Description

Technical Field

[0001] The utility model relates to the technical field of flue gas treatment, in particular to a centralized collection and treatment device for environmentally friendly dust reduction flue gas from a furnace group. Background Art

[0002] A coking furnace is a device used to decompose coal by coking. It is an important device in the coking process. It decomposes coal into coke and coke oven gas at high temperature by isolating the air. Waste gas and smoke will be generated in the process of coking coal by the coking furnace. If the waste gas and smoke are not handled in time, they will pollute the atmosphere. Therefore, the smoke generated by the furnace group must be collected and treated.

[0003] At present, the flue gas treatment process generated in the coking furnace is mostly to pass the flue gas into a soluble liquid, dissolve the pollutants and smoke in the flue gas into the soluble liquid, and achieve flue gas treatment. However, there will be problems such as the flue gas staying in the solution for too short a time and the dissolution effect is poor.

[0004] For example, a device for collecting and treating flue gas from a furnace group for environmental protection dust reduction disclosed in Chinese patent CN215539694U effectively solves the problem of dissolving the flue gas and breaking the gas to increase the dissolution efficiency by arranging a collecting and treating bin, an exhaust pipe, an air inlet pipe, a ventilation elbow, a partition and a stirring rack; effectively solves the problem of sufficiently breaking and separating the gas so that the gas and the solution are fully contacted and mixed so that the flue gas is fully dissolved by arranging a bubble splitting plate, a stirring rod and a stirring blade; effectively solves the problem of timed treatment of the sediment in the sedimentation cylinder by arranging a sealing valve and a rotating scraper; and the structure is simple and stable, with extremely high universality.

[0005] However, the flue gas entering the treatment device will form bubbles in the solution and then float vertically upward, so that the contact time with the solution is still very short, making it difficult to ensure the dissolution effect.

[0006] Therefore, we urgently need to provide a centralized collection and treatment device for dust reduction flue gas from a furnace group with a long flue gas residence time. Utility Model Content

[0007] The purpose of the utility model is to provide a centralized collection and treatment device for dust reduction of a furnace group so as to solve the problem in the above-mentioned background technology that the flue gas entering the treatment device will form bubbles in the solution and then float vertically upward, so that the contact time with the solution is still very short, making it difficult to ensure the dissolution effect.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a furnace group environmental protection dust reduction flue gas centralized collection and treatment device, including a treatment box and a support column, the support column is fixedly connected to the four corners of the lower side of the treatment box, an air intake pipe is fixedly connected to the middle position below the left end of the treatment box, the front side of the treatment box is hinged with a box door by a hinge, the inner and outer ends of the treatment box are connected to a treatment mechanism, the treatment mechanism includes a treatment unit and an opening and closing unit, the treatment unit is arranged at the inner and outer ends of the treatment box, and the opening and closing unit is arranged at the middle position on the right side of the front end of the treatment box.

[0010] A further improvement is that air inlet holes are provided at equal distances at the lower end of the air inlet pipe, so that the smoke entering the air inlet pipe will be discharged from the air inlet holes into the solution in the treatment box.

[0011] A further improvement is that the left partition plate and the right partition plate in the treatment box are fixed to the inner side of the treatment box in an alternating manner, so that the bubbles formed by the smoke entering the bottom of the treatment box will pass through the solution between the left partition plate and the right partition plate in sequence and slowly rise, so that the smoke stays in the solution for a longer time, which is enough to fully dissolve the harmful substances in the smoke.

[0013] A further improvement is that a limiting hole is provided in the middle of the support plate and the middle of the upper end of the support frame, and the outer side of the insertion rod is slidably connected to the inner side of the limiting hole. Thus, when the spring drives the fixing ring to move, the insertion rod can be driven to slide along the inner side of the limiting hole, thereby limiting the movement of the insertion rod.

The support column 2 is fixedly connected to the four corners of the lower side of the treatment box 1. An air intake pipe 3 is fixedly connected to the middle position below the left end of the treatment box 1. Air intake holes are opened at equal distances at the lower end of the air intake pipe 3. Therefore, the flue gas entering the air intake pipe 3 will be discharged from the air intake hole into the solution in the treatment box 1.

[0027] The front side of the processing box 1 is hinged with a box door 4, and the inner and outer ends of the processing box 1 are connected with a processing mechanism, which includes a processing unit and an opening and closing unit. The processing unit is arranged at the inner and outer ends of the processing box 1, and the opening and closing unit is arranged in the middle position on the right side of the front end of the processing box 1.

[0028] The processing unit includes a box cover 501, a motor 502, a rotating rod 503, a stirring blade 504, a left partition plate 505, a right partition plate 506, an exhaust pipe 507, a liquid inlet pipe 508, a liquid discharge pipe 509 and an observation window 510.

[0029] The left partition plate 505 and the right partition plate 506 in the treatment box 1 are staggered and fixed to the inner side of the treatment box 1. Therefore, the bubbles formed by the flue gas entering the bottom of the treatment box 1 will pass through the solution between the left partition plate 505 and the right partition plate 506 in sequence and slowly rise, so that the flue gas stays in the solution for a long time, which is enough to fully dissolve the harmful substances in the flue gas. Example

[0030] On the basis of the first embodiment: the opening and closing unit includes a fixed rod 601, a support plate 602, a support frame 603, a spring 604, a fixed ring 605 and an insertion rod 606, the fixed rod 601 is fixedly connected to the middle position of the right side of the box door 4, the support plate 602 is fixedly connected to the middle position of the front end of the right side of the processing box 1, the support frame 603 is fixedly connected to the upper side of the support plate 602, the spring 604 is fixedly connected to the inner top of the support frame 603, the fixed ring 605 is fixedly connected to the middle position of the outer side of the insertion rod 606, and the insertion rod 606 is fixedly connected to the inner side of the fixed ring 605. A limiting hole is provided at the middle position inside the support plate 602 and the middle position of the upper end inside the support frame 603, and the outer side of the insertion rod 606 is slidably connected to the inner side of the limiting hole.
