[0002] Before the ceramic is formed, it is mixed with multiple components by wet method, and the mixed slurry is dried by spraying so that the multiple components can be uniformly combined together without separation, which leads to uneven formula and poor performance of subsequent products. The spraying process is a process of drying a large amount of water vapor, and a small amount of superfine powder and binder are discharged by induced draft during drying. The superfine powder is filtered out by a dust removal bag, and the dust removal bag is frequently blocked due to a large amount of water vapor and binder in the process, so the dust removal bag needs to be replaced regularly, and a large amount of water vapor is directly discharged into the air through the tail gas discharge port.

[0006] The filter cotton is water-resistant filter cotton.

[0007] The condenser water inlet is connected with an external cooling water inlet pipe, and the condenser water outlet is connected with a cooling water return pipe.

[0008] The filter is internally provided with filter cotton.

[0009] The outlet pipeline enters the water pool below the water level by 8-12mm.

[0010] The outlet pipeline enters the water pool below the water level by 10mm.

[0011] The water pool is a closed water pool, and an air outlet pipe is arranged on the water pool.

[0012] The condenser outlet is provided with a timing switch.

[0013] The spray tower tail gas treatment system has the advantages that the tail gas discharged from the spray tower does not contain superfine dust, binder and the like after passing through the condenser and the water pool, and the water vapor is also condensed, so that clean air is discharged.

DETAILED DESCRIPTION

[0018] The spray tower tail gas treatment system provided by the utility model will be described in detail below with reference to the drawings and in combination with an embodiment.

[0019] EMBODIMENT

[0020] Referring to Figs. 1-2 , the spray tower tail gas treatment system of the embodiment comprises a condenser 2, a condenser inlet pipe 14 connected to a spray tower 1, a condenser outlet connected to a dust removal bag 3, a condenser feeding port 8 and a condenser outlet 7 arranged at the front end of the condenser 2, a condenser water outlet 9 and a condenser water inlet 10 arranged at the middle part of the condenser 2, a condenser outlet 11 and a condenser drain 12 arranged at the rear end of the condenser 2, a filter cotton and a valve arranged in the condenser feeding port 8, filter cotton arranged in the condenser outlet 11, an induced draft fan 4 connected to the rear end of the dust removal bag 3, a filter 5 arranged on the outlet pipeline of the induced draft fan 4, and the outlet pipeline connected to the water pool 13 below the water level of the water pool 13 by 8-12 mm.

[0021] The filter cotton is water-resistant filter cotton.

[0022] The condenser water inlet 10 is connected to an external cooling water inlet pipe, and the condenser water outlet 9 is connected to a cooling water return pipe.

[0023] The filter 5 is internally provided with filter cotton for secondary dust removal and water removal.

[0024] The outlet pipeline enters the water pool 13 below the water level by 8-12 mm.

[0025] The outlet pipe enters the water level of the pool by 10mm, and the depth will affect the exhaust port pressure.

[0026] The pool 13 is a closed pool, and the pool 13 is provided with an air outlet pipe 6, and the air outlet pipe port is a filtered tail gas discharge port.

[0027] The condenser discharge port 7 is provided with a timing switch.

[0028] The condenser of the embodiment is divided into three parts:

[0029] The first part is the bower ring area, and the condenser feeding port is provided with a bower ring. The bower ring has the advantages of high pass rate, high barrier and high contact area. When the water vapor carrying dust passes through the bower ring area, it will first pass through a coarse sieve type filter, leaving dust and part of the water vapor in this area. The condenser discharge port is provided with a timing switch, and the generated water vapor and dust are continuously discharged from this port. The water vapor is the main component of the tail gas, and the superfine dust is the secondary component. During use, the self-generated water vapor will form self-cleaning on the dust adhered to the bower ring. After a long time, a high-pressure spraying device can be added at the condenser feeding port valve to periodically clean the internal bower ring without disassembly and cleaning. The high-pressure spraying device can be selected as a high-pressure water vapor spray gun.

[0030] The second part is a tube type condenser, which can use a conventional metal condenser on the market. The heat exchange area is between 1-3 square meters per 50 liters of evaporation capacity.

[0031] The third part is filter cotton, which is installed at the outlet of the condenser. There is a condenser drain port in the middle for regular drainage. The water produced in this part comes from the water vapor cooled by the condenser and the water vapor filtered by the filter cotton.

[0032] The tail gas carrying superfine dust and binder discharged from the spray tower is treated by the condenser and then passes through the pool, and no longer contains superfine dust, binder, etc. The water vapor is also condensed, and the discharged air is clean.
