Abstract

The utility model discloses a vacuum device of a monoammonium phosphate double effect concentration system. The vacuum device comprises a mixed condenser, a circulating water liquid seal trough, a cool water tower collecting tank and a circulating water pump. A drain pipe of the mixed condenser is communicated to the bottom of the circulating water liquid seal trough, a U-shaped liquid feeding pipe arranged at the bottom of the cool water tower collecting tank is communicated with the upper part of the mixed condenser, and a circulating pipe and the circulating water pump are arranged between the circulating water liquid seal trough and the cool water tower collecting tank. An overflow pipe is arranged on the cool water tower collecting tank, and a valve is installed on a water outlet pipe horizontally arranged and communicated with the U-shaped liquid feed pipe at the bottom of the cool water tower collecting tank. According to the vacuum device of the monoammonium phosphate double effect concentration system provided by the utility model, by the adjustment of the opening degree of the valve, the vacuum degree of the double effect concentration system and the concentration effect of the double effect concentration system can be effectively improved, and overlarge steam consumption can be further avoided, so that the steam is saved.

Description

Monoammonium phosphate two is imitated the concentration systems vacuum unit
Technical field
The utility model relates to a kind of monoammonium phosphate two and imitates the concentration systems vacuum unit.
Background technology
Produce monoammonium phosphate and adopt slurry concentrated process technology, imitating concentration systems for monoammonium phosphate two is to rely on vacuum tightness to concentrate, and the regulation and control of against vacuum degree require than higher.
Former MAP Plant two is imitated the vacuum unit of concentration systems; Water cooling tower water collecting basin bottom has pipeline to communicate with the cool condenser of mixing top through liquid pipe under the U-shaped; Upflow tube on the water cooling tower water collecting basin also with U-shaped under the liquid pipe communicate; Water cooling tower water collecting basin recirculated water gets into the cool condenser of mixing through liquid pipe under the U-shaped steam condensate of two effect concentration systems is cooled off, thereby imitates the certain vacuum tightness of manufacturing in the flashing chambers two.Because imitating the steam condensate of concentration systems, cooling two needs a large amount of recirculated water; Therefore water cooling tower water collecting basin bottom has pipe diameter very big; General diameter reaches 350mm, and advantage is can guarantee to get into the cooling water inflow that mixes cool condenser, guarantees the vacuum tightness of two effect systems.Shortcoming is to guarantee that the water cooling tower water collecting basin has enough moisture storage capacitys; Otherwise can cause the water yield can not full packages in pipeline, its upper end can get into air, and gets into through liquid pipe under the U-shaped and to mix cool condenser; Cause the vacuum tightness of two effect concentration systems to reduce, influence the concentrated effect of two effect concentration systems; And water cooling tower water collecting basin moisture storage capacity is too much, and unnecessary recirculated water can overflow from upflow tube, and the liquid pipe gets into and mixes cool condenser under U-shaped, consumes more quantity of steam.
In order to solve the not high problem of bringing of vacuum tightness, the MAP Plant that has is set up water-ring vacuum pump above mixing cool condenser, and the shortcoming consumes electric power and the EER of this method are very low.
Summary of the invention
The purpose of the utility model is to the weak point that exists in the prior art, provides a kind of monoammonium phosphate two to imitate the concentration systems vacuum unit, can effectively improve the vacuum tightness of two effect concentration systems.
The utility model has adopted following technical scheme: comprise mixing condenser, recirculated water liquid seal trough, water cooling tower water collecting basin and water circulating pump; The liquid discharge pipe of mixing condenser passes to recirculated water liquid seal trough bottom; Water cooling tower water collecting basin bottom has that the liquid pipe communicates with mixing condenser top under the U-shaped; Between recirculated water liquid seal trough and the water cooling tower water collecting basin circulating pipe and water circulating pump are arranged; The water cooling tower water collecting basin is provided with upflow tube, and valve is equipped with in being on the horizontally disposed rising pipe that the liquid pipe communicates under water cooling tower water collecting basin bottom and the U-shaped.
Through the aperture of regulated valve, can guarantee that the recirculated water of valve inlet is in the full packages state all the time, can avoid the air admission mixing condenser, therefore can improve the vacuum tightness of two effect concentration systems.
A preferred version of the utility model is: the upflow tube lower end on the water cooling tower water collecting basin communicates with the recirculated water liquid seal trough.Unnecessary recirculated water does not get into mixing condenser, but directly returns in the recirculated water liquid seal trough, can not consume the steam that gets in the mixing condenser.
Can know by technique scheme; The utility model only needs on the rising pipe of water cooling tower water collecting basin bottom, to increase by one valve; Through the aperture of regulated valve, can effectively improve the vacuum tightness of two effect concentration systems, improve the concentrated effect of two effect concentration systems; The steam consumption that can also avoid causing is excessive, practices thrift steam.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1, water cooling tower water collecting basin 9 bottoms have and are horizontally disposed rising pipe 7, and valve 8 is housed on the rising pipe 7, and rising pipe 7 the other ends communicate with mixing condenser 1 top through liquid pipe 6 under the U-shaped; Two imitate steam 2 feeds from mixing condenser 1 bottom, and mixing condenser 1 bottom has liquid discharge pipe 3 to pass to recirculated water liquid seal trough 4 bottoms, and the recirculated water in the recirculated water liquid seal trough 4 carries out fluid-tight to liquid discharge pipe 3; Circulating pipe 10 and water circulating pump 11 are arranged between recirculated water liquid seal trough 4 and the water cooling tower water collecting basin 9, and water cooling tower water collecting basin 9 tops have upflow tube 5 to communicate with recirculated water liquid seal trough 4.
Principle of work is following: the recirculated water in the water cooling tower water collecting basin 9 gets into mixing condenser 1 through rising pipe 7 and valve 8 liquid pipe 6 under U-shaped, imitates steam 2 to two and carries out cooling liquid, and imitate the certain vacuum tightness of manufacturing in the flashing chamber two.Water coolant in the mixing condenser 1 and is transported to water cooling tower water collecting basin 9 internal cooling through water circulating pump 11 and circulating pipe 10 in liquid discharge pipe 3 flows to recirculated water liquid seal trough 4.Recirculated water unnecessary in the water cooling tower water collecting basin 9 directly returns in the recirculated water liquid seal trough 4 through upflow tube 5.Through the aperture of regulated valve 8, can guarantee that the recirculated water of valve inlet is in the full packages state all the time, can avoid the air admission mixing condenser, therefore can improve the vacuum tightness of two effect concentration systems.
