Description

Technical Field

[0001] The present application relates to the field of multi-stage collection structures for denitrification ammonia escape detectors, and in particular, to a multi-stage collection structure for denitrification ammonia escape detectors. Background Art

[0002] The denitrification process uses a reducing agent (liquid ammonia, ammonia water, urea, etc.) to produce a reduction reaction with nitrogen oxides in the flue gas, reducing the nitrogen oxides in the flue gas into non-toxic and non-polluting nitrogen and water. The treated flue gas needs to be detected in real time using a denitrification ammonia escape detection device.

[0003] The structure of the product can refer to the ammonia escape laser analyzer disclosed in Chinese patent document CN206891958U. The utility model uses a programmable controller PLC set in an empty space in a rectangular box to play a control role, and connects the pins on the PLC with switches, capacitive touch screens, filters, thermostats, heaters, infrared ammonia analyzers and back-blowing blowers with wires. Then, the valves in the rectangular box are calibrated, and the sample gas enters the heating pipeline through the inlet, passes through the valve, and comes to the filter. The filter filters the sample gas to remove impurities, and the filtered sample gas is controlled by the thermostat and heater to adjust the temperature.

[0004] The above structure has the problems of lack of a multi-stage sampling and collecting structure for flue gas state and a simple and inefficient overall structure. Utility Model Content

The content of this application is not intended to identify the key features or essential features of the technical solution claimed for protection, nor is it intended to limit the scope of the technical solution claimed for protection.

[0006] In order to solve the technical problems mentioned in the above background technology part, some embodiments of the present application provide a multi-stage collection structure for a denitrification ammonia escape detector, including an equipment box assembly, characterized in that: a flue gas heating and conveying assembly is provided on the top of the equipment box assembly, a driving and conveying assembly is provided inside the flue gas heating and conveying assembly, a flue gas multi-stage collection and detection assembly is connected to one side of the driving and conveying assembly, a flue gas discharge valve component is provided at the bottom of the flue gas multi-stage collection and detection assembly, a denitrification ammonia detector is provided at both ends of the top of the flue gas multi-stage collection and detection assembly, a data sampling tube is connected to the top surface of the flue gas multi-stage collection and detection assembly at one end, a data display is connected to one side of the data sampling tube, the flue gas multi-stage collection and detection assembly includes a U-shaped flue gas heating pipe, two-way valve A and two-way valve B are connected to the left and right side surfaces of the U-shaped flue gas heating pipe at the top edge, a two-way valve C is provided at the bottom of the U-shaped flue gas heating pipe, and sealing tubes are provided at the left and right side edges of the top surface of the U-shaped flue gas heating pipe, and a gas sampling straw is passed through the inside of each of the sealing tubes.

[0008] Furthermore, a smoke inlet is provided on the left side surface of the equipment box A near the bottom edge, and a heating plate A is covered on the right side surface of the equipment box A.

[0009] Furthermore, a sealing frame is provided on the top of the equipment box A, a smoke conveying pipe is provided inside the equipment box A, and a hot air hole is opened on one side surface of the sealing frame near one end edge.

[0010] Furthermore, the smoke heating and conveying assembly includes an equipment box B, the top of which is covered with a heating plate B, and an internal heat display screen is provided at the center of the front end surface of the equipment box B.

[0011] Furthermore, a delivery valve A is provided at the center of the right end surface of the equipment box body B, and a hot air pipe is provided at one side of the center of the right end surface of the equipment box body B.

[0012] Furthermore, the driving and conveying assembly includes a driving motor, and a blower blade is provided on the top of the driving motor.

[0013] Furthermore, an S-shaped smoke conveying pipe is provided on the top of the blower blade, and a conveying valve B is provided at one end of the S-shaped smoke conveying pipe.

[0014] The beneficial effect of the present application is that it provides a multi-stage collection structure for a denitrification ammonia escape detector that can collect data through multi-stage and multiple detections with low energy consumption and low detection cost.

[0015] By setting up an equipment box assembly, the smoke is transported to the interior and continuously sucked by the driving and conveying assembly on the top through the smoke conveying pipe to continue to be transported to the smoke multi-stage collection and detection assembly for multi-stage detection. The heating plates arranged on the outside of the equipment box assembly and the smoke heating and conveying assembly perform compensatory heating on the air inside the equipment. The energy consumption is low and the detection cost is low. Denitrification ammonia detectors are set at the smoke inlet and outlet on the left and right ends of the top of the smoke multi-stage collection and detection assembly to perform the first detection on the incoming smoke, and then it is heated by the internal U-shaped smoke heating tube and detected again by the second detector. The two different data are all transmitted to the data display, and the data is maintained by intermittent detection. In addition, the gas sampling straw arranged on the top can absorb the internal gas at any time for other sampling uses.

[0016] By arranging heating plates within the equipment box assembly and the flue gas heating and conveying assembly structure, the internal pipeline can be externally heated and the internal air can be compensatorily heated, with low energy consumption and low detection cost. The sealing frame is used to connect the equipment box assembly and the flue gas heating and conveying assembly and to seal the connection. The interior is in a communicating state, and there will be no uneven internal temperature. The internal heat display screen is used to monitor the internal temperature in real time to avoid errors.

[0017] The driving motor in the driving conveying component structure drives the blower blades to convey the flue gas entering from the bottom upward. In addition, two spare flue gas exhaust valves are placed at the front end of the equipment box component. The spare flue gas exhaust valves can be connected to the sealing pipe for multi-channel exhaust. The stop valve is used to control the valve switch automatically. The data sampling tube is connected to two denitrification ammonia detectors to collect the detected data in real time and keep it on the data display. BRIEF DESCRIPTION OF THE DRAWINGS
