一种自动清洗的废气喷淋塔装置

Abstract

本申请公开了一种自动清洗的废气喷淋塔装置，包括：废气塔主体、循环水箱、加药桶、冲洗水箱；通过自动化清洗显著降低了人工进入塔内清洁的频率和作业难度，从而有效减少了人工维护成本与维护强度；同时，自动化高效清洗能及时清除沉淀物，减缓塔内构件的腐蚀和磨损，进而延长设备的整体使用寿命；此外，该自动化清洗可有效防止粉尘、粘性物及结晶物在喷淋塔喷嘴、填料层等关键部位积聚造成的系统堵塞，保障系统稳定运行；并且，通过避免结垢污染造成的气液接触效率下降，本装置得以维持并提升废气与吸收液的处理效率；清洗的时候可以不需要停机，在处理废气的同时开启清洗喷淋。

Claims

1. An automatic cleaning exhaust gas spray tower apparatus, characterized by, include: The main body of the exhaust gas tower, the circulating water tank, the chemical dosing tank, and the flushing water tank; The main body of the exhaust gas tower includes an upper exhaust gas tower layer, a grid, a middle exhaust gas tower layer, a grid, and a lower exhaust gas tower layer arranged in sequence; The lower layer of the exhaust gas tower is provided with an exhaust gas inlet, and the top and bottom of the lower layer of the exhaust gas tower are respectively provided with cleaning nozzles; The middle layer of the exhaust gas tower is equipped with PP packing, exhaust gas treatment nozzles, and cleaning nozzles; The upper layer of the exhaust tower is equipped with PP packing, exhaust gas treatment nozzles and cleaning nozzles, and is connected to the exhaust gas outlet; The lower layer of the exhaust gas tower is connected to the circulating water tank, the circulating water tank is connected to the dosing tank, the dosing tank is also connected to the flushing water tank, and both the circulating water tank and the flushing water tank are connected to cleaning nozzles and exhaust gas treatment nozzles; both the circulating water tank and the flushing water tank are also connected to tap water pipes and recycled water pipes. A circulating water pump is connected to a delivery pipeline to transport the waste gas treatment liquid in the circulating water tank to the cleaning nozzles and waste gas treatment nozzles. A differential pressure control electric valve is installed at the connection between the delivery pipeline and the cleaning nozzles. Differential pressure controllers are installed in the middle and upper layers of the waste gas tower. When the differential pressure exceeds the set range, and a large amount of waste gas accumulates in the tower, or when a large amount of dirt in the tower affects the waste gas treatment speed, the differential pressure control electric valve will automatically open to achieve automatic cleaning of the waste gas tower.

2. The self-cleaning exhaust gas spray tower apparatus of claim 1, wherein, One side of the tap water pipe and the recycled water pipe are respectively connected to the tap water pipe and the environmentally friendly recycled water pipe; the other side is divided into three paths into the circulating water tank. One path is controlled by a manual valve, which can be manually opened and closed; one path is controlled by a ball valve, which automatically opens to allow water to enter when the water level in the tank is lower than the set value; and one path is controlled by an electric valve in the water tank, which is connected to a water level sensor probe. When the water level in the tank is lower than the set value, the valve automatically opens to allow water to enter.

3. The self-cleaning exhaust gas spray tower apparatus of claim 1, wherein, The chemical delivery pipeline is controlled by a pH-controlled electric valve, which automatically adds chemicals based on the pH reading from the pH monitor at the bottom of the exhaust gas tower.

4. The self-cleaning exhaust gas spray tower apparatus of claim 1, wherein, An overflow outlet is installed at the top of the circulating water tank, which is connected to the wastewater treatment pipeline.

5. The automatic cleaning exhaust gas spray tower device according to claim 1, characterized in that, The dosing tank is stored on a support frame and contains waste gas treatment chemicals. The dosing tank is connected to two delivery pipes to deliver the treatment chemicals to the circulating water tank and the flushing water tank.

6. The self-cleaning exhaust gas spray tower apparatus of claim 1, wherein, The flushing water tank is used to store waste gas treatment liquid, including: tap water / reclaimed water and waste gas treatment chemicals; the flushing water tank is connected to the chemical input pipe, the tap water / reclaimed water pipe, and the waste gas treatment liquid output pipe; the waste gas treatment liquid output pipe is connected to the output pipe of the circulating water tank, and a valve is installed on the waste gas treatment liquid output pipe.

7. The self-cleaning exhaust gas spray tower apparatus of claim 1, wherein, During use, depending on the actual situation, the exhaust gas tower can be cleaned with the exhaust gas treatment liquid in the circulating water tank, or the exhaust gas tower cleaning liquid can be prepared in the flushing water tank, or the exhaust gas tower can be cleaned with tap water / recycled water alone.
