TECHNICAL FIELD
[0001] The application relates to the field of recycling cleaning technology, in particular to a denitration catalyst module recycling cleaning structure. BACKGROUND
[0002] The denitration catalyst is mainly used in emission sources such as thermal power plants and industrial boilers. Its main function is to convert nitrogen oxides in flue gas into harmless substances through specific chemical reactions, thereby reducing the pollution caused by nitrogen oxides to the environment.
[0003] During the operation of the denitration catalyst, dust, fly ash and other loose deposits may be deposited on the surface of the catalyst, which may cause the catalyst to be blocked and affect its catalytic effect. Through cleaning, these deposits can be effectively removed to prevent blockage. The existing cleaning mechanism and drying calcination mechanism of the denitration catalyst are inconsistent in working time. After each batch of denitration catalyst is cleaned, the next batch of denitration catalyst can be cleaned only after the previous batch of denitration catalyst is dried and calcined, which increases the time cost. CONTENT OF THE INVENTION
[0004] The application aims to provide a denitration catalyst module recycling cleaning structure to improve the problem of high time cost.
[0005] The denitration catalyst module recycling cleaning structure provided by the application adopts the following technical scheme:
[0006] The denitration catalyst module recycling cleaning structure comprises a drying device located between the cleaning mechanism and the drying calcination mechanism. The drying device comprises a drying frame, and support rods are fixedly connected around the drying frame. Two support rods near the cleaning mechanism and two support rods near the drying calcination mechanism are each provided with a mounting plate. One of the mounting plates is provided with a connecting plate above it. The connecting plate is provided with a mounting hole penetrating through it. A positive pressure source part is arranged in the mounting hole. The air outlet of the positive pressure source part is located on one side close to the drying frame.
[0007] By adopting the above technical scheme, the drying device is added between the cleaning mechanism and the drying calcination mechanism, which can shorten the time. After the denitration catalyst is cleaned, it can be dried in the drying device, and the next batch of denitration catalyst can be cleaned without waiting for the previous batch of denitration catalyst to be dried and calcined before cleaning the next batch of denitration catalyst, thereby improving the efficiency. Moreover, the water in the drying device evaporates quickly, and the corresponding drying calcination time is shortened.
[0008] Optionally, the connecting plate and the mounting plate are in sliding connection.
[0009] By adopting the technical scheme, the connecting plate and the mounting plate are in sliding connection, the positive pressure source part can dry the denitration catalysts of different batches after cleaning, when the positive pressure source part dries some denitration catalysts, the connecting plate moves on the mounting plate to dry a new batch of cleaned denitration catalysts. In addition, the denitration catalysts can be dried everywhere, the residence time of the positive pressure source part in a certain place is controlled, so that the drying effect and efficiency are improved.
[0010] Optionally, the mounting plate is provided with a sliding groove with an opening upward; and a plurality of magnetic members magnetically attracted to the connecting plate are uniformly arranged on the upper end surface of the mounting plate.
[0011] By adopting the technical scheme, the mounting plate is provided with the sliding groove, and the magnetic members are arranged on the upper end surface of the mounting plate, so that the connecting plate can be positioned.
[0012] Optionally, the lower end of the positive pressure source part is provided with a funnel-shaped wind cover.
[0013] By adopting the technical scheme, the funnel-shaped wind cover designed at the lower end of the positive pressure source part makes the airflow smoother when passing through, reduces the turbulence of the airflow and the loss of energy, ensures that the generated wind force is more concentrated, and improves the efficiency of the positive pressure source part.
[0014] Optionally, a water collecting groove body is arranged below the drying rack.
[0015] By adopting the technical scheme, the design of the water collecting groove body can collect the water of the drying, so that the water cannot directly flow on the ground to cause the ground to be wet and slippery.
[0016] Optionally, a drain port is arranged on the bottom wall of the water collecting groove body; a water pump is arranged on the outer wall of the water collecting groove body, a water suction end of the water pump is in communication with the drain port, a water discharge end of the water pump is connected with a drain hose, and a water bucket is in communication with the drain hose.
[0017] By adopting the technical scheme, the design of the drain port on the upper end surface of the water collecting groove body makes the water of the drying be discharged in time through the drain port and cannot be accumulated in the water collecting groove body. The design that the lower end of the drain port is in communication with the drain hose makes the water in the water collecting groove body be discharged to other places through the drain hose instead of directly flowing on the ground through the drain port to cause the ground to be wet and slippery. The design that the drain hose is in communication with the water bucket makes the water be poured out through the water bucket when the water accumulates to a certain degree.
[0018] Optionally, a fixed groove in communication with the drain port is arranged on the bottom wall of the water collecting groove body, and a filter screen is fixedly arranged in the fixed groove.
[0019] By adopting the technical scheme, the design of the filter screen in the fixed groove avoids impurities from entering the water collecting groove body to cause the drain hose to be blocked.
[0020] Optionally, the filter screen is provided with a supporting ring around the filter screen, which is matched with the fixing groove.
[0021] By using the above technical scheme, the supporting ring is just clamped in the fixing groove, so that the filter screen is not easy to move, and in addition, the design of the supporting ring plays a better filtering role, and impurities cannot enter the drain hose from the gap.
[0022] In summary, the present application has the following beneficial technical effects of the denitration catalyst module recycling and cleaning structure:
[0023] 1. By adding a drying device in the cleaning mechanism and the drying calcination mechanism, the time can be shortened, and the denitration catalyst can be dried in the drying device after cleaning, and the next batch of denitration catalyst can be cleaned, without waiting for the previous batch of denitration catalyst to be dried and calcined before cleaning the next batch of denitration catalyst, thereby improving the efficiency, and the water in the drying device is dried quickly, and the corresponding time of the drying calcination is also shortened;
[0024] 2. The connecting plate and the mounting plate are in sliding connection, and the positive pressure source part can dry the denitration catalyst cleaned in different batches, and when the positive pressure source part dries some denitration catalyst, the connecting plate moves on the mounting plate to dry the denitration catalyst cleaned in a new batch. In addition, the denitration catalyst can be dried everywhere, and the residence time of the positive pressure source part in a certain place is controlled, thereby improving the drying effect and efficiency;
[0025] 3. The supporting ring is arranged around the filter screen, and the supporting ring is just clamped in the fixing groove, so that the filter screen is not easy to move, and in addition, the design of the supporting ring plays a better filtering role, and impurities cannot enter the drain hose from the gap.
