System and technology for producing coked crude phenol

The invention discloses a system for producing a coked crude phenol. The system is characterized in that a middle-lower part of a washing tower is communicated with a chimney of a tubular furnace. A phenol sodium salt tank is respectively communicated with middle-upper parts of a washing tower and a dehydration tower through a phenol sodium salt pump. An air inlet is arranged at a middle-lower part of the dehydration tower. An air outlet is arranged at an upper part of the dehydration tower. A dehydration intermediate tank is communicated with a middle-upper part of a decomposition tower through a middle pump. A lower part of the dehydration tower is communicated with the dehydration intermediate tank. An upper part of the washing tower is communicated with a middle-lower part of the decomposition tower through a decomposition tower blower fan. An air outlet is arranged at an upper part of the decomposition tower. The middle-lower part of the decomposition tower is communicated with a crude phenol tank. The b
