Embodiment Construction
[0020] The present invention will be described in further detail below in conjunction with specific examples, and the specific examples described here are only used to explain the present invention, and are not intended to limit the present invention.
[0021] Example: Taking a high-efficiency energy-saving reactor as an example, prepare 2.5 tons of wheat straw, a clean pulping process at atmospheric pressure and low temperature, including five steps of cutting grass and removing dust, entering the reactor, screening and refining, bleaching and extruding the finished pulp ,first step
[0022] First, cut grass and remove dust, add it to the reaction kettle, and add pulping aids for the first time. The added amount is 200kg of sodium hydroxide with a purity of 100%, 2kg of green oxygen with a solid content of 96%, and a Baume degree of 37.5° 300kg of Bé's sodium silicate, 300kg of 27.5% hydrogen peroxide and 4kg of DTPA.
[0023] Next, within 30-40 minutes, the reactor decompos...
