The steam source box 1 is communicated with the steam inlet main pipe 5 through a steam source valve 8; the steam inlet main pipe 5 is communicated with an inlet of the still kettle 7 through a steam inlet branch pipe 10 and a steam pressure regulating valve 9 (see the attached figure 1 in the specification). The steam pressure regulating valve 9 is a conventional device, and has a function of regulating the flow rate of a medium by controlling the opening degree of an opening/closing member in a valve body to reduce the pressure of the medium, regulating the opening degree of the opening/closing member by the action of the post-valve pressure to maintain the post-valve pressure within a certain range, and maintaining the outlet pressure within a set range when the inlet pressure is constantly changed.
The tail gas outlet of the still kettle 7 is communicated with a steam outlet main pipe 6 through a steam outlet branch pipe 11 and a steam outlet valve 12 (see the attached figure 1 in the specification); when the still kettle 7 works, the discharge of the still kettle can be controlled by the steam outlet valve 12.

The upper end of the main cylinder 19 is communicated with a steam drum 20; the steam drum 20 communicates with the steam inlet manifold 5 via its own steam outlet and the steam supplementing valve 18 (see figure 1 of the specification). The steam drum 20 has the function of storing steam, and the steam generator 2 can provide boosting steam for the autoclave 7 through the steam supplementing valve 18, the steam inlet main pipe 5 and the steam inlet branch pipe 10 when in operation.
The steam drum 20 is connected with a safety valve 24 (see the attached figure 2 of the specification). When the steam pressure in the steam pocket 20 is higher than the safety pressure during operation, the steam is actively exhausted, so that the purpose of protecting the steam pocket 20 can be achieved, and the problem of 'burst' of the steam pocket 20 due to overlarge internal pressure is avoided.
The sealing partition plates 23 are symmetrically and fixedly arranged in the main cylinder 19; a plurality of heat exchange tubes 25 are arranged between the sealing partition plates 23 in a specification shape; a water replenishing valve 21 is connected on the main cylinder 19 between the sealing plates 23; the water replenishing valve 21 is communicated with an external water source (see the attached figure 2 in the specification); in operation, an external water source can provide desalted water for the steam generator 2 through the water replenishing valve 21.
Two ends of the main cylinder 19 are respectively and fixedly provided with a seal head 22; the seal head 22 at one end of the main cylinder 19 is communicated with a switch valve A13 through a heating inlet of the seal head (see the attached figures 1 and 2 of the specification); the head 22 at the other end of the main cylinder 19 is connected with a steam outlet valve 14 through a heating outlet of the head 22 (see the attached figures 1 and 2 of the specification).

The temperature sensors 15 corresponding to the pressure pump a31 and the pressure pump B32 can detect the indoor temperatures of the static stop room 29 and the pre-curing room 28; the operating power of the booster pump A31 and the booster pump B32 is controlled (see the description and the attached figure 3).
The booster pump a31 and the booster pump B32 are located outside the static chamber 29: the purpose of so setting is: the problem that the service life of the pressure pump A31 and the pressure pump B32 is influenced when the pressure pump A31 and the pressure pump B32 are in the high-temperature environment of the static chamber 29 for a long time is solved.
In the initial state of the mixing tank 30, a certain amount of circulating water must be injected into the mixing tank to avoid the "idling" of the pressurizing pump B32 and the pressurizing pump a 31.
The upper end of the mixing tank 30 is provided with an overflow pipe 42 (see the description attached to fig. 3). Because the tail gas of the still kettle can be continuously supplemented into the water mixing tank 30 during the operation, the liquid level in the water mixing tank 30 can be continuously increased, and when the liquid level in the water mixing tank 30 is increased to a certain height, the liquid level can overflow into an external water system through the overflow pipe 28 and can be reused after being treated by the external water system.

A steam stop plate 41 is fixedly arranged in the cylinder body 34 at one side of the steam inlet 36 in an inclined manner through a support plate 40 (see the description and the attached figure 4). The purpose of the vapor barrier 41 is to: when the tail gas of the still kettle is introduced into the steam distributing cylinder body 34 through the steam inlet 36, the tail gas can be directly sprayed on the steam blocking plate 41, and the spraying direction is changed under the action of the inclined surface of the steam blocking plate 41; therefore, the problem that the exhaust steam is directly injected to the steam-distributing cylinder body 34 to damage the steam-distributing cylinder body 34 can be avoided.
The pipeline between the discharge valve 17 and the switch valve C16 is provided with a blow-down valve 4 (see the description and the attached figure 4). The purpose of setting the emptying valve 4 is as follows: so that during operation, this waste heat utilization equipment accessible atmospheric valve 4 can evaporate the still cauldron tail gas and carry out urgent evacuation to when avoiding this waste heat utilization equipment to take place the accident, evaporate the problem that the still cauldron tail gas takes place not to have a place to discharge.
The working method of the device for utilizing the waste heat of the tail gas of the autoclaved sand aerated block brick comprises the following steps:
