Description

Technical Field

[0001] This utility model relates to the field of raw coal gas treatment technology, specifically a device for the graded and quality-differentiated utilization of raw coal gas. Background Technology

[0002] Raw coal gas refers to coal gas containing dust, which cannot be directly supplied to users and must undergo dust removal treatment. This is because the furnace dust in the raw coal gas may not only clog pipelines during transportation, but also, due to the alkaline substances in the furnace dust, may fuse with acidic refractory materials under high-temperature conditions during combustion, thereby reducing the performance and service life of equipment such as coke oven combustion chambers and hot blast stove regenerators. The degree of dust removal depends on the user's requirements and technical and economic feasibility. In addition, users also have certain requirements for the moisture content and temperature of the coal gas after dust removal.

[0003] For example, patent document CN 214300017 U discloses a graded and graded utilization device for raw coal gas, including a hydrogen production unit, a pressurization unit, a desulfurization unit, a deoxygenation unit, a pressure swing adsorption (PSA) unit, and an ammonia synthesis unit connected in sequence. The inlet of the hydrogen production unit is connected to a pyrolysis furnace to perform water washing, pretreatment, enrichment, deoxygenation, and purification of the raw coal gas to produce hydrogen. The inlet of the pressurization unit receives the purified desorbed gas generated during the purification stage of the hydrogen production unit, and the pressurization unit can pressurize the purified desorbed gas to a preset pressure value. The desulfurization unit can perform fine desulfurization of the purified desorbed gas, and the deoxygenation unit can perform fine deoxygenation of the purified desorbed gas. The PSA unit is equipped with an adsorbent to remove carbon monoxide and carbon dioxide, and the outlet of the PSA unit flows out product gas. The ammonia synthesis unit can synthesize ammonia from the hydrogen and nitrogen in the product gas. This graded and graded utilization device for raw coal gas realizes the graded and graded high-value utilization of raw coal gas.

[0004] However, in practice, due to its structural limitations, this structure can only be used for the graded and graded utilization of raw coal gas by cooperating with multiple sets of equipment. This results in a large overall processing equipment size and an inability to perform more efficient continuous processing of raw coal gas. At the same time, the equipment cannot be quickly disassembled and maintained in individual areas, which cannot meet the daily usage needs. Therefore, it is urgent to design a graded and graded utilization device for raw coal gas to solve the above problems. Summary of the Invention

[0005] The purpose of this utility model is to provide a graded and graded utilization device for raw coal gas, in order to solve the problem mentioned in the background art that, in actual operation, the existing structure is limited by its own structure and can only perform graded and graded utilization of raw coal gas with the cooperation of multiple sets of equipment. This results in a large overall processing equipment size and an inability to perform more efficient continuous processing of raw coal gas. At the same time, the equipment cannot perform quick disassembly and maintenance operations on individual areas, and cannot meet the needs of daily use.

[0012] Preferably, the conveyor rack and conveyor seat are adapted to the separator and grading seat.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This raw coal gas grading and quality-separating utilization device, through its conveying frame, conveying seat, control frame, grading seat, discharge valve seat, control pump, circulation valve seat, guide valve seat, guide pipe, conveying trough, and discharge mesh trough, enables the equipment to perform more efficient raw coal gas grading and quality-separating utilization operations. In actual use, the operator first stacks the multi-group grading seats between the upper and lower conveying seats of the conveying frame. Then, the raw coal gas is input from the guide valve seat and guide pipe of the top conveying seat, and then flows downward along the conveying trough and discharge mesh trough. During the flow, in conjunction with the layer-by-layer circulation valve seat inside the control pump, the raw coal gas can be conveyed layer by layer to the interior of each grading seat. In each grading seat, grading and quality-separating utilization processing is carried out. The processed products are discharged from the discharge valve seat on the front of the grading seat. The raw coal gas then returns to the conveying frame through the control frame to be conveyed to the next layer, improving the equipment's processing efficiency for raw coal gas and demonstrating the practicality of the equipment design.

[0014] This raw coal gas grading and quality-separating utilization device further improves the overall efficiency of the equipment through the setting of a conveying frame, conveying seat, control frame, partition plate, grading seat, fixing plate, and plug-in seat. In daily use, the staff can fix the partition plate layer by layer on the front and back of the control frame through the fixing plate. Then, the grading seat can be installed layer by layer between the upper and lower conveying seats through the partition plate and the fixing plate. The back of the grading seat is connected to the front of the control frame through the plug-in seat. In the future, when there is an internal maintenance problem in a certain layer of the grading seat, it can be quickly disassembled and maintained, which reflects the comprehensiveness of the equipment design.
