Embodiment 1）

[0016] See Figure 1-3 , The continuous recovery and delivery device for high-temperature steam condensate in this embodiment includes: a main cylinder 1, a secondary cylinder 14, an intake switching valve 20 connected to a high-pressure gas source, and an exhaust switching valve 21 connected to the atmosphere. Both the main cylinder body 1 and the auxiliary cylinder body 14 are provided with water inlet one-way valves 17, 18 and water outlet one-way valves 13, 19. As an optimized solution, the main cylinder body 1 and the auxiliary cylinder body 14 are wrapped with an insulating layer.

[0017] The first outlet of the air intake switching valve 20 is connected to the secondary cylinder 14 through the high-pressure air pipe 16 , and the second outlet of the air intake switching valve 20 is connected to the main cylinder 1 .

[0018] The auxiliary cylinder body 14 is provided with a float type exhaust valve 15, which is closed when the liquid level in the auxiliary cylinder bo...

Embodiment 2

[0034] The working method of the continuous recovery conveying device of the high-temperature steam condensate in the above-mentioned embodiment 1, it comprises the following steps:

[0035] A. When the first lower valve of the intake switching valve 20 and the second upper valve of the exhaust switching valve 21 are closed, the first upper valve of the intake switching valve 20 and the exhaust switching valve 21 When the second lower valve is in the open state, the water inlet check valve 17 on the main cylinder 1 is opened by the high-temperature fluid and flows into the high-temperature fluid. Under the action of the gas, it is discharged through the water outlet check valve 19; the floating ball 10 in the floating ball valve opening and closing control mechanism in the main cylinder 1 gradually rises, driving the floating ball connecting rod 11 around its bottom end from bottom to top Gradually rotate and rise. When the floating ball connecting rod 11 is in line with the l...

Embodiment 3

[0038] As a modification of Embodiment 1, the control device includes: liquid level gauges arranged in the main cylinder and the auxiliary cylinder, and a controller connected to each liquid level gauge, and the inlet and exhaust switching valves are connected with the control The electric control valve connected with the device to realize the function of the control device.

[0039] As a further optional solution, the water inlet and water outlet one-way valves on the main cylinder and the auxiliary cylinder are electronically controlled one-way valves connected with the controller, and the high-pressure air source is canceled at this time.

Abstract

The invention relates to a continuous recovering and conveying device for high temperature steam condensate, which comprises a main barrel, an auxiliary barrel, a gas inlet switching valve and a gas exhaust switching valve. The main and auxiliary barrels are respectively provided with water inlet and water outlet one-way valves; a first outlet of the gas inlet switching valve is connected with the auxiliary barrel through a high pressure gas pipe; a second outlet of the gas inlet switching valve is connected with the main barrel; a float ball type exhaust valve is arranged in the auxiliary barrel; when the liquid level of the float ball type exhaust valve in the auxiliary barrel is higher than a set position, the float ball type exhaust valve is closed, or the float ball type exhaust valve is opened; a first inlet of the gas exhaust switching valve is communicated with an exhaust port of the float ball type exhaust valve through a normal pressure gas pipe; a second inlet of the gas exhaust switching valve is connected with the main barrel; a controller for controlling the gas inlet switching valve and the gas exhaust switching valve to operate according to the liquid level is arranged in the main barrel, so that when the main barrel is controlled to drain, liquid is fed into the auxiliary barrel; and when the main barrel is controlled to be fed with the liquid, the auxiliary barrel drains, and the process is circulated to form continuous recovery and conveying of the high temperature liquid.

Description

technical field [0001] The invention relates to the technical field of energy-saving equipment, specifically a continuous recovery and delivery device for high-temperature steam condensate, especially a continuous recovery and delivery device for high-temperature steam condensate with a specific gravity of 0.8-1.1 controlled by a floating ball driven by steam or compressed air . Background technique [0002] In the field of production, the steam and high-temperature fluid generated by heat exchange equipment are precious thermal energy resources. At present, the steam and high-temperature condensed water in many common equipment are recovered openly or not recovered at all. Energy is wasted and at the same time pollutes the environment. In the recovery method, the spray condensate recovery system (for example: the closed condensate injection cycle recovery system disclosed by the Chinese Patent Document No. CN87210796, and the exhaust steam and condensed water recovery disc...
