Description
Technical field
The present invention relates to a kind of water tank for flushing gypsum, be applicable to the wet fuel gas desulfurizing technology gypsum dehydration system.
Background technology
In the limestone-gypsum wet fuel gas desulfurizing technology, in order to make desulfuration byproduct-gypsum obtain comprehensive utilization, when vacuum belt dewaterer was to gypsum dehydration, the water that utilization has been washed behind the filter cloth washed gypsum, to remove impurity and the chloride ion content in the gypsum.In the vacuum belt dewatering system of at present external and domestic design; substantially adopted the filter cake flush box of conical lower section; in actual motion; because a variety of causes causes the water that has washed filter cloth to be mixed with the part gypsum usually in collection process; be deposited on the conical surface of water tank bottom after entering water tank for flushing gypsum; very easily stop up the delivery port that is located at the bottom; cause the filter cake flush water pump to move; gypsum can not get flushing; influence the comprehensive utilization of gypsum, and increased field operator's workload.Directly adopting process water can the resolution system blocking problem, but has increased the intrasystem water yield, and is influential to the water balance of whole system.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of water tank for flushing gypsum, makes filter cloth washing water obtain recycling, reduces the technology water consumption; And can prevent that stopping up appears in locking system, reduced operations staff's workload.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of water tank for flushing gypsum, this water tank bottom are horizontal planes, directly are installed on building floor or the basis, ground; Be provided with agitator in this water tank.
Described agitator adopts the jacking-type agitator, and the axle of this agitator is positioned at water tank inside center position, and mixing arm is fixed on the axle, blade centre-to-centre spacing bottom half 300mm.
This tank box sidewall is provided with gypsum flush water pump inlet, and this gypsum flush water pump inlet is positioned at 50mm place on the described mixing arm.
This tank top center is provided with the perforate that is used for fixing and supports described agitator.
This water tank material adopts PPR (a kind of plastic pipe), carbon steel lining scale or carbon steel line with rubber.
This water tank sidewall is provided with manhole door, is used for to box house anticorrosion and agitator parts and safeguards.
This water tank sidewall bottom is provided with evacuation port, emptying casing when this evacuation port is used for the water tank maintenance.
This water tank lower sidewall is established the liquid-level switch interface, and this liquid-level switch interface is used to install the liquid level testing element, when liquid level is lower than setting value, sends alarm signal.
This is provided with overfall more than water tank sidewall highest working water level, and when high water tank surpassed the maximum functional liquid level, water can drain into trench by this overfall.
The invention has the beneficial effects as follows: the bottom design of water tank for flushing gypsum of the present invention is a horizontal plane, and non-traditional conical lower section, and adopted the scheme of belt stirrer in design, water flushing gypsum behind the utilization flushing filter cloth, fresh water (FW) obtains recycling, improve the utilization rate of fresh water (FW), reduced the technology water consumption; Also solved simultaneously water tank for flushing gypsum bottom blockage problem, the gypsum rinse-system can steady in a long-term move, and the gypsum quality has had assurance, has created advantage for the comprehensive utilization of gypsum, has alleviated operations staff's workload simultaneously.
Description of drawings
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments:
Fig. 1 is the structural representation of facing of water tank for flushing gypsum of the present invention;
Fig. 2 is the plan structure schematic diagram of water tank for flushing gypsum of the present invention;
Among Fig. 1 and Fig. 2: 1-water tank for flushing gypsum; 2-agitator; 3-perforate; 4-flushing water inlet; 5-gypsum flush water pump inlet; 6-ball-cock assembly interface; 7-overfall; 8-evacuation port; 9-liquid-level switch interface; 10-exhaust outlet; 11-manhole door.
The specific embodiment:
As depicted in figs. 1 and 2, water tank for flushing gypsum of the present invention adopts cylindrical, and the bottom is a horizontal plane, is supported on the corresponding flooring of building or directly is installed on the basis, ground.Be provided with agitator 2 in the water tank for flushing gypsum 1, agitator 2 adopts the jacking-type agitators, and the axle of this agitator 2 is positioned at water tank inside center position, the vanes fixed of agitator 2 on axle, the about 300mm of blade centre-to-centre spacing bottom half.After increasing agitator 2, prevent that by stirring solid particle from depositing at bottom half to the gypsum flushing water.Perforate 3 is located at the center, case top of water tank for flushing gypsum 1, is used for fixing and supports agitator 2; Flushing water inlet 4 is located at the casing top, and flushing water enters in the case from this flushing water inlet 4; Gypsum flush water pump inlet 5 is located at wall box and is positioned at 50mm place on the blade of agitator 2, and enter the mouth 5 quantity of gypsum flush water pump is provided with and can designs as required, without any restriction; Consider that the gypsum flushing water is in long-term whipping process, have the part solid particle and be deposited on around the bottom half,, be easy to generate the inlet blocking problem if gypsum flush water pump inlet 5 is lower, therefore in design, raise the position of gypsum flush water pump inlet 5, efficiently solved the problems referred to above.Ball-cock assembly interface 6 is located at wall box, is used to control high water tank, and when water level reaches when preestablishing water level, valve is closed automatically, and valve was opened moisturizing automatically when water level descended; Overfall 7 is located at more than the wall box highest working water level, and when fortuitous event occurring, when liquid level surpassed the maximum functional liquid level in the water tank, water can drain into trench by the overfall connecting pipe; Evacuation port 8 is located at the wall box bottom, emptying casing when being used for the water tank maintenance; Liquid-level switch interface 9 is located at the wall box bottom, is used to install the liquid level testing element, when liquid level is lower than setting value, sends alarm signal; Exhaust outlet 10 is located at the case top, because flushing water has uniform temperature, exhaust outlet 10 is communicated with atmosphere in time gets rid of hot gas in the case, prevents that the case internal pressure is too high; Manhole door 11 is located at wall box, is used for to box house anticorrosion and maintenance, changes the parts of agitator 2.
This water tank for flushing gypsum material can adopt PPR (a kind of plastic pipe), carbon steel lining scale or carbon steel line with rubber.This water tank for flushing gypsum is mainly used in the gypsum dehydration technology of wet process of FGD, creates favorable conditions for improving the long-term continous-stable operation of gypsum quality and system.
