Description

TECHNICAL FIELD

[0001] The utility model relates to a sludge blending combustion technical field, concretely is a device that sludge blending combustion of boiler can remove peculiar smell. BACKGROUND

[0002] In the sludge blending combustion process of boiler, due to the complex composition of sludge, containing a large amount of organic matter, microorganism and other impurities, a variety of odor gases such as hydrogen sulfide, ammonia, volatile organic compounds (VOCs) are generated in the combustion process. These odor gases not only seriously affect the air quality of the surrounding environment, cause adverse effects on the life and health of residents, but also may lead to the risk of environmental regulation violation of related enterprises.

[0003] The existing various sludge blending combustion odor removal devices use the way of activated carbon adsorbing odor gas due to its high efficiency and relatively simple operation process, however, the existing such devices generally have a defect, that is, the contact time of gas with activated carbon is too short during the odor removal process, which makes the odor gas pass through the adsorption device quickly and cannot fully contact the surface of activated carbon, resulting in that most odor molecules are directly discharged from the device without being adsorbed, reducing the adsorption efficiency of activated carbon and the odor removal effect. SUMMARY

[0004] The utility model aims at providing a device for sludge blending combustion of boiler to solve the problems raised in the above background technology.

[0005] To solve the above technical problems, the utility model provides a device for sludge blending combustion of boiler, which comprises a gas collection box, a plurality of activated carbon blocks, a L-shaped guide plate and a small guide plate.

[0006] Further, the inside of the activated carbon block is provided with an electric heating wire.

[0007] Further, the inclination angle of the small guide plate is 15°.

[0008] Further, one side of the gas collection box is provided with a feed bin, the bottom of the feed bin is provided with a feed pipe, the feed pipe is provided with an air inlet pipe, and the end of the air inlet pipe away from the hearth extends to the inside of the gas collection box.

[0009] Further, a filter screen is installed at the connection between the hearth and the air inlet pipe, and a gas suction device is installed at the connection between the gas collection box and the air inlet pipe.

[0010] Further, the outer wall of the gas collection tank is provided with an air outlet pipe.

[0011] Further, the bending part of the L-shaped guide plate is provided with a rounded corner.

[0012] Further, the L-shaped guide plate is internally provided with molecular sieve particles, and a plurality of through holes are formed in the surface of the L-shaped guide plate.

[0013] Compared with the prior art, the utility model has the advantages that:

[0014] 1、In the utility model, gas flows into the collection tank and contacts the staggered active carbon blocks which are in a wave shape from top to bottom. The Z-shaped channel formed by the staggered arrangement greatly prolongs the gas residence time. When the gas flows along the Z-shaped channel, the L-shaped guide plate uniformly divides the gas flow into two sides, optimizes the gas distribution in the channel, and increases the contact opportunity with the active carbon blocks. The small guide plates on the top and bottom of the L-shaped guide plate accurately guide the divided gas flow to the wave-shaped recesses of the active carbon blocks. The increased contact area helps the gas to fully contact the active carbon blocks. After the gas is adsorbed by multiple active carbon blocks in the Z-shaped channel, the problem of short contact between the gas and the active carbon and poor odor removal is solved.

[0015] 2、In the utility model, the adsorption capacity of the active carbon gradually decreases after adsorbing a certain amount of odor substances. Heating the active carbon blocks by the electric heating wire can make the adsorbed odor molecules desorb from the surface of the active carbon and realize the regeneration of the active carbon. In this way, the service life of the active carbon blocks can be prolonged, and the operation cost of the device can be reduced. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0021] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0022] Please refer to Figures 1-4 The present application provides a technical solution:

[0023] Please refer to Figures 1-4 As shown in the figure, a device for removing odor during boiler sludge blending combustion, comprising a gas collection tank 1, a plurality of activated carbon blocks 2, fixedly installed on the inner wall of the gas collection tank 1, the upper and lower surfaces of the activated carbon blocks 2 are both set in a wavy shape, the plurality of activated carbon blocks 2 are staggered to form a Z-shaped Z-shaped channel 3; an L-shaped guide plate 4, fixedly installed on the Z-shaped channel 3, the shape of the L-shaped guide plate 4 is set as L-shaped; a small guide plate 5, fixedly installed on the top and bottom of the L-shaped guide plate 4, the small guide plate 5 is set in an inclined manner, and the small guide plate 5 is inclined to the wavy recess of the activated carbon block 2.

[0024] First, the gas containing odor discharged from the boiler enters the gas collection tank 1. Odor gases such as hydrogen sulfide, ammonia, volatile organic compounds, etc. generated during the boiler sludge blending combustion are all collected into this tank body for subsequent treatment.

[0025] When the gas flows in the gas collection tank 1, it will encounter a plurality of activated carbon blocks 2 staggered installed on the inner wall. The upper and lower surfaces of these activated carbon blocks 2 are wavy and staggered to form a Z-shaped channel 3. The existence of the Z-shaped channel 3 makes the flow path of the gas become tortuous, compared with the straight channel, greatly prolongs the residence time of the gas in the device.

[0026] During the gas moving along the Z-shaped channel 3, the L-shaped guide plate 4 fixedly installed on the channel plays a key role. Since the L-shaped guide plate 4 is L-shaped, when the gas hits it, the flow direction will be changed, and the originally concentrated gas flow will be evenly divided into two parts, respectively flowing to both sides of the L-shaped guide plate 4, avoiding the local gas flow speed being too fast, ensuring that the gas can be more evenly distributed in the Z-shaped channel 3, increasing the opportunity to contact the activated carbon blocks 2.

[0027] Further, the small guide plates 5 fixedly installed at the top and bottom of the L-shaped guide plate 4 also participate in the gas guiding process. The small guide plates 5 are inclined and inclined to the wavy recesses of the activated carbon blocks 2. After being shunted by the L-shaped guide plate 4, the gas flow will be further precisely guided to the wavy recesses of the activated carbon blocks 2 when encountering the small guide plates 5. Because the wavy surface of the activated carbon blocks 2 increases the surface area, the recesses further increase the contact area with the gas, and the guiding effect of the small guide plates 5 enables the gas to fully contact the surface of the activated carbon blocks 2.

[0028] The activated carbon blocks 2, with their rich pore structure and large specific surface area, physically adsorb odor gas in contact with them. For example, odor molecules such as hydrogen sulfide and ammonia are adsorbed on the surface of the activated carbon after being guided layer by layer and fully contacting the activated carbon blocks 2, thereby removing the odor from the gas. As the gas flows continuously in the Z-shaped channel 3, it is sequentially subjected to the adsorption of multiple activated carbon blocks 2, and the odor-free gas after purification is discharged from the device, thereby better solving the problem of short contact time between the gas and the activated carbon and poor odor removal effect in existing devices.

[0029] Referring to Figure 4 , the activated carbon blocks 2 are internally installed with electric heating wires 6.

[0030] The electric heating wires 6 are externally connected to a power source.

[0031] After the activated carbon adsorbs a certain amount of odor substances, its adsorption capacity will gradually decrease. Heating the activated carbon blocks 2 by the electric heating wires 6 can enable the adsorbed odor molecules to obtain sufficient energy to desorb from the surface of the activated carbon, thereby regenerating the activated carbon. This can prolong the service life of the activated carbon blocks 2 and reduce the operating cost of the device.

[0032] Referring to Figure 4 , the inclination angle of the small guide plates 5 is 15°.

[0033] The inclination angle of 15° can more ideally guide the gas shunted by the L-shaped guide plate 4 to the wavy recesses of the activated carbon blocks 2. This angle neither causes the gas to excessively deviate to one side, resulting in excessive gas flow in some areas, nor makes the gas guiding effect not obvious, thereby ensuring that the gas can uniformly and fully contact the recesses of the activated carbon blocks 2 and improving the odor removal effect.

[0034] Referring to Figures 1-2 , one side of the gas collection tank 1 is provided with a feeding bin 7, the bottom of the feeding bin 7 is installed with a feeding pipe 8, the feeding pipe 8 is installed with an air inlet pipe 10, and the end of the air inlet pipe 10 away from the hearth 9 extends to the inside of the gas collection tank 1.

[0035] The feeding bin 7 provides a convenient inlet for the boiler sludge. The operator can easily send the sludge into the subsequent processing flow through the feeding bin 7. The feeding pipe 8 can guide the sludge to be transported along a specific path, ensuring that the sludge is stably and accurately introduced into the position related to the furnace 9, realizing the mixed combustion with the fuel. The other end of the air inlet pipe 10 extends into the gas collection box 1, so that part of the gas in the furnace 9 can be introduced into the gas collection box 1.

[0036] Referring to Figures 1-2 , the filter screen 12 is installed at the connection between the furnace 9 and the air inlet pipe 10, and the air suction device 11 is installed at the connection between the gas collection box 1 and the air inlet pipe 10.

[0037] The filter screen 12 can effectively intercept solid impurities in the furnace 9, such as unburned particles, dust, etc. This not only prevents these impurities from entering the air inlet pipe 10 and the gas collection box 1, avoiding the blockage or contamination of the activated carbon block 2 and other components inside the device, affecting the odor removal effect and the normal operation of the device, but also ensures the quality of the gas entering the gas collection box 1, so that the odor gas can be more fully contacted with the activated carbon, improving the adsorption efficiency.

[0038] Referring to Figures 1-3 , the air outlet pipe 13 is installed on the outer wall of the gas collection box 1.

[0039] The air outlet pipe 13 can control the flow direction of the gas, guide the purified gas to be discharged according to the set direction, avoid the disorderly flow or accumulation of the gas in the device, and help to maintain the stability of the pressure in the gas collection box 1, ensuring the safety and stability of the device operation.

[0040] Referring to Figure 3 , the bending part of the L-shaped guide plate 4 is designed as a round corner.

[0041] The round corner design can make the airflow smoother when passing through the bending part of the L-shaped guide plate 4, avoiding the airflow vortex and turbulence caused by the right-angle bending, thereby effectively reducing the airflow resistance. This helps to maintain the stable flow of the gas in the device, ensures that the odor gas can smoothly pass through each processing link, and improves the odor removal efficiency.

[0042] Referring to Figure 3 , the L-shaped guide plate 4 is internally provided with molecular sieve particles, and the surface of the L-shaped guide plate 4 is provided with a plurality of through holes.

[0043] The molecular sieve particles have strong adsorption capacity and can adsorb water molecules and part of small molecule odor substances in the odor gas. When the odor-containing gas passes through the through holes on the surface of the L-shaped guide plate 4 and enters its interior, the molecular sieve particles can preliminarily adsorb and purify the gas, further improving the odor removal effect of the device.
