Description
Technical field
The present invention relates to a kind of waste disposal plant, the gas, liquid, solid triphase separator using in especially a kind of anerobic sowage biochemical treatment.
Background technology
" three-phase " in so-called triphase separator refers to gas, liquid, solid (being also biogas, sewage, particle or the floc sludge during anerobic sowage is processed), abroad gas one solid separators (being called for short GSS) that are called on document more.
Triphase separator major function has two:
1) biogas that collection produces from the reaction chamber under triphase separator, avoids biogas bubble to rise to the settling region on triphase separator;
2), for the settling region on triphase separator forms good sedimentation environment, make the settling region sedimentation that particle (or cotton-shaped) mud can be on triphase separator, thereby and be smoothly through triphase separator and return to the reaction zone under triphase separator.
Along with the develop rapidly of anaerobic technology, occurred polytype triphase separator in engineering practice in recent years, wherein the most representative is the triphase separator that adopts multilayer del gas-collecting chamber structure, as shown in Figure 1 and Figure 2.
This triphase separator is to use at present more (as Chinese patent application 200910095697.4, Chinese patent ZL201020631706.5), but some problems of its existence:
(1) when current are through gap between del because overflow section diminishes, water, biogas, mud floc particle form three-phase mixed solution upflow velocity herein and can increase, and because this gap is also the decline passway of solid phase sedimentation simultaneously, thereby cause solid phase subsiding movement to be affected, cause solid particle (or cotton-shaped) mud inferior separating effect.(see figure 3)
(2) for reducing flow velocity, need to increase the space between del collection chamber, the height that simultaneously increases trilateral collection chamber and the number of plies (seeing Fig. 1, Fig. 2) on the one hand, need on the other hand to strengthen the area of triphase separator horizontal section, increase so on the one hand the production cost of triphase separator, also caused on the other hand the increase of anaerobic reactor sectional area and the increase of construction cost.
The triphase separator using in engineering now, the backflow that enters (rising) and mud (decline) of its three-phase mixture, institute, by being all the same passage of flowing through, does not have independently mud decline passway, therefore the phase mutual interference (see figure 3) that has upwelling and downwelling in service.Wherein in Fig. 3, each label implication is: sludge settling district 12, mud katabatic drainage is to 13, solid, liquid two-phase mixed solution flow to 14, biogas flow to 15, reaction zone 16, gas, solid, liquid three-phase mixed solution flow to 17, upwelling and downwelling is at this same passage 18 of flowing through, the effluent stream after gas, solid separation is to 19.
Shown in Chinese patent ZL 98242484.1(Fig. 4) a kind of Combined three-phase separator disclosed, its solid, liquid two-phase mixed solution rises, and to enter the decline passage that reaction zone flows through that refluxes back of negative area and mud (solid phase) be same passage.The effect of the gas collection plate that this patent is overlapping is to make the gas overflowing not enter filtration chamber, but because solid, liquid two-phase mixed solution upwards flows by the gap between two gas collection plates, and the mud (solid phase) of the chamber of being filtered under holding back also needs to flow downward by this gap while returning to (under triphase separator) reaction zone, therefore, can unavoidably cause solid phase subsiding movement to be subject to the impact of upward water flow flow velocity, cause solid particle (or cotton-shaped) mud inferior separating effect.And filtration chamber is comprised of silk screen, light filter material layer, dividing plate etc., easily results in blockage.
Summary of the invention
The object of the invention is the technological deficiency existing in above-mentioned triphase separator for solving, all the flow through design concept of same passage of the backflow that enters (rising) and mud (decline) that changes its three-phase mixture from design concept; From design performance, independently mud decline passway and independent negative area have been obtained, solve solid phase subsiding movement in current triphase separator and be subject to the impact to flow rate of water flow, a difficult problem for solid phase particles (or cotton-shaped) mud inferior separating effect, thereby greatly improved the mud-water separation effect of three separators.Invent a kind of individual layer del collection chamber and can realize the function that the gas, liquid, solid three phase separation that multilayer del collection chamber could realize was set in the past.The present invention is simple in structure, and cost is low, and manufacture, installation and easy to maintenance are applied widely, is convenient to the realization of maximizing.
For achieving the above object, the present invention adopts following technical proposals:
The gas, liquid, solid triphase separator using in a kind of anerobic sowage biochemical treatment, comprise some individual layer del collection chambers, described each individual layer del collection chamber medullary ray below is equipped with a pair of isometric L-type flow deflector that is splayed layout, and the L-type flow deflector length of described adjacent monolayer del collection chamber below is unequal, wherein, the L-type flow deflector that length is longer is called the long flow deflector of L-type, and the shorter L-type flow deflector of length is called the short flow deflector of L-type; Between described adjacent two short flow deflectors of L-type and the long flow deflector of L-type, form a complete independent sludge settling region; Gap between the inwall of L-type flow deflector top and trilateral collection chamber is the passage that the solid, liquid two-phase sewage mixed solution after degassed enters sludge settling region; Gap formation between L-type short flow deflector lower end and the long flow deflector of adjacent L-type and the autonomous channel of the sludge reflux of independent sludge settling regional connectivity.
The top of described each individual layer del collection chamber is equipped with vapor pipe.
The angle at the top of described each individual layer del collection chamber is 20-120 degree.
Two length of sides of described each individual layer del collection chamber are 400mm-1500mm.
The upper end of described L-type flow deflector and described trilateral collection chamber relative edge's slant range is the 20%-40% of described relative edge's length of side.
The upper end of described L-type flow deflector extend in described trilateral collection chamber, and the vertical range of bottom, the both sides of the upper end of flow deflector and described trilateral collection chamber line is 100mm-500mm.
