Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment of catalytic combustion equipment, and specifically relates to a waste gas treatment device for a catalytic combustion equipment. Background Technique

[0002] A catalytic combustion equipment refers to a device or equipment that burns under the action of a catalyst. The working principle of the catalytic combustion equipment is that with the help of a catalyst, the organic waste gas undergoes flameless combustion at a relatively low ignition temperature, and the organic waste gas is decomposed into carbon dioxide and water vapor. However, the catalytic combustion waste gas cannot filter and purify harmful substances in the waste gas. If such harmful substances are directly discharged into the atmosphere, it has a certain degree of pollution. Therefore, we propose a waste gas treatment device for a catalytic combustion equipment. Content of the Utility Model

[0003] The purpose of the utility model is to provide a waste gas treatment device for a catalytic combustion equipment, which can prevent dust in the waste gas from entering the internal part of the RTO combustion furnace, and solves the problems raised in the above background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A waste gas treatment device for a catalytic combustion equipment, including a catalytic combustion equipment main body, a filtration box, a purification box and a base. The catalytic combustion equipment main body, the filtration box and the purification box are arranged in sequence and fixedly installed on the base. A first air duct is fixedly connected between the catalytic combustion equipment main body and the filtration box. A second air duct is fixedly connected to the side of the filtration box opposite to the first air duct. The other end of the second air duct is fixedly connected to the purification box. A purification agent is arranged in the purification box;

[0005] On one side of the filtration box that is not connected to the first air duct and the second air duct, a first cleaning box is fixedly installed, and on the other side corresponding to the first cleaning box, a second cleaning box is fixedly installed. The filtration box is respectively provided with through holes at the joints with the first cleaning box and the second cleaning box. The first cleaning box, the filtration box and the second cleaning box are communicated through the through holes. At the position corresponding to the through hole at the bottom of the first cleaning box, a slide rail is fixedly installed. The slide rail passes through the filtration box through the through hole and extends to the bottom of the second cleaning box. A first filter plate is arranged in the filtration box. The first filter plate faces the first air duct. On the side of the first filter plate facing the second cleaning box, a second filter plate with the same structure is arranged. The first filter plate and the second filter plate are fixedly connected by a connecting column. The bottoms of the first filter plate and the second filter plate are both slidably connected to the slide rail. On the side of the first filter plate away from the second filter plate, a push rod is fixedly installed. The other end of the push rod passes through the side wall of the first cleaning box and extends outwards and is fixedly installed with a cylinder. The cylinder is fixedly connected to the side wall of the first cleaning box;

[0006] A motor is fixedly installed at the top of the purification tank. Above the motor is provided a medicine storage tank. The bottom of the medicine storage tank is fixedly connected to the periphery of the top of the purification tank. A liquid infusion pipe is fixedly installed at the bottom of the medicine storage tank. The lower end of the liquid infusion pipe passes through the top of the purification tank and extends into its interior. The output end of the motor faces downward and is fixedly installed with a rotating shaft. The rotating shaft passes through the top of the purification tank and extends to the lower part inside it. A number of stirring blades are fixedly connected around one side of the rotating shaft near the lower end. On the side of the bottom of the purification tank away from the second air duct, a liquid discharge pipe is fixedly connected. Above the side of the purification tank where the liquid discharge pipe is installed, an exhaust pipe is connected. At the position corresponding to the exhaust pipe inside the purification tank, a gas collection tank is fixedly installed. On the side of the gas collection tank away from the exhaust pipe, a mounting frame is fixedly installed. An exhaust fan is installed inside the mounting frame.

[0007] The waste gas after catalytic combustion enters the filtration tank from the first air duct and is filtered through the first filter plate to filter out the dust in the waste gas. Then it enters the purification tank from the second air duct. The medicine in the purification tank is stirred by the stirring blades, so that the waste gas and the medicine are fully mixed, and the harmful substances in the waste gas are absorbed and decomposed. Finally, the purified gas rises to the top of the purification tank, and then is sent into the gas collection tank by the exhaust fan and finally discharged from the exhaust pipe. When the dust blocks the first filter plate, the first filter plate is pulled into the first cleaning box by the cylinder for the staff to clean. At the same time, the second filter plate moves into the filtration tank to replace the first filter plate for filtration, effectively avoiding the problem that the harmful substances in the waste gas are directly discharged into the atmosphere, thus causing environmental pollution.

[0008] Preferably, sealing plates matching the first filter plate are fixedly installed on both sides of the first filter plate in the filtration tank facing the first air duct and the second air duct. By setting the sealing plates, the sealing performance is increased, preventing the waste gas from directly passing through the gap between the filter plate and the filtration tank and entering the purification tank, thus causing the problem that the medicine in the purification tank is polluted by dust and the purification effect is reduced.

[0009] Preferably, inspection openings are provided on one side of the first cleaning box and the second cleaning box facing the main body of the catalytic combustion equipment, and inspection door panels are installed on the inspection openings. It is convenient for the staff to open the inspection door panel and perform inspection and cleaning on the filter plate from the inspection opening.

[0010] Preferably, valves are installed on both the liquid infusion pipe and the liquid discharge pipe. The opening and closing of the liquid infusion pipe and the liquid discharge pipe are controlled by the valves.

[0011] Preferably, a feeding port is provided at the top of the medicine storage tank. The feeding port is used to put the medicine into the medicine storage tank for standby. When the purification effect of the medicine in the purification tank is reduced, the valve of the liquid discharge pipe is opened to discharge the medicine. After discharging, the valve of the liquid discharge pipe is closed, and then the valve of the liquid infusion pipe is opened to transport the standby medicine in the medicine storage tank into the purification tank.

[0012] Compared with the prior art, the utility model adopts the above technical solutions and has the following technical effects:

[0013] The utility model filters the dust in the waste gas through a filter box to avoid dust pollution of the medicament and reduce the purification effect of the medicament. Two filter plates and a cleaning box are provided, so that when one filter plate is blocked by dust, the other filter plate can directly replace it, improving the work efficiency; by providing a purification box and stirring blades, a medicament for purifying harmful substances in the waste gas is provided in the purification box. After the waste gas enters the purification box, the medicament is stirred by the stirring blades, so that the medicament and the waste gas are fully mixed, thereby decomposing and absorbing the harmful substances in the waste gas and avoiding environmental pollution caused by the direct discharge of the harmful substances in the waste gas into the atmosphere.
