Background technology
The sustainable development of agricultural must be based upon on the basis of land fertility sustainable development, singly execute the minimizing dropped into fertilizer partially to fertilize for a long time, it is the major reason causing soil fertility decline, environmental pollution and quality of agricultural product to reduce, it is solve problem of environmental pollution that the industrialization of fertilizer utilizes, promoting that fertilizer enriches, improves the new approach of quality of agricultural product, is also the needs of agricultural sustainable development.
In recent years, along with the propelling of China's modernization new countryside construction, China's agricultural is just towards specialization, mass-producing, the fast development of intensive direction.With this simultaneously, the a large amount of feces of livestock and poultry produced and crop material, the discharge of the organic wastes such as edible fungi residues causes huge pressure to ecotope again, on the other hand, along with the rise of green agriculture, the importance and functions of organic fertilizer has laid out important position in agro-ecology organic technology field, fertilizer is commonly called as farm manure, refer to containing large number of biological material, plant and animal residues, movement, the slow-release fertilizer of the materials such as biological waste, not only containing the macroelement that plant is required in fertilizer, trace element, also containing abundant organic nutrient, fertilizer is the most comprehensive fertilizer.
The fermentation mode of fertilizer mainly contains stacked, open and hermetic type alr mode, and the fermentation of no matter which kind of mode, the environment that creation aerobic bacterium is easy to breed is very important, be beneficial to condition nutritious, temperature, moisture, air, the PH of aerobic fermentation, these all need artificially to regulate and control, guarantee to be in best fermentation condition, improve the quality of fertilizer; Heat, ammonia, CO can be produced in organic aerobic fermentation treating processes
2, H
2o etc., wherein the concentration of odor pollutant ammonia is 3, about 000ppm, the water-soluble aobvious alkalescence of ammonia, be generally used for regulating pH value, and untreated animal manure is acid about PH6.0, and the active activity of PH8.0 ~ 9.0 pair bacterium is only optimal, is the problem of a needs consideration while therefore how odor pollutant ammonia being deviate from and to ammonia comprehensive utilization.
Summary of the invention
The technical problem to be solved in the present invention be for prior art lack a kind of odor pollutant ammonia can be deviate from while and to ammonia comprehensive utilization device, a kind of sealed fermenting organic fertilizer deodorization is provided to adjust pH value device, water is utilized to absorb ammonia, the ammoniacal liquor formed is for regulating the pH value in fermenter, simultaneously by improving equipment, guarantee that in fermenter, PH is equal, provides suitable yeasting to aerobic bacterium everywhere.
In order to solve the problems of the technologies described above, the invention provides following technical scheme: sealed fermenting organic fertilizer deodorization adjusts pH value device, comprise fermenter, water wash column, wood chip room, tank for sewage gas, described fermenter is hollow cylinder, top coupling has groove lid, the central position of groove lid is provided with motor, described motor has stirring rake, described stirring rake lower end is passed groove lid and is placed in fermenter inside, the uniform rotation of driven by motor stirring rake, described groove covers and is provided with air blower, platen suction nozzle is also provided with in described fermenter, be connected on foul smell pipe, described foul smell pipe is connected with foul smell blower fan through groove lid, the foul smell pipe of drawing from foul smell blower fan enters water wash column bottom water wash column, described water wash column opposite side connects wash water pipe, wash water pipe connects wash water pump, the wash water of water wash column is shunted by wash water pump after the suction of bottom, a wash water pipe passes in the middle part of water wash column, and spray wash water downwards by spray header, another root wash water pipe is communicated with stirring rake, enter in fermenter, described wash water pipe also communicates with air blower, described scrubber tower top connects purification tracheae, purification tracheae passes into wood chip chamber interior, the described wood chip room the other end connects biogas pipe, the biogas pipe the other end connects biogas blower fan, the biogas pipe of the described biogas blower fan the other end is communicated with tank for sewage gas.
Principle of work of the present invention and beneficial effect are: when using sealed fermenting organic fertilizer deodorization tune pH value device, raw material ferments in fermenter, driven by motor stirring rake Keep agitation, stirring velocity is little, a large amount of foul smell is produced in fermenting process, the major cause of livestock products stench is a large amount of ammonias, ammonia is very high to the sorbency of water, foul smell enters scrubber tower under the effect of blower fan, foul smell moves upward, and wash water is introduced in the middle part of tower top by wash water pump and sprayed downwards, wash water circulation cleaning, gas-liquid conversed flowing, wash water absorbs the NH inside foul smell
3, from top, purified gas is out passed into wood chip room and carries out double absorption, and wood chip indoor are placed with moist wood chip, make purified gas by between wood chip particle, NH
3composition is absorbed by wood chip or is dissolved by the moisture between wood chip and wood chip inherent moisture, blows for a long time, then wood chip self starts fermentation, microbial reproduction gets up, the oxidized decomposition of these microorganisms becomes odorless composition, and then promotes deodorization, and the biogas after secondary deodorizing passes in tank for sewage gas to be collected.Wash water repeatedly after washing absorbs NH
3afterwards in alkalescence, when the material PH in fermenter is lower, do not reach PH8.0 ~ 9.0, i.e. aerobic bacterium optimum pH value, be incorporated in stirring rake by the effect of wash water pump, from the passage ejection stirrer paddle, stir and spray, potential of hydrogen in regulating tank, the wash water pipe that groove covers also is communicated with air blower, when closedown wash water pipe, as required, in groove, supplement air, suitable oxygen concn is provided.
Further, described stirring rake hollow, blade is provided with multiple passage, and ammonia water and air enters in fermenter by passage, the PH in regulating tank and oxygen concn.
