Description

Technical Field

[0001] This utility model relates to the field of coking equipment technology, specifically to an ammonia water filtration device. Background Technology

[0002] The coke oven gas collection system includes riser pipes, bridge pipes, and gas collecting pipes. The riser pipe at the top of the coke oven is connected to the gas collecting pipe via the bridge pipe, cooling the coal gas produced in the coke oven and guiding it into the gas collecting pipe. Low-pressure ammonia water is sprayed into the bridge pipe to cool the raw coal gas from the riser pipe from 600-650℃ to below 100℃, while at the same time causing some of the tar and ammonia water to condense down.

[0003] The ammonia water system is crucial for the stable operation of a coke oven. However, the presence of impurities such as tar in the ammonia water can easily clog the ammonia water nozzles. While anti-clogging nozzles have been developed and initially effective in preventing clogging, clogging still occurs after a period of operation, impacting coke oven production. Utility Model Content

[0004] To overcome the shortcomings of the prior art, this utility model provides an ammonia water filtration device to filter ammonia water and effectively prevent impurities in the ammonia water from clogging the ammonia water nozzle.

[0010] Furthermore, one end of the outer cylinder is a tapered section, and a gasket is fixed inside the tapered section. The inlet branch pipe extends into the support cylinder, and the gasket is located at the connection between the inlet branch pipe and the support cylinder, serving a sealing function.

[0011] Furthermore, the support cylinder and the outer cylinder are connected by a flange.

[0012] Furthermore, the other end of the support cylinder is connected to the outlet pipe.

[0013] Furthermore, pressure gauges are installed on both the inlet and outlet branches.

[0014] Furthermore, there are two filters, one in operation and one on standby.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1) The ammonia inlet and outlet pipes of this utility model are connected to a filter via inlet and outlet branch pipes. The filter removes impurities such as tar from the ammonia water, preventing nozzle clogging and ensuring stable and smooth coke oven production.

[0031] like Figure 1-4 As shown, an ammonia water filtration device includes an ammonia water inlet pipe 1, an inlet branch pipe 6, a filter 4, a cleaning pipe 3, an outlet branch pipe 8, and an ammonia water outlet pipe 9.

[0032] In this embodiment, there are two filters 4, symmetrically arranged on both sides of the ammonia inlet pipe 1. The ammonia inlet pipe 1 is divided into two symmetrical inlet branches 6, which are connected to the two filters 4 respectively. The two symmetrical outlet branches 6 merge into one ammonia outlet pipe 9.

[0033] One end of the inlet branch pipe 6 is connected to the ammonia inlet pipe 1, and the other end is connected to the filter 4. One end of the outlet branch pipe 8 is connected to the filter 4, and the other end is connected to the ammonia outlet pipe 9. One end of the cleaning pipe 3 is connected to the ammonia inlet pipe 1, and the other end is connected to the filter 4.

[0034] A cleaning valve 2 is installed on the cleaning pipe 3. An inlet valve 5 is installed on the inlet branch pipe 6, and an outlet valve 7 is installed on the outlet branch pipe 8.

[0035] like Figure 2 As shown, the filter 4 includes an outer cylinder 43 and a support cylinder 46 disposed inside the outer cylinder. Both the support cylinder 46 and the outer cylinder 43 are cylindrical with vertical axes and the same axes.

[0036] The top of the outer cylinder 43 is a tapered section 41. The inner diameter of the support cylinder 46 is slightly larger than the outer diameter of the inlet branch pipe 6. The bottom end of the inlet branch pipe 6 extends into the top of the support cylinder 46. The gasket 42 is fixed to the inner wall of the tapered section 41, located at the top of the support cylinder 46, at the connection between the inlet branch pipe 6 and the support cylinder 46, and serves as a seal.

[0037] The cleaning pipe 3 is connected to the left side wall of the outer cylinder 43, and the outlet branch pipe 9 is connected to the right side wall of the outer cylinder 43. Pressure gauges 10 are installed near the filter 4 on both the inlet branch pipe 6 and the outlet branch pipe 9.

[0038] Both the outer cylinder 43 and the support cylinder 46 are provided with flanges 44 at their bottom ends, and the bottom of the outer cylinder 43 and the support cylinder 46 are connected by flanges 44.

[0039] The bottom of the support cylinder 46 is connected to the outlet pipe 49 via a tapered tube 47, and an outlet pipe valve 48 is provided on the outlet pipe 49.

[0040] like Figure 3 , Figure 4 As shown, the support cylinder 46 has openings on its side wall, which can be circular or elongated.

[0041] A filter screen 45 is fixed to the outer wall of the side wall of the support cylinder 46.

[0042] There are two filters, one in operation and one on standby. The standby function is achieved by closing the cleaning pipe valve 2, inlet pipe valve 5, and outlet pipe valve 7 on the same side.

[0043] The working principle and process of this utility model are as follows:

[0044] When filter 4 is in operation, close the opposite side cleaning valve 2, inlet pipe valve 5, and outlet pipe valve 7, close the same side cleaning valve 2, open the same side inlet pipe valve 5 and outlet pipe valve 7, and introduce ammonia water to achieve the filtration function.

[0045] When the pressure difference detected by pressure gauge 10 is too large, open the inlet valve 5 and outlet valve 7 on the opposite side, close the inlet valve 5 and outlet valve 7 on the same side, open the cleaning valve 2 on the same side to perform cleaning, and at the same time open the outlet valve 48 to send the cleaning ammonia water along with impurities to the tank area for purification, so as to achieve continuous filtration of ammonia water.

[0046] This invention uses filter 4 to filter ammonia water, removing impurities such as tar, thus preventing nozzle clogging and ensuring stable and smooth coke oven production. Simultaneously, a cleaning pipe 3 is provided to clean filter 4, significantly extending its filtration cycle and restoring its filtration quality.
