specific Embodiment approach 1

[0012] Specific Embodiment 1: The northern greenhouse vegetable production system based on the comprehensive utilization of "three biogases" in this embodiment includes a greenhouse (18), a modular biogas production system and a vegetable planting system (14), and the modular biogas The production system is arranged above the ground inside the greenhouse (18), and the vegetable planting system (14) is arranged inside the greenhouse (18).

specific Embodiment approach 2

[0013] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is that the modular biogas production system is composed of a gas production unit, a warming and heat preservation unit, a biogas residue and biogas liquid separation unit, and a biogas delivery unit. The unit consists of a fermentation room (3), a feed port (2), a sample outlet pipe (8), a gas storage space (1) and a gas collection port (19). The feed port (2) is set in the fermentation room (3 ), the sample outlet pipe (8) is set under the right side of the fermentation room (3), the gas collection port (19) is set above the fermentation room (3), the gas collection port (19) and the gas transmission pipeline ( 16) Connect. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0014] Embodiment 3: This embodiment is different from Embodiment 1 or 2 in that: the temperature-increasing and heat-retaining unit is composed of a heat-retaining room (9), a heating device (4), and a heat-insulating benzene board (5). The chamber (9) is wrapped outside the fermentation room (3), the heating device (4) is arranged at the bottom of the fermentation room (3), and the heating device (4) is located above the heat-insulating benzene plate (5). Others are the same as in the first or second embodiment.

Abstract

The invention relates to a northern greenhouse vegetable production system based on comprehensive utilization of biogas residue, biogas slurry and biogas, and aims to solve the problem that utilizing rate of the biogas residue, the biogas slurry and the biogas is low, time and force are consumed, and procedures are complicated by the existing method. The northern greenhouse vegetable production system comprises a greenhouse, a modular biogas production system and a vegetable planting system. The modular biogas production system is arranged on the ground in the greenhouse and comprises a biogas generating unit, a temperature increasing and maintaining unit, a biogas residue and biogas slurry separating unit and a biogas delivering unit, and the vegetable planting system is located inside the greenhouse. The northern greenhouse vegetable production system is simple in assembling and disassembling, convenient to transport, small in occupied area, good in temperature increasing and maintaining effect and high in biogas generating efficiency, and utilizing rate of the biogas residue, the biogas slurry and the biogas reaches 100%, and the northern greenhouse vegetable production system can be applied to northern greenhouse vegetable planting.

Description

technical field [0001] The invention relates to a northern greenhouse vegetable production system based on the comprehensive utilization of "three marshes". Background technique [0002] The northern region of my country occupies an extremely important position in the national animal husbandry and grain production, and can produce a large amount of biomass resources such as crop straw and livestock manure every year. Taking Heilongjiang Province as an example, the grain output in 2012 reached 55.92 million tons, and the straw output It can reach 61.52 million tons, and the livestock and poultry fresh manure produced by livestock and poultry farming is about 110 million tons. Use livestock and poultry manure, crop stalks, kitchen waste and other wastes as biogas raw materials for anaerobic digestion, and make reasonable use of "three biogases" (biogas residue, biogas slurry, biogas), which can effectively improve the biomass of agriculture, animal husbandry, etc. energy utili...
