A system, in certain embodiments, includes a spray device including a first liquid passage configured to flow a first liquid in a generally downstream direction toward a spray tip. The spray device also includes a second liquid passage configured to flow a second liquid in a generally upstream direction such that the second liquid impinges upon the first liquid at an outlet to the second liquid passage. The upstream direction is substantially opposite from the downstream direction.

1. A system, comprising: a spray gun, comprising: a first liquid passage configured to flow a first liquid in a generally downstream direction toward a spray tip;a second liquid passage configured to flow a second liquid in a generally upstream direction such that the second liquid impinges upon the first liquid at an outlet to the second liquid passage, wherein the upstream direction is substantially opposite from the downstream direction;a first mixing baffle downstream from the outlet to the second liquid passage, and including a first set of passages, wherein the first set of passages includes a first passage and a second passage angled toward one another in the downstream direction; anda second mixing baffle downstream from the first mixing baffle, and including a second set of passages, wherein the second set of passages includes a third passage and a fourth passage angled toward one another in a downstream direction;wherein the first set of passages of the first mixing baffle is circumferentially offset from the second set of passages of the second mixing baffle. 2. The system of claim 1, comprising a check valve disposed at the outlet to the second liquid passage and configured to block a flow of the first liquid into the second liquid passage, wherein the check valve forms a substantially annular orifice configured to provide a generally even distribution of the second liquid into the first liquid passage. 3. The system of claim 1, wherein the first mixing baffle and the second mixing baffle define a tortuous flow path. 4. The system of claim 1, wherein the first set of passages of the first mixing baffle is configured to direct liquid flows to impinge upon an upstream surface of the second mixing baffle. 5. The system of claim 1, wherein the first mixing baffle and the second mixing baffle each include at least two sets of passages. 6. The system of claim 1, comprising a static mixer disposed downstream from the second mixing baffle, and including a plurality of turning vanes each configured to split and rotate a liquid flow. 7. The system of claim 1, wherein the spray tip comprises an impingement tip including a plurality of converging exit orifices configured to direct streams of liquid toward one another. 8. The system of claim 1, wherein the spray gun comprises a liquid flushing system configured to provide solvent upstream of the outlet to the second liquid passage. 9. A system, comprising: a spray gun, comprising: a first liquid passage configured to flow a first liquid in a generally downstream direction toward a spray tip;a second liquid passage configured to flow a second liquid in a generally upstream direction such that the second liquid impinges upon the first liquid at an outlet to the second liquid passage, wherein the upstream direction is substantially opposite from the downstream direction;a check valve disposed at the outlet to the second liquid passage and configured to block a flow of the first liquid into the second liquid passage, wherein the check valve forms a substantially annular orifice configured to provide a generally even distribution of the second liquid into the first liquid passage; andat least one mixing baffle positioned downstream from the outlet to the second liquid passage, wherein the at least one mixing baffle is configured to mix the first liquid with the second liquid, and the at least one mixing baffle includes at least one set of two or more passages configured to direct liquid flows toward one another. 10. The system of claim 9, wherein the at least one mixing baffle defines a tortuous liquid flow path. 11. A system, comprising: a multi-liquid mixing device, comprising: a first mixing baffle including a first set of passages, wherein the first set of passages includes a first passage and a second passage angled toward one another in a downstream direction; anda second mixing baffle downstream from the first mixing baffle, and including a second set of passages, wherein the second set of passages includes a third passage and a fourth passage angled toward one another in a downstream direction;wherein the first set of passages of the first mixing baffle is circumferentially offset from the second set of passages of the second mixing baffle. 12. The system of claim 11, wherein each mixing baffle includes at least two sets of passages. 13. The system of claim 11, wherein an angle between the first passage and the second passage, or an angle between the third passage and the fourth passage is greater than approximately 45 degrees. 14. The system of claim 11, wherein an angle of the circumferential offset between the first set of passages and the second set of passages is greater than approximately 45 degrees. 15. The system of claim 11, wherein the first set of passages of the first mixing baffle is configured to direct liquid flows to impinge upon an upstream surface of the second mixing baffle.
