Reactor for making grass pulp

The utility model is a reacting kettle, which uses the straw like wheat straw, rice straw as the raw material and makes the straw pulp by the reacting of hydrogen peroxide and alkaline substances, comprising a kettle body (1), a motor (2) and a speed change mechanism fixed on the kettle body (1), an axle (4) which are installed in the kettle body (1) and whose top is connected with the speed change mechanism, a rotator of the high density hydrapulpter (5) installed on the axle(4) and which is close to the bottom of the inner kettle body(1), a vapor-liquid supplying tube (6) whose one end is arranged into the kettle body (1) and at the bottom of the rotator of the high density hydrapulpter (5), and the other end stretched out of the kettle body (1) and is provided with a feeding valve(7)of caustic soda, a feeding valve (8) of hydrogen peroxide, a stem valve (9). When agitating, the material at the bottom is lift and agitated by the rotator of the high density hydrapulpter (5). The utility model is characterized in that the agitating is fully stable and safely, can meet the production needs of making straw pulp by the process of fierce reaction when using the straw as the raw material.
