Description
Technical field
The present invention relates to a kind of exhaust heat recovering method and device that reclaims in the acetone process, the method and apparatus that the waste heat that particularly adopts absorption method that airborne trace acetone is carried out producing in the removal process reclaims.
Background technology
Acetone is solvent commonly used in the industrial processes, contain trace acetone in the air that discharge in production equipment and workshop, the air that contains trace acetone is called pending gas, the acetone that reclaims in the pending gas adopts the fixed bed active carbon adsorption more, its advantage is acetone rate of recovery height, purifies back tail gas content of acetone and can be low to moderate below the 40ppm; Shortcoming is that steam consumption is higher relatively.Retracting device of the prior art has 10 adsorbent beds, 5 adsorbent beds are 1 group, adopt 2 groups of parallel connections, the operation of single group circulating rolling, the work of every adsorbent bed is divided into two processes in the retracting device, be adsorption process and resolving, adsorption process is that the acetone in the pending gas is adsorbed on the adsorption stuffing, thus acetone and air; Resolving is by the Steam Heating adsorbent bed, and the temperature of adsorbent bed is raise, and then the acetone evaporated on the adsorption stuffing and being blended in the steam, along with steam breaks away from adsorption stuffing in the lump.
For example, illustrate that below in conjunction with Fig. 12 in 5 adsorbent beds (1 group) are the course of work of adsorbent bed 10 and 10 ' in the existing apparatus, these 5 adsorbent beds are arranged in turn, adopt the 4+1 operational mode, namely the beginning maintains 4 beds and is in the samsara mode of operation that adsorbed state, 1 bed are in parse state in 1 group.When adsorption process begins, open simultaneously and go out air-valve 40 on air intake valve 30 on the pending gas blast pipe 31 of adsorbent bed 10 and the discharge pipe 41, pending gas a enters from the top of adsorbent bed 10, and tail gas b discharges from the below, enters atmosphere by exhaust passage 20; After absorption is finished, close air intake valve 30 and go out air-valve 40, open inlet valve 50 on the steam inlet duct 51 of adsorbent bed 10 and the gas outlet valve 60 on the escape pipe 61 simultaneously and switch to resolving, high-temperature steam c enters from adsorbent bed 10 belows, separates gassing d and discharges from the top; After finishing, resolving switches to adsorption process again; The adsorbent bed 10 but time independent operating of a stagger resolving identical with the adsorbent bed 10 ' course of work.
In resolving, make the acetone and water (pending gas the is brought into) desorption that are adsorbed in the filler, must satisfy the required intensification of desorption and heat of gasification, need timesharing, respectively common 125t filler and 225t adsorbent bed bed body in 10 adsorbent beds be heated to high temperature; When switching to adsorbed state after parsing is finished, again by pending gas cooled to low temperature.Be example with this device, 10 about 17.8t/h(0.35Mpa of the total steam consumption quantity of adsorbent bed resolving, 180
0C).It is about 58.7% that measuring and calculating accounts for total operation quantity of steam through the heat of exhaust emissions, and this also is the high reason place of absorbing process energy consumption.Since this exhaust emissions be discontinuity and temperature mainly be air (only switch and contain part steam in the tail gas early stage) when falling progressively the fast and discharging of speed, lack effective recuperation of heat means, cause a large amount of thermal waste.
