A wood drying equipment to eliminate the discharge of liquid kiln water includes
a kiln which is heated to dry a batch of wood, a basin to collect the water driven from the wood, and an evaporator in which the collected water is converted into steam. The steam is provided to the kiln to balance the drying and alleviate the splitting, warping, etc. caused by over drying. The steam is ultimately vented harmlessly into the atmosphere to effectively eliminate any discharge of the kiln water as a liquid.
Wood dry equipments in accordance with claim 1 which further comprises a collection basin outside of said kiln, wherein said collection basin is fluidly coupled to the kiln for receiving liquid water discharged from the kiln chamber, and to said evaporator to provide the discharged liquid water to the evaporator.
A wood drying system in accordance with claim 4 which further comprises a collection basin outside of the kiln and coupled with said kiln for receiving liquid water from said wood drying kiln chamber, said collection basin including a separator for substantially separating the water from ash which mixed with the liquid water in the kiln chamber.
The effluent produced during the wood drying equipment process or during cleaning of the kilns creates a potential environmental hazard when discharged into rivers, lakes or other natural surroundings. States have therefore begun to ban or consider banning the discharge of water from the operation of kilns into the environment. As a result, wood drying facilities are faced with the prospect of shutting down for lack of a solution to the problem of disposing of kiln water.
