 3043 to move forward and backward, and then the nozzle 3044 cleans the dust on the filter 305 in all directions, thereby ensuring the filtering effect of the filter box 307 and the processing efficiency of the thermal oxidation furnace 1.

[0025] Working principle:

[0026] The exhaust gas is introduced into the filter box 307 through the connecting pipe 4 by the fan 303, and then the large particles of dust and impurities in the exhaust gas are precipitated through the sedimentation baffle 306, and then the small particles of dust are filtered through the filter 305, so that the dust and impurities are trapped in the filter mechanism 3, so as to prevent the dust in the exhaust gas from clogging the ceramic heat storage bed, thereby ensuring the processing efficiency of the thermal oxidation furnace 1, and the external air pump transports the high-pressure gas to the inside of the branch pipe 3045 through the hose 3046, and sprays it through the nozzle 3044, so as to clean the dust attached to the lower side of the filter 305, and at the same time, the motor 3041 drives the reciprocating screw 3042 to rotate. Since the limit rod 3047 limits the support frame 3043 to rotate with the support frame 3043, the reciprocating screw 3042 drives the support frame 3043 to move back and forth, and then the nozzle 3044 cleans the dust on the filter 305 in an all-round way, thereby ensuring the filtering effect of the filter box 307 and the processing efficiency of the thermal oxidation furnace 1.
