AI Technical Summary
Existing hydraulic ash removal systems consume large amounts of water and have low efficiency. When ash and slag are mixed with water, they lose their loosening properties, and the high calcium oxide content easily forms scale that clogs the ash pipes. Furthermore, the mixing of ash removal water and ash and slag is not conducive to discharge and treatment.
Design a simple ash water tank, including a sedimentation tank, an inlet distribution channel, an ash water reuse channel, and a circulating water pump. The ash water is treated by sedimentation in the sedimentation tank, and the supernatant is reused by the circulating water pump. It is connected to the boiler dust collector and ash ditch to prevent siltation. A scum baffle is installed to separate scum and clear liquid.
It reduces water consumption for ash removal, improves treatment efficiency, solves the problem of ash and water mixing hindering discharge, and achieves pollution-free emissions and water conservation in boiler rooms.

DETAILED DESCRIPTION
[0014] The utility model will be described in detail below in combination with the drawings.
[0015] As Figure 1 , Figure 2 shown, a simple ash water pool used in a boiler room, including the sedimentation tank 4, the sedimentation tank 4 both ends are equipped with water inlet distribution channel 1 and ash water recycling channel 7 respectively, water inlet distribution channel 1 is connected with water inlet pipe 11, and water inlet distribution channel 1 channel wall is provided with a plurality of water distribution holes 2, and water distribution hole 2 is located at the bottom of water inlet distribution channel 1, and water inlet distribution channel 1 is communicated with sedimentation tank 4 through water distribution hole, and the overflow communication between sedimentation tank 4 and ash water recycling channel 7 is through the partition wall 12 therebetween, and circulating water pump 8 is arranged in ash water recycling channel 7, and the output end of circulating water pump 8 is connected with water outlet pipe 13.
[0016] The sedimentation tank 4 is provided with a scum baffle 6, the scum baffle 6 is close to the partition wall 12 and is arranged along the partition wall 12, and the scum baffle 6 is located at the upper end position of the partition wall 12.
[0017] The ash water recycling channel 7 is connected with an overflow pipe 10.
[0018] The ash water recycling channel 7 is connected with a water supplement pipe 9.
[0019] The water outlet pipe 13 is connected to the boiler dust collector through a first recycling pipeline.
[0020] The water outlet pipe 13 is connected to the boiler dust collector through a first recycling pipeline.
[0021] The wet dust collector discharges the ash water to the ash channel, the ash channel is provided with a certain slope, the ash water is guided to flow into the water inlet distribution channel 1 through the water inlet pipe 11, and then the ash water enters the sedimentation tank 4 through the water distribution holes 2. The sedimentation tank 4 has a large volume, so that the flow rate of the ash water is reduced, the ash water is subjected to a sedimentation reaction in the sedimentation tank 4, the ash is deposited at the bottom of the sedimentation tank 4, and the supernatant is overflowed into the ash water recycling channel 7. The supernatant is intercepted by the scum baffle 6 in the sedimentation tank 4. The clear water in the ash water recycling channel 7 is sent into the first recycling pipeline and the second recycling pipeline through the circulating water pump 8 and the water outlet pipe 13 respectively, the water in the first recycling pipeline enters the boiler dust collector, the water absorbs the flue dust and sulfur therein, becomes the ash water and flows into the ash channel, and the water is recycled repeatedly, so that the water is saved; the water in the second recycling pipeline flushes the ash channel, so that the ash channel is prevented from being silted up.
[0022] The dust collector and the sedimentation tank 4 have great evaporation loss of water, and the water is also lost during the ash removal, therefore, in order to maintain the normal operation of the circulating water pump 8 and the simple ash water tank, water needs to be supplemented, the water is supplemented through the water supplementing pipe 9, so that the water balance is maintained.
[0023] However, if the boiler drainage capacity is too large and exceeds the highest water level of the circulating water pump 8, the water will overflow through the overflow pipe 10, and the overflowed water is discharged to the outdoor rainwater system.
[0024] The simple ash water tank is provided with two groups, when the ash deposited at the bottom of the sedimentation tank 4 reaches a certain position, the ash water is switched to another sedimentation tank 4, and the ash is removed.
