Description

Technical Field

[0001] The utility model relates to a control cabinet, in particular to an atomizer control cabinet. Background Art

[0002] At present, domestic waste incineration power plants often use semi-dry deacidification centrifugal atomizers. In an atomizer system, the atomizer is installed in the desulfurization reaction tower, and the control system is matched with the atomizer to control the operation of the atomizer. The existing atomizer control system mainly includes a cabinet, a control module, an oil and gas module, and a cooling module; among them, the oil and gas module is used to mix lubricating oil and air, and then transport them to the atomizer to lubricate the transmission parts of the atomizer.

[0003] Since there are two sets of bearings in the atomizer, the oil-gas module in the existing control cabinet forms an oil-gas mixed medium, which is transported to the top of the atomizer through a main pipeline and then divided into two branches to be transported to the two sets of bearings respectively. This will cause the following problems:

[0004] When the oil-gas mixture is divided into two branches through a main pipeline, it is difficult to distribute it evenly, resulting in uneven distribution of lubricating oil in the two branches. Since the bearing speed is relatively high, the bearing with less lubricating medium distribution is prone to failure due to insufficient lubrication, which reduces the service life of the bearing. Utility Model Content

[0005] The purpose of the utility model is to overcome the above-mentioned problems and provide an atomizer control cabinet, which can provide uniform and sufficient lubricating oil for two groups of bearings, thereby being beneficial to protecting the bearings and extending the life of the bearings.

[0006] The purpose of the utility model is achieved through the following technical solutions:

[0007] An atomizer control cabinet comprises a cabinet body and an oil and gas control unit arranged in the cabinet body;

[0008] The oil and gas control unit includes an oil and gas supply mechanism, an oil and gas delivery mechanism and an oil atomization generator; the oil and gas delivery mechanism includes a delivery main pipeline and a delivery branch pipeline; the delivery branch pipeline is provided with two groups; one end of the delivery main pipeline is connected to the outlet of the oil and gas supply mechanism, and the other end of the delivery main pipeline is connected to one end of two groups of delivery branch pipelines through a delivery three-way joint; the other ends of the two groups of delivery branch pipelines are respectively connected to the lubrication inlets of the two bearing positions of the atomizer; the oil atomization generator is provided with two groups and is respectively arranged on the two groups of delivery branch pipelines.

[0009] The working principle of the above atomizer control cabinet is:

[0010] During operation, the oil and gas supply mechanism mixes the lubricating oil and air to form an oil-gas mixed medium, and outputs it to the main delivery line; the oil-gas mixed medium is respectively delivered to two groups of delivery branch pipelines through the main delivery line, and atomized by the oil atomization generator, and finally the atomized oil-gas mixed medium is delivered to the atomizer by the two groups of delivery branch pipelines. The oil atomization generator can control the amount of oil-gas lubricating medium in the corresponding delivery branch, so as to ensure that the two groups of delivery branch pipes have sufficient lubricating medium to be delivered to the corresponding bearing groups, so as to independently lubricate the two groups of bearings, which is beneficial to protecting the bearings and extending the life of the bearings.

[0011] In a preferred embodiment of the present invention, the delivery branch pipeline includes a first delivery branch pipeline and a second delivery branch pipeline;

[0012] The two ends of the first delivery branch pipeline are respectively connected to the delivery three-way joint and the inlet of the oil atomization generator, and the two ends of the second delivery branch pipeline are respectively connected to the outlet of the oil atomization generator and the atomizer.

[0013] In a preferred embodiment of the present utility model, the oil and gas control unit further comprises a waste oil recovery mechanism, which comprises a waste oil recovery tank, a waste oil recovery pipeline and a recovery drive mechanism;

[0014] The waste oil recovery pipeline includes a main recovery pipeline and a recovery branch pipeline; the recovery branch pipeline is provided with two groups; one end of the main recovery pipeline is connected to the waste oil recovery tank, and the other end of the main recovery pipeline is respectively connected to one end of the two groups of recovery branch pipelines through a recovery three-way joint; the other ends of the two groups of recovery branch pipelines are respectively connected to the lubrication outlet of the atomizer;

Through the above structure, high-pressure gas is generated by the high-pressure gas source and passed into the venturi tube. The high-pressure gas generates negative pressure in the venturi tube, and the negative pressure is transmitted to the waste oil recovery tank and the waste oil recovery pipeline through the negative pressure tube, and then the waste oil in the atomizer is extracted and new lubricating oil is injected, which can protect the transmission structure and extend the service life.

[0016] Furthermore, the inlet of the venturi tube is connected to the outlet of the gas distributor block of the oil and gas supply mechanism, and the inlet of the gas distributor block of the oil and gas supply mechanism is connected to the high-pressure gas source. In this way, a set of high-pressure gas mechanisms can be shared.

[0017] Furthermore, one end of the recovery main line is connected to the waste oil recovery tank through an oil-gas separator, so that the recovered oil-gas mixture is first separated into oil and gas to ensure that the gas finally discharged from the waste oil recovery tank into the atmosphere is clean and will not cause air pollution.

[0019] The recovery branch pipeline includes a first recovery branch pipeline and a second recovery branch pipeline; the two ends of the first recovery branch pipeline are respectively connected to the recovery tee joint and the outlet of the observation cup, and the two ends of the second recovery branch pipeline are respectively connected to the inlet of the observation cup and the atomizer. Through the above structure, dynamic bubbles can be seen in the observation cup during normal operation; if there are no dynamic bubbles, it means that the part is faulty; if the bearing is damaged, contaminated black oil will be pumped out; if an atomizer slurry return accident occurs, white slurry pollutants will be pumped out. The above situations can all be obtained from the observation cup, which is very convenient.

[0020] In a preferred embodiment of the present invention, a partition plate is provided in the cabinet, and the partition plate divides the inner cavity of the cabinet into an oil and gas cavity and a water cavity;

[0021] The oil and gas control unit is arranged in the oil and gas chamber;

Then, the water is transported to the rotor shaft and the atomizing disk of the atomizer through two flushing branch lines, and the rotor shaft and the atomizing disk are flushed respectively to flush the scale, and then enter the interior of the reaction tower after flushing; the amount of water in this process is very small, and it is directly evaporated by the high-temperature flue gas after flushing, and no recycling treatment is required. Furthermore, in terms of structure, the existing water tank is removed, and the filter module is integrated into the cabinet, which is simple and compact in structure and reduces costs.
