Description

Technical Field

[0001] This utility model relates to a distributor that can efficiently distribute desulfurizing agent, belonging to the field of flue gas treatment technology. Background Technology

[0002] Coking plants generate large amounts of nitrogen oxides and sulfur dioxide during the production process, which are major sources of air pollution, seriously endangering human health and the natural environment. Currently, various desulfurization processes can meet the emission standards for coke oven flue gas and special limit requirements, but they suffer from low reaction efficiency, high energy consumption, and high operating costs. The current industry has obvious overcapacity, coupled with very strict environmental protection requirements, which has increased the investment pressure on coking plants in desulfurization projects.

[0003] Therefore, improving the reaction efficiency of desulfurizing agents is of great significance for promoting cleaner production in the coking industry and upgrading the environmental governance of coking enterprises.

[0004] For example, Chinese utility model patent application CN201922198401.3 discloses a flue gas distributor, including a flue gas inlet housing and a flue gas distributor; the flue gas inlet housing includes a flue gas hood and a flue gas duct connected to the flue gas hood, the flue gas inlet housing has an insertion hole, the flue gas distributor includes a support pipe, a ring cover connected to the outer wall of the support pipe, a cover body, a primary distribution plate connected between the ring cover and the cover body, and a secondary distribution plate located inside the cover body; the support pipe is installed in the insertion hole, the secondary distribution plate is connected to the outer wall of the support pipe, and the bottom of the cover body has a flue gas outlet.

[0005] The flue gas distributor described above allows the flue gas to enter in a spiral shape through the inlet of the volute flue, increasing the flue gas travel and extending the flue gas residence time. Then, through the primary distribution plate and the secondary distribution plate, it ensures that the flue gas is evenly distributed when it is discharged from the outlet into the reaction tower. This allows the flue gas to fully react with the desulfurizing agent, enabling the flue gas to be desulfurized and purified, and avoiding the phenomenon of wall clogging caused by excess desulfurizing agent.

[0006] The aforementioned document proposes to improve the contact between flue gas and desulfurizing agent by changing the flue structure, thereby avoiding excess desulfurizing agent. However, this method lacks corresponding treatment and control of the desulfurizing agent, requires changes to the existing flue structure, and excessively affects the smooth discharge of flue gas. Therefore, this utility model is proposed. Utility Model Content

The side wall of the distribution housing 1 is provided with an upper inclined surface and a lower inclined surface. A discharge port is opened on the lower inclined surface, and a discharge pipe 101 is provided at the bottom of the discharge port. A mixing port is opened at the top of the distribution housing 1, and a mixing main pipe 102 is installed on the mixing port. A mixing branch pipe 103 is connected to the side wall of the mixing main pipe 102. The mixing branch pipe 103 and the mixing main pipe 102 need to be supplied with desulfurizing agent raw materials and pressurized using high-pressure equipment. A support leg 104 is fixed at the bottom of the lower inclined surface. A material distribution component 2 is installed inside the distribution housing 1. One end of the discharge pipe 101 is connected to a spray gun device 3 through a wear-resistant hose. The spray gun device 3 needs to be installed on the outer wall of the flue according to the processing requirements.

A snap-fit ​​post 105 is fixed at the bottom inside the distribution housing 1, and the bottom of the extension base 203 is rotatably snapped onto the snap-fit ​​post 105 to facilitate the fixation of the extension base 203.

[0029] like Figure 4 As shown, the spray gun device 3 includes a spray pipe 301. The outer wall of the first end of the spray pipe 301 is provided with a spray strip hole 302. The outer wall of the second end of the spray pipe 301 is fixed with a connecting flange 303. The second end of the spray pipe 301 extends downward at an angle, and the spray pipe 301 is provided with an anti-clogging pipe 304. Generally, the flue structure has a vertical section and a curved section. When installing the spray gun device 3, it is necessary to open a through hole and weld a fixed flange on the flue structure. This makes it easier to install the spray gun device 3 outside the flue.

[0030] like Figure 4 and Figure 5 As shown, the first end of the spray pipe 301 extends obliquely upward with an upward protrusion. The spray strip hole 302 is located on the upward protrusion. The second end of the spray pipe 301 has an end hole. A baffle 305 is provided outside the upward protrusion. The top of the baffle 305 is rotatably locked into the end hole by an anchor rod. This can easily adapt to the curved section structure of the flue. An external hole is provided on the outer wall of the baffle 305. A baffle blade 306 is fixed on the outer wall of the baffle 305. The baffle blade 306 can rotate under the push of the flue gas, which can facilitate the dispersion of the desulfurizing agent.

[0031] Example 2: Please refer to Figures 6-7As shown, this embodiment proposes another structure for the spray gun device 3 based on embodiment 1. It is mainly suitable for installation on the side wall of a vertical flue. The flow path of the flue gas is disturbed by the baffle 307.

A power rod 404 is fixed on one side of the drive gear 403. One end of the power rod 404 passes through the offset hole and passes through the connecting flange 303 and is connected to an external power device, which facilitates the rotation of the distal tube.

[0032] When in use, this distributor can evenly distribute the desulfurizer to multiple spray gun devices 3. First, the mixing main pipe 102 and mixing branch pipe 103 are connected to the external raw material conveying components. The desulfurizer formed by mixing can be broken and mixed, and then dispersed into each discharge pipe 101. During use, the desulfurizer enters each spray gun device 3 through the wear-resistant hose. When the spray pipe 301 is blocked, the anti-blockage pipe 304 can absorb the high pressure and blockage of the desulfurizer, and then it can be discharged to the outside to avoid equipment damage. The spray gun device 3 also helps to disperse the desulfurizer, so that the desulfurizer and flue gas can come into full contact.
