(The title of this issue is taken from page 61 of "Technical Worker Job Training Question Bank - Soda Ash Production Operator". The electronic version of the book is available for download in the soda ash information sharing area. http://bbs.hcbbs.com/thread-13140-1-2.html ) Fill in the blanks 1. The principle of vacuum filtration is to use the action of a vacuum machine to pump ( ) into the filter to form two sides ( ) of the filter medium to separate liquid and solid. 2. The amount of crude alkali required per ton of alkali is ( ) of the burning rate. 3. The ammonia absorption of the mother liquor is a ( ) reaction, and the ( ) adjustment is used to control the amount of ammonia absorption.

1. The principle of vacuum filtration is to use the action of a vacuum machine to draw (negative pressure) inside the filter, forming a pressure difference (pressure difference) on both sides of the filter medium to separate liquid and solid. 2. The amount of crude alkali required per ton of alkali is the (reciprocal) of the firing rate. 3. The ammonia absorption of the mother liquor is an (exothermic) reaction, and (temperature) regulation is used to control the amount of ammonia absorption.

1. The principle of vacuum filtration is to use the action of a vacuum machine to draw (negative pressure) inside the filter, forming a pressure difference (pressure difference) on both sides of the filter medium to separate liquid and solid. 2. The amount of crude heavy alkali required per ton of alkali is the (base) of the firing rate. 3. The ammonia absorption of the mother liquor is an (exothermic and reversible) reaction, and (temperature control) adjustment is used to control the amount of ammonia absorption.

Reference answer 1. The principle of vacuum filtration is to use the action of a vacuum machine to draw (negative pressure) into the filter, forming a pressure difference on both sides of the filter medium to separate liquid and solid. 2. The amount of crude alkali required per ton of alkali is the (reciprocal) of the firing rate. 3. The ammonia absorption of the mother liquor is an (exothermic) reaction, and (temperature) adjustment is used to control the amount of ammonia absorption.
