Description

Technical Field

[0001] This utility model relates to the field of waste incineration equipment technology, and in particular to a high-efficiency waste incinerator flue gas adsorption device. Background Technology

[0002] Many complex reactions occur during waste incineration, producing gaseous pollutants harmful to the environment and human health. These gaseous pollutants can be classified into several categories based on their properties, including acidic gases, heavy metals, particulate matter, and organic pollutants. While using the heat energy from waste incineration to generate electricity, waste incineration plants primarily utilize the adsorption properties of activated carbon to adsorb dioxins and volatile heavy metals from dust, preventing secondary pollution that could impact and damage human society and the ecological environment. Traditionally, flue gas adsorption is typically high-temperature adsorption, where the flue gas discharged from the boiler is cooled to approximately 200°C via a cooling tower before entering a flue gas adsorption tower for high-temperature adsorption purification. However, high-temperature flue gas adsorption suffers from high adsorbent consumption, poor adsorption efficiency, and high nitrogen oxide content in the purified flue gas, failing to achieve near-zero emissions, and urgently needs improvement. Utility Model Content

[0003] To address the shortcomings of the aforementioned technologies, this utility model provides a high-efficiency flue gas adsorption device for waste incinerators, comprising an inlet pipe, a connecting pipe, a cooling box, an adsorption pipe, and an exhaust pipe connected to the exhaust port of the waste incinerator. The inlet pipe is connected to the cooling box, and both ends of the connecting pipe are respectively connected to the cooling box and the adsorption pipe. The exhaust pipe is connected to the adsorption pipe. The cooling box contains a flue gas cooling device, which includes a multi-stage U-shaped pipe, cooling water, a circulation pipe, and a water pump. Both ends of the multi-stage U-shaped pipe are respectively connected to the inlet pipe and the connecting pipe, and both ends of the circulation pipe are connected to the bottom and top of the cooling box, respectively. The water pump is connected to the circulation pipe, and the top of the cooling box has a ventilation opening.

[0004] Using the above technical solution, the flue gas discharged from the exhaust port of the waste incinerator first enters the cooling box, then flows along the multi-stage U-shaped pipe, and then enters the adsorption pipe through the connecting pipe. When passing through the multi-stage U-shaped pipe, the flue gas in the pipe is cooled by the cooling water in the cooling box. The cooling water is circulated through the circulation pipe and water pump, which can effectively cool the flue gas. After cooling, the adsorption can be carried out, which can improve the adsorption and purification effect.

[0005] Further features of this invention: A water supply tank is provided on one side of the dust removal box. The water supply tank is provided with a water supply pipe and a connecting water pipe connected to a water source. The connecting water pipe is connected to the cooling box via a water pump. A drain pipe is provided on the cooling water tank. Solenoid valves are provided on both the water supply pipe and the drain pipe. A temperature sensor for water temperature monitoring is provided inside the cooling box.

[0006] Using the above technical solution, a water supply tank is provided on one side of the dust removal box. The water supply tank is equipped with a water supply pipe and a connecting water pipe connected to a water source. The connecting water pipe is connected to the cooling box via a water pump. A drain pipe is provided on the cooling water tank. Both the water supply pipe and the drain pipe are equipped with solenoid valves. A temperature sensor for water temperature monitoring is provided inside the cooling box. When the cooling water in the cooling box has undergone multiple circulations, and the temperature sensor detects that the water temperature is too high, the solenoid valve on the drain pipe opens to discharge the water with the increased temperature. After discharge, the solenoid valve closes, and the solenoid valve on the water supply pipe and the water pump on the connecting water pipe start simultaneously to replenish the cooling box with low-temperature water.

[0007] A further feature of this invention is that the multi-stage U-tube includes several arc-shaped tubes and several sealing connectors, and the arc-shaped tubes are detachably connected to each other through the sealing connectors.

[0008] By adopting the above technical solution, since the multi-stage U-tube includes several arc-shaped tubes and several sealing connectors, and the arc-shaped tubes are detachably connected to each other through sealing connectors, the multi-stage U-tube can be disassembled periodically to clean the inside of the tube and avoid blockage.

[0009] A further feature of this invention is that the adsorption tube includes a pair of connecting tube heads, a pair of adapters, and several thin tubes. Both ends of the several thin tubes are connected to the connecting tube heads via adapters, and each of the several thin tubes is provided with a filling chamber for filling activated carbon.

After the water is discharged, the solenoid valve closes. The solenoid valve on the water supply pipe and the water pump on the connecting water pipe start simultaneously to replenish the cooling box with low-temperature water.

Both ends of the several thin tubes are connected to the connecting tube heads through adapters, and each of the several thin tubes is provided with a filling chamber 23 for filling activated carbon.
