Description

Technical Field

[0001] This utility model belongs to the technical field of municipal solid waste pyrolysis furnaces, and in particular relates to a pyrolysis gas guiding device for municipal solid waste pyrolysis furnaces. Background Technology

[0002] Existing waste treatment technologies mainly involve incinerating waste by adding coal or diesel oil. However, due to the complex composition of waste, the direct emission of exhaust gases from combustion can cause significant air pollution.

[0004] The device only fixes the conveying pipe to prevent leakage during the gas introduction process. However, after the gas enters the waste pyrolysis furnace, the gas itself is at a high temperature and needs to be cooled down. The cooled gas also needs to be purified before it can be used in the next step. Therefore, a pyrolysis gas introduction device for municipal solid waste pyrolysis furnace is proposed. Utility Model Content

[0012] Furthermore, the induced draft fan has explosion-proof and corrosion-resistant properties.

[0013] The beneficial effects of this utility model are:

[0014] 1. This utility model involves high-temperature gas entering the cooling tank through a gas guide pipe, and a pump drawing cooling water, which then enters an atomizing sprayer through a first and second conveying pipe. The atomizing sprayer then sprays the cooling water onto the high-temperature gas, thereby cooling the gas. This prevents the tar molecules in the gas from forming large molecular chains, causing them to condense into tiny droplets, which are easier to remove later. At the same time, it can also remove some acidic gases and dust.

[0015] 2. This utility model uses an air extraction machine to extract the cooled gas, which then enters the purification integrated device through the first and second gas delivery pipes. The purification integrated device captures tar droplets and fine dust in the gas and sprays and washes the gas to further remove residual tar, water-soluble acidic gases and dust. Finally, the gas is further cooled to condense water and heavy tar and perform oil-water separation. After purification, the gas temperature is reduced, the volume is reduced, and the gas is relatively clean. After being pressurized, the gas is stably transported to the user unit through pipelines.

Detailed Implementation

[0024] like Figures 1 to 6 The present invention discloses a gas guiding device for pyrolysis gas in a municipal solid waste pyrolysis furnace, comprising a base plate 1, a controller 2 mounted on the base plate 1, a support frame 3 fixedly connected to the base plate 1, a cooling tank 4 fixedly connected to the support frame 3, a gas guiding pipe 5 fixedly connected to the cooling tank 4, a gas valve 6 mounted on the gas guiding pipe 5, a waste liquid storage tank 7 fixedly connected to the base plate 1, a discharge pipe fixedly connected to the waste liquid storage tank 7, a first electric valve 8 mounted on the discharge pipe of the waste liquid storage tank 7, a discharge pipe 9 connecting the cooling tank 4 and the waste liquid storage tank 7, a second electric valve 10 mounted on the discharge pipe 9, a cooling mechanism 11 between the base plate 1 and the cooling tank 4, and a purification mechanism 12 between the base plate 1 and the cooling tank 4.

[0025] The controller 2 is equipped with indicator lights and a buzzer.

[0026] The cooling mechanism 11 includes a liquid storage tank 111, a first fixed frame 112, a pump 113, a first delivery pipe 114, a second delivery pipe 115, an atomizing sprayer 116, a first liquid level sensor 117, and a second liquid level sensor 118. The liquid storage tank 111 is fixedly connected to the base plate 1, and the first fixed frame 112 is fixedly connected to the support frame 3. The pump 113 is fixedly installed on the first fixed frame 112. The first delivery pipe 114 connects the pump 113 to the liquid storage tank 111. The pump 113 is connected to the cooling tank 4. A second delivery pipe 115 is connected between the two. An atomizing sprayer 116 is installed inside the cooling tank 4. The atomizing sprayer 116 is connected to the second delivery pipe 115. The cooling water sprayed by the atomizing sprayer 116 is used to cool the gas. A first liquid level sensor 117 is installed inside the liquid storage tank 111. The first liquid level sensor 117 is used to detect the liquid level of the cooling water in the liquid storage tank 111. A second liquid level sensor 118 is installed inside the liquid storage tank 111. The second liquid level sensor 118 is used to detect the liquid level of the cooling water in the liquid storage tank 111.

[0027] The purification mechanism 12 includes a second fixed frame 121, an air extractor 122, a first air delivery pipe 123, a second air delivery pipe 124, and a purification integrated device 125. The second fixed frame 121 is fixedly connected to the support frame 3. The air extractor 122 is fixedly installed on the second fixed frame 121. The air extractor 122 is used to extract the cooled gas. The first air delivery pipe 123 is connected between the air extractor 122 and the cooling tank 4. The purification integrated device 125 is installed on the base plate 1. The purification integrated device 125 is used to purify the cooled gas. The second air delivery pipe 124 is connected between the purification integrated device 125 and the air extractor 122.

[0028] The purification integrated device 125 is composed of an electrostatic tar collector, a scrubbing tower, a condenser separator, a separation tank, a pressure stabilizing tank, and an induced draft fan.

[0029] The air duct 5 is made of 310S stainless steel.

[0030] The induced draft fan has explosion-proof and corrosion-resistant properties.

[0031] The working principle of this invention is as follows: After cooling water is injected into the storage tank, when the cooling water level reaches the preset threshold of the second level sensor, the indicator light illuminates, and the injection of cooling water stops. Then, the second electric valve is controlled to open the discharge pipe, and subsequently, the gas valve is controlled to open the gas guide pipe channel. High-temperature gas enters the cooling tank through the gas guide pipe. The pump draws the cooling water, which then enters the atomizing sprayer through the first and second conveying pipes. The atomizing sprayer then sprays the cooling water onto the high-temperature gas, thereby cooling the gas and preventing the tar molecules in the gas from forming large molecular chains, instead causing them to condense into tiny droplets. This facilitates subsequent removal and removes some acidic gases and dust. The waste liquid enters the waste liquid storage tank through the discharge pipe. The exhaust pump extracts the cooled gas, which then enters the purification integrated device through the first and second gas delivery pipes. The purification integrated device captures tar droplets and fine dust in the gas and sprays and washes the gas to further remove residual tar, water-soluble acidic gases, and dust. Finally, the gas is further cooled to condense water and heavy tar and separate oil and water. After purification, the gas temperature is lower, the volume is smaller, and it is relatively clean. After being pressurized, the gas is stably transported to the use unit through pipelines.

[0032] When the cooling water level is lower than the preset threshold of the first level sensor, the buzzer will sound to remind the user that cooling water needs to be added. When waste liquid needs to be drained, the first electric valve will open the waste liquid storage tank discharge pipe.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
