Abstract
The invention relates to a built-in filtration and decontamination device, which comprises a filter cartridge which is arranged in a condensation water tank, wherein the top of the filter cartridge is connected with a condensation water inlet pipe, the bottom of the filter cartridge is connected with a discharge pipe which penetrates through the condensation water tank, the filter cartridge comprises a side wall keel, a filter component is wound at the outer part of the side wall keel, and an upper annular plate and a lower annular plate are respectively welded at the top and the bottom of the side wall keel. The built-in filtration and decontamination device has the beneficial effects that: the device is purely mechanical, does not have electrical elements and has a long service life; the device is applicable to various flow working conditions; a water pump is prevented from cavitation, so the investment for changing the water pump every year is reduced; and condensation water is more conveniently recycled in a closed way, so wide popularization of an energy-saving technology is more benefited.
Description
Technical field
The present invention relates to a kind of built-in filtration decontamination apparatus, be applicable to that mainly the filtration, purification in the condensate return system is handled.
Background technology
In commercial production, steam Chang Zuowei thermal source or power source, be a kind of be with the energy very widely.After steam is emitted heat energy or work done, be converted into liquid condensate, still have higher heat energy, and quality be better, generally reclaim as boiler feedwater or alternate manner second use.
But for the condensate that reclaims, owing to carrying and use tends to sneak into iron rust, welding slag, silt or other solid particle etc., preliminary treatment such as need filter earlier, just can get into condensate return system.Traditional approach generally has dual mode: the first adds filter in Condensate recovery device water inlet pipe porch; It two is to add filter in condensate pump import department.But all there is drawback in this dual mode: add filter at the recover inlet, because condensed water in high temperature generally is emulsification attitude, i.e. steam water interface; Steam is taken and is being wrapped up in drop and pass through filter; Water hammer can take place, cause filter screen will damage at short notice, do not have filtration; And the y-type filter that adds on the pipeline, because the structural restriction of itself, filter area is less; Filtering accuracy is not high, and as improving filtering accuracy, resistance is just too big; Particularly at condensate pump suction inlet place, resistance increases, for the higher condensate of temperature; Be easy to generate vaporization phenomenon, cause condensate pump impeller cavitation.
Summary of the invention
Be technical deficiency more than solving, the invention provides a kind of being located in the condensate recycling can, can effectively filter, the built-in filtration decontamination apparatus that purifies water condensed water in high temperature.
The present invention realizes through following measure:
A kind of built-in filtration decontamination apparatus of the present invention; Comprise the cartridge filter that is arranged in the water pot that condenses; Said cartridge filter top is connected with the condensate water inlet pipe, and the bottom is connected with the blow-off pipe that passes the water pot that condenses, and cartridge filter comprises the sidewall keel; Said sidewall keel are surrounded with filter assemblies outward, and sidewall keel top and bottom are welded with upper ring plate and lower ring plate respectively.
Above-mentioned filter assemblies is wedge shape sintered filter core or one or more layers stainless steel cloth or orifice plate.
Above-mentioned filter assemblies outside is wound with some roads stainless steel band, and is provided with stainless steel bolt.
Above-mentioned blow-off pipe is L shaped, and top is connected with lower ring plate is vertical, and terminal horizontal is extended the water pot that condenses.
The invention has the beneficial effects as follows: pure machinery, no electrical equipment, the life-span is long; Be suitable for various flow operating modes; Prevent pump cavitation, reduced the annual more investment of water-change pump; Enclosed reclaims to make condensate reclaim more easily, more advantageously promotes power-saving technology on a large scale.

Description of reference numerals:
1 condense water pot, 2 water inlets, 3 built-in water separators, 4 cartridge filters, 5 sewage draining exits, the outlet of 6 flash steams, 41 upper ring plates, 42 filter assemblies, 43 sidewall keel, 44 lower ring plates, 45 blow-off pipes, 46 condensate water inlet pipes, 47 stainless steel bands.
The specific embodiment
Like Fig. 1,2,3, shown in 4; A kind of built-in filtration decontamination apparatus of the present invention comprises the cartridge filter 4 that is arranged in the water pot 1 that condenses, and cartridge filter 4 tops are connected with condensate water inlet pipe 46; The bottom is connected with the blow-off pipe 45 that passes the water pot that condenses; Cartridge filter 4 comprises sidewall keel 43, the sidewall keel 43 outer filter assemblies 42 that are surrounded with, and sidewall keel 43 tops and bottom are welded with upper ring plate 41 and lower ring plate 44 respectively.Filter assemblies 42 is wedge shape sintered filter core or one or more layers stainless steel cloth or orifice plate.Filtering accuracy is decided according to designing requirement.Filter assemblies 42 comes off when preventing backwash, is provided at an outer portion with multiple tracks stainless steel band 47, and fixes with stainless steel bolt, can dismounting and change.
Blow-off pipe 45 is L shaped, top and 44 vertical connections of lower ring plate, and terminal horizontal is extended the water pot 1 that condenses.
Operation principle of the present invention is: condensed water in high temperature at first gets into built-in water separator 3 through water inlet 2, and the condensate after separating through carbonated drink enters into cartridge filter 4 from condensate water inlet pipe 46, and flash steam is discharged from flash steam outlet 6.Enter in the water pot 1 that condenses after filter assemblies 42 filtrations of condensate through cartridge filter 4 sidewalls.In filter process, solid particle is filtered assembly 42 and holds back, and accumulates impurity more for a long time when filtering on the assembly 42; Open the blowoff valve of Condensate recovery device, the sewage draining exit 5 and the atmosphere of blow-off pipe 45, the water purification reverse flow is in cartridge filter 4 in the water pot that condenses; Under the effect of inside and outside differential pressure, water flow velocity is very fast, accumulates in impurity on the filter assemblies 42 and is stripped from and comes off; Discharge with current, reach the purpose of filtering scrubbing.Because adopt cylinder side wall to filter, area of passage is bigger, can improve filtering accuracy; Filtration capacity is bigger, and the cycle of operation is longer; Regularly blowdown also can be according to the inlet outlet pressure differential blowdown, and is easy to operate.And because inside has keel to support, and the outside has stainless steel band 47 fastening, high pressure resistant washing away, the life-span is longer.
The foregoing description is said to be in order to specify this patent; Though describe through specific term in the literary composition; But can not limit the protection domain of this patent with this; The personage who is familiar with this technical field can change or revise it after the spirit of understanding this patent and principle and reach equivalent purpose, and this equivalence change and modification all should be covered by the claim scope and define in the category.
