1. When the shell side of a horizontal heat exchanger contains a single-phase clean fluid, the gaps in the baffle plates should be arranged （ ）； When the fluid in the shell side of horizontal heat exchangers, condensers, and reboilers is in a gas-liquid mixture or contains solid particles, the gaps in the baffle plates should be arranged in a ( ) pattern, and a ( ) should be provided at the lowest point of the baffle plates. 2. The three short-circuit prevention structures recommended by the GB151 standard are: ( ) ； ( ) ； ( ). Each question has three blanks, with 1 point for each blank.
1. Horizontal and vertical arrangement； Arranged vertically left and right; liquid inlet 2. Bypass baffle; blocking tube; intermediate baffle
1. When the shell side of a horizontal heat exchanger contains a single-phase clean fluid, the gaps in the baffle plates should be arranged (horizontally, up and down)； When the fluid flowing in the shell side of horizontal heat exchangers, condensers, and reboilers is in a gas-liquid mixture or contains solid particles, the gaps in the baffle plates should be arranged vertically (left and right), and fluid passage holes should be provided at the lowest point of the baffle plates. 2. The three short-circuit prevention structures recommended by the GB151 standard are: (bypass baffle) ； (Pipe baffle) ； (Middle baffle tube).

1. Horizontal up and down, vertical left and right, fluid inlet 2. Bypass baffle, pipe baffle, middle baffle
The moderator’s question is a bit strange. This is specified on pages 73 and 78–79 of the GB151 standard: when the shell side of a horizontal heat exchanger contains a single-phase clean fluid, the gaps in the baffle plates should be arranged horizontally (up and down)； When the fluid flowing in the shell side of horizontal heat exchangers, condensers, and reboilers is in a gas-liquid mixture or contains solid particles, the gaps in the baffle plates should be arranged vertically (left and right), and a fluid inlet should be provided at the lowest point of the baffle plates. 2. The three short-circuit prevention structures recommended by the GB151 standard are: (bypass baffle) ； (Pipe stopper) ； (Middle baffle).
